In February 2023, DRA hired Iowa -based RDG Planning & Design (RDG) to research, develop and deliver a comprehensive development plan for Chaplain Schmitt Island (the Island). The plan defines concrete next steps related to the community's vision of the Island being developed as "Dubuque's Gateway to Entertainment and the Mississippi." As a part of this work, RDG was tasked with summarizing existing master plans for the Island, as well as completing more detailed studies on the Island's current infrastructure, natural resources, development potential, potential economic impact and more. The visioning and planning work being done by RDG has been overseen by a steering committee to help guide the creation of this Development Plan throughout the entirety of the process. This steering committee is comprised of representatives from the DRA, City of Dubuque, RDG Planning & Design, AECOM, Strand Associates, Inc., and Impact7G/ Eocene Environmental Group. The steering committee has met weekly for the past 18+ months and has put together the attached Development Plan for the Island. During this time, the steering committee has brought draft plans to City Council during public work sessions. Upon completion of a proposed final draft of the Development Plan, which addresses many of the City Council's goals and priorities, steering committee members conducted public input through multiple channels: a public survey available online, a public open house meeting, and presentation to both the Long Range Planning Advisory Commission and the Parks & Recreation Commission. Both the Long Range Planning Advisory Commission and the Parks and Recreation Commission unanimously recommended approval of the Chaplain Schmitt Island Development Plan.

BACKGROUND In 2014, a Master Plan for Chaplain Schmitt Island (the Island) was adopted which laid out key community desires for the creation of a destination area on the Island. This was followed in 2017 with a Placemaking Plan, which was updated in 2022 to include an amphitheater and improved trails, resulting in the City being awarded a number of grants to accomplish these projects. DISCUSSION In February 2023, the DRA (gaming and entertainment facilities which provide for social, economic and community betterment and lessen the burden of Dubuque city and area government, while contributing to the growth and viability of Dubuque area tourism) hired Iowa -based RDG Planning & Design (RDG) to research, develop and deliver a comprehensive Development Plan for the Island which would outline strategies, budgets, and timelines to implement specific projects informed by the vision set forth in the previous plans. The Development Plan defines concrete next steps related to the community's vision of the Island being developed as "Dubuque's Gateway to Entertainment and the Mississippi." As a part of this work, RDG was tasked with summarizing existing Master Plan and Placemaking Plan for the Island, as well as completing more detailed studies on Page 547 of 1050 the Island's current infrastructure, natural resources, development potential, potential economic impact and more. The visioning and planning work being done by RDG has been overseen by a steering committee to help guide the creation of this Development Plan throughout the entirety of the process. This steering committee is comprised of representatives from the DRA, City of Dubuque, RDG Planning & Design, AECOM, Strand Associates, Inc., and Impact7G/ Eocene Environmental Group. The steering committee has met weekly for the past 18+ months and has put together the attached Development Plan for the Island. During this time, the steering committee has brought draft plans to City Council during public work sessions. Upon completion of a proposed final draft of the Development Plan, which addresses many of the City Council's goals and priorities, steering committee members conducted public input through multiple channels: a public survey available online, a public open house meeting, and presentation to both the Long Range Planning Advisory Commission and the Parks & Recreation Commission. Input from each of these sources is attached to these materials. Both the Long Range Planning Advisory Commission and the Parks and Recreation Commission unanimously recommended approval of the Chaplain Schmitt Island Development Plan. BUDGETIMPACT Future budgeting decisions will impact the ability of the Development Plan's recommendations to come to fruition. RECOMMENDATION I respectfully request City Council adoption of the attached Chaplain Schmitt Island Development Plan via the attached resolution.

A key strategy within this plan was the establishment of an island resort destination. A mixed use area that would help attract residents, improve the quality of life and offer tourism opportunities. Some of these ideas have started to emerge in the built form, including an expansion of the Q Casino + Resort, enhancements to the trail system and transportation improvements through the recently awarded Federal Raise Grant. Given these improvements — and the fact that the Southern portion of the island has not experienced the same level of investment, clarity is needed on what the highest and best uses of these lands are. Within the 2014 plan, additional redevelopment uses included sports tourism, recreational/passive sports and residential development — all would be pivotal to the island's success. While the strategies behind this vision have merit, further study was needed to understand the potential costs and economic impacts of what is feasible as significant changes (Covid-19, interest rate hikes, inflation, etc.) have occurred throughout the world and within Iowa over the past several years, impacting the greater Dubuque region. As we look ahead into the sections of this document, the Schmitt Island Development Plan provides a comprehensive framework to prioritize, clarify, and move development forward, helping to create a unique, one -of -kind island destination on the Mississippi. Process The planning process was iterative and took a systematic perspective, completing the appropriate level of due diligence that is necessary to build investor confidence, identify potential pitfalls and to create a program for development that contains the right mix of uses, with an ultimate goal of creating a vibrant, destination development. Within the plan, special attention was given to these critical factors: • Market Research. What uses are in demand within the Dubuque region? Are there gaps that are best served on Schmitt island? • Financial Feasibility. Are the uses financially feasible — what level of incentive is needed to make the improvements a realistic project? • Resiliency and Flooding. What improvements are needed to protect future investments? Are there ways to construct buildings that resilient? • Natural Resources. A defining characteristic of the island — what should be done to reconnect the residents of Dubuque and Island users to the landscape? • Connectivity. What modes, improvements or strategies are necessary to help improve the connectivity and circulation on the island? Together, these factors have been evaluated, providing clarity for what could be, while addressing the myriad of questions that arise as development opportunities are initiated. Action & Next Steps As you read through the plan and view the illustrations of the proposed development, several critical actions are needed to advance the project (amongst many more high priority improvements). This includes working with the Department of Interior and the State of Iowa to remove the use restrictions on the Gerald "Red" Mc Aleece Park and Recreation Complex, update the Schmitt Island Planned Unit Development Ordinance to include residential as a permissible use and work with the City to understand the potential geotechnical considerations on the island. Completing these items will help provide clarity and build investor confidence, ultimately continuing the momentum generated by this planning effort. 2 3 4 5 6 7 8 9 A g 41110�tL SCHMITT ISLAND I Development Plan NNW"= R4L .... �----:..•-ems - _ - - _ OW al Q t - ► !

It's pit W.� .4301 to SCHMITT ISLAND I Development Plan Development Plan I SCHMITT ISLAND » SCHMITT ISLAND Background & Momentum Why a Development Plan Now? Over the past year, multiple stakeholders convened, analyzed and informed the vision for Schmitt Island. While the notion of a development plan is not new, the viability and feasibility of the prior master plan's improvements (impacted by market, environmental and other concerns) have not been analyzed to the extent needed in order to make informed development decisions, invest capital or prepare the sites for development. This plan provides a summary of the analyses completed, markets contemplated, infrastructure needed and the other "development systems" that are necessary parts of a development process. Vision The long-term vision for the island is to create Dubuque's "Gateway to Entertainment and the Mississippi," a regional destination where people of all ages, abilities and backgrounds can experience Dubuque's beauty and high quality of life. This plan sets out to achieve several critical objectives: • Leverage Existing Investments. Multiple projects are in design or construction on the island, including a 155 Million Dollar Casino + Resort development, the planning portion of the City's recently awarded Federal RAISE Grant, a pedestrian trail improvement that connects the Veterans memorial to the mainland and infrastructure investments to help improve sanitary sewer service. 1. Attract New Development. Identify ways to attract private investment from local, regional and national sources, serving as a premiere waterfront destination for Dubuque's riverfront development. 2. Market Alignment. Ensure that commercial, residential, entertainment and recreation uses are right sized and in sync with the local and regional markets. 3. Identify Potential Policy Barriers. Review existing city ordinances or policies that may unreasonably slow or negatively impact how development occurs on the island. 4. Floodplain/Floodway Evaluation. Evaluate the regulatory impacts on floodplain and floodway development, specific to this development initiative. S. Beautify the Island. Identify ways to restore and enhance the island's natural resources and connection to the Mississippi, which is the island's differentiating factor. 6. Circulation Evaluation. Review and enhance the island's infrastructure and mobility opportunities, improving the access to indoor and outdoor recreation. 7. Be Strategic. Determine and prioritize the highest and best development opportunities given these objectives/decision-making lenses. 10 3 4 5 6 7 8 9 A g !04 SCHMITT ISLAND I Development Plan Rendering of new casino development. Image: DLR/ Q Casino + Resort Development Plan I SCHMITT ISLAND 15' Page 556 of 1050 Background & Momentum Development Plan Overview Commissioned by the Dubuque Racing Association (DRA) and supported through numerous conversations with the City of Dubuque, this development plan uses a strategic approach that integrates the island's physical systems into the final development plan. This approach fuses the best -case scenario for resiliency, development, ecology, mobility — and economic feasibility — into a robust 20-year vision. The DRA led weekly discussions in collaboration with the planning team to help define the island development program based on market research. Early strategies were tested and vetted with multiple developers who have completed significant volumes of work in Iowa. Further, feasibility was evaluated by key stakeholders including the United States Army Corps of Engineers and the City of Dubuque. Recommended next steps are included later in this document. While this development plan can be seen as a refinement to the prior plan efforts, it also served as the final sieve, creating clarity for the improvements contemplated. On the following page is a summary of the key elements from concurrent design and engineering efforts along with prior plans that have been woven into this development plan.

Vibrant Community. This development plan identifies a number of improvements that promote improving the physical and emotional health of those that visit the island including destination play, hospitality, trails, "eatery- tainment" and similar placemaking strategies. Improving pedestrian safety and vehicular circulation are a high priority. 2. Financially Responsible, High Performance City Organization. This development plan offers multiple strategies that help create a resilient future through financially responsible strategies for all, including additional property tax and lease income growth. 3. Robust Local Economy. The Schmitt Island Development Plan identifies multiple improvements that help diversify the community and region's economy — including waterfront living, destination development, access to jobs and a strong connection to the natural environment. No other place in Dubuque is as physically connected to the Mississippi river as Schmitt Island — this is a key differentiator from all of Dubuque's riverfront. 4. Livable Neighborhoods and Housing. Housing is a key goal that helps ensure vibrancy and opportunity are present on the riverfront. S. Sustainable Environment. The natural resource restoration opportunities on the island are significant. This plan identifies clear strategies to restore and revitalize the vegetation and natural amenities, helping improve the physical, social and mental health of all who use the island. 6. Connected Community. This plan identifies a series of alternative transportation opportunities, including bike trails, paths, water taxis and ride share opportunities that will help improve access and mobility within and around the island, creating a direct connection to some of Dubuque's most disadvantaged census tracts. 7. Diverse Arts, Culture, Parks and Recreation Experiences and Activities. A key goal for the city, this strategy is woven throughout the development plan. Expectations for high quality design, an artful amphitheater and unique "placemaking" strategies will elevate the island's standing, appeal and vibrancy. 8. Partnership for a Better Dubuque. Multiple public and private development opportunities will include improvements that everyday citizens can enjoy. From the public fishing access to bike paths, riverfront promenades and destination play areas, this plan is for the people who call Dubuque home — and those who will call it home in the future. Development Plan I SCHMITT ISLAND _117` Page 557 of 1050 Background & Momentum 2014 Master Plan The 2024 Schmitt Island Development Plan brings clarity to the 2014 Master Plan strategies and opportunities, evaluating their feasibility, current demand (as of this writing the 2014 master plan is 10 years old) or desire and distills the concepts into an action plan. For more detailed information and to review the 2014 plan, please refer to this plan's appendix. The 2014 Master Plan was sponsored by the City of Dubuque. Key "big picture strategies" that have been carried forward into this plan include the following: • Master Plan Goals. Including a connected riverfront, celebrating the island, putting your feet in water and spending the day or night in any season. These goals have been woven through the development plan and are as relevant today as they were in 2014. • Master Plan Framework. The "three ideas" introduced on page 29 of the 2014 report remain strong organizing factors for island development. • Master Plan Site Analysis. In general, the analysis work included in the master plan was carried forward into the development plan. Minor exceptions include changes to the current tenants that lease land from the city, minor changes to land use and facilities. A new Veterans Memorial has been constructed and a new trail is currently being developed along Admiral Sheehy Drive, connecting the memorial to the city. • Island Destination. The spirit of creating an island destination remains a high priority. Market analysis suggests that residential uses (built through a lens of resiliency) are needed, as is a marina village. • Peosta Channel Bridge. The bridge connects back to the mainland and serves as a second point of egress from the island. • Tunneling under Highway 151 to connect the island. This improvement helps connect the North and South sides of the island, improving connectivity. Key high level strategies from the 2014 Master Plan that are no longer viable or supported (based on the systems approach) in 2024, include the following: • Economics. The 2014 Master Plan economics are from a pre-Covid world. Much has changed. • Island Destination. While the idea of maximizing the development on the south side of the island remains a key strategy, the specific tactics and uses have been revisited — especially for the ballfield site (Gerald "Red" McAleece Complex). The current market analysis does not support developing office space or traditional retail spaces, nor does it indicate a need for a minor league baseball stadium. w _s Option 1: Housing Option 2: Retail Option 3: Minor League Baseball 1 0 3 4 5 6 7 8 9 A g !44 SCHMITT ISLAND I Development Plan 7 I' _ qwapWMENi 050 4b Background & Momentum 2017 Placemaking Plan Please see the appendix of this document for a full copy of the 2017 Placemaking Plan. The 2017 Schmitt Island Placemaking Plan was developed by the Dubuque Racing Association to help kick start and bring clarity to some of the initiatives proposed in the 2014 Master Plan. The plan was authored by RDG Planning & Design and focused on amenities that were not under the control of the private sector. Key placemaking plan strategies that have been carried forward into this plan include the following: • Vision and Mission. The placemaking plan's vision and mission remain true today and have been adopted as the guiding vision for the overall island. • Island Destination. - A destination boardwalk creates an iconic entry into the island. - A landmark tower located at the island's north end. - Revisiting the future of Miller Riverview Park. - A robust trail/boardwalk system. • Highway 151. Light the bridge. • Amphitheater. • 2017 Design Guidelines & PUD. During the development of the 2017 Placemaking Plan, strategies were put in place to allow the island to function as its own destination and district — hence the desire to have it be regulated independently from other areas of the community. In large part this was due to the island's unique history (landfill, flooding, etc.) and location. These generated a need to think creatively about how development should occur. During the development of the PUD, there were concerns over traditional residential development taking place, adjacent to a resort. Therefore, residential was removed as a permitted use. Post-Covid, the market has changed and there is new demand for waterfront living, with a desire for direct access to amenity rich environments. This shift is reflected in this 2024 development plan, showing a robust marina village that incorporates residential uses. • 2022 Island Master Plan Update. During the summer of 2022, RDG prepared a revision to the 2017 Placemaking/2014 Master Plan that incorporated an amphitheater venue and an improved trail system into the lands currently owned by the City of Dubuque, located at the former site of Greyhound Race Track. This plan was used to seek grants from by the State of Iowa through the "Destination Iowa" grant program. LEGEND 1. Memorial Enhancements 2. Trail and Screening 3. Trail Connection 4.

Casino + Resort Separate from this plan — but a critical investment and development driver - are the significant improvements already in the works or underway. The Q Casino + Resort and DRA are in the midst of a $155 million redevelopment of the Q Casino + Resort. A temporary casino has been constructed and construction is under way for a new casino floor. A groundbreaking ceremony has been held for a new hotel. A family entertainment zone will be completed by this winter to welcome families indoors. And funding has been awarded to build an outdoor amphitheater, to open in summer 2026 with the support of Destination Iowa. Trail Improvements In 2022, the City received a grant, sponsored by Representative Ashley Hinson, to construct a trail from the East end of the 16th Street bridge to the Veteran's Memorial. This work was identified in the Placemaking Plan and is under construction. RAISE Grant In 2023, the City of Dubuque received a RAISE Planning Grant award (also known as 16th Street improvements) through the US Department of Transportation to design a railroad overpass connecting 14th Street to 16th Street, developing a green street along Elm and creating a series of roundabouts and trails along 16th Street to Schmitt Island. These improvements culminate with a roundabout proposal on Schmitt Island, significantly improving island safety and connectivity. Ice Arena The island's ice arena gained major support for updates and changes with its rebranding in September 2023 as ImOn Arena, supported by ImOn Communications from Cedar Rapids. Looking Ahead The Schmitt Island Development Corporation (SID) was formed as a nonprofit organization in 2022. specifically to help undertake, lk manage and facilitate development projects on the island, and to facilitate charitable contributions toward that end. SID's website (https:// schmittisland.com) was launched as a way to build momentum for island development and to share information with residents and visitors about changes that are planned and occurring on the island. The establishment of SID is a key step in promoting the island's potential to the broader region, including non -Dubuque -area developers. Additionally, as a nonprofit, SID can apply for, request and receive grants and awards that might not be available to city or private -sector entities. Throughout the 2024 Schmitt Island development planning effort, a number of key decisions have helped provide clarity and investor confidence in the future of the island. These clarifying factors are explored in this document and have been vetted through objective, market driven measures along with subjective and informal input from policymakers and developers. 1 3 4 5 6 7 8 9 A g ! 22` SCHMITT ISLAND I Development Plan SCHMITT ISLAND Page 561 of 1050 SCHMITT ISLAND Page 562 of 1050 Vision &Development Program Chaplain Schmitt Island: Dubuque's Premier Waterfront Destination The plan intends to strategically maximize the island's potential to its highest and best use - improvements that are both good for the private sector and also provide a high return to the public, with opportunities to enjoy all that Schmitt Island has to offer. Additionally, to maximize the island's connection to the urban core so that it is easy to visit using all transportation modes. Planners gave careful consideration to regulatory frameworks, cost structures and policy landscapes. The planning team conducted developer interviews, stakeholder meetings, market research and financial feasibility analysis. Studying this data, it became clear that a development plan for the island needed to include a residential component. The current island planned unit development restricts residential development, which ultimately fails to capitalize on the island's potential as a premier destination for tourism and recreation. Hence, a pivotal aspect of the strategy involves revisiting these policies to unlock the island's full potential in recreation, tourism and amenity opportunities. 1 E2Tw 4 5 6 7 8 9 A g 40<tSCHMITT ISLAND I Development Plan Chaplain Schmitt Island anchors the North end of Dubuque's waterfront and is a front door into the City and Downtown. Development Plan I SCHMITT ISLAND 29` Page 563 of 1050 Vision &Development Program As Schmitt Island enters the next phases of development, maintaining it's unique relationship with the natural environment, improving connectivity and creating vibrant public spaces will be fundamental to achieving the plan's vision. These items contribute to a high quality of life while also creating a draw for visitors. This includes: • Focusing on identifying the island's brand — it must provide a unique mix of uses that are different from existing developments in Dubuque • It must be memorable for all — creating great civic destinations and reconnecting to the river. -Reducing reliance on the automobile, creating walkable, bikeable and connected destinations that are safe and well designed. • Reducing vehicular speeds into and out of, as well as around the island — while simultaneously providing additional mobility offerings for entertainment events — pedestrians should be prioritized over vehicles. • Restoring the natural areas to focus on the "long views" into and out of the island while clearly delineating the arrival movements. • A high level of care for the spaces that exist today — and those created in the future. These spaces should be maintained to the highest level, beautified and well cared for throughout all of the seasons. Together, developers, the Q Casino + Resort, the City of Dubuque and community leaders must collaborate around achieving the vision and hold it with the highest regard. Expectations for good design and planning should be first and foremost creating a dynamic island destination. 1 E2Jm 4 5 6 7 8 9 A g !04 SCHMITT ISLAND I Development Plan Highw y 151/61 Pl�&564 of 1050 Vision &Development Program North Half Detail Plan LEGEND Amphitheater: 1.

By incorporating tucked - under parking, a U-shaped building layout will optimize space utilization, fulfill parking requirements and accommodate the desired density of units. The complex would be expectd to balance high enough price points to maintain a rate of return that supports the development. This building design can meet the needs of empty nesters and other target market segments, with amenities such as large openings and river -facing decks to enhance the overall appeal. Some units may serve as an Airbnb style rental or offer longer stay visits. The site's adjacency to the marina may mean that, in future, some boat slips could be set aside and dedicated to residents of this development.

Based on comparable hotel projects, approximately 107 hotel keys will be needed to make this a viable project. The hotel could also support the ice arena with needed food and amenities, and the two could devise tailored event experiences. The planned hotel becomes slightly less viable for the island if there is no expansion to the ice arena (see below).

Travelling ice hockey teams would benefit from an additional ice rink. A local Division 3 institution has expanded its offerings and now has a team that make use of a second sheet of ice. This plan also recommends that the ice arena operator increase hosting, tournament hockey events, for high school/traveling teams. Such events attract parents and family members, and the arena addition would include an entertainment center to provide a host of different experiences for those visitors.

The tower flanks the proposed amphitheater project, with a boardwalk connecting the two. The tower is a beacon: a visible welcome and gateway into Schmitt Island, overlooking the Mississippi and the lighted bridge between Dubuque and Wisconsin. The tower is another opportunity for year-round programming, with its observation deck, restrooms and elevator. The observation tower could even be structured to include ziplining or other active recreational opportunities unique to the region. Boardwalk The boardwalk idea was part of RDG's 2017 placemaking plan for the island. Miller Riverview Park would be renovated to accommodate both camping and a boardwalk, with camping including RV locations, which could also be scattered around other areas near the casino. Camping is contemplated in and around the amphitheater area as well, with a variety of options including tree house camping and secluded but amenity -rich camping experiences that focus on integrating nature. Highway 151 Bridge Lighting The iconic Highway 151 bridge is perfectly situated to be a colorful gateway to Iowa and to Chaplain Schmitt Island.

From a regional development standpoint, given the unique nature of Covid's impacts relative to past recessions, it is important to delineate the following distinctions and their implications for Greater Dubuque and Schmitt Island, specifically the extent to which pre-existing economic trends in place across the city re-emerge post-Covid; or, whether short-term trends due to Covid strengthen and dictate different future trajectories. In general, the Dubuque area has experienced a faster pace of population growth since 2010 relative to historic trends, in part due to an apparent increase in remote work. A majority of regional growth has tended to concentrate in the City of Dubuque and Dubuque County, with more rural areas staying largely stable, more so in Iowa than in northwestern Illinois or southwestern Wisconsin, where population and income growth have been more modest since 2010. This point reinforces the need to look at stronger destination markets, including Cedar Rapids, Des Moines, Rochester (MN), Madison, Milwaukee, and Chicago to drive visitor market growth toward Dubuque. With the region now emerging from economic volatility since 2020, planners leveraged cell phone data from a source called Placer.Al to provide greater clarity regarding how existing destinations in the area — especially Schmitt Island - have recovered since 2020. Planners were able to look at the strength of tourism, how many people visit for events such as hockey games, Os� and how much time they spend on the island. The longer people stay in the area, the greater the economic growth. As shown in the following charts, while Schmitt Island is not the largest visitor destination in the region (Kennedy Mall, Downtown Dubuque, and the Port of Dubuque are larger), the island has sustained significantly longer visitor length of stay relative to peer destinations. In general, effective tourism development strategies seek to extend visitor length of stay.

One direction could be a strategy that aligns with Dubuque's current residential base, and another could be a strategy aligned with the marina area, which might be most attractive to people in the wider region rather than just the local market. Team market analysis revealed two consequential findings: 1. Regional Housing Market. Slow to deliver new housing product relative to increasing population, and home prices have increased. 2. Local Apartment Market. Currently, offers a limited supply of premium high -end projects. Regional market analysis reinforced a similarly limited supply of contemporary premium apartments in the region: • Built in 2022, Andante (Eau Claire, WI) is a 76-unit mixed -use development with approximately 8,000 square feet of ground floor commercial space. The building is located along the riverfront promenade and has direct connections to the public trail system. Built in 2020, Kingston Village (Cedar Rapids, IA) is a 50-unit building with a range of amenities including a green rooftop, high- speed internet as well as high end finishes. • Built in 2022, 400 River (Davenport, IA) is a 55-unit apartment building with modern finishes. Amenities include a rooftop lounge with grills, TVs and fire pits. These developments all rent for premiums relative to the market average within their community, as shown below. Residential is seen as an opportunity for Schmitt Island, particularly if supporting amenities (including marina) can be leveraged. 30 Industrial Consistent with Midwestern trends, local industrial markets have performed well, as evidenced by steadily decreasing vacancy levels and steady rent growth. Growth has been tied to steady demand for e-commerce facilities, as well as growth in third -party logistics services (both in particular during Covid). Given limited land availability on Schmitt Island and typical parcel sizes for modern industrial real estate, industrial use is not seen as appropriate for the island. Retail Consistent with Midwestern trends, demand and supply for retail space have steadily come into better alignment as the impact of the "retail ESLAUV Average Rents 1 2 131_= 5 6 7 8 9 A g !44 SCHMITT ISLAND I Development Plan apocalypse" has faded since 2020. At the same time, retail markets are also adjusting to significant growth in the share of transactions which are initiated online (30-50%), which has implications for sales tax revenue. Given these realities, it is expected that future retail opportunities on Schmitt Island will need to be targeted, with emphasis on restaurant and entertainment / destination oriented activities. Office Reflective of growth in remote / hybrid work arrangements since 2020, near term demand for office use has softened, with increasing vacancy for older (pre <2000) office buildings with limited amenities. While office markets are expected to recover, new office projects will likely need to be located in more amenity -rich, mixed - use environments. Development Plan I SCHMITT ISLAND 89' Page 593 of 1050 SCHMITT ISLAND Page of 1050 Economic Feasibility Given findings regarding local real estate markets identified in Section 3, our approach for Section 4 "Economic Feasibility'; has focused on conceptual financial analysis of potential mixed - use development on Schmitt Island to support public policy development around future development on Schmitt Island. The essential elements which have emerged during the analysis include: Residential Supply. Does not appear to be keeping pace with demand across the Dubuque region, with an apparent opportunity for roughly 400 units, currently at above -market rents. Housing Market Potentials. Slowing in part by currently high construction costs (linked to inflationary challenges since 2023). There are reasonable expectations that construction costs will moderate in the next 12-14 months, which will be supportive of project feasibility. Grow Tourism. The plan is anchored by realistic expectations to expand tourism (both more tourists and extended length of stay), to penetrate a consequential visitor market within a three-hour drive time; roughly 17.2 million people. its population, meaning that with growth, additional retail offerings are reasonable. For Schmitt Island, the expectation is that destination retail offerings will be a supporting use on the island. • Office Demand. Expected to remain weak in the near term due to a well -documented increase in remote and hybrid work arrangements. • Environmental Constraints. On this island, environmental constraints will be an important factor to redevelopment costs and focus. Without flood mitigation, the highest and best use options for the island will be limited to activities related to harbor operations. With flood mitigation, we see the highest and best use options expanding to include permanent real estate development. • Public Policy. As land on Schmitt Island remains in public sector ownership, the analysis reinforces the need to clarify public policy expectations regarding the potential sale of public property on the island versus use of ground leases for private development, as well as the term of ground leases (potentially to 75-95 year terms). • Retail Market. These findings Net Proceeds. The project has indicate that Dubuque is capturing interesting potential to generate retail activity generally equal to net proceeds for the City of Dubuque across ground lease revenue as well as property & sales tax revenue. • City Role. Clarification of the role of the City in supporting private development on Schmitt Island, inclusive of several inter -related factors: • Confirming minimum public investment to elevate sites beyond 100-year flood plain minimums alongside additional public infrastructure needs for parks, boardwalks, and open space improvements. • The extent to which development on the island generates sufficient cashflow to recover public infrastructure costs. • Need for the City to formally participate in day-to-day project decision -making in real estate development projects. • The unique role of the Q Casino + Resort, owned by the City of Dubuque, in facilitating master plan implementation. 1 2 3 4 6 7 8 9 A g _44 SCHMITT ISLAND I Development Plan Financial Analysis Approach As final policy recommendations for future use of the island remain in debate, the following narrative is intended to summarize possible strategies for structuring redevelopment of Schmitt Island. Specific scenarios within the master plan vision have been tested using conceptual financial analysis approach, presuming either fee simple or ground lease -based developer approaches, as summarized in general terms below: Developer: This option includes the sale of the parcels of land to a developer wishing to self -develop the land for either a hold or sale scenario. In this structure, the City of Dubuque would have limited to no share in the design, construction, financing, and implementation responsibilities. Advantages of this structure to the City of Dubuque are that it reduces the development risk by sharing it to the developer. The trade-off of this structure is that it reduces the Island's long-term financial potential by transferring long-term returns with the developer. Ground Lease: Dubuque can choose to outsource 100% of the development to a developer. In this scenario, Dubuque would ground lease the entire development to a developer for an annual ground lease payment to be negotiated. The developer would control 100% of the project decisions, including design, construction quality, tenant mix, and delivery method. Dubuque would have the ability to shape some of the project concepts and set some minimum project design standards, through zoning/ PUD oversight. While this scenario reduces public sector risk and theoretically provides a basic level of guaranteed income, it also significantly reduces control over design and implementation; it also limits upside financial potential once the project stabilizes. Development Plan I SCHMITT ISLAND 93` Page 595 of 1050 Economic Feasibility The conceptual financial analysis is built around a goal seeking approach to identify a tolerable level of private investment based on a minimum rate of return goal for a "typical" developer. By association, identified investment costs that fall beyond the rate of return goal would need to be absorbed by the City of Dubuque through public investment, acting as a catalyst to unlock private investment. The analysis solves for TIF infrastructure need assuming either a minimum 20% unleveraged IRR or an 8% yield on cost (NOI/Capex). Three scenarios have been assessed: 1. Status quo operations for the duration of the marina lease; 2. Improved marina development with residential option; and 3. Improved marina development without residential.

Additional considerations: • The Improved Residential scenario will require public infrastructure improvements to elevate the site out of the floodplain. • Both the Improved Marina and the Improved Residential scenarios likely require longer ground lease terms (>50- 75 years). • From an employment standpoint, investments in marina enhancements have potential to yield enhanced employment benefits relative to the status quo.

Low areas are dominated by invasive woody and non -woody plants, and low -quality opportunistic native species. Upland areas are low -quality successional woodlands of non-native invasive and low -quality opportunistic native species surrounded by dense native and non-native shrubs and vegetation. Restoration Objectives Considering restoration of the ecology of the island, these six objectives come into focus: • Create spaces with improved access and managed vegetation for public use and enjoyment, and a unique outdoor recreational experience for connecting with nature. • Remove invasive species from all restoration zones. • Selectively thin low -quality native non-invasive species to promote healthy growth of remaining specimens. • Plant site -appropriate native tree species to improve woodland quality and diversity. • Identify and improve potential wildlife habitat sites. • Develop ongoing maintenance protocol for long-term preservation and enhancement of restoration efforts. Restoration Zones In 2023, the naturalized areas of the island were inundated by spring floods followed by drought conditions. In May/June of that year, Impact7G completed a desktop survey and field assessment of ecological conditions and subdivided the island into seven restoration zones. Impact7G walked the naturalized areas, documenting areas of distinct ecological variability and unique ecological components such as distinctive vegetation communities, invasive species, erosion and any other factors of ecological significance. Using this assessment, a series of base maps were developed using ArcGIS PRO software (See Figure 6.1). GIS analysis and mapping provides accurate areas and quantities for use in budget forecasting. Maps also illustrate site conditions, show the visual extent of management needs and are a critical tool for communicating management objectives. 1 2 3 4 E5T= 7 8 9 A g 404 SCHMITT ISLAND I Development Plan I% F,_WF� LEGEND King Rail Woods Heron Pond Woodland Edge Naturalized Lowlands Hip -Camp Open Lowlands Open Uplands 0 250 500 1,000 Ft Development Plan I SCHMITT ISLAND 103' 0 250 500 1,000 ® Ft Page 600 of 1050 Ecological Restoration Zones In addition to identifying needed timber stand improvements and other vegetation management, researchers found surface trash from previous landfill activities and debris washed in with floods at several locations.

Designs could incorporate some places that allow observation and integration of beaver activities into the island experience. Trash and debris found on the island. Evidence of wildlife and habitat. King Rail Woods & Heron Pond These two areas (See Figure 6.2) are dominated by open water with forested floodplain dominated by silver maple and cottonwood along with invasive white mulberry. Box elder, honey locust and hackberry were also noted. These zones present an opportunity to restore habitat for the endangered King Rail (Rallus elegans). The King Rail's ideal habitat complex consists of dense, emergent vegetation interspersed with openings that dry out during brood rearing. They prefer shallow freshwater marshes with a dense cover of grasses, cattails, rushes and sedges with water depths ranging from moist soil to 46 (cm) at nest sites and generally <10 (cm) at foraging sites. Foraging habitat before and after breeding is typically dense, emergent vegetation with standing water up to 25 (cm) deep. Foraging habitat for the King Rail during brood rearing consists of more open mudflats with water up to 8 (cm) deep. This plan recommends that an ISA Certified arborist identify higher value trees to remain. Restoration efforts should focus on King Rail _f 1 2 3 4 E5jm 7 8 9 A g !04 SCHMITT ISLAND I Development Plan habitat open water (>25%) and emergent herbaceous vegetation, with many open water -vegetation edges. These areas have abundant aquatic invertebrates and there is small variability in ground level to create a mosaic of moisture levels and cover types, such as shallow water, moist soil, hummocks, swales and dry patches. Vegetation management should include removing invasive species, ashes and weedy species and replanting/supplementing with native, drought and flood tolerant tree and shrub species such as sycamore, pecan and river birch, indigo bush, meadowsweet and other native species. Amenities for this area might include bird blinds, bird identification tools, updated trails and access points along with a connection to the Environmental and Recreation Outpost. LEGEND King Rail Woods Heron Pond 0 250 500 1,000 ® Ft Development Plan I SCHMITT ISLAND 105' Page 601 of 1050 Ecological Woodland Edge The woodland edge (See Figure 6.3) consists of higher -elevation forested edges and slopes which generally include even -aged, early successional forests dominated by invasive species including buckthorn (Rhamnus cathartica), white mulberry (Morus alba), tree of heaven (Ailanthus altissima), dames rocket (Hesperis matronalis), oriental bittersweet (Celastrus orbiculatus) and Siberian elm (Ulmus pumila). Noted natives include hackberry (Celtic occidentali), cottonwood (Populus deltoides), box elder (Acer nugundo) honey locust (Gleditsia triacanthos), green ash (Fraxinus pennsylvanica), and indigo bush (Amorpha fruticosa). The understory was dominated by raspberry (rubus occidentalis), riverbank grape (Vitis riparia ) Virginia creeper (Parthenocissus quinquefolia), nightshade (sp), and Canadian goldenrod (Solidago canadensis). The woodland edge is the most visible to the public and would benefit from more "curb appeal" This plan recommends that an ISA Certified arborist identify higher value trees to remain and focus on removing invasive species, ashes and weedy species to create an open edge that highlights the adjacent lowland. Replanted trees and shrubs (streetscape sizes) should be selected for shade and interest while keeping an open canopy. In addition, amenities could be added to encourage bird watchers, such as promoting bird and pollinator habitats along with trail improvements that encourage people to explore from the trail and/or enter into the space and explore the lowland forest. Naturalized Lowlands The naturalized lowlands (See Figure 6.4) are dominated by cottonwood and silver maple with abundant wooded debris and flood deposits. Invasive species included buckthorn, reed canary grass, Siberian elm, and white mulberry. Areas of native understory were noted and included, elderberry, indigo bush, sedges, prairie ragwort, swamp milkweed, Virginia creeper, water smartweed and wild rose (Iowa state flower). Also noted were blackberry, box elder, green ash, hackberry, honey locust, pin oak, river birch, and riverbank grape (vine). It is recommended that an ISA Certified arborist identify higher value trees to remain and focus on removing invasive species, ashes and weedy species. The area should be planted with ecologically appropriate native trees and shrubs which are drought and flood tolerant. Trees may need to be protected from deer browsing and beavers. Native woody plantings can help stabilize and diversify the floodplain forests, can provide screening for sensitive wildlife and can begin a trajectory towards a more natural structure and healthier ecological community in this zone. Direct seeding (e.g., acorns) may be effective in this zone, but most woody plantings should be bare root or saplings (restoration grade smaller than 1 inch). It is best to wait a year or two before installing new woody vegetation, until the bulk of invasive management is completed. Material may be left in place or mulched. These would be good areas to add mowed open paths and natural trails to facilitate exploration. 1 2 3 4 E5T= 7 8 9 A g ! 106` SCHMITT ISLAND I Development Plan LEGEND Woodland Edge 0 250 500 1,000 ® Ft LEGEND Naturalized Lowlands 0 250 500 1,000 ® Ft Page 602 of 1050 Ecological Hip -Camp, Open Lowlands and Open Uplands While these areas are not naturalized, we do recommend that they offer a connection to the adjacent naturalized areas (See Figure 6.5).

The open upland zone - ••sue �N_ ,J _A� 19 is adjacent to Heron Pond and has outdated playground equipment and some signage in need of updates. The open lowland is a gateway to the island, with a pond which is edged with weedy and overgrown vegetation. For each of these zones, an ISA Certified arborist should identify higher value trees to remain and focus on removing invasive species, ashes and weedy species. The area should be replanted with ecologically appropriate native trees and shrubs which are drought and flood tolerant. Trees may need to be protected from deer browsing and beavers, and native plants and shrubs (pollinator species) with seasonal interest should be added.

The arborist should identify hazard trees and inorganic material/litter that needs removal and instruct field staff regarding restoration goals and procedures. Physical Removal Improvements noted here will require the use of hand or mechanized equipment to remove plant material. Chainsaws, hand saws and pruners, mechanical brush cutters and other cutting tools may be used to eliminate invasive and low -quality plant material. Mechanical Mastication/ Mulching In areas dominated by non-native and invasive species, vertical or horizontal masticators should be used, comprised of a large roller drum with titanium carbide teeth that spins at excessive speed to chop and grind problematic woody vegetation. Track loaders with rubber or steel tracks should be used to clear large patches of area. Primary physical limitations include excessive slope, ground conditions and size of trees. Once masticated, hand crews would follow behind and spray remaining stumps with glyphosate, triclopyr or imazapyr. This is an efficient, effective and practical solution to large areas riddled with unwanted vegetation. Basal Bark Herbicide Application A basal bark herbicide application should be used to eradicate invasive and low -quality woody species and may be applied at any time of year. Ester formulation of triclopyr is mixed with an oil -based carrier and applied to the trunk of the plant and absorbed through the bark. This is an effective dormant season control method. Large Tree Removal Identify low -quality or non-native trees to be removed. Depending on tree location, structure and potential to cause damage below, trees may be felled by a professional sawyer, girdled (cutting around the full circumference of the trunk to disrupt vascular tissue; may be left standing for nesting and habitat) or eradicated with the "hack and squirt" method that involves cutting into the bark and applying herbicide. Girdling is an effective technique, which would primarily be used for trees larger than 12-inch diameter at breast height. Chainsaws perform a circular cut, around %2-inch deep, to sever the cambium, rhytidome, and sapwood, resulting in loss of nutrients and water from the roots to the canopy. Siberian elms, white mulberry and a portion of black cherries will be eradicated using this technique. Trees can be left for snag recruitment where desirable. Maintenance (Adaptive Management) • A minimum of two (2) annual maintenance visits to each restoration zone. • Tree tube/stake maintenance. • Herbicide rings around newly planted trees to reduce weed competition. • Invasive species resprout spraying through all areas. • Identification of hazard trees and other management priorities. Development Plan I SCHMITT ISLAND 109' Page 603 of 1050 Ecological Management Summary Due to the prevalence of non-native and non-native invasive species, multiple opportunities are present for native species re -introduction on the island, which will benefit wildlife, pollinators and stand resiliency. Pocket areas of shrubland dominated by native plum species can be maintained for native wildlife foraging and habitat value. While aggressive, native gray dogwood does provide habitat and woodland ecotone value, and it can be beneficial to maintain this species in limited areas where appropriate. In addition, there is some benefit to using non-native aggressive herbaceous species such as reed canary grass for shading in some areas. Habitat/Brush Piles Most wildlife can benefit from man- made structures used to mimic natural habitat. Common techniques should enhance, restore and promote use by wildlife as escape cover, nesting sites, den sites and resting sites. Large, 8x8 foot brush piles may be placed along fencelines, edges and ridges close to trails to attract wildlife in places where animals can be viewed for educational purposes. Piles can be constructed using the ample source of cut woody biomass available. Largest cut material should be placed at the bottom of the piles to create a solid foundation, with smaller material at the top. Invasive Species Control Large swaths of invasive species reside in the restoration zones and will require focused efforts to eliminate them where possible. The level of energy spent on invasive species removal should always be placed in the context of long-term management budgets, expectations and objectives to be sure that those energies are not better served in other management areas. Non- native and invasive species are firmly established in the majority of wood- , shrub- and grass -land areas. The following is not a comprehensive list but includes species that are of particular note due to their widespread abundance on the island and general management tenacity. 1. Reed Canary Grass. (Phalaris arundinacea) Holding near total dominance in most grassland areas, this invasive grass allows very few other species to establish except in shady environments where it does not flourish. Native and non-native reed canary species have interbred to the point of being indistinguishable. This plant spreads primarily by rhizome but will also readily inter -seed into downstream areas. For this reason, management efforts should start in the upper reaches of watersheds and work down slope to minimize re -introduction. Chemical -based control methods of this plant are very intensive due to the nature of the rhizome; dormant nodes are not damaged by herbicide and can still activate when other parts of the plant are damaged, sending up new sprouts. 2. Garlic Mustard. (Alliaria petiolate) A 3-foot-tall flowering plant, garlic mustard is present to a small degree in many of the central mosaic woodland areas of the island. This plant produces copious seeds that are likely not fully germinating due to the shade but remain viable on the forest floor for up to a decade. With the introduction of more light, managers should fully expect the numbers of this plant to increase exponentially, thus appropriate management measures should be anticipated. Garlic mustard can be managed in a woodland when caught early enough but will become an endless carpet within just a few years. Pulling and removing the plant, spring woodland burns, mechanical destruction and timely spot herbicide applications are good management techniques. 3. Canada Thistle. (Cirsium arvense) This invasive thistle is present in scattered yet widespread populations through many of the drier grassland areas and the prairie reconstruction. Dense populations of this thistle are found within the eastern drainageways of the 1 2 3 4 E5Jm 7 8 9 A g SCHMITT ISLAND I Development Plan prairie reconstruction and pose a significant threat to the long- term resiliency and diversity of the prairie. This can be managed through appropriately timed mowing and spot herbicide applications. Do not mistake the prairie thistle and other native thistles for invasive Canada and bull thistles. Native thistles provide important habitat for pollinators, insects and food for birds, but are easily caught up in large scale thistle management efforts. 4. Siberian Elm. (Ulmus pumila) Native to eastern Asia, this tree quickly forms small to medium diameter tree thickets dense enough to outcompete most native species. Typical management involves removal and cut -stump herbicide treatment. S. Oriental Bittersweet. (Celastrus orbiculatus) This plant is a non- native woody vine that is overly Siberian Elm aggressive, and it can overwhelm native trees and shrubs. Oriental bittersweet is currently one of the most destructive non-native invasive plants found in Iowa woodlands (see brochure on management at http://www. iowadnr.gov/Conservation/ Forestry/Forest-Health). Pulling the plant out by the roots (be sure to get the entire root) can be a successful management method. 6. Common Buckthorn. (Rhamnus cathartica) A tall shrub or small tree that can be introduced into a forested area by birds. This plant can grow 5 to 15 feet tall in the understory of a forested area where it can become invasive and compete for more desirable native plants. Small plants may be hand -pulled and prescribed fire can be used for seedlings. Larger plants can be dug or pulled using a leverage tool such as a weed Oriental Bittersweet wrench. Girdling trees requires stripping the bark to expose the inner hardwood at a minimum of six inches, and can occur any time of year. Cut -stump treatment with glyphosate can occur in late fall. Cut -stump or basal bark spray treatment around the stem with triclopyr ester can occur in late fall through the winter. 7. White Mulberry. (Morus alba) White Mulberry should be killed standing by cutting flaps or single girdle with a chainsaw all the way around the trunk and treating these wounds with an herbicide labeled for such use. Chemicals used in performing these practices must be applied according to authorized use, label direction, and other federal or state policies and requirements. Do not use any chemical with the active ingredient picloram (i.e., Tordon) for this purpose.

For this reason, as master development planning efforts continue to advance at the island, it will be important to evaluate and understand the impact potential Mississippi River flood risks will have on the feasibility of various improvement projects being considered. This includes confirming compliance with applicable federal, state and local floodplain and floodway regulations that will govern whether potential improvements at the island are feasible from a regulatory, engineering and cost perspective. Existing Floodplain Mapping Review Figures 1 and 2 depict the regulatory Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) for Chaplain Schmitt Island (map number 19061CO244F, August 19, 2013). FEMA produces FIRMS that show areas that are at risk to flooding, also known as floodplains or Special Flood Hazard Areas (SFHA). Figure 1 and 2 show flood zones, floodplain boundaries, floodways and base flood elevations of the Mississippi River. Communities use these maps to set minimum building and land development requirements for projects in flood prone areas. Given that potential future development improvement projects at the island will need to comply with local, state and federal floodplain management regulations, it is important to gain an understanding of the various flood zones that are present at the island. 1 2 3 4 5 E610 8 9 A g !04 SCHMITT ISLAND I Development Plan of 1050 Floodplain Special Flood Hazard Areas Special Flood Hazard Areas (SFHA) are defined as areas that are subject to inundation by the one percent annual chance flood or 100-year flood event. Review of the floodplain mapping at the island indicates presence of SFHAs that cover much of Miller Riverview Park, including the Vietnam Memorial, Riverview Park Drive, the campground and the playground and picnic area at the northern tip of the island. SFHAs also cover northwestern portions of the island including the Dubuque Water Sports Club and Heron Pond. SFHAs also are shown to cover the western portion of the west parking lot of the casino and the eastern portion of the east parking lot of the casino. None of the existing casino buildings are currently located within a mapped SFHA. However, SFHAs do appear to encroach onto some of the existing kennel structures and the northwest wing of the Hilton Garden Inn building. The 500-year floodplain (0.2 percent) also covers the majority of the Hilton Garden Inn building and all of the existing kennel buildings. On the south half of the island, mapped SFHAs cover much of the existing marina, including Catfish Charlie's Restaurant, the marine maintenance building, the marina parking lots, the campground and most of Marina Drive. The existing Mystique Community Ice Center, while not located within a SFHA, is mapped within the 0.2 percent or 500-year floodplain. Floodway The floodway is defined as the channel of a waterway plus any adjacent floodplain areas that must be kept free of encroachment so that the one percent annual chance flood (100- year flood event) can be carried without substantial increases in flood heights. Figure 1 is the FEMA regulatory map panel showing the Mississippi River floodway with a diagonal cross hatching pattern. Figure 2 similarly shows the Mississippi River floodway with a light blue color shading. Both maps indicate that the floodway occupies portions of the easterly edge of the island. The floodway on the east end of the island varies in width from approximately 470 feet at the north end of the island, approximately 250 feet at the USH 61/151 bridge, and up to 700 feet wide near the south end of the island. 1 2 3 4 5 E610 8 9 A g ! 120'` SCHMITT ISLAND I Development Plan Page 609 of 1050 Floodplain Base Flood Elevations (BFEs) and Flood Depths The BFE at a particular location is defined as the elevation of surface water resulting from a flood event that has a one percent chance of equaling or exceeding that level in any given year (commonly referred to as the 100-year BFE). The BFEs for the Mississippi River at the island are both depicted on the FIRM floodplain map and also are provided on flood profile exhibits within the city's FEMA Flood Insurance Study (FIS) report. Reviewing these data sources, we see that the 100-year event BFE at the island is 611.0 (North American Vertical Datum of 1988). Figure 3 depicts the estimated depths of flooding for a 100-year flood event (BFE = 611.0). Note that the basis of the ground surface topographic data is available high -resolution light detection and ranging (Lidar) that was obtained and published by the United States Geological Survey (USGS) in 2019. Figure 3 indicates that the easterly area of the island that is mapped floodway generally has 100-year flood depths that are greater than ten feet. Several areas of the island that are not in the mapped floodway also have flood depths greater than ten feet, including the majority of Miller Riverview Park, the Dubuque Water Sports Club (including Heron Pond) and the eight -acre pond located immediately north of the Mystique Community Ice Center site. Areas on the island that have shallower flood depths (i.e. between zero and four feet) include westerly portions of the casino parking lot, easterly portions of east casino parking lot, an area near the southeast corner of the kennel buildings, portions of Admiral Sheehy Drive located immediately north of the ice center and portions of the south marina area including surrounding parking lots and driveways. 1 2 3 4 5 E610 8 9 A g SCHMITT ISLAND I Development Plan rage 010 of 1050 Floodplain Topographic Survey Collection In order to validate the accuracy and reliability of the USGS 2019 Lidar topographic data, we conducted field topographic surveys at several key locations at the island as follows: • Northeast area designated as regulatory floodway in the location of the proposed observation tower. • East parking lot designated as a SFHA floodplain in the vicinity of the "Backwater Stage" area. • West parking lot and entrance drive area designated as a SFHA floodplain. • South marina area designated as a SFHA floodplain. Figure 4 depicts USGS 2019 Lidar ground surface topographic mapping in a color relief format. Figure 5 includes this same Lidar topographic data overlayed with the individual field surface topographic survey data points from the various areas of the island listed above. Within Appendix A, there is a tabular summary of the 379 field survey points that provides a comparison of the surveyed elevation versus the estimated Lidar elevation at the same location. Note that Lidar data is a based on a grid size of one square meter. Comparison of the survey data versus the Lidar data indicates that the elevation differential between the field surveyed shots and the Lidar data falls mainly between plus or minus 0.25 feet (refer to the histogram that is included as an inset exhibit on Figure 5). 92 percent of the field survey shots fall between plus or minus 0.25 feet of the Lidar elevation. Review of the data indicates that the elevation differential does not appear to be skewed either up or down, which seems to indicate that there is not a transformational vertical datum issue. Note that the only area where there appears to be elevation differentials that are more significant (i.e. greater than 1.5 feet) are shots that were taken along the northeast shoreline of the island near the proposed observation tower. There appears to be a logical explanation for this, given that when the Lidar data was collected, it is likely that the Mississippi River levels may have been elevated and the true ground surface elevation was therefore, not represented accurately. Based on the results of the comparison of the field surveyed surface topographic data and the USGS 2019 Lidar topographic data, the Lidar topography appears to be reasonably accurate and is suitable for use for planning level engineering analyses, including the floodplain development assessment described later. 1 2 3 4 5 E610 8 9 A g !04 SCHMITT ISLAND I Development Plan Page 611 of 1050 Floodplain Floodplain and Floodway Regulation Review The City of Dubuque floodplain management regulations are stated within Title 16 Unified Development Code, Chapter 6 Overlay Districts, Section 16-6-4: Flood Hazard Overlay District. The provisions outlined in Section 16-6-4 apply to all lands within the jurisdiction of the City of Dubuque shown on the Official Floodplain Zoning Map as being within the boundaries of the Floodway, Floodway Fringe (Flood Fringe), and General Floodplain (Overlay) Districts. Each of these floodplain districts is described in further detail below. Floodway (Overlay) District (FW). Those areas identified as floodway on the Official Floodplain Zoning Map. These areas are depicted as Zone AE floodplain with diagonal hatched areas on Figure 1 and light blue shaded areas on Figure 2. If development plans include placement of any structures or fill within these areas, engineering analyses will need to be conducted to reflect the effects of this devel- opment on Mississippi River flood levels and to show that no increase in 100-year base flood elevation will result. The following section shares potential development scenarios that could occur within regulatory floodway at the island and the resultant impacts to Mis- sissippi River 100-year base flood elevations. Floodway Fringe (Overlay) Dis- trict (FF). Those areas identified as Zone AE on the Official Flood - plain Zoning Map and exclude those areas identified as floodway. These areas are depicted as Zone AE floodplain with no diagonal hatched area on Figure I and as indigo shaded blue areas on Figure General Floodplain Overlay Dis- trict (FP). Those areas shown with- in the approximate 100-year flood boundary or Zone A on the official floodplain zoning map. Note that there are no General Floodplain Overlay Districts within the limits of Chaplain Schmitt Island. Regardless, any proposed buildings (residential or non-residential) within a SFHA (both floodway and flood fringe areas), must be elevated to be equal to or greater than the flood protection elevation. The flood protection elevation is defined as the regional 100-year storm base flood elevation plus one foot of freeboard. Therefore, the flood protection elevation at the island is equivalent to elevation 612.0. 1 2 3 4 5 E610 8 9 A g SCHMITT ISLAND I Development Plan Page 612 of 1050 Floodplain Floodplain Development Assessment FEMA Effective Hydraulic Model In order to assess the various potential improvement projects at the island, planners requested and obtained the regulatory FEMA hydraulic floodplain model for the Mississippi River from the FEMA Engineering Library. This HEC-RAS hydraulic model simulates the flood water surface elevations of the Mississippi River during a 100-year return interval flood event. Review of this hydraulic model indicated that three Mississippi River stream cross sections pass through portions of the island. A comparison of topographic data from the hydraulic model cross sections indicates that, generally speaking, the ground surface data represented in the model was reasonably close to ground surface data obtained from the USGS 2019 Lidar data. However, for areas that appeared to show some discrepancies, the three river cross sections were adjusted to reflect the Lidar ground surface data on the island. After making these model cross section adjustments, additional intermediate river cross sections were created in the hydraulic model at an approximate interval of just under 200 feet. It is important to note that the Mississippi River hydraulic model only represents flood flows passing through the regulatory floodway as being effective flood conveyance. Flows passing through areas of the island that are outside the floodway boundary (flood fringe areas) are not represented as effective flood conveyance. Graphic exhibits are included within Appendix B which depict the Mississippi River hydraulic model cross section locations. Subsequent graphic exhibits in Appendix B represent each of the three development scenarios discussed below. Floodway Encroachment Analysis The scenarios described below are presented for planning and concept purposes. Specific improvement recommendations will be reviewed during the preliminary and final design phases, along with consideration of permitting issues and relative value. Scenario 1: Fill Entire Floodway Along the East Side of the Island This scenario is a highly conservative "worst- case" scenario in which fill would theoretically be placed within all areas of the island that are mapped as regulatory floodway. The current projects being considered in the master plan (boardwalk trails and the observation tower near the north tip of the island) would certainly involve significantly less potential for obstruc- tion of Mississippi River flood flows. However, the if the outcome of this worst -case scenario option indicates no increases in 100-year Mississippi River base flood elevation, it is reason- able to assume that any development project that is contemplated within the mapped floodway on the island would be permissible from a floodway regulation compliance standpoint. The results of Scenario 1 did indicate some minor base flood elevation increases (approximately 0.04 feet) throughout the stretch of the Mississippi River along the island and points immediately upstream. While these increases seem negligible, the federal, state and local floodway development rules clearly state that no increases in 100-year base flood elevation are to be allowed. Scenario 2: Fill Entire Floodway Up- stream of USH 61/151 This second floodplain development scenario includes theoretically placing fill within all areas of the island that are mapped as regulatory floodway, but only those locations on the island located north of the US 61/151 bridge. This scenario would essentially keep the regulatory floodway areas that are located to the south of the US 61/151 bridge undisturbed. The results of this hydraulic modeling evaluation indicate that the Mississippi River 100- year flood stage would only increase by approximately 0.005 feet. Given that conservative assumptions are still being made for placement of fill that would entirely occupy the floodway north of the US 61/151, it is reasonable 1 2J L 3 4 5 6 67-1 8 9 A g _;04 SCHMITT ISLAND I Development Plan to assume that the projects currently being considered in this part of the island would have little to no impact on Mississippi River flood stage. Scenario 3: Fill Entire Floodway Up- stream of USH 61/151 and Perform Minor Regrading South of USH 61/151 to Offset Minor River Flood Elevation Increases The third floodplain development scenario is generally identical to Scenario 2. However, in an effort to offset the minor Mississippi River flood stage increases resulting from Scenario 2, this model reflects some regrading of floodway areas on the island located south of the US 61/151 bridge. This potential regrading would seek to lower ground surface elevations in this area to near elevation 596. The Scenario 3 hydraulic modeling results indicate that no increases in Mississippi River flood stage would occur. Other Floodplain Development Considerations Given that construction within floodway zones is highly restrictive from a regulatory standpoint, it is important to determine what can and can't feasibly be done in these areas. The results of the floodway encroachment analyses summarized in the previous section demonstrate that locating potential projects in the mapped floodway at the island appears to be feasible. However, development projects on other portions of the island also need to be evaluated. As stated in the regulatory review section, proposed buildings must be elevated to be equal to or greater than the flood protection elevation, which is equivalent to the regional 100-year base flood elevation plus one foot of freeboard (elevation 612.0). This is the minimum flood protection elevation standard that must be met. However, given that storm and flood events are growing in severity and frequency due to the effects of climate change and other threats, consideration should be given to a flood protection elevation standard that improves resilience of future buildings and projects on the island. The Federal Flood Risk Management Standard establishes a flood standard that helps achieve increased resiliency of future projects against flooding. Currently, the Federal Flood Risk Management Standard applies only to federally funded actions involving new construction, substantial improvement or repairs to substantial flood damage. It also applies to hazard mitigation projects involving structure elevation, dry floodproofing and mitigation reconstruction. If federal funding is sought for future development and improvement projects on the island, applying the Federal Flood Risk Management Standard should be considered. If the Freeboard Value Approach (FVA) is applied, it would involve adding two feet to the base flood elevation for non -critical actions and adding an additional three feet to base flood elevation for critical actions. An alternative is increasing the flood protection elevation to the 500-year base flood elevation, which in this case would be approximately 1.5 feet. Increasing the flood protection elevations for new buildings will result in greater cost to account for placement of additional fill to elevate structures beyond the minimum flood protection elevation standard. The increase in resiliency and mitigation of potential future flood risks will need to be balanced with the estimated increases in construction costs to comply with the more stringent flood protection standards. Development Plan I SCHMITT ISLAND , 129` Page 613 of 1050 SCHMITT ISLAND Infrastructure &Analysis Utilities The planning and design team interviewed city staff in the water department, sanitary waste division and civil engineering departments to understand potential issues or opportunities from a utility perspective. These conversations helped provide a high level overview of the key items that should be considered as development moves forward.

The collection system drains to a lift station located near E.16th Street and Admiral Sheehy Drive. While the original planning assumption was that the system would need the capacity to serve high -density residential land use across the entire island, that assumption is no longer in place. Still, any sewer improvements on the island should be based on the highest and best potential land uses, to ensure new system improvements have proper capacity. While there are no immediate issues to be addressed and no glaring shortfalls, the following actions are still recommended: • Verify capacity of the lift station to serve land uses required by future development. • Use flow meters to check the potential risk of flood waters being pushed into the sanitary sewer system via the bolted - down manhole located under the drainage pond that receives geothermal water discharges.

Some of the site drains to a long, narrow pond southeast of Greyhound Park Road under the Wisconsin Bridge. The discharge from the casino and hotel geothermal system also drains to this pond. The pond has no direct surface outlet. City of Dubuque stormwater management regulations require that the peak flow rate leaving new construction and redevelopment sites not exceed the existing peak flow rate expected to be generated by the 2-,10- and 100-year storm events. While there are no immediate pressing stormwater system needs in terms of the regulatory environment, the development plan for Chaplain Schmitt Island includes a strong natural resources component and would do well to include good management and stewardship of water resources. To that end, these projects are recommended: • Design pipe outfalls that will prevent erosion near the outlet and along downstream channels resulting from new construction and/or redevelopment. • Aesthetic and water quality improvements to the pond southeast of Greyhound Park Road under the Wisconsin Bridge. • Add practices that improve the quality of stormwater runoff, using the Iowa Stormwater Management Manual to select, size and design such practices.

The island's water supply comes through a 12" water main connection along the E.16th Street bridge. To ensure a sound, fully functioning system, a backup/redundant supply of water that does circumnavigate the island is needed, allowing repairs anywhere on the island to have access to water. Improvements to the water supply and distribution system on the island would reduce the potential for service disruptions to individual facilities and to the island as a whole Recommended projects include the following: A second connection point to the city water system, potentially by connecting to a future pedestrian bridge that would span across the Peosta channel of the Mississippi River. The connection could be made near the intersection of Hamilton and Kilgore Streets on the opposite side of the river. • Potential improvements to provide adequately sized water mains along Hamilton Street to connect to the 24" water main along Kerper Boulevard. • Additional water valves and new water mains along Greyhound Park Road to provide redundant service connections to the hotel and casino site. • A looped water main connection along Chaplain Schmitt Drive. All new water main installations on the island will need water main materials with nitrite gaskets due to past landfill use at this site, consistent with Iowa Department of Natural Resources (IDNR) requirements.

These projects — and their associated costs — have been prioritized through an analysis of the following considerations. Prioritization Factors 1. Plan Objectives. Does the project help achieve the Development Objectives and the City of Dubuque's Council Priorities? 2. Highest and Best Use. Are the projects financially feasible? Will the project help move the needle and improve the island's appeal for private sector investments? Will the citizens of Dubuque benefit from increased tax or lease revenue? 3. Readiness. Is the project "shovel ready" or can it get there quickly? What steps have taken place to advance the project's standing? 4. Construction Cost. if the magnitude of the project requires capital that is not readily available, alternative funding streams (e.g. grants, sponsorship) may be a factor in the project's short term feasibility. 5. Sequence. Is the project — or is a higher priority project - contingent on infrastructure investments that must occur first to enhance the island's appeal for further development? Does the project "complete" a multi phased project? 6. Ecological, Beautification. Does the project help advance the island's appeal from a habitat or beatification standpoint? 7. Quality of life, Destination Appeal. Will the project appeal to Dubuque citizens, their families and professionals? Will people travel to spend the day on the island, if the project is constructed? Regulation & Policy Considerations In addition to the prioritization considerations, several city policies impacting the island's appeal for development have been uncovered. A brief explanation has been included below. In 2017, residential development was eliminated as an allowable use within the Planned Unit Development Ordinance that governs the island. After an evaluation of the current market conditions in 2024, there is an opportunity for waterfront living on the island. Considerations were also given to large scale destination retail (e.g. bass pro shops), office (in the short term, office demand is very limited) and industrial (deemed an inappropriate use, given the island's vision and land uses) within the island's development framework, but were ruled out as viable alternatives. Given this, a recommendation of this plan is to update the PUD to include multifamily residential. Secondly, given the construction complexities of building on the island, along with market conditions related to residential development, an analysis of a fee simple vs. land lease scenario was evaluated (see sections 3 &4). Given the island's waterfront location, the city has had a longstanding position of being only buyers of riverfront land (as opposed to sellers). While some developers may philosophically not want to lease lands for multifamily residential development, there are some developers who see leasing as a benefit to their business model as it moves the cost to the operational side of the balance sheet. The challenge with land lease in large part then comes down to time. Given the island's physical characteristics and development history, capital costs are anticipated to be slightly higher than a traditional redevelopment situation in downtown Dubuque, for example. This creates a need to re-evaluate the lease terms. This plan's recommendation is for the City to reconsider land leases that have historically been on a 25 year basis to a 75 year basis, but only for high quality development that meets the 1 2J L 3 4 5 6 7 E8Tw A g _;04 SCHMITT ISLAND Development Plan intent of the Island's design guidelines, while simultaneously protecting the investments of those who have developed or will develop in the future. Lastly, In the 1980's, the City received funds for the acquisition and construction of Gerald "Red" McAleece Park through the federal government's Land and Water Conservation Program. With these funds, a land use restriction was enacted by the Department of Interior and provided by the City, limiting use to "outdoor recreation" Removing this restriction is possible and is based on replacing the outdoor recreation uses elsewhere in the city at the present day appraised value. It does not require a sport for sport replacement. Considering this, as investments are made in Schmitt Island, it is reasonable to assume that the site's value — and appraised value — will go up. Given this, this plan recommends that the city collaborate with the Federal Government to remove the restriction on Gerald "Red" McAleece Park. Action Plan Considering the factors above, the following items have been identified as the highest priority actions: 1. Update the PUD Ordinance to allow multifamily residential. 2. Proceed with developing a value matrix for determining when a seventy -five-year vs. a twenty five year land lease is warranted. 3. Proceed with the initial steps of seeking an appraisal for the ballfield site and removing the restriction over Gerald "Red" McAleece Park. 4. Work with the City of Dubuque to issue an RFI to prospective developers to gauge their interest in redeveloping the island south of Highway 151. S. Begin the initial geotechnical and environmental investigation within the existing marina and RV Park on the south side of the island. 6. Conduct a feasibility study to determine the appropriate sports program for the Gerald "Red" McAleece Park and Ice Center.

The island began life as an airport during WWII and was then used as a dump through the 1970s. Beginning in the 1980s, it became the city's catch-all for a great variety of uses and activities, including recreation, gaming, and remembrance.

Executive Summary Master Plan: Three Areas This Plan recommends three different areas on Chaplain Schmitt Island, each with its own characteristics and uses. Within the Lake Peosta Recreational Channel, the wooded, natural feel of the inner channel and Miller Riverview Park will be maintained and enhanced. Opportunities to explore the woods and the water are expanded with hiking paths, habitat islands, a new boathouse and fishing piers. The Casino will be expanded with meeting and ball rooms, hotel, restaurants, and spa, creating a destination resort and event center. The building and landscape will reach out toward and embrace the river and the adjacent wetlands, integrating itself with the island environment. Along the southern tip of the island, retail, housing, and recreation are mixed together to create a walkable, vibrant Island Destination. The open river views along the river walk create a friendly space where people will meet, eat, and play.

Site Context & Analysis Page 638 of 1050 2. Site Context & Analysis Site Context Regional Context Dubuque is located on the Iowa side of the Mississippi River, across from the Illinois and Wisconsin border and almost halfway between Cedar Rapids, Iowa, and Madison, Wisconsin. The U.S. Highway system links Dubuque to these regional destinations. Dubuque's Regional Setting: Dubuque is located approximately halfway between Madison, Wisconsin, and Cedar Rapids, Iowa (left, top). Dubuque is located on the Mississippi River within the Driftless Region (left, bottom). Schmitt Island is Dubuque's only island in the Mississippi River (right, bottom) downtown accommodates four U.S. highways, including one that passes through and bisects Schmitt Island. Dubuque is found within the Driftless Region, a 16,000 square mile area untouched by glaciers in the last glacial period. This scenic landscape is characterized by steep river bluffs and deep valleys, attracting regional tourists interested in hiking, biking, fishing, and other recreational activities. Mississippi River The Mississippi River and the blufliands are Dubuque's most prominent natural features. Each reinforces the sense of place that distinguishes Dubuque and each has contributed to the area's visual, recreational, commercial, and community appeal throughout the years. Dubuque's bluffs give added topographical definition and identity to the city. They rise 300 feet in less than a mile, with some reaching 900 feet above sea level. The Mississippi River is valued not only for its scenic beauty, richness of habitat, and recreational opportunities, but also for its role in the region's commercial and industrial success. The riverfront is home to both cultural and industrial activity, and serves as part of a major migratory flyway. Schmitt Island is Dubuque's only island in the Mississippi River; therefore, what happens in the District should highlight this unique attribute. Page 639 of 1050 2. Site Context & Analysis Site Context (continued) City Investment After the record high unemployment rate of the early 1980s, the City of Dubuque worked to diversify their economy and came back in 2005 to be named one of the fastest -growing cities in the Midwest. In the last few years, the City has been building upon this success by investing in award -winning development and revitalization projects along the riverfront. Projects such as the Bee Branch Creek Restoration and the Washington Neighborhood Green Alley program has put Dubuque on the map as a model city for sustainability. New development projects such as the The Port of Dubuque Bee Branch Creek Restoration Millwork District Historic Millwork District and the Port of Dubuque show a strong dedication to reinvesting in under- performing sites and bringing increased population and revenue to the city.7hese and other upcoming projects point toward continued progress and provide an exciting context for the future of Chaplain Schmitt Island. Not only do these investments build upon each other and share momentum, they can also be physically connected with public infrastructure, ultimately creating a walkable riverfront environment worthy of the "Masterpiece on the Mississippi".

Site Context & Analysis Site Analysis (continued) River Channels & Siltation Chaplain Schmitt Island is flanked by two interconnected but characteristically and behaviorly different channels of the Mississippi River. The channel to its east is the river's main path and is maintained by the US Army Corps of Engineers as a commercial shipping corridor. Wide and fast -flowing, it is flanked by a high bluff. Lake Peosta Channel to the west, by contrast, is a former backwater that was widened to allow river access to adjacent industrial land. The water here is relatively narrow and calm. Island forming off Chaplain Schmitt Island I vvu Iv 11JJIJJIppi III — —la1II1 13 the waters of the Mississippi River carry a great deal of sand and silt, which can collect over time. The Army Corps dredges (removes) this material in the shipping channel, but along the edges of both channels, especially in Lake Peosta Channel, islands and sandbars are forming. This siltation can have both positive and negative impacts on ecological habitat and recreational access. Lake Peosta Channel Calm, manmade backwater. Main Channel Large shipping channel. CUNINGHAM G R O U P Page 645 of 1050 2. Site Context & Analysis Site Analysis (continued) Flooding Much of Dubuque is protected from river flooding by levees but Chaplain Schmitt Island is outside of the leveed area, meaning that it is subject to the river's "bounce", or the up and down movement of water levels throughout the year. Historically the island has flooded only in spring, but more frequent (2-3 times/year) and longer flood events are being reported for the area. Federally -backed flood insurance is made available by FEMA in communities that agree to regulate development in their 100-year floodplain. According to these regulations, new buildings must have finished floor elevations a minimum of one foot above the 100-year flood level, though communities may want to consider building higher than this, given the changing nature of the Mississippi River.'Ihe eastern edge of the island is located within the regulated floodway. Development here must be regulated to ensure that there are no increases in upstream flood elevations. Levees & Leveed Areas Much of Dubuque is protected from river flooding by levees, while Chaplain Schmitt Island is not. Flood Event 2011 aerial photograph of a flood event on island. Flood Levels Shown here is the record high water level on the island (set in 1965 & 2001) and the 100-year flood level, which both happen to be around the same elevation (612 mean sea level). CUNINGHAM G R O U P Page 646 of 1050 2. Site Context & Analysis Site Analysis (continued) Protected Natural Resources Chaplain Schmitt Island is part of the much larger natural system of the Upper Mississippi River Valley, portions of which are reserved and managed by the US Fish & Wildlife Service as refuge areas for birds, fish, plants, and other wildlife. While the island itself is not protected as part of this refizge system, certain areas or habitats may be protected. For example, the lower portion of Lake Peosta Channel is home to a large mussel bed that includes an endangered species called Higgins' Eye mussels. Similarly some of the wetlands that line much of the island edges may be protected as well. For example, much of the north end of island is a wetland that was mitigated, meaning that it is protected and likely cannot be modified. Before moving forward with any projects that may impact possible protected habitats on Chaplain Schmitt Island, the City of Dubuque will have to work closely with regulating agencies.

Character Areas the wide variety of land uses and landscape types on Chaplain Schmitt Island lends different characteristics to various parts of the island. This Plan builds off these existing characteristics to define three different Character Areas, each of which has its own land use pattern, relationship with the river, range of building types, circulation needs, and open space. Each Character Area will evolve differently over time and at different rates. Defining the Character Areas helps promote orderly and predictable development. Lake Peosta Recreational Channel The wooded, natural feel of the inner channel and Miller Riverview Park will be maintained and enhanced. Opportunities to explore the woods and the water are expanded with hiking paths, habitat islands, a new boathouse and fishing piers. Island Resort The Casino will be expanded with meeting and ball rooms, hotel, restaurants, and spa, creating a destination resort and event center. The building and landscape will reach out toward and embrace the river and the adjacent wetlands, integrating itself with the island environment. Lake Peon Recreatior Channel Marina Village Island Destination Along the southern tip of the island, retail, housing, and recreation are mixed together to create the walkable, vibrant destination. The open river views along the promenade create a friendly space where people will meet, eat, live and play. CUNINGHAM G R O U P Page 653 of 1050 3. Goals & Frameworks Frameworks (continued) 2.Open/Public Space Go -to A "go -to" space is a place you can point to on a map or tell someone to meet you. It is a defined space to stop, gather, or enjoy a view. It could take the form of a building or designed outdoor space, such as a plaza or an amphitheater. M%M Go -through "Go -through" spaces are places you walk along or move through. It likely takes the form of walkway or paved trail (solid lines) or boardwalk (dashed lines). It is a place to run, walk, or bike. Natural areas Natural areas are park -like spaces or habitat areas. On Chaplain Schmitt Island, they are likely wooded. Here one can bird - watch, learn about plants and animals, or watch the river through the trees.

Goals & Frameworks Frameworks (continued) 3. Circulation Overall this Plan simplifies circulation for vehicles and increases access for pedestrians and bicycles. A new traffic circle (roundabout) clears congestion during events on the island and slows traffic exiting off highway ramps. A new road alignment along the marina gives public access to the riverfront and increases visibility for existing and future businesses. Bike lanes on streets increases safety and allows more access and options for bikers. A public riverwalk gives complete pedestrian access along the riverfront in the marina area. Boardwalk paths in the wetlands allow pedestrians to experience the natural beauty of wooded wetlands - even when island is flooded - but limits potential negative impacts on wildlife. A pedestrian/bike bridge across the Peosta Channel creates a looped trail that connects to the existing trail on the mainland. Existing Circulation 26 CUNINGHAM G R O U P Page 655 of 1050 3. Goals & Frameworks Frameworks (continued) 4. Development Types Development types on Chaplain Schmitt Island will respond to the frequent flooding levels. The center portion of the island (1) is above the record flood elevation. Buildings situated in this area can be basic slab on grade because they are not as likely to experience flooding. The western edge of the island (2) experiences frequent flooding but is not in the floodway. Buildings here can be raised up on stilts or by grade, allowing the buildings to still be used in times of flooding. The eastern edge (3) is wholly within the floodway, greatly limiting what can be constructed or modified. 1.Out of Flood Plain - Slab on grade 2. Raised Above Flood - Building floor level brought up above the record flood elevation, either by raising the grade or raising the building on stilts. 3. In Flood Plain - Anything constructed must be able to weather flood waters. Most likely no permanent buildings. 2 Three Development Types in Section 1.Out of Flood Plain --------------------------------------eta+_ ---------------------------------------611 — — — — — — — — — — — — — — — — — — — — — — — — — — — — — — 601 — 600 2.

The purpose of defining these Character Areas is to guide changes and investments on the island as they come forth over the upcoming decades. With channel improvements and increased access to the waterfront, the western edge of the Island will become a water -based recreational area. Casino expansion and improved campgrounds and trails through the wetlands will allow the northern portion of the Island to become a unique island resort. The southern half of the island will develop as an Island Destination with new retail, restaurants, entertainment, and recreational amenities.

The Casino supports dozens of reinvent itself to remain competitive. In the future, organizations in Dubuque and contributes significantly revenue growth will rely less on gaming than it will to the City's tax base. The economic landscape for on entertainment, lodging, special events, retail, and Mystique Casino is changing: restaurants. With new gaming options in Illinois and Wisconsin, Mystique is losing customers that travel from beyond 60 miles of Dubuque. They are opting for closer options in Madison or video gaming in Illinois. Diamond Jo Casino opened at the Port of Dubuque in 2008. While Mystique has remained competitive, Diamond Jo is newer and has different entertainment options that draw a younger crowd. The operations of Greyhound Racing at Mystique will be transferred to the Iowa Greyhound Association via a five year lease at 1$/yr. with an option to extend the lease at a prevailing market lease. Miller Riverview Park Mystique Casino Dog Racing Track Miller Riverview Park Miller Riverview Park is a beloved park consisting of a campground, mitigated wetlands, and the Tri State Vietnam Memorial. Much of the eastern edge of the park is in the floodway and floodplain. As a result access to the campground is restricted when the river levels are high in the spring and early summer. The wetlands in Miller Riverview Park are mitigated wetlands, created in 1987 as a part of a project at Kerper Blvd and 19th Street. They consist of a variety of different habitats, wetlands, and open water. Per the Vietnam Veterans Memorial M CUNINGHAM G R O U P Page 661 of 1050 3. Master Plan Island Resort (continued) City's agreement with the Iowa Department of Natural Resources and the Army Corps, adjustments to these wetlands would require extensive coordination and likely additional mitigation. The east edge of the Park is regulated as part of the Mississippi River Floodway. Generally, disturbances and development in the floodway is prohibited if it has any impact on upstream flood elevations. In addition, any structure that would impede the flow of river debris is prohibited. Veterans Memorial The Vietnam Veterans Memorial was established to honor Veterans of the Vietnam War from Iowa, Wisconsin, and Illinois. The memorial is above flood levels, but it is located behind the gates to Miller Riverview Park, which is occasionally closed.

Master Plan Island Resort (continued) First Phase Initial investments on the Casino Property assumes no change to the Greyhound Racing operations for at least five years. The Plan recommends initial expansion to occur on the eastern portion of the property, replacing the secondary parking lot with an event center (35,000 sf), parking structure (400 cars), and amphitheater (seating for 2,000). In addition, early investments can include improvements to the parking lot to include tree trenches, which filter and store stormwater underground. Access to the park and its wetlands should be improved in the First Phase. Low impact paths and trails through the wetlands can provide access to natural areas and improved connectivity throughout the entire island. Improving access to the wetlands will provide an opportunity for visitors to the Casino to experience the environment of the Island. Consideration should be given to diversifying the camping options at Miller Riverview Park to include larger campers. r "qqwi' Hotel expansion I � s i ~ Improved Parking Lot in Veterans Memorial _ �♦ Parking � ti ue Casi o structure expansion � Outdo amphith er Event i Center First Phase Expansion: Initial Casino property improvements can include an amphitheater, parking structure, Event Center, and an improved parking lot.

Master Plan Lake Peosta Recreational Channel Existing Conditions The Peosta Channel is a man-made channel, created in 1930s when the area was dredged to create industrial land adjacent to Kerper Boulevard. The Peosta Channel is considered a back channel and not needed for river navigation and therefore it is not maintained and dredged by the Army Corps. Since it is relatively calm and safe water, the channel is used by boaters and anglers. The Dubuque Water Sports Club has a lease for a portion of the rivers edge (on the Island) that they use for launching, staging and events watching. The Water Sports Club represent a range of boaters and water enthusiasts, including dragon boaters, water skiers, rowers, kayakers, and canoeists. The low bridge on the south end of the channel restricts large boats from using the channel. Levee Developing islands Peosta Channel A" Mystique Casino CUNINGHAM G R O U P Page 667 of 1050 3. Master Plan Lake Peosta Recreational Channel the eastern edge of the channel is lined with wetlands; the west edge of the channel is lined with a levee. A trail runs along the top of the levee; however there is no access to the water from the levee. In recent years, the channel has been silting up, creating sandbars and islands that have further restricted larger boats from using the channel. Higgins Eye Mussels, an endangered species, are likely located at the southern edge of the channel. there is a known mussel bed in the main channel across from the island. Their habitat requires relatively deep water with moderate currents. Adjustments to the channel must protect their habitat. Dock on Peosta Channel Peosta Channel Recommendations The Plan recommends the western edge of the Island and the Peosta Channel become a water -based recreation area. In order to accomplish this, investments have to be made to create a stable and calm water environment for boating and swimming. the Plan recommends dredging the channel to an appropriate depth and using the dredge materials to create stable islands on the northern portion of the channel. Islands will help balance the hydrology of the channel ensuring that Mussel habitat is protected while at the same time providing stable and relatively calm (but not still) water in the channel for recreational use. Water Sports Club Lease area Trail Page 668 of 1050 3. Master Plan Lake Peosta Recreational Channel New islands located on the north side of the channel will create a calm boating environment for paddlers and other small boats. The new islands can be engineered for stability thereby reducing the need to dredge in the future. The south side of the channel can be maintained as open water, suitable for water skiing, rowing, and paddling races and other recreational uses. A new boat house can be located along the shoreline of the open water, more easily visible from the highway bridge.

The Boathouse can be used to stage events, store boats, and provide amenities to the general public such a boat rentals. Ped/bike bridge Kayaking around islands Boathouse Beach A public trail, fishing pier, and beach should be located along the western edge of the island to create multiple access points to the water and viewing areas. A new pedestrian bridge, located between the open water and the new islands, will increase access to all parts of the islands from the mainland. The bridge would connect into the local and regional bike trails, allowing pedestrians and bicyclists a safe and convenient way to access the Island.

Master Plan Island Destination Existing Conditions The southern side of Chaplain Schmitt Island currently contains a series of uses with minimal relationship to each other. American Marine leases the two harbors (Bissell and Schmitt) and adjacent properties. In addition to boat sales and servicing, their property is used for camping, storage, and Catfish Charlie's restaurant. Their lease ends in 2031. The McAleece Park and Recreation Complex consists of three softball fields, one regulation baseball field, concession stands, playground equipment, picnic tables, a skate park, and BMX biking. The complex was built in 2005 with (Section 6f) Land and Water Conservation Funds. The Mystique Community Ice Center was built in 2010. It is owned by the City of Dubuque and managed by the Dubuque Community Ice and Recreation Center (DICE). The Ice Center is home to the Dubuque Fighting Saints. The Ice Center was built with the capacity to expand to a second ice sheet, but there are no plans to do so. Mystique Community Ice Center Veterans Memorial Veterans Memorial Plaza is located north of the Ice Center and adjacent to a wetland pond. The Veterans Memorial Plaza was built in 2009 and contains two memorials (Chaplain Schmitt Memorial and the Veterans Memorial) as well as a displayed Vietnam Era Cobra helicopter. Access to the Island is located on the southern side of the island. The bridge to the main land becomes the highway ramp at an uncontrolled intersection. The intersection poses problems because high speed traffic makes it dangerous to cross in the north -south direction. In addition, left turns from the northern and southern legs of the intersection are permitted but not encouraged. 1 - -a r Chaplain Schmitt Memorial Catfish Charlie's at American Marine Boat Launch CUNINGHAM G R O U P Page 674 of 1050 3.

Master Plan Island Destination (continued) Recommended Infrastructure Improvements The Plan recommends the City work closely with the Iowa Department of Transportation (IA DOT) to enhance and rebuild the Island's main intersection to improve access to the Island's main loop road. A roundabout or a traffic signal are two options that would slow the east -west traffic thereby allowing improved access to the Island's loop road. The elevation of this intersection and the legs leading up to it should be raised to 612' - in keeping with the rest of the loop road around the Island. Raising the loop road to 612' would ensure emergency access to the Island in high water events. The southern leg of the roundabout (or signal) will be new road located between the Mystique Community Ice Center and American Marine Yacht lease area. This road would connect to Schmitt Harbor, thereby providing additional and improved access and visibility to Catfish Charlie's and the southern most tip of the Island, the Harbor, and the front of the Ice Center. This new road should be built at elevation 612'thereby acting as a levee for the Ice Center and the Memorial Plaza.

Master Plan Island Destination (continued) Veterans Memorial Plaza The Plan recommends enhancing the Veterans Memorial Plaza by improving the edge of the pond with a pathway, shelters, seating, and plaza expansion space for additional memorials and veterans tributes. An improved and expanded Memorial Plaza will facilitate formal and informal gatherings, ceremonies, and contemplation. The Plaza should become part of the overall public space system on the island. M Boat Ramp and Schmitt Harbor Park 'Ihe public boat ramp south of the softball fields are popular and well -used. The Plan recommends keeping the launch in place and enhancing the area to its immediate west as a Schmitt Harbor Park for use by the general public. This park could have a small performance space, boardwalk, and space of unstructured passive uses. The park can also serve as a trail head location for walkers and bikers to access the wetlands on the eastern edge of the Island.

Master Plan Island Destination (continued) Marine Development The Plan recommends transitioning land uses on the American Marine leased land into uses that support a vision of a Island Destination. Currently the uses are water -related but dominated by storage and maintenance uses. The Plan encourages the lease- holder and the City to work together to create the center of an Island Destination on the peninsula and surrounding Schmitt Harbor. An Island Destination should include restaurants and retail on the peninsula with an active marina and public access around the harbor. The western side of the peninsula can also be used for larger excursion boats that may currently use the Port of Dubuque. In recent years the Port of Dubuque has experienced conflicts with boats due to the increasing demand to stop in Dubuque. Redevelopment on the peninsula would be organized along a single loop road that provides access to 3-5 story buildings facing Schmitt Harbor. The entire perimeter of the harbor and peninsula should be a public walkway, with occasional gathering spaces located at critical Bissell Ha Sales din Public boat ramp � C S mitt I bor � Camping & boat storage Marina storage maintenance American Marine Lease Area: The transition to a Marina Village can be incremental, allowing the current operations to consolidate. Schmitt Harbor places - the end of the peninsula, street extensions, and the head of Schmitt Harbor. The American Marine property could redevelop over a series of phases. Initial efforts should be directed towards improving public access to the water on the north edges of Schmitt Harbor, a virtually unused portion of the site. Any storage in this location can be consolidated elsewhere on the property without impacting the current operation of American Marine. In doing so this would Maintenance and Service at American Marine Camping and Dry Land Boat Storage CUNINGHAM G R O U P Page 678 of 1050 3.

Medium -term efforts (5-10 years) should be directed towards consolidating as many current uses as possible to Bissell Harbor, thereby freeing up the peninsula on Schmitt Harbor for retail and marina -related development. the last (beyond 10 years) portion of the American Marina site to be developed should be the northwestern portion surrounding Bissell Harbor. ri� H�� - .r'^ Precedent Images Describing the Type and Scale of Development of the Island Destination B CUNINI G R O Page 679 of 1050 3. Master Plan Island Destination (continued) Mystique Community Ice Center The Mystique Community Ice Center is operated by the Dubuque Community Ice and Recreation Center. The Plan recommends expanding the Ice Center to include additional recreational uses such as indoor soccer or climbing wall. The expansion should be attached to the existing building and should support the waterfront orientation of the existing building. The space in front of the Ice Center can be developed as a public plaza, gathering place, and circulation area for the Center. Parking - Mystique Community Ice Center Marina Village the Plan also recommends eventually locating a public/shared parking ramp adjacent to the Ice Center, on its northern side. 'Ibis ramp would be needed to support additional recreational uses on site as well as events in the Ice Center. Currently events at the Ice Center create a parking demand that exceed what the site itself can supply. With 3,000 seats, the Dubuque Fighting Saints need parking for approximately 1200 cars. There are approximately 125 spaces on site. This amount is sufficient for general All t_• X W terfront Inn recreational use and needs to be maintained into the future. During games, fans park at the softball field complex (548 spaces), on the grass adjacent to the Ice Center (100-200 spaces), by the skate park, and at the Casino. It is important to support events at the Ice Center with adequate parking, access, and egress. As the Island redevelops, efforts should be made to ensure replacement parking is well -located, shared with other uses, and attractive. The Mystique Ice Center should extend its mission as a community recreation facility by expanding to additional year-round uses. Shown is an trampoline park, an example of indoor recreation that can take place in the Ice Center's addition. 51 CUNINGHAM G R O U P Page 680 of 1050 3. Master Plan Island Destination (continued) The Plan recommends a new public parking structure (400 spaces) be located on the eastern side of the existing Ice Center. A structure in this location can replace a portion of the parking currently located on the softball field. It can be attached directly to the Ice Center and support both the Ice Center fixture development onsite and adjacent. The Plan suggests two possible additional locations for ramps to support the Ice Center and development on the Island. One is proposed to be located on the American Marine leased property. This ramp can intercept traffic before it enters the roundabout and would be adjacent to Catfish Charlie's and other new development on Bissell Harbor. If an additional ramp is needed, it should be located coincident with redevelopment of the McAleece Park and Recreation Complex. McAleece Park and Recreation Complex r Illustrative Plan of Island Destination The four ballfields were built in the early 1990s through the Land and Water Conservation funds. They are located on the largest and driest land on the Island. If the ballfields are redeveloped, funds (approximately $110,000) would have to be repaid to the Federal government. In addition, parks built with Section 6(f) funds can only be converted with approval of the Secretary of the Interior. In addition to repaying the grant„ "the Secretary shall approve such conversion only if he finds it to be in accord withthe then existing comprehensive statewide outdoor recreation plan and only upon such conditions as he deems necesarry to assure the substitution of other recreational properties of at least equal fair market value and of reasonably equivalent usefulness and location." Whereas this Plan poses options for redevelopment of the softball fields, it is with the understanding and assumption that new ballfields would have to be built elsewhere in the city before eliminating those on the Island. This Plan offers two potential futures for redevelopment of the 21-acre McAleece Park and M CUNINGHAM G R O U P Page 681 of 1050 3. Master Plan Island Destination (continued) Recreation Complex: • Retail / Commercial Mix • Minor league ballpark Retail Option The first option for redevelopment emphasizes destination retail on the majority of the site. The 21-acre site can accommodate a regional shopping development of 175,000 to 200,000 sf. in addition to 1-2 blocks of entertainment / commercial uses. A retail project on the McAleece Recreation Complex site should be integrated into the rest of the Island's improvements. As with the other two options, the block structure from the Marina Village should extend into the site and the Veterans Memorial Plaza should extend into the front walkway to the retail project. Retail on the site would likely benefit Mystique Casino significantly. As a regional draw, a retail project would pull potential customers to the Island from well outside Dubuque. A visit to a destination retail project could be integrated into a day at the Marina, Casino, or beach. Minor League Ballpark Option A second option for redevelopment of the site is to use it for a Minor League Ballpark. Dubuque has considered supporting a team, if a team was interested in moving to Dubuque. Dubuque has studied a site in the Port of Dubuque in-depth. Whereas there has been some development on the Port of Dubuque, the proposed ballpark site is still available. A ballpark would fit well on the McAleece Recreation Complex site and it would offer a unique environment for watching and attending a game. Visitors would enjoy views of the river and bluffs and could enjoy a day on the Island visiting any of the other destinations this Plan is recommending. A ballpark on the Island would require significant parking investment. The proposed parking ramp at the Mystique Ice Center could be used for the ballpark, but approximately 1600 additional spaces would likely have to be built to support a 6000 seat ballpark. This would likely require two and maybe three additional ramps on the Island. M CUNINGHAM G R O U P Page 682 of 1050 3.

Chaplin Schmitt Island Floodplain Study INTRODUCTION Recent elevated Mississippi River levels in spring 2023 have highlighted the fact that portions of Chaplin Schmitt Island are prone to periodic and prolonged flooding. For this reason, as development planning efforts continue to advance at the island, it will be important to evaluate and understand the impact potential Mississippi River flood risks will have on the feasibility of various improvement projects being considered. This includes confirming compliance with applicable federal, state, and local floodplain and floodway regulations that will govern whether potential improvements at the island are feasible from a regulatory, engineering, and cost perspective. EXISTING FLOODPLAIN MAPPING REVIEW Figures 1 and 2 depict the regulatory Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) for Chaplin Schmitt Island (map number 19061CO244F, August 19, 2013). FEMA produces FIRMs that show areas that are at risk to flooding, also known as floodplains or Special Flood Hazard Areas (SFHA). Figure 1 and 2 show flood zones, floodplain boundaries, floodways, and base flood elevations of the Mississippi River. Communities use the maps to set minimum building and land development requirements for projects in flood prone areas. Given that potential future development improvement projects at the island will need to comply with local, state, and federal floodplain management regulations, it is important to gain an understanding of the various flood zones that are present at the island. A. SFHA SFHAs are defined as areas that are subject to inundation by the 1 percent annual chance flood or 100-year flood event. Review of the floodplain mapping at the island indicates presence of SFHAs that covers much of Miller Riverview Park, including the Vietnam Memorial, Riverview Park Drive, the campground, and the playground and picnic area at the northern tip of the island. SFHAs also cover northwestern portions of the island including the Dubuque Water Sports Club and Heron Pond. SFHAs also are shown to cover the western portion of the west parking lot of the casino and covers the eastern portion of the east parking lot of the casino. None of the existing casino buildings are currently located within a mapped SFHA. However, SFHAs do appear to encroach onto some of the existing kennel structures and the northwest wing of the Hilton Garden Inn building. Also covering the majority of the Hilton Garden Inn building and all of the existing kennel buildings is 0.2 percent or 500-year floodplain. On the south one-half of the island, mapped SFHAs cover much of the existing marina, including Catfish Charlie's restaurant, the marine maintenance building, the marina parking lots, the campground, and most of Marina Drive. The existing Mystique Community Ice Center, while not located within a SFHA, is mapped within the 0.2 percent or 500-year floodplain. B. Floodway The floodway is defined as the channel of a waterway plus any adjacent floodplain areas that must be kept free of encroachment so that the 1 percent annual chance flood (100-year flood event) can be carried without substantial increases in flood heights. Figure 1, which is the FEMA regulatory map panel, shows the Mississippi River floodway with a diagonal cross hatching pattern. Figure 2 similarly shows the Prepared by Strand Associates, Inc.° 1 R:\MAD\Documents\Reports\Archive\2023\RDG Planning & Design, Inc\Chaplin Schmitt Island Floodplain Study. 5164.001.MAJ.Dec\Report\Tech Memo.docx\121823 Page 687 of 1050 Page 688 of 1050 s� Legend FEF1A Floodplain �` `� Fucd�tiay � 100yr Flood Fringe r 500yr I VA N w+E s 0 100 200 400 LIS Feel D' Zq A C o m n ' 5Z 0 J N m vJO a T �1 r--- ' i 74 FEMA FLOODPLAIN MAPPING CHAPLIN SCHMITT ISLAND FLOODPLAIN STUDY DUBUQUE RACING ASSOCIATION DUBUQUE, IOWA Page 689 of 1050 Technical Memorandum RDG Planning & Design, Inc. Chaplin Schmitt Island Floodplain Study Mississippi River floodway with a light blue color shading. Both maps indicate that the floodway occupies portions of the easterly edge of the island. The floodway on the east end of the island varies in width from approximately 470 feet at the north end of the island, approximately 250 feet at the United States Highway (USH) 61/151 bridge, and up to 700 feet wide near the south end of the island. C. Base Flood Elevations (BFEs) and Flood Depths The BFE at a particular location is defined as the elevation of surface water resulting from a flood event that has a 1 percent chance of equaling or exceeding that level in any given year (commonly referred to as the 100-year BFE). The BFEs for the Mississippi River at the island are both depicted on the FIRM floodplain map and also are provided on flood profile exhibits within the City of Dubuque's (City's) FEMA Flood Insurance Study (FIS) report. Review of these data sources indicates that the 100-year event BFE at the island is 611.0 (North American Vertical Datum of 1988). Figure 3 depicts the estimated depths of flooding for a 100-year flood event (BFE=611.0). Note that the basis of the ground surface topographic data is available high -resolution light detection and ranging (Lidar) that was obtained and published by the United States Geological Survey (USGS) in 2019. Review of Figure 3 indicates that the easterly area of the island that is mapped floodway generally has 100-year flood depths that are greater than 10 feet. Areas of the island that are not in mapped floodway that also have flood depths greater than 10 feet include the majority of Miller Riverview Park, the Dubuque Water Sports Club (including Heron Pond), and the 8-acre pond located immediately north of the Mystique Community Ice Center site. Areas on the island that have shallower flood depths (i.e. between 0 and 4 feet) include westerly portions of the casino parking lot, easterly portions of the east casino parking lot, an area near the southeast corner of the kennel buildings, portions of Admiral Sheehy Drive located immediately north of the ice center, and portions of the south marina area including surrounding parking lots and driveways. TOPOGRAPHIC SURVEY DATA COLLECTION In order to validate the accuracy and reliability of the USGS 2019 Lidar topographic data, we conducted field topographic surveys (379 field survey points) at several key locations at the island as follows: ■ Northeast area designated as regulatory floodway in the location of the proposed observation tower. ■ East parking lot designated as a SFHA floodplain in the vicinity of the Backwater Stage area. ■ West parking lot and entrance drive area designated as a SFHA floodplain. ■ South marina area designated as a SFHA floodplain. Figure 4 depicts USGS 2019 Lidar ground surface topographic mapping in a color relief format. Figure 5 includes this same Lidar topographic data overlayed with the individual field surface topographic survey data points from the various areas of the island listed above. Within Appendix A, there is a tabular summary of the 379 field survey points that provides a comparison of the surveyed elevation versus the estimated Lidar elevation at the same location. Note that Lidar data is a based on a grid size of 1 square meter.

Chaplin Schmitt Island Floodplain Study Comparison of the survey data versus the Lidar data indicates that the elevation differential between the field surveyed shots and the Lidar data falls mainly between plus or minus 0.25 feet (refer to the histogram that is included as an inset exhibit on Figure 5). 92 percent of the field survey shots fall between approximately 0.25 feet of the Lidar elevation. Review of the data indicates that the elevation differential does not appear to be skewed either up or down, which seems to indicate that there is not a transformational vertical datum issue. Note that the only area where there appears to be elevation differentials that are more significant (greater than 1.5 feet) are shots that were taken along the northeast shoreline of the island near the proposed observation tower. There appears to be a logical explanation for this, given that when the Lidar data was collected, it is likely that the Mississippi River levels may have been elevated and therefore, the true ground surface elevation was not represented accurately. Based on the results of the comparison of the field surveyed surface topographic data and the USGS 2019 Lidar topographic data, the Lidar topography appears to be reasonably accurate and is suitable for use for planning level engineering analyses, including the floodplain development assessment described later in this technical memorandum. FLOODPLAIN AND FLOODWAY REGULATION REVIEW The City floodplain management regulations are stated within Title 16 Unified Development Code, Chapter 6 Overlay Districts, Section 16-6-4: Flood Hazard Overlay District. The provisions outlined in Section 16-6-4 applies to all lands within the jurisdiction of the City shown on the Official Floodplain Zoning Map as being within the boundaries of the Floodway (FW), Floodway Fringe (Flood Fringe) (FF), and General Floodplain (Overlay) (FP) Districts. Each of these floodplain districts is described in further detail below: LINES", I Those areas identified as floodway on the Official Floodplain Zoning Map. These areas are depicted as Zone AE floodplain with diagonal hatched areas on Figure 1 and light blue shaded areas on Figure 2. If placement of any structures or fill within these areas is considered, engineering analyses will need to be conducted to reflect the effects of this development on Mississippi River flood levels and show that no increase in 100-year base flood elevation results. The following section provides the results of potential development scenarios that could occur within regulatory floodway at the island and the resultant impacts to Mississippi River 100-year base flood elevations.

Chaplin Schmitt Island Floodplain Study C. FP Those areas shown as being within the approximate 100-year flood boundary or Zone A on the official floodplain zoning map. Note that there are no General Floodplain Overlay Districts within the limits of Chaplin Schmitt Island. Regardless, any proposed buildings (residential or non-residential) within a SFHA (both floodway and flood fringe areas), must be elevated to be equal to or greater than the flood protection elevation. The flood protection elevation is defined as the regional 100-year storm base flood elevation plus 1 foot of freeboard. Therefore, the flood protection elevation at the island is equivalent to elevation 612.0. FLOODPLAIN DEVELOPMENT ASSESSMENT A. FEMA Effective Hydraulic Model In order to perform the floodplain development assessments for various potential improvement projects at the island, Strand Associates, Inc.° (Strand) requested and obtained the regulatory FEMA hydraulic floodplain model for the Mississippi River from the FEMA Engineering Library. This HEC-RAS hydraulic model simulates the flood water surface elevations of the Mississippi River during a 100-year return interval flood event. Review of this hydraulic model indicated that three Mississippi River stream cross sections pass through portions of the island. A comparison of the topographic data from the hydraulic model cross sections indicated that generally speaking, the ground surface data represented in the model was reasonably close to ground surface data obtained from the USGS 2019 Lidar data. However, given there are areas where there appeared to be some discrepancies, the three river cross sections were adjusted to reflect the Lidar ground surface data on the island. Following making these model cross section adjustments, additional intermediate river cross sections were created in the hydraulic model at an approximate interval just under 200 feet. It is important to note that the Mississippi River hydraulic model only represents flood flows passing through the regulatory floodway as being effective flood conveyance. Flows passing through areas of the island that are outside the floodway boundary (flood fringe areas) are not represented as effective flood conveyance. Graphic exhibits are included within Appendix B which depict the Mississippi River hydraulic model cross section locations. Subsequent graphic exhibits in Appendix B are also provided which represent each of the development scenarios (Scenarios 1 through 3) that are discussed in the following. B. Floodway Encroachment Analysis Given that Strand is currently at a concept level planning stage, the goal of this initial floodway encroachment analysis is to determine what level and extent of development within the regulatory floodway is feasible. The scenarios that have been evaluated should not be considered actual development proposals, but rather a process of establishing what can and cannot be done in the floodway from a development and regulatory approval perspective. Scenario 1—Fill Entire Floodway Along the East Side of the Island It should be understood that this potential development scenario is a highly conservative "worst -case scenario" where fill would theoretically be placed within all areas of the island that are Prepared by Strand Associates, Inc.° 4 R:\MAD\Documents\Reports\Archive\2023\RDG Planning & Design, Inc\Chaplin Schmitt Island Floodplain Study. 5164.001.MAJ.Dec\Report\Tech Memo.docx\121823 Page 695 of 1050 Technical Memorandum RDG Planning & Design, Inc. Chaplin Schmitt Island Floodplain Study mapped as regulatory floodway. Note that the current projects being considered in the master plan (boardwalk trails and the observation tower near the north tip of the island) would certainly involve significantly less potential for obstruction of Mississippi River flood flows. However, if the outcome of this worst -case scenario indicates no increases in 100-year Mississippi River base flood elevation, it is reasonable to assume that any development project that is contemplated within the mapped floodway on the island would be permissible from a floodway regulation compliance standpoint. The results of the Scenario 1 development scenario did indicate some minor base flood elevation increases (approximately 0.04 feet) throughout the stretch of the Mississippi River along the island and points immediately upstream. While these increases seem negligible, the federal, state and local floodway development rules clearly state that no increases in 100-year base flood elevation are to be allowed. 2. Scenario 2—Fill Entire Floodway Upstream of USH 61/151 A second floodplain development scenario that was evaluated with the Mississippi River floodplain hydraulic model included theoretically placing fill within all areas of the island that are mapped as regulatory floodway, but only those locations on the island located north of the USH 61/151 bridge. This scenario would essentially keep the regulatory floodway areas that are located to the south of the US 61/151 bridge undisturbed. The results of this hydraulic modeling evaluation indicated that increases in Mississippi River 100-year flood stage would only increase by approximately 0.005 feet. Given that conservative assumptions are still being made for placement of fill that would entirely occupy the floodway north of the US 61/151, it is reasonable to assume that the projects currently being considered in this part of the island would have little to no impact on Mississippi River flood stage. 3. Scenario 3—Fill Entire Floodway Upstream of USH 61/151 and Perform Minor Regrading South of USH 61/151 to Offset Minor River Flood Elevation Increases The third floodplain development scenario that was evaluated is identical to Scenario 2. However, in an effort to offset the minor Mississippi River flood stage increases that resulted from Scenario 2, some regrading of floodway areas on the island located south of the US 61/151 bridge are reflected in the hydraulic model. This potential regrading seeks to lower ground surface elevations in this area to near elevation 596. The Scenario 3 hydraulic modeling results indicate that no increases in Mississippi River flood stage would occur. C. Other Floodplain Development Considerations The previous section focuses primarily on development scenarios involving potential improvement projects within mapped regulatory floodway areas on the island. Given that construction within floodway zones is highly restrictive from a regulatory standpoint, it is an important step to determine what can and cannot feasibly be done in these areas. The results of the floodway encroachment analyses summarized in the previous section demonstrate that locating potential projects in the mapped floodway at the island appears to be feasible. However, development projects on other portions of the island also needs to be evaluated.

Chaplin Schmitt Island Floodplain Study As stated in the regulatory review section on Page 3, proposed buildings must be elevated to be equal to or greater than the flood protection elevation, which is equivalent to the regional 100-year base flood elevation plus 1 foot of freeboard (elevation 612.0). This is the minimum flood protection elevation standard that must be met. However, given that storm and flood events are growing in severity and frequency due to the effects of climate change and other threats, following a flood protection elevation standard that improves resilience of future buildings and projects on the island should be considered. The Federal Flood Risk Management Standard establishes a flood standard that helps achieve the goal of increasing the resiliency of future projects against flooding. Currently, the Federal Flood Risk Management Standard applies only to federally funded actions involving new construction, substantial improvement or repairs to substantial flood damage. It also applies to hazard mitigation projects involving structure elevation, dry floodproofing, and mitigation reconstruction. If federal funding is sought for future development and improvement projects on the island, applying the Federal Flood Risk Management Standard should be considered. If the Freeboard Value Approach (FVA) is applied, it would involve adding 2 feet to the base flood elevation for non -critical actions and adding an additional 3 feet to base flood elevation for critical actions. An alternative to the FVA is increasing the flood protection elevation to the 500-year base flood elevation, which in this case would increase the flood protection elevation by approximately 1.5 feet. Increasing the flood protection elevations for new buildings will result in greater cost to account for placement of additional fill to elevate structures beyond the minimum flood protection elevation standard. The increase in resiliency and mitigation of potential future flood risks will need to be balanced with the estimated increases in construction costs to comply with the more stringent flood protection standards.

RDG will prepare an opinion of costs for both options. Lighting Scenario Presentation — RDG will present the scenarios to the Chaplain Schmitt Island Task Force to receive input and direction. Using this feedback, RDG will prepare a meeting summary and recommended scenario to advance into an illustration showing the lighting scenario. Final Deliverables — RDG will Prepare one illustration that shows the lighting concept for use in promotional materials and a summary memorandum. Page 716 of 1050 �_.

Chaplain Schmitt Island Development Plan Public Comments Comments Received from 1013012024 - 1112612024 Page 758 of 1050 Submission Date First and Last Name Address City Comments Please move forward with the plan. For Dubuque to have a destination area would be great. The Q is making major improvements, and they have been doing evwrything right. 10/30/202415:06 Chris Schultz 2707 north grandview Dubuque The concert series they have is talked about regularly outside of Iowa. The crew they have with Alex, Brian and Chuck, and many others, are a credit to our city. I fully support the efforts there! I really think there would be better areas in the community to spend the money for something that is only used for part of the year. 10/30/202415:25 Ben Schildgen 2178 St. Celia Dubuque The infrastructure alone to handle the traffic and you would probably need another overpass of the train tracks. If traffic is to burdensome, people will stay away. I think usingthis island to make either more housing options or commercial is not a good idea. Part of the place parts of Dubuque is our natural beauty, 1, for one do not want 10/30/202417:54 Kari Christianson Dubuque to see this plan move forward. We haveother spots, other developments. Please leave this one alone! think using this island to make either more housing options or commercial is not a good idea. Part of the place parts of Dubuque is our natural beauty, I, for one do not want 10/30/202417:54 Karl Christianson Dubuque to see this plan move forward. We haveother spots, other developments. Please leave this one alone! A fitness trail would be a great outdoor place to get in a workout with fresh air. 10/31/20249:57 William Peterson 2550 Marquette Pt Dubuque While I like the idea of another splashpad in town, an area that is prone to flooding and difficult for kids to get to on their own doesn't make sense. How many months of the 10/31/202412:57 Kelly Fagan 3189 Kaufmann Avenue Dubuque summer can the splashpad actually be open if it is under water? What is the cost of upkeep and repairgoingto be forthe plumbing underground, plus the above ground structures when they are subject to frequent flooding? - Seems to be cramming WAY too much stuff into a small space. The artist renderings are way too much... way over the top and just always seem to be more elaborate than the last. I think this is probably the 7th iteration of this project that I've seen in the last 8 years. Each one becoming more unrealistic that the previous. Highway 151 looks like a luxury boulevard. The Peosta Channel looks like a Miami style Mardi Gras party is breaking out. None ofthis is remotely realistic and certainly should be taxpayer funded for commercial development. - Condos should NOT be allowed on the island. Not ever. Period. Especially if we are practically giving away prime real estate with great river views on the old Bowling & Beyond location to build even more affordable housinglapartments. Bet those luxury condos that Al Spiegel wanted to build in the past in some of the worst locations... aren't looking so bad now given the available real estate scattered all over the downtown area that similar buildings could be built. Today's cheaply built affordable housing (managed by out of state corporations that prey on their low income tenants) is tomorrow's ghetto. - Is the plan to evict Catfish Chrarlies? All the artist renderings seem to just erase anything that is in the way instead of working with the private businesses (that pay taxes, employ citizens, and are ocasionally profitable) to see what they need or how to include them into the planning. - I like the idea of a real amphitheater... unless it is going to be dug down into a potential flood zone and underwater after 1/4" of rain. I have noticed that the last 3 versions of this amphitheater have changed considerably, and diminishing in size. Are any of these plans actually being considered or should I just wait for the new design next year? - Recent plans announced to cram a "Top Golf" type of venue over the old dog track next to a new hotel that is crammed between the existing hotel and the Q-Casino and a new amphitheater. Has nobody noticed that just a few blocks away there are acres and acres of vacant land at the old Pack site that have been langusihing for decades now. Large enough to develop a properly sized venue for a Top Golf, or whatever, with great visibility from the highway and a short walk from both the Millwork District AND Schmitt island AND not in a potential flood zone. - The goal I keep hearing is to make Schmitt Island "a destination"withing Dubuque... Why should taxpayers subsidize trying to make the island the "only" destination in town when there are a number of other areas that are also great destinations but are left completely out of this narrow minded focus? - Parking on Schmitt Island is atrocious for events and it's going to get even worse. Parking on one side of the island and then having to walk around is dangerous. No sidewalks. Terrible lighting under the Wisconsin bridge is unsafe for pedestrians traversing around the island. Shuttles don't work because theyjust get caught in traffic. If we were able to find a way to bore a pedestrian tunnel under railroad tracks at the Bee Branch... boring a tunnel under the highway should be easy-peasy and with considerably less red tape. - Did I mention parking on that island is atrocious? Has anyone ever realized that if you are at a hockey game and you get stuck parking over by the vets memorial.... there is one way in and the same way back out. Getting out of that end of the lot is next to impossible and has only gotten worse with the expansion of the memorial into the parking lot because some architect had a lifelong dream to create a large Fibonacci spiral on the ground, which I know of no relevance or symbolic meaningto Veterans. 11/1/20240:34 Terry Demmer 4935 Wild Flower Ave Dubuque Couple of additions to the island that were somehow missed in this boondoggle of a plan... - How about building a few roller coasters on the island or perhaps a ferris wheel. - A carnival and a large scale petting zoo. -A massive indoor pool! - Daily parades with elephants, a dog and pony show, and maybe a few dancing panda bears. - Maybe a half dozen round -a -bouts. on streets that have little or no traffic. Page 759 of 1050 11/1/2024 11:14 11/1/2024 20:58 Jared McGovern Adam Riegler 12451 Oak Brook Place 2626 Glenview Circle -A Monorail! - A few car washes, a credit union or two, 3-4 mexican restaurants all with the word "Margarita" somewhere in their name, and an empty strip mall. - A parking ramp... No, better yet... TWO parking ramps and both will be underutilized. : I'm saying is that YOU are tryingTOO hard to do TOO much with an area that isn't nearly the problem as what the money hungry developers (who are far too eager to line pockets with more taxpayer funded projects) are trying to portray it as! There is such a narrow focus on a few acres of land that is propped up out of the river by a former garbage dump. Yet other areas of this city continue to decay. Kerper Blvd is a desolate relic of past industry. The River Museum exhibits are under constant updates but the quality of some of the updates when completed is abysmal (seethe recently "redone" erosion table... Or that beautiful plywood sided tank for paddlefish. Or the sterile wooden box home for a few raptors or owls outside. Or how about the historic William Black moored in the ice harbor that looks more like an actual floating garbage dump of rotting wood and peeling paint than a historic vessel. Based on the track record, I can't wait to see how badly built the new otter exhibit is goingto be!). Five Flags is no better nowthan itwas 20 years ago. unless it has actuallyfound it's new calling as a pickleball court. The new dock for excursion boats at the river walk... still hasn't happened. The original planned round -a -bout at Asbury & University (where a round -about is ACTUALLY needed)... Ilkley forgotten when it should be relatively simple. Eagle Point Park needs serious attention to restore buildings but also to modernize them and make them desirable for renting. The north end has crumbling buildings and concrete relics of foundations. The "South Port" has had about a half dozen iterations of costly development studies. The added 2 lanes for the Julien Dubuque bridge never happened... but the businesses in the way were quickly forced out for yet another project that was never completed. Half of the office space or more in downtown is sitting completely vacant. We hear endless discussion about converting Central avenue into 2 way streets as THAT is entirely what will make businesses there successful (if the population doesn't see a heavy need for something and surveys says it's 50/50, is there actually a problem and is changing the direction of a few cars and spending a lot of money reconfiguring streets and infrastructure really goingto solve the real problem? Our city parks and playgrounds are not being maintained. The shot tower is a national historic landmark and yet there are zero plans to tie it to the river walk area and make it more accessible. The Millwork area according to some of the beautiful artistic renderings, originally had a beautiful city park planned in the middle... then we built a parking ramp in it's place before the park could ever happen. Our airport terminal... a beautiful project with all the modern updates.. now if only we could actually use it for consistently boarding and deboarding planes (plural) like the ones that were shown in the pretty architectural drawings. If there is one thing this town is good at... it's hiring consultants and architects to draft up expensive lengthy reports, loaded with extravagant pretty pictures showing full grown lush trees and green spaces (which are really parking lots in disguise) and immaculate landscaping. The wonderful reports will include a bunch of generic photos of Stuff from cities with well over lox our population, and create larger lists of pipe dreams that never happen. Dubuque is a place where we dream of things s0 big and s0 costly, that the costs can never be justified. Because of that, real progress rarely happens. Our ambitions are always on a massive grand scale, wiping out entire areas and Starting from a clean slate. We manufacture false problems in places like Schmitt Island and try to sell the public on expensive solutions. What we really need is to look at a few of the real priority problems. Solve them on a manageable scale, and then do it again, and again. Year after year. It may not be massive and grand in scale, but at least we would actually be DOING something that could be called progress. Amazingly well thought our and visionary. Thank you! 1. 1 love the idea of and Education Outpost on the Island connecting the community directly to the Mississippi River and the Upper Mississippi River W ildlife and Fish Refuge 2. The forest restoration and additional access plans are inspirational. 3. The observational tower, the hotels, the walking trails, the campsite and cabins combined with create the birding basecamp for the Dubuque area and ideally lead to the creation of a formal birding trail in the tri-states. There is big money here and birding is one of the entry points into nature connection activities that is equitable and Dubuque accessible to all. 4. Please prioritize the additional pedestrian access and public fishing access. With the new affordable housing development being built on the former Bowling and Beyond site we this access will make the islands natural resources and amenities even more accessible to Dubuque residents. 5. The responsible use of public funds in this endeavor is a testament to the leadership and committed residents in Dubuque. Public, Private Industry, Charitable Non- profits, Investors, Developers, all coming together around a common vision. Alex Dixon. Thank you for being such a powerful and dedicated ambassador for Dubuque. 6. "Dubuque deserves nice things" (Alex Dixon). This plan, this investment into the recreation, entertainment, river access, and tourism attraction will retain and attract a diverse, and talented workforce to Dubuque and will compliment the investments already made in our community and those currently underway. 7. The only addition I would make to this plan is the addition of an indoor sports complex that would expand the ability for the island t0 attract youth athletic events year round and when the education outpost opens and the public fishing spaces are built that you focus on activating the island all four seasons. What does winter recreation look like on Schmitt Island! This is an incredibly ambitious project and so many amazing ideas have been proposed! One thing I hope can be incorporated into the whole masterplan is rebuilding the skate park that has long called the island home. As a lifelong Dubuquer and skateboarder, I practically grew up at that skate park along with so many other people in the Dubuque Dubuque action sports community. There is a large group of people that would be more than willingto do whatever it takes to make sure this little piece of "paradise" can be saved, improved upon or eveb rebuilt entirely. Look no further than local events such is Bloktoberfest, or the recently expanded 011iewood Action Sports indoor facility on Cedar Cross Rd just to see how passionate the people in this community are about action sports. I just wanted to voice my support for this specific feature of the island and Page 760 of 1050 11/3/20247:39 Rickey Canner 2003 washington street Dubuque Hello, our family is season ticket holders for the Fighting Saints. I don't think an apartment complex should be placed next to the rink. Parking! s a big issue. The players should have their own parking closer to the building. They shouldn't have to share with the fans. I know extra parking is in the plans, but I feel the apartment complex would be abetter use of space for parking forth a rink and the Hotel that you want to put next to the rink. I feel that on 16th street is a big open field to build the apartment complex. It would be a great use of that space. In my opinion. Thank you for you time, Rickey Canner This is all merely food for thought. Concerning the Apartment Building 1) Why apartments? Why not condos which typically have greater emotional investment from residents? 2) Tuck Under Parking - great to avoid another surface lot, even if not fully underground. 3)This is basically "luxury building" for Dubuque if the idea is "the complex would be expectd [sic]to balance high enough price points to maintain a rate of return that 11/4/202411:29 Susan Price 653-1/2 White St Dubuque supports the development:' 3) Only 3levels? Only 72 units? Seems small for a luxury development on the waterfront. 4) No rooftop deck, no fitness center? Seems odd to not have these amenities in any new residential development of this size these days. 5) This is a pretty isolated residential development. Where do residents buy groceries, since there is minimal on nearby mainland. Is there a facility on premise for delivery of packages, including groceries and other perishables? What kind of security is there, is any door personnel planned or can anyone just walk in with a code? 6) AirBnB is allowed? From the outset? Who would own these units to AirBnB them? To allow AirBnB in this public manner directly conflicts with the City's housing shortage that is already heavily and negatively affected by AirBnB and similar. People who live in large residential buildings increasingly have negative views of units being used solely as short-term rentals: they want quiet neighbors who live there and care what happens there next month. 7) On quiet neighbors, it seems that developers do not always take soundproofing seriously enough, even in new luxury buildings. Just saying. Concerning Destination Play 1) How much will a day pass or monthly pass cost? Cool indoor facilities in metropolitan areas can easily charge $30 per child for two hours and must be accompanied by at least one adult (often additional charge for second adult). 2) How will this impact small businesses offering similar services in Dubuque? Tax Status How much of this entire development is happening under the aegis of a "non-profit" that is being used as a business model while it enriches directors, CEOs, and similar while taking funding from non -profits offering social services and similar? Many area "non -profits" offer housing, recreational, and entertainment services that compete with small businesses with traditional tax statuses, putting the latter at financial disadvantage in this community because they cannot charge for the true cost of services. Further, the employees of these area "non -profits" often struggle to survive while their directors are thriving (to be clear, no one should have to struggle). Real conversation: "They've not given you the raise they said they would nine months ago, still?" - "Well, they keep telling me they will. It is a non-profit after all" - "You are struggling to survive. What kind of car does your director drive? You think he's struggling? We both know he's not:' Again, just food for thought. Page 761 of 1050 I cannot believe the amount of excessive, wish -list style ideas and improvements that's being focused on an island in the flood plain that was a former landfill. I support ecological restoration, and private development that is undertook through private funds. Tree houses? New bridges? Fancy playgrounds? Let's be down-to-earth with these items. The city is just trying to project itself onto the island, as it has done at many points in history, rather than letting the island be what it wants to be. As climate change ramps up, this will just become another eyesore in Dubuque when maintenance costs skyrocket, or get neglected while the city focuses on whatever new 11/10/202414:49 Christopher Bechen 2001 Shires Ave Dubuque pet project is next. We need to focus on maintaining our current resources, or developing currentlyvacant land. Look at the old pack and areas in the Port, and areas along Kerper. Finally, I think it a poor choice to locate a roundabout directly next to a highway entrance and high truck traffic. People will go so fast through here, and double -lane roundabouts are difficult to navigate. The amount of near -misses and blatant wrong and unsafe driving practices on the Kerper Roundabout compared to the grandview ones should serve as a serious warning sign.(I do landscape maintenance for the city on all three and have lots of time to observe.) I don't think we should be afraid of stop lights. This is a wonderful plan and this really needs to happen for the community. Having a destination spot in Dubuque will be fantastic and grow the city. Inparticulartheice arena updates will have a huge impact on all the current residents of the rink. As it stands today we have several programs using the facility and frankly it is extremely 11/12/202416:26 Matt Timmons 1265 Cortez Drive Dubuque crowded with limited locker room space. Also hosting youth games and tournaments across age groups is verytough in current state. With some teams only getting to have 6-10 home games and having to play 25-35 games away from home. The addition of college hockey is wonderful for the youth programs but to see its full value adding another rink will expand on the growth tremendously. Please begin the execution of this development plan for our community. Thankyoul Dear City of Dubuque, It is with much interest that I read the development plans for Chaplain Island. I was part of the planning process more than 20 years ago that discussed innovative ideas for this unique and important part of the city of Dubuque. Although, some of the plans include ecological and environmental improvements. It is disheartening to seethe commercialization of citizens only access to the Mississippi River. Additionally, it is disingenous to not tell citizens the truth about #13 and then later on say recreational center- TBD- Private. It has already been in the TH and many citizens are aware that a land swap is proposed between the company that purchased the Dubuque Soccer Complex. Thus, it seems as if city officials and the DRA are trying to hide the fact that they will be giving away a portion of the most precious land in Dubuque. Unfortunately, 11/12/202417:47 Heather Trees 3578 Burtons Furnace Ro Durango this company has already caused great consternation and heartache in Dubuque for many reasons including refusing to workwith AYSO, not completingtheir upgrades to the Soccer Complex and not creating a recreation center mainly for volleyball players. Thus, it is interesting that you believe they will be good partners and want to give them prime access to city land. I predict many Dubuque residents will be outraged by this decision which is why you are hiding it from the public during the public comment period. Also, indoor recreation space is not what should be prioritized near the Mississippi River. We have so little access to riverfront as citizens. Taking it away to create an indoor facility that can go anywhere in Dubuque or its environs is a poor use of the land. I know many will say you want to group the travel team recreation together. But as a longtime travel team parent, I know you don't even look outside when watching your kids play sports. It is also clear that you are trying to drive business to the proposed hotel. But as many studies have shown, Dubuque is already over built when it comes to hotels. This will only hurt existing hotels which should be of concern to the city and its leaders. Unfortunately, it is just another example of the city prioritizing its casino over other amenities in Dubuque. I urge you to not prioritize commercial investment from companies that are not a part of Dubuque's fabric. The plan clearly favors visitors/tourists over residents and our ability to access Dubuque's most significant and visible asset -the Mississippi River. Please reconsider your plans and please be honest with the public about the proposed "recreation center" deal already in the planning stages. Thank you for taking the time to read citizen's comments. Sincerely, Heather Trees I am a local resident that is opening a bouldering gym downtown on main street. Our project was awarded a main street Iowa challenge grant and i am writing in regards to 11/12/202419:47 Annie Sharp 1421 Elm St. Dubuque the destination play part of the project- we have been working hard to open a local bouldering gym that can be a third space for the community. Including a bouldering facility on the island will likely greatly negatively effect our efforts and detract business from our small local gym. However, i do feel including a roped climbing wall could potentially enhance both our businesses due to the complementary nature of both types of climbing. Probably best for us to be the only climbing in town but if that isn2€'"t in the cards, please consider a rope wall and leave the bouldering to us at Slanted Climbing. I would like to see an indoor basketbalWolleyball facility that could be used all year round like all the other towns have even the small towns have these facilities, but 11/13/20247:30 Richard Herrig 2525 Viola Dubuque Dubuque doesn8€"t. Page 762 of 1050 I strongly support the adoption of the 2024 Chaplain Schmitt Island Development Plan. This visionary plan presents an exciting opportunity to transform Schmitt Island into a vibrant destination that will greatly benefit Dubuque's economy and create a lasting legacy for future generations. The development plan outlines a comprehensive strategy to create "Dubuque's Gateway to Entertainment and the Mississippi,' leveraging the island's unique location and existing assets. By focusing on a mix of entertainment, recreation, residential, and commercial uses, the plan aims to attract both visitors and residents, driving economic growth and enhancing quality of life. This plan would provide a significant economic boost to Dubuque in several ways: 1. Job Creation: The proposed developments, including hospitality, retail, and entertainment venues, would generate numerous new jobs across various sectors. 2. Increased Tourism: By creating a unique rive rfront destination with attractions like a marina village and amphitheater, the plan would draw more visitors to Dubuque, boosting tourism revenue. 11/13/202413:38 Sabrina Ocampo 598 University Dr Dubuque 3. Private Investment: The plan is designed to attract substantial private investment from local, regional, and national sources, stimulating economic activity. 4. Tax Revenue Growth: New residential and commercial developments would expand the tax base, providing additional resources for city services and improvements. 5. Diversification of Local Economy: The proposed mix of uses would help diversify Dubuque's economy, making it more resilient to economic fluctuations. Furthermore, this plan represents a valuable investment for future generations: 1. Environmental Stewardship: The plan emphasizes restoring and enhancing the island's natural resources, preserving this unique ecosystem for years to come. 2. Improved Infrastructure: Proposed improvements to transportation and utilities will create a more connected and resilient island. 3. Housing Opportunities: The inclusion of residential development will provide new housing options, potentially attracting young professionals and families to the area. 4. Recreational Assets: Enhanced public spaces, trails, and recreational facilities will provide lasting benefits for community health and well-being. 5. Cultural Enrichment: Proposed arts and cultural venues will contribute to Dubuque's cultural landscape for generations to enjoy. The 2024 Chaplain Schmitt Island Development Plan aligns closely with Dubuque's Five -Year Goals, demonstrating a thoughtful approach to community development. By adopting this plan, Dubuque has the opportunity to create a truly unique riverfront destination that will drive economic growth, enhance quality of life, and leave a positive legacy for future generations. I urge the City Council to approve this forward -thinking and transformative plan for Schmitt Island. Page 763 of 1050 The plan looks very ambitious for making the Island a destination for all. Top concerns/questions: -Investing this amount in island - how will this impact Five Flags and its future and funding available for it? How will it impact having sufficient funds for other areas of the city in need of funding especially north end of Dubuque which is in need of city investment and support? -How will building on a former landfill site be addressed to minimize maintenance and issues to building on such a unstable surface. There is additional cost with building on this type of surfaces - how is city plan to address this upfront to minimize long term cost and ensure structures are able to withstand environmental changes -how will climate changes impact the island and how especially area that is in flood zone? I will city mitigate and prevent and loss associated with increase natural hazards? -How will city address displacement of homeless that are living on island? This is a major concern as there needs to be more places in the city to serve/assist this population. -parking - if this becomes a destination will there be sufficient - free parking so everyone can take advantage of the improvements? 11/13/202415:48 Dawn Danielson 7600 S Westbrook Dr Dubuque Pros: -Love focus on ecological enhancements and incorporating elements to improve the esthetics -the Peosta bridge is neat way to connect existing flood wall to island -like variety of outdoor/indoor activities planned and additional hotel accommodations - would like to see the private investments and grants take lead on this versus a ton of local funds -great visual of possible redevelopment on pdf page 20 -love entertainment zone outlined on pdf page 35 and public promenades on pdf page 36 -love ecological components outlined throughout plan Thank you for sharing this plan and posting to the city's website.

We will not leave without a fight. Chaplin Schmitt is my relative My comments are regarding the removal of invasive species on the island. I spend a lot of time walking the trail, and cleaning up the shoreline on the north side and the east border of Heron Pond, where trash from fisherman and the rivers rise and fall accumulates. The islands ecosystem has many small fur bearing animals including red fox, raccoon, muskrat, beaver, rabbit, groundhog and squirrels. From my observation, the invasive species such as the Box Elder tree seeds and the Maple tree seeds are the 11/15/20248:58 Carol Petrick 2605 Fulton St Dubuque squirrels main food source. While the wild grapes from the vines seem to be one source forthe red fox, raccoon and bird populations. This is not an optimum diet, they are merely making do, while being relatively trapped on this island. If these invasive plants are removed, please plant native nut and fruit trees and possible berry bushes on appropriate elevations for these animals to survive on. This natural woodland area in the midst of a city is a gem that does not require much or any car travel for residents to access. Nature, not development is such a healthy reprieve from the stresses of modern society. Thank you. In looking at the plans presented at the public meeting on Nov 12, 1 would like to express my concerns for anything that would affect the flow of the Peosta Channel. The islands and pedestrian bridge that are suggested would add to the sitting in problem the channel already has. People can walk easily to Schmitt Island with the existing walking/bike path already. The islands would aggravate an already existing sitting problem, affecting boat traffic in this area. Typical flooding could easily negatively affect 11/18/202410:51 Dawn Pregler 13235 Terrell Ridge Dubuque these two features. The usualfloods don't just increase the flow and volume of water, but trees, sticks, mud and anything that floats -which need to be cleaned up and clearedout. Go to the public fishing dock or Ski Club to see this year's leftover debris. And last year was 10 time worse. In looking at the plans overall, they might be good in theory, but I don't think some are practical. It's an island. It floods. Then you have no access, and a mess to cleanup besides. The river always wins. I don't think it's a good idea to put in so much money to parts of this project when Mother Nature decides your ability to use them. think that a rotlerblading/ skating rink would be a very fun addition to the recreation plans, as we have no longer have one in town. I think it would be a success with 11/24/202420:17 kylee 2415 Windsor Ave Dubuque dubuquers and for visitors/ tourists of all ages. Page 764 of 1050 11/25/20247:37 Craig Uhlenhopp 3305 Carlton Or Cedar Falls City of Dubuque Ad mini strators, I am a resident of Cedar Falls and an 11 year veteran of the Dubuque Yacht Basin. We looked at multiple marinas from Lansing to Davenport before landing in Dubuque. We wanted a safe place to leave our boat and a covered slip. The Yacht Basin has been perfect. It is disturbing to hear that a marina along the river may go away much less the one we have been at for so long. (We have dock mates that have been on site for 35+years) In order to have a marina as we know it means gas, pump out and service facilities. Not to mention boat storage for the cold months. If this marina goes away people will be forced out of the Dubuque area as the other marinas cannot Support the exiting boats from the Yacht Basin. We spend a lot of money in Dubuque everyyear. You do not see it in your tax base, but it is spent in town anyway. Whywould a city turn a blind eye to that? We are not the only ones that travel to Dubuque. I know people from West of Ft Dodge, Madison, Janesville, Cedar Rapids, Ames, Ankeny, Platteville, Maquoketa, and Clinton. Just to name a few. They, like us, do the trip every weekend in the summer. Some of the plans obviously reflect ideas that will not work with the river unless there is an unlimited budget for dredging and USACE. Please do not cut the tourism that you already have. Thank you for your time. Craig Uhlenhopp The Veterans Memorial Plaza is a cornerstone of Chaplain Schmitt Island. In addition to commemorating and memorializing service, sacrifice and valor, the Plaza provides an opportunityto educate visitors. As a retired Air Force space operations officer, I suggest the Plaza should be updated to more fully recognize both our newest military service s€" the Space Force, and ongoing Global War on Terror operations. Additionally, I recommend that the inaccurate statistics on some of the central pillars for Americas€'°s wars be corrected. Specifically, in the Veterans Memorial Park Project, in addition to an entryfor s€ceOverlook/Trails€, I suggest including a description and funding estimate to: 1) Include the Space Force seal and imagery on equal footing as the Army, Marine Corps,Navy, Air Force, Coast Guard and Merchant Marine. Currently, the Space Force is only recognized by a flag. 2) Update the Global War on Terror pillar to include operations initiated after Operations Enduring Freedom (OEF) and Iraqi Freedom (OIF). Since the Start of the Global War on Terror in 2001, there are 7 additional significant named operations qualifying for the Global War on Terror Expeditionary Medal. 3) Correct KIA (killed in action) statistics on the pillars for Civil War, Indian Wars, Spanish-American War, World War I, World War 11, Korean War, Vietnam War and Gulf War. BACKGROUND FOR SUGGESTED CHANGES s€" Veterans Memorial Plaza 1) The large, black stone wall that dominates the center of the Veterans Memorial Plaza currently has the service seal and imagery for the Army, Marine Corps, Navy, Air Force, Coast Guard and Merchant Marine. But the Space Force seal and related imagery is not included. The Space Force is acknowledged by a flag. - The Space Force should be treated as a co -equal military service. 11/25/20249:21 Dean Boles 1715 Geraldine Dr Dubuque - In addition to commemorating and memorializing veterans€"s service, I thinkit is importamto educate visitors. 2) Global War on Terror (GWOT) pillar lists only Operations Enduring Freedom and Iraqi Freedom.

A task force of the Dubuque Audubon Society Conservation Committee met to review and discuss the plan, and to tour the island. The Audubon Society provides the following recommendations: General: 1.Conserve and protect the remaining ecological integrity of the island; establish natural resource conservation as a priority threshold, not one to be a€cebalanceda€ with or compromised for recreation, housing or economic development. 2.State that all future island development will accord with and not hinder wildlife habitat goals, adhering to federal Endangered Species Act and Migratory Bird Treaty Act requirements. 3.Specifically include birds (waterfowl and passerine, both resident/nesting and migratory) in definition of wildlife for purposes of wildlife habitat protection and development. 4.Conduct baseline survey counts of bird and other wildlife users and residents of the island. 5. Manage current and future lighting to reduce impacts on wildlife, especially during spring and fall bird migration. 6. Define &€caundesirablea€ native vegetation. 7.Specify the parameters of the a€cecurb appeals€ zones. B.Identifythe pace of mature tree removal.

Does the project help advance the islanda€s appeal from a wildlife habitat, bird migration or and beatification standpoint? 2espectfully submitted, 'huck Isenhart ;hair, Dubuque Audubon Society Conservation Committee After reviewing options forthe development of Chaplain Schmitt Island I am disappointed in several areas. Our responsibilities to the Riverfi€'"s health here in Dubuque and downstream were largely glossed over. Spraying herbicides along the Rivera€'s edge and increasing impermeable spaces damages the best of what Dubuque has to offer - life on the Mississippi. Not too far downstream there are no water sports, no fishing, no wildlife watching; the river is too polluted. Also neglected is our responsibility as an 11/26/202417:24 Ashley Neises 735 Rose Street Dubuque informed public to consider life near the river as weather events become more extreme. The efforts needed to make the Island an opportunity for appealingtax revenue seem to cast doubt that climate change is largely undisputed by science as FACT. To develop in a floodplain presents Dubuquers as ignorant to the challenges ofthe Mississippi River Valley. The developers of this plan are clearly thinking of short-term gains rather than the longterm health and vibrancy of Dubuque. Furthermore, the effor to develop this portion of the riverfrom for tourism or new housing will not benefit the neighbors near this proposed development. The Plans intention is clear on that. No amount of bright shiny lights or promises can improve neighborhoods that will be left in the dark. I am very disappointed that in 2024 Dubuque leaders have visions of Las Vegas, Nevada of the 1950s. This Plan is outdated, irrelevant to our rich river heritage, and is a lacking resilient or sustainable measures. We can do better. Thank you. Miller park has direct access to the Mississippi River, the only direct access in the city. Why not dredge t0 bring the park above the flood stage like the rest of the island. 1 11/26/202420:29 Bob Bierie 16076 Budd Rd.

Page 767 of 1050 The Chaplain Schmitt Island Development Plan Open House took place on November 12 from 6:30 to 8:00 p.m., drawing approximately 50 attendees. Among those present were city staff members, including: • Marie Ware, Leisure Services Director • Jill Connors, Economic Development Director • Wally Wernimont, Planning Services Director • Nathan Steffen, Civil Engineer Other notable attendees included: • Alex Dixon, President and CEO of the Q Casino and DRA Board • Rick Dickinson, CEO of the Greater Dubuque Development Corporation The event featured presentations by key individuals involved in the development process. Wally Wernimont, Director of Planning Services, provided an overview of the Chaplain Schmitt Island (CSI) development plan, explaining its origins and evolution. He highlighted that the City Council had identified the CSI Master Plan as a priority goal in 2013 and noted the development of the plan in 2014, along with an amendment in 2017. Wernimont also discussed the creation of the CSI Design Guidelines, the island's zoning as a Planned Unit Development in 2017, and the work of the DRA on various CSI Placemaking & Implementation Plans in 2017, with updates in 2018 and 2022. Alex Dixon then gave a presentation on the history and role of the Q Casino (formerly the Greyhound Park and Casino) as a nonprofit entity. He discussed how the CSI Development Plan aligns with the overall goals of the CSI Master Plan, emphasizing its ecological and economic considerations. Dixon explained how the plan advances the Master Plan by adding financial details and prioritizing key elements. To facilitate engagement, city staff displayed 20 large-scale prints of pages from the CSI Development Plan around the room, in addition to copies of the CSI Master Plan, related ordinances, and placemaking plans. Attendees were encouraged to review the materials and ask questions. Wally Wernimont, in his capacity as both the Planning Services Director and Floodplain Manager, addressed questions related to the floodplain. The public was invited to share their feedback via comment forms, which were available both in paper form and online. Written Comment provided were the following: Public Boat Ramps is a must! Public Beachfront a bonus! Your islands will cause the P. Channel to silt in and become worthless as a waterway. Page 768 of 1050 Flooding is more than a problem of too much water — then receding. Look at the whole trees and debris and mud left behind now. All beach sand will be buried under mud annually w/ flooding. Need to have boat parking (slips) close to the "Q" so we can walk to it for lunch, etc. & stay over in hotel. Concern with noise and hours of operation from the concerts. Enforce the Noise Ordinance.

This review took place at a regular meeting of the Commission on November 20, 2024. Background The 2024 Chaplain Schmitt Island Development Plan builds on prior planning efforts including the Chaplain Schmitt Island Master Plan, Placemaking Plan, and Design Guidelines. Commissioned by the Dubuque Racing Association (DRA), the purpose of the development plan is to research the island's ecological and natural environment, analyze the floodplain, conduct market and economic assessments, evaluate economic feasibility, review infrastructure needs, and estimate costs for potential development.
