Permit Sonoma Area IDsThe map represents 42 geographic areas within the County of Sonoma. The county is divided into these areas for the purposes of various types of inspections that Permit Sonoma staff performs. These areas are named for communities but are not necessarily contiguous with any individual community boundary due to aggregation of several communities into the larger area. These areas are called Area IDs and are appended to the address attached to permits and activities processed at Permit Sonoma. Three character IDs indicate unincorporated areas and two character IDs are incorporated cities. Permit Sonoma Area IDs by Inspector Assignment Report11" x 17"

USGS Geologic Hazards - Spectral Response Acceleration CRC or CBCThe Spectral Response Acceleration CRC or CBC map represents the USGS contour intervals of spectral response acceleration expressed as a percent of gravity [%g] and influences/impacts structures built to conventional, non-engineered construction standards within specified geographical areas within Sonoma County. This map can be used to determine if a site falls within the guidelines for using the CRC (California Residential Code) rather than the more restrictive CBC (California Building Code) for conventional construction. In order to use the CRC, a site must have an SDS that is less than or equal to 1.17g which corresponds to the 175 contour interval depicted on the map. There are exceptions and design considerations that may also need to be taken into account but this is the basic guideline.11" x 17"

Where contour intervals of spectral response acceleration is less than or equal to 75 [known as SDC D], case structures residing within these geographical areas MAY use ½ inch anchor bolts. Where contour intervals of spectral response acceleration are greater than 75 [known as SDC E], case structures residing within these geographic areas are REQUIRED to use 5/8 inch anchor bolts.11" x 17"
