WHEREAS, California Assembly Bill 130, amending Health and Safety Code Sections
17958, 17958.5, 17958.7, and 18941.5, prohibits modifications or changes (local amendments)
that impose more restrictive standards on residential occupancies except where such local

seasonal Santa Ana winds that intensify wild fire behavior; the proximity of major fault zones that
increase the potential for seismic activity and related emergencies; and varied topography,
including steep canyons, hillsides, and an extensive wildland-urban interface area, which
complicate emergency access, evacuation, and fire suppression; and

Ordinance No. 3614
Page No. 6
The City Council of the City of Chula Vista specifically and expressly finds and declares
that each of the modifications or changes (local amendments) listed in Chula Vista Municipal
Code, 15.38, Wildland-Urban Interface Code, are reasonably necessary due to local climatic,
geological, and topographical conditions and are hereby declared to be part of this Ordinance as if
set forth fully herein. The specific local climatic, geological, and topographical findings and
justification for each of the California Wildland-Urban Interface Code amendments are as follows:
1. Local climatic conditions. Climate is one of the most significant factors influencing
fire behavior and the severity of other emergency events due to its uncontrollable nature.
During the summer and fall, Chula Vista experiences seasonal climatic conditions that pose
critical fire risks, including prolonged hot, dry weather and Santa Ana winds that frequently
contribute to fast-moving vegetation fires. Extended periods of local and statewide drought
continue to reduce vegetation fuel moisture, creating an environment where fires ignite
easily and spread rapidly under wind-driven conditions. These local conditions, combined
with the geological and topographical characteristics within the city, create hazardous
conditions for which departure from the California Building Standard Code is required.
2. Local geological conditions. Chula Vista lies within a seismically active region,
intersected by the La Nacion and Chula Vista fault zones, and is in close proximity to the
Rose Canyon fault. Earthquakes in this region can cause significant disruptions, including
damaged infrastructure, ruptured gas lines, electrical fires, and overloaded emergency
services. These hazards intensify the potential for multiple, simultaneous fire incidents and
compromise the effectiveness of private and public fire protection systems. Being that the
city is within a seismic area that includes earthquake faults, microzones, slide areas, and
local liquefaction hazards, the modifications and changes cited herein are designed to
limit property damage as a result of seismic activity.
3. Local topographical conditions. Chula Vista has several topographical features,
including bordering a bay, a lake, Otay River Valley, and Sweetwater River, parkways,
narrow streets, open space, varying elevations, bridges, overpasses, freeways, and railroad
tracks, including light rail. These conditions can impede the rapid deployment and
effectiveness of emergency resources; further, these conditions and increasing populations
can slow evacuation. Additionally, the varying elevations across the city increase wind
effect and can have significant negative impacts during vegetation and other fires. The
modifications and additions to the California Building Standards Code are reasonably
necessary to mitigate to the extent possible the respective deleterious effects and for
community health and safety.
California Health and Safety Code section 17958.7 requires that the modifications or
changes be expressly marked and identified as to which each finding refers. Therefore, the City
Council of the City of Chula Vista expressly finds that Table 1 (Expressly Marked and Identified
Findings Related to Local Amendments) below identifies the applicable City of Chula Vista
Municipal Code and California Wildland-Urban Interface Code sections, together with the
associated findings that justify modifications due to local climatic, geological, and topographical
conditions.

The California Building Standards Commission requires that all local amendments be
expressly marked to distinguish them from the original code language. Exhibit 2 (2025 California
Wildland-Urban Interface Code – Expressly Marked Amendment Matrix – City of Chula Vista
Municipal Code 15.38) provides the strike-through and underline text of the City’s proposed local
amendments, thereby fulfilling this requirement. Exhibit 2 is incorporated by reference into this
Ordinance and made a part hereof as though fully set forth herein.
B. California AB130 and Health and Safety Code 17958 Findings and Declarations
In addition to Section III A’s climatic, geological, and topographical findings, the City
Council of the City of Chula Vista specifically and expressly finds and declares that modifications
or changes (local amendments) listed in Chula Vista Municipal Code, 15.38, Wildland-Urban
Interface Code, are authorized under Health and Safety Code Section 17958(b)(3). That section,
as amended by California Assembly Bill 130, permits a city to adopt local amendments to
residential standards where such amendments are related to home hardening.
Table II (Local Amendments Authorized Under CA AB 130 and HSC 17958) below
identifies amendments that are related to home hardening. Specifically, the City’s local
amendments will require that residential and non-residential buildings constructed within the City
adopted Moderate Fire Hazard Severity Zone and within the Special Designated Vegetation
Management Area be built in accordance with the California Wildland-Urban Interface Code,
Chapter 5, Special Building Construction Regulations. These amendments are therefore expressly
authorized under CA AB 130 and Health and Safety Code 17958(b)(3).

declares that it would have adopted each section, sentence, clause, or phrase of this Ordinance,
irrespective of the fact that any one or more other sections, sentences, clauses, or phrases of the
Ordinance be declared invalid, unenforceable, or unconstitutional.
