This property contains two parcels and encompasses an entire city block. Historical documentation from 1901 depicts the site developed with several residential structures and the Washington Gas Company, a manufactured gas plant (MGP). The MGP site, which operated under several different names over the years, operated from approximately 1857 through 1947 when the plant was converted to propane. Gas storage tanks are visible on historic aerial photographs up until 1958. Between 1964 and 1974, the remaining residential properties were razed at which time the site was occupied by the former Dr. Pepper Plant on the northern portion of the property. All onsite structures were razed around 2006. Historic MGP operations have contributed to soil and groundwater contamination at the site and the property is listed as a State Hazardous Waste Site. In 2007, impacted soils in the area of the former MGP site were excavated and disposed offsite. The excavation area was greater than 2,500 square feet and multiple subgrade structures formerly used in MGP operations were uncovered and removed. Groundwater monitoring wells present at the site are presently sampled semi-annually to document groundwater quality as it pertains to the site. Historical documents reviewed during the performance of a Phase I Environmental Site Assessment indicated that soil and groundwater quality on the portion of the site associated with the former MGP site had adequately been assessed and/or remediated.
The City of Washington expressed interest in redeveloping this property with a new police station and other possible municipal building. In July 2019, Mid-Atlantic conducted additional soil and groundwater assessment to provide analytical data to determine if engineering controls would be necessary to safely develop and occupy the site and provide the North Carolina Superfund Program and Brownfields Program the information they need to regulate the project. Following completion of the Phase II Environmental Site Assessment in July 2019, interpretation of the analytical data indicates soil and/or groundwater contamination is present on portions of the site not historically utilized by the MGP site. However, these constituents should not pose an impediment to future redevelopment of the site.
With the assistance of Mid-Atlantic, the property was deemed eligible for the North Carolina Brownfields Program (NCBP) and the City and the NCBP are currently in negotiations to finalizing a Brownfields Agreement for the property. Once filed with the property deed, a finalized Brownfields Agreement offers the City liability protection in redevelopment and reuse of the site. Redevelopment plans for the site are still under development; however, a preliminary schematic of the proposed redevelopment is attached.
