FINAL GEOLOGICAL ASSESSMENT EVERGREEN BRANCH LIBRARY & PARKING AREA EXPANSION 9512 EVERGREEN WAY EVERETT, WASHINGTON 1 INTRODUCTION 1.1 GENERAL HWA GeoSciences Inc. (HWA) has completed a geological assessment and laboratory testing program for the proposed building and parking area expansion at the Evergreen Branch Library site, located at 9512 Evergreen Way in Everett, Washington, for the Everett Department of Facilities & Property Management. The location of the site and the general configuration of the proposed building site is shown on the Vicinity Map and Site and Exploration Plan, Figures 1 and 2, respectively. The purpose of the geological assessment was to evaluate the soil and ground water conditions at the project site, and to provide recommendations for geotechnical aspects of the proposed proj ect. 1.2 PROJECT UNDERSTANDING We understand that the City of Everett proposes to expand the existing Evergreen Library building size of 8,595 square foot library by 5,860 square feet. The expansion will include extending the existing one story library structure into the lawn covered area to the west and the landscaped area to the east, as well as, expanding the south parking area by demolishing the existing duplex to the southwest property corner. Authorization to proceed was provided by Mr. Ruben Sanchez, of the Everett Department of Facilities & Property Management, on April 7th, 2017. At that time the contract had been approved by the Mayor of Everett, Mr. Ray Stephenson. Our scope of services for this project included collecting and reviewing readily available geotechnical and geological information, conducting one day of hand explorations and dynamic cone penetration (DCP) tests, performing relevant laboratory tests on selected samples, and performing engineering analyses to develop foundation bearing capacity, subsurface drainage, pavement design recommendations. Our work was accomplished in general accordance with our proposal.
