BACKGROUND: The City of Moorpark periodically adopts by reference the various building related codes for the City after they have been developed and approved by the State. The last updates were in 1997. DISCUSSION: The various building related codes are periodically updated and reviewed by the State for use in California. The most revisions have been made and are prepared for adoption by the City of Moorpark. Cities have the opportunity to make modifications to the state codes to reflect local concerns. If local action is not taken and local ordinance is not in effect on July 1, the State's adopted Code automatically are placed in effect in the City. The current editions proposed for adoption are: Uniform Building Code, Volumes 1, 2 & 3, 1997 Edition with Appendix ( ) 0 0111 iI Ordinance No. - Code Adoption Meeting of 21 April 1999 Page 02 National Electrical Code, 1996 Edition Uniform Plumbing Code, 1997 Edition Uniform Mechanical Code, 1997 Edition Uniform Housing Code, 1997 Edition Uniform Code for the Abatement of Dangerous Buildings, 1997 Edition Uniform Administrative Code, 1997 Edition. Proposed modifications to the Codes are in keeping with previous actions by the City Council. State law provides for a different action for adoption of these Codes by reference. The Council is requested to introduce the ordinance on First Reading at this meeting. It is then advertised two (2) times in a local adjudicated newspaper and a public hearing is set at the time of Second Reading and Adoption, which is scheduled for May 19, 1999.

For the purpose of this code, certain locations within the incorporated areas of the City of Moorpark shall be classified as High Fire Hazard by the Ventura County Fire Protection District. The High Fire Hazard Area is defined as any area within 500 feet of uncultivated brush, grass, or forest - covered land wherein an authorized representative of said district determines that a potential fire hazard exists due to the presence of such flammable growth. Sec. 3602. CONSTRUCTION REQUIREMENT IN HIGH FIRE HAZARD AREAS. The purpose of this Section is to provide a minimum standard for the fire protection of buildings and structures hereafter erected in proximity to areas of the City where concentrations of highly flammable brush, grass, or other combustible growth combined with periods of hot, dry winds create a high fire hazard and where lives and property may thereby be endangered. Buildings or structures hereafter erected, constructed or moved within or into designated high fire hazard areas shall be one of the Types of Construction as defined in this Code and shall meet the requirements of this Section. Although their installation is encouraged, neither manual nor automatic fire extinguishing systems or similar water spraying devices may be substituted for the fire protection set forth herein. 3602.1 ROOFS. Roof coverings shall be class A, or B as specified in Section 1504 of the Uniform Building Code, except that no wooden shakes or shingles, treated or untreated, shall be permitted. 3602.2 EXTERIOR WALLS. Fire - resistive protection of exterior walls and openings, as determined by location and property, shall be as required by Section 503 in the UBC. Exception: No exterior wall covering of a building shall provide less fire resistance than that afforded by; 7/8 -inch exterior cement plaster; 1 -inch nominal thickness solid wood siding; 1/2- inch textured plywood siding having a groove depth of 1/8 -inch or less; 7/16 -inch hardwood siding 5/8 inch particle board, exterior type 2 -M; or 5/8 exterior plywood, Texture III, having a groove depth of 1/4 -inch or less. Fire - retardant treated or untreated wood shingle or shake siding shall not be permitted. 3602.3 UNDERFLOOR AREAS. Where under floor areas are not enclosed by fire - resistive construction conforming to the requirements of Section 3601.2 above, the underside of the floor system shall be fire - protected as set forth in Section 3601.4. 3602.4 PROJECTIONS AND OTHER BUILDING ELEMENTS EXPOSED TO FIRE. Architectural projections such as roof overhangs and offsets, balconies and decks, and other elements of buildings which have combustible structural elements in the horizontal plane, shall be protected with materials approved for 1 -hour fire - resistive construction on the lower, fire - exposed side and shall have 1 -hour fire - resistive supporting columns unless the details of construction conform to those for heavy timber as described in Section 605.6 in the UBC. Exceptions: 1. Combustible structural members in horizontal projections may be unprotected timbers of size 4x6 or larger when used as rafters or as stair, balcony, or deck supports or for similar purposes. 2. Heavy timber roof decking at eaves and rakes may be unprotected provided a fascia of not less than 2 -inch nominal thickness and not less in depth than the cut end of the rafter is installed at the roof's edge. 3. Patios, carports, arbors and open latticework sunshades may be constructed of any materials allowed by this Code. 4. Balconies and decks 30 inches or more above grade may have flooring of not less than 2 -inch nominal thickness lumber or material of equivalent fire resistance. Such flooring may be spaced not more than 1/4 inch apart and need not be fire protected on the underside. 5. Balconies and decks less than 30 inches above grade shall be solidly floored without gaps and shall be fire - protected on the underside as required by this Section. In lieu of fire protection, such balconies and decks may be enclosed from floor surface to grade in the manner prescribed for exterior walls in Section 3602.2. 6. Combustible exterior columns directly supporting roofs, stairs, balconies, and decks may be size 4x4 or larger. Columns and beams supporting interior floor loads may be size 6x6 or larger. 3602.5 VENTILATION OPENINGS. Attic or foundation ventilation openings or louvers shall not be located at or immediately below, eaves, or rakes, offsets or balconies, or similar exterior overhangs which may be directly exposed to a fire in adjacent hazardous grass or brush areas. Section 3603. WAIVER OF REQUIREMENTS. The Building Official may waive the requirements of UBC Sec. 3601.1 through 3602.5 above, in whole or in part, for specific construction projects within the High Fire Hazard Area when such waiver is approved by an authorized representative of the Ventura County Fire Protection District, based upon site conditions which justify a reduction in fire resistance. 15.08.090 FOUNDATION INVESTIGATION. Section 1804.2 and 1804.7 are hereby amended to read: Section 1804.2 INVESTIGATION. The classification of soil shall be based on observation and necessary tests of the materials disclosed by borings or excavations made in appropriate locations. Additional studies may be required to evaluate soil strength, the effect of moisture variation on soil bearing capacity, compressibility, liquefaction and expansiveness. Whenever, in the opinion of the Building Official, the adequacy and stability of a building site cannot be determined by the test borings or excavations required by this Section, he may require a special geologic, hydrologic, seismic, or other investigation and report. Geologic investigations such as those for hillside stability or seismic hazards shall be conducted by California- certified Engineering Geologist.

For the purpose of this Article certain terms are hereby defined as follows: "Pool" shall mean any body of water created by artificial means which is designed or used for swimming or immersion purposes by men, women, or children and which has a water depth exceeding twenty -four (24) inches. The term "pool" shall include swimming pools, spas, hot tubs and above and below ground vinyl - lined pools but does not apply to plumbing fixtures such as bathtubs; nor does it apply to man -made lakes, reservoirs, or farm ponds used primarily for public park purposes, water conservation, irrigation, or watering of livestock. Section 3702 POOL DESIGN AND CONSTRUCTION. 3702.1 GENERAL. Pool design and construction shall be in accordance with accepted engineering practice, shall be in conformity with applicable provisions of the adopted building, electrical, plumbing, and mechanical codes, and shall be structurally suitable for the soil, topographic, and geologic conditions prevailing at the construction site. 3702.2 EXPANSIVE SOIL DESIGN. Pools constructed at grade shall be designed on the assumption that their construction is to be in an area of moderately expansive soil having an expansion index of 51 -90 and an equivalent fluid pressure of not less than 45 pounds per cubic foot (45 p.c.f.) . Exception: Where tests indicate that soils at a pool site are non - expansive or have low expansion characteristics from the ground surface to the full depth of the pool, structural design may be based on an equivalent fluid pressure not less than 30 p.c.f. In highly expansive soils having an expansion index of 91- 130, pools shall be designed for not less than 60 p.c.f. equivalent fluid pressure. In very highly expansive soils having an expansion index over 130, pool design shall be subject to special requirements based on a site investigation, soil testing, and engineering analysis by a registered civil engineer to determine appropriate design parameters for the site. 3702.3 HYDROSTATIC UPLIFT. In areas of anticipated high water table, an approved hydrostatic relief system or device shall be installed. 3702.4 THERMAL PROTECTION FOR PLASTIC PIPING. Between the inlet of pool water heating equipment and any plastic water piping connected thereto, a check valve shall be installed to prevent thermal damage to such piping due to backflow. Exception: When rapid or high -rate filters are employed, a check valve may be omitted. Between the outlet of pool heating equipment and any plastic water piping connected thereto, not less than five feet of approved metal pipe shall be installed for the purpose of dissipating heat. 3702.5 SAFEGUARDING SUCTION DRAINS. Bottom drains and suction intakes in pools and spas shall be covered with grated or other protective devices which cannot be removed except with tools. The slots or openings in these covers shall be of such area, shape, and arrangement as to prevent bathers from being drawn thereto with such force as to constitute a safety hazard. 3702.6 GRAB BARS. Wherever egress from a pool by bathers is restricted by the presence of a vertical wall or other barrier which extends more than 12 inches above the water at the pool's edge, permanent handrail, grab bars, or equivalent device (s) shall be installed within 12 inches of the water surface, capable of being securely grasped and adequate to support the weight of a user of the pool. Section. 3703 DECKS 3703.1 GENERAL. A deck shall be provided around below - grade swimming pools except when special engineering design is furnished which indicates that such deck is not necessary for the purpose of maintaining the structural integrity of the pool and /or for controlling surface water and moisture content in the soil adjacent to the pool. Decks shall not be required for spas and hot tubs. 3703.2 DECK DESIGN AND CONSTRUCTION. Required decks shall be constructed of concrete or other approved impervious material and shall be sloped to provide positive drainage away from the perimeter of the pool. Except as provided below, decks shall have a minimum width of four feet and shall be at least 3 -1/2 inches in thickness. Reinforcement shall be #3 bars spaced not over 24 inches o.c. each way, or equivalent reinforcing, Approved joints shall be provided in the deck at corners, at maximum 10 -foot intervals, and wherever necessary in order to control cracking, to allow for differential movement and to minimize damage to the deck from such movement should it occur. Joints in decks and coping shall be made watertight with an approved permanent resilient sealant. 006168 3703.3 CUTOFF WALLS. At the outer perimeter of pool decks a cutoff wall of approved material shall be installed below -grade to a depth of at least 15 inches so as to form a permanent and effective vertical moisture barrier. Exception: 1. A cutoff wall may be omitted when a deck at least six feet wide is installed. 2. Decks less than four feet in width may be installed provided that the required cutoff wall is increased in depth beyond the minimum by an amount directly proportional to the reduction in deck width. 3703.4 PRE - SATURATION, HIGHLY EXPANSIVE SOILS. When the soil below a deck has an expansion index of 91 or greater it shall be saturated with water to a depth of at least 18 inches prior to installation of the deck. Section 3704. DRAINAGE AND DISPOSAL 3704.1 SURFACE WATER. Surface water from pool decks shall be collected and conducted through non - erosive devices to a street, storm drain, or other approved watercourse or disposal area. 3704.2 WASTEWATER. Pool waste shall be disposed of in accordance with the requirements of the Health Officer. 3704.3 DRYWELLS.
