County Zoning CommIttee spproached towns and asked if development patterns on bluffiands were an issue, and if so, what the county should do. C. Two townshIps finn1y stated they were not Interested in state legislation on the issue and that the county should look at the issue. D. This lellil. to a number of meetings with citizens of the area and local government units from 1991 through mid-1993. E.

Defined purpose of the code. 1. BasIcally, the purpose of the Bluffiand Code is somewhat the same as the Shoreland Code. Both. codes are Intended to preserve natural aesthetics of an area. 2. The Bluffiand Code also controls the placement of structures and confllctlnlt land uses by settlnlt minimum lot sizes and widths, estabUshlng allowable uses of land. and setbacks of buildings. 3. In additIon to definIng lot size and setbacks, the Bluffiand Code protects the unique aesthetIcs of the bluffs by restricting removal of woody vegetation and controlling excavatIon. B. General Provisions 1. Jurisdiction of the code is listed by township, section, then by forty (40). 2. Dimensions of building sites - 5 acres minimum lot size wIth 300 feet of frontage required, and there is language for substandard lots. 3. Division of districts. a. BLUFF AREA - within the Usted forty (40), slopes greater than 30% and sloping toward Lake Pepin. This is a very restricted area. BLUFF2.DOC B:IMSOFFICE\ WiNWORD 2 11/17/98 b. BLUFFTOP SETBACK AREA - Area which lies between the blumine (line connecting slopea greater than 30%1 and forty feet back. Uses allowed: small, low decks; agriculture, etc. c. BUILDABLE BLUFFTOP AREA - area forty feet back from bluffiine and extending 460 feet inland. Uses allowed: Single Family ResideZJce-height restrictioZJs of 32 feet, eartb./summer vegetatioZJ tOZJes. d. TOE SLOPE AREA - Area within 100 feet of toe slope of bluff with slopes greater than 30%. Uses allowed: COZJditioZJaJ use SiZJgle Family ResideZJces. NOTE: Code than has significant language defining each area in detail. e. GENERAL ZONING PROVISION - Permit require- ments, administrative provisions, condition use. f. VEGETATIVE CUTTING PROVISIONS - No more than 20 feet in 150 feet. g. NONCONFORMING USES - existing structures allowed additions up to 50% of current fair market value as long as addition does not encroach further upon bluffs. 3. ADOPTION. The code was adopted by Pepin County in June, 1993. The townships of Stockhom and Pepin (both along Lake Pepin) adopted the code the same year. 4. EFFECTS OF THE CODE. A. Decks B. New developments - property owner awu'eness. BLlIFF2.DOC B :\MSOfFICE\ WlNWORD 3 11/17/98 -.,...:.

Bluffline setback lines are lines established parallel to and inland from a specified distance from a bluffline. (a) Setback Line Established. Unless a lesser distance of separation between a bluffline and its parallel setback line is ordered undersubpars. 1. or 2. below, the bluff- line setback line shall be located 40' from a bluffline. 1. Following review of a variance application requesting such changes, the ?card of Adjustment may direct that a reduced setback distance be applied to a parcel. In no case, ho\l\1ever, may the setback be reduced to less than 20' from the bluffline. Reductions for preexisting parcels shall be governed by ~ 19.03(2). Reductions for other parcels may be ordered only upon findings by the Board of Adjustment that: a. To maintain the standard 40 foot setback will produce severe hardship because of unique physical characteristics of the land. b. Construction which would be allowed because of the reduced setback will be no more visually conspicuous as viewed from the water edge 200 yards from the ordinary high watermark under summer vegetative conditions than would a building constructed in compliance with the 40 foot standard setback. c. Structures allowed to be located closer than the ;40 foot standards setback shall not .exceed one story in height. Reductions in setbacks ordered under the above procedure shall be the minimum amount needed to overcome the hardship if such hardship can be reduced consistent with par. (b) and in no case shall the setback be less than 20' from the bluffline. (b) Establishin~ Bluffline Setback Lines for Areas With Notched Bluffs. Coves and Other Unusual Land Forms. Certain areas within the Mississippi River Bluffline have unusual land forms which are not appropriate to the strict application of the above standards. In areas within this district in which there are notched bluffs, coves, inlets or other similar land forms involving bluffs descending to or near the high water elevation of the Mississippi River but in directions not parallel to the direction of flow of the Mississippi River, an artificial bluffline shall be allowed to be established by the Zoning Administrator. Persons desiring to challenge the Hnes so established may appeal the PEPIN COUNTY 01/01/94 MISSISSIPPI RIVER BLUFFLAND ZONING CODE 19.05(5)(b)1. determination to the Board of Adjustment, which shall hear the matter under its rules and bylaws and affirm, modify or reject the determination of the Zoning Administrator. Deci- sions by the Zoning Administrator and the Board of Adjustment on such an artificial1ine shall be based upon the following standards: 1. An artificial bluffline may be established only where use of the bluffline definition provided in sub,. (3) would result in buildings being required to be set back far more than is necessary to achieve the purposes of the district. 2. Artificial blufflines shall be placed in such a way as to result in a bluffline setback line that will ensure that construction inland thereof will be no more visually , conspicuous or capable of erosion or subject to the hazards than would construction that is allowable on nearby lands having unusual land forms; and, 3. In no case shall an artificial bluffline be established in a manner which would result in greater restrictions being imposed upon land usage than would application of the standard bluffline.

Buildable bluff top areas are areas within the district which are not within the bluff areas or the bluffline setback areas. These areas are characterized as "buildable" in the sense that they are outside of the 2 landform areas (bluff and bluffline setback areas) which are subject to special provisions by terms of this chapter. A buildable bluff top area will be truly eligible for new construction only if it meets all terms of this chapter and other County and local ordinances. The buildable blufftop area shall extend 460' inland from the bluffline setback area. Beyond the limits of the buildable blufftop area the provisions of this chapter shall not apply. PEPIN COUNTY 01101194 MISSISSIPPI RIVER BLUFFLAND ZONING CODE 19.05(7) (7) TOE SLOPE AREA DEFINED.

(Ordinance 99-9 3-8-99) iO 1999 Village of Lake Bluff. All Rights Reserved. Overview Critical Area Program/ Mississippi National River and Recreation Area Denmark is one of twenty-five communities within a 72-mile Mississippi River corridor through the Twin Cities metropolitan area. In 1976, a Governor's Executive Order established this corridor as a "Critical Area". This required, per the Critical Areas Act of 1973, that communities develop plans to protect the historic, cultural, aesthetic, and natural qualities of the river. The Department of Natural Resources (DNR) now reviews and approves these Critical Area Plans and ordinances, which contain mandatory elements, referred to as Tier I elements. The extent of the Critical Area in Denmark Township is illustrated in Figure 1. The following are general purposes of the Critical Area Program: ~ Protect and preserve unique and valuable state and regional resources. ~ Prevent and mitigate irreversible damage to these resources. ~ Preserve and enhance natural, aesthetic, cultural and historic value for the public use. ~ Protect and preserve the river as an essential element in the national, state and regional transportation, sewer and water and recreational systems. ~ Protect and preserve the biological and ecological functions of the corridor. The United States Congress designated this same corridor as the Mississippi National River and Recreation Area (MNRRA) in 1988. The intent of this legislation was to enhance the resources of the metropolitan river corridor, develop overall policies for the management of lands and water within the corridot, and increase regulatory consistency. These policies are contained in the MNRRA Comprehensive Management Plan (CMP), which was developed by the Mississippi River Coordinating Commission and National Park Service, in consultation with local and state units of government. The CMP incorporates policies and planning elements that are recommended for local jurisdictions (teferred to as Tier II elements) but which remain voluntary. The National Park service is the body responsible for local implementation of the CMP. It has no review or regulatory authority ovet local plans and ordinances, but can recommend funding for implementation plans in communities that incorporate the CMP. The following are general purposes of the MNRRA Program: ./ Preservation and enhancement of environmental values. ~ Enhanced outdoor recreation opportunities. ~ Conservation and ptotection of scenic, historical, cultural, natural and scientific values. ~ Commercial use consistent with purpose of designation. The Minnesota State Legislatute amended the 1976 Land Planning Act in 1995 to require that communities amend their comprehensive plans every ten years. Initial updates are due by the end of 1998. The Metropolitan Council, the DNR and the National Park Service coordinated efforts to provide technical assistance to communities that are updating their plans to meet mandatory Critical Area planning requirements, as well as encouraging communities to address the voluntary elements of the MNRRA Comprehensive Management Plan. 36 State law requires communities to complete Critical Area Plans as well as ordinances that are consistent with the Plan. The Township must submit the Plan to the Metropolitan Council for review. The Township must also submit the Plan and ordinances to the DNR, for review and approval, based upon consistency with elements of Executive Order 79-19, the Critical Areas Act of 1973 (Minnesota Statute 116G) and related state laws. The MNRRA CMF is broad and intended to address a variety of different river corridor issues. The CMP contains elements that go beyond what is required under State law. There is additional emphasis on public access to the river, historic preservation, and habitat restoration/ mitigation. Critical Area Goals The following are goals of Denmark Township regarding the future use, preservation and enjoyment of the Mississippi River Critical Area. These goals have also been incorporated into the Comprehensive Plan. ./ Protect the rural character of tbe Township through growth management strategies. ./ Protect and preserve the St. Croix River corridor and the Mississippi National River and Recreation Area. ./ Preserve the open space, scenic and natural qualities of the Critical Area, as well as its ecological and economic funcrions. ./ Establish land use patterns that preserve and protect the natural qualities and existing character of the landscape. ./ Protect environmental systems from harm. ./ Maintain and enhance the natural amenities of the Township, including wildlife habitat. ./ Protect surface waters and weiland areas to protect natural habitats, ground water quality and aesthetic qualities. ./ Provide recreational opportunities for all residents of the Township. ./ Enhance park and recreation areas of the Township. Critical Area Policies These policies reflect Denmark's specific commitments to the preservation and management of the Critical Area. Land Use ./ Allow residential densities to be at levels consistent with the character of existing development. ./ Encourage the clustering of residential uses, provided that the clusters meet open space and environmental preservation criteria, as well as other criteria outlined in the Township's zoning,..."j subdivision and Critical Area ordinances. ./ Enforce mandatory river corridor development standards for the St. Croix and Mississippi River corridors. ./ Prevent commercial or industrial uses from negarively impacting residential uses or the river corridor areas. ./ Prohibit mineral extraction uses in tbe Critical Area. ./ Apply setback and height restrictions and encourage careful site design to maintain the natural view of the river corridors from existing open space and developed areas and from the river. 38 V' Protect and preserve natural, historic and cultural resources where possible.

V' Enforce development standards consistent with the Wetlands Conservation Act. V' Encourage the restoration of degraded wetlands where practical. V' Ensure implementation of Chapter 4 of the Washington County Development Code, which governs the permitting, design, installation, expansion, and maintenance of individual sewage treatment systems. V' Ensure implementation of Chapters 5 and 6 of the Washington County Development Code, which governs the management of bluffland and shoreland areas in the Township. V' Ensure implementation of sections of Chapter 3 of the Washington County Development Code that reference stormwater management, including the MPCA's publication "Protecting Water Quality in Urban Areas" to minimize rates and volumes of runoff and to improve water quality. V' Ensure implementation of sections of Chapter 3 of the Washington County Development Code that incorporate recommended erosion and sedimentation control practices of the Washington County Soil and Water Conservation District and the Lower St. Croix Watershed Management Organization (WMO). V' Participate in and implement the plans of the Lower St. Croix Watershed Management Organization (WMO). V' Require the preservation and restoration of native vegetation in areas not used for agricultural purposes when possible to protect wildlife habitat, bluffs and floodplain forests. 39 Park, Recreation and Open Space ./ Require the dedication of park or open space land, or cash in lieu of land, in conjunction with the subdivision of all properties. ./ Accept land gifts or require land dedications in areas with potential open space, natural feature or habitat qualities. ./ Encourage the preservation or restoration of habitat and biological diversity. ./ Identify potential trail corridors that provide connections to and views of the river. ./ Encourage developers to provide trails and access to public trails. ./ Protect stream banks from recreational impacts. Critical Area Guidelines The following are guidelines, rather than policies, that the Township will encourage homeowners and land developers to observe when conducting activities that disturb land within the Critical Area. Most of these guidelines are more or less incorporated into existing ordinances. However, the Planning Commission should refer to these guidelines when exercising review authority regarding permits and plans for site development. Vegetation ./ Removal of healthy, non-hazardous vegetation is discouraged, particularly along shoreline, bluff face, in werlands, and on floodplains. ./ Native plant materials should be used in replanting. ./ Vegetation removal is only appropriate in building and paved areas. ./ Grading should preserve root aeration zone and stability of existing trees. It should also provide adequate watering area equal to at least 50% of crown area. Fencing should be used to ensure this. ./ Vegetation could be selectively pruned to improve river views and vistas, but not alter the character or massing of vegetation. ./ Large areas of bluegrass should be avoided in order to maintain natural appearance, control pollution and conserve water. Erosion and Sedimentation Control ./ Development should be suited to site, soil conditions and existing drainage patterns. ./ Minimize runoff rates and maximize absorption of water. ./ Natural erosion control is preferable over structural. ./ Erosion and sediment control should take place prior, during and after site construction. ./ Preserve quality of surface water runoff and ground water recharge. ./ Fill should be stabilized with plant material and not exceed 4: 1 slope. ./ Werlands and other water bodies should not be used as sediment traps. ./ Detention ponds for temporary water storage should be used when practical. ./ Natural slopes and vegetation are preferable to retaining walls, but when necessary, walls should be no higher than 5 feet and be constructed of wood or natural stone. If walls are terraced, space between terraces should be at least 15 feet and heavily planted. 40 Intergovernmental Cooperation The Comprehensive Plan and Mississippi River Critical Area Plan were created in consultation and negotiation with a variety of levels of government and government agencies. Denmark Township recognizes that the planning process does not end at the Township's borders and that there are opportunities and concerns that go beyond the local level. Denmark is part of a County, a state, a metropolitan region, a watershed, and is among many communities that share the river corridor area for a variety of uses. Denmark recognizes its responsibility to participate in the protection of not only local resources, but resources of county, state, regional or national significance. Denmark Township must comply with a variety of statutory obligations that impact the natural and built environment in the Township. These include Critical Area requirements; Metropolitan Land Planning Act requirements; County land use planning requirements; shoreland, floodplain and wetland regulations; and other requirements. Meeting planning goals at the local, county, and regional level often requires participation by multiple levels of government. These include, among others, the DNR, the Metropolitan Council, and Washington County. The Township supports the spirit of many of the plans, programs, policies, and obligations that impact the community. The Township is also committed to voicing concerns when it feels that plans and regulations are unnecessarily strict, cumbersome or do not adequately meet the interests of local residents. Land Use and Natural Features The Mississippi River Critical Area in Denmark constitutes approximately 1,250 acres. Much of this area consists of important natural features, including bluffland, shoreland, wetlands and floodplain. Table 1 below provides a breakdown of land uses in Denmark's Critical Area. Table 1 MNRRAjCritical Area Land Uses Commercia! Developed Ruidential Water/ slopes/floodplain Vaeon! agricultural Vacant Sinj!.Ie~Famify Estate TOTAL 20 152 524 105 449 1,250 % 1.6% 12.2% 41.9% 8.4% 35.9% 100.0% acres SOHftt: Denmark T01PflShip Zoning and Other Ordinances Affecting Land Use Most of the land is zoned Single-Family Estate, or one home per three acres. Portions of the Critical Area are zoned A-2 (Agriculture), or one home per twenty acres. A small portion of Denmark's Commercial/Industrial Area lies within the Critical Area boundary. Much of the Critical Area cannot be developed, however, due to the presence of floodplain and steep slopes near the river. A portion of the Critical Area is also within Washington County' Shoreland Overlay Zoning Dis trict. Land uses that are inconsistent with existing regulations may continue, provided they meet all other applicable regulations and do not pose immediate risks to the public health, safety and welfare. 41 There is at least one non-conforming use in the Critical Area. Both the Denmark Township Zoning Ordinance and Denmark Township Mississippi River Corridor Ordinance will govern any non- conforming uses in the Critical Area. The Mississippi River Corridor Ordinance contains provisions that prohibit the continuance of a non-conforming use is such activity ceases for an extended period of time or if a majority of the facility is damaged. Current requirements identify a period of six months after which a non-conforming use will no longer be allowed to continue. The Ordinance also stipulates that if more than half of the facility's market value is destroyed, then the use must also cease to continue. Native Vegetation The Department of Natural Resources Biological Survey provides important information about remaining native and undisturbed plant "communities" in the County. In the most downstream portion of the Critical Area, there is a peninsula in the river, just to the south of Conley Lake. This area is seasonally flooded by the Mississippi River and contains a relatively undisturbed Silver Maple Floodplain Forest. The forest canopy is dominated by silver maples with occasional canopy trees such as green ash, black ash, American elm, slippery elm and hackberry. Upstream, associated with a ravine area, lies a relatively undisturbed area that includes Maple Basswood Forest, Oak Forest, and communities of plants growing from moist, moss-covered rock walls (typically ferns). Along the river lies Dry Bedrock-Bluff Prairie, where mostly bluestem, side- oats grama, and satin grasses cover shallow soils over bedrock. 42 Preservation Plan Several ordinances control the density and character of any development in the Critical Area. These include Township's Zoning Ordinance and Chapters of the Washington County Development Code that address zoning, subdivision standards, shoreland management, floodplain management, and werland regulations. In addition, the Township will maintain a Mississippi River Corridor Ordinance. New performance standards will be consistent with Executive Order 79-19 and will incorporate most Tier II guidelines contained in the MNRRA Comprehensive Management Plan. Among a variety of land disturbing activities that will require the input of the DNR, the Township will also solicit the input of the DNR when a proposed land disturbing activity may impact a natural community or sites of rare species. Residential Density Standard Denmark's portion of the Critical Area is within a "Rural Open Space District", as defined by the Governor's Executive Order 79-19. The intent of this district is to preserve the open, scenic and natural characteristics of the area, as well as the ecological and economic functions of the corridor. The interim regulations contained in the Executive Order stipulate a maximum density of five acres, but the DNR has deferred to the Council the authority to establish density standards for the corridor. The Metropolitan Council uses its Regional Blueprint Policy Areas as a standard. The density inconsistency between the Metropolitan Council's Regional Blueprint and the Council- approved Washington County Comprehensive Plan was explained previously in the Comprehensive Plan. Denmark Township will retain its Single-Family Estate density standard of one home per three acres, which has been in effect for twenty years, which is more restrictive than the County's density standard, and which the Township believes is not in conflict with the goal of preserving open space, scenic resources, and ecological functions in the Critical Area. Table 2 MNRRA/ Critical Area Residential Development Potential and Net Density Commercial Developed Residential Water/slopes/floodplain Vaeanl agricultural Vacant SinJ'./e-Famify Estate TOTAL 20 152 524 105 449 1,250 residential density n/a n/a n/a 120 1:3 potential new units o o o 5 150 155 acres Total undeveloped acreage 1,078 Divided by potential new units 155 Equals net density 6.95 Source: Dmmark TOlJlmhip As noted in Table 2 and illustrated on Figure 1, a portion of the Critical Area is also designated Long-Term Agriculture. The density permitted in this area is limited to one home per twenty acres. There are also over 500 acres of undevelopable area within the corridor, consisting of floodplain, steep slopes and the river itself. When the undevelopable area is included in the density analysis for 43 potential remaining development in the Single-Family Estate and Long-Term Agricultural districts, the net maximum density for residential development is one home per seven acres. Denmark Township proposes to evaluate and establish new residential development alternatives, which may include flexible lot size standards and open space development performance standards. The purpose of the alternative regulations will be to enhance and preserve natural features in the river corridor while maintaining existing development rights. The Township may also create incentives or development bonuses to encourage the use of preservation techniques. Building Scale and Context: Dimensional Requirements A particular concern about development in the Critical Area is related to the scale of buildings and their relationship to the natural landscape. Tbe scale, height and mass of buildings are regulated through the zoning ordinance, subdivision ordinance, and requirements of County Shoreland Management Regulations. The low-density character of the area resolves many of the issues related to "context" and "scale". In some cases, clustered development may be appropriate in order to preserve special natural features. This is possible through the existing zoning and subdivision ordinances. Maintaining the quality and character of the Critical Area includes protecting sensitive shoreline and bluff areas by regulating the proximity of structures to either the shoreline or bluffline and limiting the visibility of structures from the river. Denmark Township will utilize its Mississippi River Corridor Ordinance to govern specific dimensional requirements for the entire Critical Area. With regard to the placement of structures, the ordinance specifies minimum structure and road setbacks from the ordinary high water level and bluffline (200 feet and 100 feet, respectively) as well as a maximum structure height (35 feet). These standards meet Tier II planning guidelines. Denmark Township will also utilize the Washington County Shoreland Management Ordinance and Zoning Ordinance to protect the shoreline and shoreland area. These requirements include minimum lot width at the shoreline and setback line (currendy both 250 feet). The ordinance also mandates a maximum impervious surface of 25%. Although the Shoreland District is smaller than the Critical Area, the application of its standards will further protect an important portion of the Critical Area. The disruption or change in the topography of the Critical Area is also addressed in the Critical Area Ordinance. The Ordinance stipulates that no grading, filling, or excavating can be conducted in the Critical Area without first obtaining a permit (except in cases where the grading, filling or excavating is the minimum required for a building site and utilities.) All grading and filling activities requiring a permit must comply with the site planning standards in Section 3 of the Denmark Township Mississippi River Corridor Ordinance. Bluff Preservation Denmark Township recognizes that preservation of bluff areas is crucial to maintain a natural appearance along the corridor. Critical Area Ordinance regulations require that structures must be set back 100 feet from the bluff line, as suggested by Tier II planning guidelines. In addition, the Critical Area Ordinance regulates the cutting of vegetation on the slope or face of bluffs and within the area 40 feet landward from bluff-lines. These provisions are consistent with Tier II Critical Area planning guidelines. 44 The preservation of Bluff areas will be further accomplished by enforcement of the Washington County Shoreland and Zoning Ordinances, which also addresses grading of the land. The Shoreland Ordinance prohibits grading or filling within 20' of the bluffline (Bluff Impact Zone) or within 100' of the shoreline (Shore Impact Zone, or half the structure setback from the shoreline). Part 3 of Chapter 2 of the Washington County Development Code addresses requirements for 'Land Alteration and Grading'. In order to prevent erosion and protect viewsheds, the Township embraces Tier II guidelines that suggest that bluff slopes over 12% be left undisturbed. The Denmark Township Mississippi River Corridor Ordinance will prohibit development on slopes over 18%. The ordinance permits . development on slopes between 12% and 18% only if a variety of performance standards are met, including those that address safety, the impact on views from the river, and the installation of individual sewage treatment systems (which cannot be placed on slopes greater than 12%). Performance standards in the County Zoning regulations (part 3 of Chapter 2 of the Washington County Development Code) also stipulate a more thorough review of plans for development on slopes that are 13% or more. The Township will also seek the review and input of the Department of Natural Resources for development proposals on land that exceeds 12% slope. Shoreline Preservation The preservation of the shoreline area is an important aspect of the Critical Area Plan and an important aspect in maintaining the quality and character of the corridor. In particular, the shoreline area is a corridor for wildlife movement; and stable vegetation along the shoreline prevents erosion and preserves river water quality. This portion of the Critical Area is also the most sensitive to the visual impacts of development. The preservation of the Shoreline is accomplished with many. of the requirements described above that address lot width, structure and road setbacks and amount of impervious surface. Other requirements include the preservation of vegetation in the corridor. Specifically, the Denmark Township Mississippi River Corridor Ordinance requires that any structure be setback 200 feet from the ordinary high water mark. This meets both Tier I and Tier II standards. As per Tier II guidelines, existing sign regulations would not allow a sign within 100' of the shoreline; and commercial signage will not be placed within any residential disrtict. The County Shoreland Regulations require that no trees over 6 inches in diameter be cut within the designated 200' setback area and that natural vegetation be maintained insofar as feasible. Additional measures to preserve vegetation in the Critical Area are described below. Opportunities for trail connections and public access to shoreline areas may be limited in Denmark, but the Township will consider any land dedication opportunities that may arise through the residential subdivision process. Vegetation Preservation Vegetation is an essential part of the Mississippi River Critical Area. It preservation is important to landowners, visitors to tbe area, and recreational users of the Mississippi River. The value of vegetation can be measured in terms of economic benefit, the quality of habitat, hydrological function or recreational appeal. The preservation of vegetation in the Critical Area involves ongoing management as well as requirements at the time of the site development process. Regulating the cutting of vegetative areas within the Critical Area is the most important strategy in preserving a contiguous vegetative cover along the river. Regulations should be the strictest in bluff areas, where development could have the most pronounced impact on erosion and views. The Denmark Critical Area Ordinance regulates the cutting of vegetation on the slope or face of bluffs 45 and within the area 40 feet landward from bluff-lines. Cutting is allowed in other areas, provided that the areas are kept to a minimum size, blended with the natural terrain, and done so as to maintain the aesthetic value of the area and not result in risk of erosion. Tree cutting in the Shoreland District requires a permit from the County. Landowners should, consistent with applicable ordinances, retain the right to control aspects of vegetation management on their own property. Careful site planning is necessary to maintain the quality of the corridor as development occurs. Among other site plan content requirements, applicants for development pennits should demonstrate that all grading will be conducted in a manner that preserves existing trees. Both the Critical Area Ordinance and the County Shoreland Ordinance address the use of natural vegetation for the control of surface water drainage and limit the amount of impervious surface area. The Shoreland Management Ordinance states that a maximum of 25% of the lot may be covered with impervious surface. In order to retard surface water run-off and erosion, both the Shoreland Management Ordinance and the Critical Area Ordinance require that existing vegetation be restored after construction insofar as feasible. Erosion and Sedimentation Control Tier II guidelines are more specific than Tier I guidelines with regard to erosion control, but are essentially implemented within existing County and Township ordinances. Stormwater management standards are contained in Chapter 2, Part 3, Section 1.6 of the Washington County Development Code (Zoning Ordinance), Section 10.3 of the Washington County Subdivision Ordinance, and Section 738 of the Township Zoning Ordinance. Commercial Navigation/Industry Surface waters of the Mississippi River and St. Croix Rivers are primarily used for pleasure boating, although a significant amount of barge traffic occurs on the Mississippi River. The Mississippi is rather narrow as it passes through the Township, which would limit potential use for barge fleeting. The close presence of King's Cove Marina would also result in a conflict between recreational and commercial uses. In addition, opportunities for river related industries are limited due to the absence of developable land at the river. With exception of the railroad corridors at the river's edge, land near the river is either within the Mississippi River floodplain or part of the river bluff. A commercial boating marina is located within the City of Hastings, immediately south of Denmark in the backwaters of the Mississippi River. Parks, Trails and Preservation Areas The opportunities for trail connections, new open spaces, and public access to the river may be limited in Denmark due to existing development, site constraints, existing railroads, and acquisition priorities of Washington County. However, the Township is committed to working with the County, State agencies, and the National Park Service to further explore the feasibility and desirability of public trails or access to bluff top areas in Denmark's Critical Area. The County Plan references the MNRRA program and the possibilities for funding facilities under the MNRRA Comprehensive Management Plan. The railroads along the river, if ever abandoned, could become 46 important trail connections in the Critical Area. The Township will consider this and other potential trail connections in the corridor. The Parks, Trails and Open Spaces section of the Comprehensive Plan describes in detail opportunities for improvements to parks, trails and open space resources, including the possibility of connecting the Washington Parkway with the Dakota County Regional Trail. The Township will work cooperatively with Washington County and the Minnesota Department of Transportation in identifying opportunities for scenic overlooks, dedicated open space or recreational resources. Opportunities for passive recreational or trail uses in floodplain areas on the east shore of the Mississippi River are more likely in the portion of the Critical Area that falls within Hastings. Areas that could be pertnanendy preserved are identified on Error! Reference source not found. and Figure 1. Features include areas of undevelopable steep slope and bluff top areas, natural community and rare species sites, and wedands. These preservation areas could be part of either public or privately owned preservation areas. "Steep slopes", as indicated on maps, generally represent areas where slopes may preclude development. Detailed survey maps are necessary, however, to precisely indicate areas where slopes exceed both 12% and 18%, as well as the true extent of other natural features. Transportation/Public Facilities The principal transportation and public facilities in Denmark's Critical Area include U.S. Highways 10 and 61 and two active railroads along the riverfront. There are no other public facilities proposed in the river corridor, including facilities that would involve river crossings. U.S. Highways 10 and 61 are under the jurisdiction of the Minnesota Department of Transportation (Mn/DOT). Mn/DOT should recognize the goals of the Critical Areas Act, the MNRRA Comprehensive Management Plan, and this document as it plans for and/ or improves these roadways. The Township will refer to this Plan when reviewing any public facility work by other levels of government. In planning and designing construction or reconstruction of all public transportation facilities, the Township will consider the inclusion of scenic overlook, safe pedestrian crossings and facilities along the corridor, and the reasonable use of land between the river and the transportation facility. New or modified transportation facilities should complement the planned land and water uses and not stimulate incompatible development. Parking areas in the Critical Area may be the most relevant concern for Denmark Township. Tier II guidelines specifically address parking facilities, all of which will be associated with residential uses within 300 feet of the river. The Shoreland Management Ordinance states that all new parking areas must be designed to take advantage of natural vegetation and topography to achieve maximum screening from public waters and minimize and control erosion. These measures should be consistent with field office technical guides of the local soil and water conservation district, or other applicable technical material. Parking areas must also meet setback requirements, currendy 200'. This does not apply to parking areas for watercraft access that meet vegetative screening and erosion control requirements of the ordinances. Critical area guidelines require new public or private roads to be set back 40 feet from the bluffline. 47 Implementation Program The implementation of the Comprehensive and Critical Area Plans does not end with adoption. The Township's official controls, such as the zoning ordinance and subdivision regulations, will ensure day to day monitoring and enforcement of the Plan. The regulatory provisions of these ordinances, as revised, will provide a means of managing development in the Township in a manner consistent with the Comprehensive Plan and Critical Area Plan. Official Controls As part of the planning process, the Township will evaluate irs land use controls and consider amendments to existing ordinances which eliminate inconsistencies with the Comprehensive Plan, enhance performance standards, protect public and private investments, conform to mandatory State and Federal regulations and make it an understandable document. The principal official controls used to implement the Comprehensive Plan include the following: ,/ Zoning Ordinance ,/ Mississippi River Corridor Ordinance ,/ Subdivision Ordinance (Chapter 3 oJWashington County Development Code) ,/ Shoreland Management Regulations (Chapter 6 oJWashington County Development Code) ,/ Floodplain Regulations (Chapter 9 oJWashington County Development Code) ,/ Lower St. Croix Bluffland and Shoreland Management Regulations (Chapter 5 oJWashington County Development Code) ,/ Individual Sewage Treatment System Regulations (Chapter4 oJWashington County Development Code) ,/ Mining Regulations (Chapter 7 oJWashington County Development Code) The plan identifies a number of specific changes to the ordinances that need to be considered by the Township. Some of these changes include: ,/ Implementation of a Mississippi River Critical Area Overlay Ordinance to ensure implementation of Tier I and Tier elements of the Critical Area Plan, including DNR notification requirements. ,/ Modification of residential district standards to provide flexibility in the layout of lots, as described in the plan. 49 .,/ Update of the surface water management plan upon completion of the Lower St. Croix Watershed Management Organizations' Second-Generation Watershed Management Plans. .,/ Amendments to the Township's subdivision regulations to better protect natural resources and amenities, and provide for appropriate land dedication and funding for improvement of the Township's park system. .,/ A review of the commercial district provisions to promote development, ensure appropriate use and regulation, and prevent land use or environmental incompatibility. Capital Improvements The Township does not have a formal capital improvement program, as capital expenditures are infrequent. The Township budgets for any capital improvements on an ongoing basis. The Township will annually review capital expenditures that may arise over a five-year period as a result of implementing the comprehensive plan. This may include public and private investments in infrastructure, park expenditures, infrastructure repair and replacement, building maintenance and repair, . and other planned capital expenditures. Like the Comprehensive Plan, the capital improvements planning process is ongoing and subject to modification, as appropriate. The preservation of natural resources in the Mississippi River Critical Area will likely occur through processes that tlo not depend on capital expenditures by the Township alone. Preservationwill result from the ongoing implementation of this and other plans. This includes ordinances that protect natural resources, land dedications through open space development; and the acquisition of trails, corridors, or'sensitive areas as a result of the planning and implementation of County and State agencies. . Plan Amendment Process The Comprehensive and Critical Area Plans are intended to be general and flexible; however, formal amendments to the Plan will be required when land us.e elements or growth policies are revised. Periodically, the Township should undertake a formal review. of the plan to determine if amendments are needed to address changing factors or events in the community. While a plan amendment can be initiated at any time, the Township should carefully consider the implications of the proposed changes before their adoption. When considering amendments to this plan, the Township will use the following procedure: .,/ Landowners, land developers, the Planning Commission or the Town Board may initiate amendments. .,/ Upon a request for an amendment the Town Board will review the amendment request and direct the staff or the planning consultant to prepare a thorough analysis of the proposed amendment. .,/ Staff or a planning consultant will present to the Planning Commission a report analyzing the proposed changes, including their findings and recommendations regarding the proposed plan amendment. The Planning Commission will make a recommendation to the board as to whether or not the Town Board should proceed with the plan amendment. 50 ,/ The Town Board will decide whether or not to proceed with the proposed amendment. If a decision is made to proceed, a formal public hearing will be held before the Planning Commission on the proposed amendment. ,/ Following the public hearing the Planning Commission will make a recommendation to the Town Board. ,/ The Town Board will receive the recommendation from the Planning Commission and make a final decision on whether to adopt the amendment. ,/ All amendments to the plan must be submitted to the Metropolitan Council (and DNR for Critical Area) for review prior to implementation. 51 Appendix A: Community 5 urvry and Results 52 r .

This overlay section shall apply to the Mississippi River Corridor district which is specifically delineated on the official Zoning Map of Dayton, and in Executive Order 79-19. This map shall be on file in the office of the City Clerk and shall be available for inspection and copying. a. Priority Areas. The Mississippi River Corridor contains three planning areas based on proximity and relationship to the river. The three priority areas are listed below. They are generalized areas as the location and setbacks vary based on topography and underlying zoning. Blufflines, as defined, may be found throughout each of the Priority Areas in the Corridor and are subject to setbacks. ~ w rr: .. ~ rr: o "' 0. 1 2 3 Mississippi Riwr 40' Bluflline Setback 100' OHW Setback Dayton RiwrRd. CrilicalArea Boundary 1. Area One (Bluff and Flood Plain) - Priority area number one is the area below the 40' bluffline setback and within the 100' Ordinary High Water Level (OHWL) setback (200' OHWL and 100' bluffline setback in the AG & SA zoning districts). This priority area shall be preserved to protect the natural, ecological, passive recreational and scenic properties of the corridor. New development, other than passive recreational uses, will not be allowed within Priority area one. 2. Area Two (Bluff top) - Area two is between the bluffline setback and Dayton River Road. Within this area, development will be reviewed on a case by case basis in order to protect the Corridor values, bluffs, floodplain and associated ravines and steep slopes and meet the standards of this Section. 3. Area Three (South River Road) - Priority area three is between Dayton River Road and the Corridor boundary. All development within area three shall also be reviewed on a case-by- case basis. In general, there will be more consideration for flexibility and allowance for density of development in area three than areas one and two because of the distance to the river and the dividing line of the road, if in accordance with protection of Corridor values and the standards of this Section.
