The Trillium Landing Senior Living facility will feature a three-story building with 1, 2, and 3 bedroom apartments, office space, mechanical room, laundry, storage, public spaces, parking, and other ancillary areas. The proposed site is in the Mendenhall Valley Vintage Business Park within the City and Borough of Juneau. The proposed facility is a 45,000-sf, three story, timber-framed structure.
The geologic setting of the lower Mandenhall Valley can be generalized by older marine deposits at depth underlying younger glacial outwash deposits from the Mendenhall glacier. Near-surface soils at this site consist predominantly of young glacial outwash deposits.
