Ms. Katie Larsen <br />June, 2, 2016 <br />Page 2 <br /> <br /> <br /> S:\Community Development\Projects\Planning Cases\St. Clair Estates\Staff Reports\20160608 PZ (PP-Variance)\4 20160602 Engineering Review Lino Lakes-St <br />STORMWATER MANAGEMENT <br /> <br />We reviewed the Stormwater Drainage Report for St. Clair Estates, dated May 9, 2016, and <br />provided by Plowe Engineering, Inc. and have the following comments: <br /> <br />1. Rate control is being met. <br /> <br />2. All water quality requirements are being met. <br /> <br />3. The stormwater management design and calculations need to be updated and re- <br />submitted with the proposed changes for review. We do not anticipate any significant <br />changes to the proposed layouts with relation to the storm sewer system. <br /> <br />4. The side yard storm sewer on narrow lots needs to be coordinated with the building plans. <br />No overhanging windows or window wells can be installed. A clear 20 feet needs to be <br />provided. The applicant shall provide a summary of side yard storm sewer with pipe <br />depths and a summary of how future access for maintenance will be accommodated. <br /> <br />FLOODPLAIN <br /> <br />1. Project affects the FEMA floodplain at Outlot B. The applicant shall obtain a Letter of <br />Map Revision and provide the application to City. <br /> <br />WETLANDS <br /> <br />The City of Lino Lakes is not the Local Government Unit (LGU) for the Wetland Conservation <br />Act (WCA), therefore, regulatory WCA comments are not provided here as the Rice Creek <br />Watershed District will be the LGU to review and approve the wetland delineation. <br /> <br />1. Provided the LGU approves the wetland delineation, there are no proposed wetland <br />impacts. Therefore, no wetland mitigation approval is needed. <br /> <br />2. Wetland buffers are shown on the plan set. The RCWD will have regulatory authority <br />over review and approval of the wetland buffer. <br /> <br />3. A conservation easement is recommended for parcels adjacent to the lake to protect the <br />buffer area. <br /> <br />ENVIRONMENTAL <br /> <br />1. No comments at this time. <br /> <br />WATER SYSTEM <br /> <br />1. Reference the City’s 2016 General Specifications and Standard Detail Plates for Street <br />and Utility Construction with the Final Plat and plan submittal.
