floodplain management. <br /> (o) To require any re-channelization of flood channels to meet or exceed the base flood <br /> elevation (100-year storm event) standard. <br /> ~p) To provide rules and practices for floodplain management and fines for violations of <br /> such rules and practices and to minimize downhill flooding and erosion from clearing of <br /> forest areas grubbing grading or re-channelization of water courses. <br /> (q) To maintain and re-establish forest areas to maintain and refill aquifers through <br /> percolation to minimize flooding and erosion through natural methods, and to protect <br /> endangered species and their habitats as part of our natural heritage as well as for their <br /> scientific significance. <br /> (r) To preserve a portion of currently vacant floodplain as open space for parks green <br /> belts floodways and habitat flyways for endangered species. <br /> <br /> Section 27-4. Scope and methods. <br /> <br /> In order to accomplish its purposes, this chapter includes methods and provisions [fer] to: <br /> (a) Restrict[ing] or prohibit[ing] uses which are dangerous to health, safety, and property due to <br /> water or erosion hazards, or which result in damaging increases in erosion or flood heights or <br /> velocities; <br /> (b) Requir[ing]e that uses vulnerable to floods, including facilities which serve such uses, be <br /> protected against flood damage at the time of initial construction; <br /> (c) Control[ling] the alteration of natural floodplains, stream channels, and natural protective <br /> barriers, which help accommodate or channel flood waters; <br /> (d) Control[ling] fill, grading, dredging, and other development which may increase flood <br /> damage; and <br /> (e) Prevent[ing] or regulate[ling] the construction of flood barriers which will unnaturally divert <br /> floodwaters or which may increase flood hazards in other areas. <br /> (f) Map watersheds and their associated watercourses including GIS maps to develop a <br /> more effective Flood Plain Management Program and mitigate the negative impacts of <br /> rainfall storm events. <br /> (g) Maintain and establish appropriate vegetative cover in high rainfall, sediment, and debris <br /> producing areas to reduce surface run-off in the watershed, decrease the risk of watercourse <br /> obstruction and ocean pollution. <br /> 3 <br /> <br />
