• • 1 1 Attachment 1: Site Layout Performance Standards Page 3 ii. Wetland Preservation Corridor. Establish the WPC in accordance with watershed district rules. The delineated WPC will be established during the site planning process. iii. Vegetated Wetland Buffer. Establish an upland buffer of native vegetation around wetlands within the WPC to maintain water quality and habitat. Development is regulated in the following manner: (a) The buffer shall average at least 50 feet in width, measure at least 25 feet at all points, and meet the average width at all points of concentrated inflow. The location of the buffer shall maximize the protection of ESAs. (b) The vegetated wetland buffer and upland habitat area must meet the requirements in RCWD RMP -3 and the Vadnais Lake Area Water Management Organization, as amended (c) Structures shall be setback a minimum of 10 feet from the edge of the wetland buffer. iv. Natural and Semi- Natural Areas. Conserve and enhance the function and value of these areas for habitat, water quality, surface water management, aesthetics, and passive recreational use. (a) Suitable habitat for rare, threatened, or endangered species shall be protected to the extent practical. (b) The Lcvcl Two (T 3) tree preservation and mitigation requirements in Section 3. Subd.4.Q shall apply to Natural Resource Protected Areas. (c) Prairie and other non -woody natural and semi- natural communities shall be considered for protection, restoration, and /or inclusion in the surface water management system. (d) Structures shall be setback a minimum of 10 feet from the edge of protected natural and semi - natural areas. b) Natural Resource Conservation Areas. These areas shall be conserved to maintain the function and value of the area while allowing encroachment and disturbance to accommodate development. Specific performance standards within a Natural Resource Conservation Area are as follows: i. Natural and Semi- Natural Areas. Conserve and enhance the function and value of these areas for habitat, water quality, surface water management, aesthetics, and passive recreational use. (a) Suitable habitat for rare, threatened, or endangered species shall be protected to the extent practical. (b) The Lcvcl Two (T 2) tree preservation and mitigation requirements in Section 3. Subd.4.Q shall apply to Natural Resource Conservation Areas. (c) Prairie and other non -woody natural and semi- natural communities shall be considered for protection, restoration, and /or inclusion in the surface water management system.
