Memo Section Critical Issue
Introduction Congress has approved $150 million for FY '03 floodplain mapping nationwide
I The Colorado 2002 MMIP is complete and available for review at www.cwcb.state.co.us
Z CWCB staff is ramping up for the new floodplain studies
2 CWCB staff will work with Urban Drainage & Flood Control District staff in the 7-county
Denver metro area
2 FEMA Headquarters staff has been seeking input from states and regional agencies as it
completes its FY '03 plans (note that the budget was not even adopted by Congress until
almost half of the fiscal year had passed, so FEMA's planning activities have been
corresoondinl?lv delaved for this year)
3 CWCB is conducting a pilot DFIRM project with one component in Teller County and one
component, being conducted in cooperation with the Urban Drainage & Flood Control
District, in Douglas Countv (to be comoleted at the end of June 2003)
4 CWCB has prioritized all 332 communities (cities, towns, and counties) in Colorado with
regard to mapping update needs and identified the 16 highest priority counties and 97
municipalities within those counties for potential eligibility for FY '03 activities
4 113 high priority communities (cities, towns, and counties) will have preparatory work to do
prior to developing updated mapping
4 CWCB has budgeted $500,000 for the state portion (12.5%) of the non-federal share of
mapping costs, so communities will need to come up with their local portion (12.5%) of the
cost
5 CWCB will revisit map update priorities for Colorado's 64 counties on an annual basis
6 189 Colorado communities did not fill out survey questionnaires or accompanying stream
worksheets in the summer of 2002, and they should fill those out during the summer of 2003

1 - Status of the 2002Colorado Map Modernization Implementation Plan (MMIP)
You may recall that FEMA provided a $50,000 grant to the CWCB to complete a Map
Modernization Implementation Plan (MMIP) for Colorado by September 1, 2002. This plan
identified and prioritized drainageways, streams and rivers within Colorado that may potentially
require new floodplain mapping. New floodplain maps could address floodplains that need to be re-
studied and for floodplains that have not been previously studied.

Through the workshops we conducted in June 2002, the questionnaires and community worksheets
that were filled out during July, and the hard work of our consultants, we completed the Statewide
Plan and submitted it to FEMA just before the Labor Day weekend 2002. In September 2002 the
results of that effort were presented at the annual Colorado Association of Stormwater and
Floodplain Managers (CASFM) conference in Steamboat Springs. The PowerPoint presentation
from Steamboat Springs, with a few modifications, has been posted on the CWCB website
(http://cwcb.state.co.us - then click on the "Flood Protection" button). The entire MMIP report,
with backup information, is in the process of being posted on the website as well. To date we have
not heard any objections or concerns from FEMA regarding the recommendations contained in the
MMIP, so we believe FEMA staff agrees with the findings of the plan. Those MMIP
recommendations will guide all mapping activities in Colorado during the next year. The CWCB
