RE: Drainage Certification
East Drake Terrace P.U.D.
Project Number: 9511.00
Dear Glen:
We have completed our review of the as -built drainage and grading at the
above referenced project. This partial drainage certification is applicable to Building E
and, will be the first of several in order for our client to obtain a Certificate of
Occupancy for each building on an individual basis.
There are three (3) drainage related issues to be certified in association with
this project which 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 grading of swales surrounding the proposed
buildings,
3.) Confirmation of the discharge location of downspouts on Buildings B, C
and D,
Field survey information of as -built conditions was obtained by Landstar
Surveying, and was used to verify item 1.) above. Future verification of Item 2.) will
also be obtained from Landstar.

Partial Drainage Certification Page 2
A field inspection of the drainage appurtenances was conducted on Wednesday
February , 1 1995 by the project engineer. The following is synopsis of the
observations made during this field visit.
1) Two buildings were under construction at the time, Buildings E and B
(See attached Plan),
2) Finished grading of the site had not been completed, which is
understandable because the remaining buildings are yet to be
constructed,
3) It was observed that the downspouts on the two buildings under
construction had not been installed therefore, location of downspouts
could not be confirmed,
4) High points in the drive entrances were verified visually, confirming field
survey information,
This letter serves to certify only Item 1.) on page 1 (parking lot grades), with
Items 2.) and 3.) to be certified at a later date, upon completion of the proposed
buildings. Building E is not associated with the requirements of Items 2.) and 3.).
The following is a breakdown of the remaining work to be completed by item
number from Page 1 of this letter:

TOTAL AMOUNT IN ESCROW

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. Future certifications will gradually reduce this amount.

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.
