Palo Alto's Architectural Review Board has given a thumbs up to plans for a seven-story housing development at El Camino Real and Curtner Avenue, so long as developers make improvements such as adding off-street parking locations and more elevators. Sares Regis Group is responsible for the application on behalf of Palo Alto developer Vittoria Management. The application calls for demolishing existing buildings along 3727-3737 and 3773-3783 El Camino Real, 378-400 Madeline Court and 388 Curtner Ave. to make room for a 183-unit, 190,132-square-foot development.
