From: City Manager
Lead Department: Public Works
Recommendation
Staff recommends that the Finance Committee:
1. Discussion of a new residential curbside collection and composting program
of food scraps commingled with yard trimmings in the green carts, effective
July 1, 2015;
2. Accept Staff’s preliminary recommendations to extend GreenWaste of Palo
Alto’s Agreement for Solid Waste, Recyclable Materials, Organic Materials
and Yard Trimmings Collection and Processing Services (GreenWaste’s
Contract) through June 30, 2021 and develop amendments that would help
increase diversion and efficiencies;
3. Accept Staff’s preliminary plans to adopt and implement a new City
ordinance that would require businesses to subscribe to commercial
City of Palo Alto Page 2
compostable service and sort their wastes so that there will be less than
10% contamination in any container;
4. Accept Staff’s preliminary plan to develop and implement a new refuse rate
structure along with a three year schedule to increase refuse rates charged
to the Residential Sector;
Executive Summary
The implementation of the GreenWaste Contract in 2009 added several zero
waste programs that boosted the City’s diversion rate (from landfills) from 62% in
2008 to approximately 78% in 2013. Since then, the City’s waste diversion rate
has not increased as desired, especially given our Zero Waste Goal by 2021. The
next big step in the City’s efforts to attain its zero waste goals is getting
compostables out of the landfill, as they make up 40% of today’s garbage. In this
report, Staff proposes a series of activities to keep the compostable materials out
of the landfill, which include: modifying the GreenWaste Contract, providing
residential food scrap collection, and adopting an ordinance requiring commercial
customers to recycle and compost in an optimal manner. Staff is also proposing
to modify the City’s Refuse Rates to encourage recycling and composting while
balancing residential and commercial rates. Staff recommends pursuing the
following three new diversion related actions:
1) Collect residential food scraps curbside commingled with yard trimmings,
beginning July 1, 2015;
2) Amend the Contract, extending the term until 2021, and focusing on the
collection and diversion of residential food scraps comingled with the yard
trimmings and commercial food scraps; and
3) Implement an ordinance that would require commercial customers to
subscribe to a rigorous composting and recycling service.
These three actions can be accomplished in an efficient and cost-effective manner
and are forecasted to divert and recover 7,000-8,000 tons of compostable
material currently being landfilled every year for less than a three percent overall
budget cost increase of $790,000. The result of this diversion should increase the
Palo Alto diversion rate from 78% to approximately 82%, higher than most other
City of Palo Alto Page 3
cities in the United States and reduce greenhouse gas emissions by over 3,800
metric tons of CO2 equivalent each year.
Refuse rates have not increased since July 1, 2012 and in fact were decreased in
November 2014 due to the change in service delivery model for the street
sweeping program. Staff is also recommending a three-year plan to adjust
Residential Refuse Rates to an amount that will cover these new diversion related
expenses as well as balance Residential and Commercial rates. While the amount
of the rate increase required is still being determined, preliminary analysis
suggests that the residential rates would need to be increased by approximately
9% in FY 2016 and 8% in both FY 2017 and FY 2018 for mini-can and 32 gallon
containers. Changes to the rates for FY 2016 will be incorporated into the FY
2016 budget process. Staff is also recommending a structural change to the
Refuse Rates that would eliminate listing fixed charges on monthly bills, in
addition to improving the refuse billing system accuracy by contracting with
GreenWaste to perform this function in the commercial sector.
Background
In 2005, the disposal of recyclable and compostable materials in landfills
represented 10% of the greenhouse gas emissions for the entire Palo Alto
community. That year, Council adopted a policy to achieve Zero Waste by 2021.
In 2007, a Zero Waste Operational Plan (ZWOP) was developed that identified
specific actions necessary to achieve zero waste. The City has made tremendous
progress implementing zero waste programs over the past seven years. The
diversion rate, which was approximately 60% in 2005, had increased to
approximately 80% in 2010 then leveled-off (or slipped a little due to the increase
in economic activity in the City) since then because the diversion programs such
as the commercial compostable collection program have been fully implemented
as designed. This increased diversion from landfills has resulted in significant
reductions in greenhouse gas emissions. One of the major programs that has
helped the City drive towards zero waste is the collection of commercial
compostables (e.g., food scraps, food soiled paper, and compostable plastics).
Over 11,000 tons of commercial waste annually has been diverted from landfills
and composted. Yet, commercial customers still send over 7,000 tons of
compostable material to the garbage. The commercial customers’ collective
garbage also is filled with over 6,500 tons of recyclable materials. While some of
the recyclable material in the garbage is recovered at the Sunnyvale Material
City of Palo Alto Page 4
Recovery and Transfer (SMaRT) Station, the compostable materials placed in the
black garbage carts are nearly all lost to the landfill.
Compostable Material
GreenWaste took over curbside refuse collection in July 2009 (CMR 416:08),
implementing a number of new zero waste programs including a commercial
compostable collection program and worked aggressively to add customers to the
compostables collection program. A mandatory recycling and composting
ordinance was considered in 2009, but was never implemented. Staff began
discussions to implement the ordinance in 2010, however, later that year when
the Refuse Fund incurred large deficits following the recession Staff shifted
priorities to focus on cost savings measures. In 2013 and 2014 GreenWaste
focused on reducing the level of contamination in the composting containers.
While some new customers have added compostable service, the amount of
compostable material collected has remained relatively flat.
FY 10 FY 11 FY 12 FY 13 FY 14
Commercial Compostables
Recovered (tons per year) 10,247 11,932 11,723 11,688 11,487
Recovering compostable materials placed in garbage carts is not limited to
commercial customers. Based on a 2012 Waste Characterization Report, over
one-half of the material placed in residential garbage – 5,000 tons - is
compostable and approximately one quarter is recyclable. Unlike commercial
customers, residents in single-family households currently do not have a food
scraps collection option. A Curbside residential food scrap collection program
was identified as a priority project in the 2008 Zero Waste Operational Plan;
however, due to the added rate increase that would have been needed to pay for
the program, it was not implemented with the inception of the GreenWaste
contract in 2009 resulting in only yard trimmings collected curbside in the green
cart. Currently, most single-family residents dispose of food scraps in the garbage
or through a kitchen sink grinder – options that negatively impact the
environment. Some residents, about 10%, compost at home, which is the best
environmental option.
Curbside collection of food scraps and food soiled paper is a widespread and
successful practice throughout the Bay Area. Staff has worked to identify the best
City of Palo Alto Page 5
curbside collection method for these compostable materials. In April 2013, the
City implemented a year-long Two Cart Collection Pilot Program in the
Greenmeadow neighborhood that eliminated the black (garbage) carts. Residents
were asked to change two behaviors: first, place food scraps into compostable
bags and then into the green carts combined with yard trimmings; secondly,
residents were to bag any remaining garbage and place it in the blue recycling
carts. Both of the carts (blue and green) were collected weekly and sorted at a
materials recovery facility (MRF).
The Two Cart Collection Pilot Program confirmed that the two-cart collection
system is a good method to increase diversion of food scraps and additional
recyclables from landfills. However, the method of separation in the pilot was
complicated, as residents were required to: 1) Separate food scraps from yard
trimmings using compostable bags; and 2) Separate garbage from recyclable
materials using plastic bags. Because of these complexities that led to confusion
by residents in the pilot area, Staff is not recommending a citywide roll-out of the
two-cart collection system at this time. Staff is recommending a simpler option
where residents can place their food scraps bagged or loose in the green carts, as
is described later in this report.
GreenWaste Contract
The current Contract with GreenWaste of Palo Alto, a joint venture (GreenWaste)
has an initial term of 8 years with a provision to extend up to 4 additional years
(through June 30, 2021). The agreement has provisions for GreenWaste to
provide six new zero waste services, five were implemented in 2009. A sixth zero
waste service would have added a mandatory recycling and composting
participation ordinance but it was never adopted. Staff shifted priorities to focus
on cost savings measures when the Refuse Fund incurred large deficits following
the 2008 recession.
Refuse Rates
To obtain better estimates of the existing residential and commercial refuse fund
costs, Staff initiated a cost of service study in 2012. The study found that the
Refuse Fund’s commercial and residential sectors revenues were not in balance,
and began to modify rates in FY 2013 to achieve the proper balance. The
residential rates, which have been in effect since July 1, 2012, include a variable
charge for the black, garbage cart (mini-can, 32-gallon, 64-gallon, 96-gallon), and
City of Palo Alto Page 6
fixed charges for Street Sweeping, Household Hazardous Waste (HHW), and the
Annual Clean-Up Day.
The City bills waste collection for three different sectors: residential, commercial
and roll-off. Staff also determined the rate plan provided residential customers
taking large garbage cart service with a smaller percentage rate increase
compared to the rate increase imposed on residential customers with mini-can
service. This message runs counter to the City’s zero waste goals and could
potentially encourage customers to use a larger cart as it is a “better deal”. For
these reasons, and because the 2012 rate model was overly complex, Staff have
developed a new model and recommended approach which is described in the
Discussion section below. Staff has identified a number of programs where a
greater percentage of costs should be allocated to the commercial and roll-off
sectors.
Discussion
There are two main challenges that this staff report describes and addresses:
Challenge #1 The City’s waste diversion percentage rate attained has leveled off
(or dipped slightly) since 2010 and without further changes to induce an increase
in diversion, the City will not attain its zero waste goals; and
Challenge #2 The City’s refuse rates need to be rebalanced between the
Residential and Commercial Sectors, and then the rates must be increased to
cover the costs of the new programs described in this report.
Addressing Challenge #1: The City’s Waste Diversion Rate has Leveled-off Since
2010
After a dramatic increase in diversion since new zero waste services were
implemented in July 2009, the City’s waste diversion percentage has stalled for
the last three years (see graph below). If the City is to reach its 2021 zero waste
(to landfills) goals, then more aggressive program activities will be needed to
“jump-start” the City’s diversion rate. Staff has identified that the largest
diversion opportunity in the garbage is compostable organics – food scraps and
food soiled paper, which constitutes over 40% of the current garbage stream.
City of Palo Alto waste diversion rate over time:
City of Palo Alto Page 7
Below are three actions Staff is proposing to divert 7,000 to 8,000 tons per year of
waste, primarily food waste, currently being landfilled for an overall Refuse Fund
cost increase of less than three percent. These actions to divert and recover
waste from landfills will help the City meet its Zero Waste program goals, while
keeping Palo Alto a leader in sustainability. The three actions are outlined below:
1. Collect residential food scraps curbside commingled with yard trimmings in
a new residential food scraps collection program.
2. Adopt and implement a recycling and composting ordinance that would
require commercial customers to sort their waste so that food scraps can
be recovered and composted.
3. Modify the Contract and add new zero waste services that focus on the
largest source of unrecovered material in the garbage stream (food scraps
and food soiled paper).
City of Palo Alto Page 8
New Residential Food Scraps Collection Program
Staff is recommending the city-wide collection of residential food scraps (bagged
or loose) commingled in the green carts with yard trimmings. Commingling the
food scraps with yard trimmings is the simplest way to recover this material,
divert it from the landfill, and produce valuable compost. Many cities throughout
the Bay Area have been collecting and composting commingled residential food
scraps with yard trimmings for several years. There are several regional
composting facilities that are permitted to compost commingled food scraps and
yard trimmings. The food scraps collection program will likely divert and recover
over half (or approximately 3,000 tons per year) of the food scraps in the
residential garbage.
In addition, a curbside food scraps collection program that allows for the loose
placement of food scraps in the green yard trimmings cart is consistent with the
City’s commercial compostable materials collection program. No longer will
school children sort one way at school (part of the commercial program) and then
another at home (part of the residential program for single family residents). The
improved consistency between the residential and commercial programs will
improve outreach opportunities and effectiveness. The proposed program also
will be consistent with the other Bay Area communities, including Menlo Park,
San Francisco, San Mateo, Redwood City Atherton, Berkeley, and Oakland.
If this program is approved, Staff will purchase kitchen pails and distribute them
to all single-family residences within the City. Residents can use the pails to
temporarily keep food scraps indoors until the material is emptied into the green
yard trimmings carts. The program allows for all food scraps to be composted
and placed directly into the green cart in a variety of options: loose, in a
compostable bag (paper or plastic), in a paper carton (e.g., milk, juice, ice cream),
or any other compostable container. The acceptable compostable items include
but are not limited to: spoiled food, inedible food scraps (e.g., banana peels,
apple cores), meat, bones, egg shells, compostable plastics and food soiled paper
(e.g., paper towels, used tissues, paper plates, paper cups, and paper cartons).
Larger compostable food scraps like pizza boxes or paper cartons also can be
placed directly into the green carts. Diapers, pet waste and feminine hygiene
products would not be allowed in the green carts and should continue to be
placed in the black garbage carts. Multifamily dwellings with five or more units
City of Palo Alto Page 9
that subscribe to commercial refuse service have had the opportunity to have
food scrap collection since 2009, however, many of these customers do not
subscribe to the compostables service. These customers will be subject to the
recommended ordinance.
The combined materials in the green carts will be collected by GreenWaste of
Palo Alto and transported to the Sunnyvale Material and Recovery Transfer
(SMaRT) Station for consolidation. The material will then be transported to a
regional composting facility for processing and composting. The regional
composting facility will either be: 1) Z-Best Composting Facility near Gilroy (a
sister company of GreenWaste of Palo Alto); 2) Zero Waste Energy Development
Company (ZWED) (also a sister company of GreenWaste) in San Jose; 3) Newby
Island Composting Facility operated by Republic Services in Milpitas; or 4)
Harvest-Lathrop Composting Facility (a sister company to Harvest Power) located
outside Lathrop. If the City decides to utilize the ZWED facility in North San Jose
then the material would be directly hauled to that facility by GreenWaste,
bypassing the SMaRT Station due to ZWED’s close proximity to Palo Alto.
A Budget Amendment Ordinance for $387,000 will be needed to fund the
purchase of the outreach and training materials that will be needed to implement
this new program by July 1, 2015.
Home Composting
The residential curbside collection of food scraps does not reduce the need or
importance of home/backyard composting. Home composting is a great option
for many residents to recover most food scraps. Home composting helps to
reduce collection costs and lower greenhouse gas emissions and also provides a
“closed-loop” for the food scraps. It is estimated that less than 10% of Palo Alto
household’s compost at home. In 2014 Staff implemented an expanded home
composting campaign to increase participation citywide. The expanded campaign
has been a focused outreach and incentive-based campaign that has augmented
and added emphasis to the City’s traditional, ongoing, multi-partner program for
home composting, water conservation, and pollution prevention. The expanded
campaign’s goal has been to raise awareness about the benefits of home
composting while increasing the number of people composting at home and using
compost in the yard/garden. Also, the expanded campaign has aligned with
California’s drought as it encourages home composting by highlighting compost’s
City of Palo Alto Page 10
water-saving properties, and through incentives such as the City providing free
home composting bins to Palo Alto residents. In 2014, 159 residents attended 15
composting workshops where Staff gave away 82 backyard compost bins.
Home composting will continue to be an important City waste diversion program
complementing residential curbside food scrap collection, but it will not work for
everyone and will not be able to accept all of types of compostables, as described
below. Surveys conducted in 2014 indicated that two-thirds of residents actively
chose not to have backyard compost. Residents cited time constraints and not
gardening as the main reasons. Many do not have space available for home
composting, or perceive home composting as smelly and an activity that can
attract rodents, flies or other bugs to their home. In addition, some types of food
scraps and yard trimmings should not be placed into a home compost feedstock
including various vegetation seeds, meat, bones, dairy products and fats. With
the proposed curbside Residential Food Scraps Collection Program, this type of
food waste can be placed in the green cart and commercially composted. Home
composting and curbside food scrap collection complement each other by
providing a complete solution to maximize the environmental benefit for all
household organics.
New Recycling and Composting Ordinance
The latest Waste Characterization Study, performed in 2012 showed that 25% of
the material in the commercial garbage was recyclable and 40% was compostable.
A small amount of the recyclables in the garbage is recovered at the Sunnyvale
Material Recovery and Transfer (SMaRT) Station where all of Palo Alto’s garbage
is processed before being sent to a landfill. However, nearly all of the
compostable materials end up in the landfill along with the garbage. Other cities
and counties have recently adopted mandatory recycling and composting
ordinances (food bans) and have had good success diverting their waste from
landfills including San Francisco, Oakland, Vancouver, Portland, New York and
most recently Seattle.
The majority of the businesses in Palo Alto have recycling service. However, as of
October 2014, only 477 of 1,615 commercial accounts take compost service. In
addition, of the 197 food service establishments where Staff would expect
generation of a high percentage of food waste, only 123 take compostables
service. In order to identify why businesses are not electing to subscribe to
City of Palo Alto Page 11
compost service, in early 2014 Staff surveyed a number of businesses without
compostable service. The most common answer as to why they had not elected
to have compost service was that it was not required by the City. For many of
these commercial customers, saving a few dollars and the perceived extra for the
environment was “just not worth it.” Therefore, Staff recommends a mandatory
recycling and composting ordinance for the commercial sector.
The proposed ordinance (not yet written) would require commercial customers to
subscribe to both recycling and compostables service. In addition, customers
could not place recoverable items in the garbage. In other words, customers
must subscribe to the services, have a garbage, recycling, and compostable cart or
bin and sort properly. Staff proposes that the City takes the following actions
with customers who fail to sort properly as identified by either the GreenWaste
collection truck driver or by GreenWaste staff through a random audit. With the
first instance of a high percentage of contamination (over 10% in any cart), the
customer receives a cart tag from GreenWaste giving notice of the contamination
problem; with the second instance, GreenWaste would send a letter and staff
would follow up with a telephone call to find out if training is needed; and with
the third instance, GreenWaste would charge a special solid waste processing
(amount to be determined) for each time the customer fails to sort properly.
Staff recommends implementing the ordinance in the following phases:
Phase 1: April 1, 2016. Initiate mandatory service with all Food Service
Establishments and all commercial customers generating 8 cubic yards or
more per week of garbage. This phase would add 147 customers and would
include (but are not limited to): restaurants, markets, bakeries, bars,
farmers' markets, hotels, and catering facilities. Initiate proper sorting
procedures (as appropriate for the service they have) for all commercial
customers.
Phase 2: January 1, 2017. Expand program to commercial customers
generating at least 2 cubic yards per week of garbage. This phase would
add 223 customers.
Phase 3: January 1, 2018. Expand mandatory service to all remaining (612)
commercial customers. Staff proposes that the ordinance include a
variance procedure where commercial customers can apply to take a lesser
quantity of service than is afforded by the three collected materials
(garbage, recycling and food scraps) based on their specific waste
City of Palo Alto Page 12
generation quantities. Staff would exercise the administrative discretion to
approve the requests if warranted.
GreenWaste Contract Amendments
GreenWaste has provided waste collection and material processing services for
the City since 2009. The Contract will terminate on June 30, 2017 unless the City
elects to extend the term. The Contract permits an extension of up to 4
additional years until June 30, 2021. GreenWaste has met its performance
obligations since its inception and staff has been negotiating with GreenWaste for
the last few months to determine a cost effective way to extend the Contract,
while at the same time replace some of GreenWaste’s older vehicles and increase
diversion activities to meet the City’s zero waste goals. Staff believes that the
following concepts will achieve the balance necessary.

*There will also be a corresponding cost decrease of approximately $576,000 from
redirecting residential yard trimmings and food scraps away from SMaRT and the
Kirby Canyon Landfill.
**Staff prefers that this commercial compostables materials be processed at the
nearby ZWED Facility because it is the closest processing facility that would result
in less greenhouse gas emissions and would generate electricity through dry
anaerobic digestion. The ZWED cost per ton for FY 2016 would be $81 per ton,
2.3% higher than the expected rate of $79.19 per ton at ZBest.
1) Contract extension(No net cost impact)– The Contract commenced on
November 24, 2008 and will expire on June 30, 2017, along with a provision
to extend the contract for up to four additional one-year terms, until June
30, 2021. Staff recommends an extension of the full four one-year terms
because:
GreenWaste has been meeting and exceeding their collection and
processing scope of work thus far in the contract term;
Customer feedback is positive; the City has received minimal
customer complaints regarding the service provided;
GreenWaste has been collaborating with the City by suggesting cost
effective service changes during negotiations;
A longer term would allow the City to take advantage of collection
vehicles expected useful; and
The new term would synchronize with the City’s other major solid
waste agreements, SMaRT and Kirby Canyon Landfill, which also
expire on June 30, 2021. Subjecting the City’s collection, processing,
and landfill solid waste contracts to a competitive selection process
i.e., a request for proposals (RFP) process at the same time more
likely could provide the City with cost-effective and integrated
solutions.
If the Council were to decide not to extend the term of the Contract over
the next four years, then Staff would need to begin developing an RFP
process by summer 2015. This should provide enough time for staff to gain
consensus on the collection and processing scheme criteria, to select a
successful proposer and enough lead time for the purchase and delivery of
new collection equipment.
City of Palo Alto Page 14
2) Compostables package ($1,346,000 net increase) – Staff recommends
adding provisions to the GreenWaste contract that would increase the
recovery of food scraps and use these food scraps for energy production.
New residential food scraps collection – As discussed above,
GreenWaste would collect the City’s residential food scraps commingled
with yard trimmings and deliver the material to a processing facility
without additional fees. The material could be taken to the SMaRT
Station and be transferred to a processing facility or could be taken to
GreenWaste’s sister company Zero Waste Energy Development (ZWED),
a dry anaerobic digestion facility designated to produce electricity.
Implement a recycling and composting ordinance in the commercial
sector – GreenWaste staff will assist in the implementation of a
compliance program promulgated under a proposed recycling and
composting ordinance for the City’s commercial sector at no additional
cost, utilizing current staff assigned to the City.
Increase commercial compostables incentives – Staff recommends
modifying the contract’s current incentive clause that pays GreenWaste
for processing commercial food scraps a price per ton based on the net
tonnage (that is the overall tonnage collected minus the contamination
percentage which can typically be 10%-20%). The incentive payment
would change to paying GreenWaste based on gross tonnage collected,
which will incentivize GreenWaste to collect and divert more
compostables wastes where more effort and costs are needed to sort
the material and landfill the garbage contamination residue. Staff’s goal
is to get all of the City’s commercial customers established with the
compostables collection program and require customers to clean up
their compostable wastes through the recycling and composting
ordinance compliance requirements.
Redirect commercial compostables to the Zero Waste Energy
Development (ZWED) Facility – Staff recommends diverting commercial
compostable material to the ZWED facility in order to use the material
to produce electricity. The marginal cost increase would be $22,000 per
year. Processing this material locally, (located in north San Jose near
Zanker Road and Hwy 237) would also yield the benefit of saving
greenhouse gas emissions related to transportation of the material.
City of Palo Alto Page 15
3) Commercial billing ($150,000 net increase)– Staff recommends that
GreenWaste provide billing services to the City’s commercial sector
customers in lieu of the City hiring full time staff to monitor and maintain
the data. In 2014, the City’s Auditor conducted an audit on the Refuse
Fund and found discrepancies between the City’s SAP billing system and the
GreenWaste collection database (RAMS), which resulted in billing errors.
The errors are primarily due to the fact that the City’s billing system (SAP) is
not customized to manage the hundreds of different service levels offered
by GreenWaste. GreenWaste maintains a complete detailed customer
database that must interface with SAP. Due to changes in refuse service
and the complexities in the interface between the two databases, there
remain inconsistencies in customer account data between the two systems.
While the City and GreenWaste are continuously working together to
identify, correct, and enhance the systems to eliminate these discrepancies,
shifting the complex commercial billing to GreenWaste provides the best
opportunity to minimize billing errors at the lowest cost. Staff’s response
to this audit concern was to recommend either shifting the billing to
GreenWaste or by adding a position to focus on software improvements
and on the fulltime monitoring and maintenance of the data.
GreenWaste providing commercial refuse billing services will cost
approximately $150,000 per year, increasing the total cost of Refuse
related billing services from $250,000 to $400,000. The residential refuse
bill will remain on the consolidated City Utilities bill. The Public Works
Department will work with the Utilities Department to identify the resulting
savings from this proposed change in the service delivery model, and, if
approved, it is anticipated that a reduction to the annual transfer will be
recommended for City Council approval following the implementation of
the change.
4) Variable costs ($70,000 net decrease)– The variable cost related
amendments involve rolling the itemized cost items such as the special
events and hard to serve areas into the Contract’s base compensation. The
City would save about $70,000 per year.
5) New trucks/cart purchases ($55,000 net decrease)– GreenWaste will
purchase new automated trucks to replace the oldest six trucks that collect
City of Palo Alto Page 16
residential yard trimmings and garbage. These trucks are older than the
rest of the GreenWaste fleet because GreenWaste purchased these trucks
from the City’s previous contracted hauler, “Palo Alto Sanitation Company”.
The new, more fuel-efficient trucks will run on compressed natural gas
(CNG). The new trucks will be fully-automated, that is, will have loading
“arms” to reach and pick up the waste containers from the curb. These
new automated trucks will allow for just one driver to service residential
routes instead of a driver plus a helper as is currently the case, resulting in
the reduction in cost of 4 fulltime positions. Replacing the older trucks
provides a net savings of $55,000 per year to the City due to the reduced
operating costs. A change to the current cart placement procedures would
need to be implemented – the carts would need to be placed on the street
so that the automated arms can reach the carts as opposed to the current
practice of placement at the curb (i.e. near the sidewalk). GreenWaste will
continue to utilize semi-automated trucks in areas where parking is a
problem. Moving forward, GreenWaste will also be responsible for the
purchase of all replacement carts.
6) Minor administrative changes – These changes involve less substantial
items with no cost impacts but are needed for contract compliance and
require an amendment to the contract. Some changes involve
modifications to the measurement criteria, the schedule to allow
reconditioning of containers, and past letters of intent that have already
been agreed between the City and GreenWaste.
Addressing Challenge #2 - The City’s refuse rates need to be adjusted between
sectors, then increased to cover the costs of the new programs described in this
report.
As mentioned above, In May 2012, Council approved a single-family residential
(residential) rate plan to address an imbalance between the sector revenues and
expenses. The residential rates, which have been in effect since July 1, 2012,
include a variable charge for the black, garbage can or cart (20- gallon minican,
32-gallon, 64-gallon, 96-gallon), and fixed charges for street sweeping, household
hazardous waste (HHW), and the annual Clean Up Day.

*The street sweeping charge was originally $6.66 and was reduced to $5.26 in November 1,
2014, with the new street sweeping contract.
The residential rate plan presented by staff to the Finance Committee in April
2012 suggested a three year phase-in, which would have resolved the sector
imbalance with a combination of fixed percentage and flat increases to rates (also
referred to as Option 8, see Staff Report 2706 for details). Staff, however, wished
to further study allocation of costs between the sectors and elected to postpone
the rate increases in order to do so. Staff subsequently identified a number of
programs where a greater percentage of costs should properly be allocated to the
commercial and roll-off sectors. The most significant program cost was relative to
the landfill closure and ongoing maintenance activities, which are costs that
should have been allocated to the commercial sector at a greater percentage,
since these sectors contributed the most material to the landfill.
A consultant study was commenced in 2014 in order to update and evaluate the
cost allocations among the sectors. The report from the City’s consultant is
currently being finalized and has shown that the residential service rates need to
be raised by approximately 28% (mini-cans and 32 gallon garbage service) to fully
cover the cost of the service (See table below). Staff recommends adjusting the
rates over a three year period. Staff also recommends changing the bill, including
moving away from listing the separate fixed charges currently on the residential
utility bills.
Staff suggests adjusting the residential monthly rates in the table below to
provide for an equitable distribution of costs while encouraging zero waste
behaviors. Staff recognizes that increases of this size should be accomplished over
a three year period in order to soften the cost increases for the residents. These
City of Palo Alto Page 18
residential rate increases also include costs for a vital programmatic change, a
new single-family residential curbside food scrap collection program.

Notes
1. Rates include street sweeping, household hazardous waste, and the annual clean-up
day.
2. The table above shows projected rate modification over 3 years. Staff would only bring
forward rate adjustments 1 year at a time.
3. Projected fees assume a revenue loss from the migration of 5% of residents moving to
smaller carts. However, based on actual customer choices to move to smaller cart sizes,
the annual increases may be different.
Rate Structure Modification
Staff proposes that the monthly Refuse Rate include all of the residential services
costs in the one price (listed in the table above), instead of separating fixed
charges, currently for street sweeping, household hazardous waste, and the
annual clean-up day on the bill. One advantage of this is when there are year to
year changes in these fixed costs (contract pricing, CPI adjustments, etc.) Staff will
not necessarily need to raise the refuse rates every year in order to ensure that
the fixed fees will adequately fund each fixed costs; rather, the refuse rates will
be set to ensure cost recovery of the entire service provided to customers. In
addition, Staff has identified many other costs such as recycling service,
compostable service, some SMaRT Station costs, and landfill maintenance costs
that could also be listed separately as a fixed fee but would not be practical or
possible with the SAP current billing system.
City of Palo Alto Page 19
Staff calculated the single family residential monthly rates (listed in the table
above) with the following three-step method:
1) First, add the fixed costs per single family residences for street sweeping,
household hazardous waste program, annual Clean Up-Day, recyclables in
the blue cart service, yard trimmings in the green cart service and landfill
postclosure maintenance to determine a combined fixed cost per
residence.
2) Second, calculate a cost per gallon for the garbage cart by dividing the
overall costs of residential refuse service by the total number of gallons of
service within the City. This would yield a variable cost per gallon that
would be used to calculate the variable cost per service for refuse
collection.
3) Finally, calculate the final monthly fee by adding the fixed cost per
residence to the variable cost of the black garbage cart to generate the
monthly fee for the 32-gallon cart. Other service levels (various garbage
cart sizes) would be based on the 32-gallon base rate. The 64 and 96-gallon
cart customers will pay double and triple the 32-gallon rate respectively. A
minican (20-gallons) is roughly two-thirds the size of a standard 32-gallon
cart. Therefore, the minican customers will pay roughly 2/3rds of the 32-
gallon rate less minor cost adjustments to the mini-can rate thus
incentivizing recycling and composting.
Commercial Rates
In order to bring the Refuse Fund Reserve to the required percentage, Staff
recommends that most of the commercial garbage rates should be maintained at
the 2012 rates until the costs and revenues received for these services are
balanced (expected by FY 2017).
Staff recommends a rate reduction to the commercial compostable materials
service (green cart/bin) once the recycling and composting ordinance is
implemented. Compostable materials service currently is provided at a 10%
percent discount by comparison to garbage service of the same size container.
Staff has initially calculated that the actual cost of this compostable materials
service may warrant a steeper discount for compostable service (30% discount)
City of Palo Alto Page 20
compared to garbage service, both of which use the same size container. The
discount would offset the additional costs incurred by customers adding
compostable service as part of the mandatory recycling and composting
ordinance. Some customers may realize cost savings on their refuse bill with
proper refuse sizing and sorting. Staff expects revenue losses as a result of the
discounted commercial compostable service will be offset by the new revenue
from new customers subscribing to compostable service as required by the
mandatory recycling and composting ordinance.
Should Council choose to create a recycling and composting ordinance coupled
with the new reduced compostable rate structure, initial estimates show that
commercial customers could divert an additional 4,000-5,000 tons annually of
food scraps and other compostables from the landfill. Removing the discount on
the service or not implementing the recycling and composting ordinance likely
would decrease participation and significantly reduce the environmental benefits
of the program.

Resource Impact
The cost to the Refuse Fund for all of these program modifcations would be
approximatly $790,000 per year, beginning in FY 2016, which is equivalent to
approximately a 2.7% overall Refuse Fund expense increase. The major cost
implications are:
GreenWaste Contract/Scope Changes $1,366,000 per year increase
SMaRT/Kirby Canyon decrease ($576,000) per year decrease
$790,000 per year net increase
It should be noted that the rate increase recommended for FY 2016 may be
higher than 2.7% pending a full analysis of the increased costs in the Refuse Fund.
Further, since 2010, Staff has aggressivly implemented cost savings measures
listed below. These cost savings measures have made it unnecesary to implement
a Refuse Rate increase since 2012, and will minimize the impacts of the new zero
waste measures discussed above. The cost saving measures which have been
implemented are:
Expediting the landfill closure through a “fast-fill” program, closing the
City of Palo Alto Page 22
landfill early, reducing staff and equipment, saving $2.1million per year in
operating expenses (2010 budget compared to FY 2015 budget);
Closing the Recycling Center in FY 2012 saving $225,000 per year; and
Modifying the street sweeping program, modifying the frequency of
sweeping during the non-leaf season and contracting out a large portion of
the work, saving the City $649,000 per year ($522,000 to the Refuse Fund).
The Refuse Fund is in the process of rebuilding its financial reserves. The Rate
Stabilization Reserve in the Refuse Fund, as reported in the Adopted Operating
Budget, currently has a negative balance. This negative balance is attributable to
liabilities associated with maintaining the closed landfill, as mandated by Public
Resources Code and the California Code of Regulations. As revenues are realized
and maintenance activities are completed, the liabilities will be reduced and the
Rate Stabilization Reserve negative balance will become positive. While the Rate
Stabilization Reserve reflects a negative balance, it is important to note that there
is sufficient cash in the fund to cover operations and the cost of the kitchen pails,
outreach and education, and advertising costs recommended to be appropriated
in FY 2015 pending eventual City Council approval of a Budget Amendment
Ordinance for these items in the amount of $387,000.
Residential Food Scraps Collection Program Costs
Implemening a new residential food scraps collection program will cost
approximately $1,134,000 per year, beginning in FY2016. This is equivalent to an
approximate 6% rate increase for residential customers with 32-gallon garbage
cart service or an average monthly increase of approximately $2.52 per month for
all residential customers. This cost is incorporated into the residential rate tables
earlier in the report and projected rate increases will be brought forward for
Council consideration as part of the FY 2016 budget process.
An initial investment of $387,000 will be needed in FY 2015 to purchase kitchen
pails and provide the outreach and training materials needed for this new
program’s implementation. Outreach and training materials will include cart tags,
program brochures, stickers for collection carts, stickers for the kitchen pails,
how-to video, and informational postcards with program information.
Community meetings will be held to orient the public at the beginning of the roll-
out of this new program. At a later date it is anticipated that Staff will bring
forward for City Council approval a Budget Amendment Ordinance for the Refuse
City of Palo Alto Page 23
Fund in the amount of $387,000, to be offset by a reduction to the ending fund
balance in order that the City may fund this outreach prior to FY 2016.
One-Time FY 2015 Costs – Residential Food Scraps Collection Program
Item One Time Costs
Purchase kitchen pails for each residence (18,000 at $6.00
per bucket) $108,000
Outreach and training materials design, development,
printing and distribution costs $239,000
Print and online ads and other advertisement costs $40,000
Total One Time Costs $387,000
Policy Implications
The collection of food scraps is consistent with the City’s Zero Waste Operational
Plan and Climate Protection Plan both adopted in 2007 to provide for the
collection and diversion of all compostable materials.
The increased discount for commercial compostable service will help the City
achieve its zero waste goals by 2021.
Environmental Review
GHG Savings
Diverting and composting the expected recoverable amount of 10,000 tons of
residential and commercial food scraps per year would save over 3,800 metric
tons of CO2e emissions per year that contribute to global climate change.
CEQA
Collecting residential food scraps within the existing green carts and composting
this material is consistent with the baseline three cart collection services that was
studied in the Initial Study-Mitigated Negative Declaration adopted by Council
with the GreenWaste Contract award in 2008 (CMR 416:08). In addition, this new
food scraps program is designed to reduce the impacts to the environment by
reducing the amount of greenhouse gas generated and by maximizing the
recovery of compostable materials generated within the City.
City of Palo Alto Page 24
There will be negligible transportation related impacts from modifications to
existing compostable collection routes.
