additional input of the Mail Creek study.
3. It does not seem to be appropriate to provide a complete design of the detention pond
based on one set of criteria at substantial cost to our client and substantial time
involvement by the City of Fort Collins staff to review and comment, with a complete
redesign (with additional costs to our client and addditional staff time involvements) based
on potential changed criteria as a result of a revised study due February 11, 1994.
4. It is proposed that the preliminary submittal and approvals by the City be continued on the
current time schedule. No final approvals to occur until all drainage issues have been
addressed, designed, and approved. Our client understands that these final issues could
delay the project another month during the final process, or until the subsequent approving
cycle by the City.
Ted, we are requesting that the Preliminary Submittal be considered for approval at this time. I
believe the above request is in conformance with the discussions you, Roger Prenzlow and I had
in your office on Thursday, December 30, 1993. All issues will be addressed to the satisfaction of
the City's staff on or prior to any final approvals at the Final Subdivision Plat stage.
If I can be of service or clarify the above further, please feel free to contact me at your
convenience.
Sincerely;

due to Mr. Bouchard's concerns.
On October 28, 1993, the undersigned met with Mr. Bouchard at the project site to discuss
basically two issues: 1.) storm water drainage from Mail Creek onto his property, and 2.)
irrigation ditch laterals and personal water rights owned or operated by Mr. Bouchard. During
my conversation with Mr. Bouchard; he was adamant that no additional drainage be allowed to
enter into his property (only historic flows), he did not want an increase in size of structure to
allow additional flows (e.g. 4' x 6' reinforced concrete box culvert) to enter his property, and he
owned water rights being transported by pipe and open channel flow in Mail Creek which are not
to be altered.
These issues all occurred at the end of October, 1993, the flows in Mail Creek should have been
revisited and a final determination of final design values determined.
We are now into January, 1994 and have received the above referenced PROJECT COMMENT
SHEET stating that this project will be either delayed or stopped based on two issues:
Detailed design of either onstream or offstream detention pond prior to receipt of the final
determinations of a hydraulic study which has been recently commissioned for by the City
of Fort Collins. The results of which will not officially be available until the end of
January, 1994, or officially available for our use until approximately February 11, 1994.
Based on the comments by Stormwater Utility, the detention pond is to be designed at this
time based on values determined in a previous report.
2. Drainage improvements at the intersection of Crest and Harmony need to be included in
the study. An attachment from the current Mail Creek drainage study indicating the
requirement of a 4' x 8' reinforced concrete box culvert (this size of box culvert is different
from the one specified in the Concept Review Comments of August 23, 1993 and of my
discussion, with Mr. Schlueter on. October 15, 1993)..
Based on the above facts, we are requesting that the Preliminary Submittal phase not be delayed
pending results of a revisit of the Mail Creek hydrology/hydraulic study, currently commissioned
to be performed by RBD Engineering for the City of Fort Collins. This request is being made
based on the following:
1. The revisit to the Mail Creek drainage issue should have been initiated approximately two
months ago when the issue was recognized. Our firm would have been more than willing
to perform that study at that time and not delayed this project.
2. The issue of the onstream detention pond would have been resolved at this time with the

Preliminary Submittal Response
Storwwater Utility Comments
Fort Collins, Colorado
Dear Ted:

Colorado Springs, Colorado 80918
(719) 593-2593 • FAX (719) 528-6613
This letter is in response to the PROJECT COMMENT SHEET, prepared on December 30, 1993
by Mr. Basil Hamdan of the Stormwater Utility Department of the City of Fort Collins.
The submittal of December 6, 1993 was a preliminary submittal focusing on the conceptual
planning stages of a subdivision development and not on final detailed construction plans.
Discussions were held with Mr. Glen Schlueter of Stormwater Utility on October 15, 1993
relative to the requirements of the Mail Creek drainage basin. Two significant questions were
asked by the undersigned of Mr. Schlueter as follows:
Q. Are the 4' x 6' box culverts under Harmony Road and Crest Road manditory, or can
reduced sized structures be utilized?
A. The 4' x 6' concrete box culverts are required unless otherwise proven by additional
hydraulic study of the Mail Creek basin that reduced or increased structures are
required.
2. Q. Can onstream detention be utilized on Mail Creek immediately east of Crest Road, as
opposed to offstream?
A. Yes, onstream detention can be used if properly designed.
On October 27, 1993, the undersigned received a telephone call from Mr. Glen Schlueter at which
time Mr. Schlueter told the undersigned that he had had conversation with Mr. Joe Bouchard
(downstream property owner - immediately east of Crest Road on the Mail Creek drainage).
During this conversation with Mr. Schlueter, Glen stated that a revisit of the hydrology/hydraulics
of Mail Creek by possibly the City of Fort Collins or JR Engineering, Ltd. should be accomplished
