<br />Technicallssues: This study includes all major waterways within Jefferson County and its incorporated
<br />communities and updates the maps to a Geographic Information System (GIS) platform. This restudy
<br />incorporates a number of new studied stream reaches, both detailed and approximate. In addition, a
<br />number of Letters of Map Revision were also incorporated. The Towns of Bow Mar, Lakeside, and
<br />Mountain View have no identified floodplains.
<br />Community response: This study was prepared by FEMA in cooperation with, the Urban Drainage and
<br />Flood Control District (UD&FCD), and Jefferson County and its incorporated municipalities as part of
<br />the National Map Modernization Program. One key element of the Map Modernization Program is
<br />community involvement throughout the process. Prior to publishing the new study, a final coordination
<br />meeting was held in which members of FEMA, CWCB, Jefferson County, and its incorporated
<br />muniCipalities were present. The study was fully accepted and endorsed by all agencies at this meeting.
<br />Staff fmdings: The subject Flood Insurance Study revises and therefore supersedes previous versions of
<br />the County's regulatory floodplain information. CWCB staff has determined that the subject floodplain
<br />information for Jefferson County and its incorporated communities is in conformance with the CWCB's
<br />rules and regulations for floodplain designation and approval.
<br />Staff recommendation; Staff recommends that the Board: 1) designate and approve the 100-year detailed
<br />and approximate floodplain information contained in said report for Jefferson County and incorporated
<br />municipalities, and 2) authorize staff to prepare a floodplain resolution to be signed by the Director and
<br />transmitted to Jefferson County, its incorporated municipalities, UD&FCD, and FEMA. This action is
<br />recommended in order to meet statutory requirements.
