Water purifiers cannot be built (regardless wheter or not the player has the Wasteland Workshop add-on installed) since the settlement radius doesn't extend to the water, so only pumps can be used to provide a water supply. Crops cannot be planted at all, garden plots cannot be built so food cannot be supplied even if Wasteland Workshop has been installed. No recruitment radio beacon can be built, so no settlers will join. No guard posts can be built, so the only method of defense is building turrets. Nor is it possible to build any stores, scavenging stations or artillery pieces. Therefore, there is little purpose or practicality in building a settlement here. There is plenty of flat surface within the radius, which can allow for large buildings to be constructed without obstruction. That being said the area could be built up by the Sole Survivor into an exclusive settlement located right beside Boston Airport.
