For all street and drainage work, other than that performed by the city on city streets and drainage projects and access permits, the city requires the applicant to engage the services of a professional engineer to document and certify all inspections and testing during the construction process. It is also the responsibility of the applicant and their engineer to provide the day-to-day inspection of such work, perform such inspections and testing of materials and their placement as may be required, and to certify all such inspections and testing including compliance with the approved plans and these standards. A daily activity diary shall be kept by the applicant’s engineer or his/her designee for all days that there is street or drainage work performed on the site. Copies of all test records, inspection records and the daily diary shall be furnished to the city engineer on a weekly basis. At the time of each of the inspections as set forth in EWMC 12.56.050, the city engineer or his/her designee will visit the project site to review the work related to the required inspection. Such site visits do not relieve the applicant, the contractor or the applicant’s engineer of any responsibilities for performing all work in accordance with the approved plans and these standards. The city engineer or his/her designee may also visit the project site from time to time to monitor the overall progress of the project. (Ord. 10-09 § 9 (Exh. B), 2010)
