Residents of the Ventura neighborhood in Palo Alto say a new affordable housing project under consideration by the city will cause parking problems and traffic congestion and are negotiating with the developer to scale it back.

Wilton Court — a 100 percent affordable housing project on the corner of Wilton Avenue and El Camino Real — could be the first project of its kind to be approved by the city since 2009. The developer is Palo Alto Housing, a nonprofit that operates throughout the Bay Area.

Palo Alto’s Architectural Review Board is reviewing the design of the project. If they approve it, the city council could vote for final approval before the year’s end.

The project would have 59 units – 58 studios and one one-bedroom — and 41 parking spaces. A quarter of the units would be reserved for adults with developmental disabilities.
