SAN JOSE — A big all-affordable residential development proposed for east San Jose is pushing ahead through the city approval process and is slated to begin construction next year.

The project would add scores of affordable residences to a 1.3-acre site on Alum Rock Avenue between South Capitol Avenue and South White Road, according to a post on the San Jose Planning Department site.

An estimated 164 residences would be built as part of the development at 2880 Alum Rock Ave., the planning documents state.

Pacific West Communities, a unit of Idaho-based Pacific Cos., is the project’s developer.

“The project would involve demolition of an existing vacant 8,200 square-foot commercial restaurant and associated surface parking, the removal of on-site trees, and the construction of a six-story mixed-use building,” according to the proposal.

The 164 units would consist of 92 studio units, 58 one-bedroom units, and 14 two-bedroom units.

“The project would be a 100% affordable housing development,” the proposal stated.

About 7,500 square feet of commercial space on both the first floor and the second floor are expected to be part of the development.

Project developer Pacific West Communities is a unit of an active and veteran developer, according to the company’s website.
