IMPLEMENT GENERATORS ON A CASE BY CASE BASIS FOR
STORMWATER PUMP STATIONS.
WHEREAS, the City of Miami Beach is committed to its flood mitigation program and to
integrating resilience in all aspects of its infrastructure; and
WHEREAS, one of the most important aspects of the flood mitigation program are
effective pump stations that properly treat and convey the stormwater, and one of the most
important aspects of the program's resilience is the ability to maintain power for these pump
stations through shocks and stresses; and
WHEREAS, on Aug 1st, 2017, during Tropical Storm Emily, power outages affected the
operations of certain pump stations, including the pump stations located at Sunset Harbour, and
as a result of these outages the City experienced significant flooding in parts of the Sunset
Harbour neighborhood; and
WHEREAS, this flooding related to Tropical Storm Emily was a catalyst for a City
Commission discussion on implementing emergency generators at every stormwater pump
station throughout the City; and
WHEREAS, at the September 13, 2017 City Commission meeting, it was resolved that
all new stormwater pump stations would require a backup generator; and
WHEREAS, in accordance with the City Commission's directive, the Public Works
Department has ensured that all design criteria for future projects includes the provision of
permanent generators at each pump station location; and
WHEREAS, while permanent generators are an excellent way to provide redundancy to
the stormwater system, they often require additional engineering, site planning, aesthetic
improvements, and community involvement; and
WHEREAS, residents that live in neighborhoods with proposed generators have, at
times, expressed concerns related to their aesthetics, noise levels, and maintenance operations;
and
WHEREAS, this has been the case with neighborhood projects such as West Avenue
and the First Street projects; and
WHEREAS,while the City is committed to resilience—and redundant power supplies are
a key component of resilience—the City is also keenly interested in placemaking and enhancing

stormwater pump stations as critical infrastructure; and
WHEREAS, in cases where FPL categorizes a pump station as critical infrastructure, the
stations would include dual primary feeds from independent substations with automatic transfer
switches; and
WHEREAS, by utilizing this configuration, if one of the electrical feeds is rendered in
operable, the other primary feed would automatically supply power without interruption to the
pump station; and
WHEREAS, pump stations categorized by FPL as critical infrastructure would be
reviewed by FPL and the City's Public Works Department during a project's planning and design
stage; and
WHEREAS, in cases where FPL is able to provide dual primary feeds to a pump station,
substantial electrical redundancy will be provided to the pump station, and thus, a backup
generator may not be required; and
WHEREAS, future projects may benefit from a cost and community impact perspective if
backup generators are implemented on a case by case basis.
NOW, THEREFORE, BE IT RESOLVED BY THE MAYOR AND CITY COMMISSION
OF THE CITY OF MIAMI BEACH, FLORIDA, hereby, accept the recommendation of the
September 22, 2020 Land Use and Sustainability Committee, to implement generators on a case

COMMISSION MEMORANDUM
TO: Honorable Mayor and Members of the City Commission
FROM: Jimmy L. Morales, City Manager
DATE: October 14, 2020
SUBJECT:A RESOLUTION OF THE MAYOR AND CITY COMMISSION OF THE CITY
OF MIAMI BEACH, FLORIDA, ACCEPTING THE RECOMMENDATION OF
THE SEPTEMBER 22, 2020 LAND USE AND SUSTAINABILITY
COMMITTEE, TO IMPLEMENT GENERATORS ON A CASE BY CASE
BASIS FOR STORMWATER PUMP STATIONS.
RECOMMENDATION
The Administration recommends that the Commission adopt the Resolution approving the
implementation of emergency generators for stormwater pump stations on a case by case
basis.
BACKGROUND/HISTORY
The City of Miami Beach is committed to its flood mitigation program and to integrating
resilience in all aspects of its infrastructure. One of the most important aspects of the flood
mitigation program are effective pump stations that properly treat and convey the stormwater.
Thus, by definition, one of the most important aspects of the program's resilience is the ability to
maintain the electrical service for these pump stations through shocks and stresses.
On Aug 1st, 2017, during Tropical Storm Emily, power outages affected the operations of
certain pump stations, including the pump stations located at Sunset Harbour. As a result of
these outages the City experienced significant flooding in the Sunset Harbour community.
This flooding precipitated a Commission discussion on implementing emergency generators at
every storm water pump station throughout the City. At the September 13, 2017 which was
continue to September 25, 2017 City Commission meeting, during a discussion item, it was
recommended that all new stormwater pump stations would include backup power generators.
Following suit, the Public Works Department ensured all design criteria for future projects
include the provision of permanent generators at each pump station location.
ANALYSIS
While permanent generators are an excellent way to provide redundancy to the stormwater
system, they often require additional engineering, site planning, aesthetic improvements, and
community involvement. Residents that live in neighborhoods with proposed generators have, at
times, expressed concerns related to their aesthetics, noise levels, and maintenance
Page 1097 of 1576
operations. This has been the case with critical neighborhood projects such as West Avenue
and the First Street projects.
While the City is committed to resilience, and redundant power supplies are a key component
of resilience, the City is also keenly interested in placemaking and enhancing neighborhood
aesthetics. Fortunately, recent conversations with Florida Power and Light (FPL), the primary
electric power supplier for the pump station, have revealed that the City may be able to establish
electrical redundancy in the future without the use of backup generators.
On August 18, 2020, FPL agreed to potentially categorize the City's stomiwater pump stations
as critical infrastructure. In cases where FPL categorizes the pump station as critical
infrastructure, the stations would include dual primary feeds from independent substations with
automatic transfer switches. By utilizing this configuration, if one of the electrical feeds is
rendered in operable, the other primary feed would automatically supply power without
interruption to the pump station.
These pump stations would be reviewed by FPL and the City's Public Works Department
during a project's planning and design stage. In cases where FPL is able to provide dual
primary feeds to a pump station, substantial electrical redundancy will be provided to the pump
station. Thus, a backup generator may not be required.
Future projects may benefit from a cost and community impact perspective if backup
generators are implemented on a case by case basis.
CONCLUSION
The Administration recommends that the Commission adopt the Resolution approving the
implementation of emergency generators for stormwater pump stations on a case by case
basis.

Roy Coley, Public Works Director, presented this item. He reported most of the data collected
thus far has been driven by complaints or staff observation and currently there is no true analytical
method that collects flooding events. In order to obtain this kind of data, he recommended to
install observation tools in order to be able to correlate what the water levels are with the various
conditions to determine if flooding is related to rain or tidal influence. City staff will continue to
work with consultants to develop a scope, cost of the project, and bring back to the committee for
consideration.
Commissioner Samuelian clarified he is requesting analytical data going forward that can help
understand the nature and frequency of flooding throughout the city.

Office of Capital Improvement Projects
AFTER-ACTION:
Commissioner Mark Samuelian introduced this item. He stated there are issues with the streets
along the Venetian Islands and the residents have communicated that they would like to see the
street projects completed.
David Martinez, Capital Improvement Projects Director, presented this item. City administration
placed an item on this subject on the February 2020 City Commission agenda and withdrew it at
the request of the Venetian Islands Homeowner's Association to further discuss the potential
options and review Jacobs' recommendations. City staff has met with the homeowner's
association and identified several options to complete the asphalt project and is recommending
option 2. Mr. Martinez summarized the repair methodology of option 2.
Commissioner Samuelian asked what the current elevations are and for the city's
recommendations as it relates to road elevation requirements. Mr. Martinez stated some of the
islands, specifically San Marino Island, has elevations as low as one-foot NAVD. He explained
that this project began development before the city embarked on road raising and other robust
Page 1104 of 1576
Report of the Land Use&Sustainability Committee Meeting of September 22,2020
Page 6 of 9
stormwater pumping systems.The project was under construction with a more traditional system
of stormwater management and was evaluated on whether the new techniques could be
applicable to this project. Due to how advanced it was in construction, road elevation was not
possible. He suspects road elevation would be considered if this project was starting today.
Melissa Beattie, President of the Venetian Islands Homeowners Association, expressed the
homeowner's association is in favor of option 2.
Commissioner Samuelian asked for an estimate on when the project will begin and finish. Mr.
Martinez stated a resolution supporting option 2 is needed from the committee for clarity on the
means and methods of finalizing the project. He stated there are contracts currently in place and
that they have obtained estimates to have a different contractor perform this work. He stated he
will give an update at the next coomission meeting on the progress city staff and the City Attorney's
office has made regarding the current contractor's agreement.
MOTION: By acclamation. (11:14 AM)
Staff to bring resolution to full Commission in support of option 2 with the direction to
encourage city administration and the City's Attorney's office to start working on finalizing
the plan and begin work as soon as possible.

Office of the City Attorney
Updated September 17, 2020
AFTER-ACTION:
Aleksandr Boksner,Chief Deputy City Attorney, presented this item. The proposed ordinance
creates a new provision under new section 142-3 of the city code to prohibit future business
entities and future person from renting or leasing of certain identifiable vehicles. The proposed
ordinance would allow those businesses that currently rent or lease these identifiable vehicles to
continue to legally operate.
Members of the public addressed the committee (Irene Bigger, Daniel Ciraldo, Paula King, and
Tim Karr).
Daniel Cirado, Miami Design Preservation League, asked if Bird e-scooters are allowed on the
city's right of ways. Mr. Boksner stated he will research if the city is within the legal right to prohibit
Bird e-scooters from being rented.
Commissioner Steven Meiner stated he is working with the City Attorney's Office to develop a
supplemental ordinance to enforce requirements onto the businesses that rent or lease these
vehicles and present it to full commission.
Commissioner Michael Gongora asked if the Planning Board is hearing this item today, as well.
Mr. Boksner reported the Planning Board is meeting today and he will be presenting this item at
the Planning Board at a later hour. Tom Mooney, Planning Director stated, this item will be heard
again at the October 27, 2020 Planning Board meeting to continue further discuss.
Commissioner Gongora asked if the scooter ordinances penalize scooter operators that bring
their scooters from outside of Miami Beach and participating in illegal behavior. Mr. Boksner stated
the city does not have legal authority to penalize scooter businesses outside of Miami Beach's
jurisdiction, but the city can penalize the operator for illegal behavior. Commissioner Gongora
wants the ordinances to enhance the penalties against operators. Mr. Boksner stated the city
does not have the legal authority to go beyond what is set forth in Chapter 216 but will research
further if further penalties can be enforced.
Commissioner Ricky Arriola requested for greater enforcement on the scooter operators. He
suggested this might be an opportunity to phase the businesses into renting more electric
scooters and phasing out the gas scooters.
Commissioner Mark Samuelian agreed that stronger enforcement is needed.
Commissioner Arriola asked to amend the ordinance to include a provision for a one year look
back to see if there has been any identifiable impact. He also requested to amend the ordinance
to exempt new businesses that only rent or lease electric scooters. Commissioner Samuelian
stated that can be discussed at Commission but wants to continue with the current proposed
ordinance as is with the two amendments of enforcement and a one year look back.
Commissioner Gongora recommended to mandate the current businesses to be the only scooter
Page 1106 of 1576
Report of the Land Use&Sustainability Committee Meeting of September 22, 2020
Page 8 of 9
businesses within the city but are required to segway and convert all scooters to electric within
three years. Mr. Boksner expressed he is unsure if this proposal is appropriate at this time given
the legal challenges it may bring on and recommended moving forward with the proposed
ordinance and two amendments and investigate Commissioner Gongora's suggestion in the
future. He stated this item will be brought to full commission for first reading in November.
Commissioner Gongora asked if his suggestion can be added to the motion and brought to and
voted by the Planning Board in October.
Commissioner Samuelian asked to be included as co-sponsor to this item.
MOTION: By acclamation. (8:42 AM)
- Staff to amend item to include gradual elimination of non- electric scooters from
scooter businesses at the October Planning Board meeting.
- Staff to bring item to City Commission for 1$' Reading as amended:
o Staff to bring ordinance back to commission after one year for evaluation
regarding its effectiveness.

20. Discuss, And Take Action If Necessary, Whether Miami Beach Should Mandate The
Installation Of A Generator For All Stormwater Projects.As Is Currently The Case,And Instead
Review On A Case-By-Case Basis, Based On A Recent.Commitment From Florida Power And
Light(FPL)To Supply Multiple Electrical Sources To Miami Beach Stormwater Pump Stations
As They Are Designated Essential Infrastructure.
Commissioner Steven Meiner
September 16, 2020 R9 N
Public Works
Updated September 17, 2020
AFTER-ACTION:
Commissioner Steven Meiner introduced the item. He stated the current mandate is to install
generator for all stormwater pump stations. Florida Power and Light (FPL) has committed to
supplying multiple electrical sources to the city's stormwater pump stations because they are
designated essential infrastructure.The generators will be then deemed redundant;therefore,the
mandate should be amended to install generators on a case-by-case basis.
Roy Coley, Public Works Director, stated built in generators were not included in the original
stormwater program, however, in September 2017, there was a Commission discussion item on
this topic that led to a Letter to Commission committing to including generators at all future designs.
There has been both positive and negative feedback on the presence of generators over the years.
Recently, city administration met with FPL, in which they committed to treating stormwater pump
stations as a critical infrastructure component and can supply multiple power sources to the pump
stations in the case that power is lost in order to minimize risk.
Members of the public addressed the committee (Keith Marks and Paula King).
Paula King asked if there are alternative power sources other than FPL that could supply power.
Mr. Coley explained city staff have explored several technologies and found that they are not
feasible. They continue to ask their consultant to find alternatives to reduce the dependence on
engine powered electricity and no other solutions have been found. City staff has had ongoing
Page 1107 of 1576
Report of the Land Use&Sustainability Committee Meeting of September 22,2020
Page 9 of 9
discussions with FPL that has led to FPL committing to providing multiple power sources as an
interim step to reducing alternate power needs while staff looks for more technology.
Commissioner Gongora expressed approval of this item and asked what the next steps are. Mr.
Coley stated staff will return to commission with a resolution specifically stating future projects will
be looked at on a case-by-case basis and eliminate the current plan of generators at every project.
Commissioner Samuelian requested to be added as co-sponsor to resolution.
MOTION: By acclamation. (8:58 AM)
Staff to bring resolution to full Commission specifically stating installation of generators
for future stormwater projects will be looked at on a case-by-case basis and eliminate the
current plan of requiring generators for every project.
The meeting.adjourned at 11:50 AM.

COMMISSION MEMORANDUM
TO: Honorable Mayor and Members of the City Commission
FROM: Jimmy L.Morales,City Manager
DATE: September 13,2017
SUBJECT: DISCUSSION REGARDING THE INSTALLATION OF PERMANENT GENERATORS AT STORMWATER PUMP
STATIONS THROUGHOUT THE CITY.
RECOMMENDATION
The Public Works Department is recommending that all future storm water pumping stations are to include a permanently mounted
generator capable of powering the entire station unless an extreme condition exists preventing the inclusion. All existing storm
water pumping stations should be individually reviewed for space requirements, and other logistics to determine whether a retrofit
is appropriate.
ANALYSIS
The expected cost to redesign, and construct the city's stormwater system is expected to be approximately$500 million and every
effort has been taken to limit the expenses. A significant component of limiting expenses was the decision to rely on portable
generators verses permanently mounted generators at the pumping station. The cost of built in permanently mounted generators
begins at over $400,000 each, and increases based on the size of the pumping station. The system is likely to have 80 to 85
pumping station at completion.The total cost to have permanently mounted generators was estimated to be over$32 million.
Other factors contributed to the decision making process to rely on portable generators to supply power during outages, Financial
factors were important, however, non-financial factors were important to consider also.The most noteworthy were aesthetics, and
the likelihood of power failure.
Aesthetic considerations were important to various stakeholders from the very beginning stages of designing the modem
stormwater pumping stations. Most of the pumping components are located underground, and out of sight. The control centers
must be located 2 feet above base flood elevation, and close in proximity to the pumping equipment.The control centers include
electrical service panels, elevated platforms, and stairs. The aesthetics were such a priority that in many locations the platforms
and stairs have been eliminated from the control centers requiring operations and maintenance to be performed from portable
ladders.
Diesel powered generators capable of powering the city's stormwater pumping station are aesthetically challenging.They are about
the size of an automobile at the smaller pumping stations, and the size of a truck at the larger stations. Permanently mounted
generators must also be located 2 feet above the base flood elevation which is often 5, or more, feet aboveground. In some
locations landscaping could be used to reduce the view of the equipment, and in other locations space limitations would only allow
for some type of screening.
Florida Power and Light classified the city's stormwater pumping stations as critical infrastructure, and placed them on its most
robust power supplies. Unplanned outages were considered to be unlikely,or very infrequent.Planned outages,such as power grid
shutdowns caused by tropical weather, came with enough advance warning to deploy portable generators timely. The risk of not
having permanently mounted generators was considered acceptable.
In October 2016 the impacts of Hurricane Matthew prompted a review of the city's tolerance for risk concerning generators.
Ultimately that review resulted in Public Work being directed by the Mayor and Commission in February 2017 to begin procurement
of permanently mounted generators for the Sunset Harbour neighborhood's pumping stations number 2 and 3. August 1, 2017
produced an extreme weather event that prompted the issuance of an emergency authorization to accelerate the procurement of
the Sunset Harbour generators, and to develop recommendations for other stormwater pumping stations.
CONCLUSION
The Public Works Department is recommending that all future storm water pumping stations are to include a permanently mounted
generator capable of powering the entire station unless an extreme condition exists preventing the inclusion. All existing storm
water pumping stations should be individually reviewed for space requirements, and other logistics to determine whether a retrofit
is appropriate. Some consideration was given, but ultimately rejected, to the possibility of supplying only 50% of the individual
station's pumps to reduce generator sizing and cost.Various stakeholders have been consulted to measure their risk tolerance for
not having permanently mounted generators, verses their tolerance for the less attractiveness of having them. There seems to
have been a substantial change in the community's willingness to have more unattractive equipment in view to reduce the risk of
flooding.

ACTION: Discussion held. Item heard in conjunction with R9 AB. Motion by Commissioner Aleman to
give direction to staff to look into dual fuel and battery-powered generators; seconded by
Commissioner Malakoff. Voice vote: 6-0. Absent: Commissioner Grieco. Eric Carpenter to handle.
Eric Carpenter, Assistant City Manager/ Public Works Director, introduced the item that refers to the
installation of permanent generators throughout Miami Beach. These generators would be used to
power the various City pumps while the power is down. Currently, the City uses mobile generators,
but the permanent ones would better suit the City's needs in emergencies.
Commissioner Aleman asked whether there is a preference for natural gas, diesel, or dual fuel
generators.
Mr. Carpenter explained the difference between the various generators.
Mayor Levine asked about the viability of the Tesla "power packs."
Mr. Carpenter stated that they are currently looking into this option, and have reached out to Tesla.
Commissioner Malakoff expressed her concern over the loudness and imposing presence of the
generators. The City's aesthetics may be compromised.
Mr. Carpenter added that in addition to Commissioner Malakoff's comments, the generators also
require weekly check-ups and monthly engine runnings to make sure they are operating correctly.

Continued September 18&25, 2017
Mayor Levine stated that it is a difficult task to keep Miami Beach dry, and it may involve having large
generators throughout the City, and weekly loud tests; but if that is what it takes, he believes the City
should go ahead with it.
Discussion continued regarding dual fuel generators.
Commissioner Rosen Gonzalez stated that the City needs to have better alternate plans before
spending the enormous $40 million for the fixed generators. She believes an REP should be issued
to gather the best minds in the world to help decide what to do.
Vice-Mayor Arriola agreed that this project will cost a large amount of money, but the City needs an
uninterrupted source of power for its generators. If there is another and cheaper solution, he would
like to hear it.
Mayor Levine stated that resiliency efforts have cost half a billion dollars. Without power, the pumps
will not work. There needs to be an energy source for when the power is cut off.
Commissioner Steinberg appreciates the message the Mayor is conveying, but she believes the
residents of Miami Beach are unaware of the sheer size of the generators. The pumps they will be
powering are only one-third of their size.
Commissioner Aleman directed staff to study the dual fuel generators and make a recommendation.
Commissioner Steinberg also gave direction to look into battery-powered generators to better discuss
all options.
3:21:07 p.m.
Commissioner Rosen Gonzalez changed her vote to a yes.

NO. LTC # 219-2018 LETT R TO COMMISSION
TO: mayor uan ueioer and Members o the City Co mission
FROM: Jimmy L. Morales, City Manager
DATE: April 23, 2018
SUBJECT: Generators at Stormwater Pump S tions
The purpose of this Letter to Commission is to provide information to the Mayor and City
Commission regarding generators at stormwater pump stations.
As you are aware, the Urban Land Institute Advisory Services Panel reviewed the process of
the City of Miami Beach's Stormwater Management Program last week and provided advice on
a wide variety of elements associated with our program and our approach to mitigating flooding
caused by tidal and rain events. Included in their preliminary finding was the issue of a reliable
source of power to the pumps.
We realize that residents and property owners have concerns as to the availability of auxiliary
electrical power to stormwater pump stations, in the event of power interruption. The City is
actively addressing their concerns.
All design criteria for future projects, including those currently in the procurement process,
include the provision of permanent generators at each pump station location. Projects included
are La Gorce and Indian Creek. For projects that are currently under contract, City
Administration has requested proposals for the provision of permanent generators. These
include Palm & Hibiscus Islands, West Avenue, Sunset Islands 3 & 4, Central Bayshore South
and Venetian Islands (San Marino, DiLido and Rivo Alto). In addition, the Administration is
considering retrofitting existing stormwater pumping stations.
There are numerous challenges to consider in the installation of permanent generators. A
significant component is the cost associated with the installation. Depending on the size and
capacity of each pump station, these installations can range from $400,000 to $800,000.
Another limiting factor is the placement of this large industrial piece of equipment. The size of
the permanent generators is considerable. Diesel powered generators are about the size of an
automobile for the smaller pump stations, and the size of a shipping container for the larger
stations (see attached). Accessibility for maintenance and fueling is another factor to consider in
the location. Elevation for flood protection must also be taken into account. Permanently
mounted generators must be located two (2) feet above the base flood elevation which is often
five (5), or more, feet aboveground. Aesthetics is another factor that must be taken into
consideration. In some locations, landscaping could be used to reduce the view of the
equipment, and in other locations space limitations would only allow for minimum type of
screening.
In the interim, the City has been and will continue to place temporary portable generators at
existing pump station locations, as warranted. Recently installed pump stations are equipped
with generator receptacles to allow for operations with portable generators.
Should you have any questions, please contact Eric Carpenter at 305-673-7080.
