Comprehensive Stormwater Management Plan <br />Northeast Lino Lakes Drainage Improvement Project <br />WSB Project No. 2929-79 Page 14 <br />4 PROPOSED IMPROVEMENTS <br />The City of Lino Lakes proposed to improve drainage in the Northeast Area by developing a regional <br />stormwater management plan, accomplished through improving stormwater conveyance, adding water <br />quality BMPs, and managing stormwater runoff rate and volume control. The proposed improvements will <br />benefit not only the landowners within the Northeast Area, but also the downstream waterbodies by <br />improving stormwater runoff water quality, increasing to the extent feasible water reuse and irrigation <br />practices, and maintaining existing flood elevations throughout the Rice Creek Chain of Lakes. <br /> <br />The proposed improvements to the CSMP area include: <br /> <br /> Replacement of the existing culvert under Peltier Lake Drive <br /> Open channel system from Peltier Lake Drive to 20th Avenue, including a public greenway <br />corridor with additional water quality features, such as iron-enhanced filtration or biofiltration <br />within the floodplain areas <br /> Regional storage facilities, phased with future developments, to provide flood control storage and <br />additional water quality treatment opportunities <br /> Outlet control structures with gates on selected regional storage facilities to minimize the risk of <br />adversely impacting flood levels on Peltier Lake <br /> New 60-inch storm drain crossing under I-35E to the proposed regional storage facility sited <br />between 20th Avenue and I-35E <br /> Construction of new storm sewer along the future Otter Lake Road extension <br /> Preservation of the agricultural drain tile system to maintain drainage rights until all land within the <br />study area develops. Drain tile may be abandoned or realigned as development progresses, at <br />the benefitted landowners’ expense and discretion. <br /> <br />A conceptual layout and system details are provided in Appendix C. Additional design requirements <br />proposed for land development within the CSMP area are outlined in Sections 6 through 8.
