<br /> <br /> <br />Feasibility Report <br />Northeast Lino Lakes Drainage Improvement Project <br />WSB Project No. 02029-790 Page 10 <br />event and will need to be planted with a suitable planting palette that can tolerate periodic <br />inundation to maintain vegetation. <br /> <br />4.4. Storm Water Quality <br /> <br />The study area will include a variety of measures to provide treatment and improve water quality <br />in Peltier Lake and the Anoka Chain of Lakes to minimize impacts related to this project. All <br />individual developments will be required to manage stormwater on site to the current and <br />applicable Rice Creek Watershed District rules. It is anticipated the study area will include a <br />water quality treatment train with sedimentation BMPs located in upland areas, designed to <br />remove solids and particulate matter, combined with surface and media filtration to remove <br />dissolved particulates, nitrogen and phosphorus, prior to entering the new storm sewer. <br /> <br />The existing and proposed total phosphorus loading from the study area to Peltier Lake were <br />evaluated at a conceptual level, using event mean concentrations from the Minnesota Stormwater <br />Manual for the general land use types within the study area. <br /> <br />While the development of the study area would result in increased total phosphorus loading to <br />Peltier Lake by about 16 pounds annually, without treatment, the City of Lino Lakes and RCWD <br />required water quality treatment practices will actually reduce the total phosphorus loading to <br />below existing conditions. <br /> <br />Refer to APPENDIX D for details and design requirements for the study area. <br /> <br />4.5. Permits and Approvals <br /> <br />Construction of the pipe and outlet will disturb more than one acre of land and will require a <br />National Pollution Discharge Elimination Systems (NPDES) General Stormwater Permit [MNR <br />100001] that must be obtained by Lino Lakes from the Minnesota Pollution Control Agency <br />(MPCA). <br /> <br />The project includes a new outlet to Peltier Lake, as such the City will need to obtain a DNR <br />Public Waters Work permit (GP2004-0001) from the MnDNR, as well as obtain a Rice Creek <br />Watershed District [RCWD] permit to demonstrate no adverse impacts will be created as result <br />of this project. <br /> <br />The project also includes a culvert crossing under I-35E; as such the City will need to obtain a <br />Utility Accommodation on Trunk Highway Right of Way Permit (Form 2525) and a <br />Miscellaneous Work on a Trunk Highway Right of Way permit (Form 1723) from MnDOT. <br /> <br />The project includes a storm drain crossing under 20th Avenue (CSAH 54), a Right of Way <br />Permit from Anoka County may be required. <br /> <br />The storm water conveyance alignment has been chosen to avoid or minimize wetland impacts; <br />however any modifications to existing wetlands would require approval by the Technical <br />Evaluation Panel (TEP). <br />
