(A) Except as provided in this chapter, those certain building codes known and designated as the California Residential Code, 2022 Edition, (Part 2.5 of Title 24), including Appendix AH Patio Covers and Appendix AQ Tiny Houses, and Appendix AZ based on the 2021 International Residential Code as published by the International Code Council, shall become the building codes of the City of Eureka for regulating the erection, construction, enlargement, alteration, repair, moving, removal, demolition, conversion, occupancy, equipment, use, height, area and maintenance of all one and two family dwellings or townhouses and structures accessory thereto in the city. The California Residential Code and its appendices shall be on file for public examination in the office of the Building Official.
(B) Amendments to the California Residential Code. The California Residential Code is hereby amended as follows:
Subsection R401.2.1 is hereby added to Chapter 4 to read as follows:
§ R401.2.1 Minimum Floor Elevation and Site Grading Requirements. The ground floor level of all buildings, building enlargements, or extensions of structures shall be at a minimum elevation of twelve and one-half feet (12.50') based on City of Eureka Datum. In addition, the site shall be graded to drain to the adjacent design finish grade of streets or alleyways.
EXCEPTIONS:
1. The provisions of this section shall not apply to general areas protected by dikes, if approved by the Director of Public Works or to areas where the existing ground elevation exceeds twelve and one-half feet (12.50') based upon city datum. This section shall not be construed to be applicable to dikes for individual properties.
2. In areas where a setback from property lines is not required and is not proposed, the ground floor level of all buildings, building enlargements or extensions of structures may be reduced upon documentation that flooding to the building and adjacent property as a result of the development will not occur as prepared by a Registered Civil Engineer and approved by the Director of Public Works. In no event, however, will the ground floor level be less than an elevation of eleven feet (11.00') based upon city datum.
3. Exceptions may be granted upon documentation of adequate measures to preclude flooding to the subject property and adjacent properties. Documentation shall be provided by a Registered Civil Engineer and approved by the Director of Public Works.
