shrubs, and trees would both intercept runoff from the lot and enhance wildlife habitat. The LID could host <br />workshops and provide educational materials for property owners on the ecology of natural shorelines and could <br />initiate pilot projects on the shorelines of willing property owners to demonstrate the concept and benefits. <br />Factors and conditions that improve shoreline buffer effectiveness include: <br />- Width of buffer (as width increases effectiveness increases; buffers > 50 feet preferred) <br />- Slope to water (slopes less than 3:1 increase effectiveness) <br />- Soil type (sandier soils encourage infiltration) <br />- Type and amount of land -disturbing activities and impervious surfaces near the buffer <br />- Use of pesticides and fertilizers <br />- Presence of pet wastes <br />- Trees and shrubs with extensive roots within the buffer (a healthy, naturally vegetated buffer is preferred) <br />- Presence of organic matter within the buffer <br />- Runoff velocity (lawns have higher runoff rates and volume) <br />DNR strongly encourages the LID to include natural shoreland restoration and installation of buffers as a component <br />of its phosphorus reduction strategy. DNR also strongly encourages the LID to consider working with BWSR's Lawns <br />to Legumes program, which encourages native plantings for pollinator habitat, and Blue Thumb, which promotes <br />native plantings to improve water quality. Both organizations host workshops, provide advice on plantings, and <br />have grant programs. <br />Proposed LID Boundaries <br />The boundaries of the proposed LID include properties with direct or deeded access to the bay. MR Part 6115.0920 <br />subpart 5 requires that the boundaries include all lands and waters within the direct drainage basin of the lake <br />(shown on the attached map). However, this rule also allows the County Board or City Council to create a boundary <br />less than the entire drainage basin with written Commissioner approval if the boundary selected includes a sufficient <br />amount of the lake's watershed to develop and implement feasible solutions to the problems the LID intends to <br />address. Restriction of the district's boundary to these properties is sufficient to address the in -lake activities for <br />which the LID is being proposed. Therefore, in accordance with these rules, the DNR approves the proposed <br />boundaries identified in the resolution. <br />282 <br />
