<br />Most local governments have a desire to deal with growth in a responsible and practical manner, <br />but lack the much needed floodplain planning and design criteria tools that could be used by <br />developers and their engineers. There is an obvious need for a uniform and consistent approach <br />that can be used by all of Colorado's counties and communities, <br /> <br />. <br /> <br />OBJECTIVE <br />The objective is develop a comprehensive, single volume, planning and design criteria manual that <br />will address the statewide needs and problems presented above. The manual can be made available <br />in hard copy format, digital format such as CD ROM, and it could be posted on the internet for easy <br />access by most communities, engineers, and developers. <br /> <br />CONTENT OF THE PROPOSED CRITERIA MANUAL <br />The proposed criteria manual would include the following main topics: <br /> <br />I. History of Colorado's floodplain management program <br />II. Inventory and summary of existing (local) floodplain management and storm drainage <br />criteria manuals <br />III. Summary offlood and drainage related litigation and court case decisions in Colorado <br />IV. Explanation of Colorado Drainage Law (Common Law vs. Salvage Law) <br />V. Floodfrequency design standards <br />VI. Engineering standards, criteria, policies, and regulations <br />A. Rainfall, snowmelt and hydrologic analysis methods .. <br />B. Hydraulic analysis methods <br />C. Floodplain delineation methods <br />D. Floodplain andfloodway regulations <br />E. Stormwater detention policy <br />F. Stormwater runoff policy <br />G. Erosion and sediment control <br />H. Digital mapping and GIS <br />I. Other topics (to be determined) <br />VII. References <br /> <br />STAFF RECOMMENDATION <br />The staff recommends that the Board request authorization to spend up to $125,000 of non- <br />reimbursable dollars from the CWCB Construction Fund for the development of a Statewide <br />Floodplain Management Criteria Manual. <br /> <br />1:\boardmemlnov98\26e criteria manual.doc <br /> <br />. <br /> <br />2 <br />
