Bottom line of debate at the end of the meeting:
IS PALMER DIVIDE/OROGRAPHIC CONSIDERATIONS POSING A SIGNIFICANT BARRIER TIIAT
REQUIRES ADJUSTMENT?

Should Congressional language be proposed to the House Committee Report for the Corps FY 04-05
operations and maintenance budget? Suggested language should read:

"Except limited funding may be used to take necessary actions including considerations of
the State of Colorado PMP Technical Review and continue coordination with the Cherry
creek Advisory Committee to bring to resolution the appropriate values for the Probable
Maximum Precipitation and Probable Maximum Flood and related studies for the Cherry
Creek Dam and Reservoir in Colorado."

Project Study Schedule:
?? Pre-Final Project Meeting was April 2, 2003 which included the A W A report and
presentation of findings.

?? Technical Review Panel and Advisory Committee comments are due by May 16, 2003.
These comments should include the National Weather Service. All comments will be an
appendix in the final report and addressed to the extent possible.

?? CWCB will facilitate project vision meetings with the project sponsors ~ Arapaho County,
Douglas County, City of Aurora, and City of Greenwood Village.

?? The local sponsors with assistance from the state will need to provide Congressional
testimony in Washington D.C. regarding the future funding for the Corps of Engineers to
address issues around Cherry Creek Reservoir.
