Once out they tested the soil in the hole where the tank came from for indications of fuel in the soil.

Luckily, we knew a plumber and were able to install a sump pump system that drained out to the alley (a ton of hard work - digging a 3 ft deep trench 50 yards in the classic baltimore rocky soil).

A TIC is a unique structure for holding property in that while we technically had our own units (our building was built as a over under duplex with a soft first story (garage and storage areas and services (furnaces) underneath the 2nd floor living unit with 3rd floor living unit on top. 

During the inspection, they found an underground oil tank with contaminated soil on the premises.

I've got a lot of other contacts for GC's, Architects, subs, permit expediters, Geo/ Soils, Zoning attorney's, ADA ramp plan engineers, structural engineers, you name it related to new construction in Philadelphia.

I'm thinking about pushing the soil back, and simply exposing the lower floor. 

I would also buy new trays that go underneath , its easier than cleaning .

With that mind...2. the water from the roofline then drops to soil right on the ground used for landscape plants.

It was worse than our native soil!
