8, The majority of the redevelopment project will occur outside the shoreline jurisdiction. Within the shoreline area, a significant percentage of the property will be preserved for open space, wetlands, and passive recreational uses. (exhibit 1, staff report; Jimerson testimony) 9. The subject property has a varied historical background. It is commonly known as the "tire fire/landfill site". Between 1917 and 1974 the site was used as a dump. For a period of time subsequent to 1974 the site was used as a recycling and storage center. In 1983 and 1984 a portion of the site was the scene of tire fires that burned for a significant amount of time. This historical activity has resulted in contaminated and unconsolidated soils being on-site. In 1985 cleanup of the site started and included a leachate collection system that isolated and removed polluted groundwater to avoid contamination of the Snohomish River. The site also contains a methane collection system that removes accumulated gases. (exhibit 1, page 2, staff report; Jimerson testimony) 10. Because the site is the location of a former landfill activity, the soils are prone to settling. It is the intent of the Applicant to structurally preload the site with excess soils to compress the existing underlying soils more rapidly than would occur with a natural process. After the predetermined length of preloading, which is estimated to be approximately nine months, the excess soils will be removed from the site and left at its final grade for development. (exhibit 1, staff report; Jimerson testimony) 11 . The project is a phased project that is to occur in two stages. The first stage is projected to begin on or around June 15, 2009, and includes the demolition of the structure on-site, the removal of some of the existing temporary erosion sedimentary control on-site, and removal of temporary stormwater management facilities that were constructed as part of phase I of the surcharge work that occurred on-site (see footnote #1). After these activities are completed the second stage of phase II is projected to start in approximately the summer of 2010. It would involve the removal of the surcharge that is to be placed on-site. The surcharge is necessary to prepare the site for future development and installation of additional temporary erosion sedimentation controls and the preparation for the temporary stormwater facilities that will remain on-site until the entire project is completed, (exhibit 2, application; Jimerson testimony) 12. Most of the area for the redevelopment project to be developed for future urban uses is located outside of the shoreline jurisdiction. A significant amount of the area within the shoreline jurisdiction is projected to be preserved for open space, wetlands, and passive recreational use. (exhibit 1, page 2, staff report) 4 / 11
