Comments
TRC Moderator Jim Murley began the TRC discussion and comment session with a
review of the composition and role of the TRC. He noted that the TRC:
·
Is composed of a team of 18 experts selected for their
knowledge of the issues to be addressed by the Watershed Study and Plan
·
Analyzes the work products of the consultant and comments
on the soundness of the approach, assumptions, and data to help ensure the
technical validity of the consultant's work
·
Uses its meetings to develop:
A collective list of summary comments and recommendations
on the work products that are the focus of the meeting
A list, if needed, of individual member recommendations
that reflect their specific areas of expertise
He
also noted that an outline summarizing the TRC's
overall comments and the recommendations of individual members is prepared
following each TRC meeting and submitted to the Watershed Study Project
Manager. This outline notes any differing viewpoints among members and the
reasons for such differences.
Murley then reviewed how the TRC should organize its review
comments:
I.
Important points for the SFRPC, Miami-Dade County
Department of Planning and Zoning, and Keith and Schnars
on the overall work program
II.
Key points about each of the subtasks reviewed at this
first meeting and how they relate to goals of the study
III.
Other points to consider related to the Watershed Study
and Miami-Dade County Comprehensive Plan goals for the Study
I.
Comments on the Overall Work Program
TRC members made two main comments about the
overall work program. The study needs:
·
A more holistic, integrated approach to both the study
area and the study process
·
To make the Bay more of the focal point of the study,
with everything beginning with and ending with the Bay
To accomplish these goals, TRC members made the
following comments about the steps that should be taken by the project
consultants.
·
Prepare what would amount to the foreword of the
Watershed Plan now to set the context for the study. The foreword should:
Have as the focal point the condition of
Depict the overall character and interrelationships of
the built and natural environment of the Watershed Study area
Describe the history of how the Study area got to where
it is today and the dynamics of the area
·
Correct the current disconnect between the Bay and the
landside impact by clearly showing the connection between the Bay and what
happens on the landside. This should include making sure that the water quality
of the Bay is the focus point of:
All of the analysis, including changes in land use and
the different development scenarios, as well as alternative forms and patterns
of development.
The selection of the variables for the study
A public education program as part of the study process
that would address, for example, the
impacts of changes in development practices, such as urban landscaping, have on
the water quality of the Bay and its long-term protection
·
Move the study process beyond the process of science and
maps to the process of planning for the future of the area and the creation of
a vision for the area:
Begin the study process with a holistic viewpoint
Understand what data to collect
·
Make sure the vision and plan are based in community
values and concerns i.e., what the public sees as important to their quality
of life and the character of their communities. The values should:
Address all three legs of sustainability social,
environmental, and economic
Be used when defining the study parameters and developing
the alternative development scenarios and evaluation criteria
·
Test a preliminary set of evaluation criteria with the
community early in the process as a way to build consensus around a preferred
development scenario
·
Use multiple outreach tools tailored to the area to
determine what is important to the residents. This could include:
Using radio spots, TV advertisements on local shows,
workshops, and surveys
Recognizing that different groups will have different
definitions of values; for example, to a citizen, water quality of the Bay
would be evaluated by whether it is clear and free of trash, whereas to a
scientist at Biscayne Bay, water quality would depend on very specific water
quality measurements
·
Show how the tasks and subtasks fit together and how the
information will be assimilated, including:
Integrating and synthesizing the data into a coherent
picture
Taking a more holistic approach to the project
II. Comments on Task 1, Existing Conditions
and Issues Identification
1.1 Analysis and Documentation of Relevant Studies
·
Add examples of how similar studies have been done
elsewhere
·
Contact the following organizations with plans and
studies relevant to the watershed study area:
United States Department of Agriculture Research Service
1.2 Population Growth
·
Use, in addition to population growth, the projected
number of households and jobs, which are a key variable in determining land
use, property patterns, and the future pattern and form of development
·
Look at the composition and size of future household demands,
taking into account:
The household composition and size of different cultures
The impact on household demand of internal movements
within the county, as immigrant families move from entry-level apartments to
single-family homes
·
Use household and employment projections, as well as
population projections, when projecting water demand and infrastructure needs,
including transportation
·
Consider the following factors when developing population
scenarios:
The natural resource and environmental limitations on
growth in certain areas of the watershed
The effects of tourists coming to the area
The effects of personnel of military and agencies
utilizing Homestead Air Reserve Base who may choose to remain in the area
The impacts of wet and dry years and hurricanes on
population and settlement patterns
The amount of population that could be accommodated using
not only alternative land uses, but also alternative forms of development
(e.g., rural, suburban, and urban densities with more intense infill and
redevelopment and use of transit)
·
Use the countys population figures as they are some of
the best in the state
·
Consider moving the interim planning year in the scope of
work from 2015 to 2025, which is the planning year of the county
·
Recognize that the 50-year projection is likely to
generate a large rate of errors because it is so far out in time
·
Consider Developing a map to illustrate Table 1 of Task
1.1,
1.3 Development Features
·
Make sure that the tables in this subtask clearly
distinguish between development that exists today and development that is
projected for the future.
·
Utilize, to the extent possible, the same year base line
data across jurisdictions
·
Develop a map that depicts significant places in the
study area, including strategic areas that could become significant, as well as
the unique attributes of roads, greenways, and other defining features
1.4 Natural Resources/Wildlife Resources
·
Make sure that the maps of natural resources clearly show
what environmental resources are included, and not included, in the maps
·
Develop a comprehensive map showing all the natural
resources and use this map as a framework for evaluating the alternative
scenarios, including how much land near the Bay should be protected under
different development densities
·
Develop a map that shows, if the funding were available,
the agricultural areas, greenways, including small connecting parcels in urban
areas, and open space that could be protected to create an connected system of
greenways and blueways
·
Develop more detailed information on the environmentally
significant areas in the study areas and the connection between the human and
natural environment and use this information when evaluating the impact of the
alternative development scenarios on the environment and natural resources
·
Make sure the impact of the scenarios on the environment
and natural resources is evaluated with the same level of detail as the impacts
on the human side
1.5 Water Resources
·
Use the same water modeling and water demand projections
as
·
Show the connection between the effects of surface flow
on the landside of the watershed on the water quality of the Bay, which has not
been done. (It was noted that the SFWMD is doing research that will make this
link; however, the results will not be completed prior to the end of this
study.)
·
Reexamine the use of the Storm Water Management Model
(XP-SWMM), which may be more than what is needed for this study and is designed
to model surface water runoff for an urban area and not for agricultural and
other rural areas. (It was noted that in agricultural areas, better flooding
data are needed. One resource for this type of data is the Extension Service,
which has information on the effects of flooding on different crop types.)
1.6 Description of Regulatory and Planning Agency
Jurisdictions
·
Evaluate the plans, codes, ordinances, and funding
mechanisms that will likely be needed to implement the Watershed Plan
·
Include the rules and regulations of the Biscayne Aquatic
Preserve and the
1.7 Land Inventory and Ownership Characteristics
·
Expand the definition of significant lands to include
small parcels that can be used to help create systems of connected greenway and
blueway system when analyzing ownership
characteristics
1.8 Watershed Characteristics Parameters and Thresholds
TRC
members made a number of observations about the development of the parameters
and thresholds to be used in the risk assessment of coastal development
alternatives on the functioning and dynamics of the
·
Involve community
stakeholders in the development of the ecological, economic, and
socio-political parameters used in evaluating scenario consequences
·
Prepare a
thorough and comprehensive description of how the indicator parameters were
chosen, the parts of the system they represent, where parameter values were
obtained, and some sense of the precision of those parameters
·
Note that the
parameters should, by and large, be quantitative measures of system functioning
that fulfill various ecological and economic risk assessment criteria
·
Employ a
relative weighting scheme (e.g., multi-objective utility functions or
analytical hierarchy process model) to allow a quantitative assessment of all
weighted parameters to be evaluated simultaneously
·
Establish
parameter thresholds that allow effective evaluation of the consequences of the
proposed scenarios
·
Make sure
that subsequent presentations concerning the selected parameters and
thresholds:
Include a
succinct description of the rationale behind the selection criteria for each
model parameter and variable, a sense of its spatial context, and the accuracy
and precision of the parameters
Describe how
the parameters fit together in a comprehensive assessment of their individual
and combined impacts on the water quality and sustainability of
In closing their discussion of the Task 1
subtasks, several TRC members stressed the importance of making sure that as
the process goes along, county and agency staff are comfortable with the data
and assumptions so that they are in support of the plan when it is completed
and ready for approval by the Miami-Dade County Board of County Commissioners.
III.
Comments on Other Points to Consider in Relation to Study and Plan Goals
TRC members comments in
this part of the discussion focused on Task 2, Formulate Land Use Scenarios,
and Task 3, Modeling and Impact Assessment.
Task 2: Formulate Land Use Scenarios
Members of TRC made a number of comments on the
formulation of the land use scenarios:
·
Treat Scenarios II and III as two different versions of
the same scenarios one with Urban Development Boundary movement and one
without
·
Show the consistent factors that are in all the scenarios
what they are and how they were developed
·
Develop a series of sub-scenarios to test different
variables, including the variables for the:
Selected population, household, and employment
projections
Alternative development forms and conservation programs
designed to protect the Bay
·
Make sure that Scenarios II and III include development
forms and conservation measures that will minimize negative impacts on the Bay
·
Consider in Scenarios II and III compressing development
around existing nodes through infill and redevelopment and utilization of higher
development densities, including more attached single-family units and
multifamily units and transit-oriented and mixed-use development to avoid
continuing to develop vacant land
· Incorporate in the scenarios contingencies for inter-annual variations in rainfall, including some wet years, suc
