6 <br /> <br />Storm Water Management and Erosion and Sediment Control <br /> <br />Per the revised Stormwater Management Plan prepared by Carlson McCain dated June 7, 2019, <br />all of the site’s stormwater eventually flows to ACD 32 and to the west. Stormwater leaves the <br />project boundary at two locations: via ACD 32 and a small portion of the property discharges to <br />a ditch along Main Street. The total proposed post-development impervious surface area is <br />approximately 10.4 acres. <br /> <br />Soils on the site are classified as Hydrologic Soil Group A/D. Groundwater elevations ranged <br />from 898 feet to 904 feet. <br /> <br />The revised Stormwater Management Plan and plan sheets identify four (4) stormwater ponds, <br />two (2) infiltration basins and Wetland C on site. Wetland C will be enhanced and excavated to <br />provide extended storage of treated stormwater. Pond 100 and Pond 400 are required for <br />stormwater management. Pond 200 and Pond 300 are material excavation ponds. The storm <br />water ponds and trails are located near the wetlands and upland buffers. This strategic design is <br />the basis of the City’s greenway system by creating a multi-functional greenway corridor <br />intended to provide areas for stormwater management, upland buffers for wetland protection <br />and natural resource conservation, and open space and trails for people. <br /> <br />A maintenance access trail is provided around Pond 200. This access trail will be graded, but <br />will not require gravel or paved improvements. <br /> <br />The site will be mass graded in one (1) phase. Residential home development will occur over <br />several years. <br /> <br />Utilities <br /> <br />Public water, sanitary and storm sewer utilities will be installed within the development. <br /> <br />Sanitary Sewer <br /> <br />A 21” trunk sanitary sewer main located along CSAH 14 (Main Street) serves the site. An 8” <br />and 10” sanitary sewer pipe serves the site internally. Future development to the north will <br />potentially require a lift station. Sanitary sewer will also be stubbed to the west to <br />accommodate future development. <br /> <br />Watermain <br /> <br />A 12” trunk watermain located along CSAH 14 (Main Street) serves the site. An 8” and 16” <br />watermain serve the site internally and loops the system to CSAH 14 (Main Street). Watermain <br />will be stubbed to the west and north property boundaries for future development. <br /> <br />Public Land Dedication <br /> <br />The City will require cash in lieu of land dedication. Per the City’s Park, Greenway & Trail <br />System Plan, a neighborhood park is not programmed for this area. Lino Lakes Elementary <br />School is immediately adjacent to the development.
