Wetlands. "Wetlands" means lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water. For purposes of this definition, wetlands must have the following three attributes: ( ) have a predominance of hydric soils; ( )are inundated or saturated by surface or ground water at a frequency and duration sufficient to support a prevalence of hydrophytic vegetation typically adapted for life in saturated soil conditions; and ( ) under normal circumstances support a prevalence of such vegetation. (MN Statutes 103.G.005) 157.02. Purpose The City has a strong interest in protecting and managing its valuable water and natural resources, recognizing the relationships between resource protection, land use management, development, redevelopment and fiscal responsibility. Federal and State regulations have placed restrictions and requirements on the management and discharge of stormwater with which the City must comply. The CityÓs Local Surface Water Management Plan (LSWMP) established goals and policies to meet those regulations. The City provides requirements for stormwater management on development and redevelopment projects to ensure the CityÓs goals and policies are met and that there is compliance with federal, state, and local rules. The City recognizes in its Surface Water Management Plan that Rice Creek Watershed District (RCWD has primary responsibility for stormwater management permits within the City, and staff is authorized to defer to RCWD in permit review and enforcement. 157.02-157.03 Reserved Post-Construction Stormwater Management 157.2004 Stormwater Management Plan (A) General Criteria. A stormwater management plan shall be required of all new development, redevelopment and land disturbance projects greater than one (1) acre in parcel size or part of a greater plan of development. This plan shall be designed to reduce and/or minimize the impervious area of the site, control the peak flow rate, and minimize the volume of stormwater runoff from the same as required in the LSWMP and this Code. Plans must be submitted to the City for review and approval prior to the start of construction. Each project will construct, implement and maintain all best management practices (BMP) that are deemed necessary to achieve the goals of this Chapter, including post-construction stormwater management BMPs. Prior to the start of construction, all projects shall be in possession of any and all permits required for the project including, but not limited to: 1. Rice Creek Watershed District, 2. City of Centerville, 3. U.S. Army Corps of Engineers, 4. National Pollutant Discharge Elimination System (NPDES), and 5. Wetland restoration or mitigation plan approval. Projects smaller than one (1) acre in size are encouraged to implement BMPs that will promote infiltration and contribute to improved water quality. The City reserves the right to require erosion prevention measures to land-disturbing activities of less than one acre, when in the judgment of the CityÓs Public Works Director, the land disturbing activities are likely to result in discharge of sediment or other pollution into the CityÓs stormwater system, or into Waters of the State. 157.05 157.21 Design Standards. Minimal Impact Design Standards (MIDS) shall be followed to achieve the best stormwater management. The 416 |Page
