CHAPTER 3 PROTECTION OPEN SPACE 52 <br /> sewer system, measures must be taken to maintain the full capacity of watercourses to <br /> minimize flood damage to development. <br /> GOAL: FLOODPLAINS <br /> Maintain the natural capacity of floodplains to carry floodwaters. <br /> OBJECTIVES: FLOODPLAINS <br /> 1. Floodplain designations and regulations should be uniform along each watercourse. <br /> 2. Encroachments into watercourses or floodplains which would reduce their water carrying <br /> ability below planned capacity, shall not be allowed. <br /> 3. Wetlands in a floodplain should not be developed or altered. <br /> POLICY: FLOODPLAINS <br /> The City will enforce the floodplain management ordinance adopted October 4, 1978, <br /> - which is consistent with Department of Natural Resources standards and time limitations. <br /> ERODIBLE SLOPES <br /> Erodible slopes are lands whose percent of slope and surface soil type make erosion, <br /> slippage, or construction a potential hazard. Generally, these slopes have a 12 percent grade <br /> or more, although underlying soils may cause a problem at lesser grades. The moisture <br /> content of the soil also affects how the slope will erode. The Soil Conservation Service of <br /> the U.S. Department of Agriculture has determined erosion susceptibility by soil type. New <br /> Brighton has a soil survey prepared by the Soil Conservation Service which shows erodible <br /> slopes. <br /> GOAL: ERODIBLE SLOPES <br /> Preservation of erodible slopes in a natural condition can be an aesthetic addition to the <br /> City. Grading, developing and devegetating these slopes will lead to unsightly gullies and <br /> siltation of water bodies and watercourses. <br />
