Updated Surface Water Management Plan (SWMP) <br />City of Ramsey, Minnesota <br />2. The recommended corrections for flood prone areas will be made as described <br />herein and made a part of the storm water management system, where feasible. <br />3. Standard review procedures will be established, where feasible, to ensure all <br />development within the City is in compliance with proper erosion control <br />practices. <br />4. Detailed hydrologic analysis will be required, where feasible, during final design <br />of all new developments and ponding areas. <br />5. Final high water levels governing building elevations adjacent to ponding areas <br />and floodplains will be established as development occurs or when drainage <br />facilities are constructed. <br />6. Overflow routes will be established and maintained, where feasible, to provide <br />relief during extreme storm conditions, which exceed design conditions. <br />7. An emergency overflow should be constructed for Lake Itasca to relieve the <br />extreme fluctuation in lake levels of this isolated lake. <br />8. A storm water maintenance program will be enforced, where feasible, to ensure <br />the successful operation of the drainage system. <br />9. The erosion and sedimentation control criteria for new developments will be <br />enforced, where feasible. <br />10. An education program for City residents, staff, and development community will <br />be implemented, where feasible. <br />11. Amendments to the plan will be adopted and implemented as warranted by future <br />standards or regulations, where feasible. <br />12. That the plan should be updated in the year 2022 or earlier if needed and feasible. <br />The existing storm sewer system of the City of Ramsey is not adequate to handle the <br />continued development around the presently developed area. If development continues, <br />the existing system will need major improvement and enlargements to effectively serve <br />the community without excessive flooding. The proposed infiltration and oversized <br />ponding development scenario together with strategically located regional ponds presents <br />one method of accommodating the present growth of Ramsey. However, this report and <br />the proposed scenario is not necessarily the only method of accomplishing the goal of <br />comprehensive storm water management. <br />Given this, it is imperative that this plan and the SSA model of the City is continually <br />updated on a regular basis and compared to the baseline runoff of the existing conditions <br />model to ensure that any adjustments in area developments continue to be coordinated. <br />In addition, the proposed storm water development charges should be updated annually to <br />ensure that the associated City costs are fully financed. In this manner, the plan can <br />maintain its usefulness as a current document. <br />Finally, the EPA has initiated the NPDES Phase II requirements whereby cities with <br />populations in excess of 10,000 people are required to apply for a Phase II permit. Some <br />additional cities that are actually under 10,000 in population are also included. The City <br />of Ramsey is a mandatory small MS4 community. One of the requirements of the <br />NPDES permitting process is the existence of a storm water management plan. <br />Section X <br />October 21, 2015 Page 72 <br />
