FEMA offers training grant to CWCR: The region Vill office of the Federal
Emergency Management Agency recently offered a training grant to the CWCB in
support of Floodplain Map Modernization activities in Colorado and nearby states within
the region. The CWCB is well positioned to assist FEMA in meeting the goal of
updating floodplain maps using the state-of-the art methodologies and guidelines.
Through the subject grant, the CWCB will assist FEMA Region Vill with a training
workshop/seminar that is intended to cover such issues as technical and administrative
issues related to map production, map maintenance, electronic accessibility, the new
Mapping Portal, and other such topics pertinent to Map Modernization. The 100%
federal grant (cash match not required) is in the amount of$27,817. FEMA and the
CWCB propose to contract the assistance of consulting engineering expertise to develop
and host a multi-day training workshop/seminar. The proposed timeframe for the
training will be spring of 2005, and the proposed location is within the Denver
Metropolitan Area. The audience will be FEMA and State specialists along with Map
Mod contractors and other flood hazard mapping partners.

--- -- Hydrology study proposed for'Little-Thompson River: The -Little Thompso'n River' .- - - . -
watershed has its headwaters in Larimer County and contains drainage areas within
Boulder and Weld Counties. The need for a detailed hydrologic analysis of that
watershed has been brought to the CWCB staffs attention by several important factors.
First, there is significant growth and development occurring in the lower basin in both .
Larimer and Weld Counties. The communities of Berthoud, Milliken, and Johnstown are
all experiencing unprecedented development pressure and are annexing lands within or
near the floodplain of the Little Thompson River. Current floodplain mapping consists
mainly of outdated approximate Zone A floodplain information that is not sufficient for
today's needs. In addition, a countywide Digital Flood Insurance Rate Map (DFlRM)
study is now being conducted by the CWCB, its Consultant, and other mapping partners
for Larimer County. It is the desire of all mapping stakeholders to produce detailed
accurate floodplain information for the Little Thompson River that can be published as
part of the new DFIRM product for the County. The CWCB has taken the technical and
contracting lead for the hydrologic study, which will be paid for mainly through funds
made available from private development interests in the basin. A qualified consulting
engineer will be contracted to perform the necessary tasks of the study, and a committee
will review and evaluate the scope of work, interim products, and the draft report for
potential inclusion in the new DFIRM for Larimer County.

Cherry Creek PMP Study: On February 18, 2004, CWCB Director, Rod Kuharich sent
a letter and Final Copies of the report for the project entitled "Technical Review for the
Probable Maximum Precipitation (pMP) Site-Specific Study for Cherry Creek Reservoir"
to the US Army Corps of Engineers, District Engineer, Colonel Ubbelohhde. The CWCB
was charged with conducting an independent review of the 1995 National Weather
Service PMP Study through SB 99-023. On August 10, 2004 the CWCB received a
response from the U.S. Army Corps of Engineers, new District Engineer, Colonel Jeffrey .
