Generally, surface water system maintenance in Mounds View is funded by the City's Storm Water Management Fund. The City's Storm Water Management Fund rates are reviewed annually to verify that the Fund balance is adequate to fund the surface water management implementation activities identified in the City's Capital Improvement Plan. 8.2.1 STORMWATER POND MAINTENANCE PROGRAM In addition to the City's current inspection procedures for City -maintained stormwater ponding basins, City staff has expressed interest in developing a Stormwater Pond Maintenance Program. The intent of this program is to establish specific guidelines for stormwater pond maintenance, including: ■ Design volume estimation. • Tracking sediment deposition. ■ Sediment removal triggers. ■ Sediment disposal process. 8.3 NPDES IMPLEMENTATION As discussed in Section 6.5, the City of Mounds View is designated as an NPDES Phase II MS4 community. As part of Mounds View's application to obtain permit coverage, the City's Stormwater Pollution Prevention Program (SWPPP) identifies many specific implementation items related to surface water management in Mounds View. While it is not the City's intent to reproduce the specific implementation items from their SWPPP in this LSWMP (see link to the current SWPPP in Section 6.5), the specific items identified in the SWPPP can be lumped into implementation categories, including: ■ General ongoing SWPPP implementation items, including: o system inspections. o educational materials. o website updates, etc. ■ Ordinance updates, specifically: c Construction Site and Land Disturbance Runoff Control. o Post Construction Site Runoff Control. o Illicit Discharge and Illicit Connection. • Plan review procedures and standards. ■ NPDES Annual Report. ■ Surface Water System Map. The cost for implementing the items listed above will vary from year to year, but, for budgeting purposes, estimated costs for these items are included in Table 8.3. 8.4 PRIORITY SYSTEM IMPROVEMENT PROJECTS AND ACTIVITIES Based on the assessment of the City's current surface water management program and the implementation items in the preceding sections, a list of system improvement activities has been identified. The system improvements identified range from those being driven by regulatory requirements to those driven more by the functionality of the City's regional surface water management system. Table 8.3 presents a summary of recommended surface water management activities. The budget amounts City of Mounds View 45 Local Surface Water Management Plan Stantec Project No. 193804166 (5 5tantec
