The State Route 99 Manteca 6-Lane Widening Project will widen State Route 99 from four lanes to six lanes in the median between State Route 120 (City of Manteca) and Arch Road (City of Stockton), 9.5 miles. The project includes the widening of structures at Lone Tree Creek, French Camp Slough and Little Johns Creek. Interchange improvements are planned at French Camp Road and at Lathrop/Main Street. KSN was retained to provide the surveying, mapping and right-of-way engineering services for the entire project. KSN’s scope of work included coordination with Caltrans, preparation of survey control and aerial mapping, preparation of design level digital photogrammetric base mapping, design support ground surveys and existing utility research and mapping to identify utility service providers impacted by the project. KSN provided the field surveys to search and recover existing monumentation based on San Joaquin County records research and prepared the preliminary right-of-way mapping (land-net) along the project corridor. KSN provided all of the Caltrans Appraisal Mapping for the project, and prepared right of way acquisition documents which included descriptions for right of way, temporary construction easements, permanent utility easements, and resolution of necessity documents. KSN also provided all of the utility relocation construction staking service for the Lathrop/Main Street Interchange for PG&E and Verizon Facilities.
The multi-phase project falls under the Proposition 1B guidelines and is politically sensitive. KSN’s services received recognition from SJCOG as follows…“KSN fulfilled their role with the highest degree of professionalism and efficiency in performing their tasks. In doing so, the services provided were instrumental in dividing a single complex $250 million dollar project in a multi-phased project.”
