So at this point it would be the county's <br />responsibility. However, if the requester submits a floodway analysis that reflects a floodway that <br />has not been optimized to the 1.0 foot maximum (i.e. maximum surcharge is 0.5 foot), then the <br />analysis will be accepted. The only thing I would point out is that there is a risk that another <br />requester could submit for a LOMR in the same area of revision and optimize the floodway to the <br />1.0 foot maximum. So the 0.5 foot floodway can be currently mapped, but it may be subject to <br />change until the area is annexed by the City of Boulder. <br /> <br />I hope this helps. Let me know if you have any questions or concerns. <br />Rick <br /> <br />From: Kevin Doyle [mailto:Kevin.Doyle@mapmodteam.com] <br />Sent: Tuesday, January 03, 2006 4:45 PM <br />To: Rick Sacbibit (FEMA) <br />Cc: Dave Jula; Anne McDaniel; bdegroot@udfcd.org; Carlson, Dan; Kevin Long (FEMA); <br />meddek@ci.boulder.co.us; nlove@loveassociates.com <br />Subject: <br /> <br />Rick, <br /> <br />I was recently asked a question about mapping a floodway for a LOMR in the City and County of <br />Boulder. I have provided some background and the question below. <br /> <br />Backqround: <br />This past spring during a monitoring visit with Kevin Long, one of the topics we discussed was <br />mapping a 0.5 foot floodway on Box Elder Creek, Cooper Slough, and Spring Creek in the City of <br />Fort Collins and surrounding Larimer County. At the time, CWCB was in the process of rewriting <br />their State Rules and Regulations in which they were planning to modify the state standards for <br />floodways. With the new rules and regulations (adopted July 14, 2005) the state remained a 1 <br />foot floodway state, but the CWCB would adopt and support more restrictive community floodway <br />criteria. <br /> <br />DEPARTMENT OF NATURAL RESOURCES COLORADO WATER CONSERVATION BOARD <br />RULES AND REGULATIONS FOR REGULATORY FLOODPLAINS IN COLORADO <br />JULY 2005 <br />Rule 7. Standards for Regulatory Floodways <br />B. Establishment of Floodway Criteria. The CWCB recognizes that designated floodways are <br />administrative limits and tools used by communities to regulate existing and future floodplain <br />developments within their jurisdictions. Communities may choose to delineate floodways based <br />on FEMA's 1-foot rise criteria or based on more strict criteria (e.g. depth and velocity criteria, 0.5 <br />foot rise, etc.). The CWCB floodway rule is synonymous with communities' adopted floodway <br />criteria. Where no local f100dway criteria exists, the CWCB recommends the use of the minimum <br />FEMA standard. <br /> <br />With the knowledge of the new CWCB rules and regulations, we decided to allow Fort Collins <br />(and other communities in Colorado) to map more restrictive floodways on the FEMA FIRMs as <br />long as the communities had already adopted the more restrictive regulations. In a follow up <br />conversation with the CWCB they mentioned that, in addition to the new rules and regulations, <br />they would also be willing to issue letters of support for the more restrictive floodways. <br /> <br />Boulder Question: <br />The City of Boulder, with the assistance of Love & Associates Inc., is preparing a LOMR for <br />Fourmile Canyon Creek from the Western Corporate boundary to Boulder Creek, and <br />Wonderland Creek from Wonderland Lake to Goose Creek. The City has asked if they could map <br /> <br />-18- <br />
