URBAN ECOSYSTEM ANALYSIS
FOR
CITY OF MIAMI and MIAMI — DADE COUNTY
Scope of Work
Prepared by: American Forests and Sanborn
Rev. November 9, 2006
Overview
The City of Miami and Miami -Dade County are concerned that recent losses in their tree
cover due to hurricanes, citrus canker, and urban development have had a negative
impact on their green infrastructure and its ability to mitigate pollution and enhance air
and water quality. This project will develop a series of green infrastructure data layers.
that will take the form of a GIS data set and serve as the fundamental framework for: 1)
conducting ecological analyses of changes in the community's green infrastructure assets
and 2) providing decision support tools and data for the city and county to incorporate
green infrastructure into future planning. The underlying GIS dataset of the area's green
infrastructure will be developed for different time periods over the last decade and at
different resolutions to quantify damage to corresponding to landcover changes from
storms, disease, and development and their ecological and economic impacts on
stormwater management and Air and water quality. By presenting the larger framework of
green infrastructure and sharing existing data, each ofAhe issues raised by the City and
County can be addressed at the appropriate scale for the best project value.
Issue I: Land cover chance and its impact on green infrastructure -----
Question: Question: How has the County's landcover changed over the last ten years and how have
these changes affected the urban ecosystem's ability to provide ecosystem services such
as clean water, erosion control, clean air, and flood protection?
Approach: Use Landsat imagery (only available at 30m) to provide a historic landcover
change trend. We are fortunate that as part of the NOAA Coastal Services Center Coastal
Change Analysis Program (C-CAP), we are able to use two publicly available datasets
that will be completed by September 2006 for this analysis. For this project we propose
adding a third date to this sequence taken from 2006 Landsat imagery. This dataset will
be created to meet the C-CAP classification scheme and quality. These datasets will be
converted to the standard green infrastructure data sets one from 1995, a second from
2001, and a third from 2006. Using these data we can provide trend changes in
impervious surfaces, tree canopy, non -tree vegetation, bare soil and water that have
occurred over the County during the last decade. We can determine the economic value
these trend changes have had on stormwater runoff, and air and water quality. Once these
data layers have been developed, American Forests' staff will teach the City and County.
staff how to use CITYgreen for ArcGIS so that they can use the prepared data to integrate
green infrastructure into future planning.
Data source: Landsat 5 or 7 captured in 2006. C-CAP datasets, imagery and training
sites developed by NOAA CSC.
Geographic extent: For whole county including everglades (1,946 sq. miles).
Spatial resolution: 30 meter
Issue 2: Tree Loss Due to Hurricane Damage
Question: The City of Miami and Miami -Dade County has sustained tree loss due to
several hurricanes in 2004 and 2005. What is the extent of the loss and how has this
affected ecosystem services previously provided by the canopy? How can the City of
Miami and Miami -Dade County incorporate green infrastructure into future planning to
recover from the tree canopy loss and to enhance ecosystem services with future
development?
Approach: By comparing high resolution (<1 m) datasets collected in Nov 04 - Feb 05 to
those from March 2006. Storm damage can be evaluated for its impact on green
infrastructure and thus on air and water quality and stormwater runoff.
Data source:
For City of Miami: Pre -hurricane conditions will be quantified with 1 meter color
infrared imagery taken Nov. 2004 to Feb 2005. This imagery is available from the South
Florida Water Management District and was taken with ADS 40 digital camera. Post -

For Miami -Dade County: Pre -hurricane conditions will be quantified with 1 meter
color infrared imagery taken Nov. 2004 to Feb 2005. This imagery is available from the
South Florida Water Management District and was taken with ADS 40 digital camera.
Post -hurricane conditions will be quantified using the Miami -Dade County data from
March 2006 CIR imagery collect resampled to 1 m to match the pre -hurricane data
resolution.
Geographical Extent: City of Miami and the Miami -Dade County Urban Development
Boundary (UDB).
Spatial Resolution: 1 meter
PROJECT DELIVERABLES
American Forests will provide an Urban Ecosystem Analysis using CITYgreen for
ArcGIS software. This assessment calculates the values of the trees based on the air and
water quality, stormwater runoff reduction, and carbon sequestration benefits they
provide for the area of interest. The analysis uses widely accepted scientific and
engineering formulas to make these ecological value calculations. The data delivered will
be geo-referenced, and formatted to be used with the client's GIS database. Deliverables
for the approach above include:
• CD of digital, value added classified Landsat data of Miami -Dade County using
Landsat Satellite imagery from 1995, 2001, and 2006. Urban Ecosystem Analysis
summary and digital data provided on CD.
• CD of digital, value added classified data of pre and post hurricane land cover
analysis of Area(s) of Interest using recent high -resolution, multispectral imagery.
Urban Ecosystem Analysis summary and classified digital data provided for each
area selected on CD
o The data can also be subdivided by geo-political or ecological boundary,
such as council district or watershed. City and County staff may select up
to 10 total areas of interest and provide corresponding shape files for
analysis. Additional areas of interest may be analyzed for $500 per shape
file.
Forty licenses of CITYgreen for GIS software for City and County's use
• All GIS data layers will be provided in the following coordinate system: Florida
State Plane NAD_1983 _East FIPS0901; Units: feet
Deliverables (see price list)
• American Forests conducts two (1) day CITYgreen training for up to 20 people
each day at a City or County arranged facility. The training will use ArcGIS and
CITYgreen for ArcGIS software and raster data to teach students how to run
analyses on air and water quality, stormwater management, carbon storage and
sequestration.
• Project Report- an 8-12 page colorrreport summarizing the findings of the analysis
within the context of local issues. PDF on CD only (printed reports are extra). (see
examples of reports at:
http://www.americanforests.org/resources/urbanforests/analysis.php
• Written press release of the major findings of the analyses within the context of
local issues and recommendations. City/County would place the press release
with media and conduct follow up.
• Press conference/presentation: The press conference may be combined with a
presentation to local officials or community members as appropriate, or held as
separate events during our stay. Typically, a presentation is longer and provides
more detail than at a press conference. American Forests will:
o Frame stories for reporters for feature articles, typically putting local
issues and findings into the context of a national perspective. Often this
involves providing information on our other projects and multiple phone
calls with the press
o Consult with client on appropriate presenters for press conference; brief
presenters on context and pertinent issues for the press event
o Create a powerpoint presentation using data in report and additional work
conducted for analysis. This presentation is given to client for their future
use.
o Present at press conference (10-15 minute presentation) and/or at an
elected official or public presentation (30 minute) and answer questions.
o Interviews with media pre -event, day of, and post event
3
o Make images and other data or graphics to media as requested in the
formats that are requested
The city and county will organize the event, cultivate the press, invite local officials to
speak about the project, field press calls and follow up with inquiries after the event.
• Additional consulting- American Forests can work with local staff one-on-one on
using the analysis technique, tools, and data to address local planning issues or
provide additional presentations. This would be an add on to the current contract.
The City and County will provide:
• Imagery (including metadata) as described above for options selected
• Data needed in analysis such as: shape files of area(s) of interest and metadata of
project, information on local conditions such as hydrologic soils and cost of
stormwater retention facilities
• Organize and provide location for CITYgreen training.
• Place press release with identified media and conduct follow up.
• Organize press conference and cultivate media. Identify and provide local
speakers for press conference. Follow up with press post event.
• Print and distribute written report as desired:
