BACKGROUND:
November 17, 2015 Board of Supervisors Meeting
At the November 17, 2015 Board of Supervisors meeting, staff provided additional information on the proposed
Electric Vehicle Charging Station ("EVCS") requirements for non-residential development. Based on that
information, the Board approved exempting small commercial development projects with 10 or fewer off-street
parking spaces from the requirements of the ordinance, as recommended by staff.
As required by State Code, staff prepared local findings (Exhibit A) the Board must adopt to justify establishment
of building standards that are more restrictive than those in the 2013 Building Standards Code.
November 3, 2015 Board of Supervisors Meeting Follow-up
At the November 3, 2015 Board of Supervisors meeting, staff was given direction to provide additional
background and justification for the proposed EVCS requirements for non-residential development and consider
exempting small commercial developments. The basis for exempting small commercial projects is both the
economic impact on projects and a presumption that such projects may have shorter duration parking needs.
Research of the County's Land Use Permit and Development Plan applications approved or submitted since 2012
showed off-street parking for small commercial businesses varied from 0 to 12 off-street parking spaces. One
project with 0 off-street parking spaces was granted a variance for off-street parking. These projects average 8
off-street parking spaces. Removing the project granted a variance, the average number of off-street parking
spaces among these small commercial projects is 10. Based on this analysis, exempting projects with 10 or fewer
off-street parking spaces would be reasonable. Staff recommends exempting proposed projects with 10 or fewer
off-street parking spaces from the requirement to provide EVCS. Duration of typical parking need is not
information that is required for proposed projects and was not discernible among the projects that were surveyed.
In addition, duration of parking need would change over time for each individual property because different
tenants may have different parking needs, which would make EV parking regulations difficult to enforce.
Therefore, it would be difficult for the County to base EV charging requirements on duration of parking need.
For commercial projects with more than 10 off-street parking spaces, the proposed EV charging requirements
would be based on the California Green Building Code Standards Tier 2 Non-Residential Voluntary Measures,
which are measures above the State's minimum requirements that local jurisdictions can adopt voluntarily. The
Tier 2 Non-Residential Voluntary Measures were developed by the California Building Standards Commission
through a collaborative process that included input from stakeholders in the building industry, local jurisdictions
throughout the State, as well as various State departments.
November 3, 2015 Board of Supervisors Staff Report
In May 2015, following a referral from the Board of Supervisors on March 31, 2015, Department of Conservation
and Development (“DCD”) staff presented to the Ad Hoc Committee on Sustainability (“Committee”)1 the new
residential and non-residential 2013 California Green Building Standards Code requirements for electric vehicle
supply equipment (“EVSE”), which became effective statewide on July 1, 2015. The Committee provided
direction to staff for developing local amendments to the 2013 California Green Building Standards Code for
County adoption.
At the September 14, 2015 Committee meeting, the Committee required potential amendments, directed staff to
draft additional amendments, and approved a recommendation to the Board of Supervisors on the matter. The
proposed changes to the state-wide requirements are summarized as follows:
Changes for new multi-family buildings:
Increase the required number of EVCS to five percent of the total number of parking spaces provided, where
three percent is the minimum required in the State Code;
Require a minimum of one EVCS for every new multi-family building (three or more units) as opposed to
State Code which requires no EVCS for multi-family buildings with fewer than 17 units;
Require that EVSE be installed for each EVCS in addition to the electrical infrastructure required by the
State Code.
Changes for new non-residential buildings:
Increase the required number of EVCS to six percent of total number of parking spaces provided, where
three percent is the minimum required in the State Code;
Required number of EVCS in new construction shall provide fully operational EVSE as opposed to State
Code which requires electrical infrastructure only;
Require a minimum of one EVCS for every parking area associated with a new commercial building as
opposed to State Code which requires no EVCS for parking areas of 50 or fewer parking spaces. (Proposed
projects with 10 or fewer off-street parking spaces are exempt from the requirement to provide EVCS)
County Counsel reviewed DCD’s draft and prepared a final ordinance to amend the 2013 California Green
Building Code Standards Code to establish electric vehicle parking and charging station standards. The final draft
is attached (Exhibit B).
After the ordinance is adopted, County Counsel will send a final version of the ordinance to the Office of the
Clerk of the Board to arrange for publication in the Contra Costa Times with the names of the supervisors voting
for and against it. This must occur within 15 days of adoption. The ordinance will be effective 30 days after it is
adopted.
1 The Ad Hoc Committee on Sustainability is composed of Supervisors John Gioia and Federal D. Glover. Note
that Supervisor Glover was not in attendance at the March-September meetings.
CONSEQUENCE OF NEGATIVE ACTION:
Without adopting the proposed local amendments, the County will continue to adhere to the State mandatory
standards for electric vehicle infrastructure.
CLERK'S ADDENDUM
CLOSED the hearing; and ADOPTED Ordinance No. 2015-22, amending the 2013 California Green Building
Standards Code to establish electric vehicle parking and charging station standards.

CONTRA COSTA COUNTY
FINDINGS IN SUPPORT OF CHANGES, ADDITIONS, AND DELETIONS TO
STATEWIDE BUILDING STANDARDS CODE
The California Building Standards Commission has adopted and published the 2013 Building
Standards Code, which is comprised of the 2013 California Building, Residential, Green
Building Standards, Electrical, Plumbing, and Mechanical codes. These codes are enforced in
Contra Costa County by the Building Inspection Division of the Department of Conservation and
Development.
Although these codes apply statewide, Health and Safety Code sections 17958.5 and 18941.5
authorize a local jurisdiction to modify or change these codes and establish more restrictive
building standards if the jurisdiction finds that the modifications and changes are reasonably
necessary because of local climatic, geological or topographical conditions.
Ordinance No. 2015-22 adopts the statewide codes and amends them to address local conditions.
Pursuant to Health and Safety Code section 17958.7, the Contra Costa County Board of
Supervisors finds that the more restrictive standards contained in Ordinance No. 2015-22 are
reasonably necessary because of the local climatic, geological, and topographic conditions that
are described below.
I. Local Conditions
A. Geological and Topographic
1. Seismicity
(a) Conditions
Contra Costa County is located in Seismic Design Categories D and E, which
is the worst earthquake area in the United States. Buildings and other
structures in these zones can experience major seismic damage. Contra Costa
County is in close proximity to numerous earthquake faults including the San
Andreas Fault and contains all or portions of the Hayward, Calaveras,
Concord, Antioch, Mt. Diablo, and other lesser faults. A 4.1 earthquake with
its epicenter in Concord occurred in 1958, and a 5.4 earthquake with its
epicenter also in Concord occurred in 1955. The Concord and Antioch faults
have a potential for a Richter 6 earthquake and the Hayward and Calaveras
faults have the potential for a Richter 7 earthquake. Minor tremblers from
seismic activity are not uncommon in the area.
Contra Costa County Findings
2
A study released in 1990 by the United States Geological Survey says that
there is a 67% chance of another earthquake the size of Loma Prieta during
the next 30 years, and that the quake could strike at any time, including today.
Scientists, therefore, believe that an earthquake of a magnitude 7 or larger is
now twice as likely to happen as to not happen.
Interstates 680, 80, 580 and State Route 4 run the length throughout Contra
Costa County. These interstates and state routes divide the County into a west,
south, north and east. An overpass or undercrossing collapse would
significantly alter the response route and time for responding emergency
equipment. This is due to limited crossings of the interstate and that in some
areas there is only one surface street, which runs parallel to the interstate,
which would be congested during a significant emergency.
Earthquakes of the magnitude experienced locally can cause major damage to
electrical transmission facilities and to gas and electrical lines in buildings,
which in turn start fires throughout the County. The occurrence of multiple
fires will quickly deplete existing fire department resources; thereby reducing
and/or delaying their response to any given fire.
(b) Impact
More restrictive electric vehicle charging standards would not negatively
impact the County’s infrastructure or public safety resources in the event of a
major earthquake.
2. Soils
(a) Conditions
The area is replete with various soils, which are unstable, clay loam and
alluvial fans being predominant. These soil conditions are moderately to
severely prone to swelling and shrinking, are plastic, and tend to liquefy.
Throughout Contra Costa County, the topography and development growth
has created a network of older, narrow roads. These roads vary from gravel to
asphalt surface and vary in percent of slope, many exceeding twenty (20)
percent. Several of these roads extend up through the winding passageways in
the hills providing access to remote, affluent housing subdivisions. The
Contra Costa County Findings
3
majority of these roads are private with no established maintenance program.
During inclement weather, these roads are subject to rock and mudslides, as
well as down trees, obstructing all vehicle traffic. It is anticipated that during
an earthquake, several of these roads would be unpassable so as to prevent fire
protection resources from reaching fires cause by gas line ruptures or other
sources.
3. Topographic
(a) Conditions
i. Vegetation
Highly combustible dry grass, weeds, and brush are common in the hilly
and open space areas adjacent to built-up locations six (6) to eight (8)
months of each year. Many of these areas frequently experience wildland
fires, which threaten nearby buildings, particularly those with wood roofs,
or sidings. This condition can be found throughout Contra Costa County,
especially in those developed and developing areas of the County.
Earthquake gas fires due to gas line ruptures can ignite grasslands and
stress fire district resources.
ii. Surface Features
The arrangement and location of natural and manmade surface features,
including hills, creeks, canals, freeways, housing tracts, commercial
development, fire stations, streets and roads, combine to limit feasible
response routes for Fire District resources in and to District areas.
iii. Buildings, Landscaping and Terrain
Many of the newer large buildings and building complexes have building
access and landscaping features and designs, which preclude or greatly
limit any approach or operational access to them by Fire District vehicles.
In addition, the presence of security gates and roads of inadequate width
and grades that are too steep for Fire District vehicles adversely affect fire
suppression efforts.
When Fire District vehicles cannot gain access to buildings involved with
fire, the potential for complete loss is realized. Difficulty reaching a fire
Contra Costa County Findings
4
site often requires that fire personnel both in numbers and in stamina.
Access problems often result in severely delaying, misdirecting or making
impossible fire and smoke control efforts. In existing structures where
pitch roofs have been built over an existing roof, smoke detectors should
be required to warm residents of smoke and fire before the arrival of fire
personnel.
(b) Impact
More restrictive electric vehicle charging standards would not impact the
availability of the County’s fire or public safety resources.
B. Climatic
1. Greenhouse Gas Emissions
(a) Conditions
The California Air Resources Board has collected information on emissions
from air pollution sources since 1969. This information is periodically
compiled by State and local air pollution control agencies to create an
emission inventory. The California emission inventory maintains information
on various air pollution sources and identifies “mobile sources” (all on-road
vehicles such as automobiles and trucks; off-road vehicles such as trains,
ships, aircraft; and farm equipment) as a primary pollution source. California
adopted land use and transportation policies that intend to help reduce
greenhouse gas emissions by promoting the use of renewable energy sources.
(b) Impact
More restrictive electric vehicle charging standards would follow the intent of
State legislation to aggressively implement energy policies designed to ensure
success in meeting their greenhouse gas emission reduction and reusable
energy goals.
2. Temperature
(a) Conditions
Contra Costa County Findings
5
Temperatures have been recorded as high as 114° F. Average summer Contra
Costa County Findings 5 highs are in the 75° to 90° range, with average
maximums of 105° F in some areas of unincorporated Contra Costa County.
(b) Impact
More restrictive electric vehicle charging standards would not have a negative
impact on the temperature conditions within the County.
3. Winds
(a) Conditions
Prevailing winds in many parts of Contra Costa County are from the north or
northwest in the afternoons. However, winds are experienced from virtually
every direction at one time or another. Velocities can reach fourteen (14) mph
to twenty-three (23) mph ranges, gusting to twenty-five (25) to thirty-five (35)
mph. Forty ( 40) mph winds are experienced occasionally and winds up to
fifty-five (55) mph have been registered locally. During the winter half of the
year, strong, dry, gusty winds from the north move through the area for
several days creating extremely dry conditions.
(b) Impact
More restrictive electric vehicle charging standards would not have a negative
impact on the wind conditions within the County.
II. Necessity of More Restrictive Standards
Because of the implementation of more restrictive electric vehicle charging standards
would not have a negative impact on the conditions described above, and is consistent
with State land use and transportation policies intended to help reduce greenhouse gas
emissions, the Contra Costa County Board of Supervisors finds that the increased electric
vehicle charging standards set forth in Ordinance No. 2015-22 are reasonable and
justified. The ordinance amends the statewide codes by requiring the following:
New multi-family buildings:
Contra Costa County Findings
6
Increase the required number of Electric Vehicle Charging Stations (“EVCS”) to five
percent of the total number of parking spaces provided, where three percent is the
minimum required in the State Code;
Require a minimum of one EVCS for every new multi-family building (three or more
units) as opposed to State Code which requires no EVCS for multi-family buildings
with fewer than 17 units;
Require that Electric Vehicle Supply Equipment (“EVSE”) be installed for each
EVCS in addition to the electrical infrastructure required by the State Code.
Changes for new non-residential buildings:
Increase the required number of EVCS to six percent of total number of parking
spaces provided, where three percent is the minimum required in the State Code;
Required number of EVCS in new construction shall provide fully operational EVSE
as opposed to State Code which requires electrical infrastructure only;
Require a minimum of one EVCS for every parking area associated with a new
commercial building as opposed to State Code which requires no EVCS for parking
areas of 50 or fewer parking spaces. (Proposed projects with 10 or fewer off-street
parking spaces are exempt from the requirement to provide EVCS)
