Seismic Design Categories, SDC, are based on specific site locations. Values for spectral response accelerations, S1 and SS, and damped spectral response accelerations, SD1 and SDS, may be determined by entering longitude and latitude at the USGS seismic design maps application . These values, along with the risk category (most buildings in Santa Cruz County will be risk category I, II or III, with residences as Occupancy Category II), will determine the SDC. Most of Santa Cruz County will be SDC D or E. Use site soil Class D, unless a geotechnical report determines otherwise. For structures required to have a structural analysis (non-conventional), See ASCE Standard 7-10, Chapter 11, for complete Seismic Design Criteria.
Vult is 110 mph for Risk Category II buildings (most buildings). Exposure categories B (urban and suburban areas), C (open terrain with scattered obstructions or areas that are not Exposure B or D) or D (unobstructed areas and ocean front areas). For structures required to have a structural analysis (non-conventional), See ASCE Standard 7-10, Chapter 26, for complete Wind Design Criteria
Those areas mapped in a State Responsibility Area, SRA, shall comply with the Materials and Construction Methods for Exterior Wildfire Exposure in 2013 CBC, Chapter 7A for non-residential and 2013 CRC R327 for one and two family dwellings and townhomes. The county's GIS will determine if a project is in a State Responsibility Area, SRA. See WUI Codes for CBC 7A requirements, which generally mirror CRC R327 requirements.
For energy compliance, use Climate Zone 3. See the California Energy Commission's website.
