45 City of St. Anthony Village Planning Commission September 8, 2003 Page 4 hearing. This will include a presentation of a drawing which shows a straight line view, from Silver Lake Road, toward the parking lot edge and on to the Discount Retail building, as requested by the Planning Commission. This will include a realistic representation of the parking lot landscaping in the short term. The developer will also present additional elevations of typical retail building clusters. EROSION CONTROL • 1 The City is concerned about water quality of Silver Lake, and the developer proposes to take steps as a part of the site construction to prevent erosion and the discharge of sediment off--site and into the lake. As a condition of approval, the developer will be required to obtain a National Pollution Discharge Elimination System (NPDES) permit and a Rice Creek Watershed District (RCWD) permit. The NPDES is regulated by the Minnesota Pollution Control Agency and includes guidelines and requirements that the developer will follow to reduce sediment discharge off the construction site. The RCWD reviews development and grading plans through their permitting process. The developer will be detailing the erosion control plans for the site through these permitting processes. The developer will use Best Management Practices (BMP's) to prevent sediment discharge, include the following: • The construction and maintenance of on-site temporary sedimentation basins to intercept storm water runoff before discharge off-site. In particular, the treatment of runoff prior to discharge into the existing pond between Cub Foods and the Equinox apartments will be key in reducing the off-site discharge of sediment. The site work schedule will include the construction of temporary stormwater ponds at the beginning or construction before major areas are exposed. • Expanding the existing sedimentation basin and the addition of another stormwater pond will compensate for the new construction on the site. • Perforated riser pipe outlets in temporary sedimentation basins will help reduce the amount of sediment leaving the site. • Restoration and turf establishment through seeding and mulching and other BMP's according to the NPDES schedule. • Limiting the exposed soil area of the site. • Silt fence installation around the perimeter of the site and around permanent ponds as they are completed. • Inlet protection for storm sewer inlets as they are installed. Rock construction entrance(s) will be used to help prevent sediment from tracking onto adjacent streets. • Routine street cleaning and sweeping of adjacent streets to collect sediment tracking. As construction plans are developed, the BMPs listed above, and potentially other BMPs, will be
