Task 1A - Prepare GPS Network / AutoCad Drawing of City's Stormwater System
The services required for the mapping portion of this project provided by Craven Thompson
& Associates, Inc. (CTA) shall include data collection, including topographical information of
City owned and maintained storm water structures and pipelines including, but not limited
to, manholes, junction boxes, culverts, headwalls, pipe ends, end walls, drop inlets, etc.
The services required for the inspection portion of this project will be provided by CTA
personnel experienced in storm water system inspection and analysis that include, but are
not limited to the following:
® Inspection of manhole and junction boxes
■ Inlet and catch basin inspection, and
r Pipeline video inspection with written reports (If requested, services not included)
GPS FIELD COLLECTION AND GIS IMPORTATION AND MANIPULATION
The Craven Thompson Survey crews will utilize GPS equipment to locate and input data on
storm water structures in the City if the structures and attributes do not already exist in a
CAD or GIS format. Features to be collected include aboveground structures only including
inlets, catch basins, manholes, control structures, outfalls, and headwalls. Storm structure
attributes including inverts, pipe sizes, and material will be gathered from design and as -
built plans provided by the City.
As part of this project, CTA will create a GPS Control Network for the City that can be utilized
by any surveyor or contractor in the future for both horizontal and vertical control. We
utilize the GPS Network to collect aerial LiDAR of the City to capture 3D elevations for
drainage and storm water assessment purposes. All data collected will be provided to the
City as part of this project.
CTA Engineers shall assess each accessible storm water structure and input data
into the system. Engineering Crews performing these tasks shall notify the City's project
representative if they discover a structure that may negatively affect the safety, health or
welfare of the residents of Aventura.
All attribute information will be based on already existing as-builts or other information
provided by the City. CTA will input the attributes into the geodatabase and will create
CRPNEN 1HOIMPSON & ASSOCWES INC.

VIDEO ANALYSIS (additional service if requested - not included in this proposal)
Pipe Video Inspection (Note: price for video inspection is not included in this proposal)
The City may request to provide video analysis of certain portions of the system in order to
further determine actual conditions. If desired, we shall provide the City with a video DVD
for these areas and report using video equipment with laser profile technology and
associated software that provides:
■ Actual recorded length and width measurements of all cracks within the pipe.
■ Actual recorded separation measurement of all pipe joints.
■ Pipe ovality report.
■ Deflection measurements and graphical diameter analysis report in terms of x
and y axis.
■ Flat analysis report.
■ Representative diameter of pipe.
■ Pipe deformation measurements, leaks, debris, or other damage or defects.
■ Deviation in pipe line and grade, joint gaps, and joint misalignment.
■ A video record of the actual speed at which the camera is traveling through the
pipe.
The City may waive this requirement for side drains and cross drains which are short
enough to inspect from each end of the pipe.
Video Report
Provide a high quality DVD format video with a minimum standard resolution of 720 x 480.
We would use a camera with lighting suitable to allow a clear picture of the entire
periphery of the pipe.
STORMWATER INFRASTRUCTURE SYSTEM AND INSPECTION
Using attribute data, positional data, photographic data, and video data (if applicable)
gathered during the field inventory phase, CTA will develop an assessment of the City of
Aventura storm water system. Standard maintenance items such as sediment
accumulation, surficial (temperature) cracking, and minor spalling, to more progressively
detrimental issues such as root intrusion, exposed rebar, and joint separation, then
ultimately to major structural failure modes such as complete collapse, major cracking,
major joint separation, or complete corrosion will be assessed. Prioritization of maintenance
and repair will be based on life safety, immanency of failure of system, potential obstruction
to emergency vehicles and normal traffic, business interruption, and various other concerns.
Based on the level of severity we will recommend anything from normal maintenance,
through structural repair, to complete replacement. An associated conceptual cost will be
CRPNEN 1HOI4PSON & ASSOCIKES INC
31 Page
provided for the suggested maintenance or improvements.
This type of program can be added as a maintenance layer to the G.I.S. database. Layers
based on "Maintenance Year" can be identified. For example, the database can be queried
for "Year 1 Maintenance Plan", or "Year 2 Maintenance Plan", and so on. This will allow the
City to visually identify locations requiring maintenance each year. Ultimately, a report will
be prepared and hard copies and a CD with an electronic version of the report will be
delivered to the City.
TASK 1B - GIS DATABASE PREPARATION
The GIS database preparation for this project will be provided by Craven Thompson &
Associates, Inc. (CTA) and shall include data collection, including topographical information
of City owned and maintained storm water structures and pipelines including, but not limited
to manholes, junction boxes, culverts, headwalls, pipe ends, end walls, drop inlets, etc.
The GIS will be prepared inside of an ESRI ArcGIS Version 10.3 or higher file geodatabase.
This process will provide the City with a storm water system that can be transferred out to
work with their existing AutoCAD system, but more importantly will be able to be linked with
and compatible to the Storm water systems of adjacent Cities, Miami -Dade County, and
SFWMD.
The importance of Storm water infrastructure, location, design, and modeling for future sea -
level rise has been on the forefront of all municipalities for the past several years and it is
very important to maintain the information in a format that is easily transferrable to and
compatible with the majority of participants. ESRI ArcGIS is the software and database
format most used by the market and the major City, County, State and Federal agencies to
maintain compatibility in all infrastructure (water, sewer, and storm).

TASK i - PREPARE MASTER DRAINAGE STUDY
Topography, Base Maps and Creation of a Digital Terrain Model
CTA will sub -contract aerial photogrammetry services which will include updated LIDAR data
and high resolution aerial photography. This service will be used to develop the base
information for the digital terrain model (DTM) for the drainage analysis and computer
modeling for the Master Plan. The high resolution aerial photography is approximately four
times better resolution than that available from Miami -Dade County. This LIDAR data will be
used for Task 1 through 3 of this Proposal.
The CTA Survey Department will be required to provide horizontal and vertical control for the
aerial services, as well as "ground truth" the LIDAR information. In addition, the CTA
surveyors will shoot elevations (at the front door) of all FEMA Repetitive and Severe
Repetitive Loss properties throughout the City. The vertical datum will be North American
Vertical Datum (NAVD) 1988 and tied to Miami -Dade County Land Survey Section
Benchmarks.
Minimum Technical Requirements for the surveying will be per the Florida Board of
Professional Surveyors and Mappers in Chapter 61G17-6 of the Florida Administrative
Code, pursuant to Section 472.027 Florida Statutes.
Drainage Analysis & Modeling (& Geotechnical)
Based on the DTM model, CTA will create an ICPR Software model of the existing storm
water system. We will integrate any previous models performed for the area. CTA will
provide geotechnical testing, percolation tests and soil borings, through our sub -
consultant.
At a minimum, the goal is to provide flood control for the 5 -year, 24-hour storm event where
possible. Some areas within the City were constructed at elevations so low, that there is no
practical economic solution to meet this standard; however, this will remain the level of
service target for this report. The objective will be to maintain static heads at or below the
lowest road crown elevation in each drainage basin and to minimize or eliminate standing
water on the roadways during those storm events. The next level of service goal is to
prevent standing water from exceeding the top of the road crown elevation during a 10 -year,
24-hour storm event. The third and highest level of service goal is to prevent house flooding
during the 100 -year, 72 -hour storm event.
The following design criteria will be analyzed and incorporated into the storm water
management investigation:
■ Soils Criteria
A subsurface soils investigation by our geotechnical sub -consultant, including soil borings
and percolation tests, will be undertaken to determine the soil characteristics within the City
limits. The findings of this investigation will be incorporated into the preliminary storm water

management system analysis.
Hydrology
The hydrologic simulations will be completed utilizing the Inter -Connected Pond Routing
(ICPR) computer modeling software Version 3.11 (Streamline Technology). Rainfall will be
based on an average of the South Florida Water Management District isohyetal maps for
specified design storm events. Watershed hydrographs will be prepared based upon the
South Florida Water Management District's rainfall distribution curves.
As noted earlier storm water modeling will be performed, considering the following design
storm recurrence intervals:
Design Storm
1. 5 -year, 24-hour event
2. 10 -year, 24-hour event
3. 100 -year, 72 -hour event
® Hydraulics
Level of Service
Pavement Encroachment
Street Road Crown Flooding
Finish Floor House Flooding
Watershed hydraulic simulations will be performed utilizing the ICPR computer software
system. Modeling of the project area will be based upon accepted hydraulic principles to
determine conveyance capacities of pipes; and where no pipes existed, the use of weirs to
connect adjacent basins.
SFWMD Controls
Storm water management controls, as promulgated under Chapter 40E of the Florida
Administrative Code, will be utilized in the preparation of the storm water management
plan.
CTA will determine water quality requirements and retention/detention area
opportunities, and evaluate drainage alternatives and compare their effectiveness to meet
the storm water requirements of the Master Plan.

TASK 3 -CITY-WIDE ENVIRONMENTAL/ NPDES ASSESSMENT -SUSTAINABILITY
The City's National Pollutant Discharge Elimination System (NPDES) permit for the Municipal
Separate Storm Sewer System (MS4) requires a plan of action for implementation of
stormwater management and monitoring programs that address effluent limitations related
to discharges to Biscayne Bay.
The City of Aventura partially funds an environmental assessment of Waters of the State and
Waters of the US within the City's corporate limits through the City's Interlocal Agreement
with Miami -Dade County and the other MS4 co -permittees. The County is currently sampling
water quality at selected locations within the County and providing assessment reports to
each co -permittee. The sampling data was included with the 2013-2014 NPDES Annual
Report (Permit Cycle 3). We recommend continued funding of the County's sampling and
monitoring plan since it is the most cost effective method of assessing the water quality of
surface waters within the City's jurisdiction.
Craven Thompson & Associates, Inc. (CTA) will compile the data previously collected under
Work Authorization 01-0103-134 and incorporate it into a comprehensive Operations and
Maintenance Manual for the City's stormwater system. The Manual will also incorporate the
City's "Catch Basin, Outfall Swale Inspection and Maintenance Checklist" the Public Works
Department Monthly Report forms and CTA will provide recommendations for additional
checklist items that should be added to the reports. This manual is intended to set level of
service standards for operation and maintenance of all City stormwater management and
conveyance systems in order to ensure their proper operation and to meet a desired City of
Aventura minimum level of service and the requirements of the City's NPDES MS4 permit.
Operation and maintenance shall be done so as to assure treatment of storm water or
reduction in pollutants in storm water discharges consistent with appropriate federal, state,
water management district, and local rules and permit requirements. The City's drainage
systems are near areas that are fish and wildlife habitat. This manual helps to insure that
storm water facility maintenance is done in a manner that meets the desired Flood Level of
Service while adhering to regulations protecting water quality, and fish and wildlife. This
proposed maintenance plan will be proactive to prevent or minimize flooding before it
happens and is based on thorough inspections and scheduled maintenance of the City's
storm water system.
SUSTAINABILITY OBJECTIVES
Sustainable Drainage Systems (SUDS) manage rainfall in holistic ways to reduce flows and
volumes of runoff from hard surfaces and to control and treat pollution with benefits for the
community and opportunities for wildlife. This approach to drainage gives rise to SUDS
philosophy, where quantity, quality, amenity and biodiversity benefits are treated with equal
importance.
The delivery of SUDS fits perfectly with the City's "Go Green" initiatives in terms of water
management and flood prevention. SUDS create a drainage network that will rely on mainly
natural approaches to provide stormwater conveyance and quality. The aboveground
drainage networks, if correctly designed and delivered, provide effective green corridors
CRKNEN 1HOIMPSON & ASSOCWES INC.
71 Page
where biodiversity can thrive, due to controlled flows of clean water. Thus the synergies
between delivering SuDS and providing a green initiative network can be readily
appreciated. Some treatments include: bio-swales, stormceptors, retention and detention
ponds, erosion resistant plantings and more.
We all benefit from a multitude of resources and processes that are supplied by natural
ecosystems. Collectively, these benefits are known as Ecosystem Services. Water plays an
integral part in the provision of these services. Some examples include the provision of:
® Flood protection and resilience
■ NPDES compliance
■ Supply of clean drinking water and water supply for food production
® Place creation, used for recreation and ecotourism
® Climate adaptation
Water Sensitive Urban Design (WSUD) is a concept which strives to ensure all aspects of
design, construction and use of urbanised landscapes are more sensitive to the natural
water cycle. WSUD caters for all aspects of the water cycle, including; water conservation,
reuse, drainage of surface runoff, and treatment and recycling of foul drainage.
Some specific WSUD objectives are as follows:
® Minimize impacts on existing natural features and ecological processes
■ Minimize impacts on natural hydrologic behaviour of catchments
■ Protect water quality of surface and ground waters
■ Minimize demand on the reticulated water supply system
■ Improve the quality of and minimize polluted water discharges to the natural
environment
Incorporate collection treatment and/or reuse of runoff, including roofwater and
other stormwater
Reduce run-off and peak flows from urban development
® Re -use treated effluent and minimize wastewater generation
■ Increase social amenity in urban areas through multi-purpose greenspace,
landscaping and integrating water into the landscape to enhance visual, social,
cultural and ecological values
Add value while minimizing development costs (e.g. Drainage infrastructure costs)
® Account for the nexus between water use and wider social and resource issues
0 Harmonize water cycle practices across and within the institutions responsible for
waterway health, flood management, pollution prevention and protection of social
amenity.
CRPNEN 1HOIMPSON & ASSOCWES INC.

CTA will identify potential opportunities for Aventura to implement sustainable components
into the existing surface water management. These implementations will also provide
benefits to the NPDES requirements by reducing harmful impacts from entering the surface
water management system, thus preventing potential harmful discharges to the Bay.
Sustainable implementation could also be incorporated into the City Development Codes to
have private development follow the City lead in implementing sustainable storm water
solutions.
CTA will provide a Report identifying potential sustainability implementations that the City
could include in the Capital Improvement Budget.

TASK 4 - PERFORM SEA LEVEL RISE STUDY AND ANALYSIS
This scope of services is to provide the City of Aventura with a baseline Climate Change and
Sea Level Rise evaluation for the entire City. Our subconsultant, Collective Water
Resources, LLC (Collective Water), will remain focused on the data aspects of the project
and develop a technical memorandum to document findings. Since climate change and sea
level rise are topics that typically require complex, long-term, and academic study, we will
document recommendations for the City as part of this task to increase likely effectiveness
in dealing with both climate change and sea level rise in the future. The data will be used to
predict the height of the rising sea levels and the approximate year in which they will occur.
This information will be combined with the existing citywide elevations to identify areas that
will be subjected to varying degrees of inundation. Particular attention will be given to the
need to raise existing seawall cap elevations; construct new seawalls in areas that will
require shoreline stabilization; and, install check valves on existing stormwater outfalls. The
update will include evaluations of the existing City codes governing development, including
the Land Development Code, in coastal areas. Consideration will also be given to evaluating
the existing engineering standards to recommend changes to address impacts resulting
from rising sea levels.
This is a simplified scope to provide immediate and cost-effective assistance to the City, and
it is likely that this is the first phase of a longer and more concerted effort to address both
climate change and sea level rise
Establish Climate Change Variables
Attend a project kick-off meeting with the City to review project goals, milestones, schedule,
deliverables, and budget. Consultant will prepare a technical memorandum summarizing
the various climate change variables that may influence stormwater management, including:
sea level rise, increase in rainfall intensities, rise in groundwater table/reduction in storage
capacity of the soil, increase in storm surge, and erosion. The technical memorandum will
present, for each variable, the current science, available data to support local projections,
what projections have been accepted within the southeast Florida area, and a
recommendation of which climate change variables to consider as part of the City's
Comprehensive Stormwater Management Plan. The memorandum will be delivered
electronically as a PDF document to CTA and others as directed by CTA. Consultant will
participate in one (1) meeting with Client and the City to review the memorandum and
associated recommendation. Consultant anticipates the City will select up to one (1), sea
level rise, climate change variables to establish localized projections and future conditions
scenarios. The remaining variables will be presented for the City's consideration as potential
additional variables to be evaluated in future stormwater management planning activities.
Climate Change and Sea Level Rise Plan
Based on the climate variable(s) selected above, Consultant will prepare a Climate Change
and Sea Level Rise Plan (Plan) specific to the City. Within the plan, Consultant will develop
and summarize localized projections of the selected climate change variables. Base data
CRPNEN 1HOI4PSON & ASSOCIKES INC
101 Page
for establishing localized projections may include tidal gauges, rainfall stations, digital
elevation model, and/or soil survey data depending on the climate variable(s) to be
analyzed. Utilizing the current science and locally specific data, Consultant will recommend
three (3) future conditions climate change scenarios for the City's review.
The draft Plan will be delivered electronically as a PDF document. Consultant will participate
in one (1) meeting with CTA and the City to present the draft Plan and associated
recommendations. Consultant anticipates the City will select up to two (2) future conditions
scenarios to evaluate the level of service of current and proposed stormwater infrastructure.
The Plan will be revised to reflect City comments and selected scenarios. The final Plan will
be delivered electronically as a PDF document as well as three hard copies, one for CTA and
two for the City.
Establish Model Future Conditions Input Parameters
Once the recommendations have been reviewed and scenarios selected by the City,
Consultant will develop model input parameters that may be applied by CTA within the
selected hydrologic and hydraulic model. Model input parameters will be delivered
electronically in a format mutually agreed upon by the Consultant and CTA. Consultant will
conduct one (1) conference call with CTA upon delivery of the future conditions input
parameters. Additionally, Consultant will perform a quality control review of the hydrologic
and hydraulic model prepared by CTA to confirm the future conditions input parameters are
properly applied. Consultant will deliver comments associated with the quality control
review via email.
Deliverables for this task will include:
Electronic copies of all data collected and inventory spreadsheet (delivered
electronically via FTP).
■ Meeting minutes from the SFWMD meeting (delivered electronically as a PDF)
Technical Memorandum
A technical memorandum that documents the findings of the study will be provided. This
memorandum will include recommendations for the City with an emphasis on best
management practices to reduce potential impacts.

photography, conduct limited site visits to field verify impervious areas of parcels with
ambiguous aerial images to inform subsequent measurement in GIS, make recommendations
regarding impervious area calculations.
Evaluate revenue collection methods.
Review current billing system through MD WASD with respect to procedures, billing roll
maintenance, cost, review efficacy of the execution of non-payment policy, review method for
accommodation of dormant accounts associated with rental properties, present non -ad valorem
assessment alternative collection method with relative cost, advantages and disadvantages.
Make recommendations regarding billing methods.
Prepare cost, revenue and rate analysis.
Coordinate with City and review previous two years' budgets to estimate operating and
administrative costs. Based on current Stormwater Master Plan analyses and findings, develop
five year capital improvement plan. Recommend annual renewal and replacement funding and
enterprise fund reserve levels. Based on findings, estimate annual billing units and expected
collection rate. Recommend rate(s) for the five year planning horizon.
Design of Stormwater System Rates
We will develop proposed stormwater rates based on the City's current billing method. A
detailed rate comparison will be developed to evaluate the impact of the proposed rates on
existing users and to assess the competitiveness of the City's rates with those of other
jurisdictions in the area. The City's methodology for determining stormwater equivalent
residential units will not be reviewed.
