SECTION II the CWCB stated that, 'The nced for dctailed flood plain managemenl information is greal since significanl commercia] growth can be anticipated: The CWCB lhen authorized preparation of the Flood Plain Management Sludy by and secured funding for thc study from SCS in September 1991. It i, anlicipated that the final F]ood Plain Management Study will be completed by October 1992. PURPOSE ASD SCOPE OF STUDY The City of Cripple Creek has experienced a significant amount of new construction, rehabilitation of existing structures and other development activity since the legalization of limited stakes gaming in November 1990. This activity is expected 10 continue as the gaming industry seeks an equilibrium with the available market for this type of industry and economic development. With this leve] of development, property values have and will continue to increase whcre it becomes more important to provide for a satisfactory ]evel of protection from the effects of natural events such as precipitation and resulting runoff. Cripple Creek has historically provided drainage facilities to prevent major damage to streets and roads. Most recently, the impact of flood plains on potentia] development and vice versa has bccome a major issue. In addition, protection of properties from runoff in area., beyond a recognized floodplain is of more concern. In Septemher 1991 the City of Cripple Creek entered into an agreement with tbc Colorado Water Cunservation Board and the U.S. Department of Agriculture Soil Conservation Service for preparation of a Flood Plain Management Study. A Plan of Work for development of the Flood Plain Management Study for the City of Cripple Creck was prepared by representatives of the Colorado Water Conservation Board (CWCB), the City of Cripple Creek, TeUer County and U.S. Department of Agriculture Soil Conservation Service (SCS). Currently, the only floud plain information availahle to local properly owners is an approximate map prepared by the Felleral Emergency Maoagement Agency (FEMA). The available flood plain information was not suitable for guiding development and prcventing structures from being built within the actual flood plain. The F]ood Plain Management Study will provide a relatively detailed flood plain identification for all drainageways within the corporate limits of tbc City of Cripple Creek. The Flood Plain Management Study will not recommend improvemenlS to drainage facilities within the flood plains nor analyze drainage facilitiesoutsille of the flood piains. Also, tbe City of Cripple Creek does not have any standardized drainage faci lity llesign guidelines for use by potentia] developers or city staff. In December 1991 the City of Cripple Creek authorized GMS, Inc. to prepare this Drainage Master Plan. The Drainage Master Plan will supplement the Flood Plain Management Study, provide the city with a planning too] for use in improving its existing storm water conveyance facilities a ndprovide detai1cd design criteria for drainagc facililies in future developments. The major objcctives of this Drainage MaSler Plan are to: \.
