They would now like to sell this dwelling but maintain ownership of the horse arena. Therefore, they are requesting a minor subdivision. The total site is 50+ acres in size and Zoned Rural. T e area containing the dwelling is physically separated from the ba nce of the site, including the horse arena, by Hardwood Creek. Th Creek forms a natural barrier and is proposed as the new lot line. The newly created lot would be approximately 6 acres in size. A minimum of 10 acres is required according to the City Zoning, Ordinance for Rural Districts. The property owner is therefore requesting a variance in addition to the minor subdivision. Staff has reviewed the request and would recommend approval of the minor subdivision and variance for lot area. Hardwood Creek forms an obvious natural barrier and it would seem unreasonable to require the addition of 4 acres on the west side of the creek to this parcel. At this time the area west of the creek is used as pasture land for the horse arena and is not easily accessible to the property on the east side of the creek. Staff further believes any danger in setting a precedent concerning lot area is eliminated by the obvious physical characteristics of this site and the nature of Hardwood Creek. In summary we would recommend approval of the minor subdivision and variance request to allow a 6 acre +/- parcel in a Rural Zoning District with the following condition: 1. A Park Dedication fee in the amount of $550 be collected prior to recording of the minor subdivision with Anoka County. ............................... OPTIONSI 1.

Since the adoption of the 1981 Comprehensive Plan, the City has expanded its MUSA both in 1987 and 1990. However, changing development trends and new development regulations have significantly impacted the City's supply of available buildable MUSA land. The City growth rate during the 1990's has more than doubled over what was constructed in the 1980's. Additionally, the implementation of the 1991 Minnesota Wetland Conservation Act has significantly reduced both the supply of buildable land and development densities in the City's MUSA. Recognizing the constraints that confront the City's growth, Lino Lakes has prepared this Comprehensive Plan update to expand the City's 2000 MUSA and establish a land bank for the distribution of the MUSA within the City's development area. The plan amendment is intended to establish plans and policies that will serve as guidelines for managed growth through the year 2000. REGIONAL SETTING The City of Lino Lakes is located within southeastern Anoka County. The City is an outer ring suburb in the Minneapolis/St. Paul Twin Cities Metropolitan Area. According to the Metropolitan Regional Blueprint, Lino Lakes is at the edge between rural and urban service areas. In pursuing a MUSA expansion, the City must comply with the regional guidelines. and criteria for expanding urban service area. METROPOLITAN COUNCIL GUIDELINES The Metropolitan Council Blueprint identifies the following action steps that are applicable to urban service and rural service areas: Urban Service Area Action Step 3.A. The Metropolitan Council will provide regional services for urban -scale development within the urban service area,including the freestanding growth centers, consistent with local comprehensive plans that meet Metropolitan Council objectives for regional investments. The Metropolitan Council will provide only those services in the rural service area that do not promote urban development, except for services that meet a regional need as determined by the Metropolitan Council. Action Step 3.B. The Metropolitan Council will retain the current urban service area boundary, making appropriate changes after verifying land demand and supply with local governments along the boundary line. The Metropolitan Council will make changes in the current urban service area boundary consistent with regional policies, local plans to stage growth, aggregate land demand and supply within regional sectors and clusters of communities, and the capabilities of the regional systems. Action Step 3.E. The Metropolitan Council will give top priority for funds for regional systems to maintaining, upgrading and replacing system facilities serving existing urban development to make the best use of investments the region has already made. The Rural Service Area Action Step 3.G. The Metropolitan Council will not support extensive development in the rural service area. However, the Metropolitan Council will support low density residential developments at densities of no more than one unit per 10 acres, with a maximum of 64 units per 640 acre parcel (one square mile). It should not affect prime farmlands or areas certified or covenanted as part of the agricultural preserves program. Appropriate rural land uses must meet all environmental quality standards, not require urban -level support services, and be of a scale to serve local market demands. Action Steps 3.H. The Metropolitan Council will support agriculture as the primary long-term land use in the rural service area. The Metropolitan Council will give priority to the protection of those prime agriculture lands most capable of supporting long-term agriculture production, specifically "prime farmland" or Class I, II, III and irrigated Class IV soils. In a prime farmland area, the Council will support a density of one housing unit per 40 acres if the housing unit is part of a farming operation. Metropolitan Council MUSA Expansion Criteria In addition to aforementioned MUSA guidelines, the Regional Blueprint outlines specific criteria for increasing the size of an urban service. These criteria were used in the formulation of this Lino Lake Comprehensive Plan amendment. The City intends to demonstrate that its local objectives for land development are consistent with that of the Metropolitan Council. 2 Criteria for Increasing the Size of an Urban Service Area The Council will consider requests from local units for expansion to the urban service area. These requests will be considered together for their impact on the region as a whole, metropolitan systems, regional policy objectives and other units of govemment. Each request, submitted in the form of a comprehensive plan amendment, will be evaluated at both the local level and at a subregional level, as appropriate, and must satisfy the following criteria: 1.Forecasfs and Urban Land Demand. Is there demonstrated urban land need. The Council first reassesses land supply and demand based on current Council forecasts and a comparison of figures provided by the local governmental unit. The Council will analyze the local community's request in terms of the urban land supply/ demand in the pertinent regional data sector(s), cluster planning area, the sewer interceptor and treatment plant service area, and transportation corridor area to ensure a five-year overage. if the land supply is below or within three years of the five-year overage and regional facilities (transportation and sewer) are adequate, the Council will consider a service area expansion: in no case will land in a rural service area community be added to the MUSA for a net increase of serviced land unless there is a shortage of land suitable for development in the urban service area communities within the pertinent data sector(s). 2. Transportation and Sewer Service. Metropolitan transportation and sewer services must be in place or planned for implementation concurrent with the development proposed in the request. Analysis of transportation system impacts will include those communities or areas that are within the same regional transportation (highway or transit) corridor(s) or service area(s). Adequate capacity in the metropolitan sewer (treatment plant and interceptor) and highway systems must be available to serve any new development. Analysis of sewer service capacity will include those communities that are within the same service area of the wastewater treatment interceptor or treatment plant. 3.Staging. As communities seek to provide urban services to areas which are not currently urbanized, the communities must specify in five year urbanization areas, the timing and sequence of major local public facilities in the capital improvement program and also the official controls which will ensure that urbanization occurs only in designated urbanization areas and in accordance with the plan. 4.Rural Area Policy. Areas of the community not receiving urban services must be consistent with the Council's rural area policy for land uses and protection of prime agricultural land. 5.Local Comprehensive Sewer Plan. The focal government must have an up-to-date comprehensive sewer plan, including on-site sewer management. 6.Local Transportation Plan. The local government must have an up-to-date transportation plan. 7.Local Assessment Practices. The local government has assessment practices that limit creation of vested development rights. In addition, the request must also address how the community has and intends to address the following regional issues: 1.Housing Diversity. Local implementation of strategies and actions that allow for a variety of housing types and prices for current and future residents including building mixed-use or infill development and increasing density in residential development. 2.Environmenfal Resources. Use of environmental factors to guide urban development, concentrating development in areas environmentally suited for development. and 3. Shared Services. Local plans for service cooperation or consolidation and cost savings as well as the governmental unit's place and role the broader cluster context including relationship to school districts. 3 FORECASTS AND URBAN LAND DEMAND After the national recovery from the recession and high interest rates in the early 1980's, Lino Lakes has experienced an annual increase in the number of new homes since 1984. Low housing interest rates and strong growth in the cities to the south has strengthened the residential housing markets in Lino Lakes, resulting in unprecedented strong growth over the past five years. Table A illustrates the number of homes constructed in Lino Lakes since 1971. Through the 1970's, the City averaged 64.5 housing units a year. This average increased in the 1980's to 122 housing units annually. Since 1990, the number of new housing units increased to an average of 265 housing units annually, with a peak number of housing units at 375 occurring in 1993.

To avoid over -burdening City financial resources, utilities, services and personnel, the City Council determined that it was necessary to establish manageable growth parameters for the City of Lino Lakes. An average annual growth rate between the range of 200 and 300 units was identified as being appropriate for future planning efforts. DEMOGRAPHIC FORECASTS All past planning efforts have been based on demographic forecasts for the City of Lino Lakes. The City forecasts were periodically revised to reflect the changing growth patterns in the City. As shown in Table B, past forecasts have been close to the mark in projecting the 1990 population and household counts for the City. Both the City Comprehensive Sewer Plan and the 1993 Metropolitan Council demographic forecasts have made growth projections for Lino Lakes extending to 2010 and beyond. In review of these projections, the City assumed a growth rate of 210 units annually beyond the year 1990. The Metropolitan Council estimates a growth rate of 200 units annually between 1990 and 2010, with an increase to 240 units annually beyond 2010.

The forecasts represent a range of growth based on annual local growth of 200, 250 and 300 housing units annually.

New housing units from 1990 through 1994 factored by a 2% City-wide vacancy rate was used to generate household estimate. 3 Household size forecasts are reflective of the household size estimates of the Metropolitan Council. The 200 unit per year projection is generally consistent with demographic forecasts of the City Comprehensive Sewer Plan and the 1993 Metropolitan Council forecast. In review of the City's growth over the last five years, these projections may be very conservative. Continued growth in the northern Twin Cities metropolitan suburban communities has strengthened the residential markets in Lino Lakes. As previously noted, the construction rate since 1990 has more than doubled what was experienced in the previous decade. Since 1990, the City has averaged 265 new housing units per year. In 1992 and 1993, the City had issued 342 and 375 percents for new construction, respectively. The most recent growth characteristics suggest that Lino Lakes may sustain growth at a rate greater than 200 units per year. 6 The City's demographic projections showing average annual growth of 250 and 300 units represent a moderate and strong growth forecasts through the year 2000. In light of the limited land supply and other development limitations unique to Lino Lakes, the City would be supportive of a moderate growth rate of 250 units per year, provided that these forecasts can be periodically re-evaluated and adjusted to be reflective of actual development trends. RESIDENTIAL LAND DEMAND Based on the demographic forecasts, the City has estimated projected land demand to accommodate residential through year 2000. In generating these forecasts, the following development characteristics must be noted. Development Regulations Lino Lakes has seven residential zoning districts offering a broad variety of housing densities and types. While the City has experienced a variety of housing projects including single family, townhomes, manufactured housing, and elderly housing, the predominant housing type has been single family housing. Urban single family residential development typically falls into two zoning districts. R-1, Single Family Zoning District. This zoning district provides for an urban residential environment. Minimum lot size is 10,800 square feet and 80 foot lot widths. Based on these lot size requirements, this zoning district may provide a maximum density of 3.2 units per buildable acre. R -1X, Single Family Executive Residential District. This zoning district provides for urban residential neighborhoods that offer greater amenities. The minimum lot size is 12,825 square feet and 90 foot widths. This zoning district allows a maximum density of 3.0 units per buildable acre. The City zoning regulations and the 1991 Wetland Conservation Act have impacted the development densities occurring in Lino Lakes. The Lino Lakes development regulations require that all newly platted lots have a minimum required lot area that excludes street right-of-way, floodplain areas, wetlands, and water courses. This requirement is intended to protect environmentally sensitive areas, preserve necessary natural drainage systems, and assure the property owner adequate usable lot area to accommodate residential space needs. 7 The 1991 Wetland Conservation Act has significantly changed the rules of development. The primary purpose of the act is to regulate development in a manner that results in no net loss in wetland acreage. This requires urban development to design subdivisions that: 1) avoid wetlands; 2) minimizes impact if some intrusion on a wetland is necessary; and 3) mitigates wetlands that are impacted. Development Densities The aforementioned environmental regulations have significantly reduced the development densities that have occurred in Lino Lakes in the following ways: 1. The 1991 Wetland Conservation Act applies to all wetlands. As a result, it has removed development potential from land that may have previously been developed. This reduces the supply of buildable land within a subdivision. 2. Subdivisions that must integrate wetlands into the lot layout frequently lose density due to irregular shapes of the wetland resulting in oversized lots. 3. The City standard requiring the residential lot areas to be exclusive of water courses mandates larger lots in areas of wetlands, floodplains and environmentally sensitive areas. A survey of ten subdivisions (Table C) developed in accordance with the City regulations and the 1991 Wetland Conservation Act reveals that the residential densities are much lower than the density standards allowed in the base zoning districts. After the consideration of the wetlands as physical constraints, recent subdivisions produced a gross density of 1.4 units per acre and a net density of 2.1 units per buildable acre. 8 TABLE C RESIDENTIAL DEVELOPMENT LOT DENSITIES 1993 - 1994 Net Gross Densities Upland Density (Lots/Acre Zoning Plat Acres Acres Lots (Lots/Acre) of Upland) Designation Country Lake Estates 33 30.51 53 1.61 1.74 R-1 Oaks of Lino 9 4.19 9 1.00 2.15 R-1 Fox Trace 25 21.72 55 2.20 2.53 R-1 Pine Ridge II 10 9.01 18 1.80 2.00 R -1X Pine Ridge III 10 9.31 19 1.90 2.04 R -1X QD Trappers Crossing 72 57.14 115 1.60 2.01 R -1X Quail Ridge 38 22.20 40 1.05 1.80 R -1X Pheasant Hills I -VI 120 60.00 125 1.04 2.08 R -1X Behm's Century Farm 93 52.36 153 1.65 2.92 R-1 Clearwater Creek Phase I and II 120 80.60 154 1.28 1.91 R-1 TOTAL 530 347.04 741 1.40 2.14 FUTURE MUSA DEMAND To accommodate future projected growth in Lino Lakes, it is necessary to have a sufficient supply of buildable land and infrastructure capacity. Based on the growth parameters established for the City, land demand has been forecasted in Table D. The land demand projection illustrates the anticipated number of housing units divided by the City average urban density to generate estimated land demand by buildable acres. Consistent with Metropolitan Council guidelines, the demand is then adjusted to provide a five year overage in land supply. Based on anticipated growth, Lino Lakes will have a 2000 MUSA land demand with overage ranging from 750 to 1,125 acres.

This figure was based on the MUSA boundaries established with the 1990 Comprehensive Plan amendment, as shown on Map 1. Within the total MUSA, Metropolitan Council staff estimated that 2,134 acres of land was buildable and available for new development. Metropolitan Council estimates, shown in Table E, were generated through the use of a region -wide GIS system that quantified the amount of various land uses, National Wetland Inventory features, and undeveloped land within the City. 10 • I g el se eae• .r I • 1 CtxrEaviLLE me I3a Uo LAIL, mo PCS. 334 MAP 1 Urban Service Area Boundary 11 N TABLE E 1993 METROPOLITAN COUNCIL ESTIMATE OF LINO LAKES MUSA IN ACRES Residential Iso- Public and Multi- Single lated Recreation High Lakes & Family Family Farm Commercial Industrial Public Rec. ways Streams Vacant Total 1984 0 446 5 6 32 66 62 48 157 864* 1,686 1990 0 843 31 33 101 113 203 98 159 2,134** 3,715 Change 1984- 1990 0 397 26 27 69 47 141 50 2 1,270 * Does not include 376 acres of wetlands in vacant land (#8). ** Does not include 684 acres of wetlands in vacant land (#8). SOURCE: Metropolitan Council 1993 Lino Lakes staff expressed concern over the estimated acreage of buildable MUSA presented by the Metropolitan Council. Existing development patterns in the City suggested that the supply of land available for development was significantly less than the Metropolitan Council estimate. To attain an accurate inventory of land available for development, the City mapped the existing MUSA on a section by section basis to allow for a detailed visual tabulation of the gross MUSA, as well as a net buildable MUSA available for residential development. The gross MUSA was tabulated using a planimeter over the 1990 MUSA boundary map. The detailed tabulation of net buildable land used the following methodology: Step #1: The City produced 200 scale aerial photographic base maps that were overlaid by same scale mylar section map and acetate National Wetland Inventory (NWI) maps. These maps provide a section by section base data of land use, and NWI wetlands at a scaled dimension. Step #2: Once a base map for each section of the City was created, the City delineated the MUSA boundaries, non- residential zoning districts, and the County park land. Step #3: At Step 3, the buildable vacant land available for residential development could be determined as of year end 1993. Land considered for development was upland area of residentially zoned parcels with a contiguous area of 5 acres or more. Lands included in previous approved final plats was not considered available: The buildable land was shaded in yellow to allow for measurement. The limiting boundaries of the wetlands were the more restrictive combination of the NWI and the 1977 wetland delineation on the section map. All land areas were calculated on a section by section basis using a planimeter. The results of the City efforts are illustrated in Table F. METHODOLOGY FOR CALCULATING AVAILABLE RESIDENTIAL BUILDABLE MUSA - Available Acres Shaded. - MUSA, County Park, and Zoning Boundaries. - 200 Scale Section Base Map. - Aerial Photography Map. Table F indicates that 895 acres of buildable MUSA is available for residential development. This supply is further reduced by development that occurred in 1994, and the difference between actual wetlands delineated at time of final plat and the wetlands defined by the NWI map. In 1994, Lino Lakes issued 213 building permits for new homes. One hundred thirty-three of these building permits consumed lots within plats approved prior to 1994, reducing the available lot supply in the pre 1994 plats. Seventy-four single family lots in eight plats scattered throughout the City. No single pre 1994 plat has more than 13 vacant lots available. Due to limited and dispersed supply of vacant lots existing in pre 1994 plats, land included in these plats was not considered part of the available 895 acres of existing buildable MUSA shown in Table F. Table E indicates that 895 acres of buildable MUSA are available for residential development. This supply is further reduced by development occurring in 1994, and the difference between actual wetland delineated at time of final plat and the wetlands defined by the NWI map. In 1994, Lino Lakes issued 213 building permits for new homes. One hundred thirty-three of these building permits consumed lots within plats approved prior to 1994, reducing the available lot supply in pre 1994 plats to 74 single family lots in eight plats scattered throughout the City. No single pre 1994 plat has more than 13 vacant lots available. Due to limited and dispersed supply of vacant lots existing in pre 1994 plats, land included in these plats was not considered available as existing buildable MUSA. In addition to the development occurring in plats approved prior to 1994, Lino Lakes also issued 80 building permits for housing units for plats approved and developed in 1994. Table G, below, illustrates the development and land absorption of lots created by plats approved in 1994. The residential development occurring in 1994 plats consumed 31 acres which was subsequently subtracted from the City's estimated supply of available MUSA year end 1993. 14 12/93 Areas TABLE F LINO LAKES BUILDABLE LAND INVENTORY 1993 CITY OF LINO LAKES N 0, N 0, N (n rn 0, (n V) N N N 0) V) V) V) (n V) V) (1) (1) (1) V) V) N (n N (A V) V) (1) 0) (n (p fD (p) 2 2 (5 (1) (D fD fD 0 0 o 0 o 0 o 0 0 0 0 o n 0 0 0 o 0 o 0 C) 0 C) 0 o o 0 o 0 6 o 6- 5- 6- a o o 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0. 0 0 0 0 0 0- 0 0 0 0 0 7 7 7 7 7 7 D 7 _ __ _ __ __ _ �_ __ _ __ __ _ = 7 7 _ _ = 7 = _ _ _ _ _ _ _ -' N W A Cr' Cr' J 0) (O O --� N W A Ut a) v W (o O '2N8 a Cn 0N) V N (No O (-.1 N o 2 CW)) O) 9 d MUSA Acres Comercial Zoned MUSA Industrial Zoned MUSA Public Zoned MUSA Residential Zoned MUSA Total Residential Developed MUSA NWI Acres within MUSA Available Acres within MUSA (Upland Residential Zoned MUSA on Lots Larger Than 5 Acres) Non-MUSA Acres State ROW Acres Lake Acres County Park Non-MUSA NWI Acres Non-MUSA Available Acres (Upland Residential Zoned Non-MUSA on Lots Larger Than 5 Acres) Total NWI Acres Total Available Acres Total Acres 0 0 0 35 210 0 0 285 10 0 0 0 0 0 0 0 295 270 430 90 80 0 0 350 245 0 265 450 255 180 315 185 100 0 0 0 4050 0 0 0 13 3 0 0 88 10 0 0 0 0 0 0 0 100 0 25 11 0 0 0 145 0 0 0 0 0 30 50 0 0 0 0 0 475 0 0 0 7 0 0 0 7 0 0 0 0 0 0 0 0 120 65 16 0 0 0 0 205 0 0 0 0 0 0 0 0 0 0 0 0 420 0 0 0 0 12 0 0 0 0 0 0 0 0 0 0 0 0 110 20 0 10 0 0 0 0 0' 48 25 30 0 0 10 0 0 0 0 265 0 0 0 15 195 0 0 190 0 0 0 0 0 0 0 0 75 95 369 79 70 0 0 0 245 0 217 425 225 150 265 175 100 0 0 0 2890 0 0 0 20 15 0 0 70 0 0 0 0 0 0 0 0 20 45 255 25 70 0 0 0 0 0 45 140 175 50 160 135 0 0 0 0 1225 0 0 0 5 110 0 0 10 0 0 0 0 0 0 0 0 25 10 100 15 15 0 0 35 60 0 75 125 80 40 45 50 20 0 0 0 820 0 0 0 0 70 0 0 120 0 0 0 0 0 0 0 0 20 40 5 40 0 0 0 0 175 0 70 125 25 65 50 15 75 0 0 0 895 665 635 635 585 420 640 630 345 610 630 635 665 665 320 320 630 340 360 225 555 560 640 0 140 405 530 380 190 390 320 335 455 540 645 635 640 17315 40 50 0 0 0 0 0 10 35 40 5 40 40 0 0 0 55 35 40 0 0 0 0 50 45 0 0 0 0 10 5 0 0 0 45 15 560 0 20 235 0 0 0 0 0 50 45 140 0 0 135 120 385 145 0 50 265 185 405 0 0 0 0 15 135 150 210 100 0 0 0 215 105 3110 0 85 0 0 0 0 0 5 130 345 180 0 0 0 200 245 130 0 0 290 385 200 0 0 0 0 0 0 100 100 45 0 0 0 0 0 2440 115 420 475 125 155 140 130 20 295 385 400 50 70 150 220 500 235 25 50 410 470 515 0 30 105 95 125 185 235 265 190 130 240 270 290 335 7850 185 150 65 250 130 460 260 25 95 45 155 140 0 150 0 0 0 0 20 0 0 0 0 0 160 365 160 10 30 0 30 150 255 295 120 65 3770 115 420 475 130 265 140 130 30 295 385 400 50 70 150 220 500 260 35 150 425 485 515 0 1 65 165 95 200 310 315 305 235 180 260 270 290 - 335 8670 185 150 65 250 200 460 260 145 95 45 155 140 0 150 0 0 20 40 25 40 0 0 0 0 335 365 230 135 55 65 80 165 330 295 120 65 4665 665 635 635 620 630 640 630 630 620 630 635 665 665 320 320 630 635 630 655 645 640 640 0 490 650 530 645 640 645 500 650 640 640 645 635 640 21365 i7fi.`/.a L Zsee 12/20/94 Plat TABLE G DEVELOPMENT IN PLATS APPROVED IN 1994 Net Additional Total Vacant Percent Gross Available Available Developed Lots Lots Vacant Acres Acres Acres Used Acres Pheasant Hills III, IV, V, and VI 91 64 70 101 48 14.24 29.97 Country Lake Estates 53 45 85 35 27 4.08 5.28 Fox Trace 55 50 91 25 25 2.27 2.27 Quail Ridge 40 2 5 40 20 19.00 38.00 Pine Ridge II 18 17 94 8 8 .44 .44 Oaks of Lino 9 8 89 10 7 .78 1.11 Wenzel Farms 5th Addition 50 50 100 20 0 .00 .00 316 236 75 239 135 40.80 77.10 The second factor influencing the available buildable MUSA is the difference between actual wetland areas delineated in accordance with the 1991 Wetland Conservation Act and the wetland boundaries depicted on the National Wetland Inventory (NWI) map. In tabulating available MUSA, the Metropolitan Council credited wetland areas identified in the NWI maps. The City, using nine subdivision applications having wetland delineations completed, has conducted a comparison between actual wetlands to the NWI wetlands. Table H illustrates that the subdivisions being developed under the Wetland Conservation Act are displayed an average of 50 percent more wetland area than was defined by NWI maps for these plats.

The trend suggests that 1.5 percent ratio show in Table H above represents a conservative adjustment to the NWI wetlands when determining the actual supply of vacant buildable residential MUSA. 17 Table I shows the adjustments to the available residential acres within the MUSA as tabulated 1 January 1994 by subtracting net residential land absorption occurring during 1994 and adjusting the NWI wetlands to be reflective of actual wetland experiences. Year end 1994, the City estimates 444 acres of buildable residential MUSA remaining. TABLE I YEAR END 1994 AVAILABLE RESIDENTIAL MUSA Available acres within MUSA as of 1/1/94 895 Available acres used in 1994 on a per lot basis (from "Net Available Acres Used") - 41 Available acres within MUSA as of 1/1/95 854 Additional wetland from "Actual Wetland Acres to NWI Based Wetland Acres Ratio" (1.5 * 820 acres NWI - 820 acres) - 410 Adjusted available acres within MUSA as of 1/1/95 444 In addition to the limited supply of buildable land, the location of this land further complicates urban growth. The City's supply of buildable MUSA is scattered throughout the community, however, the largest contiguous parcels -are located east of I-35 and along Main Street. These parcels are located away from existing infrastructure. The extension of utilities is difficult without a development having the critical mass for financing both the utility extension and the internal plat improvements. This is required due to the Charter restriction that prevents the assessing of utilities without the permission of adjoining property owners. This situation stalls growth and does not promote contiguous growth patterns or the orderly extension of utilities. Anoka County assessment policy of valuing land having a MUSA designation at $2,000 per acre higher than rural service property suggests a financial vested interest in the MUSA designation. Land trades that would remove the MUSA from one acre of the City for use in another is seen as taking value away from the property. The City is reluctant to become involved with taxing issues and compensation for lost value. A final discrepancy between Metropolitan Council's estimate of available MUSA and the City is that Met Council included land areas in oversized unsewered lots as land available for development. The City's calculation for available MUSA excludes any unsewered lots of single ownership having land areas less than 5 acres. The basis for this proposal is as follows: 18 1. The City Charter allows City residents to refuse special assessments for infrastructure improvements until such time as they made connection to the utility. Additionally, the Charter restricts the use of general funds in the use of infrastructure projects. The result of the Charter is that it prohibits the City from installing utilities in areas of unsewered lots unless they are petitioned for by the neighborhood and residents accept the special assessments. 2. Multiple property ownership, in conjunction with the City Charter complicates land assembly, prohibiting the creation of a single parcel large enough to create the critical masses to accommodate a privately financed project. Table J compares the Lino Lakes projected residential land demand through the year 2000 with its existing supply to identify the necessary MUSA expansion acreage. TABLE J MUSA EXPANSION ACREAGE Growth Year Parameter 2000 Demand Existing Supply Proposed MUSA Unit Per Year With Overage of Buildable MUSA Expansion Acreage 200 714 - 444 270 250 892 - 444 448 300 1,071 - 444 627 LAND BANK The current discrepancies between the Metropolitan Council's and Lino Lakes' estimate of buildable vacant MUSA is attributed in part to the way MUSA has been applied to land areas in the past. The blanket application of MUSA to anticipated growth areas has not provided for an accurate accounting of buildable land within the MUSA. As a result, some of the development potential assumed within a MUSA designation is far less than actually exists. This is particularly constraining in Lino Lakes due to the following local conditions: Buildable Land In January 1995, the City estimated that of the 21,365 acres within the corporate boundaries of Lino Lakes, only 45 percent or 9,695 acres are considered developable due to regional park, interstate highways, and environmental constraints inherent in the City. This has reduced the supply of buildable land in the Lino Lakes MUSA and reduced the development densities City-wide. Development proposals 19 considered under the wetland rules reveal the wetland impacts within the City are greater than originally believed, further reducing the supply of buildable land below the aforementioned 1995 estimate. 1991 Wetland Conservation Act The 1991 Wetlands Conservation Act significantly changed the rules for development. This act's primary purpose is to regulate development in a manner that results in no net loss in wetland acreage. This requires urban development to design subdivisions that: 1) avoid wetlands; 2) minimize impact if some intrusion on the wetland is necessary; and 3) mitigate wetlands that are impacted. Due to the extent of wetlands in Lino Lakes, the Conservation Act has significantly impacted the supply of buildable land, development densities, and development patterns in the City. The City survey of nine subdivision designs in accordance with the Wetland Conservation Act reveals that actual delineated wetlands exceeded NWI wetlands by approximately 50 percent. Past Development Patterns Prior to the 1990 Comprehensive Plan amendment and the 1992 Zoning Ordinance amendment that repealed the SR, Suburban Residential and SRX, Suburban Residential Executive Zoning Districts, the City allowed unsewered subdivisions with a minimum lot size of 2.5 acres. The 1990 and 1992 amendments served to implement a rural service policy of one unit per 10 acres consistent with Metropolitan Council guidelines. Review of Lino Lakes reveals a scattered pattern of unsewered subdivision impact on community growth in the following ways: 1. The subdivision established a suburban density that raises concern with regard to compatibility with urban densities. 2. The subdivisions are often resistant to the extension of utilities due to the cost of assessment to the larger lots. This resistance complicates the future planning and construction of local infrastructure. 3. The sensitive environmental features (i.e., wetlands/soils, high water table, lakes) inherent in Lino Lakes presents concern with regard to the proper functioning of on-site septic systems and the potential for their failure. The concentration of unsewered small lots present utility and environmental concerns if large scale failure would occur. 20 City Charter Lino Lakes is a charter city. The City Charter allows residents to refuse assessments for infrastructure improvements until such time as they made connection to the utility. This unique charter provision limits the City in its future utility planning. Local Assessment Practices The City has investigated possible land trades that would exchange MUSA areas. In review of this alternative, it was discovered Anoka County's policy to assess a higher taxable value on undeveloped land having a MUSA designation than undeveloped land outside the established MUSA. As a result of the property owners increased financial investment due to the land MUSA designation, the City believes that the County assessment policy creates a vested development right in the property. Exchange of MUSA area would require compensation for the loss of value in the property. LAND BANK PROCEDURE In an effort to more efficiently utilize the MUSA allocated to Lino Lakes and to provide some degree of flexibility and accuracy in community planning, the City is requesting the Metropolitan Council allow the City to establish a MUSA land banking system. The City would request that its 2000 MUSA be expanded by 448 acres. Under the land bank concept, this MUSA expansion acreage would be held in reserve and dispersed as development proposals are evaluated through a formal review process. For future proposed developments, the system to be implemented will involve an additional requirement in the application and formal review process. As part of the. City's approval of building plans or platting and development process (which requires improvement commitments on the part of the developer), a minor Comprehensive Plan amendment involving Metropolitan Council review will be required. The Plan amendment which is intended for advisory purposes only to the Metropolitan Council and will involve an addition to the 2000 Urban Service Area, under current limitations not to exceed 448 acres of the land reserve designated for development by 2000. The Comprehensive Plan amendment process will involve a review by the Metropolitan Council. To insure the Metropolitan Council that the urban residential growth follows an orderly and logical growth pattern, the City proposes to designate an urban expansion area which will confine the use of the MUSA reserve acres. Consistent with the following policy parameters, the urban expansion area will include the existing MUSA boundaries and 672 additional acres which will allow 21 • for some flexibility in the use of the MUSA reserve. The following parameters will also guide the distribution of the land reserve MUSA in a manner that will promote staged, orderly growth while maximizing the use of the MUSA allocation and infrastructure investment. 1. The property is contiguous to the existing MUSA and provides a logical extension of utilities in an orderly growth pattern. 2. Utility improvements respond to environmental, health, safety, and general welfare concerns. 3. The land is not green acred or agricultural preserve. 4. The potential sewer discharge of the project is within limitations assigned to the City of Lino Lakes by regional agencies. 5. The developer/benefitting property owners assume the significant majority of improvement/service costs, and agree to pay assessments associated with extending service to serve their property. 6. The proposed MUSA expansion or trade is consistent with the City's infill policy which encourages urban development to locate wherever possible in areas where public investments have already been provided. 7. In considering land trades, the City should not exchange developable commercial or industrial zoned land for a proposed residential development unless fiscal impact concerns are fully addressed. 8. The developer acknowledges and holds all governmental units harmless should limitations on sewer hookups be imposed. 9. The land does not qualify as a premature development or subdivision based on the following: a. Lack of adequate storm water drainage capacity b. Lack of adequate or safe water supply. c. Lack of adequate roads or highways to serve the subdivision or development. d. Lack of adequate or safe sewage disposal. e. Inconsistent with the Comprehensive Plan. f. Lack of adequate public support facilities (i.e., schools, parks and recreation, fire and police, etc.). g Inconsistent with environmental protection policies. 22 'pit The property owner pursuing the proposed development must demonstrate compliance with the aforementioned guidelines to secure MUSA allocation. The assignment of MUSA would occur with the approval of the final plat and would represent the net buildable area of the plat. The benefits of the urban expansion area and MUSA land bank system include: 1. The MUSA from the land reserve would be assigned on the net buildable acres of the subdivision or development. This would be quantified by the City during the review process. This will provide an accurate accounting of consumed MUSA and utility capacity. 2. The assignment of MUSA with the final plat assures timely use of the MUSA designation. Final plat approval requires financial guarantees and a development agreement to insure development performance. 3. The land bank system provides a degree of flexibility with regard to community planning. Without the geographic designating of the MUSA, the City avoids creating a vested property right via Anoka County tax assessment policy. This allows the City to address areas experiencing development pressures. 4. The land bank system will allow for the logical expansion of urban growth that will bring urban utilities in closer proximity to unsewered subdivisions. This sewer availability is necessary to allow the City to respond in the event of septic system failure. 5. Due to the Charter limitation, public utility extension will be development driven and financed in the future. The land bank system allows the City some flexibility to accommodate development that helps facilitate the City's long range utility infrastructure planning. 23 DRAFT 1/5/95 CHAPTER 1102 SHORELAND MANAGEMENT OVERLAY ORDINANCE 1102.01 Statutory Authorization and Policy 1102.02 General Provisions 1102.03 Definitions 1102.04 Administration 1102.05 Shoreland Overlay District 1102.06 Shoreland Overlay District Uses 1102.07 Zoning and Water Supply/Sanitary Provisions 1102.08 Nonconformities 1102.09 Shoreland Alterations 1102.10 Special Provisions for Commercial, Industrial, Public./Semipublic, Agricultural, Forestry and Extractive Uses and Mining of Metallic Minerals and Peat 1102.11 Water Supply and Sewage Treatment 1102.12 Subdivision/Platting Provisions 1102.13 Planned Development Overlays (PDOS) 1102.01 Statutory Authorization and Policy Subdivision 1.

Lots of record in the Office of the County Recorder prior to the date of enactment of this ordinance which do not meet the requirements of 1102.07, Subd. 1 may be allowed as building sites without variances from lot size requirements provided: 1. such use is permitted in the underlying zoning district, 2. the lot is and has been in separate ownership from abutting lands at all times since it became substandard, 3. the lot was created compliant with official controls in effect at the time, 4. all other dimensional requirements are complied with insofar as practical, and 5. sewage treatment and setback requirements of this ordinance are met. B. A variance from setback requirements must be obtained before any use or building permit is issued for a lot. In evaluating the variance, the City Council shall consider sewage treatment and water supply capabilities or constraints of the lot and shall deny the variance if adequate facilities cannot be provided. Page 19 DRAFT 1/5/95 C. If, in a group of two or more contiguous lots under the same ownership, any individual lot does not meet the requirements of Section 1102.07, Subd. 1 of this ordinance the lot must not be considered as a separate parcel of land for the purposes of sale or development. The lot must be combined with the one or more contiguous lots so they equal one or more parcels of land, each meeting the requirements of Section 1102.07 of this ordinance as much as possible. Subd. 2. Additions/expansions to nonconforming structures. A. All additions or expansions to the outside dimensions of an existing nonconforming structure must meet the setback, height, and other requirements of this ordinance. Any deviation from these requirements must be authorized by a variance pursuant to 1102.04, Subd. 3. B. Deck additions may be allowed without a variance to a structure not meeting the required setback from the ordinary high water level if all of the following criteria and standards are met: 1. the structure existed on the date the structure setbacks were established; 2. a thorough evaluation of the property and structure reveals no reasonable location for a deck meeting or exceeding the existing ordinary high water level setback of the structure; 3. the deck encroachment toward the ordinary high water level does not exceed 15 percent of the existing setback of the structure from the ordinary high water level or does not encroach closer than 30 feet, whichever is more restrictive; and 4. the deck is constructed primarily of wood, and is not roofed or screened. Subd. 3. Nonconforming sewage treatment systems. A. A sewage treatment system not meeting the requirements of Section 1102.11 of this ordinance must be upgraded, at a minimum, at any time a permit or variance of any type is required for any improvement on, or use of, the property. For the purposes of this provision, a sewage treatment system shall not be considered nonconforming if the only deficiency is the sewage treatment system's improper setback from the ordinary high water level. B. The governing body of the City of Lino Lakes has by formal resolution notified the commissioner of its program to identify nonconforming sewage treatment systems. The City of Lino Lakes will require upgrading or replacement of any nonconforming system identified by this program within a reasonable period of time which will not exceed 2 years. Sewage systems installed according to all applicable local shoreland Page 20 DRAFT 1/5/95 management standards adopted under Minnesota Statues, section 105.458, in effect at the time of installation may be considered as conforming unless they are determined to be failing, except that systems using cesspools, leaching pits, seepage pits, or other deep disposal method, or systems with less soils treatment area separation above groundwater than required by the Minnesota Pollution Control Agency's Chapter 7080 for design of on-site sewage treatment systems shall be considered nonconforming. 1102.09 Shoreland Alterations. Alterations of vegetation and topography in the Shoreland Overlay District will be regulated to prevent erosion into public waters, fix nutrients, preserve shoreland aesthetics, preserve historic values, prevent bank slumping, and protect fish and wildlife habitat. Subdivision 1. Vegetation Alterations. A. Vegetation alteration necessary for the construction of structures, sewage treatment systems, uses permitted in the underlying zoning district and the construction of roads and parking areas regulated by 1102.09, Subd. 3 of this ordinance are exempt from the vegetation alteration standards that follow. B. Removal or alteration of natural vegetation, except for agricultural and forest management uses as regulated in Section 1102.10, shall be restricted to prevent erosion into protected waters, to consume nutrients in the soil, and to preserve shoreland aesthetic. Removal of natural vegetation in the Shoreland Overlay District is allowed subject to the following standards: 1. Clear cutting of natural vegetation is prohibited. 2. Limited clearing of trees and shrubs and cutting, pruning, and trimming of trees is allowed to provide a view to the water from the principal dwelling site and to accommodate the placement of stairways and landings, picnic areas, access paths, beach and watercraft access areas, and permitted water - oriented accessory structures or facilities, provided that: a. the screening of structures, vehicles, or other facilities as viewed from the water, assuming summer, leaf -on conditions, is not substantially reduced; b. along rivers, existing shading of water surfaces is preserved; c. the above provision is not applicable to the removal of trees, limbs, or branches that are dead, diseased, or pose safety hazards. 3. Natural vegetation shall be restored insofar as feasible after any construction project is completed to retard surface runoff and soil erosion. Page 21 DRAFT 1/5/95 4. The provisions of this section shall not apply to permitted uses which normally require the removal of natural vegetation. Subd. 2. Topographic Alterations/Grading and Filling. A. Grading, filling and excavations necessary for the construction of structures, sewage treatment systems, driveways and other uses permitted in the underlying zoning district under validly issued construction permits for these facilities do not require the issuance of a separate grading and filling permit. However, the grading and filling standards in this Section must be incorporated into the issuance of permits for construction of structures, sewage treatment systems and driveways. B. Public roads and parking areas are regulated by Section 1102.09, Subd. 3 of this ordinance. C. Notwithstanding Items A and B above, a grading and filling permit» :* r dar a +i t Section 4` Subd.:: ::bf::the:C�:.:.:.> on 3rdinanc < will be required for: 1. the movement of more than ten (10) cubic yards of material on steep slopes or within the shore impact zone; and 2. the movement of more than 50 cubic yards of material per acre. D. The following considerations and conditions must be adhered to during the issuance of construction permits, grading and filling permits, conditional use permits, variances and subdivision approvals: 1. Grading or filling in any wetland must be evaluated to determine the extent of impact to the functions and values of the wetland area in accordance with Section 1104 of the City Code. This evaluation must also include a determination of whether the wetland alteration being proposed requires permits, reviews, or approvals by other local, state, or federal agencies such as a watershed district, a local governmental unit, the Minnesota Department of Natural Resources, or the United States Army Corps of Engineers. The applicant will be so advised. 2. Alterations must be designed and conducted in a manner that ensures only the smallest amount of bare ground is exposed for the shortest time possible. Mulches or similar materials must be used, where necessary, for temporary bare soil coverage, and a permanent vegetation cover must be established as soon as possible; 3. Methods to minimize soil erosion and to trap sediments before they reach any surface water feature must be used. Altered areas must be stabilized to acceptable erosion control standards consistent with the field office technical Page 22 DRAFT 1/5/95 guides of the Anoka County Soil and Water Conservation District and the United States Soil Conservation Service; 4. Fill or excavated material must not be placed in a manner that creates an unstable slope. Plans to place fill or excavated material on steep slopes must be reviewed by qualified professionals for continued slope stability and must not create finished sloped of 30 percent or greater; 5. Any alterations below the ordinary high water level of the waterbodies described in 1002.05, Subd. 1B must first be authorized by the Commissioner under Minnesota Statutes, Section 105.42; 6. Alterations of topography must only be allowed if they are necessary to allow a defined permitted accessory or conditional use within the underlying zoning district and do not adversely affect adjacent or nearby properties; and 7. Placement of natural rock riprap, including associated grading of the shoreline and placement of a filter blanket, is permitted if the finished slope does not exceed three feet horizontal to one foot vertical, the landward extent of the riprap is within ten feet of the ordinary high water level, and the height of the riprap above the ordinary high water level does not exceed three feet. E. Connections to public waters. Excavations where the intended purpose is connection to a public water, such as boat slips, canals, lagoons, and harbors, must be controlled by local shoreland controls. Permission for excavations may be given only after the Commissioner has approved the proposed connection to public waters. Subd. 3. Placement And Design of Roads, Driveways, and Parking Areas. A. Public and private roads and parking areas must be designed to take advantage of natural vegetation and topography to achieve maximum screening from view from public waters. Documentation must be provided by a qualified individual that all roads and parking areas are designed and constructed to minimize and control erosion to public waters consistent with the Lino Lakes Local Water Management Plan. B. Roads, driveways, and parking areas must meet structure setbacks and must not be placed within shore impact zones when other reasonable and feasible placement alternatives exist. If no alternatives exist, they may be placed within these areas, and must be designed to minimize adverse impacts. C. Public and private watercraft access ramps, approach roads, and access -related parking areas may be placed within shore impact zones provided the vegetative screening and erosion control conditions of this subpart are met. For private facilities, Page 23 DRAFT 1/5/95 the grading and filling provisions of 1102.09, Subd 2 of this ordinance must be met. Subd. 4. Stormwater Management. A. Impervious surface coverage of lots must not exceed the impervious surface percentage of lot area outlined in Section 1102.07 C4 of this ordinance. B. When possible, existing natural drainageways, wetlands and vegetated soil surfaces must be used to convey, store, filter, and retain stormwater runoff before discharge to public waters. C. Development must be planned and conducted in a manner that will minimize the extent of disturbed areas, runoff velocities, erosion potential, and reduce and delay runoff volumes. Disturbed areas must be stabilized and protected as soon as possible and facilities or methods used to retain sediment on the site. D. When development density, topographic features, and soil and vegetation conditions are not sufficient to adequately handle stormwater runoff using natural features and vegetation, various types of constructed facilities such as diversions, settling basins, skimming devices, dikes, waterways, and ponds may be used. Preference must be given to designs using surface drainage, vegetation, and infiltration rather than buried pipes and man-made materials and facilities. Residential, commercial and industrial subdivisions and site plans shall provide for the collection and treatment of storm water in compliance with the City Storm Water Management Plan if determined that the site improvements will result in increased runoff directly entering a public water. All grading and drainage plans shall require review and approval by the City Engineer and the Rice Creek Watershed District. E. When constructed facilities are used for stormwater management, documentation must be provided by a qualified individual that they are designed and installed consistent with the Lino Lakes Local Water Management Plan. F. Newly constructed stormwater outfalls to public waters must provide for filtering or settling of suspended solids and skimming of surface debris before discharge. 1102.10 Special Provisions for Commercial, Industrial, Public/Semipublic, Agricultural, Forestry and Extractive Uses and Mining of Metallic Minerals and Peat.
