GeoTest Services, Inc. 4320 Thomson Avenue, Everett, WA April 12, 2019 Project No.19-0050 netting/blankets. Areas requiring permanent stabilization should be seeded with an approved grass seed mixture, hydroseeded with an approved seed - mulch -fertilizer mixture or landscaped with a suitable planting design. In addition to the preceding recommendations, typical erosion control measures during construction will be required. These measures can include a rocked construction entrance or downslope silt fencing, depending on the regulations of the City of Everett and/or the governing jurisdiction. No other mitigation are required to address erosion hazards on the property. Seismic Hazards and Liquefaction Hazard Potential Based on a review of information obtained from the Washington State Department of Natural Resources (DNR) Geologic Information Portal, the subject site is classified as having a very low liquefaction susceptibility. However, this map only provides an estimate of the likelihood that soil will liquefy as a result of an earthquake and is meant as a general guide to indicate areas potentially susceptible to liquefaction.

Red shows moderate to high susceptibility.
