4.6 Shorelines and Streambanks
Goal 6 - Shorelines and Streambanks
Preserve the natural appearance of shoreline areas and minimize degradation of surface water quality which can result from dredging operations.
Eroding shorelines and streambanks contribute to the degradation of water quality. Native vegetation can effectively stabilize these areas, filter runoff for sediment and other pollutants, and provide habitat. Restoration of shoreline and streambanks on Christmas Lake, especially the steep slopes on the eastern shore; the channel draining the upper subwatershed; and wetlands within the subwatershed is a key strategy for meeting this plan’s goals.
Conservation or restoration of native vegetation along shoreline and streambank would provide habitat for both aquatic and terrestrial wildlife; help increase or maintain infiltration rates; decrease or maintain runoff rates and pollutant conveyance to water resources; and help minimize erosion. Sustaining or improving water quality and ecological integrity is necessary to meet District goals as well as to meet state and federal nondegradation, water quality and biological integrity requirements and to prevent the need for future TMDLs.
Desired Outcomes: Stable streambanks and shorelines to supplement other goals.
Metrics: Linear feet of stabilized eroded shoreline and streambank.
Goal 6.1 - Christmas Lake
Promote shoreline restoration and shoreline buffer creation as methods to help meet pollutant loading reduction and ecological integrity goals.
Conduct a Christmas Lake shoreline vegetation survey to identify current shoreline status and to identify locations where restoration may be desirable and feasible.
Work cooperatively with the City of Chanhassen to identify and complete potential restoration opportunities along the channel that drains the upper subwatershed.
Promote native vegetation over structural shoreline stabilization in District policies, regulations, and programs.
Provide education and training opportunities, technical and planning assistance, and demonstration project funding to LGUs to assist them in restoring shorelines and buffers on public property such as parks and open spaces.
Develop and distribute written material to shoreline property owners explaining the benefits of shoreline restoration and buffer creation to the reduction of pollutant loads and creation of shoreline habitat and providing design, plant selection, installation, and maintenance advice.
Develop a small grant program to provide financial assistance to property owners desiring to restore their shoreline or plant a buffer.
