Anoka Soil Water Conservation District/Rice Lake Stormwater Retrofit/Nate Zwonitzer Mr. Nate Zwonitzer from Anoka County Conservation District gave a presentation to the Environmental Board members on the Rice Lake Stormwater Retrofit Proposal. Retrofit Goals consist of: Reducing the volume and pollutant load entering water body of concern. Identify pollutant "hot- spots" within subwatershed: Prioritize neighborhoods and project sites to maximize treatment per dollar spent and to install retrofit projects. Ms. O'Dea questioned why we want to reduce water. Mr. Zwonitzer stated when you introduce impervious surfaces through new developments, we want to change the way the water travels, not reduce it. Step 1: Retrofit Scoping = Screen for retrofit potential, define retrofitting objectives and identify preferred treatment options. Step 2: Desktop Retrofit Analysis = Gather maps of stormwater practices, conduct desktop search for retrofit sites and Prepare base maps. Step 3: Retrofit Reconnaissance Investigation = Verify stormwater mapping and Investigate Feasibility of Retrofit Sites. Step 4: Retrofit Evaluation and Ranking = Compute volume and pollutant reductions, compare results with restoration objectives and rank retrofit projects according to effectiveness and cost. Step 5: Subwatershed Treatment Analysis = (Evaluation and Ranking) Conduct neighborhood consultations, develop retrofit screening criteria and create retrofit project priority list. Step 6: Finalize Designs = Obtain landowner approval, conduct bidding for construction and assemble design packages. 2 DRAFT MINUTES • • ENVIRONMENTAL BOARD MEETING FEBRUARY 25, 2009 • Step 7: Construction: Oversee BMP Installation. Conduct pre - construction meetings and Inspect construction progress. • Step 8: Inspection, Maintenance and Evaluation = Provide maintenance training to landowners and continued project tracking and monitoring. Other Retrofit Types: Pond modification Roadway crossing storage Conveyance system treatment Parking Lots Individual streets Underground Ms. O'Dea questioned who will pay for this? Mr. Asleson stated landowner cooperation, cost share funds from Anoka County and State of Minnesota. Mr. Asleson stated we don't have a stormwater utility fund at this time. Ms. Bor questioned if there would be a tax break. Mr. Zwonitzer stated there is cost share available up to $5,000. Ms. Bor questioned if this is a collaboration with the Rice Creek Watershed District. Mr. Zwonitzer stated yes. Mr. Brown questioned if residents could use pavers for their driveways. Mr. Zwonitzer stated yes, but a very expensive option. The cost is $20 -$25 per square foot. Mr. Zwonitzer stated if a resident was redoing their driveway, they could install a trench grate which is flush with the new asphalt driveway and a rain garden connected to that. Mr. Asleson stated if Mr. Zwonitzer would come back when this project is further along. Mr. Zwonitzer yes. B. Updates Recycle Bank Mr. Asleson received information from Allied Waste regarding a RecycleBank program. He reviewed the information with the board.

Transcribed by: Lisa Hogstad Community Development Secretary 4 DRAFT MINUTES • • AGENDA ITEM 5-A STAFF ORIGINATOR: Tim Payne, Natural Resources Specialist MEETING DATE: April 29, 2009 TOPIC: Public Hearing: Annual Storm Water Pollution Prevention Program VOTE REQUIRED: N/A BACKGROUND: In compliance with the provisions of the Clean Water Act, as amended, (33 U.S.C. 1251 et. Seq., 40CFR 122, 123 and 124, as amended et seq.); Minnesota Statutes Chapters 115 and 116, as amended, and Minnesota Rules Chapter 7001, the city adopted a Storm Water Pollution Prevention Plan (SWPPP) and authorized its submittal to the Minnesota Pollution Control Agency as part of the City's application for enrollment in the State of Minnesota's General National Pollution Discharge Elimination System Phase II Permit Authorizing the City's discharge of storm water. As part of the SWPPP, the City must solicit public input at an annual meeting required under the Public Education and Outreach Plan including: • A presentation about implementation of the City's Surface Water Pollution Prevention Program in 2008. • Affording interested persons an opportunity to make oral statements concerning the Storm Water Pollution Prevention Program. • Consideration of relevant written materials that interested persons submit concerning the Storm Water Pollution Prevention Program. • Consideration of public input in making adjustments to the 2009 implementation plan for the Storm Water Pollution Prevention Program. ANALYSIS: According to the 1996 National Water Quality Inventory, stormwater runoff is a leading source of water pollution. Stormwater runoff can harm surface waters such as rivers, lakes, and streams which in turn cause or contribute to water quality standards being exceeded. Stormwater runoff can change natural hydrologic patterns, accelerate stream flows, destroy aquatic habitats, and elevate pollutant concentrations and loadings. Development substantially increases impervious surfaces thereby increasing runoff from city streets, driveways, parking lots, and sidewalks, on which pollutants from human activities settle. Common pollutants in runoff include pesticides, fertilizers, oils, metals, pathogens, salt, sediment, litter and other debris are transported via stormwater and discharged — untreated — to water resources through storm sewer systems. The Stormwater Program for Municipal Separate Storm Sewer Systems (MS4's) is designed to reduce the amount of sediment and pollution that enters surface and ground water from storm sewer systems to the maximum extent practicable. Stormwater discharges associated with MS4's are regulated through the use of National Pollutant Discharge Elimination System (NPDES) permits. NPDES permits are legal documents. Through this permit, the City is required to develop a Stormwater Pollution Prevention Program (SWPPP) that incorporates Best Management Practices ( BMP's) applicable to their MS4. Below is a list of the accomplishments of the City of Lino Lakes in implementing identified best management practices ( BMP's). 2008 Best Management Practice Implementation and Accomplishments: Public Involvement • Storm Drain Stenciling: The City of Lino Lakes solicited volunteers to work with RCWD to stencil/label storm drains. Public awareness was represented by the placement of storm drain buttons on 136 storm drains. • Stream Monitoring: Partnering with Stream Health Evaluation Program (SHEP), and had volunteers from the community monitoring Hardwood Creek, Rice Creek and Clearwater Creek. • Stream Cleanup: Assigned several groups to clean up creek and tributary areas in the City of Lino Lakes on Earth Day. • Quarterly newsletter articles on residential clean-water initiatives to increase public involvement in the following: resident BMP's for their property to improve surface water runoff quality including pet -waste management, soil management, irrigation management, water conservation, and impervious surface management. • Distributed a Lino Lakes Recyclopedia that lists all of the appropriate recycling locations, vendors for different products including hazardous waste. • Prepared a display on recycling and good housekeeping practices for homeowners at Earth Day. • Maintained a kiosk of information on environmental issues such as recycling, water quality improvement, forestry issues, and NPDES Phase II/MS4 fact sheets for residents. • Held an Arbor Day Celebration at Lino Lakes Elementary and hosted Tricia and the Toones who tailored their entertainment/presentation to recycling and importance to clean water issues. • Became members of Blue Thumb with the Rice Creek Watershed District (RCWD). • Worked on environmental education curriculum with the Centennial School District. • Maintained a page on the City Website related to NPDES for MS4's and Best Management Practices for residents. Illicit Discharge Detection and Elimination • Continued to maintain and update a GIS map and spatial database of the City's storm sewer system. • • • • The City is implementing a Regulatory Control Program and Illicit Discharge Detection and Elimination. • The City continues to work with Rice Creek Watershed district on Illicit discharge education for residents. • City employees continue to attend and maintain NPDES certifications from the State of Minnesota. • The City of Lino Lakes has begun the implementation of recommendations within the Minnesota Department of Health - Wellhead Protection Plan. Construction Site Stormwater Runoff Control • The City of Lino Lakes has adopted the following Ordinances Ordinance 03 -08 Section 3 Subd. 4 L & Subd. 11.; Subdivision Ordinance 04 -03; Surface Water Management Plan Adopted December 2005. The City is evaluating revisions to the above regulatory mechanisms and considering creation of a new ordinance. • The City performs regular site inspection of all construction sites under NPDES permits. • The City also regularly monitors resident activities not under the jurisdiction of NPDES requirements to ensure proper stormwater runoff control. Post - construction Stormwater Management in New Development and Redevelopment • The City monitors post construction runoff through regular site inspections. • The City maintains structural and non - structural BMP's through requirements on the construction of detention ponds (structural) and drainage swales (non - structural). Pollution Prevention and Good Housekeeping for Municipal Operations • Continue to train City Staff. • The City sweeps all impervious surfaces twice a year. Street sweepings occur in early spring as weather allows and again in the fall after leaf off and prior to hydrant flushing. • The City annnally inspects all structural pollution control devices such as trap manholes, grit chambers, sumps, and other settling or filter devices and retains inspection information. • The City inspects 20% of the MS4 outfalls, sediment basins and ponds each year and retains inspection information. 2009 Best Management Practice and Implementation Goals: • Continue to utilize a full time NPDES inspector. • Public education will be emphasized in 2009. • Educate the general public through pamphlets or mailings. • Educate contractors about site erosion and mitigation practices. • Promote school or volunteer organizations participation. • Educate City employees to identify improper disposal of waste. Attached are the following figures: 1. The Storm Sewer Inspection Map shows the inspections completed over the last five years throughout the City. 2. The 2008 Surface Water Management Project Location Map. 3. The Storm Water Inspection Form is used by the full -time NPDES Inspector for response to complaints or to document any maintenance work. RECOMMENDATION: Staff recommends closing the public hearing. • • • STORM SEWER PIPES inspection -areas 0 0 0 0 N N N N APRIL 29, 2009 Mn.0.11.11.11■ 1. 0 .11.11.1.11.11 MUM 11 .11 .11.11 ■11.11 .11.11.11.11 ■11.1.1 /.0.n.1/.IM H11.1.11.11.11.0.11.11. 11. 11■UNI 1.11..11.11.11.11 .11.11.11.11.11.11.11.11.11. ■ ■ • are II.n.n.n.u.nnI.u.n.u.na t.1,.II.,I.It ■II.II. i mum 1.11.11.
