^EnviroAtlas w Community Summary Fact Sheet \ people 4 health 4 nature 4 economy / www.epa.gov/enviroatlas Des Moines, IA and surrounding area Towns and cities rely on clean air, clean water, green space, and other natural amenities for economic sustainability and quality of life, yet their benefits are not always fully understood or considered in local decisions. EPA and its partners are producing EnviroAtlas to help communities better use environmental assets for public good. EnviroAtlas includes an online interactive mapping application that anyone can use. The interactive map contains over 200 maps available for the U.S., as well as 100+ fine-scale maps for selected U.S. communities about existing and potential benefits from the local natural environment. The EnviroAtlas community component is based on 1-meter resolution land cover data. Information derived from these data is summarized by census block groups; more spatially explicit map layers are also provided. This fact sheet highlights some of the many community data layers available for the featured area of Des Moines, Iowa. Background The Des Moines, Iowa area was chosen as an EnviroAtlas community because it offers several opportunities to leverage existing community engagement activities. The EnviroAtlas boundary for the Des Monies area was determined using the 2010 Census definition of an Urban Area. It includes the city and suburbs of Des Moines. The area measures 880 square kilometers, and encompasses 312 census block groups. The Des Moines area is in the Western Corn Belt Plains Percent Land Cover in Community Area Water Impervious Soil/Barren Trees/Forest Grass/Herbaceous Agriculture Woody Wetlands Anken> i ii Des Mow'Ss Sources Ean OeLorme, NAVTEQ, Tomtom Intermap. in a smart P Corp, GsBCO USGS, FAO NPS NRCAN, GeoSase.

The region was historically vegetated with tall grass prairies; however, most of the region has been converted into agriculture. The community's economy is anchored in the financial and insurance industries. The largest employers include Wells Fargo & Co., Mercy Medical Center, Unity Point Health, and Principal Financial Group. The demographics of the Pittsburgh community area indicate that the potential exists for income and other disparities in the distribution of environmental assets. EnviroAtlas includes demographic maps that can help screen for potential health and well-being disparities resulting from disproportionate distribution of "green infrastructure."

There are 1,444 square meters of green space per person. In the Des Moines community area: • 14 out of 312 K-12 Schools have less than 25 percent green space within 100 meters. • There are 1,502,221 tons of carbon stored in the local tree biomass, with an additional 46,883 tons sequestered annually. • 636,939 kilograms of ozone are removed from the air by local tree biomass every year. Access to Parks Parks provide access to green space, encourage physical activity, and improve the livability and aesthetics of urban areas. Those who live closer to parks may be more likely to receive the multiple benefits associated with this proximity. • An estimated 18 percent of the Des Moines area is located within easy walking distance (500 meters) of a park entrance (dark and medium green areas in figure above). • An estimated 33 percent of the Des Moines population does not have a park entrance within half of a kilometer (yellow to red areas in figure above).
