Present Land Use
The subject project involves the construction of roadway improvements for 20th Street West from Avenue P-8 to Elizabeth Lake Road and include roadway construction, construction of a bridge across the Amargosa Creek and a signal at the end of Elizabeth Lake Road. The project will not impact the adjacent zoning or General Plan designations on the adjacent properties which are all zoned R-1-7,000 with a General Plan Land Use designation of SFR 3 (Single Family; 3.1 to 6 du/ac). Residential development is occurring on adjacent parcels within the project vicinity.
Document Description
The proposed project is the southerly extension of 20th Street West from its existing southern terminus at Avenue P-8 to a new terminus at Elizabeth Lake Road at which intersection a new traffic signal will be installed. The new roadway extension will include two lanes in both directions with shoulders, curb, gutter, and sidewalk on both sides. The proposed street will widen at the intersection of Avenue P-8 to five lanes to accommodate a dedicated right turn lane. At the intersection of Elizabeth Lake Road, the new roadway extension will widen to six lanes with a raised median. The proposed six lanes at Elizabeth Lake Road include two northbound lanes and a dedicated right turn lane plus two southbound left-turn lanes and one right turn lane. In order to extend 20th Street West to Elizabeth Lake Road, a new bridge will be constructed over the Amargosa Creek. The proposed bridge is a cast-in-place pre-stressed box-girder concrete structure supported by two abutments on the ends. The bridge will carry four lanes of traffic with a shoulder and a sidewalk on each side. Pedestrian lookout areas will be provided on both sides of the bridge. The bridge will have a span of approximately 120 feet and a width of 80 feet. The vertical clearance is approximately nine feet. Concrete bicycle and pedestrian trails with a width of 16 feet will be constructed between the channel and the abutments along the creek banks. The creek channels will be hard bottom soil cement.
