Measure B Group 4 Pavement Rehabilitation
Design work is near completion on the final paving project of the City's Measure B Paving Plan. Paving should occur in August to October of 2022 and will include most streets south of downtown, in Baltimore Canyon, all of Magnolia Avenue, most of Doherty Drive and South Eliseo Drive. Letters outlining the need for all street excavations to be completed prior to the work were mailed to homeowners and residents on affected streets in early December 2021. The Larkspur Municipal Code prohibits excavation of newly paved streets for five years. Anyone with planned home improvements that may trigger sewer or water service upgrades is encouraged to complete the in-street components of this work prior to the paving project.
