The Honorable Bill Tedesko, Mayor

Florence, CO 81226

Dear Mayor Tedesko:

On Wednesday, June 23, 1993 I took part in a meeting regarding the ongoing study
of the Oak Creek floodplain in and around the City of Florence and the development
activity that has been taking place in that area, The purpose of this letter is to summarize
from the perspective of the Colorado Water Conservation Board what took place at the
meeting and to draw any conclusions regarding appropriate City actions,

Meeting Agenda

Dr. John Liou of FEMA's Region VIII office in Denver conducted the meeting. He
discussed the two Flood Insurance Studies (FIS') that currently cover the subject property,
one for the City of Florence and one for unincorporated Fremont County, As you may
know, FEMA retained Love and Associates of Boulder to perform a new floodplain study
for Oak Creek, After agreement had been reached last year on the hydrology (the analysis
of the flow to be used) prepared by the Albuquerque District of the V,S, Army Corps of
Engineers, Love and Associates began the job of defining flood elevations and floodplain
boundaries.

One important part of that analysis was to delineate a floodway within the floodplain.
The floodway is the most hazardous portion of the floodplain, It needs to be protected so
that floodwaters would have a corridor through which to pass even if the remainder of the
floodplain were fully developed, Development requirements are far more stringent in the
floodway than in the remaining part of the floodplain (which is known as the flood fringe),
so the delineation of the floodway is important to the community and to the affected
property owners, Because flood flows on Oak Creek would split and go in several directions
in Florence, the job of defining a floodwaywas difficult. That floodway delineation was the
major work item accomJlished by Love and Associates since the last informational meeting
was held in Florence.
