PAG Green Infrastructure Prioritization Tool Data Descriptions and Sources
The layers on PAG’s interactive, online map
come from a variety of sources. Several were
acquired through PAG’s regional remote
sensing project and analyses in house. Others
were used with permission by their creators.
Use the map and your desired criteria to
determine priorities and opportunities to meet
your green infrastructure project goals. Select
multiple data layers to explore the relationships
between environmental conditions and social
demographics.
The map is available at

Regional Tree Canopy
PAG's analysis of 2007 NAIP imagery and 2008
PAG LiDAR, representing trees over 6 feet above
the ground, with a 1 meter resolution.
Percent Tree Canopy Cover by Census Block
PAG's analysis of tree canopy coverage
summarized to the 2010 census block geography.
Regional Surface Temperature
Eve Halper's analysis of 2008 LANDSAT thermal
data. Accurate for relative temperature comparisons
only.
Eve B. Halper, Christopher A. Scott, Stephen R.
Yool (2012), 'Correlating Vegetation, Water Use,
and Surface Temperature in a Semiarid City: A
Multiscale Analysis of the Impacts of Irrigation by
Single-Family Residences' Geographical Analysis
(2012) 44, 235–257.
Extreme Heat Event Vulnerable Population
Arizona Department of Health Services analysis of
the following U.S. Census data:
1. The number of children under the age of five;
2. The number of elderly people age 65 and
older;
3. The number of elderly people age 65 and
older who live alone;
4. The number of families whose income was
below the poverty line during the last 12
months; and
5. The number of people whose income was
below the poverty line during the last 12
months
The analysis is available here.
10,000 Tree Campaign Priorities
City of Tucson Office of Integrated Planning’s
Designated Priority Blocks for the Mayor’s 10,000
Trees Campaign: Census blocks with above
average heat exposure and below average tree
canopy in census blocks containing businesses or
residences.
Regional Pedestrian Demand Areas
From the PAG Regional Pedestrian Plan. Displays
concentrations of:
1. Pedestrian activity areas: stores, schools,
libraries, bus stops, and population density;
and
2. Populations needing access to pedestrian
facilities: children, seniors and households
without automobiles
For more information about the Regional Pedestrian
Plan, visit PAG's Bicycle and Pedestrian Program.
Tucson Bikeways
Map data maintained by PAG, Pima County and City
of Tucson. Includes shared use paths, bike
boulevards, separated bike lanes, enhanced bike
routes, bike routes, bike lanes, roads without bike
facilities, the Sun Link streetcar line and points of
interest. The map and app information are available
at PAGregion.com/Bikeways.
USDA 2013 Food Deserts
2010 U.S. Census tracts selected for limited access
to healthy and affordable food retailers, limited
income and vehicle accessibility.
The report is available here.
Shallow Groundwater Areas
From PAG’s analysis of shallow groundwater areas
in Eastern Pima County, as shown in the 2012
Shallow Groundwater Areas Report.
Shallow groundwater areas have water tables that
lie less than 50 feet below ground surface, and they
are often demarcated by indicator vegetation, such
as mesquite and cottonwood trees. These areas
benefit from nearby green infrastructure because it
helps to reduce landscape irrigation and erosion,
and increases soil moisture by slowing, spreading
and sinking stormflows.
Watersheds
U.S. Geological Survey Hydrologic Unit Code (HUC)
12 Watersheds. Available here.
Stormwater harvesting in upper parts of a watershed
is effective at reducing flood peaks downstream.
Stormwater
Pima County Regional Flood Control District
analysis of 2008 LiDAR.
These lines help you see how water flows through
your neighborhood, along the street and to the
nearest wash. Zoom in to see where water on your
property goes and to see which side of the street to
harvest or if a mid-street traffic circle may be more
appropriate.
These lines generally show how water moves
across a 2008 bare earth surface of Eastern Pima
County. Buildings, walls and underground
stormwater infrastructure (catch basins, culverts and
pipes) are not represented in the surface on which
these lines are modeled and do not influence the
location of these modeled flow lines. Minimum
accumulation area is a quarter acre.
Waste- and Reclaimed Water
Pima County GIS Library. Available here.
Check the availability of reclaimed water lines in or
near the project area.
