We are excited to announce a significant infrastructure improvement project that will enhance the quality and safety of our community's road network. The project encompasses the removal and replacement of asphalt concrete and Portland cement concrete on East Via Vaquero, Pistol Creek, and Cedar Creek. Our key objectives are to enhance safety, reduce future maintenance costs, and provide a visually pleasing, smooth street surface. The project spans approximately 45,000 square feet of pavement reconstruction and rehabilitation, utilizing a total of 1,200 tons of asphalt concrete pavement and performing Portland Cement Concrete (PCC) improvements, alongside re-striping of traffic legends. The total cost amounts to $450,000.00, with $400,000.00 covered by SB-1 funds (Gas Tax) and $50,000.00 from Measure R funds, emphasizing City’s commitment to utilizing state and local resources for community benefit. We understand that construction projects may cause temporary inconvenience, but we assure you that every effort will be made to minimize disruptions and complete the work efficiently. Your cooperation and patience during the construction period are greatly appreciated as we work towards creating a safer and more aesthetically pleasing environment for all residents.
