<br />, <br /> <br />- 2 - <br /> <br />Instruction #i: Criteria Manual Discrepancv Resolution <br />The policy of CWCB is to recommend that government entities in Colorado adopt the statewide . <br />Manual at their own discretion, wholly or in part, depending on the needs of the adopting agency. Each <br />entity adopting the contents of the statewide manual is responsible for enforcement of the manual <br />within its jurisdictional boundaries. <br /> <br />In the event that conflicts arise between the statewide Manual and other drainage manuals, the manual <br />adopted by the entity that has jurisdiction over the subject area will govern. <br /> <br />Instruction #2: New and Revised Floodplain Delineations <br />All new and revised floodplain delineation studies within the state of Colorado should be prepared in <br />accordance with the Colorado Water Conservation Board (CWCB) "rules and regulations for the <br />designation and approval of floodplains and of storm or floodwater runoff channels in Colorado". The <br />floodplain delineation criteria presented in the statewide manual are the technical guidelines of the <br />CWCB rules and regulations. <br /> <br />instruction #3: Rei!Ulatorv JOO-vear Floodplains <br />The IOO-year floodplains delineated by detailed or limited methods are considered to be the regulatory <br />floodplains of the storm or floodwater runoff channels in Colorado as defined in 37-60-106, Colorado <br />Revised Statues (CRS). <br /> <br />Instruction #4: Desii!'nated Floodwavs <br />The CWCB recognizes that designated floodways are administrative limits and tools used by <br />communities to regulate existing and future floodplain developments within their jurisdictions. . <br />Therefore, communities may choose to delineate floodways based on FEMA's I-foot rise criteria or <br />based on more strict criteria by allowing a lesser amount of rise above the base flood elevations. The <br />CWCB floodway policy is synonymous with communities' adopted floodway criteria. Where no local <br />floodway criteria exist, the CWCB recommends the use of the minimum FEMA standard. <br /> <br />Instruction #5: Hvdraulic Structures <br />The policy of CWCB is to recommend that the govemment entities in Colorado adopt the design <br />standards presented in the statewide Manual for hydraulic structures. The criteria presented in the <br />statewide Manual are considered to be minimum standards. However, government entities may adopt <br />higher design standards if they so desire. <br /> <br />It is recommended that design and construction of hydraulic structures that are considered for full or <br />partial funding by the CWCB be prepared in accordance with the guidelines presented in the statewide <br />Manual. The construction of new or modified hydraulic structures should not adversely impact <br />adjacent properties without due process as required by FEMA regulations and CWCB rules and <br />regulations. <br /> <br />Instruction #6: Hvdrolof!:V <br />The CWCB policy is to present hydrologic methods and models that can be used to produce reasonable <br />peak flow rates and hydrographs for use in flood-related studies and projects along drainageways <br />within the state. <br /> <br />. <br /> <br />Flood Protection.
