Mary Avenue Extension Project
Fact Sheet

Project Description

The purpose of the project is to extend Mary Avenue across US 101 and SR 237 in order to improve traffic operations and circulation on the City of Sunnyvale north-south arterial roadway network and improve access to the Moffett Industrial Park.

Mary Avenue is a north-south, four to six lane City street which runs from Homestead Road to Almanor Avenue in the City of Sunnyvale. Currently, the segment of Mary Avenue north of Maude Avenue has two lanes in each direction, two way left turn lane, sidewalk and bike lanes on both sides. The proposed 0.5 mile extension project will extend Mary Avenue from Almanor Avenue northerly over US 101 and SR 237 to the Moffett Industrial Park area west of Mathilda Avenue. The roadway section proposed will be four lanes, with bike lanes and sidewalks on both sides. The project will include a 0-.25 mile span structure over US 101, SR 237 and the VTA Light Rail Station (north of SR 237). Impacts to the freeway system are anticipated to be limited to column placements in the rights of way of US 101 and SR 237. The aircraft approach zone for Moffett Field will be accounted for in the design. Preliminary concept drawings are attached.

The proposed project would be aligned so as not to conflict with other planned improvements at the US 101/SR 237 interchange. Right of way commitments have been secured for that portion of the extension north of SR 237, but additional right-of-way will be needed south of US 101 for this improvement. Some existing parking lots located north and south of US 101 and SR237 will be impacted.

Project Documentation, Funding and Schedule

This project is contained in the City of Sunnyvale General Plan and the City's Transportation Strategic Program of roadway capital improvements to support buildout of the City's General Plan.

A combined Project Study Report/Project Report (Caltrans project document) and a CEQA environmental document will be prepared for the current phase of the project. The City of Sunnyvale is the CEQA Lead Agency for this project. At the current time, no federal funds have been identified to be programmed for this project, although certain technical reports will be prepared according to NEPA requirements should later preparation of a NEPA document be required. The anticipated completion date for the CEQA Environmental Document certification and PSR/PR approval is summer, 2007. The Sunnyvale City Council will consider approval of a project alignment at that time.

Funding for preparation of the PSR/PR and CEQA documentation is from the City of Sunnyvale and the Valley Transportation Authority. A portion of funding for any subsequent project development and construction activities has been programmed by the City of Sunnyvale from transportation impact fee revenue. It is anticipated that additional outside funding from yet to be identified regional, State, or Federal sources will be required to finance project construction. A design and construction schedule has not yet been identified. The project is identified in the constrained portion of the Valley Transportation Plan 2030 Local Streets and County Roads Program.
