Subdividers and developers are required to submit proposed storm drainage plans to the planning commission for approval. In the past, drainage plans have been prepared singularly or on a plat- by-plat basis. Information contained in this report will be useful in developing a master drainage plan for the study area. This report provides the outline of flood hazard areas on large scale maps specifically for this purpose. The city may provide zoning regulations ".. .to establish, regulate, restrict, and limit SUCh uses on or along any storm or floodwater runoff channel or basin, as such storm or floodwater runoff channel or basin has designated and approved by the Colorado Water Conservation Board, in order to lessen or avoid the hazards to persons and damage to property resulting fr~m the accumulation of storm or floodwaters..." as stated 1.n Sect1.on 30- 28-111 for county gover~~ents and Section 31-23-302 for municipal govorn~cnt~ of the Colorado Revi~ce Stat~tcc.
