The site work has been completed and is in general conformance with the approved design. The final landscaping and clean up for the site have also been completed. Survey of the site was completed on October 13, 2020 and a site visit was conducted by Erika Schneider of Interwest Consulting Group on February 24, 2021. I have attached the stamped overall as-built survey and as-built drawings of the Storm System and Grading Plans. Also attached is the Overall Site and Drainage Certification with supporting documentation. We appreciate your time and consideration in reviewing this document. If you have any questions or need additional information, please feel free to call at any time (970) 460-8471. Sincerely, Michael Oberlander, P.E.
