California Avenue Widening

California Avenue Widening

The proposed project would widen California Avenue, between Bison Avenue and Academy Way, to convert the existing two-lane road into a four-lane road, with two lanes in each direction and a center median. A traffic signal and left-turn pockets will be installed at the intersection of California Ave./ Academy Wy., to improve the level of service. Right-turn lanes will be added within improved and/or cleared right-of-way, at the intersection of California and Bison, to improve traffic flow. A striped bicycle lane will be provided along the northbound side of the street. Signalization of the California Ave./ Theory Ave. intersection is planned as a later improvement, if traffic volumes warrant this level of traffic control. Additional stop sign controls will be added later, when warranted, at the intersection of California Ave./ Innovation. The oak tree-lined landscape zone along the eastern edge of the existing two-lane section will be retained as the center median for the four-lane roadway. Proposed grading involves excavation of roughly 21,100 cubic yards of earth material along the east side of the street. The excavated materials will be placed along the eastern side of California Ave., in an area planned for additional research and development land uses in the Health Science Complex. Additional grading would include removal/ recompaction-in-place of loose alluvial soils materials beneath the proposed fill are. Best management practices will be implemented to prevent erosion and manage site runoff properly, during and after construction. A construction lay down area is to establish along the eastern edge of California Ave., just beyond the top of the slope.
