<br />Dear Mr, Christensen:
<br />
<br />This is in response to a request for a revision to the effective Flood Insurance Study and National Flood
<br />Insurance Program (NFIP) map for your community, Specifically, this responds to a letter dated May 17,
<br />1995, from Mr, Daniel W. Bare II, P,E., Engineer III, Town of Castle Rock, regarding the effective
<br />Flood Insurance Rate Map (FIRM) for Douglas County, Colorado. With his letter, Mr, Bare provided
<br />additional information to support his February 28, 1995, request for a Letter of Map Revision (LOMR),
<br />Mr. Bare requested that the Federal Emergency Management Agency (FEMA) revise the effective FIRM
<br />to show the effects of construction of a storm water sewer system and a detention pond along Tributary C
<br />from approximately 400 feet downstream of Interstate Highway 25 (1-25) to just downstream of the
<br />Denver and Rio Grande Western Railroad. A portion of the project area shown on the FIRM as within
<br />Douglas County, from approximately 350 feet downstream of 1.25 to just upstream of U ,S. Highway 85,
<br />has been annexed by the Town of Castle Rock,
<br />
<br />All data required to complete our review of this request were submitted with Mr, Bare's February 28 and
<br />May 17 letters and a letter dated April 17, 1995, from Ms. Vera B. Stepanek, P,E" Design Engineer,
<br />Rocky Mountain Consultants, Inc, All fees necessary to process this LOMR, a total of $2,820, have been
<br />received,
<br />
<br />We have completed our review of the submitted data and the flood data shown on the effective FIRM and
<br />have revised the FIRM to modify the floodplain boundary delineations of a flood having a l.percent
<br />chance of being equaled or exceeded in any given year (base flood) along Tributary C from approximately
<br />350 feet downstream of 1.25 to just downstream of the Denver and Rio Grande Railroad,
<br />
<br />As a result of this project, the base flood is contained in the culvert passing under U,S, Highway 85, The
<br />Special Flood Hazard Area has been removed from just upstream of U .S, Highway 85 to just downstream
<br />of the Denver and Rio Grande Western Railroad.
<br />
<br />The modifications are shown on the enclosed annotated copies of FIRM Panels 0170 C and 0186 C. This
<br />LOMR hereby revises these panels of the effective FIRM dated September 30, 1987,
<br />
