GAS-POWERED LEAF BLOWER BAN ENFORCEMENT - ONE YEAR
STATUS REPORT
This is an informational report and no Council action is needed at this time.
BACKGROUND
On May 1, 2000, the City Council banned the use of gas-powered leaf blowers in residential areas
effective July 1, 2002. On May 20, 2002, the City Council continued the effective date of the ban to
July 1, 2005. The three-year deferment was to allow leaf blower manufacturers time to develop
alternatives to combustion-powered leaf blowers (CMR:265:02). At its June 13, 2005 meeting, Council
adopted the ban and requested that staff return after a year with a status report on the ban.
DISCUSSION
Enforcement Process - Prior to the July 1, 2005 effective date of the ban, staff indicated that due to
limited staffing resources only one Community Service Officer (CSO) would handle leaf blower and
other noise issues (CMR:281:05). Staff indicated enforcement would be done on a complaint basis.
After the ban became effective, staff noticed that some residents were using the ordinance to deal with
other issues. As an example, one person called in to report a violation of the leaf blower ordinance.
The CSO investigated and determined that the alleged violator did not have a gardener, did not own a
leaf blower, and that there were some other unresolved neighbor issues. As a result, staff decided that
prior to any enforcement action, three calls from different reporting parties would be required prior to
the CSO taking enforcement action.
Reporting parties are asked to provide the date, time and location of the violation, as well as a
description and license plate of any associated vehicles. Additionally, reporting parties need to provide
information regarding the type of equipment being used. The CSO receives the report and processes a
warning or administrative citation as appropriate.. Individuals or businesses receive two warnings before
an administrative citation is issued. Warning letters are mailed to homeowners and gardening services
CMR:320:06 Page 1 of 4
when a professional gardening service is identified as the violator. This process allows homeowners the
opportunity to correct the violation with their gardeners before a citation is issued.
In some instances, reporting parties are unable or unwilling to provide specific information about a
suspected violation. The CSO schedules time to investigate these complaints by checldng the location
on the time and day of week that was reported to determine whether there is a violation. The CSO does
spend some limited time in the field conducting pro-active leaf blower enforcement as workload and
other duties allow.
Previously, complaints were tracked by location, limiting the Department’ s ability to properly identify
and warn violators in a timely manner. The CSO now records all complaints received into a special
database. License plate information affords access to addresses and company names which are cross-
referenced in the database. This tracking system allows the CSO to identify repeat offenders in the case
of professionals who move from one location to another. Thus, a professional gardening company may
generate two complaints at two different locations resulting in a final warning or citation being issued.
The City Website provides information and reporting options, allowing both telephone and Internet
access to report violations directly to the CSO.
The CSO devotes three to five hours a day to administrative duties associated with leaf blower and other
noise complaints and approximately two hours per day to field work related to noise investigations.
With the prohibition of gas-powered blowers in residential areas, staff is no longer issuing permits as
originally regulated by the original ordinance. The CSO is also responsible for abandoned bicycle
abatement, noise exception permits and temporary parking issues. Attachment One provides a
comparison of the number of complaints between FY 2004/05 and 2005/06.
The administrative fine for each citation issued is one hundred dollars. Currently the fine does not
increase with subsequent violations. Staff will be monitoring repeat offenders to determine if a
progressive increase in fines would be warranted.
Impact on Gardening Businesses - Staffhas heard from some gardeners and representatives from the
Bay Area Gardener’s Association (BAGA) that since the ban has been in effect they have had to raise
their rates, have lost clients, and have suffered significant economic losses. Staff requested specific
information from BAGA about these losses on several occasions, but as yet has not received any
specific information.
Many professional gardeners are employing gas-fueled generators to provide power for the electric leaf
blowers. These generators are usually worn as a backpack or are stationary. In some cases,
complainants have assumed that the backpack unit is a gas-powered leaf blower due to the noise that is
generated from the generators. Those complainants were informed of the difference and advised of the
lack of a violation. Ten complaints were received specific to the noise level associated with the gas-
powered generators. The CSO conducted decibel readings in each of these cases and found that the level
was just below 65 decibels and therefore in compliance with the ordinance.
CMR:320:06 Page 2 of 4
Impact on Cite/Operations - At the time the ban was implemented, the City Manager directed that the
use of gas-powered blowers by City staff and contractors in all areas was prohibited, even though
commercial zones are exempt.
Public Works and Community Services have indicated that their increase in expense was lower than
originally expected. The purchase of three generators and six electric blowers over the past year cost
$1,380. The electric blowers tend to fail after three months of use, necessitating their replacement
throughout the year at $80 per unit.
Staff has determined that electric blowers are not as efficient, thus increasing the time.needed to
accomplish their tasks. Rather than increase costs for contract services, frequency was reduced at
various sites from daily to three times per week.
TechnologyUpdate - Several manufacturers of gas-powered leaf blowers advertise that their equipment
meets or exceeds the California Air Resources Board standards for lower emissions. Manufacturer
information from Stihl, Husquvarna and others list the noise output for these newer models in the range
of 62 to 67 decibels per ANSI standards. The ANSI-attributed measurement is obtained at a distance of
50 feet. The Palo Alto Municipal Code prescribes that the measurement shall be obtained at a distance
of 25 feet. While staff has not taken sound meter readings of the new equipment, staff does believe that
measuring the decibel level at half the distance used by manufacturers will undoubtedly result in noise
levels that exceed the maximum limit of 65 decibels.
RESOURCE IMPACT
The cost associated with the CSO who handles leaf blower complaints is approximately $76,682. As
noted above, the City has expended approximately $1,380 for new equipment. To date, the City has
received $3,400 in revenue associated with administrative fines.

SUBJECT:REQUEST TO PROVIDE STAFF WITH POLICY DIRECTION FOR A
REVISED ORDINANCE REGULATING LEAF BLOWERS AND
APPROVAL OF AMENDMENT TO PALO ALTO MUNICIPALCODE
CHAPTER 9.10 EXTENDING THE CURRENT ORDINANCEUNTIL
DECEMBER 31, 2005
REPORT IN.BRIEF
In 2002, the City Council amended Chapter 9.10 of the Palo Alto Municipal Code regulating leaf
blowers to defer the prohibition of the use of combustion-fueled leaf blowers in residential areas
from July 1, 2002 to July 1, 2005. There are a wide variety of opinions and perspectives on the
issue that involve not only environmental concerns but those of economics and social justice as
well. Because of the complexity of the issues, this report provides a list of options for the Council
to consider regarding the regulation of leaf blowers, an update on other cities’ experiences,
technology, and cost implications. Staff is reconm~ending a continuation of the current ordinance
until December 31, 2005, to provide additional time to get public feedback and to draft any
potential revisions to the ordinance.
CMR:281:05 Page 1 of 13
RECOMMENDATION
Staff requests Council policy direction on a revised ordinance and recommends that the city
Council approve the attached amendment to Chapter 9.10 of the Palo Alto Municipal Code
regulating combustion-fueled leaf blowers by extending the current ordinance until December 31,
2005.
BACKGROUND
In 1972, the City established noise standards with the adoption~ of Palo Alto Muni.cipal Code
Chapter 9.10. In 1986, as a result of numerous complaints about noise from equipment used by
gardeners and City employees and contractors, the Police Department started to formalize its
response and enforcement of the ordinance. At that time, after conducting noise meter readings on
18 different pieces of commonly used equipment, it was concluded that the noise ordinance was
restrictive and needed to be reviewed for changes. In 1987, staff presented three options to Council
specificaily related to leaf blowers, including:. 1) a ban on the use of gasoline-powered leaf blowers,
2) a prohibition on the use of gasoline leaf blowers within 250 feet of a single family residence, and
3) a prohibition on the use of a gasoline leaf blower exceeding 90 dBAs at a distance of 25 feet
between 10:00 a.m. and 4:00 p.m. Monday through. Saturday, and total prohibition on Sundays and
holidays. The Council approved the third option with the following modifications: 82 dBAs and a
further reduction to 75 dBAs after July 1, 1989, with a restriction in hours from 9:00 a.m. to 5:00
p.m. Monday through Saturday, and from 10:00 a.m. to 4:00 p.m. on Sundays and holidays.
In 1998, Council directed staff to again identify and evaluate options for addressing leaf blower
noise; to review environmental issues; to provide a survey of what other jurisdictions had done
regarding leaf blowers; and to provide information about the current level of enforcement and on
issues related to enforcement of any proposed ordinance changes.
The following year, staff provided a list of recommendations (CMR:352:99) regarding the
regulations of leaf blowers to the Policy and Services Committee. At that time, Committee
members asked that staff develop an alternative to the City issuing permits; review the hours of use
around hotels; review the hours City crews use blowers around residences; work with Bay Area
Gardeners Association (BAGA) in certification and training efforts:, and reconsider the hours for use
by homeowners.
As a result, the City Council adopted a revision to the leaf blower ordinance (CMR:202:00) in 2000.
A portion of the ordinance that became effective on January 1, 2001 required that all commercial
operators be trained and certified on the ordinance and proper use of leaf blowers. Additionally, the
ordinance allowed the use of only City-approved leaf blowers. A secondary provision of the
ordinance, which was to take effect on July 1, 2002, would have prohibited the use of combustion-
powered leaf blowers. Use of fuel-powered leaf blowers by any person, including residents, would
CMR:281:05 Page 2 of 13
have been prohibited in residential areas after July 1, 2002. Finally, City crews would be prohibited
from using fuel-powered leaf blowers in residential areas.
In 2002, .the City Council again amended Chapter 9110 of the Palo Alto Municipal Code, deferring
the prohibition of the use of combustion-fueled blowers in residential areas until July 1, 2005. The
amendment was based upon the belief that leaf blower manufacturers would be able to enhance
technology enough to reduce the issues of noise generation and gas emissions during that time
period, would potentially develop a battery-powered blower that would meet the needs of
commercial gardeners and that the prohibition of leaf blowers in residential areas would result in a
substantial financial impact on the City’s Community Services andPublic Works Departments.
The current ordinance is due to sunset on July 1, 2005. At that time, .unless Council directs
otherwise, the use of gas-powered leaf blowers in residential areas by any person, (commercial
gardeners, City staff and crews, and residents) will be prohibited. Due to the complexities of the
issues, staff is requesting that the Council provide policy direction for a revised ordinance and in
order to allow for public discussion on the potential revisions, extending the current ordinance until
December 31, 2005.
DISCUSSION
Environmental Issues
There are three environmental issues associated with leaf blowers: noise levels; gas emissions and
particulate matter.
Gas Emissions - To date, most of the requirements have dealt with the reduction of gas emissions.
The Federal Environmental Protection Agency (EPA) Phase I and II standards basically require
manufacturers to build cleaner engines that will not degrade and release more emissions as they age.
Manufacturers are required to conduct in-house testing of engines to prove that the engine’s
performance meets the standards. In essence, EPA is encouraging engine manufacturers to design
new and improved uses of automotive-style overhead-valve (OHV) technology in non-hand-held
engines. EPA’s hope is toreduce emissions, as well as improve durability and fuel economy.
The California Air Resource Board (CARB) submitted a report in January 1999 to the State
Legislature that summarized the potentiai health and environmental impacts of leaf blowers and also
provide recommendations for alternatives to their use and/or development of additional standards to
which manufacturers are to adhere when developing new equipment. CARB recommended that
manufacturers develop technologies that would ultimately reduce the amount of fuel delivered to
the combustion Chamber for four and two stroke engines.
CMR:281:05 Page 3 of 13
CARB’s phased approach is a three-tier plan to reduce gas emissions from engines in the 20 to 50
cc displacement range. Tier I, which ran from 1995 to 1999, permitted 230 grams of emissions per
kilowatt. Tier II, which ran from 2000 until this year, reduced the grams per emission to 72. Tier
III, which started this year, requir.es emissions to be reduced to 50 g/Kwh. Attachment A lists those
manufactures that presently produce 2005 Tier III engines as listed by the CARB.
Particulate Matter - There has been a great deal of research done by the CARB and the American
Lung Association of California regarding the issue of particulate matter. Air pollution levels in
California have improved tremendously within the last few decades due to the aggressive controls
on vehicle industry and power tool manufacturers. However, CARB and the American Lung
Association believe Californians are still being exposed to a significant amount of particulate matter
from a wide variety sources.
CARB and the American Lung Association of California report particulate air pollution contributes
to cardiac illnesses, respiratory illnesses and cancer. The number of premature deaths linked to
particulate matter generated from a wide variety of sources are comparable to deaths from traffic
accidents and second-hand smoke. Hospital admissions, emergency room visits and asthma attacks
have increased over the years and population-based studies have linked particulate matter as the
cause. While particulate matter is still being researched, specific regulations and and/or
recommendations have not yet been developed by CARB or the EPA.
Noise - While the technology is slowly improving in this area, significant progress still remains to
be made. Over the last 20 years, noise levels of blowers have decreased from 90 decibels (dBA) to
today’s standard of 65 dBA. One manufacturer has developed a blower that is rated at 60 dBA.
In 2002, staff determined that the Los Angeles Department of Water and Power was aggressively
worked towards developing a portable electric leaf blower that would be suitable for use by
commercial gardeners. In 1998, they contracted with AeroVironment, Inc., which specializes in
new technology development, to assist in prototyping and designing a new leaf blower. Last
December, the Los Angeles Department of Water and Power contracted Giltronics Associates, Inc.,
to make the transition from prototype to mass production of leaf blowers.
The new leaf blower requires no power c6rd, weighs approximately 10 pounds less than a gas-
powered blower and is less than 65 dBA. According to the specifications, the energy source is a
nickel metal hydride battery pack that operates for approximately 45 minutes at 344 cubic feet per
minute. Currently, the Los Angeles Department of Water and Power has solicited interested
manufacturers through a "Request for Proposal" process, which ended April 22, 2005.
Battery-operated leaf blowers being produced by most manufacturers, however, have their own
problems associated with the handling and disposing of batteries, excessive weight, and poor
performance compared to gas-powered models. There are battery-operated hedge clippers and light
duty string trimmer models, and within five to ten years, technological advances may make this
CMR:281:05 Page 4 of 13
power source feasible for leaf blowers as well. Manufacturers have not yet developed a model that
is compatible for commercial use.
Staff has recently conducted some sound meter readings of Hasquavarne, Stihl, and Toro gas-
powered and electric leaf blowers. All the readings were taken at 50 feet from the source. The two-
stroke gas-powered leaf blower’s reading was 77-78 dBA, while the four-stroke engine gas-
powered leaf blower’s readings were 66 dBA. The electric leaf blowers had a higher pitched sound
and the readings were 71 dBA. It should be noted the local ambient was 60 dBA when the readings
were taken, which would normally raise the meter readings of the equipment.
Alternative Clean-up Tools
Staff investigated the different types of tools that are used for clean up purposes and compared the
time it takes to do the work to the time doing the same work using a gas-powered leaf blower.
Rakes/Brooms - The most commonly used tools for clean up of yards, open spaces, grounds, etc.,
are rakes and brooms. Obviously, brooms are the quietest and result in the least amount of pollution
(although some minimal pollution occurs when dust particles become disturbed during sweeping
and raking). Brooms, however, can only be used on certain types of flat, smooth surfaces such as
asphalt and concrete that are amenable to sweeping.
The time it takes to sweep an area is considerably longer than the time it takes using a blower.
Depending upon the reference source, the time differences range from three to five times longer.
According to industry standards published by the California Landscape Contractors’ Association, a
nonprofit organization that represents approximately 2,500 State-licensed landscapers, there is an
average ratio of one hour of labor using a leaf blower compared to five hours for sweeping. The
Bay Area Gardener’s Association informed staff that on average it takes its members approximately
two hours to complete a raking and sweeping job that would otherwise take one hour using a leaf
blower.
Another tool that is frequently used is rakes. They produce some noise when used on hard surfaces.
A metal rake on concrete can generate 58-60 dBAs at 50 feet. The associated time for clean-up
using rakes is about the same as it is for brooms.
Electric Leaf Blowers - While electric leaf blowers are now as powerful as gas-powered blowers,
they present substantial hazards to the users, and produce as much, if not more noise and disburse as
much particulate matter as gas-powered blowers. There are issues of the unavailability of electric
outlets; the inherent dangers of using extension cordS at a job site where other power gardening
equipment is concurrently being used or in an area that is wet, creating potential electrocution
hazards; and the impracticable nature of using lengthy electrical cords on large parcels.
Additionally, a common practice of using gas-powered generators to power electric leaf blowers
CMR:281:05 Page 5 of 13
creates substantial noise issues, not to mention even greater gas emissions that gas-powered
blosvers:
Many of the electric product manufacturers do not furnish dBA ratings. Those that do range from
64 dBA to 69 dBA. A lot depends on the power of the blower itself. The more power~ the louder
the motor noise and the noise of the air flow coming out of the tube.
Water - Water has been used in the past in many places to rid hard surfaces of debris. In non-
drought years, hoses are frequently used in residential areas to clean driveways and sidewalks.
Some cities, including Palo Alto, use power washers to clean their commercial areas. This
equipment generates noise levels that are as loud as or louder than leaf blowers. While the use of
water usually does not create air pollution problems, water i~ a scarce resource that should not be
Wasted, especially during drought years. This method creates the situation where particular matter
is washed into the Bay, which could be considered unhealthy to the environment.
Other Tools - The Green Machine has been a useful tool in helping to maintain cleanliness in Palo
Alto’s downtown area but it has it limitations. Cement tire stops in parking lots, tree wells, and
other obstacles prevent its use in certain areas and restrict its ability to pick up debris in certain
areas.
Other Cities’ Experience
Cities develop regulations according to their own specific needs and factors such as amount of
commercial and open space areas located within their jurisdiction, the level of cleanliness their
community demands, and the amount of expenditures they determine acceptable for ensuring
compliance to the regulations. Some cities do not regulate the use of leaf blowers at all.
W.hile a number of cities have banned leaf blowers, staff has determined that the enforcement
ranges from minimal to none at all. Many cities in Southern California have banned the blowers.
However, there is minimal enforcement due to the lack of resources available to conduct
enforcement. Many manufacturers mentioned the sales of gas-powered leaf blowers increased in
Southern California over the last several years, which tends to support the lack of enforcement
efforts. The majority of the cities in Santa Clara County allow the use of both gas-powered and
electric blowers, but they may be operated only during specific hours and on specific days of the
week. Attachment B provides a matrix of other California cities regulations on leaf blowers.
Currently, in Santa Clara County, Los Altos is the only city to ban gas blowers. Los Altos has a
system that allows citizens to mail in information about potential violators. Once the information is
received by the Police Department, a warning letter issentto the home or business owner where the
potential violation took place. After two warning letters are mailed, Section 11.10.060 of the Los
Altos Municipal Code is used, if needed, for compliance. This section makes it unlawful for any
person or entity to maintain, create, cause or permit a public nuisance. Failure to comply may
CMR:281:05 Page 6 of 13
result in citations issued and a mandatory appearance before a hearing officer, with the possibility
of additional fees and civil penalties imposed.
When this program began, the Los Altos Police Department received approximately 100 calls a
month; after a few months, however, the calls diminished to 15 calls per month. There is a Code
Enforcement Officer assigned to monitor the complaints and this officer is responsible for sending
the property owner a letter insisting that gas-powered blower operations cease. The results have
been positive and many homeowners comply when faced with a threat from the city. Los Altos
Police Department believes this approach has improved the environment and the quality of life for
its residents.
Enforcement in Palo Alto
Proactive enforcement did not begin in Palo Alto until the first part of 2002 for several reasons.
Staff had underestimated the numbers of commercial gardeners who needed to be trained and
certified. Due to the large numbers, the training/certification process took significantly longer than
originally anticipated. According to Department records, approximately 1,600 gardeners have been
trained and certified. Due to other changes in the noise ordinance regarding construction noise,
training for Community Service Officers and officers was delayed until December 2001. As a
result, full proactive enforcement efforts actually began in the first part of 2002.
The number of calls-for-service related to leaf blowers has decreased. In 2001, there were 131 calls
for service for leaf blowers; in 2002, 125 calls; in 2003, 88 calls; in 2004, 89 calls; and year-to-date
in 2005, 31 calls. Since 2002, 22 citations have been issued. Staff concedes that enforcement,
especially that is proactive, did not take place at an acceptable level. Higher priority calls-for-
sei-vice frequently delayed response times so that by the time an officer arrived, the gardener had
already left. Additionally, the Community Service Officer position that had been approved by
Council to focus on the education and enforcement aspects was eliminated in 2003-04 due to budget
cuts. Another reason that the calls-for-service have declined may be that some Citizens-became
frustrated and stopped reporting potential violations because the police response could not be done
in a timely manner.
Staff believes, however, that the education and certification process for commercial gardeners has
resulted in some improvements. As an example, while improvement is still needed in this area,
Public Works staff reports that they have seen a decrease in the amount of debris blown into the
streets over the last several years. Staff also believes the education and certification of so many
gardeners has helped to ensure that more gardeners use the equipment properly and comply with the
ordinance.
Staff would propose using the last patrol CSO to manage and facilitate the education, certification,
and enforcement efforts for leaf blowers. However, this would result in even longer delays, or in
CMR:281:05 Page 7 of 13
some cases no response, to cold theft cases, non-injury accidents, other noise complaints, etc. that
have heretofore been handled by CSOs.
Community Outreach
Staff conducted two publicized open forum meetings to seek community input. The first meeting
was held on April 7, 2005, and was specifically intended to obtain comments from gardeners,
landscapers and other individuals who use leaf blowers as part of their daily job. Approximately
100 professionals attended the meeting. All of the individual gardeners and those representing
larger organizations were unanimous in their strong recommendation to retain gas-powered leaf
blowers. For them, gasoline-powered leaf blowers are critical tools necessary to getting the work
done in an efficient and timely manner. The ban of gas-powered leaf blowers would require sizable
cost increases to customers for the same service. Individual gardeners would no longer be able to
maintain the same number of clients as the time to complete each job would be doubled. Many
spoke of the quietness and clean, burning nature of the newer gas-powered leaf blowers.
On April 26, 2005, a second meeting was held to seek input from residents and business owners.
Approximately 80 to 90 people attended, the majority of which wanted a total ban on leaf blowers,
gasoline and electric. Many complained about noise and the exhaust emissions the blowers
produced and how they were detrimental to the environment and people’s health. Others expressed
concern about the airborne particulate matter. Some speakers suffer from severe allergies and
asthma and explained how leaf blowers create unhealthy air quality which exacerbates their
condition. The overwhelming majority of those who spoke against the continued use of leaf
blowers were residents who, for various reasons, are normally home during the day and therefore
are more routinely exposed to the negative impacts of leaf blower use.
As mentioned previously, another frustration raised by residents is the seemingly futility of calling
the police to report violations. Some spoke of firsthand experiences about calling the police, only to
observe the gardeners leave prior to the officers’ arrival. Their experience has resulted in their not
reporting violations any longer. Afew of the speakers indicated that they did not report leaf blower
violations because they did not want to "bother" the police or take them away from more important
corlcerns.
These meetings and related publicity and news coverage generated numerous other e-mails, letters
and telephone calls from community members, gardeners, and business owners. The opinions
expressed have been comparable to the meetings: residents tended to support a leaf blower ban or
far greater restrictions, and gardeners emphasized the tremendous hardship a ban would create and
pointed to the quietness and efficiency of the newly manufactured leaf blowers as an amicable
solution. Some residents, however, have expressed a desire to not go forward with the ban. ¯
Bay Area Gardeners’ Association
CMR:281:05 Page 8 of 13
Prior to June 2001, the training and certification process for commercial gardeners had been
administered by Police Department staff several times each month. When the CSO position was
eliminated in 2003-04, staff decided to have BAGA take over administration of the process, with
the training/testing sessions being held at their Redwood City facility. A Police staff member
attends and is responsible for correcting the tests and issuing the certification cards.
This last year, staff has met with BAGA Board Members on several occasions. The interactions
were very productive. After reviewing the CARB Tier standards and learning that manufacturers
are required to meet the CARB standards, it was clear a recertification program needed to be
implemented. BAGA expressed its desire to facilitate a program that would require commercial
gardeners working in Palo Alto to get recertified and to buy new leaf blowers if the leaf blowers
currently being used did not meet the CARB Tier II standards. BAGA Board Members
recommended a one-year grace period for the gardeners to purchase the new equipment.
The recertification program would educate commercial gardeners about the CARB Tier standards,
changes in technology and how it has improved leaf blowers, and the requirement that gardeners
purchase new leaf blowers that have lower dBA ratings and decrease the amount of exhaust
emissions. A portion of the recertification class would remind and educate the commercial
gardeners about the proper use of the leaf blower. It would also inform the gardeners on any change
to the Municipal Code. The current educational material will be updated and the CSO would assist
BAGA with the recertification program.
City Crews and Contractors
Currently the costs to maintain parks and City facilities in residential areas using gas-powered leaf
blowers is $585,500.
A ban of gas-powered leaf blowers in residential areas would have a substantial financial impact on
the City’s Community Services and Public Works Departments. To maintain the same level of
cleanliness in the City, staff estimates the ban On these blowers and the resultant switch to
performing the work manually would increase Costs by over $1 million annually (Attachment C).
POLICY OPTIONS
Staff has considered alternative options for dealing with the leaf blower issue. The pros and cons
for each of these alternatives are provided.
1)Make no changes in the current ordinance that prohibits the u~e of all leaf blowers in
residential areas:
Pros:
CMR:281:05 Page 9 of 13
The quality of life concerns raised by residents associated with noise, particulate matter,
exhaust emission and topsoil damage would decrease.
Enforcement of leaf blower violations would be more straightforward, in that operational
noise measurements, proof of gardener certification and equipment compliance
verification would be eliminated.
C ons:
¯Most likely would result in sizable cost increases to customers for the same service.
Individual gardeners would need more employees or longer periods of time to complete
the same job sites. Gardeners have informed staff that without leaf blowers, the time to
complete each job. is doubled.
¯Residents would also be prohibited from using leaf blowers.. ¯
¯Apartment complex owners and association-governed complexes would more than
likely pass added maintenance costs on to tenants.
¯Absent the use of leaf blowers and the convenience and ease of cleanup they afford,
there is a possibility that the amount of homeowner .debris being picked up disposal
would be lessen.ed, consequently there are additional concerns regarding the impact to
storm drains and flow to Bay.
°Residents not cleaning up the sidewalks and gutters, can be expected. Residents and
their contractors would no longer be blowing out under parked cars leaving additional
debris to eventually find its way to the storm system.
° There will be significant costs to continue maintaining City parks, open space and
publicworks projects
°Initially, staff believes there would be an increased number of calls-for-service and a
higher expectation of timely enforcement of leaf blower violations.
2)Prohibit the use of only gas-powered leaf blowers in residential areas:
Pros:
o Exhaust emissions and use of fossil-fuels would be reduced.
Cons:
Many of the commercial grade electric blowers produce a higher pitched noise level
whieh some believe to be more intrusive that the newer combustion-powered blowers.
The use of gas-powered generators, which produce higher noise levels and significant
gas emissions would increase.
CMR:281:05 Page 10 of 13
There will be additional costs to continue maintaining-City parks, open space and public
works projects as they replace existing equipment and contractors would increase their
costs to the City due to the change in equipment.
Added costs and limitations of commercially available electric or battery-operated
blowers would increase commercial gardener’s expense and time to complete a given
job.
The inherent safety hazards created by the use of electrical equipment in an outdoor
environment and the use of extension cords would increase.
Apartment complex owners and association-governed complexes would more than
likely pass added maintenance and equipment costs on to tenants.
3)Prohibit the use of leaf blowers used only by City crews and commercial gardeners in
residential areas:
Pros:
The noise levels associated with leaf blowers would theoretically decrease, especially
during the primary complaint periods, daytimes, Monday through Friday.
See #1.
Cons:
See #1.
Because residents Would be allowed to use their individuals leaf blowers, the issue and
concerns over noise levels, exhaust emissions, particulate matter and damage to top soil
would continue to exist, although to a lesser degree.
Prohibit the use of leaf blowers by commercial gardeners in residentiai areas but exempt
City crews and contractors:
Pros:
®Many of the pros would be the same as identified in policy option #3.
The costs associated with parks, open spaces and public works
equipment would not increase.
C Oils:
®Creates a double standard for the City.
See #1.
operations and
CMR:281:05 Page 11 of 13
Since City crews would be allowed to operate in residential areas, those citizens who
live in and around these areas would still be impacted by the noise, exhaust emissions,
and damage to topsoil as propagated by City equipment or City contractors.
RESOURCE IMPACT
Depending upon Council’s decision, costs associated with maintaining the current level of
cleanliness in City parks and facilities in residential areas would increase to approximately
$1,123,700 annually (Attachment C). Since the City’s costs are anticipated to double, it can be
anticipated that homeowners’ costs would increase by a commensurate amount.
The cost of a dedicated CSO is $76,682, which includes salary and benefits.
POLICY IMPLICATIONS
This will be dependant on the decision the City Council makes.
ENVIRONMENTAL REVIEW
This project is categorically exempt from the California Environmental Quality Act (CEQA) as it
restricts the use the leaf blowers for environmental protection purposes.
