Materials Ordinance through )
Modification of the Uniform )
Building Code as Adopted )
by the City by Reference )
The City Council of the City of Danville DOES ORDAIN AS FOLLOWS:
Section 1. Findings.
Pursuant to Health and Safety Code Sections 17958.5 and 17958.7,
the city Council of the City of Danville hereby expressly finds
that the non-administrative changes set forth below are
reasonably necessary because of certain climatic, geologic and
topographic conditions within the City creating the potential
for extremely uncontrollable and contagious fire situations
which can result in danger to life and property in the
community. These specific conditions are as follows:
1. The climatic conditions within specified areas of the City
of Danville are such that:
- Extensive fire damage may occur due to the ready
ignition, intense burning and rapid spread of fire
involving untreated wood shakes and shingles caused by
dryness, high climatic temperatures and/or winds.
- Extensive fire damage may occur due to the limited
effectiveness and capabilities of the fire district to
control exterior fires due to early exhaustion of
firefighters subject to high climatic temperatures.
- Extensive fire damage may occur due to the susceptibility
of untreated wood shake or shingle roofing and building
exteriors to ignition from other fires involving either
nearby dry vegetation or other buildings, thereby resulting
in multiple fires due to dryness, high temperatures and/or
winds.
- Extensive fire damage may occur due to the reduced
effectiveness of hose streams due to disintegration and
misdirection caused by winds.
1. Subsection (b) of Section 3202, Chapter 32 of the Uniform
Building Code, 1979 Edition, is hereby modified by adding
a second paragraph to read:
"All new roofs for structures with an occupancy
classification of R or M in areas designated on the map
entitled Fire Safe Roof Areas, City of Danville, as
adopted by the San Ramon Valley Fire Protection District
and the City of Danville, shall include roof coverings
with a fire rating of 'A','B', or 'C' which comply with
UBC standard 32-7, or shall be made of material consisting
solely of concrete, metal, slate, or clay tiles, except
for areas designated for unrated roofing material on said
map.
In addition to any other provisions of this Code, fire
retardant roof coverings (Class "A" or "B") shall be
required for all structures of R-1 occupancy
("multi-family residential") where the projected roof area
of any such structure exceeds 3000 square feet.
"Nothing in this section shall limit the City's ability to
require additional fire protection measures, e.g.
sprinklers, fire breaks, emergency access roads, fire
suppression fees, etc. in certain areas warranting
additional protection. Nor shall this section be
interpreted to limit the City's police power in planning
and zoning certain areas for limited development because
of significant fire hazards."
2. Section 3210, Chapter 32 of the Appendix of the Uniform
Building Code, 1979 Edition, is hereby modified by adding
second, third and forth paragraphs to read:
"A building permit shall be required for any roof covering
alteration, replacement or repair for any structure with
an occupancy classification of R or M. Any such roof
covering alteration, replacement or repair not made within
a 12 month period from any similar alteration, replacement
or repair which does not exceed 25 percent of the
projected area of the existing roof, may use materials
similar to those of the existing roof covering.
"Any roof covering alteration, replacement or repair not
made within a 12 month period from any similar alteration,
replacement or repair which exceeds 25 percent but not 50
percent of the projected area of the existing roof shall
utilize fire safe roof covering as specified above for new
roofs.
- Extensive fire damage may occur caused by the ready
ignition of untreated wood shake or shingle roofs exposed
to arcing and sparking of overhead electrical transmission
lines caused by winds.
2. The geologic conditions within specified areas of the City
of Danville are such that:
- Extensive fire damage may occur due to limited
effectiveness and capabilities of the fire district due to
reduced and delayed response of fire companies on arterial
routes obstructed by collapsed overpasses and bridges
and/or landslides caused by earthquakes and/or unstable
soils.
- Extensive fire damage may occur due to limited and/or
delayed response of the fire district due to dispersion to
multiple fires caused by escaping natural gas or
electrical transmission equipment damaged by earthquake.
3. The topographic and related conditions within specified
areas of the City of Danville are such that:
- Extensive fire damage may occur to multiple fires
involving untreated wood shake or shingle roofing and
building exteriors ignited because of exposure to fires
involving other buildings or dry vegetation within close
proximity but not readily accessible because of terrain.
- Extensive fire damage may occur due to the inability of
the fire district to gain sufficient access to fires
involving untreated wood shake or shingle roofing and
building exteriors due to terrain, slopes, landscaping,
fences, electrical transmission lines and other buildings.
