• Must be no less than 16.5 -feet wide upland from the wetland boundary. • Must be present where ever land disturbance is occurring within 100 feet up -gradient of the wetland boundary. • Must not be graded or disturbed. • Must be demarcated by a properly installed heavy duty silt fence. Fiber logs or other continuous temporary erosion measures may be used if approved by the LRRWMO and/or the City. All erosion control measures must be installed and inspected prior to initiating any site disturbance activities. These materials must be in place throughout the construction process, including land grading and building. • May be accomplished by installation of erosion control around the perimeter of land disturbance used to satisfy LRRWMO, city, or state erosion control rules provided it is consistent with the other specifications listed in this section. • May be encroached upon for: o Activities associated with planting native vegetation or management to favor native vegetation. Encroachment for establishing turf grass is not allowed, EXCEPT AS SPECIFIED BELOW: o The installation of stormwater conveyances, such as outfalls, or grading necessary for hydrologic safeguards, such as emergency overflows. If portions of a wetland are to be lawfully filled or drained during the construction process through a MN Wetland Conservation Act permit, the area of wetland protections shall be placed at that new wetland boundary. In this case it does not make sense to place the silt fence 16.5 feet from the new wetland boundary, because this would be within the area that is being filled or drained. Instead, the protections should be placed at the new wetland boundary. This applies only to the portion of the wetland edge where lawful wetland impact will occur during the construction process. The provisions listed above apply until construction (including grading and building) is complete, the site is stabilized, and vegetation has been established in the project area. Native Plant Seeding in Common Spaces at the Conclusion of Construction Within common spaces, areas adjacent to wetlands that are disturbed through the construction process and ponding areas (stormwater management areas) should be seeded with a MN Board of Water and Soil Resources (BWSR) native seed mix which matches site conditions. Common spaces include outlots, areas transferred to city ownership, homeowners association common space, and similar. This seeding should be done as part of site stabilization following construction. Site preparation and seeding should be consistent with BWSR guidance. The extent of seeding around wetlands shall be reviewed by the LRRWMO Board and determined on a case by case basis. Decision making will be based on the following guidance: Comprehensive Watershed Management Plan Lower Rum River Watershed Management Organization October 2011 G-5
