Aspen Engineering has made a number of site visits between December 2, 2016 and August 24, 2017 to verify the constructed condition. Aspen has reviewed the record survey prepared by King Surveyors, Inc., dated January 25, 2017 and the supplemental survey data dated March 30, 2017. Based on visual observation, Aspen asserts the site appears to be in general conformance with the approved drainage and grading plans. Please refer to the As-built Drainage Exhibit and relined copy of the As-built Drainage Exhibit for surveyed site grades and calculated slopes. Aspen is providing the following assessment of the drainage on the Poudre Valley Hospital A-Wing Replacement comprised of the north parking lot and building expansion, plaza, drive aisles and green space. 1) The finished floor elevation as constructed varies from 4972.60 to 4972.68 on the west and north sides respectively and varies from 4972.15 to 4972.28 on the east side. The design elevation is 4972.58. The finished floor elevation is 0.02 feet to 0.10 feet higher than design on the on the west and north sides respectively and approximately 0.43 feet to 0.30 feet lower than design on the east Accepted 9/26/2017 WL 12/15 Page 1 OVERALL SITE and DRAINAGE CERTIFICATION Commercial, Multi-Family and Subdivision Certification Form and Checklist Project Name: Date: Building Permit Numbers: (Commercial or multi-family) Per the requirement in Fort Collins Stormwater Criteria Manual (FCSCM) Volume 1, Section 6.11, please fill in all applicable items in this Certification Form for Commercial, Multi-Family and Overall Single Family sites.
