Policy 7: Require that the low floor elevation of new structures provide a minimum of 2 feet of freeboard above the 100-year High Water Level or 1 foot of freeboard above the emergency overflow of an adjacent pond. Policy 8: Preserve the existing water storage capacity within the 100-yr floodplain by prohibiting encroachments into the floodplain. 7.2.3 RUNOFF VOLUME Goal: Reduce pollutant loads and impacts to waterbodies and encourage groundwater recharge by reducing the volume of surface water runoff from development and redevelopment areas. Policy 9: Adopt RCWD Rule C by reference. Develop Comprehensive Stormwater Management Plans (CSMP) for required stormwater management as an alternative to meeting the requirements of RCWD Rule C, Sections 6 and 7. The RCWD is required to approve any CSMP. Review and update City code as necessary to reflect this policy. Goal: Reduce the volume of surface water runoff from existing developed areas. Policy 10: Coordinate efforts with the RCWD to minimize impervious surfaces (where feasible) when reconstructing streets and other paved surfaces to provide volume control benefit. Policy 11: Where practical, encourage the use of infiltration BMPs in existing developed areas, taking into consideration site limitations such as soil conditions, depth to groundwater, safety, snow removal, and maintenance issues. Also consider the use of stormwater reclamation for reducing stormwater runoff volume. 7.2.4 NUTRIENT AND SEDIMENT LOADING Goal: Reduce the nutrient and sediment loads discharged from land development or redevelopment. Policy 12: Adopt RCWD Rule C by reference. Develop Comprehensive Stormwater Management Plans (CSMP) for required stormwater management as an alternative to meeting the requirements of RCWD Rule C, Sections 6 and 7. The RCWD is required to approve any CSMP. Review and update City code as necessary to reflect this policy. Policy 13: Strive for the non -degradation of receiving waters in Mounds View by enforcing current surface water management standards, and in conformance with adopted RCWD Rules. Policy 14: 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. Encourage the use of the MPCA's Minimal Impact Design Standards and Minnesota Stormwater Manual (https://stormwater.pca.state.mn.us/index.php?title=Main Page) methodology for evaluating load reductions. Policy 15: Require outlet skimming up to the 1-year storm event HWL in all new surface water ponds. City of Mounds View 39 Local Surface Water Management Plan Stantec Project No. 193804166 (5 5tantec
