• Board Meeting Date: 11/18/2008
• Description: WPFM Section - Designation and Approval of 100-year Floodplain Information
• Board Meetings - Doc Type: Memo

Community response: This study was prepared by FEMA in cooperation with Montezuma
County and its incorporated municipalities as part of the National Map Modernization Program.
One key element of the Map Modernization Program is community involvement throughout the
process. Prior to publishing the new study, a final coordination meeting was held on August 21,
2007 in which members of FEMA, CWCB, Montezuma County, and the City of Cortez were
present. The study was fully accepted and endorsed by all agencies at this meeting, and any
concerns raised during the meeting have been resolved.
Staff findings: The subject Flood Insurance Study revises and therefore supersedes previous
versions of the County's regulatory floodplain information. CWCB staff has determined that the
subject floodplain information for Montezuma County and its incorporated municipalities is in
conformance with the CWCB's rules and regulations for floodplain designation and approval.
Staff recommendation: Staff recommends that the Board: 1) designate and approve the 100-year
detailed and approximate floodplain information contained in said report for Montezuma County,
the City of Cortez, the Town of Dolores, and the Town of Mancos, and 2) authorize staff to prepare
a floodplain resolution to be signed by the Director and transmitted to Montezuma County, the City
of Cortez, the Town of Dolores, and the Town of Mancos, and FEMA. This action is recommended
in order to meet statutory requirements.
Consent Agenda Item 2b
Floodplain resolution number: FPR 08-611(a-ee)
Affected communities: Varies, see attached table
Name of study to be formally acted on: Varies, see attached table
Studied streams: Varies, see attached table
Technical Issues: Each LOMR in the attached table will formally revise a portion of the
existing stated floodplain designation.
Community response: CWCB staff initiated this designation procedure. All communities were
involved in actual LOMR application and signed Community Acknowledgement Forms, which
acknowledge their involvement in the process and their approval of revised floodplain
information.
Staff findings: It was determined that because a LOMR goes through a comprehensive review
process by FEMA and its technical contractor to determine if the document meets or exceeds all
technical requirements set forth by federal regulations and CWCB Rules, it would be redundant
for CWCB staff to undergo a similar review process. For this reason, it is assumed that a LOMR
that is issued by FEMA has met all requirements for completeness and accuracy set forth by the
Rules. CWCB staff therefore endorses this study as containing the most current floodplain mapping
available and urges the affected communities to adopt said revisions to their floodplain maps for
land use regulation purposes pursuant to statutory authority.
Staff recommendation: Staff recommends that the Board: 1) designate and approve the 100-year
detailed and approximate floodplain information contained in said Letters of Map Revision and 2)
authorize staff to prepare a floodplain resolution to be signed by the Director reflecting the official
designation and approval action. This action is recommended in order to meet statutory
requirements.
