Street Microsurfacing Program | city of burlingame, ca
Project scope consisted of the application of 79,716 sq. yds. of Micro-Surfacing, 21,500 feet of crack sealing, and of thermoplastic striping. Coordination of work to minimize the impacts to the public was one of the major obstacles during this project. CSG was responsible for field inspection, office engineer services, and part time resident engineer services.

Annual Resurfacing | city of east palo alto, CA
The project entailed rehabilitation of streets in including dig outs, slurry seal, micro-surfacing seal, overlay, roadway reconstruction, traffic loops and utility adjustment, striping and signing. The project consisted of implementing various preventative and rehabilitative asphalt concrete (AC) pavement maintenance measures on 18 of the worst residential streets sections in the City, focusing on arterials and collectors. The measures included approximately 84,000 sq. ft. of 4” pavement dig-out repairs, 3,400 tons of 2” asphalt concrete overlay, 32,000 sq. yds. of cape sealing with microsurfacing, crack sealing, speed bump improvements, and thermoplastic striping. The project required work prioritization to streets around an elementary school, extensive coordination with impacted residents, and coordination with SamTrans for route impacts.

Downtown Parking Lot Rehabilitation Project | city of half moon bay, ca
CSG provided construction management and inspections services for the City of Half Moon Bay Downtown Resurfacing Project 2009. This project included the grading and paving of two parking lots. One, a 5,000 sq. ft. extension of their City Hall Lot, and the other, a 12,000 sq. ft. informally used gravel lot within their downtown core.
Both lots presented the typical site engineering challenges such as drainage and SWPPP provisions, protection of adjacent buildings and fences and conformity to existing access points. An additional challenge was creation of a user-friendly parking layout to maximize the number of stalls while providing adequate landscaping and meeting current ADA regulations. The smaller, City Hall lot extension was surfaced with a 4” depth of asphalt. The fairly well compacted gravel lot required only a 2” lift of asphalt. As temporary wheel stops were installed they scraped front bumper fairings. CSG successfully acquired 4½ inch wheel stops in Arizona. |
2012 Edgewood Avenue Pavement Project | city of MILL VALLEY, ca
CSG Provided Construction management and inspection services for the City of Mill Valley Edgewood Avenue Pavement Rehabilitation Project in 2012. This half a mile project included grinding the existing AC pavement, repairing failed structural section areas and repaving using hot mix Asphalt (HMA). The work also involved installing Curb and Gutters and asphalt dikes for drainage purposes, adjusting utility boxes and manholes to grade and finally striping and installing pavement markers. Storm water Pollution prevention was observed, making sure that that temporary water pollution control practices were followed, including temporary sediment control, tracking controls and waste management.
The project presented challenges with regard to traffic control because this is a heavily travelled winding road in residential areas with only 11 foot lanes in both directions. CSG had an input in developing the traffic control plan that was used effectively during the construction of the project. CSG suggested the inclusion of flaggers to facilitate the smooth flow of traffic through the construction zone. Drainage was another item that had to be carefully constructed because properties next to the roadway were bound to be affected due to the construction during rainy season. Grades had to be carefully constructed to make sure none of the houses would be flooded in future. Conforming driveways was an added challenge which had to be done right to avoid bumps at conform points. CSG focused on public outreach by setting up a dedicated phone line for information purposes during Construction. The dedicated phone line was used to update the residents of this part of Mill Valley about what was planned and how that was going to impact their commute. |
