The new East San Diego County Assessor, Recorder and County Clerk Office (ARCC) and Archives Facility will be a valuable public resource and amenity for the City of Santee. The building combines several governmental and administrative departments that provides services from property records and tax collecting, to historical records and civil wedding ceremonies.

Mandated by the County of San Diego, the environmentally-responsible ARCC building will achieve both Net Zero Energy and LEED Gold certification. Slated to be the first Net Zero Energy archive facility in the United States, the building utilizes a 140-kW photovoltaic array that provides enough energy for the entire building with a 10 percent buffer for future growth. With such stringent sustainability and resiliency goals in mind, our design team limited the hard-wearing palette (structure as finish) and maximized daylighting (reduced lighting needs) and sun-control (reduced cooling loads).

The tightly climate-controlled archival spaces will house unique documents, including hand drawn maps, birth, marriage and death certificates, deeds and parcel maps from the 1800s, as well as a letter from President Abraham Lincoln granting land to the Mission San Luis Rey de Francia.

Using a design-build delivery method, we are partnered with C.W. Driver. The one-story building utilizes tilt-up concrete panels and open web steel joists for fast construction and column-free spaces that will house open offices, a counter for public services and the archival vault. Key features include a public street under the butterfly roof and a PV-clad shading structure in the parking lot that incentivizes fuel-efficient vehicles. Other notable features of the facility are the two on-site bioswales used for stormwater management, a critical component due to the proximity to the San Diego River and its flood plain.

Construction on the project began in October 2018, with project completion targeted for December 2019.
