• Delineation of sub -watershed boundaries and land use determinations for each lake studied • Listing of current impairments for the 24 lakes studied • Summary of available lake quality data • Recommendations for additional lake quality monitoring via the Metropolitan Council's Citizen Assisted Monitoring Program (CAMP) • Identification of available in -lake and watershed BMPs to address impairments of the lakes studied The report identified Spring Lake as a shallow basin due to a littoral area that encompasses more than 95% of the lake. The existing lake quality data for Spring Lake was limited, with only one full year of sampling data available at the time the report was written. The report recommended that Spring Lake be added to the CAMP in 2008 to begin to compile additional lake quality data. The report also notes that Spring Lake has experienced significant water level fluctuations in the recent past. New data could provide insight into the level of impact the water level fluctuations are having on lake quality. Phase II of the report focused on soliciting input from lake stakeholders to identify any "impairments" to the beneficial uses they identified. This phase used the existing lake quality data and identified impairments to develop MAPS for each of the 24 lakes studied. The MAPS included a discussion of water quality, public input, and recommendations regarding data collection and specific BMPs to address impairments. 4.4 STREET AND UTILITY IMPROVEMENT PROGRAM (SUIP) As identified in the City's 2008-2009 Action Plan, the City implemented the Street and Utility Improvement Program (SUIP). The basis for this program followed the recommendations of the Streets and Utilities Task Force: Reconstructed or rehabilitated all streets within 9 years. No assessments to individual property owners. The City financed the SUIP in part by a tax levy on all properties. Adopted a uniform street standard making engineering of individual projects straightforward. Recommended standards included: o Structurally strong street section with durable concrete barrier -style curbs. o Repaired and upgraded water mains and sewers. o Considered sidewalks or trailways where indicated in the City's Comprehensive Sidewalk/Trailway Plan. o Applied the most cost-effective stormwater management practices to comply with RCWD Rules; this generally meant rain gardens or infiltration swales. o Group mailboxes in accordance with Municipal Code. Significant flexibility to accommodate individual property owners needs remained. Information about the SUIP can be found on the City's website. 4.5 STORMWATER INFILTRATION PROGRAM (SIP) To address the RCWD volume control requirements for the SUIP areas, the City implemented a program that approached volume control for all projects in a uniform and cost-effective manner. The City Council adopted a resolution establishing the Stormwater Infiltration Program (SIP) to provide a uniform and City of Mounds View 21 Local Surface Water Management Plan Stantec Project No. 193804166 5 5tantec
