Figure 1. Addresses increasing impervious cover and decreasing greenspace (trees, shrubs and grass) in Austin were generally located in a north-south direction between MoPac Boulevard and Interstate 35. These households were more often located in areas of high income, high home appraisal value, and low minority population. East Austin, with its combination of higher African-American and Hispanic populations, lower home appraisal values and lower household incomes had zero variances that decreased greenspace. The eight addresses along the border of this map are approximate locations.
