PG&E Construction Begins in Downtown Mountain View

Live Poll

Do you support prioritizing housing development over temporary downtown traffic and parking access?

PG&E has initiated construction work in downtown Mountain View, resulting in traffic changes on Mercy Street. The project site, formerly a public parking lot, is slated for the development of 120 affordable apartments.

Why it matters

The Corso project aims to increase the availability of affordable housing in the city, situated directly across from Mountain View City Hall. This development requires significant site preparation and utility work, necessitating temporary traffic adjustments for local commuters.

The construction project encompasses a 1.5-acre site formerly known as Lot 12. Plans call for the completion of 120 affordable apartments.

The players

PG&E

This is a major California utility provider responsible for managing the initial construction and infrastructure work on the site.

Mountain View City Hall

The local municipal headquarters serves as the primary landmark adjacent to the new housing development site.

The details

Construction is active on Mercy Street between Bryant Street and Shoreline Boulevard, forcing the road to operate as a one-way street. Drivers are currently managed by flaggers and signage, while parking alternatives remain available at the nearby City Hall and library garages.

Construction and associated road closures began on October 19, 2026.
Road closures and construction work are scheduled to end on November 20, 2026.
The 120 affordable apartments are expected to open in early 2028.

Market Landscape

The conversion of this public parking space into high-density residential housing reflects a broader urban planning shift toward utilizing under-developed city land to solve housing shortages. This development positions the city to meet aggressive affordable housing targets despite potential short-term infrastructure strain.

Commuters should anticipate delays on Mercy Street until late November 2026 while construction is underway. Those seeking parking can utilize the facilities at the City Hall or the Mountain View Public Library parking garages.

The takeaway

Residents should plan for longer commute times through the downtown area for the next month due to the one-way traffic configuration. Long-term, the city expects this site to provide significant relief through the addition of 120 new affordable housing units by 2028.
