2008 Mounds View Comprehensive Plan ________________________________________________________________________ Chapter 5: Public Facilities 5-13 • Peak runoff rates from regulated new development, redevelopment, or site expansion projects shall not exceed existing rates for the 2-year, 10-year, and 100-year rainfall events. Rate control below existing rates may be necessary where downstream capacity issues are identified, which will require coordination with the RCWD and adjacent municipalities. • The City will require nutrient and sediment load reductions consistent with the Nationwide Urban Runoff Program (NURP) and Minnesota Pollution Control Agency guidelines in design and construction of new or modifications to existing surface water conveyance systems. Under no circumstances shall overall treatment in a new development, redevelopment, or site expansion project in any part of the City fall below 50% post- development removal for phosphorous and 80% post-development removal for total suspended solids. RCWD rules incorporate the nutrient and sediment load requirements into the Districts volume control requirement. This policy is consistent with Policy B.1 in the RCWD WMP. • The City will review the adequacy of the existing Storm Water Management Fund (City Code Section 203.07) to pay for the implementation of the projects and actions identified in Section 8. This fund will then be revised accordingly. • The City will require that erosion and sediment control practices are consistent with the standards identified in the current MPCA Construction General Permit, the Minnesota Stormwater Manual, and the RCWD WMP and current rules. This policy is consistent with BMP 4-1 in the City’s SWPPP and Policies C.4 and C.5 in the RCWD WMP. Implementation The City developed an implementation plan based on the assessment of their surface water management system (Section 6 in the LSWMP) and the direction provided by the City’s goals and policies (Section 7 in the LSWMP). A summary of the City’s implementation program is found in Table 8.3 in Section 8 of the LSWMP. This table identifies a range of implementation items from those being driven by regulatory requirements, to others driven more by the functionality of the City’s regional surface water management system. Table 8.3 presents a summary of recommended priority surface water management projects and activities. The items listed in Table 8.3 will be used as a reference for particular projects and activities specific to surface water management to be included in the capital improvement planning process. Administration The LSWMP will be incorporated into the City’s 2008 Comprehensive Plan update and will be applicable until 2018, at which time an updated plan will be required. Periodic amendments may be required to incorporate changes in local practices. In particular, changes in the Watershed Management Plan for the RCWD may require revisions to this plan. Plan amendments will be incorporated by following the review and adoption steps outlined in Section 9.1 of the LSWMP.
