Geotechnical Engineering Evaluation Mukiltco Boulevard Development Mukilteo, Washington I;VTRODUCTION Tl�c project sitc is located from 3606 to 3710 Mul:ilteo Boulevard, in Everett, Washingron, as shown on thc Vicinity Map in �igure I. We have been retaineti to explore the subsurface conditions at the site and prepare this report to document our findings ancl provide preliminary recommcndations for site dcvclopmcnt. Por thc purpose of completing this study, we have becn provided with an clectronic copy of a site plan prepared by C& C Surveying, dated Octobcr 30, 2000, tiNed, "Topographic Survcy for Tom Nielson/ Rex T. Strickland:' This site plan shows existing topographic information and existing stn�ctures. Wc have also been provided with a site plan prepared by Fred Qaxtcr & Associatcs dated llecembcr 12, 2002, titled, "Strickland/Nielsen Mixed Use Project." This site plan shows thc locations of the planned structures and pavements arcas, the locations of the planned detention vaidt and detention pond. Finished tloor elevations for the planned stn�ctures are also indicated. Threc residcnccs and a commercial stn�cture presenUy occupy thc site. Two of the residenccs and thc commcrcial structurc will be demolishcd. Onc of the e�isting residences within the site will be moved to the cnstern portion of thc site. Sevcn structures with associated access roads and underground utilities nre pinnned for thc sitc. Thrce of thc structures will bc nmlti-family residential, thrce of thc structures will bc mixed residential and commcrcinl space, m�d onc of thc structures will be a restaurant. Twcnty-sis residential units and 4,080 square fcet of commercial space will be constnicted. With the excuption of the singlo-story restaurant, all of tl�c structures will havc hvo storics and a basement. Thc bascmcnts arc ta have an clevation up to ten fcet below U�c surrounding grade. Retaining walls will be constructcd on thc southern side ofthe structures with bascments. A stonmvatcr detcntion vnult is planned witliin the nonlicrn portion of thc site ncar Mukiltco E3oulevard, whilc a detcntion pond is pinnncd within thc southcast corncr of the site. Mr. Prcd Baxter, the project architcct, has infomicd us that thc bottom of the dctcntion vault ��ill be approximately 12 fcet bclow csisting gradc. The detention pond will ha��c an a��crage Jeptli of l.� feet. Tlic e�isting sitc layout is shown on thc Sitc Plan in Figurc 2. Cuts up to IZ feet are planned f'or placemcnt of thc planncd structures. We anticipate that some filling ��ill bc necded for acccss road��a}� grading. Thc uzact amounts of fill wcre not known at the time this rcport �aas prcparcd.
