Street Surfacing, Roadway and Street Improvements

Larkstone Drive

Our firm provided high-quality, value-based civil engineering services to the City of Diamond Bar for the improvement of Larkstone Drive. These services were performed in cooperation with the City of Diamond Bar and Lewis Management Corp. The project involved roadway resurfacing, street lighting and general street improvements


Street improvements (plan, profile and specifications) included accommodating the widening of the existing street and resurfacing of the existing pavement section. A super elevation street section was utilized so that the existing curb and gutters could remain. Services also included pavement evaluation and design, project management services, design surveys and geometric analysis, construction staking and as-built surveys. This project also required coordination with other agencies and utility companies. Additionally, our team performed the necessary efforts to modify the sanitary sewer, storm drain, and street lights that were constructed and within the existing improvements and coordinated with the County of Los Angeles


Project management services included meeting attendance, assisting in the processing and acceptance of the public improvements by the County of Los Angeles, City of Diamond Bar and other utility agencies in an effort to gain final acceptance of this project. This project also required field observations with City officials to monitor construction progress.
