Plans for an affordable housing complex at Rockridge Geotechnical’s 150-170 Sierra Drive site in Walnut Creek are set to be reviewed by the Walnut Creek Planning Commission. The proposal looks to demolish the existing residential complex at the site to construct a six-story structure with 87 affordable apartments. This new building will also contain over 3,000 square feet of space for on-site services, along with surface parking for 58 cars.
