RE: -Drainage Certification
�East-Drake Terrace-P.-U-
Building F
Project Number: 9758.00
Dear Basil:
This is the fourth partial drainage certification for the above referenced project
and will include Building's C, F and G (see enclosed plan). Building D is the only
structure remaining to be certified as part of this development. The developer has
requested a separate certification letter for each building therefore, you will find three
letters contained in this submittal. Previous certifications, completed in 1995, have
already verified curb and gutter flowline elevations and high points in the parking lot.
Building F is located in the southwest corner of the site. This certification
verifies that the finished grading surrounding the building is in substantial
compliance with the approved Grading and Drainage Plans.
A field inspection of the building and finished grading was conducted on
Tuesday, September 2, 1997 by the project engineer. The following is a summary of
the observations made at the site during this field visit.
1) Building D is the only remaining structure to be constructed;
2) Building's B, E and H were all constructed and certified in 1995;
3) Landscaping surrounding Building's C, F and G is complete;
4) There are no downs pouts directed to the west on Building C.
Items to be certified in association with this project include:
1.) Verification of flowline elevations and grades in the parking areas and
location of high points in the drive entrances,
2.) Verification of finished grades surrounding the proposed buildings,
3.) Confirmation of the discharge location of down spouts on Buildings B,
C and D.

The total amount in escrow is determined by increasing the total cost
remaining, by 1.5 times, to obtain an amount to be retained in escrow by the City of
Fort Collins Stormwater Utility.
To the best of my knowledge, belief, and opinion, the drainage facilities were
constructed in accordance with the design intent of the approved drainage report and
construction drawings. If you require additional information or analysis regarding
this project please contact me at 221-4158.
