(Rincon) has prepared this Workplan in conjunction with our <br /> Soil Boring Permit Applications to obtain a soil boring permit for the property located at 1320 West <br /> Weber Avenue in Stockton, California (site). The s Assessor's Parcel Numbers (APNs) for the site are 145- <br /> 190-120, -130, -140, and -150. However, it is understood by Rincon that APN 154-190-150 is not <br /> accessible for this scope of work. In addition, no soil borings will be advanced on APN 145-190-140. The <br /> subject property is currently developed with two industrial buildings and associated structures used for <br /> cold storage. <br /> Rincon presents the following scope of work to advance nine borings to varying depths onsite, and <br /> collect soil, soil vapor and groundwater samples: <br /> Scope of Work <br /> Task 1 Pre-field Activities <br /> ■ Mark-outs and Underground Service Alert Notification: Rincon will conduct a site visit to perform <br /> soil boring mark-outs and notify Underground Service Alert (USA).
