The site is located in both the 100-year and 500-year floodplain, indicating a high risk of flooding (source: 2016 FEMA Flood Map Service Center). 

 
 
 
 

There is high riverine flooding in census tracts X7100 (80.8) and X7002 (90.2). Additionally, the counties, Fulton (96.7) and DeKalb (93.5), also show high riverine flooding risk (source: 2021 FEMA National Risk Index). 

 
 

The area of development has a moderately high impervious surface, with 20-60% of the surface being impervious. Surrounding properties have up to 100% impervious surface, contributing to increased stormwater runoff and reduced natural absorption..  (source: 2021 USGS Multi-Resolution Land Characteristics Consortium, NLCD Impervious Surface 2021 CONUS). 

 
 
 
 

The Sanitary Sewer Overflows in the area, with HUC 12 ID 030701030101 and its adjacent area (HUC 12 ID 030701030102), both show a reported value of 0, indicating no significant sanitary sewer overflow risk (source: various, accessed 2024 EPA EnviroAtlas).

The respiratory risk (hazard index) due to cumulative air toxics is moderately high, with x7100 at 0.68 and x7002 at 0.70, both slightly higher than the adjacent census tract x3802 at 0.67.  (source: various, accessed 2024 EPA EnviroAtlas).
