Van Milligen, City Manager SUBJECT: Upper Bee Branch Creek Railroad Culverts Project, Award Contract [CIPs 2642769, 7202769, and 3402769] DATE: February 13, 2019 Sealed bids were received for the Upper Bee Branch Creek Railroad Culverts Project. City Engineer Gus Psihoyos recommends award of the construction contract to the low bidder, Tricon General Construction, Inc., in the base bid amount of$25,900,000, which is 1 .24% over the engineer's estimate of$25,582,982. The recommendation outlines a plan that will allow the contract to be awarded and the project to proceed without increasing planned debt for the project and without increasing previously adopted stormwater utility rates. The recommendation will, however, require rescheduling other phases of the overall Bee Branch Watershed Flood Mitigation Project because it includes shifting funding for other phases of the overall watershed project to this phase. Since 1999 there has been six Presidential Disaster Declarations which included the Bee Branch Creek Watershed. The Drainage Basin Master Plan was completed and adopted by the City Council in 2001 . Based on a subsequent study in 2009 by the Federal Emergency Management Agency (FEMA), there are 1 ,373 properties in the flood prone area. In addition to homes, there are over 70 businesses in the at-risk area with over $500 million in annual sales. The flood prone area in the Bee Branch Watershed encompasses historic neighborhoods offering some of the community's most affordable workforce housing. Most residents are working families, many are elderly -- those least likely to recover from repetitive flood loss. Repetitive flood damage leads to disinvestment; from 2004 to 2009, while commercial property values grew by 39% citywide, they fell by 6% in the Bee Branch Watershed flood prone area. Since 2001 , the City has implemented many of the improvements outlined in the Drainage Basin Master Plan. But since 2001 several intense, storm events have occurred in the Dubuque metropolitan area so that revisiting the predicted hydrology and hydraulic behavior of the Bee Branch Watershed was appropriate. Over a twelve- year period starting in 1999, there have been three 100-year storms, two 50-year storms, one 25-year storm, and one 10-year storm. Finally, it is important to consider how additional flood mitigation efforts undertaken by the City since 2001 fit with the overall effort to mitigate flooding. Therefore, work began to update/amend the Drainage Basin Master Plan. On November 18, 2013 the City Council passed Resolution 335-13 adopting the 2013 Drainage Basin Master Plan Amendment. The 2013 Amendment did not replace the 2001 Drainage Basin Master Plan. Instead, it built upon its foundation. The amended Drainage Basin Master Plan outlined several improvements throughout the Bee Branch watershed to mitigate the effects of future flooding and disasters. Collectively, the improvements form the basis of the Bee Branch Watershed Flood Mitigation Project outlined below: Twelve phases of the Bee Branch Watershed Flood Mitigation Project Phase Description 1 Carter Road Detention Basin Complete 2 West 32"' Street Detention Basin Complete 3 Historic Millwork District Complete 4 Lower Bee Branch Creek Restoration Complete 5 Flood Mitigation Gate Replacement 6 Impervious Surface Reduction (Green Alleys) 7 Upper Bee Branch Creek Restoration, including the Upper Bee Branch Creek Railroad Culverts Project 8 22"a Street Storm Sewer Improvements 9 Flood Mitigation Maintenance Facility 10 North End Storm Sewer Improvements 11 Water Plant Flood Protection 12 17'h Street Storm Sewer Improvements The City of Dubuque has received approximately $160 million in grants to help fund the $219 million Bee Branch Watershed Flood Mitigation Project. The Project will prevent an estimated $582 million in damages over the 100-year design life of the project. Due to the contributions of local, state, and federal funding partners, Dubuque citizens will see a return on their investment of more than $8 for each $1 spent. The Bee Branch Watershed Flood Mitigation Project represents a multi - phased, fiscally responsible investment. It reflects a holistic approach to mitigate flooding as it will also improve water quality, stimulate investment, and enhance the quality of life of watershed residents. On December 4, 2013, the lowa Flood Mitigation Board voted to approve the City's use of$98,494,178 for the Bee Branch Watershed Flood Mitigation Project. On February 3, 2014 the City Council adopted Resolution 31-14 authorizing the execution of an agreement with the State of lowa Flood Mitigation Board and authorizing the City's use of sales tax increment funding for the Bee Branch Watershed Flood Mitigation Project. A great deal of the debt the City of Dubuque has incurred is for implementation of this flood mitigation plan. The state grant funding and the subsequent debt issuances allow much of the protection to be provided over the next six years, instead of over the next 20 years (only some of the 240 alleys will take up to 20 years). 2 On March 5, 2014 the City Council passed Ordinance 16-14 establishing the stormwater utility fee rate structure necessary to fund the various phases and improvements associated with the Bee Branch Watershed Flood Mitigation Project. Current Stormwater Utility Rates FY22 FY15 FY16 FY17 FY18 FY19 FY20 FY21 & Be ond Current Rates Per Ordinance $5.98 $6.38 $6.81 $7.27 $7.76 $8.29 $8.85 $9.00 16-14 In December of 2004, the City Council adopted the alignment for the Bee Branch Creek Restoration Project based on the work and recommendation of the Bee Branch Citizen Advisory Committee. The adopted alignment crossed the railroad yard at 506 Garfield Avenue now owned by Canadian Pacific. Completed through multiple contracts, again due to funding in 2015, the City proceeded with the construction of the Upper Bee Branch Creek Restoration Project. In May of 2015, the City Council awarded the contract for the Upper Bee Branch Creek — Channel, Streets, & Utilities Project. In May of 2015, the City Council awarded the contract for the Upper Bee Branch Creek — Structures Project. In October of 2015, the City Council awarded the contract for the Upper Bee Branch Creek Mississippi River Trail Project, the third contract associated with the Upper Bee Branch Creek Restoration Project. In December of 2015, the City Council awarded the contract for the Bee Branch Creek Basin Overlook & 22"d Street Parking Lot Project, the fourth and final contract associated with the Upper Bee Branch Creek Restoration Project. The improvements were substantially complete by July of 2017. In January 2016, the State was awarded $95.7 million in HUD National Disaster Resiliency Competition grant funds. Per the award, the City of Dubuque is to receive $8.4 million for a comprehensive "Bee Branch Healthy Homes Resiliency Program" to help residents address residual impacts from the flooding experienced within the Bee Branch Watershed. The City is also to receive $23.1 million for storm water infrastructure improvements associated with the Bee Branch Watershed Flood Mitigation Project. The infrastructure improvements included the (Upper) Bee Branch Railroad Culvert Infrastructure Improvements through Canadian Pacific property at 506 Gartield Avenue. With the $8.4 million Bee Branch Healthy Homes Resiliency Program grant, this is the first time the City has been able to help property owners repair their flood damage in any significant way. The City currently has accepted over 550 applications and approved 213 of them. Of those 213 applications that have been approved, 61 units have received resiliency work and are completed. Another 28 units are currently being 3 worked on and an additional 11 units that are out for bid. Almost $2.5 million has been spent so far on these projects. In addition to this work that has been done, the Home Advocacy Program, led by the Visiting Nurses Association (VNA) has reached out to all of the tenants of these units. Not only has the VNA discussed the resiliency part of the program, but the VNA has also shared expertise on the following subjects: Education, Child Care, Health, Financial and many more areas of concern. T hey want these tenants to know that there are resources available to them, upon request, for any and all of their concerns. In October of 2016, the City Council adopted Resolution 362-16 authorizing the execution of a contract with the lowa Economic Development Authority (IEDA) in order for the City to utilize $23.3 million in HUD National Disaster Resiliency Competition grant funds for the Bee Branch Watershed Flood Mitigation Project with $9,000,000 specifically for the proposed culverts from the Lower Bee Branch Creek, through Canadian Pacific Railway property, to the Upper Bee Branch north of Garfield Avenue. This phase of the Bee Branch Creek Restoration Project is also referred to as the Bee Branch Railroad Culvert Infrastructure Improvements Project. The contract with IEDA requires that the City complete all of the improvements by June of 2021 . In December of 2018, the City Council adopted Resolution 385-18, authorizing the execution of a Construction Agreement and an Environmental Right of Access Agreement with Canadian Pacific Railway. The Upper Bee Branch Creek Railroad Culverts Project (Project) represents the final contract associated with the Bee Branch Creek Restoration Project (Phase 4 & 7 of the Bee Branch Watershed Flood Mitigation Project). The improvements will allow for the efficient flow of floodwaters from the recently completed upper Bee Branch Creek improvements, through the railroad yard on Garfield Avenue, to the lower Bee Branch Creek. Project elements include the installation of six, 8-foot diameter culverts under the railroad tracks using tunneling methods. In addition to other elements, the design will allow the existing box culverts to serve dual functions: flood control and as a hike/bike path under the railroad tracks. On February 5, 2019, the City received five bids for the Upper Bee Branch Creek Railroad Culverts Project. Tricon General Construction, Inc. submitted the low base bid of$25,900,000.00, which is 1 .24°k over the engineer's estimate of$25,582,982. In addition to the base bid, there were alternate bid items. In conjunction with the preparation of the Fiscal Year 2020 Budget, the funding plan and schedule of the various phases of Bee Branch Watershed Flood Mitigation Project were considered. The construction contract budget for the Upper Bee Branch Creek Railroad Culverts Project was set to match the engineer's base bid estimate of$25,582,982.00. The construction contingency budget to be used to cover unexpected work that might 4 arise during construction was set to be $1 ,279,149.00 (5°k of the construction contract budget). Because the low base bid received is $317,018.00 more than the proposed budget, there isn't funding within the budget to do the additional work outlined in the alternate bid items. But as the project proceeds toward completion, and the need for the contingency funding is better understood, it may be possible to re-bid the alternate bid item improvements and construct them with contingency savings. The City will also continue to look for grant funding assistance to help cover the cost of the alternate bid item improvements. In order to award the base bid construction contract and cover the $317,018.00 shortfall, the recommendation is to adjust the funding and schedule of other phases of the overall Bee Branch Watershed Flood Mitigation Project versus increasing the planned debt for the project or increasing previously adopted stormwater utility rates. While the final completion date for the Upper Bee Branch Creek Railroad Culverts Project is June 30, 2021 , it is expected that the system will begin to provide flood mitigation benefits by the end of 2020. The estimate of probable cost for Upper Bee Branch Creek Railroad Culverts Project is as follows: BID Construction $25,900,000.00 Contingency (�5°k) 1 ,279,149.00 Property Acquisitions 410,000.00 Engineering 3,596,200.00 Total Project Cost $31,185,349.00 The proposed project funding is summarized as follows: Funding Source Amount HUD CDBG NDR Grant $12,559,703 U.S. EPA Clean Water SRF Loan 16,300,000 State Sales Tax Increment Funding 1 ,279,149 State Sales Tax Increment Bond 1 ,046,497 Total $31 ,185,349 City Engineer Gus Psihoyos recommends adoption of the attached resolution awarding the construction contract for the Upper Bee Branch Creek Railroad Culverts Project to Tricon General Construction, Inc. in the base bid amount of$25,900,000.00 and modifying the construction schedule of improvements associated with the Bee Branch Watershed Flood Mitigation Plan outlined herein so that awarding the contract for the Upper Bee Branch Creek Railroad Culverts Project can be done without increasing planned debt and without increasing previously adopted Stormwater Utility rates. 5 I concur with the recommendation and respectfully request Mayor and City Council approval. 1 j t.11��'GL+'t tf t� , Mic ael C.

BACKGROUND Since 1999 there has been six Presidential Disaster Declarations which included the Bee Branch Creek Watershed. The Drainage Basin Master Plan, completed and adopted by the City Council in 2001, established that there are more than 1,100 properties at risk of flood damage as a result of the flash flooding. Based on a subsequent study in 2009 by the Federal Emergency Management Agency (FEMA), there are 1,373 properties in the flood prone area. In addition to homes, there are over 70 businesses in the at-risk area with over $500 million in annual sales. The flood prone area in the Bee Branch Watershed encompasses historic neighborhoods offering some of the community's most affordable workforce housing. Most residents are working families, many are elderly -- those least likely to recover from repetitive flood loss. Repetitive flood damage leads to disinvestment; from 2004 to 2009, while commercial property values grew by 39% citywide, they fell by 6% in the Bee Branch Watershed flood prone area. Since 2001, the City has implemented many of the improvements outlined in the Drainage Basin Master Plan. But since 2001 several intense, storm events have occurred in the Dubuque metropolitan area so that revisiting the predicted hydrology and hydraulic behavior of the Bee Branch Watershed was appropriate. Over a twelve year period starting in 1999, there have been three 100-year storms, two 50-year storms, one 25-year storm, and one 10-year storm. Finally, it is important to consider how additional flood mitigation efforts undertaken by the City since 2001 fit with the overall effort to mitigate flooding. Therefore, work began to update/amend the Drainage Basin Master Plan. On November 18, 2013 the City Council passed Resolution 335-13 adopting the 2013 Drainage Basin Master Plan Amendmenfi. The 2013 Amendment did not replace the 2001 Drainage Basin Master Plan. Instead, it built upon its foundation. The amended Drainage Basin Master Plan outlined several improvements throughout the Bee Branch watershed to mitigate the effects of future flooding and disasters. Collectively, the improvements form the basis of the Bee Branch Watershed Flood Mitigation Project outlined in Table 1 below. Table 1.

Due to the contributions of local, state, and federal funding partners, Dubuque citizens will see a return on their investment of more than $8 for each $1 spent. The Bee Branch Watershed Flood Mitigation Project represents a multi - phased, fiscally responsible investment. It reflects a holistic approach to mitigate flooding as it will also improve water quality, stimulate investment, and enhance the quality of life of watershed residents. On December 4, 2013, the lowa Flood Mitigation Board voted to approve the City's use of$98,494,178 for the Bee Branch Watershed Flood Mitigation Project — a multiphased, fiscally responsible investment that reflects a holistic approach to mitigate flooding as it will also improve water quality, stimulate investment, and enhance the quality of life of watershed residents. The funding allows much of the protection to be provided over the next six years, instead of over the next 20 years (only some of the 240 alleys will take up to 20 years). On February 3, 2014 the City Council adopted Resolution 31-14 authorizing the execution of an agreement with the State of lowa Flood Mitigation Board and authorizing the City's use of sales tax increment funding for the Bee Branch Watershed Flood Mitigation Project. 2 On March 5, 2014 the City Council passed Ordinance 16-14 establishing the stormwater utility fee rate structure necessary to fund the various phases and improvements associated with the Bee Branch Watershed Flood Mitigation Project. The result was that the lowering of rates previously established by Ordinance 21-12 in Fiscal Years 2015, 2016, 2017, 2018, 2019, 2020, and 2021. A comparison the current Stormwater Utility rates established via Ordinance 16-14 to the previously adopted rates established via Ordinance 21-12 are outlined in Table 2 below. Table 2. Comparison of the current Stormwater Utility rates established via Ordinance 16-14 to the previously adopted rates established via Ordinance 21-12. FY22 FY15 FY16 FY17 FY18 FY19 FY20 FY21 & Be ond Rates Per Ordinance $8.00 $8.50 $9.00 $9.00 $9.00 $9.00 $9.00 $9.00 21-12 Current Rates Per Ordinance $5.98 $6.38 $6.81 $7.27 $7.76 $8.29 $8.85 $9.00 16-14 In December of 2004, the City Council adopted the alignment for the Bee Branch Creek Restoration Project based on the work and recommendation of the Bee Branch Citizen Advisory Committee. The adopted alignment crossed the railroad yard at 506 GarField Avenue now owned by Canadian Pacific. In August of 2008, th� City Council authorized the hiring of Strand & Associates (Madison, WI), in association with IIW Engineers (Dubuque, IA) and Ken Saiki Design (Madison, WI), to prepare the final design of the Bee Branch Creek Restoration Project which included the section through the railroad property at 506 Garfield Ave. CP's January of 2015 response was considered a conditional approval of the design, citing four minor issues for the City to address. While the City was in a position to move forward negotiating a Construction Agreement with CP and possibly moving forward with the improvements through CP property, doing so would have delayed the upstream improvements such that the City risked the loss of$4 million in grant funding (EDA, IDOT, & RECAT). Therefore, the City proceeded with completing the Upper Bee Branch Creek project upstream of the railroad property. Completed through multiple contracts, again due to funding, the City proceeded with the construction of the Upper Bee Branch Creek Restoration Project. In May of 2015, the City Council adopted Resolution 176-15 awarding the contract for the Upper Bee Branch Creek— Channel, Streets, & Utilities Project. In May of 2015, the City Council adopted Resolution 177-15 awarding the contract for the Upper Bee Branch Creek— Structures Project. In October of 2015, the City Council adopted Resolution 351-15 awarding the contract for the Upper Bee Branch Creek Mississippi River Trail Project, the third contract associated with the Upper Bee Branch Creek Restoration Project. In 3 December of 2015, the City Council adopted Resolution 422-15 awarding the contract for the Bee Branch Creek Basin Overlook & 22nd Street Parking Lot Project, the fourth and final contract associated with the Upper Bee Branch Creek Restoration Project. The improvements were substantially complete by July of 2017. In January 2016, the State was awarded $95.7 million in HUD National Disaster Resiliency Competition grant funds. Per the award, the City of Dubuque is to receive $8.4 million for a comprehensive "Bee Branch Healthy Homes Resiliency Program" to help residents address residual impacts from the flooding experienced within the Bee Branch Watershed. The City is also to receive $23.1 million for storm water infrastructure improvements associated with the Bee Branch Watershed Flood Mitigation Project. The infrastructure improvements included the (Upper) Bee Branch Railroad Culvert Infrastructure Improvements through Canadian Pacific property at 506 GarField Ave. In October of 2016, the City Council adopted Resolution 362-16 authorizing the execution of a contract with the lowa Economic Development Authority (IEDA) in order for the City to utilize $23,293,253.00 in HUD National Disaster Resiliency Competition grant funds for the Bee Branch Watershed Flood Mitigation Project with $9,000,000 specifically for the proposed culverts from the Lower Bee Branch Creek, through Canadian Pacific Railway property, to the Upper Bee Branch north of Garfield Avenue. This phase of the Bee Branch Creek Restoration Project is also referred to as the Bee Branch Railroad Culvert Infrastructure Improvements Project. The contract with IEDA requires that the City complete all of the improvements by June of 2021. In July of 2017, the City and CP executed the Amended and Substituted Service Agreement reflecting the current approach to install the tunneled culvert system and establishing a new expiration date of December 31, 2018. Under the terms of the original agreement, the City paid CP $100,499.56 for their reimbursable expenses. Per the amendment, both agreed that reimbursable expenses for CP services incurred after December 30, 2014 shall not exceed $50,000, unless agreed upon through a subsequent amendment. In December of 2018, the City Council adopted Resolution 385-18, authorizing the execution of a Construction Agreement and an Environmental Right of Access Agreement with Canadian Pacific Railway. The Upper Bee Branch Creek Railroad Culverts Project (Project) represents the final contract associated with the Bee Branch Creek Restoration Project (Phase 4 & 7 of the Bee Branch Watershed Flood Mitigation Project). The improvements will allow for the efficient flow of floodwaters from the recently completed upper Bee Branch Creek improvements, through the railroad yard on GarField Avenue, to the lower Bee Branch Creek. Project elements include the installation of six, 8-foot diameter culverts under the railroad tracks using tunneling methods. This allows for the railroad operation to 4 continue unimpeded during the construction project. In addition to the culverts under the railroad tracks, the Project includes the extension of the box culverts installed under Garfield Avenue as part of the upper Bee Branch Creek improvements to a new buried junction chamber, or transition structure where the flow from the upper Bee Branch Creek will join with flow from the Bee Branch storm sewer from Pine Street. The combined flow will then flow under the railroad tracks through the tunneled pipes mentioned previously into the lower Bee Branch Creek. An outfall structure will be constructed where the water will flow into the lower Bee Branch Creek. This will include a headwall for the culverts, a flood gate with pump statior� to control the depth of water in the upper Bee Branch Creek, topped by a concrete pad that will allow access to the culverts and gate from above while also providing a plaza area for citizens to overlook the lower Bee Branch Creek. The Project also incorporates the existing box culverts underneath the railroad tracks into the flood control system. The design will allow the existing box culverts to serve dual functions: flood control and as a hike/bike path under the railroad tracks. In addition to the improvements identified above, the Project is being bid with four "additive" alternative bid items that could be awarded based on the availability of City funds. The alternative bid items are as follows: While the base bid includes the establishment of a minimum Bid Alternate 1 amount of landscaping and vegetation, this bid alternative includes Additional Landscaping additional planters, a mulch path along the west side of the Bee and Amenities Branch to 16th Street, additional bike racks, benches, where the new cutverts will discharge into the Bee Branch Creek. The site furnishings include shade structures and enhanced, Bid Alternate 2 architectural seating areas that would help create a sense of place Site Furnishings at the new plaza area that will overlook the lower Bee Branch Creek. Bid Alternate 3 The trail and tunnel modifications involve the construction of the Trail and Additional hike/bike trail such as the paving the trail, improvements to the box Tunnel Modifications culverts to make them suitable for a trail, and adding tunnel lighting and cameras. This involves the installation of a 36-inch diameter sanitary sewer from the lower Bee Branch Creek to the sewer on GarField Avenue Bid Alternative 4 installed as part of the upper Bee Branch Creek construction Sanitary Sewer project. Currently, the flow from the existing sanitary sewer flows Interceptor under the box culverts on Garfield Avenue through a siphon. Construction of the new sewer will allow the City to eliminate the need for a siphon. DISCUSSION On February 5, 2019, the City received five bids for the Upper Bee Branch Creek Railroad Culverts Project. Tricon General Construction, Inc of Dubuque, lowa submitted the low base bid of$25,900,000.00, which is 1.24% over the engineer's estimate. In addition to the base bid, there were alternate bid items. A summary of the bid proposals received is as follows: 5 Contractor Name Base Bid gase Bici with Alternates Tricon General Construction, Inc of Dubuque, IA $25,900,000.00 $28,483,000.00 Portzen Construction, Inc. of Dubuque, IA 26,374,000.00 29,269,100.00 Langman Construction, Inc of Rock Island, IL 27,587,000.00 29,385,000.00 Michels Corporation of Milwaukee, WI 41,383,287.00 45,800,795.00 Super Excavators, Inc of Menomonee, WI 45,290,000.00 49,120,000.00 ENGINEER'S ESTIMATE $25,582,982.00 $28,911,473.00 In conjunction with the preparation of the Fiscal Year 2020 Budget, the funding plan and schedule of the various phases of Bee Branch Watershed Flood Mitigation Project were considered. The construction contract budget for the Upper Bee Branch Creek Railroad Culverts Project was set to match the engineer's base bid estimate of $25,582,982.00. The construction contingency budget to be used to cover unexpected work that might arise during construction was set to be $1,279,149.00 (5°/o of the construction contract budget). Because the low base bid received is 1.24% (or$317,018.00) more than the proposed budget, there isn't funding within the budget to do the additional work outlined in the alternate bid items. But as the project proceeds toward completion, and the need for the contingency funding is better understood, it may be possible to re-bid the alternate bid item improvements and construct them with contingency savings. The City will also continue to look for grant funding assistance to help cover the cost of the alternate bid item improvements. In order to award the base bid construction contract and cover the $317,018.00 shortfall, the recommendation is to adjust the funding and schedule of other phases of the overall Bee Branch Watershed Flood Mitigation Project versus increasing the planned debt for the project or increasing previously adopted stormwater utility rates. The proposed schedule is shown in Table 3 below. Table 3.

RECOMMENDATION I recommend that the City Council award the construction contract for the Upper Bee Branch Creek Railroad Culverts Project to Tricon General Construction, Inc. in the amount of the base bid of $25,900,000.00. BUDGETIMPACT The recommendation outlines a plan that will allow the contract to be awarded and the project to proceed without increasing planned debt for the project and without increasing previously adopted stormwater utility rates. The recommendation will, however, require the rescheduling other phases of the overall Bee Branch Watershed Flood Mitigation Project because it includes shifting funding for other phases of the overall watershed project to this phase.
