Feasibility Report Northeast Lino Lakes Drainage Improvement Project WSB Project No. 2029-790 Page 1 1. EXECUTIVE SUMMARY The surface water in the Northeast Area of Lino Lakes is landlocked, inhibiting site improvements within this area. The area was historically landlocked until the installation of agricultural field drains in the early 20th Century. These agricultural drains are now at capacity and are incompatible with future development within the watershed. In addition, the agricultural drains do not provide any water quality benefits to the receiving waterbody, Peltier Lake. The Northeast area of Lino Lakes (Appendix A, Figure 1) is bound by Main Street to the south, the City of Hugo to the east, and Peltier Lake to the west, and Rehbein Street to the north. The area includes portions of Lino Lakes, Centerville, and Hugo. Land use in this area is predominantly agricultural. A majority of this watershed currently drains to the south to Clearwater Creek via field drains. Clearwater Creek is impaired for aquatic life and has had a history of significant bank erosion problems. Multiple alternatives have been considered to address the surface water needs for this area and are detailed further within this report. The proposed project alternative was refined with input from land owners, potential developers, neighboring communities, the Rice Creek Watershed District (RCWD), the Minnesota Department of Transportation, and the Minnesota Department of Natural Resources. As a condition of the project, a Comprehensive Surface Water Management Plan (CSMP) is in development. The CSMP and the associated surface water modeling includes regional water quality best management practices (BMPs), stormwater volume and rate control improvements, and a new outlet to Peltier Lake. The CSMP also includes design standards for future developments in the Northeast Area. Peltier Lake is impaired for nutrients and it is imperative that the new system does not adversely impact the lake and other downstream interests. The proposed project will benefit nearly 1,300 acres and includes:  A new stormwater conveyance system;  Multi-purpose regional stormwater management facilities;  Pedestrian trail extensions; and  Improvements to Peltier Lake Drive The project will be implemented using a phased approach based on preliminary development patterns. The phases and cost per phase are as follows: Development Phase Cost Phase 1 – Peltier Lake Outlet Improvements $2,248,023 Phase 2 – I-35E Crossing $750,914 Phase 3 – East Side Improvements $639,925 Phase 4 – West Side Improvements $557,491 TOTAL COST $4,196,353
