Shingle Creek and West Mississippi Watershed Management Commissions Third Generation Watershed Management Plan CAC Meeting 2 - Implementation

Meeting Purpose Review the proposed Implementation Plan activities ▫Development Rules and Standards ▫Monitoring Program ▫Education and Outreach Program ▫Capital Projects

Rules and Standards Rate of stormwater runoff cannot increase. Runoff must be treated to remove at least 60% of total phosphorus and 85% of sediment. The first ½ inch of runoff must be infiltrated on site, such as in rain gardens, bioinfiltration basins, swales, or capture and reuse. Wetlands and floodplains are protected.

New Development Requirements Current Rules apply to any development project on sites greater than 5 acres; single family residential threshold is 15 acres Proposed Rules apply to any development project on sites greater than one acre

Redevelopment Requirements Current Rules: meet water quality and infiltration requirements only for new impervious surface Proposed Rules: any redevelopment impacting more than 50% of the site must meet all the same rules as new development Proposed Rules: any redevelopment impacting less than 50% of the site must meet the same rules for the entire redeveloped area

Increased Infiltration Requirement Currently must infiltrate ½ inch of runoff within 48 hours Proposed new standard is one inch of runoff in 48 hours Exceptions for clay soils, areas with soil contamination, or wellhead protection areas Bioinfiltration swale, Brooklyn Center

Proposed New Infiltration Credit Get credit towards infiltration requirement Provide soil management in turfed areas on site Decompact soil to 12” in depth Amend top 8” with compost

Monitoring Program To quantify the current status of streams and lakes throughout the watersheds in comparison to state water quality standards. To quantify changes over time, or trends, in stream and lake water quality. To quantify the effectiveness of implemented BMPs throughout the watersheds for the protection of water quality. To document progress toward meeting pollutant load reduction requirements

Monitoring Sites SC-3 Shingle Creek at Brooklyn Blvd Sampled 2007 – Present SC-2 Sampled Approx. 11,000 acres drainage SC-0 Shingle Creek at 45 th Ave Sampled 2001 – Present Approx. 26,000 acre drainage USGS Station Shingle Creek at Queen Ave Sampled 1996 – Present

Water Quality Water quality in Shingle Creek is typical of urban streams in the Twin Cities Metropolitan Area. Shingle and Bass Creeks are currently listed as impaired for chloride, DO and lack of fish and macroinvertebrates. Will be listed in 2014 for E. coli. Shingle Creek may also be considered in the future for TSS and nutrients (TP).

Lake Monitoring

Volunteer monitoring through Citizen Assisted Lake Monitoring Program ▫Proposed in Third Generation Plan: ▫More intensive water quality monitoring ▫Aquatic vegetation surveys ▫Sediment coring Schmidt Lake, Plymouth

Wetland Monitoring Wetland Health Evaluation Program ▫Adult volunteers monitor vegetation and macroinvertebrates (bugs) in wetlands

Macroinvertebrate/Fish Monitoring Commission monitors fish/bugs every 5 years River Watch Volunteer Monitoring ▫High school students ▫3 locations on Shingle Creek ▫1 location on Mattson Brook

Education and Outreach Programming Sponsor volunteer events Participate in education fairs Provide classroom education

New Program – “Green Yard” Still being conceptualized Individual stormwater management plan Reduce fertilizer and pesticide useIncrease composting Improve turf maintenance Use native vegetation

Other Education and Outreach What things would you like the Commissions to take on?

Projects

Intensive BMP Studies Planning for small BMPs Detailed analysis by subwatershed ID cost-effective BMPs on a neighborhood or site scale Stormwater Retrofit Protocol-Metro Conservation Districts

Capital Projects TMDLs identified several capital projects Cities incorporate projects into their own capital improvement program, street reconstruction program Commission can cost share in 25% of implementation cost up to $250,000 per project Commission partners to obtain grants for projects
