DATE: April 23, 2019
SUBJECT: PRESENTATION OF WORK ORDER TO DEVELOP BLUE-GREEN INFRASTRUCTURE,
ROAD ELEVATION STRATEGY AND NEIGHBORHOOD PROJECT PRIORITIES
The purpose of this Letter to Commission is to present the attached work order by Jacobs Engineering.
This work order is the first step in the City's integrated stormwater management strategy. As part of the
work order, Jacobs will develop an integrated blue-green concept plan, evaluate the City's road
elevation policy, and prioritize the current neighborhood project list. These deliverables are described in
greater detail below.
• Blue-Green concept plan: the plan is an initial step toward achieving an integrated stormwater
strategy that is consistent with the 2018 recommendations by the Urban Land Institute (ULI)
Stormwater Management and Climate Adaptation Review. As part of the plan, Jacobs will
analyze various blue-green strategies and provide a list of vetted design approaches that are
applicable to Miami Beach. Additionally, Jacobs will provide illustrations of these strategies that
will be presented to residents at a community meeting.
• Road raising evaluation: Jacobs will assess the City's policy of raising the crown of roadway
elevations to 3.7' NAVD. The evaluation will provide an objective analysis and result in a
recommended approach to road elevations within the City. The recommendation may include
guidance on varying elevations depending on specific site conditions.
• Prioritized project list: this list will provide the City and its residents with a defined neighborhood
project plan. As part of the task, Jacobs will develop weighted criteria to rank neighborhood
projects. These criteria may include objective data, such as the state of water/sewer
infrastructure, or subjective analysis, such as the community's desire for the project. In addition
to the criteria, Jacobs will evaluate and revise neighborhood boundaries.
Overall these deliverables comprise a robust foundation for the City's future stormwater designs. They
not only consider neighborhood flood risks, but also highlight ideal strategies that integrate urban
planning, landscape architecture, aesthetics, engineering and sustainability elements to increase
quality of life for all residents. Additionally, the product will support the prioritization of capital
improvement projects by accounting for the condition of city sewers, fire flows in water systems, priority
inundation areas and the desire of residents to implement neighborhood improvements.
The City intends to execute this work order on Friday April 26th, 2019. If you have any questions or
commen lease contact Roy Coley, Director of Public Works.

Work Order 1 - Concept Plan for Blue-Green Stormwater
Infrastructure, Road Elevation Strategy, and Neighborhood
Project Prioritization
Work Order 1 combines the three priority tasks identified by the City of Miami Beach (CMB).
This work order will build on the work done to-date by using the existing information to achieve
near-term deliverables for developing a concept plan for blue-green infrastructure, evaluation
and recommendation of the roadway elevation strategy, as well as developing a
neighborhood/project prioritization matrix. These are critical steps that will support the ultimate
Integrated Water Management Strategy for Miami Beach.
This Work Order includes the following Tasks:
WO #1
Task 1 Blue Green Stormwater Concept Plan
Task 2 Road Elevation Strategy
Task 3 Neighborhood Project Prioritization
Task 1: Blue-Green Stormwater Concept Plan
This Task to develop a Blue-Green Storm water Infrastructure Concept Plan is being prepared
under the Jacobs contract with the City of Miami Beach (City) for a Master Design Consultant
for Integrated Water Management. Building off the recommendations in the 2018 Urban Land
Institute (ULI) Storm water Management and Climate Adaptation Review for Miami Beach, the
goal of this Task is to identify blue and green infrastructure (B-GSI) strategies to live with water
in Miami Beach.
This will involve identification of B-GSI strategies applicable to Miami Beach that integrate urban
planning, landscape architecture, aesthetics, engineering, and sustainability elements to
increase the quality of life. The plan will provide input to the development of a dynamic, long-
term, multidisciplinary, and integrated sea-level rise and stormwater mitigation strategy and will
coordinate with the City street tree master plan. This effort will be guided by stakeholder and
community input and coordinated closely with the other concurrent tasks and will ultimately
inform the Integrated Water Management Strategy.

1.1 Kickoff Meeting with Interdisciplinary City Team
CMB desires to kickstart the continued resilience approach by leveraging existing science and
focusing on immediate priorities regarding:
• Blue-green stormwater infrastructure
• Roadway elevation policy
• Neighborhood Project prioritization
This task will kick off all the above priority tasks simultaneously. Establishing clear policy,
guidelines, planning requirements and tools for these topic areas will improve near-term
decision making.
Specifically, in terms of B-GSI, the kickoff meeting will focus on goals, definitions, levels of
service, concerns, community outreach/education opportunities, and the types of renderings
desired.
1.2 Develop Preliminary B-GSI Concept Plan
This task will involve the primary information review, analyses, and production to develop the
preliminary B-GSI concept plan. This plan will be a synthesis of the above tasks to concisely
document the evaluated B-GSI strategies, the pros/cons of each strategy, where/when the
strategies can be applied, and provide a final list of strategies that are applicable to Miami
Beach.
The following activities will be undertaken within this task:
• Review of land use/cover and ownership patterns (public, residential, commercial)
• Develop relevant B-GSI planning categories (such as residential, commercial,
transportation, education, recreational and similar)
• Review of current policies, standards, and procedures related to construction projects,
with a focus on potential improvements to remove barriers and facilitate B-GSI.
• B-GSI practices evaluations: after initial screening to identify applicable options for
Miami Beach, approximately 10 viable options will be evaluated for advantages and
disadvantages of B-GSI practices/technologies, including maintenance considerations
and application to meet the topography, subsurface and dynamic tidal conditions of City
of Miami Beach that will include plan and section views of the alternatives under
consideration.
• Review of existing CIP and other planned projects, categorization of projects into B-GSI
scenarios with possible B-GSI practices
o Incorporate Neighborhood Project Prioritization results as applicable and as they
becomes available
• Living with Water concept renderings (may include bioswales, repurposing golf courses,
water detention/retention, integration with road raising). The renderings can use one
neighborhood to serve as a model for Miami Beach Living with Water or utilize a mix of
neighborhoods across the City to illustrate specific blue/green strategies (as discussed
at the kickoff meeting).

• Synthesis of the above tasks to concisely document the evaluated B-GSI strategies, the
pros/cons of each strategy, where/when the strategies can be applied, and provide a
final list of strategies that are applicable to Miami Beach.
• Identify near-term DCPs/projects that can incorporate these concepts.
Assumptions
• This activity includesonly compiling and analyzing existing data. Data are available in
electronic format; no transcription of hard copy data is assumed.
• The City will provide applicable geographic information system (GIS) data, CIP projects,
and water quality data from the ground water monitoring wells and topography based on
the most current LIDAR information.
• Concept renderings by landscape architects may include artistic hand drawings, photo
collage overlaid on existing photography to convey a proposed condition, as well as
vector diagram elements overlaid on drawings to explain function, etc. Engineered
section drawings maybe combined with these elements to show how proposed
improvements will function and look above the surface. These renderings will not
involve complex 3D modeling software or rendering engines/software and thus will not
be photorealistic or to an exact scale.
• This task does not include Hydrologic & Hydraulic (H&H) modeling.
• Sophistication level and number of renderings will be adapted to the limits of available
time and budget. Nonetheless, Jacobs represents these renderings will be sufficient to
demonstrate blue/green strategies to the public.
1.3 Present Preliminary Concept Plan at public meeting and review public input
A dynamic public meeting will be held in Commission Chambers to provide education on types
of B-GSI technologies, pros/cons, and potential applicability in the City as laid out in the
Preliminary B-GSI Concept Plan. Input from the public and how to address it will be reviewed
with the City Team.
1.4 Finalize plan and discuss with City Team
Applicable input received from the public, the City and other stakeholders will be incorporated to
produce a final B-GSI concept plan. The final plan will be reviewed with the interdisciplinary City
team and next steps will be discussed.
1.5 Present Concept plan to City Commissioners/Officials
The final concept plan will be presented to City Commissioners/Officials at a meeting and next
steps will be discussed.
Task 1 Deliverables
• Kickoff meeting & supporting materials
• Public meeting & supporting materials

• Living with Water renderings (draft and final, as appropriate)
• Preliminary and Final B-GSI Concept Plan. This plan will be a synthesis of the above
tasks to concisely document the evaluated B-GSI strategies, the pros/cons of each
strategy, where/when the strategies can be applied, and provide a final list of strategies
that are applicable to Miami Beach.
Task 2: Road Elevation Strategy
Task Order Objectives
This task validates and develops consensus around the City minimum road crown elevation
standard of 3.7 feet North American Vertical Datum of 1988 (NAVD) or other applicable
elevation and criteria, as a minimum design standard for road raising in the City of Miami Beach
(CMB).
This task order involves reviewing the current CMB policy and road design standards,
specifically the minimum road crown elevation and related design elements against the latest
flood risk information (for example, extreme tidal event observations and updated Sea Level
Rise (SLR) projections) to validate this standard.
Other design information to be reviewed may include the stormwater masterplan (including
design storms and level of service (LOS) and H&H models of the stormwater management
system). These flood risk data will serve as the current and future boundary conditions that
inform the minimum elevations and design criteria for roads and stormwater management
systems design.
The results of this analysis will be presented to the City project team for review, then to
Commissioners for consensus building around the need for and benefits of adopting these
standards for appropriate application across the City. This information will be shared along with
the Blue Green Infrastructure guidance and a broader toolbox of strategies adapted for use in
the City, to mitigate impacts from frequent flood events.
This task order is a high priority for CMB and will begin as soon as possible in parallel with the
other activities as part of this WO, to promote consistent messaging through a one-vision
approach to flood mitigation.
Activity 2.1: Define Goals and Objectives of Road Raising Program
This activity involves collecting and reviewing previous reports, studies, and data to establish a
thorough understanding of the issues, challenges, and opportunities of elevating roads in Miami
Beach and develop goals and objectives for road elevating as a key strategy for building
resilience to flooding in CMB. This goal setting workshop will be conducted as part of the Task 1
of this WO.
This Activity will include the following steps:
Step 1: Collect and review the following existing related information:
• Historical tidal observation data and updated sea-level rise projections
BI0213191348DCA
JACO BS+
• City policies, land development regulations, zoning and design guides and standards,
including Florida Department of Transportation information related to road elevation and
supporting drainage facilities
• Previous stormwater management master plan, level of service (LOS) criteria, modeling
results, and boundary conditions
• Previous public communications and engagement efforts
• Community concerns and site-specific challenges
• Previous project information, including successes, challenges, and issues for each
project
• List of planned transportation, stormwater, and road-elevating projects (capital
improvement plan [CIP])
Step 2: Attend CMB-led site visits to previous road elevation projects in the city with select task
leads to visualize challenges experienced from elevating roads and observe the implications of
with integrating other CMB projects and neighborhood needs, while providing near-term
adaptive flood mitigation. This one-day van and walking tour of key CMB projects will provide
the team with a deep understanding of the complexity of the strategy to drive a positive outcome
using said strategy.
Step 3: Align Task with presentations at the regularly scheduled monthly City Commission of
Miami Beach Sustainability and Resiliance Committee meetings.
Deliverables
• Draft technical memorandum (TM) summarizing data collection review, site visit
observations, project goals and objectives.
Assumptions
• CMB will provide requested data and van and tour guide for site visits.
• CMB will identify and invite key CMB staff to accompany team on-site visit.
• CMB will review deliverables and provide comments for submittals and requests in
timely manner.
Activity 2.2: Evaluate Existing Road Standards and Policies
This activity will evaluate the intended benefits, co-benefit opportunities, and unintended
implications of road raising in various neighborhoods with varying flood vulnerabilities based on
lessons learned from previously completed projects in Miami Beach. This task will also look at
performance-based specifications such as the use of black base,concrete wear, and other
material courses to reduce premature road surface degradation resulting from base saturation
and reduced base clearance from elevated groundwater conditions.
This evaluation will build on previously completed surface water hydrologic and hydraulic
modeling work and consider the evolving boundary conditions and increasing groundwater
levels resulting from extreme tidal events and SLR. This task does not involve updates to the
H&H models or the development of new models.This activity will involve the following steps:
B1021 3191348DCA
JACOBS
Step 1: Define goals and objectives for road elevation harmonization, including pedestrian,
cyclists, and vehicular access, visual barriers, and related stormwater improvements. The goals
and objectives of the road elevation will be coordinated with the City's modal hierarchy.
Step 2: Evaluate planning horizon and design criteria, standards, and policies, including road
classification, cross-sections, design tailwater evaluations, slopes, materials, repair and
replacement program, maintenance program, and CMB interdepartmental project review
process for road-elevation projects; these projects include streetscaping, stormwater, utilities,
and other improvements performed as part of an integrated complete street project.
Step 3: Review CMB flood vulnerabilities to varying design storms and flood mechanisms for
today and future conditions considering land use, sea walls, impervious cover, existing
stormwater management master plan, LOS criteria, asset criticality, and pumped outfalls.
Perform flood inundation mapping and geographic information system (GIS)-based spatial
analysis of varying flood scenarios to inform level of impact and appropriate LOS analysis.
Step 4: Review and validate the boundary conditions for road elevation design, considering
asset life span and future flood risk.
Deliverables
• Draft and final technical memorandum (TM) summarizing assumptions, analysis and
findings including recommendations on the road raising policy with interim application
guidance (via an application criteria matrix) for CMB's review and comment.
• Final TM with road raising policy and application guidance; and presentation to City
officials and Commission.
Assumptions
• CMB will provide requested data as needed and facilitate in-person meetings with key
CMB staff and departments regarding current policies, design standards, previous
projects, and the CIP.
• This task does not include the H&H and groundwater modeling required to validate new
assumptions, existing and future boundary conditions, and surface and groundwater
interactions.
Task 3: Neighborhood Project Prioritization
Task Objectives
This task will develop an objective evaluation system to prioritize City of Miami Beach capital
improvement projects based on critical needs of various City infrastructure systems. The project
definitions will be provided by City staff and will be evaluated to identify immediate, short and
mid-term needs to maintain the City services and idsystem LOS.
Activity 3.1: Develop Neighborhood Project Evaluation and Prioritization Process
This activity will involve developing a neighborhood project prioritization framework (matrix)
based on key metrics related to flood vulnerability and facility criticality, along with other
important criteria which may include (information from select internal stakeholders (e.g. City
BI0213191348DCA
JACO BS"
staff and officials), adjacent projects, etc.) This task will also evaluate neighborhood project
boundaries and resize as necessary.
Recognizing the extent of road and neighborhood/project flood vulnerability in Miami Beach, the
analysis will result in a ranked list of neighborhood projects and roads grouped together by
overall flood risk experienced today in relationship to existing water and sewer infrastructure.
This prioritization will also consider increased flood risk over time as conditions evolve to inform
applicable adaptation strategies and implementation timeframes to be examined for subsequent
project phases as well as consider the ongoing CIP and utilities listed below.
This work will be based on the data and information in coordination with the stormwater
modeling and the water and wastewater masterplan.
The activity will result in a decision-making process that will be communicated to CMB
leadership in preparation for a decision point (toll gate) regarding continued flood mitigation
investment in Miami Beach.
This activity will involve the following steps:
Step 1: Facilitate coordination meeting with ongoing Business Case Analysis for Flood
Mitigation project team members to review preliminary findings on the design storm scenarios
including the storm surge modelling, the ICPR4 modeling and the property value economic
analysis. This will allow the Jacobs team to build on the information obtained and analysis
performed as they relate to CMB economics and other key investment drivers.
Step 2: Develop and/or review list of projects and key roads categorized and delineated based
on geographic boundaries, land use, topography, flood vulnerability, and criticality.
Step 3: Develop evaluation criteria and weighting (prioritization matrix), and perform initial
prioritization of projects. Considerations for evaluation may include the following:
• Co-benefit opportunities and physical site constraints;
• Flood vulnerability (impact frequency and severity), including exposure to tidal and sea
level rise inundation;
• Maximum flooding depth on roadways and adjacent private property;
• Parcel and road ownership (private, city, county, and/or state);
• Land use and number of structures;
• Coordination with water and wastewater infrastructure and other asset renewal needs;
• Coordination with ongoing and planned CIP and neighborhood improvement projects
and private development and redevelopment projects, where available and applicable;
• Coordination with utility and multimodal transportation projects (FDOT/MDC);
• Stormwater management system needs.
Step 4: Review meeting with CMB project team and key department leads to review findings
and fine tune metrics.
