Tetra Tech. Ina. led site remediation activities to restore the site. <br /> contain the haste: and prepare for development. These actrv€tes <br /> incl~~ded initial r~radinc~ of the farmer landfill area folkowed by <br /> campactir~n of the landfill waste using a technology known as deep <br /> Dyr7atr,ic; Cr;~mpractian {C7DC}. DDC is tk;e process of carr~paating soil <br /> ~snd underlying waste by dropping a heavy v~~eight from a rig. "t"he <br /> implementation of DDC for this project is the most extensive use of <br /> this technology ir= the Soutt7ern Catifarnia region, Additional activities <br /> included construction of an engineered landfill cap of it>w linear <br /> density polyethylene ~~{ELOPE), instaltation of a landfill gas collection <br /> .and treatment system. installation of a groundwater collection anti <br /> treatment s~~sterr3, monitoring of the ground water, and installation of <br /> a building prcateetion system under each occupied building. <br /> Since begi:=3ning work early last year, Consensus tnc_ has employed <br /> a variety of techniques to convey technical information to the <br /> community and reduce anxiety surrounding site remediation <br /> activities. A prajPct manager from Consensus knc. staffs an on-sl#e <br /> ccammunity relations office and manitt~rs the project information line <br /> to address issues and questions from kocal residents and <br /> stakeholders. The project information lirye allows Consensus lnc, to <br /> tmm~;drately respond to concerns and report teem to t%e on-site <br /> teCklrllt;al tean"t. <br /> Concerns relayed through the project information line help Tetra <br /> Tech, Inc. id€:ntifiy an+~ rectify potential issues before they escalate to <br /> regulatory agencies. During the seven-month duration of DDC <br /> ac#ivities. Consensus Inc. received calls from adjacent residents <br /> voicing concerns regarding vibration Levels, Conse: <br /> seas (r'==.c_ worked <br /> collaborativel'ywlth the on-site keam and the DISC to immediately <br /> respond to resident concerns by conducting home visits and. at <br /> times, installing vibration monitorrng equipment to ensure vbratron <br /> levels ~~•ere compliant with the regulatory standards. Although <br /> vibr<~tion levels did nr~t surpass approved standards, adjustments <br /> were occasionally made in response to the community's calls to <br /> lessen the inconvenience crested by the. residual vibration levels. <br /> Consensus Ir?c, has worked closely with the DISC, the City, anti <br /> eiecisior~i-rrtakers to ensure regulatory standards and public <br /> pa~tif.;ipation requirements are met and stakeholders concerns are <br /> <br /> addressed.
