RE: Drainage Certification
East D„rakeAT_;erra -w.-P U.D.
Project Number: 9511.00
Dear Glen:
This is the second partial drainage certification at the above referenced project
and pertains to Building H only. This certification verifies the finished grading of the
swale on the south side of the building adjacent to East Drake Road.
Field survey information of as -built conditions for this certification was obtained
by Northern Engineering Services. A field inspection of the drainage swale and
associated landscaping was conducted on Wednesday May 24, 1995 by the project
engineer. The following is a synopsis of the observations made during this field visit.
1) Buildings B, E and H are all constructed with complete landscaping
surrounding Buildings E and H and Building B only rough graded,
2) It was observed that two of the downspouts on Building B discharge to
the west rather than to the south. This will need to be corrected prior to
certification of this building at a future date.
This letter serves to certify that the grades surrounding Building H are in
substantial compliance with the design intent of the Drainage and Grading Plans .

Drainage Certification
East Drake Terrace P.U.D.
Items to be certified is association with this oroiect 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.
The following is a breakdown of the remaining work to be completed:
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.
Sincerely,
NORTHERN ENGINE
