Adopt an ordinance entitled "AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF SANTA CLARITA, CALIFORNIA, REPEALING AND REPLACING TITLES 18 THROUGH 22, AND TITLES 24 AND 25 OF THE SANTA CLARITA MUNICIPAL CODE AND ADOPTING BY REFERENCE THE 2013 CALIFORNIA ADMINISTRATIVE, BUILDING, RESIDENTIAL, ELECTRICAL, MECHANICAL, PLUMBING, ENERGY, EXISTING BUILDING, HISTORICAL BUILDING, FIRE, GREEN BUILDING STANDARDS, AND REFERENCED STANDARDS CODES WITH CERTAIN APPENDICES AND LOCAL AMENDMENTS." BACKGROUND At the November 12, 2013, City Council meeting an ordinance was introduced and passed to second reading to adopt the 2013 California Building Standards Code (building code) along with local amendments. At the meeting, a public hearing was set, in accordance with Government Code Section 50022.3, to consider adoption of the ordinance. Public notice was duly given for the public hearing in compliance with the State of California (State) law, and a copy of the proposed codes and local amendments was made available for public view in the City Clerk's office. Adoption of this ordinance will ensure the City of Santa Clarita (City) continues to enforce the latest adopted building codes along with updated local amendments, thus providing for the safety and welfare of all citizens through the implementation of the latest technology, materials, engineering, construction, and sustainability methods, as regulated by the latest adopted building codes. The ordinance establishes an effective date of January 1, 2014, to commence enforcement of building codes and local amendments. This date conforms to the effective date established by the State for mandatory enforcement of the new codes. ALTERNATIVE ACTIONS Should City Council elect not to adopt the proposed State codes and local amendments, the City would still be required to enforce the new State codes as set forth in Health & Safety Code 17922 and 17958 et al. Additionally, the updated local amendments, if not adopted, would not be enforceable. Failure to adopt the ordinance could also result in a downgrading of the City's Insurance Services Office rating, thereby negatively affecting the insurance rates for new construction. FISCAL IMPACT This ordinance does not increase permit -related fees nor does it modify any fees charged to the public for Building & Safety provided services.

When the proposed building is within 50 feet of the most probable ground location of the trace of a known active earthquake fault shown on the aforementioned maps. In cases when a geologist has not made such a determination, the City may require the excavation of a trench, as a subsurface exploration for the purpose of determining the absence of a known active earthquake fault. Such a trench will be required if a lack of distinguishable fault features in the vicinity prevents the City from determining by a site examination, review of available aerial photographs, or by other means that the fault trace does not underlie the proposed building. The trench shall be approximately perpendicular to the most probable direction of the fault trace, at least 18 inches wide, and at least five feet in depth measured from natural grade, or to a depth satisfactory to the City. The trench must be accessible for mapping and inspection by the City, when requested, and meet the requirements of Title 8 of the California Code of Regulations, Construction Safety Orders. The trench need not extend further than the full width of the proposed structure plus five feet beyond the traversed exterior walls. A known active earthquake fault shall be presumed nonexistent if an exposure is not found in the walls or floor of the trench. The City may require a more extensive investigation by a geologist as evidence to the absence of a known active earthquake fault prior to the issuance of a building permit. EXCEPTION: The provisions of this subsection do not apply to: 1. One-story, light -frame buildings classified as R-3 and U occupancies and not exceeding 1,000 square feet in area or 12 feet in height. 2.

For the purposes of this section certain terms are defined as follows: BASE LEVEL DIAPHRAGM is the floor at, or closest to, the top of the highest level of the foundation. DIAPHRAGM ANCHORS are assemblies that connect a diaphragm to the adjacent foundation at the uphill diaphragm edge. DOWNHILL DIRECTION is the descending direction of the slope approximately perpendicular to the slope contours. FOUNDATION is concrete or masonry which supports a building, including footings, stem walls, retaining walls, and grade beams. FOUNDATION EXTENDING IN THE DOWNHILL DIRECTION is a foundation running downhill and approximately perpendicular to the uphill foundation. HILLSIDE BUILDING is any building or portion thereof constructed on or into a slope steeper than one unit vertical in three units horizontal (33.3%). If only a portion of the building is supported on or into the slope, these regulations apply to the entire building. PRIIv ARY ANCHORS are diaphragm anchors designed for and providing a direct connection as described in Sections 1613.9.5 and 1613.9.7.3 between the diaphragm and the uphill foundation. SECONDARY ANCHORS are diaphragm anchors designed for and providing a redundant 20 25 diaphragm to foundation connection, as described in Sections 1613.9.6 and 1613.9.7.4.
