These BMPs include a rock construction entrance, silt fence (including redundant silt fence in the proximity of the wetland to the northwest), inlet protections, and riprap for energy dissipation at pipe outfalls. The infiltration basin, rain guardian, and forebay will provide pre-treatment of stormwater. Being that this site will drain to an impaired water, Rice Lake, stabilization of exposed soil areas must occur within 7 days after the construction activity in that area permanently ceases. Flood Plain Site does not fall within the flood management zone. Shoreland District Site falls within Shoreland District. This will impact setbacks, lot widths, design criteria for structures, and other factors that will be reviewed by Planning, Engineering, and Building staff. There are limitations on vegetation alteration in the Shoreland District, but the alterations in this case are related to construction and uses permitted in the zoning district, which are exempt from these limitations. Impervious surface must not exceed 60%. This proposed project includes approximately 25% impervious surface. Greenway System The wetland on the site is noted in the Greenway System, due to inclusion in the Wetland Management Corridor, which classifies it as Natural Resource Conservation Area. Being that there are no impacts proposed to this wetland and that a future proposed trail would be in the County right-of-way on Hodgson Road, there are no additional Greenway System related concerns for this site. Wetlands Per the Wetland Delination Report, a 0.015 acre wetland area was delineated within the project area. This wetland meadow/shrub swamp was dominated by reed canary grass (Phalaris arundinacea) and tussock sedge (Carex stricta). No impacts to this wetland are proposed. This wetland is part of the Wetland Management Corridor, so a vegetated buffer with an average of 50 ft. and a minimum width of 25 ft. will be required per Rice Creek Watershed District rules. M
