I ' STAFF REPORT SUBJECT Urgency Ordinance and regular Ordinance of the City of San Bernardino amending Chapter 15.10 of the San Bernardino Municipal Code relating to Foothill Fire Zone Building Standards and adding Chapter 15.11 of the San Bernardino Municipal Code to include the Building Safety Enhancement Area Building Standards. BACKGROUND The California Fire Chiefs Association Urban-Wildland Interface Committee has analyzed contributing factors associated with structure loss during the Old Fire. Subsequently, they held a series of meetings to develop recommended construction changes in our foothill area (attachment A). The primary purpose of these changes is to reduce the potential for future conflagration with these buih-in construction features. The Mayor appointed an Ad Hoc committee to discuss the proposed ordinance and submit recommendations to the Legislative Review Committee (LRC). On December 29, 2003, the Ad Hoc committee recommended that the draft Urgency Ordinance and regular Ordinance be presented to the LRC for approval. On December 30, 2003, the Fire Department presented a draft Urgency Ordinance and draft regular Ordinance to the LRC requesting authorization to amend the existing Foothill Fire Zone Building Standards of the San Bernardino Municipal Code and to add the Building Safety Enhancement Area Building Standards. The Committee recommended that the Urgency Ordinance and regular Ordinance be presented for adoption at the January 5, 2004 Council meeting. Amending Chapter 15.10 of the San Bernardino Municipal Code will implement a number of minor changes recommended by the Urban-Wildland Interface Committee. Adopting Chapter 15.11 of the San Bernardino Municipal Code will provide a procedure for the Council, by resolution, to designate certain areas as Building Safety Enhancement Areas subject to specific building standards that will help mitigate the threat of future conflagration. The following is a summary of proposed building requirements detailed in Chapter 15.11: . Exterior walls are to be constructed of non-combustible materials or a minimum of 1- hour tire-resistance-rated construction. . Eaves are to be enclosed with a minimum 7/S-inch stucco or equivalent. . Vinyl window frame assemblies would be required to meet certain specifications. . Garage doors are to be constructed of non-combustible materials or tire- retardant treated wood. . Attic vents must be covered with 1/S" mesh screening; additionally, turbine type vents would not be permitted. 1 . Type of insulation and roof covering would also be regulated. . When wood fencing is used, there must be a five-foot separation distance between the wall of the nearest structure and the wood fence. Fencing within the five-foot separation area is to be non-combustible material or I-hour fire-resistance-rated construction. Except where construction occurred pursuant to a previous Code. Most of these new requirements are currently found in the Foothill Fire Zone Building Standards. Homes constructed with these built-in protections sustained much less damage, if any, during the Old Fire. A strike out version of the ordinance is attached for your review. FINANCIAL IMPACT There is no financial impact to the City of San Bernardino. RECOMMENDATION That said ordinance be adopted. 2 " porn.O.._-Murphy Pruldent Lalllll BIauI ,.

DATE: November 14,2003 TO: Larry Pitzer, Fire Chief Doug Dupree, Fire Marshal City of San Bernardino Fire Department FROM: Urban-Wildland Interface Committee SUBJECT: Old Fire, October 25 - November 5, 2003 During the recent "Southern California Wildfire Siege", all.areas of Southern California felt the impact of the fires, with the City of San Bernardino receiving one of the most significant blows. The wind-driven "Old" Fire began on the morning of Saturday, October. 25,2003, and proceeded to bum over 91,000 acres and destroyed or damaged 1038 structures before being contained on November 5.' 336 homes were lost or damaged within the boundaries of San aernardino - the majority of which were located in the north Del Rosa area. . The Urban-Wildland Interface Committee is extremely saddened to see the havoc wreaked by the Old Fire on your city. The losses to private and public properties are enormous, and will have many long- as well as short- term effects. As devastating as the fire was, however, it also provides us an opportunity to observe and learn from what worked and didn't work in the neighborhoods and areas that experienced the high structure losses. We appreciate the opportunity to work with you in surveyil\g and inspecting the damaged areas, and for your support in providing maps and damage data for your city. The attached report of findings, contributing factors and corresponding recommendations are based upon this work. Prepared by: ~~kf~ Rolland M. Crawford .. Co-Chair Urban-Wildland Interface Committee p~.~ Leonard Temby Committee Member Urban-Wildland Interface Committee Attachment A ., . - . INITIAL REPORT OF FINDINGS AND RECOMMENDATIONS For the DISASTER WITHIN THE CITY OF SAN BERNARDINO CAUSED BY THE EFFECTS OF THE OLD FIRE, 2003 , Introduction The "Old" Fire (taken from "Old Waterman") began on the morning of Saturday, October 25, 2003, and proceeded to burn a total of91,281 acres and destroyed or damaged 1038 structures before being 100% contained on November 5 (993 homes destroyed, 35 homes damaged, 10 commercial structures destroyed). 336 structures were lost or damaged within San Bernardino - the majority of which were located in the north Del Rosa area. Fire response costs to date exceed $42,500,000. Members of the UWI Committee, principally the authors of this document, have made several surveys of the affected areas, conducted interviews with residents and respondin~ firefighters, along with analysis of fire loss maps and loss/damage data and photographs taken during the initial attack phase of the fire. We have performed inspections of individual properties that were either not damaged, or minimally damaged, while numerous surrounding structures were . destroyed or severely damaged. The following findings and corresponding recommendations are based upon this work. Findings I. Wind-driven fire. The fire front that entered the Del Rosa area has been described as "like a wave of flame coming down off the hills" onto the structures situated at the north end of Quail Canyon Road. The winds driving the fire have also been described as very erratic, changing direction and intensity on a frequent basis. In some instances, structures at the true wildland fuels interface area were hit with direct flame impingement, while others were subjected to considerable amounts o(wind-carried buming debris. 2. Transmission of fire. The fire that swept down off the foothills into the built-up areas was propagated to structures by a combination of factors. These included direct flame impingement, ignition of trees allowed too close to structures (I(.g., limbs overhanging roofs and eaves), tree-to-tree flame propagation, flying brands and embers, structure-to-structure flame spread (due to proximity of exterior walls, radiant heat transfer), ignition of combustible fencing and auxiliary structures, ignition of ornamental landscape vegetation (with propagation into structures when planted too close to the structure). Large quantities of flying embers and brands were generated; in many cases these carried considerable distances - a very significant factor. 3. Structure losses. The fire experience in San Bernardino was a combination of a true interface fire plus an urban conflagration. This was due to a) Direct flame impingement, b) Burning ember intrusion into attic spaces, usually via vents, c) Entrapment of burning materials under roof assemblies. . ~> A'- . ., Major Contributing Factors . Structure ignition caused by wind-blown firebrands and embers landIng in or under roofing materials, or through entry into attic spaces through vents or other means. Vent placement appears to be a primary concern (i.e., where placed cjn the structure in relationship to wildland areas). Another concern is the entry of burning embers into attics through rooftop-mounted turbine vents. . Ornamental landscape vegetation providing a ready path for flame propagation into structures, and/or causing production of significant of flying embers !md brands. . Ignition of combustible materials in and around yards, such as wood~ fences, overgrown vegetation, storage, woodpiles, etc. These materials ofteriprovided a source of ignition to the adjacent home. . Extremely restricted roadway access in certain areas, especially in and around Quail Canyon. . Structure-to-structure fire propagation caused by direct flame impingement or radiant heat due to close proximity of houses. Recommendations 1. Increase the boundaries of the designated Hazardous Fire Area (Foothill Fire Zone), and implement an additional buffer or threat zone further south into the existing built- up neighborhoods and areas. 2. Consider adoption of the International Urban- Wildland Interface Code, or at least certain key provisions, as a minimum. For example, see Chapters 4, S, 6, and Appendices B and F, included in Attachment 1. 3. Limit vegetative fuels. As part of the Building Permit process for new developments or projects, require submittal of a landscaping plan, specifically consl4ering species selection, plant placement (in relationship to structures and other plants), and on- going maintenance. Prepare guidelines for use by new and existing h~meowners and landscape designers, especially noting plant species that should not b~ used due to their readily ignitable nature (high oil or resin content, production of ~ignificant amounts of dead material or debris, etc.), plant placement in relation io other landscaping materials and residential structures, and on-going landscape maintenance considerations. 4. Establish interface fuel modification zones. Implementation of a fuel'break along the north perimeter of the built-up area, adjacent to the vegetated wildIanll areas. , 5. Adopt additional building design and construction standards specifically regulating placement of attic vents on the side(s) away from the wildland area, provide adequate stopping for open ends of roof covering materials (e.g., "bird stops" at the open ends of roofing tiles). For example, see text included in Attachment 2.

The following findings are hereby made: . 24 25 26 27 28 A. All areas of the City are subject to periods of elevated temperatures and high winds known as Santa Ana conditions, and Such Santa Ana conditions have the potential to spread urban fires from structure to structure and across property lines, and Past conflagrations such as the Panorama Fire, the Old Waterman Canyon Fire, and other fires have resulted in substantial fire losses and indicate that the spread of fire B. c. HElj s[ urgency .ordinance. 6 ] 4 . . . r 1 poses a substantial threat to life and property, not only in the Foothill Fire Zones, but in urbanized areas as well. 2 3 SECTION 4. Statement of Urgency. This Ordinance is being proposed as an Urgency Ordinance due to the recent fire and 4 subsequent loss of structures in the city during the fire. Immediate adoption is necessary because of the fire danger that exists and the growing number of applications to rebuild fire 5 damaged/destroyed structures. Previously adopted built-in construction features significantly reduced the damage in the Foothill Fire Zone. It is imperative that these standards are adopted 6 immediately for new construction in the Building Safety Enhancement Areas designated by the Mayor and Council and those specified new residential housing tracts and commercia] structures. 7 The primary purpose of these changes is to reduce the potential for future conflagration with these built-in construction features. 8 III 9 III 10 /II II III 12 III 13 III 14 III ]5 /II ]6 III 17 III 18 /II 19 /II 20 1/1 21 /II 22 /II 23 III 24 III 25 /II 26 /II 27 III 28 HElj s [ urgency .ordi nance. 6 ] 5 . . 18 19 20 21 22 23 24 25 26 . 27 28 . 1 URGENCY ORDINANCE OF THE CITY OF SAN BERNARDINO AMENDING CHAPTER 2 15.10 RELATING TO FOOTHILL FIRE ZONE BUILDING STANDARDS AND ADDING CHAPTER 15.11 OF THE SAN BERNARDINO MUNICIPAL CODE TO INCLUDE THE 3 BUILDING SAFETY ENHANCEMENT AREA BUILDING STANDARDS. 4 I HEREBY CERTIFY that the foregoing Ordinance was duly adopted by the Mayor and Common 5 Council of the City of San Bernardino at a meeting thereof, held on the _ day of 6 , 2004, by the following vote, to wit: 7 COUNCIL MEMBERS: 8 ESTRADA 9 LONGVILLE 10 MCGINNIS 11 DERRY 12 SUAREZ 13 ANDERSON 14 MCCAMMACK AYES NAYS ABSTAIN ABSENT 15 16 17 City Clerk The foregoing Ordinance is hereby approved this _ day of ,2004.

The following findings are hereby made: . 26 27 28 A. All areas of the City are subject to periods of elevated temperatures and high winds known as Santa Ana conditions, and Such Santa Ana conditions have the potential to spread urban fires from structure to structure and across property lines, and B. HElj s[ urgency. ordinance. 5] 4 . . . 1 c. Past conflagrations such as the Panorama Fire, the Old Waterman Canyon Fire, and other fires have resulted in substantial fire losses and indicate that the spread of fire poses a substantial threat to life and property, not only in the Foothill Fire Zones, but in urbanized areas as well. 2 3 SECTION 4. Statement of Urgency, 4 This Ordinance is being proposed as an Urgency Ordinance due to the recent fire and 5 subsequent loss of structures in the city during the fire. Immediate adoption is necessary because of the fire danger that exists and the growing number of applications to rebuild fire 6 damagedldestroyedstructures. Previously adopted built-in construction features significantly reduced the damage in the Foothill Fire Zone. It is imperative that these standards are adopted 7 immediately for new construction in the Building Safety Enhancement Areas designated by the Mayor and Council and those specified new residential housing tracts and commercial structures. 8 The primary purpose of these changes is to reduce the potential for future conflagration with these built-in construction features. 9 //f 10 //f 11 //f 12 //f 13 //f 14 //f 15 //f 16 //f J7 //f 18 //f 19 //f 20 //f 21 //f 22 //f 23 //f 24 //f 25 //f 26 f// 27 //f 28 HEljs [ urgency .ordinance. 5} 5 . . 18 19 20 21 22 23 24 25 26 . 27 28 . 1 URGENCY ORDINANCE OF THE CITY OF SAN BERNARDINO AMENDING CHAPTER 2 15.10 RELATING TO FOOTHILL FIRE ZONE BUILDING STANDARDS AND ADDING CHAPTER 15.11 OF THE SAN BERNARDINO MUNICIPAL CODE TO INCLUDE THE 3 BUILDING SAFETY ENHANCEMENT AREA BUILDING STANDARDS. 4 I HEREBY CERTIFY that the foregoing Ordinance was duly adopted by the Mayor and Common 5 Council of the City of San Bernardino at a meeting thereof, held on the _ day of 6 , 2004, by the following vote, to wit: 7 COUNCIL MEMBERS: 8 ESTRADA 9 LONGVILLE 10 MCGINNIS 11 DERRY 12 SUAREZ 13 ANDERSON 14 MCCAMMACK AYES NAYS ABSTAIN ABSENT 15 16 17 City Clerk The foregoing Ordinance is hereby approved this _ day of ,2004.
