<br />This is in response to a request for a revision to the effective Flood Insurance Study (FIS) and National
<br />Flood Insurance Program (NFIP) map for your community, Specifically, this responds to a letter dated
<br />May 26, 1995, from Mr. Brian J, Huth, P,E" Project Manager, KLH Engineering, Inc" regarding the

<br />With his letter Mr, Huth provided additional data to support a July 8, 1994, request from Mr. Dan
<br />Bunting, Regional Floodplain Administrator, Regional Building Department. Mr. Bunting requested that
<br />the Federal Emergency Management Agency (FEMA) revise the effective FIRM to show the effects of
<br />updated topographic information and the construction of a culvert at Rangewood Drive along Cottonwood
<br />Creek, from approximately 1,650 feet downstream to approximately 2,700 feet upstream of Rangewood
<br />Drive,
<br />
<br />All data required to complete our review of this request were submitted with letters dated July 8 and

<br />
<br />We have completed our review of the submitted data and the flood data shown on the effective FIRM,
<br />and have revised the FIRM to modify the elevations and floodplain and floodway boundary delineations
<br />of a flood having a I-percent chance of being equaled or exceeded in any given year (base flood) along
<br />Cottonwood Creek, from approximately 1,650 feet downstream to approximately 2,700 feet upstream of
<br />Rangewood Drive,
<br />
<br />The base flood elevations (BFEs) increased from approximately 1,650 feet upstream to 100 feet
<br />downstream of Rangewood Drive, The maximum increase in BFE, 7,1 feet, occurred just upstream of
<br />Rangewood Drive, The BFEs decreased from approximately 100 feet downstream to approximately
<br />1,650 feet downstream of Rangewood Drive, The maximum decrease in BFE, 5,2 feet, occurred
<br />approximately 250 feet downstream of Rangewood Drive, The width of the Special Flood Hazard Area
<br />(SFHA) decreased along the entire revised reach of Cottonwood Creek, The maximum decrease in SFHA
