Haywood Drive terminates in a temporary dead-end to the west, abutting 8024 Wood Duck Trail. This stub provides opportunity for future extension and residential development to Wood Duck Trail. This is consistent with the County Access Management Plan. Haywood Drive also terminates in a temporary cul de sac to the north and provides opportunity for future extension to the north. Street B (Basswood Drive) provides future access to Lino Lakes Elementary School to the east. In 2017, the school began a building remodeling and parking lot reconstruction project. An opportunity to eliminate the school's west driveway and connect with Natures Refuge was identified as a safety benefit. The City and Anoka County are working will continue to work with the school district to complete this connection. Ultimately, it is the school districts decision when to make this connection. Easements Standard drainage and utility easements at least 10 feet wide are provided along all lot lines. Easements at least 20 feet wide are provided over utility pipes. Drainage and utility easements are required 10 feet above the high water level of stormwater drainage ponds and 10 feet outward from the delineated wetland boundary. This requirement is satisfied because easements have been dedicated over the entire outlots. Rear lot lines also have a minimum 10 foot wide easement. A 100 foot wide private utility easement in favor of Great River Energy exists along the southern boundary of the development. Landscaping shall be allowed in the drainage and utility easements covering the 15 foot wide landscape buffer area in Outlot E and Outlot F. Storm Water Management and Erosion and Sediment Control Per the revised Stormwater Management Plan prepared by Carlson McCain dated '7, 2019 December 13, 2021 all of the site's stormwater eventually flows to ACD 32 and to the west. Stormwater leaves the project boundary at two locations: via ACD 32 and a small portion of the property discharges to a ditch along Main Street. The total proposed post -development impervious surface area is approximately 10.4 acres. Soils on the site are classified as Hydrologic Soil Group A/D. Groundwater elevations ranged from 898 feet to 904 feet. The revised Stormwater Management Plan and plan sheets identify four (4) stormwater ponds/lakes, two (2) infiltration basins and Wetland C on site. Wetland C will be enhanced and excavated to provide extended storage of treated stormwater. Pond 100 and Pond 400 are required for stormwater management. Pad Lake 200 and Pad Lake 300 are material excavation ponds. The storm water ponds and trails are located near the wetlands and upland buffers. This strategic design is the basis of the City's greenway system by creating a multi- functional greenway corridor intended to provide areas for stormwater management, upland
