In my professional judgment the elevations and grading of the lot/site as constructed are functionally adequate and equivalent to the specifically approved drainage plan, and will affect stormwater drainage on and off the lot/site in a manner consistent with the approved drainage plan.

Wood St. Fort Collins, CO 80522 Attention: Mr. Wes Lamarque RE: Ridgewood Hills Fourth Filing – Tract A Building #5 - Certification of Lot Grading Dear Wes, The attached Certification of Lot Grading form and Exhibit 1 document the as-built grading and drainage improvements in the immediate vicinity of Building 5 of the Ridgewood Hills Apartments south of Avondale Rd. and east of Triangle Dr. in Ridgewood Hills. During the course of construction and final grading of the portion of the site immediately adjacent to this building, it was deemed necessary to make a number of minor modifications and additions to the approved grading plan for the project to improve the efficiency of collection and conveyance of runoff immediately away from the building and into the overall drainage system for the site. Please note that none of the modifications compromised the overall concept or integrity of the approved grading plan, but the modifications did necessitate the inclusion of several “No” responses on the Certification form. Explanatory comments have been added to the form for each “No” response. I trust that the attached documentation will be acceptable, and that any SW Engineering hold that may have been placed on the issuance of a Temporary Certificate of Occupancy for Building 5 will be released. Thank you for your consideration of the attached documentation. If you have any questions or comments, please contact me immediately. Yours truly, Owen Consulting Group, Inc. Larry C.
