NATURAL WATERCOURSES <br /> <br />A natural watercourse is a channel for water movement, such as creeks, <br />streams or rivers. Through preservation of natural watercourses, and with <br />proper management, it is possible to protect the quality and supply of water, <br />plus reduce the costs associated with sewer construction and other public <br />costs. <br /> <br />Preservation of natural watercourses is an essential part of any program <br />to minimize public investment in storm sewers and improve the quality of <br />storm water runoff, however, the conservation efforts must extend beyond the <br />streams and creeks themselves, and consideration must be given to the <br />entire watershed, including wetlands, lakes, reservoirs, and ground water <br />resources. A comprehensive storm water runoff plan is the most reasonable <br />means for a community to achieve the best use of their existing water <br />resources. Champlin, Anoka, and Ramsey should initiate such a plan in all <br />watershed within their communities prior to any urban development. <br /> <br />SLOPES <br /> <br />Regulating development on hillsides has not been a major concern of the <br />northern suburbs of the Twin City area because of the availability of flat <br />land which is cheaper and easier to develop. Although the magnitude of the <br />problem is not as great as in other parts of the region or country, as people <br />seek out choice residential sites, and as land becomes more scarce, there <br />will be increasing pressure for hillside development. A separate but related <br />problem for the CAR communities is riverbank erosion (see Map 3A)'. River- <br />bank erosion is a serious problem in a few areas.
