EXHIBIT"A"
CLIMACTIC
Precipitation: Precipitation ranges from twenty inches (20") to approximately,twenty-five inches
(25") per year. Approximately ninety percent (90%) falls during the months of November
through April, and ten percent (10%) from May through October. Severe flooding occurred
during the'months of Januaryand March, 1995 and in 1998 and 2006.
Relative Humidity: Humidity generally ranges from fifty percent (5,0%) during daytime and
eighty-six percent (86%) at night. It drops to twenty-percent (20%) during the summer months
and occasionally drops lower during the months of September through November.
Temperatures: Temperatures have been recorded as high as 104 degrees Fahrenheit. Average
summer:highs are in the 78-85 degree range.
Winds: Prevailing winds are from the northwest. However, winds are,experienced from virtually
every direction at one time,or another. Velocities are generally in the 5-15 mph range, gusting to
7.4-30 mph, particularly during the summer months. Extreme winds, up to 50 mph, have been
known to occur.
Soils: Much of Petaluma has "Adobe" type soil. This soil has very high clay content and is
extremely expansive. With Petaluma's dry summers and wet Winters the moisture content of the
soil varies greatly during the course of the year. This .moisture content change causes
expansion/contraction of the clay soil. This expansion/contraction can place significant loads on
concrete slabs and foundation systems making some, "standard" foundation methods/materials
inappropriate.for the local conditions encountered.
TOPOGRAPHIC
The topographic environment,of a community is primarily a combination of two (2) factors: the
area's, physical geographic characteristics and the historic pattern of urban-suburban
development. These two (2)' factors, alone and combined, create a mixture of environments
which ultimately:determine the needs,of the City of Petaluma's Building:regulations.
The basic:geographical boundaries of the city include hills to the south and west, and valley floor
in the central area a nd to the north and east. The Petaluma River bisects the city through the
central. area The City of Petaluma covers 13 square miles, including an urban population
estimated at 58,000. The city's service:area is a conglomeration of bay, plains, hills, valleys, and
ridges.
GEOLOGICAL
y young-geological i p y Area are still
The7elafivel rocessesthat have created the San Bay
today. Two (2) active earthquake faults (San Andreas and the Hayward-Rodgers Creek)
affect the Petaluma area. Approximately fifty percent (50%) of the city's land surface is in the
Exhibit A to Ordinance
Page I
16
high-to-moderate seismic,hazard zones.
Many of the soils'found throughout the City:of Petalumaarehighly expansive adobe type soils.
The combination the highly expansive nature of these 'soils along with the long dry 'summers
followed by a compressed rainy season create high stresses on building foundation systems, as
such some simpler types of foundation systems are not adequate for these soils conditions.
As there are no "isolated, self contained" areas within City limits the Grading Permit exception
J103.2 (1) was removed for clarity.
PROCEDURAL CLARIFICATION
Changes to the,Stop•Work Order section are made to more clearly'explain the Stop Work Order
process and to establish the penalties for violations of this section.
DEFINITION CLARIFICATION
Due to code enforcement problems in the past, the description of buildings not requiring permits
was expanded to help clarify when permits are/are not required.
CONTINUITY
All the amendments to Chapters 7 and 9 of Part II (Building Code) of the California Building
Standards Codes contained in this Ordinance are made so that they reflect amendments to
chapters 7 and 9 of Part 9 (Fire,Code) of the California Building Standards Code made through a
separate Ordinance by the Fire Marshal's Office:
SUMMARY
These local climatic conditions,affect the pressures applied,to concrete flatwork and foundations
beyond the.,strength of welded wire fabric reinforcement material.
The population and housing ;density increased the dangers of accidental drowning's thus
requiring the need'to have taller swimming pool barriers.
CONCLUSION
The local climacticand,geol:ogical conditions have necessitated these minor modifications to the
Title 24 California Building Standards Codes.

REACO
REDWOOD EMPIRE ASSOCIATION OF CODE OFFICIALS
1007B WEST'COLLEGE AVE. BOX,326
SANTA ROSA, CA 95401
DATE: October, 2013
TO: All REACO Members and Interested Stakeholders
RE: Recommendations for amendment options in adoption of
California,Green Building Code Standards (CALGreen)
The mission of the Redwood Empire Association of Code Officials (REACO) is to
promote life safety and the protection of property through the development,
interpretation and application of'consistent building codes, standards and policies.
The model code adoption cyclefor the 2013 codes presents a unique opportunity for our organization to
provide our members and the public;with recommendations,for'a consistent and effective regional
sustainable building program. Duringthe:2010 model code update,REACO recommended all
jurisdictions amend the California Green Building Standards Code (CALGreen) to.include Tier 1 levels
for both residential and nonresidential,occupancies. For the 2013 model code update CALGreen is
again composed of both.mandatory measures and appendices with two;tiers'of voluntary measures for
both residential and nonresidential new buildings. Selected portions-of the appendices may be adopted
by local ordinance amending CALGreen. The 2013 CALGreen code scope of projects that apply has
been increased to include residential alterations and additions,that increase either volume or area of a
dwelling. The scope of nonresidential projects for additions and alterations has also:been increased to
include additions of 1,000 square feet or more and alterations of$200,000 valuation or higher.
Tier 1 requirements for energy efficiency include a 15% increase in the minimum standards
established'by:;the California Energy Commission (CEC). Local jurisdictions are required to
receive approval from the'California.Energy,Commission for any ordinance that establishes
energy'efficiencystandardsiata higher level than the minimum standards set by the CEC.
The approval.,requires,a cost;effectiveness study to be completed. At this time, due to the
lag in approval by the CEC performance computer programs, there have been no cost
effectiveness-studies completed. The California Building Officials (CALBO) have
communicated to our membership the recommendationthat jurisdictions thaiwish to amend
CALGreen to Tier to not includethe enhancement amendment to energyefficiency
standards. Also, according to the CEC Blueprint newsletter of June, 2012, "a newly
constructed residential building built to the prescriptive requirements ofthe:2013 Standards
will use 25% less energy for lighting, heating, cooling;:ventilation, and water heating that one
built to the prescriptive requirements of the 2010 California Energy Code.: For nonresidential
buildings there will be-a 30% reduction. Tier 1 for energy efficiency increases the standards
an additional 15% thus making the cost?effectiveness,of such improvements more difficult to
achieve.
The Redwood Association of Code Officials surveyed membership and completed extensive
discussion of the alternate code adoption options. The recommendation was voted on by
membership on October 6, 2013, with direction to the executive board to draft a document
that all jurisdictions may use during their model code update ordinance process.
The.REDWOOD EMPIRE ASSOCIATON OF CODE OFFICIALS.Executive Board, as directed by the
membership, recommends,that local jurisdictions consider adoption of the Tier'1 voluntary
measures for both residential and',rionresidential projects for new buildings only and to include
the following categories within theTier'I measures: Planning &.Design, Water Efficiency &
Conservation, Material Conservation & Resource Efficiency, and Environmental Quality as
mandatory.The.Executive Board does not recommend the adoption of Appendix Sections A4.2.
and A5.2 (EnergyEfficiency)_as mandatory to comply with compliance with:2013 CALGreen for
the reasons mentioned above.
Recognizing that these regulations will require additional training, the REACO Education Committee, in
conjunction with the North Coast'Builder's.Exchange (NCBE), the American Institute of Architects
Redwood Empire Chapter (AIARE), and the Redwood Empire.Chapter of the USGBC is scheduling a
series•of;training opportunities`locally. Our,goal is to provide consistent training in the application of the
standards to both the enforcement and building industry:
