4. An assessment of existing or potential water resource -related problems. At a minimum, the plan should include: - A prioritized assessment of the problems related to water quality and quantity in the community. - A list of any impaired waters within their jurisdiction as shown on the current Minnesota Pollution Control Agency (MPCA) 303d Impaired Waters. - If a Watershed Restoration and Protection Strategy (WRAPS) or TMDL study has been completed for the community, the community should include implementation strategies, including funding mechanisms that will allow the community to carry out the recommendations and requirements from the WRAPS or TMDL specific to that community. More information on the MPCA's WRAPS and TMDL programs can be found on the MPCA's web site at www.pca.state.mn.us. - Communities with designated trout streams should identify actions in their plan to address the thermal pollution effects from development. - Communities with special waters, such as outstanding resource value waters, need to meet state requirements for development near these waters 5. A local implementation program/plan that includes prioritized nonstructural, programmatic and structural solutions to priority problems identified as part of the assessment completed for number 4, above. Local official controls must be enacted within six months of the approval of the local water plan. The program/plan must: - Include areas and elevations for stormwater storage adequate to meet performance standards or official controls established in the WMO plan(s) - Define water quality protection methods adequate to meet performance standards or official controls. At a minimum, the plan should include: ■ Information on the types of best management practices to be used to improve stormwater quality and quantity. (A five-year establishment period is recommended for native plantings and bioengineering practices). ■ The maintenance schedule for the best management practices. - Clearly define the responsibilities of the community from that of the WMO(s) for carrying out the implementation components - Describe official controls and any changes to official controls. At a minimum, the plan should include: ■ An erosion and sediment control ordinance consistent with NPDES Construction Stormwater permit requirements and other applicable state requirements ■ Identify ways to control runoff rates so that land -altering activities do not increase peak stormwater flow from the site for a 24-hour precipitation event with a return frequency of 1 or 2 years. Communities with known flooding issues may want to require rate control for storms with other return frequencies (10 -year, 25 -year or 100 -year) 76
