RE: First Interstate Bank Drive-Thru Facility - Stormwater Certification
Our Project Number: 92.13 NEE
Dear Glen:
We -have completed a field review and field survey of the stormwater improvements built as part`of
the First Interstate Bank Drive-Thru Facility. This project was completed on a 2.067 acre site at -the
southwest corner of Boardwalk Drive and the JFK Parkway.
This Follow up letter addresses three areas that we discussed to finalize this project.`'
1) The erosion control measures are installed and complete per our plans.
2) The riprap area at Pond "B" has been reshaped and is complete and drains south per_
field shots.
3) The debris and excess dirt pile have been removed. Note: there are small topsoil areas
that will be smoothed and blended along with the sprinkler installation backfill to finish
ground elevation for sodding.
As a result of our field review, I feel that the drainage improvements are in substantial conformance
with the reports and plans approved by the City of Fort Collins for this development.
Please feel free to contact me should you have additonal questions.
Sincerely,
Mike Cole

Dear Glen:
We,have completed a field review and field survey of the stormwater improvements -built -as
pa—ft-of.the First Interstate Bank Drive-Thru Facility. This project was completed on a 2.067'
acre site at the southwest corner of Boardwalk Drive and the JFK Parkway. -
As outlined in the drainage report, the, on -site drainage is conveyed via curbs to Detention_
Pond A at the center of the site. Drainage on the westerly edge of this site and from off -site-
areas around the Cables End are conveyed via curbs and drive to off -site Detention Pond B:
The outlet for Pond "A" discharges historic flows into Pond "B" and Pond "B" has been sized
for this `additional flow. I have attached copies of the field data which _was compiled during
the verification process. A summary of this information is compiled in the following table.
