<br />profiles. CWCB staff performs technical reviews on the following types of reports and maps for
<br />approval and designation by the Board:
<br />
<br />I
<br />
<br />. "Flood Insurance Study" (FIS), which is produced by the Federal Emergency Management Agency
<br />(FEMA) and used for floodplain management, regulation, and insurance purposes.
<br />. "Flood Insurance Rate Map" (FIRM), or Digital Flood Insrurance Rate Map (DFlRM) which are
<br />produced by FEMA and used for floodplain management, regulation, and insurance purposes. A
<br />FIRM or DFIRM may be published with or without an associated hydrologic and hydraulic report.
<br />. "Flood Hazard Boundary Map" (FHBM), which was produced by the Federal Insurance
<br />Administration and are used for floodplain management, regulation, and insurance purposes. An
<br />FHBM usually depicts approximate floodplain boundaries only, and does not have an
<br />accompanying report. Note: For all FHBM designations, the CWCB staff will perform (in-house or
<br />by contract with a consultant) hydrologic analyses.
<br />. "Floodplain Information Report", which is produced by local govemments, state and federal
<br />agencies, special districts, or the private sector, and are used for floodplain management purposes
<br />and sometimes adopted by FEMA for use in Flood Insurance Rate Map revisions.
<br />. Various hydrology studies and related floodplain studies (community-wide or site specific) that
<br />depict 100--year floodplain information that is useful for floodplain management purposes.
<br />. "Floodplain Information" is a generic term used to describe any ofthe above types of reports and/or
<br />maps in the CWCB's "rules and regulations..."
<br />. "Floodplain Resolution" is a formal document prepared by CWCB staff describing the Floodplain
<br />Information that is to be designated and approved by the Board.
<br />
<br />Consent Al?:enda Item 3a
<br />Floodplain resolution number: FPR 06-590
<br />Affected communities: City and County of Denver
<br />Name of study to be formally acted on: "Flood Insurance Study, City and County of Denver, Colorado"
<br />dated November 2005 - prepared by the Federal Emergency Management Agency (FEMA).
<br />Studied streams: The report includes detailed IOO-year floodplain information for Barunum Lake,
<br />South Platte River, Clear Creek, Bear Creek, Cherry Creek, Lakewood Gulch, Lakewood Gulch
<br />Overflow, Dry Gulch (Lakewood Gulch Tributary), First Avenue Tributary, Dakota Avenue Tributary,
<br />Sand Creek, Sand Creek Overflow, Harvard Gulch, Harvard Gulch Overflow, Dry Gulch (Harvard
<br />Gulch Tributary), West Harvard Gulch, Goldsmith Gulch, Southmoor Park Tributary, Sanderson
<br />Gulch, and Weir Gulch. It includes approximate IOO-year floodplain information for Westerly Creek,
<br />Coon Creek, First Creek, First Creek Tributary, Berkeley Lake, City Park Lake, Duck Lake, Incinerator
<br />Lake, Kelly Pond, Marston Lake, Rocky Mountain Lake, Sloans Lake, Skeel Reservoir, Vaile Lake,
<br />and Windsor Lake. The studied streams are in the South Platte River watershed.
<br />Technical issues: This study includes all major waterways within the City and County of Denver and
<br />updates the maps to a Geographic Information System (GIS) platform. Due to current construction of
<br />channel improvements, flooding determined for Westerly Creek has been presented in this study as
<br />approximate. Coon Creek, First Creek, and First Creek Tributary were originally studied in detail.
<br />Due to increased development within these stream basins, Coon Creek, First Creek, and First Creek
<br />Tributary analyses have been revised to reflect fully developed basin conditions. Flooding presented
<br />for these streams has been portrayed as approximate until such time that development in these basins
<br />increases to projected conditions. A number of Letters of Map Revision were incorporated.
