10-Year Water Supply Facilities Work Plan Update
1.0 INTRODUCTION
The purpose of the City of Miami Water Supply Facilities Work Plan (Work Plan) is to
identify and plan for the water supply sources and facilities needed to serve existing
and new development within the City's jurisdiction. Chapter 163.3177(6)(c)3, Part II,
F.S., requires local governments to prepare and adopt Work Plans into their
comprehensive plans within 18 months after the water management district
approves a regional water supply plan or its update. The Lower East Coast Water
Supply Plan Update was previously approved by the South Florida Water
Management District (SFWMD) Governing Board on Fcbruary 15, 2007 November
8, 2018 while Miami -Dade County's 10-Year Water Supply Facilities Work Plan
Update was adopted April 2022 and corresponding CDMP Text Amendments
adopted on January 19, 2023. The City last adopted a 20 Year Water Supply
Facilities Work Plan Update April 22, 2010 on September 10, 2015. This Work Plan
Update will be adopted with a 210-year planning horizon to be consistent with both
the Miami -Dade County and South Florida Water Management District Water
Facilities Work Plans. TThe SF\\NMD governing Board su bsegu ently approved an

The City of Miami has recognized the importance of water conservation through the
Miami Comprehensive Neighborhood Plan (MCNP). The City recognizes that in
order to maintain a proactive water conservation program there has to be an
effective coordination program with Miami -Dade County Water and Sewer
Department (MDWASD) to ensure the success of the program. In addition, the City
maintains an excellent working relationship with WASD as a retail customer to
ensure compliance with all applicable regulations and guidelines.
The City of Miami is one of 15 municipal "retail" customers. Rcsidcnts Potable Water
users within the City receive 100% of it& all potable water directly from the Miami -
Dade County Water and Sewer Department (MDWASD), which is responsible for
ensuring that enough capacity is available for existing and future customers. Under
this arrangement, the City will coordinate& with MDWASD to ensure that enough
capacity is available for existing and future customers and supporting infrastructure.
The Updated City of Miami Water Supply Facilities Work Plan (Work Plan) will reflect
whatcver any changes in the regional plan affecting its local water supply and work
plan. In addition, since the City is a retail der customer, it will reference the
initiatives already identified in Miami -Dade County's 210-year Work Plan. According
to state guidelines, the Work Plan and the comprehensive plan amendment must
address the development of traditional and alternative water supplies, bulk sales
agreements and conservation and reuse programs that are necessary to serve
existing and new development for at least a 10-year planning period. The City of

Miami Work Plan will have the same planning time schedule as the most recently
approved Miami -Dade County's 210-year Work Plan.
Southeast Florida is one of the most vulnerable regions to the impacts of climate
change and sea level rise and is expected to present significant challenges related
to water resource planning, management and infrastructure. Mitigation and adaption
strategies are also addressed herein as a primary focal arca.
The information amendments contained within this Work Plan Update will be
included amendments t„ in the various elements of the City's Comprehensive
Plan.
The City's Work Plan is divided into six sections:
Section 1 — Introduction
Section 2 — Background Information
Section 3 — Data and Analysis
Section 4 — Intergovernmental Coordination
Section 4 5 — Work Plan Projects/Capital Improvement Element/Schedule
Section 5 6— Climate Change and Sea Level Rise
Section .57— Goals, Objectives, Policies
1.1 Statutory History
The Florida Legislature enacted bills in the 2002, 2004, a-r4 2005, 2011, 2012, 2015
and 2016 sessions to address the state's water supply needs. These bills,
especially Senate Bills 360 and 444 (2005 legislative session), significantly changed
Chapter 163 and 373 Florida Statutes (F.S.) by strengthening the statutory links
between the regional water supply plans prepared by the water management
districts and the comprehensive plans prepared by local governments. In addition,
these bills established the basis for improving coordination between the local land
use planning and water supply planning.
In 2005, lawmakers revised state water law, Section 373.707, F.S., and created the
Water Resource Protection and Sustainability Program, which requires a higher level
of water supply planning coordination between water management districts and local
governments.
Effective July 1, 2010, the Florida legislature passed an amendment to Section
373.707, F.S., which concerns water management district funding of alternative
water supply projects. The legislation added "water conservation projects that result
in quantifiable water savings" to those projects eligible for funding,
In 2011, the Florida Legislature updated Chapter 163, Part II, F.S., to include The
Community Planning Act (163.3164, F.S.), which addresses the state's water supply
needs. The Act requires each municipality and county to adopt and maintain a
comprehensive plan. In Florida, all proposed and approved development in the

10-Year Water Supply Facilities Work Plan Update
community must be consistent with the comprehensive plan. In terms of water
supply planning, information about state requirements for local government
comprehensive plans is available in each regional water supply plan update.
As of June 2012, 90 percent of all local governments within the SFWMD developed
and formally submitted their Water Supply Facilities Work Plans. The development
of these plans has assisted the SFWMD in coordinating future water supply planning
and permitting with local government land use planning.
The 2012, 2015 and 2016 Statute changes clarified certain language which does not
materially impact the City of Miami
1.2 Statutory Requirements
In order to meet water supply and water facilities planning requirements, local
government comprehensive plans must address the following:
1. Coordinate appropriate aspects of their comprehensive plan with the
appropriate water management district's regional water supply plan. [Section

2. Ensure that its future land use plan is based upon availability of adequate
water supplies and public facilities and services [s.163.3177(6)(a), F.S.].
Data and analysis demonstrating that adequate water supplies and
associated public facilities will be available to meet projected growth demands
must accompany all proposed Future Land Use Map amendments submitted
for review.
3. Ensure that adequate water supplies and facilities are available to serve new
development no later than the issuance by the local government of a
certificate of occupancy or its functional equivalent and consult with the
applicable water supplier to determine whether adequate water supplies will
be available to serve the development by the anticipated issuance date of the
certificate of occupancy [s.163.3180 (2)(a), F.S.].
4. For local governments subject to a regional water supply plan, revise the
General Sanitary Sewer, Solid Waste, Drainage, Potable Water, and Natural
Groundwater Aquifer Recharge Element (the "Infrastructure Element"), within
18 months after the water management district approves an updated regional
water supply plan, to:
a. Identify and incorporate the alternative water supply project(s) selected
by the local government from projects identified in the updated SFWMD
Regional Water Supply Plan or the alternative project(s) proposed by the local
government under s. 373.709(8)(b), F.S. fs. 163.3177(6)(c), F.S.1;
b. Identify the traditional and alternative water supply projects, and the
conservation and reuse programs necessary to meet water needs identified in
the SFWMD Regional Water Supply Plan [s. 163.3177(6)(c), F.S.]; and,
c. Update the Work Plan for at least a 10-year planning period for
constructing the public, private, and regional water supply facilities identified

in the element as necessary to serve existing and new development. [s.
163.3177(6)(c), F.S.].
5. Revise the Five -Year Schedule of Capital Improvements to include water
supply, reuse, and conservation projects and programs to be implemented
during the five-year period [s. 163.3177(3)(a)4, F.S.1.
6. To the extent necessary to maintain internal consistency after making
changes described in Paragraph 1 through 5 above, revise the Conservation
Element to assess projected water needs and sources for at least a 10-year
planning period, considering the SFWMD Regional Water Supply Plan, the
applicable District Water Management Plan, as well as applicable
consumptive use permit(s). [s.163.3177 (6)(d), F.S.]. The plan must address
the water supply sources necessary to meet and achieve the existing and
projected water use and demand for the established planning period,
considering the SFWMD Regional Water Supply Plan [s.163.3167(9), F.S.1.
7. To the extent necessary to maintain internal consistency after making
changes described in Paragraphs 1 through 5 above, revise the
Intergovernmental Coordination Element to ensure coordination of the
comprehensive plan with the SFWMD Regional Water Supply Plan
[s.163.3177(6)(h)1., F.S.].
8. While an Evaluation and Appraisal Report is not required, local governments
are encouraged to comprehensively evaluate, and as necessary, update
comprehensive plans to reflect changes in local conditions. The evaluation
could address the extent to which the local government has implemented the
need to update their Work Plan, including the development of alternative
water supplies, and determine whether the identified alternative water supply
projects, traditional water supply projects, and conservation and reuse
programs are meeting local water use demands [s.163.3181(3), F.S.].
9. A local government that does not own, operate, or maintain its own water
supply facilities, including, but not limited to, wells, treatment facilities, and
distribution infrastructure, and is served by a public water utility with a
permitted allocation of greater than 300 million gallons per day is not required
to amend its comprehensive plan in response to an updated regional water
supply plan or to maintain a work plan if any such local government's usage
of water constitutes less than 1 percent of the public water utility's total
permitted allocation. However, any such local government is required to
cooperate with, and provide relevant data to, any local government or utility
provider that provides and natural groundwater aquifer recharge element
updated in accordance with s. 163.3191. Any local government may verify its
qualifications for the exemption with the Florida Department of Economic
Opportunity (DEO) [s. 163.3177(6)(c)4., F.S.1.

10-Year Water Supply Facilities Work Plan Update
2.0 BACKGROUND INFORMATION
2.1 Overview
The City of Miami, known as the "Magic City", is located in Southeast Florida, in
Miami -Dade County on the Miami River, between the Florida Everglades and the
Atlantic Ocean. The current boundaries of the City encompass an area of
approximately 35 56 square miles (including both land and water areas). The City of
Miami was incorporated in 1896 and has grown into one of the world's renowned
centers where people can work, live and play while enjoying a high quality of life.
The City of Miami, known for its diverse culture and ethnicities, is the largest
municipality in Miami -Dade County.
The City of Miami is substantially built -out. An evaluation of land uses, excluding
water by gross acreage has revealed the following approximate breakdown:
Industrial (1.77%); Vacant (3.01%); Residential (33.57%); Government/Institutional
(4.89%); Commercial (5.87%); Mixed -Use (0.49%); Parks (5.52%); Utilities (3.91 %);
and Roads/ROW 20.56%). Between 2000 and 2010, tThe City of Miami population
grew from 362/170 to 399,'157, an increase of tcn perccnt (10.2%)4 estimate by the
U.S. Census Bureau (July 2021) was 439,890. By all From the projections, growth
will continue to occur in Miami and the region, with future development potential and
population growth limited by the scarcity of vacant and developable land. Current
estimates of population trcnds have incorporated thc rcccnt deluge of development
and rcdcvclopmcnt of new large scale residential projects. The City's greatest
development potential will occur as mid to high rise rcdcvclopmcnt projccts. For
these reasons, it is anticipatcd thc City of Miami will receive a much grcatcr sharc of
thc County's population growth.
For the purposes of this Update, the population projections data found in the Miami -
Dade County 10-year Water Supply Facilities Work Plan Update (Exhibit C-4, WASD
Retail Municipal Customers), adopted in April 2022, will be utilized (See 3.0 Table
2.2 Relevant Regional Issues
The Lower East Coast, LEC, Planning Area traditionally has relied on fresh
groundwater from the Surficial Aquifer System, SAS, and fresh surface water from
Lake Okeechobee as the primary water source for urban, agricultural, and industrial
uses. In many areas of the LEC Planning Area, development of these sources has
been maximized due to potential impacts on the regional system, wetlands, existing
water users, and the potential for saltwater intrusion. As population and water
demand increased, the development of other water source options also increased.
Therefore, new or increased allocations from these freshwater sources will be
reviewed on an application -by -application basis to determine if a project meets the
consumptive use permitting criteria. As a result, diversification of water supply

sources, such as use of the upper Floridan aquifer, increased storage, reclaimed
water, and appropriate water conservation has been occurring in the LEC Planning
Area and is expected to continue to occur in the future. The source options are
dependent on location, use type, demand, regulatory requirements, and cost.
Since the previous water supply plan updates, the national economic downturn has
growth, leading to a rcduccd ratc of incrcasc in future urban water demands.
Although population growth may be slowcr than prcviously projcctcd, the growth is

Additionally, Southeast Florida is one of the most vulnerable regions to the impacts
of climate change and sea level rise as a result of our flat topography, porous
limestone geology, and dense coastal development. Climate change and sea level
rise are expected to present significant challenges relating to water resource
planning, management and infrastructure for the counties located in south Florida,
including Broward, Miami -Dade, Monroe, and Palm Beach Counties. The primary
concern to water supply is salt water intrusion into the freshwater Biscayne aquifer,
the primary source of drinking water in Miami -Dade County. Local governments and
water utilities in the southeast Florida region have begun to formalized the
integration of water supply and climate change considerations as part of coordinated
planning efforts, including updates to local government and water utility 10-year
Water Supply Facility Work Plan and enhancements to local government's
Comprehensive Plans. Key considerations for communities within the four County
Compact planning area areas include: 1) sea level rise, 2) saltwater intrusion, 3)
extreme weather, and 4) infrastructure investments to support diversification and
sustainability of water supply sources, and adaptive storm water and wastewater
systems. Results of evaluation and data analysis completed to date indicate that
within the next thirty years MDWASD will be able to operate well fields and water
treatment facilities as designed, as groundwater modeling indicates even with a high
level of projected sea level rise, our these well fields will not be impacted by salt
water intrusion. Further modeling is currently underway to extend the planning
scenarios fifty years out and will include climate changes such as increases and
decreases in annual precipitation, and extreme weather events.
Regional issues that affect the City of Miami include minimizing pressure on the
Everglades and Biscayne Bay ecosystems and Biscayne and Floridan Aquifers. To
that end, the Comprehensive Everglades Restoration Plan (CERP) is providing the
foundation for one of the largest ecosystem restoration projects in the world. The
SFWMD and the US Army Corps of Engineers have partnered in order to restore,
protect and preserve the water resources of central and southern Florida, including
the Everglades. Various projects under CERP help ensure the proper quantity,
quality, timing, and distribution of waters to the Everglades and all of South Florida.
DRAFT August 2023
10
City of Miami
10-Year Water Supply Facilities Work Plan Update
The goal of CERP is to capture fresh water that now flows unused to the Atlantic
Ocean and the Gulf of Mexico and redirect it to areas that need it most.
The SFWMD's priorities have focused on creating Water reservation rules to
facilitate construction of CERP project components. The City is in support of CERP
and other restoration projects listed in the 2018 Lower East Coast (LEC) Water
Supply Plan Update that further the Northern/Southern Everglades 20-year
commitment to Everglades restoration, including the C-111 South Dade, C-111
Spreader, Biscayne Bay Coastal Wetland BBCW L-31 East Flow -way, BBCW
Deering Estate and BBCW Cutler Wetlands projects.
The South Florida Water Management District is the state agency responsible for
water supply in the Lower East Coast planning area which includes the jurisdictional
boundaries of the City of Miami. SFWMD plays a pivotal role in resource protection,
through criteria used for Consumptive Use Permitting. As pressure increased on the
Everglades ecosystem resource, the Governing Board initiated rule making to limit
increased allocations dependent on the Everglades system. As a result, the
Regional Water Availability Rule was adopted by the Governing Board on February
15, 2007 as part of the SFWMD's water use permit program. This reduced reliance
on the regional system for future water supply needs, mandates the development of
alternative water supplies, and increasing conservation and reuse.
Even with an ever-increasing population, withdrawals from the Aquifers will be
limited, greater conservation will be required to reduce per capita use; and reclaimed
water must continue to be an important alternative water source per the 2008 Leah
G. Schad Ocean Outfall Program. The City does not have any domestic wastewater
facilities which discharge to the ocean, but supports Miami -Dade County efforts in
reducing wastewater outflows and providing for reuse, which are noted in Section
4.5.1.2. (page 4-8) in the MDWASD 10-year Plan, adopted April 2022.
The 2018 Lower East Coast Water Supply Plan Update notes that a number of
utilities have diversified their water supplies, including treatment and storage
technologies, and water conservation programs. These alternatives include
constructing brackish Floridan aquifer wells and reverse osmosis treatment plants,
reclaimed water treatment and distribution facilities, and aquifer storage and
recovery systems.
From FY2013 to FY2018, the SFWMD provided more than $3 million in alternative
water supply funding for 11 projects in the LEC Planning Area. Funded projects
created 9.25 million gallons per day (mqd) of new reclaimed water capacity and 4.19
mgd of additional reclaimed water distribution or storage in the LEC Planning Area.
The 2018 Lower East Coast Water Supply Plan Update water supply major issues
are as follows: 1. Fresh surface water and groundwater are limited; further
withdrawals could have impacts on the regional system, wetlands, existing legal
uses, and saltwater intrusion. As a result, additional alternative water supplies need

to be developed. 2. Surface water allocations from Lake Okeechobee and the Water
Conservation Areas are limited in accordance with the Lake Okeechobee Service
Area RAA criteria. 3. Construction of additional storage systems (e.g., reservoirs,
aquifer storage and recovery systems) to capture wet season flow volumes will be
necessary to increase water availability during dry conditions and attenuate
damaging peak flow events from Lake Okeechobee. 4. Expanded use of reclaimed
water is necessary to meet future water supply demands and the Ocean Outfall Law.
5. Expanded use of brackish groundwater from the Floridan aquifer system requires
careful planning and wellfield management to prevent undesirable changes in water
quality.
Through the Natural Groundwater Aquifer Recharge Goal AR-1 the City supports the
actions MDWASD and Miami -Dade DERM in protecting the integrity and functions of
groundwater aquifer recharge areas.
As further outlined in Section 3.6 of this Plan the City will support and assist in
disseminating information to the extent possible on water conservation related
programs and incentives from Miami -Dade County and SFWMD. As a retail
customer the City will support MDWASD efforts outlined in the Miami -Dade County
Water Conservation Plan, dated November 2020.
As a result of these regional water supply issues the City has updated its "Water
Supply Facilities Work Plan" as required by Florida Statutes. Since the City is a retail
customer, the adopted policies within the City's Comprehensive Plan currently
require the City to be consistent with the approved versions of the SFWMD's
LECWSP (adopted November 8, 2018), and the County's 10-Year Water Supply
Facilities Work Plan (adopted April 2022). The City shall coordinate with the
County's Work Plan to identify and develop those water supply projects necessary to
meet the City's projected water demands.
Additional Comprehensive Plan policies require the City to consider the impacts of
climate change and sea level rise as an integral component of all planning
processes. Rise in sea level shall be taken into consideration in all future decisions
regarding the design, location, and development of infrastructure and public facilities
in the City to meet or exceed adopted Level of Service (LOS) Standards. The City
shall work with Miami -Dade County to support the implementation of climate related
policies.
The City of Miami has also established a "City of Miami Sea Level Rise Committee",
February 26, 2015, to study sea level rise and its effect on the City of Miami and
make recommendations. The Office of Resilience and Sustainability was formed in
November 2016 to enhance these efforts. In 2019, the City of Miami consolidated
the Sea Level Rise Committee and Waterfront Advisory Board into the Climate
Resilience Committee. The charge of the Committee has expanded to include: (1)
recommending, to the Commission, changes to City Code and policy that will help

the City thrive in the face of all climate change threats, and (2) providing input on
City -owned waterfront land use issues when tasked.
3.0 DATA AND ANALYSIS
The intent of the data and analysis section of the Work Plan is to describe the
information that local governments need to provide to state planning and regulatory
agencies as part of their proposed comprehensive plan amendments, particularly
those that would change the Future Land Use Map (FLUM) to increase density
and/or intensity. Additionally, population projections should be reviewed for

3.5 Water Supply Provided by Othcr Entities MDWASD
The Miami -Dade County 210-Year Water Supply Facilities Work Plan (201'1 2033
April 2022) is attached as Appendix BA. The County Work Plan generally contains
all supply and distribution information concerning its Countywide facilities,
conservation measures, alternative water supply projects, historical data and
projections, planned facilities, capital improvements, climate change and sea level
rise impacts. The intent of the County Work Plan is to meet the statutory
requirements mentioned in subsection 1.2 of this plan and to coordinate the
MDWASD's water supply initiatives with the SFWMD's Lower East Coast Water
Supply Plan Update.
The SFWMD initially issued a Water Use Permit, (WUP) for Miami -Dade County on
November 15, 2007. The water use permit limits the annual allocation and the
maximum monthly allocation until the permit expires. The hlatest modifications to
this MDWASD WUP, No.1300017-W, to the MDWASD were approved on February
gth, 2015 March 8, 2022 and will now expire on December 27, 2065. The modificd
and cxtcndcd Pcrmit has a duration of 20 ycars and cxpircs on Fcbruary 9th, 2035.
The MDWASD's service area is all portions of Miami -Dade County within the Urban
Development Boundary (UDB), excluding the service areas of North Miami Beach,
Homestead, Florida City, and approximately 65% of North Miami's service area.
The water demands of the areas within the Urban Expansion are considered in the
10-year planning horizon between 2015 2033.
The MDWASD water service area contains interconnected systems and, for the
most part, functions as a single service area. The service area may be is broken
down into three sub areas by water treatment facilities: the Hialeah -Preston area,
the Alexander Orr Jr. area, and the South Dade area.

In the 20 Year Work Plan, thc MDWASD is committed to meet the water demands
for the municipalities and unincorporated areas within he its service area. The City
of Miami is served by both the Hialeah -Preston (north of Flagler Street) sub -area
and Alexander Orr, Jr. sub -area (south of Flagler Street) water treatment plants.
The Hialeah -Preston sub -area is comprised of dedicated low-pressure pipelines,
remote storage tanks, pumping facilities, and high pressure systems. This sub -area
delivers water to Hialeah, Miami Springs, the City of Miami, and other portions of
northeastern Miami -Dade County. The Hialeah -Preston sub -area, water treatment
plant is supplied by four water supply wellfields (Hialeah- capacity 12.5 MGD; John
E. Preston — capacity 53.28 MGD; Miami Springs — capacity 79.30 MGD; and
Northwest -149.35 MGD), with a total designed capacity of approximately 245
220.94 MGD.
Alexander Orr Jr. sub -area is comprised of a high pressure system with two major
piping loops. This sub -area delivers water to nearly all of Miami -Dade County south
of Flagler Street to SW 248th Street, including Virginia Key, Fisher Island, The

Village of Key Biscayne and, upon request, to the City of Homestead, and Florida
City. The Alexander Orr, Jr. subarea, water treatment plant is supplied by four water
supply wellfields (Alexander Orr, Jr.- capacity 74.4 MGD; Snapper Creek — capacity
40.0 MGD; Southwest — capacity 161.2 MGD; and West 32.4 MGD), with a total
designed capacity of approximately 308 MGD. In this subarea, there are also Upper
Floridan Aquifer wells at two of the wellfields (West Wellfield (WWF) and the
Southwest Wellfield (SWWF)). These wells have a total capacity of 25.08 MGD.
MDWASD anticipates using these wells for storage of fresh Biscayne Aquifer water
during the wet season (when operating water levels in the canal allows) for
extraction and use in the dry season. In order to use the Upper Floridan Aquifer
wells, the MDWASD installed an ultra -violet (UV) light disinfection system at both the
SWWF and the WWF to provide treatment of the Biscayne aquifer water prior to
injecting in the Floridan Aquifer. MDWASD is currently cycle testing the Aquifer
Storage/ Recovery (ASR) wells at both the West and Southwest Wellfields.
Hialcah-P-reston sub ar comprised of dedicated low-pressure pipelines, remote

Northwcst 1/19.35 MGD), with a total dcsigncd capacity of approximately 295 MGD.
3.6 Conservation
Water conservation is the key to maintaining the health and productivity of the
Surficial and Floridan Aquifers. Promoting water conservation equipment,
techniques, and practices will benefit customers economically and maintain a
realistic water demand picture for utilities. Protection of the aquifer system and
wellfields (Figure 3.) through conservation and reuse, recharge enhancement,
limitations on withdrawal, regulation of land use, and maintenance of minimum flows
and levels will ensure the availability of an adequate water supply for all competing
demands, maintain and enhance the functions of natural systems and preserve
water quality.
The City of Miami works in coordination with MDWASD, SFWMD and state efforts
aimed at promoting conservation through a variety of means including:
• Water Use Efficiency requirements included in the Code of Miami -Dade
County
• Limiting Irrigation Hours
• Florida -Friendly Landscape Ordinance
• Rain Sensor Ordinance
• Water Conservation Rate Structure
• Leak Detection and Repair Program
• Public education
• Offering low-cost kits to its customers to reduce water use in their homes
(High -Efficiency Fixtures).

10-Year Water Supply Facilities Work Plan Update
MDWASD has developed a Water Conservation Plan (November 2020) which is
included as Exhibit 29, MDWASD 10-Year Water Supply Facilities Work Plan (201/1
2033 April 2022). As a retail customer the City of Miami will support MDWASD
efforts outlined in the Miami -Dade County Water Conservation Plan, dated
November 2020.
For more information about WASD's Water Conservation Program visit
http://www.miamidade.gov/conservation/home.asp.
3.6.1 County -wide Issues
The Miami -Dade Water Use Efficiency Plan
Currcntly, MDWASD is implementing a 20-year Water Use Efficiency Plan and is
experiencing reductions in per capita water consumption by implementing all Best
Management Practices (BMPs) included in the 20-year Water Use Efficiency Plan,
which was approved by the South Florida Water Management District in May 2007.
The lower demand is also the result of lower -than -projected population growth,
permanent landscape irrigation restrictions, water loss reduction from Florida
Friendly landscaping in new construction, in right of ways, and the installation of high
efficiency plumbing fixtures in new construction and some reuse within the three
wastewater treatment plant sites or in their vicinities. Because of these efforts, the
County has achieved 16.19 MGD of water saving through fiscal year 2021.
As a result, the Water Conservation projections included within the MDWASD 10-
Year Water Supply Facilities Work Plan were revised based on the 2010 Annual
Water Conservation Plan Conscrvc Florida Rcport 2021 Annual Report (March 2011
January 1, 2021 — December 31, 2021), Exhibit F, MDWASD 10-Year Water Supply
Facilities Work Plan. The savings from water conservation translate into more
potable water available for residential and non-residential use, capital and operating
savings, which allow systems to defer or avoid significant expenditures for water
supply facilities and wastewater facilities.
Water Conservation Plans and Development Codes
Miami -Dade County has developed recommendations for new developments that
would achieve higher water use savings than currently required by code. Miami -
Dade County has enacted water use efficiency -legislation including permanent
landscape irrigation restrictions, landscape ordinances requiring Florida Friendly
landscaping in new construction, in right of ways, and the installation of high
efficiency plumbing fixtures in new construction and some reuse within the three
wastewater treatment plant sites or in their vicinities. This was done by The Board of
County Commissioners amending Water Use Efficiency standards creating or
amending -Sections 8-31, 32-84, 8A-381, 32-8.2, 32-83.1, 18A, 18B of the Code of
Miami -Dade. All future development within the City will be is required to comply with
these water conservation measures as provided through these water use efficiency
legislations, which may be amended from time to time. The list of legislation and
ordinances relating to water use efficiency standards are presented in Appendix D of
DRAFT August 2023

10-Year Water Supply Facilities Work Plan Update
the MDWASD Water Supply Facilities Work Plan and are also posted in the Miami -
Dade Water Conservation Portal.
Per Capita Consumption
The MDWASD establishes per capita consumption for all municipalities including
those in its retail customer service area. Based on this data, the MDWASD will work
with the municipalities to address those with higher than average per capita usage
and will target programs for those areas. The County anticipates that the
implementation of the BMPs identified in the 20-Year Water Use Efficiency Plan will
result in an adjusted system wide per capita of 133.56 139 gpcd by 2033 through the
planning 10-year planning period.
The City has been successful in implementing, as applicable, its water conservation
policies and supporting efforts by Miami -Dade County and the South Florida Water
Management District in their efforts to promote water conservation and reuse. The
City promotes the policies, requirements and procedures as outlined in Section 3.7
this 10-Year Water Supply Facilities *Work Plan Update. As shown by the City's per
capita consumption rate of 97.54 gallons per capita vs. 139 generally systemwide,
the City has been a leader by this metric.
3.6.2 Local Government Specific Actions, Programs, Regulations, or Opportunities
The City will coordinate future water conservation efforts with the MDWASD and the
SFWMD to ensure that proper techniques are applied. In addition, the City will
continue to support and expand existing goals, objectives and policies in the
comprehensive plan that promote& water conservation in a cost-effective and
environmentally sensitive manner. The City will continue to actively support the
SFWMD and Miami -Dade County in the implementation of new regulations or
programs that are designed to conserve water during the dry season.
3.7 Reuse
3.7.1 Regional and County -wide Issues
State law supports reuse efforts. For thc past ycars, Florida's utilities, local
governments, and water management districts have led the nation in implementing
water reuse programs that increase the quantity of reclaimed water used and public
acceptance of reuse programs. Section 373.250(1) F.S. provides that "water reuse
programs designed and operated in compliance with Florida's rules governing reuse
are deemed protective of public health and environmental quality." In addition,
Section 403.064(1), F.S., provides that "reuse is a critical component of meeting the
state's existing and future water supply needs while sustaining natural systems."
The City of Miami supports watcr rcusc initiativcs undcr considcration by both the

WASD is currently implementing a total of 16.49 MGD of reuse at each of the
Wastewater Treatment Plants, primarily for in -plant (process water) use. In addition,
WASD will be providing up to 15 MGD of reclaimed water from the South District
Wastewater Treatment Plant to the FPL facilities at Turkey Point, per Miami -Dade
County Resolution No. R-579-20 approved by the BCC on June 16, 2020.
3.7.2 Local Government Specific Actions, Programs, Regulations, or Opportunities
The City will continue to support the SFWMD and Miami -Dade County water reuse
projects, and implementation of new regulations or programs designed to increase
the volume of reclaimed water used and public acceptance of reclaimed water.
4.0 INTERGOVERNMENTAL COORDINATION
The provision of water supply needs in the City of Miami is achieved in coordination
with local, county, and regional partners including Miami -Dade County WASD and
South Florida Water Management District. MDWASD is the City's primary water
partner as they provide the City its water service utilities. As part of the water supply
planning process and intergovernmental coordination in general the City has
reviewed the Miami -Dade County Plan while outside agencies will review the City's
Plan. MDWASD ensures that water supply services are provided to most potable
water users of Miami -Dade County in the most efficient and effective manner.
SFWMD acts to protect the region's water supply resources and coordinates the
implementation of state water regulations and policies through local water planning
efforts and water supply services.
In this update of the Water Supply Facilities Work Plan, the City has reviewed its
water supply related Objectives and policies and updated them as necessary.
Changes to the Objectives and policies are outlined in Section 7.0. Policies are
included which detail coordination efforts with both MDWASD and SFWMD. As a
retail customer, the City must coordinate through data collection and billings the
adequate supply of water and conservation practices with MDWASD and implement
the requirements of County Code.

56.0 CLIMATE CHANGE AND SEA LEVEL RISE
Southeast Florida is one of the most vulnerable regions to the impacts of climate
change and sea level rise as a result of our flat topography, porous limestone
geology, and dense coastal development. Climate change and sea level rise are
expected to present significant challenges relating to water resource planning,
management and infrastructure for the counties located in south Florida, including
Broward, Miami -Dade, Monroe, and Palm Beach Counties. These communities have
agreed to partner in regionally -coordinated climate mitigation and adaptation
strategies as part of the Southeast Florida Regional Climate Change Compact
(Compact) and have adopted a Regional Climate Action Plan (RCAP) which
highlights "Water Supply, Management, and Infrastructure" as a primary focal area.
http://southeastfloridaclimatecompact.org
Investigations and evaluations conducted at the national, regional, and local levels
have reinforced the need to plan for the predicted impacts of more frequent and
severe drought, increases in tidal and storm -related flooding, and the loss of coastal
wellfield capacity due to saltwater contamination. In the absence of proactive
planning, these impacts will present liabilities for coastal and inland communities
DRAFT August 2023

City of Miami
10-Year Water Supply Facilities Work Plan Update
with implications for urban water supplies, water and wastewater infrastructure, and
both regional and local drainage/flood control systems. Investments in water supply
planning and infrastructure that account for these predicted trends will improve the
resilience of our communities, provide public health benefits, and reduce the
potential for economic losses.
The City of Miami along with Miami -Dade County, Broward, Monroe, Palm Beach
Counties, local governments and water utilities in the southeast Florida region have
begun to formalized the integration of water supply and climate change
considerations as part of coordinated planning efforts, including updates to local
government and water utility 10 year Water Supply Facility Work Plan and
enhancements to local government's Comprehensive Plans. Key considerations for
communities within the four County Compact planning area include: 1) sea level rise,
2) saltwater intrusion, 3) extreme weather, and 4) infrastructure investments to
support diversification and sustainability of water supply sources, and adaptive storm
water and wastewater systems.
Below are synopses of these considerations as enumerated more fully in the
MDWASD 10-Year Water Supply Facilities Work Plan (April, 2022), Section 6
Climate Change and Sea Level Rise Plan.

Sea level rise produces varied challenges with the respect to water resources
sustainability, water management, and water/wastewater facilities and infrastructure.
Impacts include saltwater contamination of coastal wellfields, infiltration of
groundwater with chloride levels into wastewater collection systems, impairing
normal operations and maintenance as well as opportunities for beneficial use of
reclaimed water as an alternative water supply. Water management systems are
also at risk with systems constrained by rising groundwater and tail water elevations
which reduce soil storage and discharge capacity, with increased potential for both
inland and coastal flooding and less opportunity for long-term storage of storm water
for beneficial reuse.
These realities necessitate consideration of plans and investments that may be
needed to compensate for loss of existing water supplies through relocation of
wellfields and the development of alternative water supplies while also seeking
opportunities to expand regional water storage opportunities. These investments and
considerations are in addition to concurrency planning for population growth and
water demands that are typical requirements for water supply planning
requirements.
For all planning purposes Miami -Dade County (including the City of Miami) relies
upon the Unified Sea Level Rise Projection for Southeast Florida developed by the
South Florida Regional Climate Change Compact (Figure 6-1). The projection
was updated in 2019 by a panel of scientists to reflect the best available data. The
latest science indicates that mean sea levels could be between 10 to 17 inches
higher than 2000 levels by 2030. By 2070, average levels are expected to be 21
to 40 inches higher.
The City of Miami established a "City of Miami Sea Level Rise Committee", February
26, 2015, (Resolution File Id: 15-00059) to study sea level rise and its effect on the
City of Miami and make recommendations. As stated previously, the Office of
Resilience and Sustainability was formed in November 2016 and In 2019, the City of
Miami consolidated the Sea Level Rise Committee and Waterfront Advisory Board
into the Climate Resilience Committee.
Greater Miami & the Beaches (GM&B) is a collaboration among Miami -Dade County
and the cities of Miami and Miami Beach, created to respond to the global
trends major cities face including urbanization, globalization and climate change.
GM&B was selected to join the 100 Resilient Cities Program pioneered by the
Rockefeller Foundation in 2016. In 2019, GM&B released the Resilient305 Strategy
that addresses prioritized resilience challenges, which was developed through
extensive intergovernmental and community collaboration
(https://resilient305.com,). The resilience strategy is designed to address GM&B's
key shocks and stresses, such as hurricanes and infrastructure failure. The
strategy includes actions related to water management including water quality,
flooding mitigation, and infrastructure hardening.

As a 100 Resilient Cities partner MDC was eligible and selected as one of five
global communities to pilot the City Water Resilience Approach to diagnose the
strengths and weaknesses of the water system using quantitative and qualitative
indicators and to develop an action plan that builds water resilience. WASD led
this process that bridged water, wastewater, and stormwater management, both
upstream and downstream of our county, and which directly advances water -
related actions in the Resilient305 Strategy, particularly Action 54: Employ a One
Water Approach. Some key messages we heard from our stakeholders include
the importance of better coordination between water stakeholders, the need for
catchment -level partnerships and water management projects and practices, and
a strong call for sharing water quality and related data to ensure evidence -based
decision -making, and the need for proper valuing of ecosystem services.

6 6.2 Saltwater Intrusion
The primary concern to MDWASD water supply is salt water intrusion into the
freshwater Biscayne aquifer, the primary source of drinking water in Miami -Dade
County. Results of evaluation and data analysis completed to date indicate that
within the next thirty years MDWASD will be able to operate its wellfields and water
treatment facilities as designed, as groundwater modeling indicates even with a high
level of projected sea level rise the county's wellfields will not be impacted by salt
water intrusion.
However, with that being said, aAlong the coast of southeast Florida, and several
miles inland, groundwater supplies and potable wells are vulnerable to saltwater
contamination. The Biscayne Aquifer which serves as the region's primary water
supply is a shallow, surficial aquifer characterized by limestone karst geology which
is highly porous, and transmissive. As a result, coastal saltwater intrusion of the
aquifer has begun to restrict coastal water supplies and necessitates the
development of western wellfields, changes in wellfield in water management
operations, and reclaimed water projects to enhance aquifer recharge. Historically,

Saltwater intrusion in Miami -Dade County is monitored through a joint effort of the
Miami -Dade WASD, Miami -Dade Department of Regulatory and Economic
Resources (RER), and the U.S. Geological Survey (USGS) through Joint Funding
Agreements and as part of the WUP #13-00017-W requirements.
5 6.3 Extreme Weather Events
As extreme events increase in frequency and severity, the City and MDWASD will
consider impacts and risks associated with drought, water shortages and reduced
groundwater tables, all of which can hasten saltwater intrusion and exacerbate water
supply impacts. Conversely, more intense and rapid rainfall will cause flooding,
increased runoff, as well as impacts to the natural systems and provide less
recharge potential.
Extreme rainfall events can increase damage to low-lying utility infrastructure and
prolong surface water flooding. The increases in groundwater and sea level will
challenge the function of drainage systems and can contribute to excessive flooding
for even mild storm events. Predicting for the combined influences of storm events,
high tides and sea level rise on drainage system functions and other public
infrastructure is a critical planning need as is the assessment of viable water
supplies and impacts to the natural systems from prolong droughts.
WASD entered into a JFA in 2014 (JFA 14GGESMC0000110) with the USGS
to continue the modeling effort, and will develop additional future scenarios with
County Departments, local governments, a n d regional agencies for further
climate change and sea level rise assessment.
a 6.4 Infrastructure Development
With increasing climate change there is a need to diversify water supply sources,
treatment technologies and to provide adaptive storm water and wastewater
infrastructure design criteria to ensure long-term sustainability of key facilities.
a and and carbon footpri � at r accerba the rite -cam e impacts
Strategic infrastructure planning should incorporate these constraints and work
within with the Goals, Policies and Objectives of the City's Comprehensive Planning
MCNP processes and water supply facility work plans- to provide for long-term
sustainable and balanced approach for future development. Additionally, WASD
requires that capital improvement projects include an assessment of climate chance
and sea level rise, as stated in Section 6.2 of the Work Plan adopted in April 2022
and included in Section 2-1, Code of Miami -Dade County.

10-Year Water Supply Facilities Work Plan Update
Options that provide for a diversification of water projects and protection of
resources will be fundamental to this effort and may include: regional water storage
such as the C-51 Reservoir; aquifer storage and recovery (ASR); the development
and use of highly treated wastewater (reverse osmosis) for recharge hydrodynamic
barriers; the relocation and/or regionalization of wellfields and treatment facilities
away from low-lying areas; and enhancing operational flexibility.
Finally, the support of regional water conservation efforts is a proven strategy for
extending the timeline to develop these expensive alternative water supply
technologies and should be a prominent objective and dedicated effort to support
water resource protections under the threat of sea level rise and climate change.
