<br />SECTIO.SIX <br /> <br />Final Two Organizational Alternatives <br /> <br />studies with input from the affected jurisdictions. The studies would be available to all <br />jurisdictions. Included in this effort would be development of a consistent set of adoption <br />guidance, Best Management Practices (BMPs), and design criteria for drainage and flood control <br />projects throughout the valley. All jurisdictions, land developers, and residents of the valley will <br />benefit from these studies. Appendix G provides recorrunendations for a drainage criteria <br />manual to be used by developers and stormwater managers throughout the Grand Valley. These <br />are preliminary recommendations that shall be updated when the Colorado Water Conservation <br />Board completes its "Statewide Drainage and Floodplain Management Criteria Manual" in 2004. <br /> <br />~ <br />l <br /> <br />\\,". ..\,.., <br />,.."" :.........~...\..,\.. <br />'~:",.":,t,.. ...... <br />~ ~.\~"~,,,, \'\ ... , ......' <br /> <br />...p'~ .~' ':~'::~:':::::~;'''~ <br /> <br />.' ::::., - <br /> <br />-,-,.. <br /> <br />~ <br />':.....

Many of <br />these washes have fences, fallen trees, <br />debris, and other things that need to be <br />kept out of the washes to prevent <br /> <br />blockage of downstream culverts and <br />bridges during floods. In other <br />communities, blocked culverts have been <br />responsible for roadway overtopping with consequences of property damage and loss of life and <br />injury during flooding.
