resistive construction without openings. Buildings required to have automatic fire-
sprinkler protection as set forth in Section 13113 of the Health and Safety Code are
prohibited from using area separation walls in lieu of automatic fire-sprinkler protection.
FINDING:
This modification is necessary because the City of Dublin has a dry period of
at least five months each year. Additionally, the area is subject to occasional
drought and because of dryne.s.s., a raoidlv burnin~ urass fire or exterior
building fire can quickly transfer to other buildings. These modifications are
consistent with the Fire Authority having jurisdiction.

this Section shall not be allowed unless or until the owner of the required yard shall file
an agreement binding such owner, his heirs, and assignees, to set aside the required yard
as unobstructed space having no improvements. Such agreement shall be recorded in the
Alameda County Recorder's Office.
FINDING:
This modification is necessary because the City of Dublin has a dry period of
at least five months each year. Additionally~ the areais subiect to occasional
drought and because of dr.vness, a raoidly burninll grass fire or exterior

City of Dublin is located in a highly active Seismic Zone 4. Nonmetallic-
sheathed cable is not afforded the same protection from damage as wirine
raceways and damage to nonmetallic-sheathed cable could occur in a seismic
event, thereby increasin~ the ootential for a fire. ·
Section 7.40.070 DMC Section 609.3, Chapter 6 UPC, Water piping in slab floors--
Amended.
Section 609.3, first paragraph, is amended by replacing it to read:
Section 609.3 Water piping shall not be installed in or under a concrete floor slab within a
building without prior approval of the Building Official. When approved; such piping shall be
installed in accordance with the following requirements:
FINDING:
This section eliminates water piping in or under concrete floor slabs within a
building. This amendment is necessary for the following reasons:
Most of the surface soils in the City of Dublin are relatively voun~ and
unconsolidated sedimentary materials formed from a wide variety o(.parent
materials. The varying chemical com. p.psitjon, degree of weathering and the
relatively acid environment have created soils of varying types, which are
particularly corrosive in nature.
Much of the surface soil in the city of Dublin is highly....expansive (!;e.~ shrink-swell
behavior) and has low bearing strength.
There are two .tx. pes of expansive soils in the area:
a. the organic silty clays which are the recent bay muds; and
b. the plastic silty c!..a..y.s which weather from the shale found in the
hills surrounding th_e..City of Dublin
Page 37 of 39
The local climate is characterized,bx, markedly delineated rainy and dry seasons~
which tend to maximize the expansive characteristics of soil.
4. Some parts of the City of Dublin have hard water~ whi. c_.h is,,,corrosive to ferrous
pipe.
The ~roundwater table is unusually high in many places.
The City of Dublin is a highly active seismic area.
Section 7.40.080 DMC Section 701.1, Chapter 7 UPC, Materials--Amended.

exceeding two (2) stories in height and to relocatable public school buildings. For the purpose of
this subsections, the first floor ora building shall be that floor that has fifty (50) 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 habitation and used only for vehicle parking, storage,
or similar use shall be permitted.
FINDING:
This section limits the use of pl. astic piping to residential buildings 2 stories in
height or less. This amendment is necessary for the following reasons:
Much of the surface soil in the city of Dublin is highly expansive (i.e. shrink-swell
behavior) and has low bearin~ streneth.
There are two tyoes of exoansive soils in the area:
(a) the organic silty clays which are the recent bay muds; and
(b) the olastic silty clays which weather from the shale found in
the hills surrounding the Ci.ty of Dublin
The local climate is characterized by markedly delineated rainy and dry seasons~
which tend to maximize the expansive characteristics of soil.
3. The City of Dublin is a highly active seismic area.
Section 7.40.090 DMC Section 903.1, Chapter 9 UPC, Materials--Amended.
Section 903.1 is amended by replacing subsection 903.1.2 to read:
903.1.2 ABS and PVC DWV piping installations shall be limited to residential construction not
exceeding two (2) stories in height and to relocatable public school buildings. For the purpose of
this subsections, the first floor of a building shall be that floor that has fifty (50) 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 habitation and used only for vehicle parking, storage,
or similar use shall be permitted.

This section limits the use of plastic piping to residential buildings 2 stories in
height or less. This amendment is necessary for the following reasons:
Much of the surface soil in the ci~....o.f Dublin is highly expansive (i.e., shrink-swell
behavior) and has low bearing strength.
There are two types of expansive soils in the area:
(a) the organic sil .ty clays which are the recent bay muds; and
