The property is also close to Highways I-680 and 24 and provides access to recreational facilities such as Larkey Park/Pool, Civic Park, and Shell Ridge Open Space. The three-story building features uncommon construction details that include a concrete slab foundation, low maintenance stucco exteriors, pitched tile and flat vinyl roof (replaced in February of 2026), carports, additional storage for residents, complex laundry facility, and separate meters for gas and electricity.
