Section 8-340 of the Santa Ana Municipal Code will amend section 314.3 of the Uniform Plumbing Code to read as follows: 314.3 Piping in the ground shall be laid on a firm bed for its entire length. Building drains, sewers and storm drain piping systems in the ground, and designed and approved at less than one percent grade, shall be laid on a continuous firm bed, cer- tified by a registered soils engineer as having a compaction level of not less than ninety (90) per- cent density. Where support is otherwise provided, it shall be acceptable to the Administrative Au- thority. Also, Section 8-405 of the Santa Ana Municipal Code will amend section 718.1 of the Uniform Plumbing Code by adding the following paragraph thereto: Building sewer piping systems designed for grades of RESOLUTION 95-081 313 less than one percent shall be designed by a regis- tered civil engineer. The engineer shall be respon- sible for supervising the installation and shall certify in writing that the sewer installation is in compliance with the approved plan, relative to line and grade. With respect to these two amendments, the City Council finds and determines as follows: These amendments are necessary because of problems which have arisen in excessively flat-graded drain systems. Santa Ana's sewer system in many areas is relatively shallow. This has precluded the design and installation of drainage systems with recommended grades. Additionally, many areas of Santa Ana have a high water table which results in an unstable soil condition. Pipe settlement due to uncompacted soil may result in a drainage system which is flat or reverse graded, causing stoppages or complete blockage of the drainage system. 2. Section 8-341 of the Santa Ana Municipal Code will amend section 314.7 of the Uniform Plumbing Code to read as follows: 3~4.7 Horizontal cast-iron drain, waste, and vent piping, and all other suspended horizontal piping two and one-half (2~) inches and larger, shall be supported with approved rod and hangers. Exception: Plumbers tape (perforated strap-iron) may be used to support piping 2" and smaller in type V (wood) construction only. Plumbers tape shall be galvanized and not less than 3/4" wide and 22 gage. Also, Section 8-342 of the Santa Ana Municipal Code will amend Table 3-1 of the Uniform Plumbing Code by adding footnote 2 to the requirements for horizontal piping of the following materials: Copper Tube and Pipe; Steel and Brass Pipe for Water or DWV; Steel, Brass and Tinned Copper Pipe for Gas; Schedule 40 PVC and ABS DWV; CPVC; and Lead. With respect to these two amendments, the City Council finds and determines as follows: These amendments are necessary to provide proper support for all horizontal piping because of the significant potential for damage due to seismic activity. Santa Ana is in close proximity to major active fault systems in Southern California. This area has been designated as seismic zone #4, the highest seismic risk zone in a four-tiered hierarchy which rates the potential risk for seismic activity by geographical areas. 3. Section 8-815 of the Santa Ana Municipal Code amends, and will continue to amend, section 210-1 of the National Electrical Code by adding a sentence to read as follows: RESOLUTION 95-081 315 Ail sections of this National Electrical Code allow- ing the use of aluminum conductors are subject to the limitation that no aluminum conductor smaller than No. 6 AWG shall be used. The City Council hereby finds and determines that earthquakes are a common occurrence in the local area; that earthquakes may cause electrical connections and screws to loosen, causing heat problems especially in the smaller sizes of aluminum wire; and that the above amendment is necessary to address the risk of fire due to such causes. 4. Section 8-942 of the Santa Ana Municipal Code amends, and will continue to amend, section 336-4 of the National Electrical Code to read as follows: 336-4. Uses Not Permitted. (a) Type NM or NMe. Types NM and NMC cables shall not be used: (1) in any dwelling or structure ex- ceeding three floors above grade; (2) as service- entrance cable; (3) in any nonresidential building or structure; (4) in hoist-ways; or (5) embedded in poured cement, concrete, or aggregate. For the purpose of this article, the first floor of a build- ing shall be that floor that has fifty percent or more of the exterior wall surface area level with or above finished grade. One additional level that is the first level and not designed for human habita- tion and used only for vehicle parking, storage, or similar use shall be permitted. (b) Type NM. Type NM cable shall not be installed: (1) where exposed to corrosive fumes or vapors; (2) where embedded in masonry, concrete, adobe, fill, or plaster; (3) in a shallow chase in masonry, con- crete, or adobe and covered with plaster, adobe, or similar finish. The City Council finds and determines that earthquakes are a common occurrence in the local area; that, unlike wire installed in conduit or raceways, non-metallic sheathed cable does not provide the degree of protection that is needed in the event of an earthquake; that exposed non-metallic sheathed cable is particular- ly hazardous; and that this amendment is necessary to assure that adequate protection is provided in the workplace and in other places of public gathering. 5. The Clerk of the Council is directed to file a certified true copy of this resolution with the Department of Housing and Community Development of the State of california. 3 RESOLUTION 95-081 317 ADOPTED this 4th ATTEST: C COUNCILMEMBERS: Pulido Aye Richardson Aye Espinoza Aye Lutz Aye McGuigan Aye Mills Aye Moreno Aye day of December , 1995.
