<br />SCOPE OF WORK <br /> <br />DR.I4Fr <br /> <br />CITY OF CANON CITY <br />FREMONT COUNTY, COLORADO <br />Floodplain Delineation Study <br />Fourmile Creek and Mud Gulch <br /> <br />August 20, 1998 <br /> <br />Agreement <br />This Scope of Work supplements a written agreement between the City of Canon City (CITY) <br />and , a professional engineering firm (herein after called "ENGINEER"). The <br />maximum CITY funding for this agreement shall not exceed $ . The Colorado Water <br />Conservation Board (CWCB) will provide technical assistance to the CITY by reviewing the <br />work of the ENGINEER. <br /> <br />Summary of Requested Work/Study Area <br />The ENGINEER shall perform field investigations, technical analyses, report writing, map <br />generating, and other tasks necessary to complete a floodplain delineation study (STUDY) of <br />lower Fourmile Creek in Canon City, Colorado. The requested STUDY will supersede portions <br />of an existing report entitled "Flood Plain Management Study, Fourmile Creek & Mud Gulch at <br />Canon City, Colorado" (Natural Resources Conservation Service, 1996). Th~: project area is <br />located in south-central Colorado within the corporate limits of Canon City in Fremont County. <br />The STUDY REACH is defined along Fourmile Creek from its confluence with the Arkansas <br />River upstream to a point approximately one-half mile north of U.S. Highway 50 (approximately <br />located at NRCS cross-section 310). The STUDY REACH includes that portion of Mud Gulch <br />downstream of U.S. Highway 50 that would potentially be affected by combined floodwaters <br />from the Fourmile Creek and Mud Gulch basins. <br /> <br />Objective <br />The objective of the STUDY is to develop detailed floodplain information for the STUDY <br />REACH. Detailed floodplain information for a portion of Fourmile Creek, including the <br />STUDY REACH, was previously developed by the Natural Resources Conservation Service <br />(NRCS). .The NRCS developed design hydrology, performed HEC-2 analyses, delineated <br />floodplains, and published a draft floodplain report for Fourmile Creek and Mud Gulch. <br />However, certain development and topographic changes in the STUDY REACH have taken <br />place since the time of the NRCS study which necessitated revised topographic mapping and will <br />require revised floodplain analyses. In addition, the CITY and the CWCB desire to evaluate and <br />revise certain hydraulic assumptions and parameters of the HEC-2 model in the most <br />downstream portion of the Fourmile Creek floodplain located South of U.S. Highway 50. <br /> <br />The preparation of the floodplain information for this STUDY will help the CITY to implement <br />floodplain zoning ordinances and/or floodplain regulations, and other land use controls, as <br />needed, to reduce potential flood damages and unwise development in the floodplain.
