2. EXISTING CONDITIONS SUMMARY The site is located at 1023 100th St SW, in the City of Everett, and in Section 13, Township 28N, Range 4E, Willamette Meridian. See Figure 1 - Vicinity Map. The gross site area is approximately 0.58 acres. • Land use aroun'd`the 'site is primarily single-family homes. The existing site is developed and contains an existing house, a few sheds and parking/driveway. All of the existing impervious surfaces will be removed or replaced for this project. Vegetation on the site consists of mostly grass. The existing developable site is rectangular in shape. As previously mentioned, a geotechnical investigation was done for this project site and the general soil conditions for the-site were found to be loose to medium dense, silty-fine to medium grained sand with gravel (weathered glacial till) underlain by dense to very dense silty- fine to medium grained sand with gravel (glacial till). Explorations were done to a depth of 8 feet with no groundwater encountered, however winter high groundwater elevation is anticipated to be 5 feet below ground surface, per Cobalt Geosciences. The general site slopes for the project area are flat and average approximately 5 percent down to the southeast. Based on the existing soil information and the setbacks of the proposed improvements from any of the property lines or critical areas there is little potential for erosion or sedimentation during construction, assuming the basic.BMPs included in the SWPPP are installed and maintained properly. Refer to Figure 2 for an existing basin map. 5
