New Resources for EnviroAtlas Users

Using EnviroAtlas in a Health Impact Assessment (HIA)

Use cases provide examples of how EnviroAtlas data and tools can be used in different decision
contexts. Our latest use case explores the use of EnviroAtlas in an HIA evaluating a proposed
policy to promote physical fitness in public parks in the Town 'n' Country area of Tampa, Florida.

Educational Lesson Plan: "Exploring Your
Watershed"

Exploring Your Watershed is a three-part lesson module
that gets students outdoors, mapping, and simulating a
watershed. In this K-6 lesson, students will learn to:

•	Describe a watershed and how it works

•	Describe characteristics of ecosystems

•	Explain how humans can change their behavior to
protect their local watershed

New Data

Quality of Life

This is a new data topic found under the People and Built Spaces data tab in the Interactive Map.
This topic includes nine new metrics on vacancy rates and income thresholds for quality of life.
These data are available by census block group for the nation.

•	Percentage of households with incomes above twice the poverty line and below $75,000

•	Percentage of households with incomes above $75,000 and below $200,000

•	Percentage of households with incomes above $200,000.

•	Percentage of households below the quality of life threshold income

•	Threshold income for quality of life (shown below)

•	Business address vacancy rate for 2014

•	Change in business vacancy rate from 2010-2014, in percentage points

•	Residential address vacancy rate for 2014

•	Change in residential vacancy rate from 2010-2014, in percentage points


-------
Threshold income for quality of life (household), based on national value adjusted to reflect county cost of living (2008-2012).

New data also include suites of metrics related to farmland rental rates, drainage and nutrients from

agricultural fields, and land types on steep slopes. All data layers are available for the

nation. Headers below indicate the Topic under which the data can be found in the Interactive Map.
