I � pavement section consisting of a minimum thiclmess of 3 inches of AC (asphalt concrete) over ( at least 6 inchea of crushad rock base coucse should be adequate for access roada and in I man�vering and pazking ueas subjeded W the indicated u�affic loads. If pazlting aras ue limited to passenger wcomobile traffic only, the pavement sedion can be raduced to a minimum ( of 2 inches of AC over a minimum of 4 inches of cnuhed rock base course. 'Ihe asphalt ooncrete pavement and aggregate base atwnld conform to applicable � requirements of WSDOT (Washington State Depaztment of Transpo�tadon) Standard Specifications for Road, Bridge and Municipal Conshuction. Aggregate base should be p�aced � in one lift and compacted to not le�s than 95 perrP,nt of the maximum dry deosity u detamined by ASTM D-1557. '!he asphalt ooncrece is to be compacted to a minimum of 92 perceat of maximum density as determined by WSDOT Test Method 705. 1 PHASE I ENVIRONMENTAL CONCERNS t We did not idendfy any eacisting or potential sources of contamination presently on the aite, � based on our research and site reconnaissance. Also, our research did not indicate any evidence of pazt development on the subject site or adjacent properties. Some industriat facilities, ( including 'Ihe Boeing Company and John Fluke Manufacturing Company, are located approximately 1/2 mile south of the subjed site. However, our research did not indicate any � potendal impads to the subject site associated with hazardous materials that msy exist at these locations. Based on the results of our Phaee I ESA, we conclude that the risk of environmeatal liabilities associatad with ownership of the site is low. t LIMITATIONS { GEOTECHNICAL ENGINEERING SERVICES � We have prepazed this report for use b Cintas Co y cporation and members of the design team in design of a portion of this project, 'Ihe report is not intended for use by others and the I, information contained herein is not applicable to other sites.
