City gathered a great degree of quantitative data to help study the effects of furtherance of developed areas within the community. The City will continue to use this data as a baseline for analysis as well as to consider potential outcomes of development in close proximity to wetlands Adequacy of Existing Regulatory Controls The City of Ramsey believes it has adequate policies in place to self -regulate the anticipated growth without sacrificing its abundant water resources. In addition to its ordinances, the existing greater area regulatory controls of the LRRWMO, BWSR, the Metropolitan Council, the DNR, the U.S. Army Corps of Engineers, Anoka County, etc. are more than adequate to properly manage or mitigate adverse impacts on public waters and wetlands. The City must rely on the regulatory authority of Anoka County, the LRRWMO and the regional, state, and federal plans to monitor and control the runoff entering the City from outside its jurisdiction. The City understands that it will also need to address issues brought to its attention by these outside regulating authorities. The City is also concerned that the ordinance revisions, various permit fees and charges needed to finance the proposed changes will adversely affect development in Ramsey. To ensure that Ramsey has an equal chance of attracting development, the City must rely on outside agencies and WMOs in the area to regionally enforce similar environmental requirements with comparable financing obligations. G. Adequacy of Programs The City of Ramsey believes that the BMPs promised in its City-wide SWPPP and MS4 permit are designed to adequately: 1. Limit soil erosion and water quality degradation 2. Maintain the tangible and intrinsic values of natural storage and retention systems 3. Maintain water level control structures H. Adequacy of Capital Improvement Programs The storm water improvements recommended in the City's 5-year Capital Improvement Program are designed to address and correct problems related to: 1. Runoff Quantity 2. Water Quality Management 3. Fish and Wildlife Habitat and Public Waters and Wetland Management 4. Recreational Opportunities I. Future Potential Problems The greatest potential for future problems with storm water planning is associated with the ever-growing impervious footprint that is inevitable with growth. As stated earlier, highly pervious nature of the Anoka Sand Plain means that the cumulative effect of development could result in drastically increased runoff volume and flow rates. The recommended ordinance revisions are designed to: 1. Encourage infiltration and soil ripping of newly graded sites so that developed sites can adequately mimic unimproved site runoff and flow rates. 2. Limit post development runoff rates to the existing condition so that multiple developments do not cause cumulative increases in the downstream condition. Section VI October 21, 2015 Page 51
