The Subject Property is located in a predominantly residential area of Marina Del Rey at the east end of Bora Bora Way. Five underground storage tanks (USTs) are located on the south side of the Subject Property beneath a concrete slab. Fuel is supplied to the dispensers via underground piping and piping suspended beneath the boat docks.
The Subject Property was originally developed as a fuel dock facility in the early to mid-1960s. A series of subsurface investigations and groundwater monitoring well installations were performed from 1991 to 1997. The original USTs were removed in 1994. Data from previous investigations indicates the groundwater in the vicinity of the current and former USTs was impacted by petroleum hydrocarbons and fuel oxygenates.
