Regional experience
Engineering that starts with the place.
San Antonio Heights sits above Upland in a foothill setting where sloping estate lots and canyon drainage influence site layout. A driveway, pad expansion, or new building can change the way water moves through a property, making existing elevations and offsite runoff important inputs. The community’s County jurisdiction is distinct from incorporated Upland.
Calicore can develop civil site, grading, and drainage plans and coordinate the proposed work with utility information and the rest of the design team. For additions and ADUs, early layout review can clarify the available building area and the relationship to access, retaining features, and existing systems. County and serving-utility requirements are addressed according to the parcel and project scope.
