Program Plan

It is the CWCB's intent to produce publication ready FEMA DFIRMs. Therefore, included
within the definition of DFIRM creation or conversion are tasks and costs associated with the
publication and fmalization of DFIRMs. These tasks include, but are not limited to, distribution
of preliminary FIS' and FIRMs, ensuring that 6-month compliance period requirements are met,
and preparing final deliverables (negatives for the Government Printing Office (GPO), etc.). The
CWCB does not intend to assume any of the current responsibilities of the GPO, and in fact
discourages the future production of paper mapping products in light of the recommended digital
distribution of flood hazard data for Colorado.

Additional information regarding the administrative and technical requirements and procedures
for the production of DFIRMs in Colorado, including compliance with state and FEMA
requirements, can be found in "Colorado's Map Modernization Program - Updating Colorado's
Flood Maps". More information on these tasks, including detailed definitions and cost
estimating tools, are included in Appendix D.

3.2.3 Information Technology and Database Management

Many of the information technology (IT) requirements established for flood hazard analysis and
DFIRM production are not direct requirements of the CWCR Those non-CWCB requirements
have been and will be transferred to the flood mapping engineering consultants. However, the
CWCB is interested in storing and distributing some of the final deliverables, which will result in
a need to upgrade to the current IT resources available within the Colorado DNR. The following
IT deliverables have been identified as part of the floodplain mapping program:

. Repository for fin~l DFIRM GIS deliverables. GIS data would be available for
download in the three FEMA distributed formats, Arelnfo, ArcView, and Map Info.
The basic requirements to make this service available are server space, interface
development, and maintenance costs. There is a process to expand the IT program and
to establish on-site IT staff responsible for interface development and maintenance
costs. Additionally, it is anticipated that the space requirements of the GIS data will be
within the limits of the existing server space (distribution of the three formats is
anticipated at 10-15 MB per county). Therefore, the CWCB anticipates a minor amount
of assistance for additional IT requirements to support this function.

. Repository for final DFIRM graphical deliverables. Graphical displays of the FIS and
FIRM panels would be available for download in Adobe Acrobat or similar format. The
basic requirements to make this service available are server space, interface
development, and maintenance costs. We are currently expanding the IT program to
establish on-site IT staff responsible for interface development and maintenance costs.
Server space for the distribution of this data is anticipated at 10-15 MB per FIRM panel
and 10-50 MB per FIS. The CWCB anticipates additional IT requirements to support
this function.

. Repository for back-up information used to create the DFIRM, such as hydrologic and
hydraulic data, topography, workmaps, Technical Support Data Notebook (TSDN), etc.
This information will reside on a CWCB server. The basic requirements to make this
service available are server space, interface development, and maintenance costs.
