FINDINGS
AMENDMENTS - UNIFORM BUILDING CODE
SECTION FINDINGS:
504(d) 1. Whereas the UBC.does.not provide for common walls astraddle of
property lines and in omitting such provisions, the UBC prevents
the concept of row houses with individual ownership, thereby in-
creasing the cost of residential construction; it is, hereby,
found that such common wall.construction is an acceptable alternate
to individual wall construction at property lines and further such
construction provides equal structural and fire safety when con-
structed as set forth in this amendment and, further, such
construction will contribute to lowering the costs of residential
construction; and
504(e) 2. Whereas the UBC does not allow openings in exterior.walls of buildings
constructed near or adjacent to property lines, and where adjacent
lots with buildings thereon are often owned by the same person or
persons, and where the buildings are often near or adjacent to the
separating property line; it is hereby found that to permit full and
convenient.utilization of buildings by owners, openings should be
permitted in exterior walls of buildings near or adjacent to property
lines when protected.by fire assemblies installed in each opening in
each building and such openings are properly closed when the same
owner or owners no longer own both adjacent properties; and
2903(a) 3. Whereas the UBC does not set forth the kinds of information to be
provided in a report of.fill.and compaction; it is hereby found that
to provide the Building Official with a properly certified, compre-
hensive fill and /or compaction report, and to prevent arbitrary and
capricious demands by the Building Official it is necessary to list
the specific information to be shown on certified fill and /or com-
paction reports; and
2905(c) 4. Whereas the UBC sets forth minimal direction for information to be
included in soil investigation reports, and all soils investigation
agencies do not provide the same information; it is hereby found
that to provide specific direction to soils investigation agencies
on information to be provided and to provide uniformity in soils
reports and to provide adequate information to the Building Official
for proper evaluation of site development, it is necessary to
elaborate the requirements for soils reports; and
2905(f & g) 5. Whereas the City of San Luis Obispo is situated in a valley with roll-
ing hills, which presents unusual drainage problems, it is hereby
found necessary to establish areas for proper disposal of drainage
water; and
-1-
SECTION FINDINGS:
Table 29 -A 6. Whereas the City of San Luis Obispo is situated.on soils with highly
expansive characteristics, and .further, the rolling topography of
the land presents unique foundation problems; it is hereby found
that Table 29 -A, as.set forth in the UBC, does not adequately provide
for the.soil conditions.found . in San Luis Obispo, which makes it
necessary to adopt provisions..which take into account most of the
problems normally encountered when building conventionally built
buildings.in San Luis Obispo; and
3207(e) 7. Whereas the UBC permits, by an exception, residential roof drainage
water to drain across the-public sidewalk, and where this permission
increases the City's liability fron injuries due to falls; it is
hereby found that such drainage water carries mud, silt and sand
which is deposited on the public sdiewalk, creating a slippery
surface, hazardous to pedestrians and that such hazard can be mini-
mized by prohibiting drainage water to drain in a concentrated flow
across public sidewalks; and
3703(f) 8. Whereas it has been determined that the 3/4" mesh opening set forth
in the UBC is too large to property inhibit flying flaming brands
and the Uniform Fire Code permits only 1/2" mesh for incinerator
chimney spark arresters,.and that the UBC does not regulate or re-
quire-spark arresters.-on fireplace chimneys; it is hereby found that
fireplaces present the same flying flaming brand hazards as do incin-
erators and consistency with the UFC is essential for uniform enforce-
ment, the 1/2" mesh opening shall apply to both fireplace and inciner-
ator chimneys; and
4409 9. Whereas the UBC makes no provisions for control of dust generated
by demolition operations, and airborne dust presents a definite
health hazard; it is hereby found that wetting down demolition debris
minimizes the health hazards to persons working and`frequenting an
area where demolition operations are taking place; and
5406(a) 10.. Whereas the provisions of Section 5406 in the UBC has.been preempted
by the Federal Government; it is hereby Eound to be necessary to
include the requirements of the U.S. Consumer Product Safety Standard
as part of the Code.requirements for protection of health, safety
and welfare; and
5301(b) 11. Whereas the State of California has mandated compliance with energy
UBC Appendix conservation standards equal to.those of the State of California;
it is hereby found to be most convenient and uniform to adopt those
standards published by the State of California; and
Chapter 12. Whereas the Building Official does not enforce excavating and grading
70, and further the topography and soils in San -.Luis Obispo create unique
UBC Appendix development problems and further, the City has seen fit to write its own
excavation-and grading ordinance.; it is hereby found.to.be necessary,
to avoid conflict and confusion, to delete all of Chapter 70 of the UBC
from the Building Regulations of the City of San Luis Obispo; and
-2-
AMENDMENTS - UNIFORM MECHANICAL CODE
SECTION FINDINGS
1901(c) 1. Whereas the Uniform Mechanical Code makes no provision for exhausting
objectionable odors..and smoke.generated by.cooking activities in
residences,-and further such smoke.tends to trip smoke alarms, causing
eventual removal..or deactivation of such.alarms, creating a hazardous
situation; it is hereby found that exhausting cooking odors and
smoke, at the source, will decrease false alarms, discourage deacti-
vation of smoke alarms and improve safety and welfare in the home; and
AMENDMENTS - UNIFORM PLUMBING CODE
201(k) 1. Whereas the Uniform Plumbing Code lists an outdated reference
standard for establishing wall thickness minimums for ABS pipe
and fittings; it is hereby found that to take advantage of the
most recent information available on controversial products, which
will keep construction costs reasonable and at the same time, provide
the homeowner with trouble free service, it is necessary to adopt
the most recent ASTM Standard; and
315(f) 2. Whereas the Uniform,Plumbing Code does not address.the problem of
penetrations of fire- resistive membranes: by plastic pipe and where
this problem is addressed in the State Building Standards; it is
hereby found that to inform persons of the need -for maintaining
fire - resistive integrity,.this amendment is necessary; and
317 3. Whereas the general soil profile.and soil composition within the City
of San Luis Obispo does not adequately provide a. uniform levelling
bed, and are not generally suitable for initial backfill around sewer
pipe; it is hereby found to.be necessary to provide a sand.bed and
backfill.for ease of alignment- and.pipe protection; and
401(a) 4. Whereas the Uniform Plumbing-Code presently limits the use of plastic
503(a) DMV to-residential buildings not over two stories in height and where
the State Building Standards permit it to be used in residential
buildings of any height; it is hereby found that to be consistent
with State Law, this amendment is necessary; and
401(a) 5. Whereas-bituminous fiber pipe.is listed in the Uniform Plumbing Code
as an approved sewer pipe and whereas it has prcven to be unsatis-
factory when installed in highly expansive and poor leveling soils;
it is hereby found that due-to the - detrimental effect of the clay
soils existing in San Luis Obispo,'it is necessary to prohibit the
use of bituminous fiber pipe for building drain and sewer pipe.
