,j1111410or Resolution No. 7142 A RESOLUTION DECLARING AN EMERGENCY REGARDING THE REPAIR AND REPLACEMENT OF THE WOODS LAKE CREEK CULVERT WHEREAS, A. The City of Everett owns and operates Lake Chaplain Road, which is located in Snohomish County near the Water Filtration Plant. Lake Chaplain Road is the primary access to Water Filtration Plant, which provides potable water to the City of Everett and much of greater Snohomish County. B. Woods Lake Creek flows under Lake Chaplain Road through a 6' wide by 4' high corrugated metal pipe culvert. Increasing streamflows over the past years have caused overtopping of the road surface, which has created an unstable road prism at the stream crossing. C. Recent geotechnical investigation has revealed erosion of soil supporting the roadway embankment above the culvert, and collapse of the roadway is likely in another high streamflow event. D. As high streamflow events occur during the winter months,the culvert must be replaced during the summer of 2017. Collapse of the roadway would cut off unobstructed access to the Water Filtration Plant and would convey significant soil, pavement, and other debris into Wood's Lake Creek, detrimentally affecting the aquatic environment. E. Because of the imminent threat of roadway failure, immediate action is necessary to replace this culvert. This replacement project is roughly estimated to cost$600,000. The Public Works Department is completing plans and specifications for the project, and is in the process of securing permits and land use agreements from affected external stakeholders. The permits, agreements, plans and specifications should be ready by the end of July 2017. F. In order to finish work this summer in accordance with permit requirements (such as the fish window), construction must begin immediately in early August 2017, once plans and. specification are ready. However, the public works bid process takes at least four weeks, which would mean construction would not begin in August 2017, which it turn would mean that the project would not be completed in summer 2017. (Since the project costs about$600,000, the City cannot use its small works roster or other alternative methods of contracting, which would be the usual ways to more quickly award and execute a project.) It is the professional engineering opinion of the Public Works Department, including its Director, that not replacing the culvert in summer 2017 represents an unacceptable risk of roadway collapse.
