RE: 418 and 420 North Grant Avenue Drainage and Erosion Control Memo (01/04/22)
Addendum #1
Parcel # 9711219019
To Whom It May Concern:
The purpose of this letter is to provide an addendum to the City of Fort Collins approved drainage
and erosion control memo (01/04/22) associated with the Menning Subdivision Utility Plans by
Keefe Civil (January 2022). Approximately 2,550 square feet of existing unpaved alley required
grading improvements to effectively drain stormwater flows from the site towards Cherry Street
right-of-way.
Based on visual inspections of the alley and field survey by King Surveyors, it is my professional
opinion the completed improvements presented in the attached grading plan record drawing are in
general conformance with the City approved grading and drainage plans. In my professional
judgment, the elevations and grading of the alley are functionally adequate and will not negatively
impact downstream private properties adjacent to the alley before draining into Cherry Street
right-of-way to the south.
Please do not hesitate to reach out to me if you have any questions or comments regarding this
certification of lot grading. (970) 215-6808

RE: 418 North Grant Avenue Certification of Lot Grading
Permit Application # B2201155 and B2203216
Larimer County Parcel # 9711239020
To Whom It May Concern:
The elevations and drainage patterns shown on the attached grade exhibit by King Surveyors
(surveyed 09/13/23) are in general conformance with the city approved Menning Subdivision
Utility Plans by Keefe Civil (January 2022) with the following exception.
Item #3 in the attached certification of lot grading was initialed “No” because all as-built elevations
are not within 0.2 ft tolerance of the approved grading plan. The builder revised several concrete
and deck areas, raised the garage finished floor, and changed the drainage pattern surrounding
the garage building. Also, a small portion of the main house roof drains towards the alley. Despite
as-built elevations differing from the approved grading plans, the elevations and drainage
patterns are consistent with the site’s grading plan.
Please do not hesitate to reach out to me if you have any questions or comments regarding this
certification of lot grading. (970) 215-6808
