HYM told us several times that they will call meetings when they have firmed up which lot(s) will be next. The parking lot (known to Sierra+Tango residents as Lot U) *can* be relocated (more specifically, folks' parking spots can be relocated) within a certain, relatively short radius from our buildings. However, at our last meeting, HYM suggested that Lot U - if it's ever built upon - could be one of the last lots to receive a non-parking tenant: after the theater complex (tentative) and the Lechmere rebuild (once the station is razed and first street extended).
In other news, the firm said the most likely new construction will probably be across from Sierra: the mirror image condo (likely) buildings near the water. And the plans for the other building - built to suit - near Twenty|20 were coming along with two potential tenants. Finally, S+T residents received a flyer just before the holidays that suggested Avalon's Phase III would finally rise in 2015, with construction potentially beginning this spring. Its location will a filthy hole, so booyah (folks on the OBrien side of our buildings mightn't agree).
Of course, things could change. Ha.
