Solano County Code §28.94 requires adequate off-street parking and driveway treatment to control dust on private property in unincorporated areas. Driveway encroachments onto county-maintained roads require an encroachment permit from the Solano County Department of Public Works.
Section 28.94 of the Solano County Zoning Code requires that adequate off-street parking be provided for each use and that parking areas and driveways be treated as necessary to control dust. Driveway access onto any county-maintained roadway requires a separate encroachment permit administered by the Public Works Department, which controls sight distance, drainage, and driveway width at the right-of-way line. New residential construction must demonstrate compliant driveway access to the satisfaction of Public Works and the Fire District serving the property; rural lots often must also meet California Fire Code driveway width and turnaround standards. Driveway-related improvements are otherwise reviewed at building permit, including any retaining walls over 4 feet in height (which require a building permit under Chapter 28 building safety provisions).
Constructing or modifying a driveway encroachment without an encroachment permit is a violation of the County Public Works ordinance and may result in removal of the unpermitted encroachment at the owner's expense. Parking areas that fail to control dust may be cited under Chapter 28 zoning enforcement and §28.94, with administrative citations and required remediation.
