WHEREAS, the City Council proposes to approve ordinances adopting the 1988 editions of the Uniform Building Code and the Uniform Housing Code and other uniform codes published by the International Conference of Building Officials; and WHEREAS, the City Council considers it necessary, because of local climactic, geological or topographical conditions, to amend certain building standards in the Uniform Building Code and the Uniform Plumbing Code, 1988 editions, as hereafter set forth; and WHEREAS, pursuant to sections 17958.5, 17958.7 and 18941.5 of the Health and Safety Code of the State of California, the City Council is required to make findings that such amendments are necessary due to local climactic, geological, or topographical conditions, and to file such findings, together with the amend- ments, with the Department of Housing and Community Development of the State of California; NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF SANTA ANA AS FOLLOWS: 1. Section 8-61 of the Santa Ana Municipal Code amends, and will continue to amend, section 104 of the Uniform Building Code as follows: "Sec. 8-61. Fire protection requirements (Section 104(b)). Subsection (b) of Section 104 of the Building Code is amended by adding thereto the following: EXCEPTION: If additions, alterations or repairs made to any building constructed prior to January 1, 1946, other than an R-occupancy building, exceed twenty thousand dollars ($20,000.00) in cost any one- year period, then either (A) the entire building must be completely sprinklered in accordance with fire department standards, or (B) the building must comply with all the following requirements: The ceiling of a roof system shall be of one-hour constructon, and all ceiling or wall penetrations shall have approved fire dampers. 320 RESOLUTION NO. 90-087 PAGE TWO Ail stairways shall be completely enclosed with one-hour construction to exits; and enclosed stairways or required exits shall lead directly to the outside of the building. Fire stops are required in floors in accordance with Section 2517(f)2. In attic areas, one-hour walls shall be required for every one thousand (1,000) square feet of area. Smoke detectors with an alarm system, receiving their primary power from the building wiring, shall be required through- out the building in accordance with NFPA standards. Either (a) corridors, regardless of occupant load, shall be one-hour construction; or (b) a "life safety" sprinkler system, as approved by the fire department, shall be installed in all corridors." The City Council hereby finds and determines that there are numerous pre-1946 buildings in downtown Santa Ana, that such buildings are particularly vulnerable to earthquakes and to earthquake-caused fires, that earthquakes are a common occurrence in the local area, and that the above amendment is necessary to address the enhanced risk of fire in such buildings. 2. Proposed sections 8-169 and 8-170 of the Santa Ana Municipal Code will amend the Uniform Building Code as follows: "sec. 8-169. Re-roofing (Section 3210). Section 3210 is added to the Building Code, to read as follows: Sec. 3210. Ail re-roofing shall conform to the applicable provisions of Chapter 32 and Appendix Chapter 32 of this code. Roofing materials and methods of applica- tion shall comply with the Uniform Building Code Standards or shall follow the manufacturer's installation requirements if approved by the building offical. 32 1 RESOLUTION NO. 90-087 PAGE THREE Exception 1: Re-roofing of Group R, Division 3 and Group M occupancies may be done with wood shingles and shakes conforming to Table 32-B-2 and Table 32-C if the original or existing roof covering consisted of wood shingles or shakes. Exception 2: Notwithstanding the provisions of Section 104(b), once during any twelve-month period, any existing roof covering may be replaced with the same kind of covering if the replacement area does not exceed fifty (50) per cent of the gross roof area." "Sec. 8-170. Minimum roof classes (Table No. 32-A). Table No. 32-A of the Building Code is amended in the following respects. (1) Wherever the symbol NR (Nonrated roof coverings) appears, it is replaced by the symbol C (Class C roofing). (2) Footnote 2 is deleted." The City Council hereby finds and determines that the "Santa Ana winds" conditions which occurs frequently in the local area presents a special hazard of spread of fire from one rooftop to another, and the above amendments are necessary to address this risk. 3. Sections 8-400, 8-401, and 8-402 of the Santa Ana Municipal Code amend, and will continue to amend, the Uniform Plumbing Code as follows: "Sec. 8-400. Water piping in buildings (Section 1008(c)(1)). Subsection 1008(c)(1) of the Uniform Plumbing Code is amended to read as follows: (1) Non-metallic and ferrous piping shall be prohibited; except that ferrous piping four (4) inches and larger may be used when protected against corrosion and installed in channels, tubes, or in a similar protective manner when approved by the administrative authority." RESOLUTION NO. 90- 087 PAGE FOUR "Sec. 8-401. Building supply pipe (Section 1009(h)). Section 1009(h of amended by changing the third paragraph to read the Uniform Plumbing Code is second paragraph and adding a as follows: (h) Size of meter and building supply pipe using Table 10-2. Knowing the available pressure at the water meter or other source of supply and after subtracting one-half (1/2) pound per square inch pressure for each foot of difference in elevation between such source of supply and the highest water supply outlet in the building or on the premises, use the "Pressure Range" group within which this pressure will fall. Select the "length" column which is equal to or longer than the required length. Follow down the column to a fixture unit value equal to or greater than the total number of fixture units required by the installation. Having located the proper fixture unit value for the required length, sizes of meter and building supply pipe will be found in the two (2) left-hand columns. Each single family residential structure shall be served with a main water supply pipe of not less than one (1) inch I.D. Two (2) hose bibbs served by inch I.D. Pipe or larger shall be serving the front yard and one (1) yard." three-quarter (3/4) provided; one (1) serving the rear "Sec. 8-402. Building supply pipe (Table 10-2). Table 10-2 of the Uniform Plumbing Code is amended by changing the double asterisk footnote to read as follows: **Building Supply--3/4" minimum--l" minimum for each single family residential structure. The City Council hereby finds and determines that soils are corrosive in the local area and that the above amendments are necessary to prevent pipe corrosion. The City Council also finds and determines that the larger pipe size required by the above amendments is necessary to provide adequate irrigation for residences due to the dry climate of the local area. 323 RESOLUTION NO. 90- 087 PAGE FIVE 4.
