Barrera N : R10306IDFAWWIN DATE: April 28, 1998 SUBJECT: ESTABLISHMENT OF FIRE HAZARD ZONES AND CONSTRUCTION REQUIREMENTS FOR PROJECTS IN FIRE HAZARD ZONES DEPARTMENT: Planning and Building Services That the City Council conducts the first reading of Ordinance No. 98-5 and schedules a second reading for the next Council meeting. BACKGROUND This item is in response to State Assembly Bill AB337 (Bates) which requires that local jurisdictions identify and designate areas of severe fire hazard. The Bill refers to these areas as "Very High Fire Hazard Severity Zones." It also requires that the jurisdiction adopt construction requirements that will reduce fire risk for buildings and structures constructed in these zones. City staff has met with the Los Angeles County Fire Department to establish these zones within the City and to develop construction standards that would reasonably reduce. fire risk. The Fire Department conducted a field survey of the City in February to assess the topography, dwelling density and vegetative fuel density. The weather and climate of the Santa Clarita Valley were also considered as well as additional data from previous field surveys and fire spread computer modeling. The Very High Fire Hazard Severity Zone was identified as the area within 1,000 feet of a natural brush area. These areas have been plotted on a City map, which will be used for reference during the permit review process for enforcement of applicable construction regulations. p, p d `` Agenda r ESTABLISHMENT OF FIRE HAZARD ZONES AND CONSTRUCTION REQUIREMENTS FOR PROJECTS IN FIRE HAZARD ZONES April 28, 1998 The proposed ordinance establishes the Fire Hazard Zone by definition in lieu of an official map to facilitate enforcement. The Fire Hazard Zone is defined as any area within 1,000 feet of a natural brush area. The ordinance also sets the following construction regulations to reduce the fire hazard to buildings in this zone: 1. Requiring Class "A" roofs. This is the most fire resistant rating for any roofing material. 2. Requiring spark arrestors for chimneys. 3. Requiring exterior walls to be constructed of non-combustible finish materials such as stucco. 4. Requiring exterior doors to be solid core construction. 5. Requiring screens over attic vents to reduce embers from entering unused areas of buildings. 6. Requiring unused underfloor areas to be enclosed to prevent embers from flying into these combustible areas. 7. That decks and patio covers are constructed of not less than 2x framing members. 8. Requiring signage in front of properties having pools to identify them as emergency sources of water when fighting brush fires. These requirements are not retroactive. The provisions of the proposed ordinance were presented to the Building Industry Association as well as local contractors, developers and designers for comment. No significant opposition was expressed during the public participation process. Those provisions the Fire Department recommended but which were found to be difficult to enforce have been omitted from the Ordinance. ALTERNATIVE ACTIONS None FISCAL IMPACT No immediate impact.
