Dear Mr. Kelly:
This confirms the comments made informally by Mr. Gau - during his
14 January 1972 visit - regarding the revised proposal by The Ken R.
White Company for survey work on the Cache La Poudre flood plain.
Neither cross section overlays nor film positive enlargements are
needed by us for preparing flood plain information. Deleting these
then are satisfactory to us.
Pencilled manuscripts containing normal topographic detail for 1"=200'
mapping with 4 ft. contour intervals are satisfactory.
Cross section locations shown on the pencilled manuscripts and photo
contact prints will serve our purposes. We suggest that sections be
identified in the manner we have on the A.S.C.S, photos on which we
have delineated our requirements. We'd also like to have the stations
at the section terminals identified. It will serve our purposes if
the cross sections X and Y data are plotted directly on computer data
cards, rather than on the manuscripts. Zero horizontal position on
the data cards should represent the left end of the section looking
downstream. Duplicate copies of the punch card layout sheet and the
data card we use are inclosed. If the contractor doesn't have a sup-
ply of this type data card we will furnish to him the job's require-
ments. Also inclosed are duplicate conies of sample field notes for
stream crossings. This latter serves for the sections marked in blue
on the A.S.C.S. photos where information on culvert and bridge water-
ways and for other structures can't be picked up on the Kelsch plotter.
Photos or plans of bridge waterways - with needed dimensions added -
will serve as well as field sketches.

Mr. Edward S. Kelly
Regarding the priorities - it is our plan to complete the three volumes
of flood plain information in the order requested by the Planning
Commission. Our progress will be best if the contractor concentrates
his work in the designated order of priority. It will be helpful too
if the manuscripts and corresponding cross sections would be provided
to us, one at a time, as they are completed working from downstream
to upstream.
We're pleased that this arrangement for surveys is being concluded to
the satisfaction of all concerned. Our compliments and thanks to all
who have worked so hard to achieve the objective.
Sincerely yours,
