spot in the road and hence are conveyed to the north into the Keewayden Meadows
neighborhood north of U.S. 36 and west of Foothills Parkway, the same location
previously identified by the R.W. Beck study in 1973 where spills from South Boulder
Creek were reported to leave the channel and proceed north into the neighborhoods.

A discussion was held amongst the attendees as to modeling techniques, the volume of

water involved in the split flows, where the water goes once it leaves the site, etc.

Following this review meeting, Love & Associates completed their study and prepared

this report for submittal to the University of Colorado and Colorado Water Conservation

staff for their review.

ADDmONAL INFORMATION

Telephone conversations were held with Karl Mohr of the Washington, D.C. office of
FEMA on July 30, 1996. During this conversation, Mr. Mohr was asked about criteria
necessary to certify the existing Flatiron Property berm as well as the issue of re-mapping
the floodplain of the site prior to the submittal of a Letter of Map Revision (LOMR).
Mr. Mohr stated that in order to certify the berm as a flood protection levee, ll!l of
FEMA's levee criteria would have to be met. Following the completion of the required
engineering necessary for submittal of a map revision based upon FEMA's levee criteria,
a copy of this submittal document will need to be provided to both the City of Boulder
and to Boulder County. Official proof of notification of the proposed changes to the
floodplain resulting from this request to FEMA to these two affected governmental
entities will need to be documented. FEMA will review this map revision in the same
fashion they review all other map revisions assuming that all data is provided to FEMA
in the initial revision submittal. FEMA advised that the City of Boulder and Boulder
County do not need to approve the submittal, the revision requestor only is required to
provide FEMA with proof of notification to these affected entities.
