4.0 Identified Issues, Goals and Policies 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). Issues, goals and policies have been identified under the following categories: 4.1 Water Rate & Quantity 4.2 Water Quality 4.3 Wetland Management 4.4 Floodplain Management 4.5 Public Ditch System 4.6 Groundwater Management 4.7 Natural Resources 4.8 Erosion and Sediment Control 4.9 Regulations, Permitting and Reporting 4.10 Monitoring, Maintenance and Inspection 4.11 Public Participation, Information and Education 4.12 Financing 4.1. Water Rate & 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 inches 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 CFS will be generated from the 534 acre area within Lino Lakes that is currently served by ACD 55. The ACD 55 infrastructure currently City of Lino Lakes SWMP 1 December 20151 64
