Disclaimer
• The results presented in this document should not be treated or
interpreted as final; as an estimate is used for the amount of illegal
trash being collected due to limited data available at the time of the
review. The tracking of illegal trash tonnage however has begun
• The results of this document reflect the Department's current state
• The scope of work does not formally include a comprehensive
analysis for setting a trash pickup fee only and/or reviewing the
existing $380 fee for garbage and trash pickup service
Illegal Trash - Definition
• Definition of illegal residential trash for this study:
• Trash dumped by the residents of the City of Miami who do not pay for it or
do not comply with the City Code
• Trash that originates from the City of Miami residential building, but dumped
by a contractor
• The fact that illegal trash is found and collected in residential areas
does not mean that it originates in the City of Miami
• Illegal trash is not considered significant in the 51+ unit buildings
Illegal Trash - Findings
• The current 10,000 tons is an estimate
• Recently started collecting illegal trash data
• Not all the illegal trash volume will go down
• According to the City of Miami Police about 58% is related to residential
buildings. The other 42% is related to trash coming outside of the City of
Miami
• There is a maximum reduction of 47% expected since some residents will still
not comply with the code
• Illegal trash is already being collected in the As -Is situation and is currently
included in the 1-3 unit buildings tonnage numbers
• Reduction in illegal trash will not reduce trash volume as it will become legal
trash when service is provided to buildings in the respective scenarios
Outsourcing — Price Estimates
• Third party vendors were contacted to obtain price estimates based
on projected volumes and units related to each scenario
• 10 commercial haulers were contacted
• Commercial haulers were briefed on what was needed to obtain a
price estimate
• One quote: $420 per unit including disposal and franchise fees
• Only one quote was received
• No formal RFP process was conducted
• Vendors did not have the capacity to undertake the expected operation
Outsourcing - Challenges
• Two trash picking operators working on the same routes is not
recommended due to:
• Logistical challenges related to scheduling
• Legal challenges related to who picks up illegal trash
• Lack of economies of scale resulting in a higher cost per unit
• If pickup service for additional units is outsourced, the Solid Waste
trash pickup operation will have to be downsized. Currently Solid
Waste is already picking up trash from the additional units as illegal
trash. Therefore, this volume will be lost to the 3rd party
• These two statements are specifically applicable to the 4-12 and 13-
50-unit buildings

RISK & PRODUCTIVITY
For 51+ unit buildings there is a higher risk as the pick-up
method, roll -off or manual, will be different from the
current main method.
Adding 4-12 and 13-50 unit buildings will increase the
productivity due similar routes, better use of existing
equipment and people.

ILLEGAL TRASH & FINANCIAL
Projection of financial results is based on the
assumption that the extra units will be charged the new
average cost per unit per year associated with each
scenario.
There is currently no illegal trash issue with 51+ unit
buildings. Change of trash pick up service there could
result in more illegal trash

Assumptions: General (1)
Trash pickup once a week for all scenarios
Rounding up to 1 full FTE when it comes to
hiring People
Extrapolation of depreciation expenses as the
type of investments will depend on the pickup
method
14
Assumptions: General (2)
A markup of 10% for unforeseen expenditures
is added
Equipment expected to be used for 12 years
Inflation set at 3%
15
Assumptions: Illegal Trash
• Illegal dumping is proportionally distributed between
4-12 unit and 13-50 unit buildings based on the
number of units
• Reduction due to illegal dumping already picked up
will have the same breakdown by Regular/Green as it
is now
• The reduction in citations revenue will mirror the
reduction in illegal trash
i[LEGiti.
SUMPING
Assumptions: 4-12 and 13-50 unit buildings
• Pickup method the same as -is
• For the 4-12 and 13-50 unit buildings it is expected that
existing assets can be mostly used.
• Some new investments required. Percentage of regular
depreciation: 70%
• Mini dump volume will not be substantially impacted
Assumptions: 51+ unit buildings
• Pickup method for 51+ unit buildings will either be Roll -Off
containers OR manual
• 104 buildings with 51-100 units 4 manual
• 106 buildings with 101+ units 4 roll -off containers
• Manual
• Crew of 3 persons
• 3.5 buildings per crew per day. 17.5 per week
• 6 crews needed. 8 crews with vacation and sickness
• Roll -off
• J. driver
• 6.5 containers per 10 hrs. working day. 26 per week
• 4 drivers needed. 6 drivers with vacation and sickness
• 2 extra dispatchers needed in the back office
• Currently a 50/50 breakdown of buildings is expected between
manual and roll -off containers
• Substantial investments required. Percentage of regular
depreciation: 125%
• New software is required: cost/year estimated at $50k

• Next Steps
Disclaimer
• The results presented in this document should not be treated or
interpreted as final; as an estimate is used for the amount of illegal
trash being collected due to limited data available at the time of the
review. The tracking of illegal trash tonnage however has begun
• The results of this document reflect the Department's current state
• The scope of work does not formally include a comprehensive
analysis for setting a trash pickup fee only and/or reviewing the
existing $380 fee for garbage and trash pickup service
Illegal Trash - Definition
• Definition of illegal residential trash for this study:
• Trash dumped by the residents of the City of Miami who do not pay for it or
do not comply with the City Code
• Trash that originates from the City of Miami residential building, but dumped
by a contractor
• The fact that illegal trash is found and collected in residential areas
does not mean that it originates in the City of Miami
• Illegal trash is not considered significant in the 51+ unit buildings
Illegal Trash - Findings
• The current 10,000 tons is an estimate
• Recently started collecting illegal trash data
• Not all the illegal trash volume will go down
• According to the City of Miami Police about 58% is related to residential
buildings. The other 42% is related to trash coming outside of the City of
Miami
• There is a maximum reduction of 47% expected since some residents will still
not comply with the code
• Illegal trash is already being collected in the As -Is situation and is currently
included in the 1-3 unit buildings tonnage numbers
• Reduction in illegal trash will not reduce trash volume as it will become legal
trash when service is provided to buildings in the respective scenarios
Outsourcing — Price Estimates
• Third party vendors were contacted to obtain price estimates based
on projected volumes and units related to each scenario
• 10 commercial haulers were contacted
• Commercial haulers were briefed on what was needed to obtain a
price estimate
• One quote: $420 per unit including disposal and franchise fees
• Only one quote was received
• No formal RFP process was conducted
• Vendors did not have the capacity to undertake the expected operation
Outsourcing - Challenges
• Two trash picking operators working on the same routes is not
recommended due to:
• Logistical challenges related to scheduling
• Legal challenges related to who picks up illegal trash
• Lack of economies of scale resulting in a higher cost per unit
• If pickup service for additional units is outsourced, the Solid Waste
trash pickup operation will have to be downsized. Currently Solid
Waste is already picking up trash from the additional units as illegal
trash. Therefore, this volume will be lost to the 3rd party
• These two statements are specifically applicable to the 4-12 and 13-
50-unit buildings

SCENARIOS
RISK & PRODUCTIVITY
For 51+ unit buildings there is a higher risk as the pick-up
method, roll -off or manual, will be different from the
current main method.
Adding 4-12 and 13-50 unit buildings will increase the
productivity due similar routes, better use of existing
equipment and people.

ILLEGAL TRASH & FINANCIAL
Projection of financial results is based on the
assumption that the extra units will be charged the new
average cost per unit per year associated with each
scenario.
There is currently no illegal trash issue with 51+ unit
buildings. Change of trash pick up service there could
result in more illegal trash
