DRAFT 2040 Comprehensive Plan Update – Local Water Management Plan 25 December 27, 2017 - Project CLL17010 2.9 Proposed Conditions Lino Lakes is expected to add a significant number of households by 2040. As part of the metropolitan region, the City is required to accommodate a portion of the region’s forecasted growth. As Lino Lakes grows, it is anticipated that development patterns will change in many areas of the City. In Chapter 3 of the Lino Lakes 2040 Comprehensive Plan, a key component of developing the future land use plan was analysis of a wide variety of natural resource information. This included the location of high priority wetlands and other natural resource areas, drainage patterns, and soil suitability information, to identify environmentally sensitive areas and areas most suitable for development. This natural resource information was used to guide decisions regarding future land uses and intensities in Lino Lakes. Based on the development suitability information, a full build-out future land use plan was developed (Appendix A, Figure 15). The Metropolitan Council requires that communities plan for growth up to 2040 in their current comprehensive plans. Areas that will not be developed until after 2040 are designated on the 2040 future land use map as Urban Reserve. Although the 2040 Future Land Use Plan (Appendix A, Figure 16) will serve as the City’s official Future Land Use Plan to regulate future development, the full build-out plan is also provided for reference to guide future land use decisions regarding 2040 Urban Reserve areas. The City’s goals and strategies relating to natural resources were also considered throughout the development of the plan. Providing for higher density uses on some sites with scenic natural amenities such as wetland areas or along the shores of Peltier Lake also promotes accessibility to key community features and natural amenities, which is another community goal, for residents of higher density housing. Identifying higher density options in these areas also addresses the community’s goal and related strategies to sustain Lino Lakes’ natural resources by promoting more flexible development in these areas. Accommodating higher density in these areas provides for more site plan flexibility, as development can be concentrated on areas of the site more suitable for development while environmental features are preserved as open space. As Lino Lakes develops, protection of its valuable natural resources will continue to play an important role in guiding growth and shaping future development. Growth and economic development objectives should be balanced with managing natural resource systems. Natural resource protection strategies are also an essential component of a growth management plan to ensure that the community’s resources are preserved. The City has several tools to protect natural areas while also managing future growth. These tools are further outlined in Chapter 2 of the Lino Lakes 2040 Comprehensive Plan and additional information on future land uses is available in Chapter 3 of the City of Lino Lakes 2040 Comprehensive Plan. 3. ASSESSMENT OF WATER RESOURCE-RELATED PROBLEMS AND ISSUES Issues, goals and policies were developed for this Plan through a process of compiling issues and goals identified in plans and studies previously completed by the City and other local agencies. Primary sources of information were the previous Surface Water Management Plan, the City’s Comprehensive Plan, Resource Management Plans, and Watershed Management Plans of the Rice Creek Watershed District and Vadnais Lake Area Watershed Management Organization. The compiled goals and policies were refined by city staff and consultants for review by the City of Lino Lakes Environmental Board (whose purpose is to advise the city council in the use and management of its natural resources). The primary issues facing the City of Lino Lakes are: 1. Challenges in meeting stormwater volume reduction goals due to poor soils in the southeast corner of the City 2. Flood control issues in the Chain of Lakes 3. Antiquated public ditch systems without capacity for future development and stormwater runoff 3.1 Issues A detailed list of the City-wide and RMU-specific water resources issues facing the City of Lino Lakes is provided in Appendix E, and summarized below. Water Rate and Quantity Issues Within the City of Lino Lakes, streams, lakes, and wetlands have been subjected to increased surface water runoff rates and volumes. Increased discharge rates and volumes have caused serious down-cutting and stream bank erosion in some areas. Increased runoff rates and volumes also contribute to flooding concerns and water quality concerns. These issues are likely to intensify in the future. The Metropolitan Council prepared and adopted a regional growth strategy that anticipates further urbanization of the City. In addition, transportation improvements in or near the City will facilitate and precipitate urbanization. The City of Lino Lakes is planning for development of 1,400 acres east of Peltier Lake, North of Main Street. Furthermore, the City of Hugo is planning for development of a 215-acre area; both areas are currently being drained by Anoka County Ditch 55 (ACD 55). Currently, precipitation events larger than 0.25-inch results in surface water ponding and surface water runoff within the ACD 55 drainage area (Houston Engineering, 2013b). Without an alternative outlet or increased capacity, the development may be limited within the ACD 55 drainage area. This may exacerbate current flooding up stream in the ACD 55 system since ACD 55 restricts downstream flows and can only accommodate a small amount of flow. Sediment loads, and with it pollutants and contaminants, would also increase. Flow from the 215-acre area within the City of Hugo may be up to 62 cfs during the 100-year 24-hour storm. Additionally, 54 cubic feet per second (cfs) will be generated from the 534-acre area within Lino Lakes that is currently served by ACD 55. The ACD 55 infrastructure currently reaches capacity at
