Summary
Agenda Item No. ~ 0
SUBJECT:
Community Development Department
Agenda Date: May 5, 2009
Introduce an ordinance establishing aWildland-~Jrban Interface Fire Area replacing the current
Hazardous Fire Area.
RECOMMENDATION:
Staff recommends that the City Council:
• Adopt the Wildland-Urban Interface Fire: Area Ordinance indentified on attached map.
BACKGROUND:
On Apri121, 2009, the Council reviewed staff's recommendation to adopt the Wildland-Urban
Interface Fire Area map and continued the discu:;sion to get clarification on Fire Code
requirements if the new WUIFA map were to be adopted. Since then, staff has discussed the
issue with the Santa Clara County Fire Department and has provided a clarification as discussed
later in the report.
On January 30, 2007, the State of California adopted eleven new building codes covering
building, fire, plumbing, mechanical, electrical and energy regulations. Cupertino Local
jurisdictions and municipalities were required to adopt these new codes by January 1, 2008. The
new 2007 California Building Code (CBC) had ~~ new chapter, Chapter 7A, created by the
California Department of Forestry and Fire Protection (CalFire) for establishing construction
requirements for new homes ui Wildland-urban i~lterface areas. CalFire has been developing Fire
Hazard Severity Zone maps using computer modeling based on vegetation data, topography and
potential fire behavior. Calfire's original draft m~~ps consisted of Very High, High and Moderate
Fire Hazard Severity Zones but were not availab;:e at the time of code adoption. Calfire expected
to provide the recommended Fire Hazard Area maps to local Jurisdictions for adoption early in
2008, but they were unable to meet that deadline, Only the Very High Fire Hazard Severity Zone
was recommended for adoption by Calfire. The lugh and moderate fire areas were left to the local
enforcement agencies to adopt if deemed necess~~ry. California Government Code Sections
51178.5 and 51179 (a through g) require local jurisdictions to act on the Wildland-Urban
Interface Fire Area maps within 120 Days.
DISCUSSION:
CalFire's broad objective in establishing the 200'7 CBC Chapter 7A and the WUIFSZ maps was
to establish minimum standards for materials and: material assemblies to provide a reasonable
level of exterior wildfire exposure protection for new buildings constructed in a Wildland -Urban
interface fire areas. The use of ignition resistant materials and design to resist the intrusion of
flame or burning embers projected by a vegetation fire will help mitigate the losses resulting from
a repeating cycle of interface fire disasters.

Adoption of Wildland-Urban Interface Fire Area Map.

The City has been requiring fire protection standards in its local Hazardous Fire Area (Ii~A) for
about 20 years as recommended by the Santa Clara County Fire Department (SCCFD). The
original HFA map was prepared by SCCFD using a parcel by parcel site assessment to deternune
the boundary. Since the adoption of the new California Building Code (CBC) which went into
effect on January 1, 2008, staff has been requiring conformance to the new Fire Code for homes
in the HFA until the new maps were provided by CalFire.
The proposed VFHSZ map is similar to the City's existing HFA but is enhanced to designate
Very High and High Hazard areas. Even though CalFire only mandates adoption of the Very
High Hazard areas, in order to maintain the current level of protection for hillside areas in the
City, staff and the SCCFD recommend adopting an area consistent with the City's existing HFA.
Staff and the SCCFD have reviewed the boundaries of CalFire's recommended VHFHSZ map
and have made some changes to make the new WUI map consistent with the existing HFA. The
State allows local governments authority to adopt additional WUIFA if those areas are deemed at
significant risk from wildfires.
Adopting the WUIFA consistent with the City's current HFA will result in no change to Building
and Fire code requirements to homes in Cupertino. This is consistent with maps and Fire Code
requirements adopted by all adjoining local jurisdictions that are being served by the SCCFD
including Saratoga, Los Gatos, Los Altos Hills, Morgan Hill, Santa Clara County and, Monte
S ereno.
Supplemental Comments/Questions from Councilmember's
At the Apri121, 2008 meeting, Councilmember's had the following comments/questions. Staff
responses are provided in italics.
What are the differences between fire protection requirements for the HFA and the rest of
the City? Exhibit B provides a table of Fire Code requirements before and after the
adoption of the 2007 CBC for hillside areas and the rest of the City. At the time that the
2007 CBC and Chapter 7A (construction requirements for new homes in Wildland-urban
interface areas) were being considered, SCCFD had requested additional code
requirements recommended but not mandated by the State. In order to retain fire
protection policies that were in place, Cupertino and other cities served by the SCCFD
adopted these recommendations as part of the 2007 CBC and have been applying them to
their existing HFAs.
• Are there fire protection requirements in other ordinances such as the RHS (Residential
Hillside) zone or special provisions for the Oak Valley area? There are no fire protection
requirements in the Zoning Ordinance, iri special provisions for the Oak Valley area or
in other portions of the City Ordinance. These areas are in the current HFA and are
regulated by provisions in the Fire Code.
FINDING:
The City of Cupertino experiences low humidity, high winds and warm temperatures during the
summer months creating conditions which are particularly conducive to the ignition and spread of
grass, brush and structure fires. Additionally, the remoteness and steepness of some hillside areas
in the City significantly impacts the ability of emergency responders to extinguish or control
Wildland or structure fires. These factors cumulatively mandate special provisions for the

creation of defensible space around homes and ignition resistant construction in the hillside areas.
Therefore, in addition to the areas determined b:~ the State to be within the Local Very High Fire
Hazard Severity Zone of the City of Cupertino, ether areas determined by the City based on
previous recommendations from the State to be at significant risk from wildfire are included
within the Wildland-Urban Interface Fire Area. 'This is consistent with neighboring Cities that
previously had a HFA.
