The project included widening the roadway to its ultimate configuration from 11th Street to just south of Annadale Avenue, and constructing an asphalt overlay from the southern widening terminus to south of North Avenue. Due to the roadway widening component, the project required acquisition of right-of-way from 14 different property owners and extensive environmental review, including the protection and impact avoidance of two properties in the project area which were determined to be eligible for listing in the National Register of Historic Places and the California Register of Historical Resources. The right-of-way acquisition component included the relocation of multiple businesses and residents and extensive coordination with the property owners. Two separate phases of site clearing and demolition construction contracts were developed and managed by Y&H, as well as the coordination of franchise utility relocations of electric, gas, and telephone facilities, prior to completing the right-of-way certification process and proceeding to project construction.
Engineering design services included the design of roadway geometrics, pavement structural section, streetlights, all new signing and striping, accessibility, drainage, landscape planting and irrigation, and the design of two reconstructed traffic signals, at Annadale Avenue and North Avenue, to provide for protected left-turn phasing where none existed prior. The traffic signal design included coordination with the existing interconnection facilities and with PG&E for overhead facility clearance at the North Avenue intersection.
Y&H was involved in the project for more than 7 years, spanning from the securing of additional Measure C funding, managing the preliminary engineering and environmental phase, coordinating and securing the additional right-of-way, performing all engineering design activities, providing bidding services, managing all construction and providing full construction inspection services.
