General Findinqs. The Dublin City Council makes the following general findings regarding local climatic, geologic, and topographical conditions, which the City Council finds necessitates the local modifications to the California Building Standards Code set forth below: Local climatic conditions include a low amount of average yearly rainfall, which tends to be concentrated from October through April. From May through September, a dry period occurs where daily temperatures remain high and there is little measurable precipitation. In addition, the local climate frequently includes high winds which sweep down through the valley. As a result of the high summer temperatures, average load demand and peak load demand of energy used in Dublin are important factors impacting public safety and creating the potential for adverse economic impacts due to power outages or power reductions (i.e. "brownouts"). As a result of the low precipitation, the area is subject to occasional drought. In developed areas of the City, fires can occur in buildings, rubbish, automobiles, and grass fires on vacant lots. In the undeveloped areas of the City, there is a risk of large brush and grass fires. !f a fire occurs in either a developed or undeveloped area of the City, the local dry conditions combined with high winds, creates the risk of a potential fire storm. In addition, focal residential development is occurring in previously undeveloped areas adjacent to wild fire hazard areas. These new developments increase the chance of fire while simultaneously being located further from fire stations, delaying critical response times. 2. Local geographical conditions include a risk of earthquake. A number of earthquake faults are located either within or in close proximity to the City. Those with the most direct and potentially destructive impact are the San Andreas, Calaveras, Hayward, Greenville and Concord-Green Valley Faults. History of earthquake activity indicates that there is a likelihood of a major earthquake in the area. In the event of an earthquake, damage to structures can be expected. In residential and commercial areas, this could include significant damage or collapse of buildings. Secondary impacts could include ruptured electric or gas connections and/or breaks in water distribution lines. The potential for a major seismic event would create a City-wide demand for emergency response and fire protection service which would exceed staff response capacity. 3. Local topographical conditions include hills on the western and eastern boarders and flat area in the center of the City. Interstate 680 divides the City into two sections, and circulation between areas of the City rely on freeway overpasses. In addition, local traffic must also pass over railroad tracks, creeks, and bridges (to cross arroyos). ATTACHMENT 1 Page 1 of 42 EXHIBIT A ! ~ X' ` ~Lf ~ ~~, During peak a.m. and p.m. traffic periods, the City experiences heavy traffic congestion at key intersections, and near many freeway on-ramp and off-ramps. In the event of an accident or emergency at one of these key intersections, bridges, or other circulation corridors, sections of the City could become isolated and response times increased beyond ideal levels. 4. Based on the local climatic, geographical, and topographical conditions outlined above, there is a real risk that emergency response could be significantly delayed in the event of an accident or emergency. Therefore, it is necessary to address this problem through the requirement of additional mitigation measures to: (i) prevent the chance of accident or injury by requiring standards more stringent than required by the current codes; and (ii) requiring additionaf built-in automatic fire protection systems which will provide for early detection and initial fire control. B. Specific Findings: The Dublin City Council makes the following specific findings, which, in addition to the general findings regarding local climatic, geologic, and topographical conditions set forth above, the City Council finds necessitate the local modifications to the California Building Standards Code set forth below: 1.

Section R902.1 is amended to read: R902.1 Roof covering materials. Roofs shali be covered with materials as set forth in Sections R904 and R905. Class A, B or C roofing shall be installed in areas as designated below. Classes A, B and C roofing required by this section to be listed shall be tested in accordance with UL 790 or ASTM E 108. 1. Map of Fire Sa#e Roof Areas. Figure 15-1* is a map of Fire Safe Roof areas. Said map may be amended from time to time by including areas which are annexed to the City within one of the two roofing areas. Said amendments may be made by the Building Official after consultation, with the Chief of the Fire Department or their designee having jurisdiction. 2. Roofing Area 1. Any new roof and any alteration, repair or replacement for buildings housing R& U-1 occupancies in Roofing Area 1 shall use roof covering material that conforms to Class B or better or shall be made of concrete, ferrous or copper metal, clay, slate or similar non-combustible material. 3.

Any new roof for buildings using roof covering material that conforms to Class C or better or shall be made of concrete, ferrous or copper metal, clay, slate or similar non-combustible material. *Editor's Note: Figure 15-1 is on file in the office of the City Clerk. FINDING: The amendment is needed due to local climatic and topoqraphical conditions. This modification was necessary because the City of Dublin has a drv period of at least five months each vear. Additionally, The area is subiect to occasional drouqht. Because of drvness, a rapidly burninq qrass fire or exterior buildinq fire can quickly transfer to other buildinqs. These modifications are consistent with the Fire Authority havinq iurisdiction. 7.34.210 Section R1001.1.2 Chapter 10, Prohibited Installations-Added. A new Section R1001.1.2 is added to read: It shall be unlawFul to install a new wood burning fireplace or appliance that is not one of the following: 1. Pellet-fueled wood heater, 2. EPA certified wood heater, Page 36 of 42 3. Fireplace certified by EPA ~ ~ .~;~. _ ~ 4 ~ FINDING: The amendment is needed due to local climatic and topoqraphical conditions. This modification was necessarv because fireplaces and wood stoves generate 40 percent of the particulate matter in the Bav Area durinq the winter months. Of qreater concern are the fine particles, which can lodqe deep in the lunqs causinq permanent lunq damaqe and increasinq mortality Burninq wood also qenerates carbon monoxide, nitroqen dioxide, volatile orqanic and toxic air pollutants. 4. California Electrical Code, Section 7.36.080 DMC Section 210-53, Office receptacle outlets-Added. Section 210-53 is added to read: Section 210-53 Office Receptacle Outlets. In office buildings or offices exceeding ten (10) percent of the floor area of the major use, receptacle outlets shall be installed in all permanent walls or partitions so that no point along the floor line any wall space is more than six (6) feet (1.83m) measured horizontally, from an outlet in that space including any wall space two (2) feet (610 mm} or more in width and the wall space occupied by sliding panels in exterior walls. As used in the section a"wall space" shall be considered a wall unbroken afong the floor line by doorways, fireplaces, and similar openings. Each wall space two (2) or more feet (610 mm) wide shall be treated individually and separately from other wall spaces within the room. A wall space shall be permitted to include two or more walls of a room (around corners) where unbroken at the floor line. Receptacle outlets shall, insofar as practicable be spaced equal distances apart. Receptacle outlets in floors shall not be counted as part of the required number of receptacle outlets unless located near the wall. The receptacle outlets required by the section shall be in addition to any receptacle that is part of any lighting fixture or appliance, located within cabinets or cupboards, or located over five and one-half (5'/2} feet (1.68 m) above the floor. FINDINGS;_ The amendment is needed due to local qeoloqical conditions This section requires additional receptacles The City of Dublin is located in a hiqhly active Seismic Zone D and E In Office Buildinqs without these requirements extension codes are beinq used Extension cords are not afforded the same protection from damaqe as wirinq racewavs Damaqe to extension cords could occur in a seismic event which increases the po#ential for a fire. 5. California Plumbinq Code. Section 7.40.080 DMC Section 609.3, Chapter 6 UPC, Water piping in slab floors- Amended.

When approved; such piping shall be installed in accordance with the following requirements: FINDINGS The amendment is needed due to local qeoloqical conditions. This section eliminates water pipinq in or under concrete floor slabs within a buildinq. This amendment is necessary for the followinq reasons: (1) Most of the surface soits in the Citv of Dublin are relatively younq and unconsolidated sedimentarv ma#erials formed from a wide variety of parent materials. The varving chemical composition, deqree of weatherinq and the relativelv acid environment have created soils of varvinq types, which are particularly corrosive in nature. (2~ Much of the surface soil in the City of Dublin is hiqhly expansive (i.e., shrink- swell behavior) and have low bearinq strenqth. (3) There are two types of expansive soils in the area: a. the orqanic siltv clavs which are the recent bav muds; and b. the plastic siltv clavs which weather from the shale found in the hills surroundinq the Citv of Dublin (4) The loca! climate is characterized bv markedlv delineated rainv and drv seasons, which tend to maximize the expansive characteristics of soil. (5) Some parts of the Citv of Dublin have hard water, which is corrosive to ferrous pipe. (6) The qroundwater table is unusuallv hiqh in many places. (7) The Citv of Dublin is a hiqhly active seismic area. 6. California Mechanical Code No modifications necessitating specific findings are adopted. 7. California Green Buildinq Code 7.94.040 Scope.

A. Covered projects shall achieve a minimum Green Building Program Rating of fifty (50) points under the Green Building Program Checklist for single-family housing. All multi-family residential projects shall achieve a"green home" or similarly entitled minimum compliance rating system, which currently requires fifty (50) GreenPoints, or a minimum Green Building Program Rating of fifty (50) points under the Green Building Program Checklist for multi-family housing, unless the Building Official determines that the single-family green building rating system is more appropriate for the building, such as for a duplex building that is part of a larger project. Approval of a building permit for new construction shall not be granted unless the Applicant submits a checklist demonstrating the covered project receives the minimum Green Building Program Rating required on the appropriate Green Building Program Checklist. All mixed-use projects shall meet the requirements for a multi-family residential project, unless the Building Official determines the Green Building Code or another rating system is more appropriate. B. In the event that an Applicant wishes to use an alternative green buitding standards program other than the GreenPoint rating system or the LEED~' for Homes Green Building Rating System, the Applicant may apply to the Building Official for approval of the alternative program. The Applicant must submit Green Building Documentation showing that the Applicant's utilization of the alternative program will result in green building benefits that are better than the benefits that would be achieved by obtaining a Green Building Program Rating of fifty (50) points under either the GreenPoint rating system or the LEEDtm for Homes Green Building Rating System. Any proposed alternative green building program must be created by a third-party entity not under the control of the Applicant, and must be sufficiently similar in structure to the GreenPoint Page 41 of 42 ~f ~- .~~ I~ I rating system and the LEEDtm for Homes Green Building Rating System to allow the Bu~lding Official to administer the requirements of this Chapter to the alternative green building standards program without significant deviation. At a minimum, the alternative green building standards program must utilize a checklist structure similar to the Green Building Program Checklists. No Applicant may utilize an alternative green building standards program unless the Building Official gives the Applicant written approval of the Applicant's proposed utilization of the program.
