Below is a more detailed description <br />of KSN's services. <br />■ Records Research: KSN researched available San Joaquin County Final Maps, Parcel Maps, and Record of <br />Surveys within the project area to determine search locations of existing monuments of record that have <br />the potential to be impacted by the project. This included searching the San Joaquin County Web -Based <br />Records Retrieval and Viewing System for maps within the project area. An online search for Corner <br />Records was also performed, and no Corner Records were identified in the County's online system within <br />the project area. <br />• Field Surveys: KSN performed field surveys to survey the location of the proposed explorations (13 total), <br />which were marked in the field by K;einfelder. In addition, KSN used the record maps to perform a <br />Corporate Office -' , N Pershing Avenue I rtnz�;ton CA 95203 1 2099�6-0268 { www ksn}nc.coT <br />1/lest Sac{'ar emo '550 Harvor Boulevard Suite 212 1 West Sacramento CA 95691 1916-403.5900 <br />
