also make an in-kind or a monetary contribution to the development and maintenance of community storm water management facilities designed to serve multiple land disturbing and development activities undertaken by one or more persons, including the applicant. B.) All calculations and hydrologic models/information used in determining peak flows Must be submitted along with the storm water pollution control plan; C.) The applicant shall consider reducing the need for storm water management facilities by incorporating the use of natural topography and land cover such as natural swales and depressions as they exist before development to the degree that they can accommodate the additional flow of treated (e.g., settled) water without compromising the integrity or quality of the wetland or pond. (Commentary: The sensitivity of a wetland to degradation varies with the type of vegetation. Sedge meadows, open bogs and swamps, coniferous bogs, calcareous fens, low prairies, lowland hardwood swamps, and seasonally flooded basins are highly sensitive to degradation, while flood plain forests, reed canary grass meadows, shallow (reed canary grass, cattail, giant reed or purple loosestrife) marshes are only slightly sensitive to degradation. See the current version of the Minnesota Pollution Control Agency's publication "Storm-Water and Wetlands: Planning and Evaluation Guidelines for Addressing Potential Impacts of Urban Storm-Water and Snow-Melt Runoff on Wetlands "for details.) D.) The following storm water management practices must be investigated in developing the storm water management part of the storm water pollution control plan in the following descending order of preference: 1.) Protect and preserve as much natural or vegetated area on the site as possible, minimizing impervious surfaces, and directing runoff to vegetated areas rather than to adjoining streets, storm sewers and ditches. 2.) Flow attenuation by use of open vegetated swales and natural depressions; 3.) Storm water wet detention facilities (including percolation facilities); and 4.) A combination of successive practices may be used to achieve the applicable minimum control requirements specified in subsection (A) above. The applicant shall provide justification for the method selected. 6.6 Minimum Design Standards for Storm Water Wet Detention Facilities. These facilities must conform to the most current technology as reflected in the current version of the Miiiriesota Pollution Control Agency's publication, "Protecting Water Quality in Urban Areas" and the current requirements found in the same agency's NPDES permits for storm water associated with construction activities. 6.7 Minimum Protection for Natural Wetlands. 13
