Re: Grading Certification for 2327 Adobe Drive, Lot 17 Block 3 of the Spring Creek Farms North, Filing
No. 4 Subdivision
Dear Mr. Mogen,
The purpose of this letter is to provide the grading certification for 2327 Adobe Drive, of the Spring Creek
Farms North, Filing No. 4 Subdivision, located in Fort Collins, Colorado.
Aspen Engineering reviewed the record survey, prepared by King Surveyors, with survey measurements dated
June 27, 2017. Aspen also visited the project site on June 28, 2017 to visually observe grading within Lot 17
Block 3. Based on the provided record survey and visual observation, Aspen Engineering asserts that the
proposed grading appears to meet the intent of the approved grading and drainage plan.
Aspen is providing the following as the assessment of Lot 17 Block 3:
1) Grades along the north, south, east, and west property lines vary from approximately 1.00% to
3.92%. Grading around and adjacent to the residence appears to provide positive conveyance of
runoff away from the residence in accordance with the approved grading plan.
2) The surveyed top-of-foundation (TOF) elevation for the residence is 45.70’, versus the proposed
TOF of 45.47.
3) Aspen noted that the downspouts on the southeast, southwest, northwest, and northeast corners of
the residence (4 total) appear to be located in satisfactory areas, with runoff being conveyed away
from the residence and garage.
Based on the recorded survey elevations by King Surveyors, visual observation, and the above-mentioned
variances/ modifications from the original plans, Aspen Engineering certifies that the grading for 2327 Adobe
Drive of the Spring Creek Farms North, Filing No. 4 Subdivision, Fort Collins, Co., appears to meet the intent
of the approved grading and drainage plan, accepted by the City of Fort Collins.
