Service Description: Rutgers updated a portion of an analysis completed in February 2017 of Industrial and Commercial facilities and flooding (Original Analysis). This updated analysis includes 4 types of sites with hazardous substances/materials including: Known Contaminated Sites List (KCSL), Community and Worker Right to Know (CRTK), Toxic Catastrophe Prevention Act (TCPA), and Discharge Prevention Control and Countermeasures (DPCC). These site point files were developed by NJDEP and available on the Open Data Portal. Flooding data used in the analysis includes FEMA Effective and Preliminary Flood Hazard Zones and Total Water Level estimates for future flooding developed by NJDEP and Rutgers. The GIS analysis was completed using Python coding and determined if the sites are in any of the flood zones. Spatial analysis of vector flooding data used the Select by Location tool and the analysis of raster flooding data used the Extract by Location tool. The final files are copies of the original hazardous site files developed by NJDEP with additional attribute fields added having 0/1 format to identify if the site is in each flood zones. These additional fields were combined and evaluated. The analysis considers “current flooding” risks to be the combination of the FEMA Effective and Preliminary Flood Hazard Areas and the 5 ft TWL MHHW. “Future flooding” is the 7 ft TWL MHHW that is not in current flooding. In addition to flooding, the analysis identified if the sites are also in block groups that are Overburdened Communities (OBC) under the New Jersey Environmental Justice Law (EJ Law) . The results found that potential impacts from current flooding ranged from a high of 38.8% for DPCC sites to a low of 26.3% for CRTK sites. Future flooding impacts were lower and from 2.3% of sites for TCPA to 0.4% for DPCC. The OBC analysis found the percentage of sites potentially impacted by current flooding that are also located in an OBC ranged from a high of 84.9% for DPCC sites to a low of 70.8% for TCPA sites.
