In the Press Herald today, Redfern has filed an application to the MDEP regarding beneficial use of construction soil from the Washington Ave site to 115 Lancaster and 103 Chestnut. Interesting.

I don't understand...
 
Redfern owns the building lots at 115 Lancaster and 103 Chestnut which are contaminated with high concentrates of metals due to a former junkyard and other former businesses. To build on these lots, they will need to do a Vrap which requires fill. So, looks like that they will start construction on the Washington ave lot, use the construction fill from the site and use it by spreading it on the other two lots to make it able to construct
 
I think Redfern also needs to raise the ground floor elevation on the Lancaster Street parcels in order to mitigate flooding risks – which is why you see steps leading up to the building entrance on the renderings.

Banks won't finance a building that's expected to be below the high-tide line before the end of the mortgage's term.

Storing fill on the Lancaster Street site might also help "preload" the clay soils under Bayside, which are going to pose a challenge to tall buildings here:
