Yosemite Street; Suite 100 Centennial, CO 80112 October 27, 2022 FORT COLLINS UTILITIES 700 Wood Street Fort Collins, Colorado. 80521 RE: Lot 2 Block 1 Hansen Farm, 1945 KNOBBY PINE DRIVE The purpose of this letter is to clarify conditions in the certification for 1945 KNOBBY PINE DRIVE for DR Horton. Upon grade inspection of the home, downspouts had yet to be installed. The locations for the downspouts appear clear and there are no issues inspected with the future installation of the downspouts. During our site visit, the site was clean, but as landscaping and finishing touches for the home are still in progress, final site cleanup is also still in progress. Drainage was substantially compliant with plan as all grades are within 0.2’ of plan, and drainage patterns match the grading plan of record. It is my professional opinion to approve the certification for this home. Sincerely, Hayley Young, PE B&J Surveying, Inc.
