New development permits are seeking the construction of an additional 800+ multi-family units and commercial space in a site bound by Altino Boulevard, Hillsdale, and the Union Pacific railroad. KB Home South Bay would be the developer and it would span 140 acres.
Phases 3 and 4 of Communications Hill are supposed to include a mix of single-family detached homes, townhouses, and flats. The current scope of the project would include 505 homes, hundreds of apartment's across several five and six-story buildings, up to 32,873 of commercial/retail space, and 16,215 SQFT of amenity space.
There is already quite a bit of traffic along 87 due to Communication Hill so it will be interesting to see how well the expansion can be accommodated.
