Feasibility Report Northeast Lino Lakes Drainage Improvement Project WSB Project No. 02029-790 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 has been historically landlocked until the installation of agricultural field drains in the early 20th century. These systems of agricultural drains have limited capacity, and as such, cannot convey any additional runoff from development within the watershed. The agricultural drains also do not provide any water quality benefits. 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. It 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 via field drains to Clearwater Creek. Clearwater Creek is impaired for aquatic life and has had a history of significant bank erosion problems. There were multiple alternatives considered to address the surface water runoff needs for this area as detailed further within this report. These options were coordinated with the Rice Creek Watershed District (RCWD) and a draft Comprehensive Surface Water Management Plan (CSMP) was created. The CSMP and the associated surface water modeling included water quality best management practices (BMPs), volume and rate control improvements, and a new outlet to Peltier Lake. Peltier Lake is impaired for nutrients and a new system would significantly reduce the agricultural loading to the lake. The proposed project will result in a regional storm water conveyance system for 1,400 acres that will allow for development that includes:  Reginal storm water treatment  Storm water quality and rate control 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 Pipe $2,114,944 Phase 2 – I-35E Crossing $689,030 Phase 3 – Otter Lake Trail Storm Sewer Extension $1,244,986 Phase 4 – Future Improvements $690,824 TOTAL COST $4,739,784 Funding for the project will be through surface water management fees, and potential grants from Rice Creek Watershed District (RCWD), Minnesota Board Water and Soil Resources (BWSR), and the Public Facilities Authority (PFA). This project is feasible, necessary, and cost-effective from an engineering standpoint and should be constructed as proposed herein.
