Program Vision

2.1 PROGRAM VISION

The CWCB'S Floodplain Mapping Program is the foundation of floodplain information
activities in Colorado, including FEMA mapping activities. The CWCB, in cooperation with
UDFCD for the Denver metropolitan area, will act as the coordinating and implementing agency
for the Colorado component of FEMA's nationwide Map Modernization Program, providing
accurate digital floodplain management tools and flood insurance information to as many
Colorado residents as possible. A high emphasis will be placed on areas where existing flood
hazard information needs to be updated and revised, on areas where flood hazard risk is high,
and on areas where future development is anticipated. CWCB will strive to maximize state and
local resources to complement FEMA and funding while simultaneously ensuring that floodplain
mapping is being performed in a fair and equitable manner throughout Colorado.

2.2 COLORADO'S VISION FOR PARTICIPATION IN MAP MODERNIZATION

The CWCB, in conjunction with the UDFCD for counties within the UDFCD's jurisdiction, is
coordinating Colorado's Floodplain Mapping Program in keeping with State and local goals and
in accordance with FEMA guidelines. The addition of Map Modernization activities to the
existing state program will be accomplished by implementing the following program
, management objectives:

. Assess flood mapping and other hazard needs within Colorado on a yearly basis.

. Update the Business Case Plan, the prioritization parameters, and the prioritized list of
studies on a yearly basis.

. Educate the public on the risk that flood hazards pose as well as proper floodplain
management practices and partner with municipalities to collect accurate base map and
flood hazard information.

. Perform community outreach activities, including Initial Coordination Meetings in
counties being considered for possible flood studies, and conduct Scoping Meetings that
lead to completion of flood studies and map updates based upon the yearly needs
assessment and prioritization, maximizing local ownership of these products.

. Provide new and updated digital flood hazard data to Colorado residents through the
Internet and other appropriate means, taking full advantage of local digital responses.

. Compile the digital data into a statewide base map database for use as a scoping and
assessment tool, and to facilitate flood hazard mapping activities in the future,

. Evaluate conditions and make recommendations to restudy flood hazards where
development occurs, watershed conditions change, maps become outdated, or new
information and/or methods become available.

To implement these objectives the CWCB has developed a prioritization process to select map
update candidate communities and a program for carrying out individual studies in the selected
communities. The prioritization process compares the map update needs of individual counties
throughout Colorado to one another based on both a quantitative and qualitative analysis of those
needs. For each fiscal year the process selects the most appropriate counties to be studied during
