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 January and March, 1995 and in 1998 and 2006.
Relative Humidity: Humidity generally ranges from fifty percent (50 %) 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 rnph, 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 methodsfrnaterials 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
enviromnents 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 and 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
The relatively young geological processes that have created the San Francisco Bay Area are
still active 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 high -to- moderate seismic hazard zones.

Many of the soils found throughout the City of Petaluma are highly 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 1I (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 adopted by the City Council..
Section 17.24 of the Petaluma Municipal Code has been amended to clarifyconflicting
language.
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 drownings thus
requiring the need to have taller swimming pool barriers.
CONCLUSION
The local climactic and geological conditions have necessitated these minor modifications
to the Title 24 California Building Standards Codes.
