structure.
5.There is a minimum grade of 5% away from the structure within the first 5 to 10 feet
adjacent to the residence.

family lots when the swale is draining the runoff from only two adjoining properties)
and are not steeper than 33% (3:1).
7.All flow lines of stormwater drainage swales are a minimum of 6 inches below the
elevation of ground adjacent to the structure and will direct drainage as shown on the
Stormwater-approved grading plan.

Re: Coester Residence (Lot 3, Bouton House Subdivision) - Certification of Lot Grading
Interwest Consulting Group was the design engineer for the Coester Residence which is located at 109 N.
Sherwood Street. The design consists of a two-story residential building.
Please accept this letter and attachments as the Certification of Lot Grading for Lot 3, Bouton House
Subdivision. The elevations for Lot 3, Bouton House Subdivision are in general conformance with the
elevations shown on the City approved Grading Plan for Coester Residence. The Certificate of Lot Grading
form is attached. The following items are checked “no” on the form and require additional explanation:
3. All elevations are within a 0.2 foot tolerance of the approved grading plan – There are several as built
elevations that exceed the 0.2 foot tolerance along the north property line but the original intent for the
drainage is in general conformance of the approved grading plan.
4. The top of foundation is at least 6 inches above the highest grade surrounding the structure - Positive
drainage is achieved away from the structure.
5. There is a minimum grade of 5% away from the structure within the first 5 to 10 feet adjacent to the
residence - Positive drainage is achieved away from the structure.
This letter is intended to supplement the Certification of Lot Grading and supports our belief that the grading
for the referenced project provides positive drainage away from structure. Therefore, we request that the lot
listed above be deemed acceptable to the City of Fort Collins.
We appreciate your time and consideration in reviewing this submittal. If you have any questions or
comments, please contact me at (970) 460-8471.
Sincerely,
Michael Oberlander, P.E.
Colorado Professional Engineer 34288
