MND - Mitigated Negative Declaration
Present Land Use
Transportation/Primary Highway (University Drive) and Secondary Highway (Ridgeline Drive)

Document Description
The City proposes to add an additional through lane on eastbound University Drive from approx. 580 feet west of the intersection with Ridgeline Drive/Rosa Drew Lane, which would taper back to two through lanes approx. 725 feet east of the intersection. A northbound right-turn lane would be added to Ridgeline Drive from approx. 500 feet south of the intersection. The existing left turn pocket on westbound University Drive would be extended by approx. 40 feet. This project also includes new pavement, curb, gutter, sidewalk, and pedestrian ramps; modifications to the existing traffic signals to improve traffic operations; construction of low-flow shack dams, vegetated swale, and stormwater/water quality facilities. Minor permanent right-of-way acquisition would be required at the southwest and southeast corner of the project intersection.
