International Fire Code. Where buildings are also of Type I or II construction and are a light-hazard occupancy as defined by NFPA 13, the reduction may be up to 75 percent. The resulting fire flow shall not be less than 1,500 gallons per minute (5678 l/min) for the prescribed duration as specified in Table B105.1.

B105.2 is amended to read:

Buildings other than one-and two-family dwellings. The minimum fire flow and flow duration for buildings other than one-and two- family dwellings shall be as specified in Table B105.1.

Exceptions:

All occupancies within the Central City and High School Redevelopment Districts as defined by Resolutions 2317, 2317.1, and 2588 (to be known collectively as the “Downtown Redevelopment District”) are exempt from the requirements of Table B105.1. All new construction and changes to occupancies within the Downtown Redevelopment District are also exempt from the requirements of Table B105.1 but shall be required to have a Fire Protection System equipped to handle the fire flows required by Table B105.1.

2. A reduction in required fire flow of up to 50 percent, as approved, is allowed when the building is provided with an approved automatic sprinkler system installed in accordance with Section 903.3.1.1 or

903.3.1.2 of the International Fire Code. The resulting fire flow shall not be less than 1,500 gallons per minute for the prescribed duration as specified in Table B105.1

3. Where buildings are also of Type I or II construction and are light-hazard occupancies as defined by NFPA 13, the reduction may be up to 75 percent. The resulting fire flow shall not be less than 1,500 gallons per minute for the prescribed duration as specified in Table B105.1

4. In H occupancies, no reduction in required fire flow is allowed when the building is provided with an approved automatic sprinkler system installed in accordance with Section 903.3.1.1 or 903.3.1.2 of the International Fire Code. The resulting fire flow shall not be less than 1,500 gallons per minute for the prescribed duration as specified in Table B105.1

5. In buildings with high-piled storage, a reduction in required fire flow of up to 50 percent, as approved, is allowed when the building is provided with an approved automatic sprinkler system installed in accordance with Section 903.3.1.1 or 903.3.1.2 of the International Fire Code.

APPENDIX H SPECIAL FIRE RISK AREAS

Appendix H relating to control and suppression in special Fire Risk Areas is added as follows:

H100 Control and Suppression in Special Fire Risk Areas H101 Scope.

The unrestricted use of grass-, grain-, brush- or forest-covered land in Special Fire Risk Area is a potential menace to life and property from fire and resulting erosion. Safeguards to prevent the occurrence of fire and provide adequate fire-protection to control the spread of fire which might be caused by recreational, residential, commercial, industrial, or other activities conducted in Fire Risk Areas shall be in accordance with Appendix H.

H102 Clearance of Brush or Vegetation growth from Structures: Persons owning, leasing, controlling, operating or maintaining buildings or structures in, upon or adjoining Special Fire Risk Areas, and person owning, leasing or controlling land adjacent to such buildings or structures, shall at all times:

1. Maintain an effective firebreak by removing and clearing away flammable vegetation and combustible growth from areas with 30 feet (9144 mm) of such buildings or structures;

Exception: Single specimens of trees, ornamental shrubbery or similar plants used as ground covers, provided that they do not form a means of rapidly transmitting fire from the native growth to any structure.

2. Maintain additional fire protection or firebreak by removing brush,

flammable vegetation and combustible growth located from 30 feet to 100 feet (9144 mm to 30 480 mm) from such buildings or structures, when required by the Fire Chief because of extra-hazardous conditions causing a firebreak of only 30 feet (9144 mm) to be insufficient to provide

reasonable fire safety;

Exception: Grass and other vegetation located more than 30 feet (9144 mm) from buildings or structures and less than 18 inches (457 mm) in height above the ground need not be removed where necessary to stabilize the soil and prevent erosion.

(24)

The Fire Chief is authorized to give notice to the owner of the property upon which conditions regulated by Section 102 exist to correct such conditions and if not corrected abate such conditions in accordance with the provisions of Chapter 8 of the Casa Grande City Code.
