Vine Street Fort Collins, CO 80521 Re: Perimeter Drain & Damp -proofing Observation for 4721 Withers Drive, Fort Collins, CO Crown Engineering, Ilc. Project No. 56-01-14-05 Dear Mr. Gillen: We have visually observed the perimeter drain being installed around the exterior perimeter of the basement of the home under construction at the above referenced location. This observation was performed on May 9, 2016. The drain consists of 4" perforated drain pipe. It is placed around the basement exterior perimeters and covered with approximately 8"-10" of %" or less pea gravel. It is our opinion that the drain as installed should be an adequate means of draining out any rain, irrigation, or ground water that may filtrate down to the basement elevation of the home. The damp -proofing was observed to have been placed. It is our opinion that it was placed per generally acceptable construction practices. Thank you for consulting with us on this phase of the project. If you have any questions, please do not hesitate to contact me at (970) 691-4239.

Project No. 56-01-14-03 Dear Mr. Gillen: As requested, on April 21, 2016, we visually observed the excavation at the above referenced location. The purpose of this observation was to verify that the subsurface conditions encountered in the excavation are generally consistent with those outlined in the soils report performed by CDS Engineering Corp., Project No. 16-7900. This letter is not intended to be a summary of the soils report and does not meet the disclosure requirements of Colorado Senate Bill 13, 6-6.5-101. At the time of our observation, the excavation had been completed. The excavation revealed light brown to brown silty sands and sandy clays to the depths excavated. The subsurface conditions exposed in the excavation appeared to be generally consistent with those described in the above referenced soils report, which recommends a continuous spread footing and isolated pad type foundation system for these subsurface conditions. We also recommend that an exterior, perimeter drain be constructed for this structure. Thank you for consulting with us on this phase of the project.
