An environmental review says that Facebook's plan to build three 75-foot-tall buildings, adding 962,400 square feet at two proposed office buildings and 174,800 square feet at a 200-room hotel, plus 3,533 parking spots, could have some impacts determined to be "significant and unavoidable."
The new buildings would be constructed at the current 58-acre TE Connectivity location bounded roughly by Constitution Drive, Chilco Street and Bayfront Expressway after what's currently there is demolished. Compared with what exists there now, the new development would add 121,300 square feet of space.
The new office buildings, combined, could accommodate about 6,400 employees, the report said. The hotel would likely employ about 150 people. All three buildings are estimated to generate about 6,550 employees.
To mitigate traffic impacts, Facebook would set a trip cap and establish a transportation demand management program.
That trip cap would limit the number of trips allowed during peak traffic hours and set an overall limit for the number of trips allowed per day at the three proposed buildings Buildings 21, 22 and the hotel plus its recently completed Building 20 and the now-under-renovation Building 23.
Still, adding new buildings and jobs to the site is expected to have some traffic impact, particularly on the already choked arteries that lead toward the Dumbarton Bridge and U.S. 101.
In the near term, a cursory count showed the project could have 10 areas of "significant and unavoidable impact," related to traffic, and 19 by 2040.
"Significant and unavoidable" impacts, applied to traffic in this context, means that measures that would keep traffic "wait times" from increasing past a certain level are considered not feasible. That level or threshold, however, can vary based on the intersection and current traffic conditions.
At some intersections, where traffic is already heavy, those thresholds are set by the city to be crossed whenever there will be an added delay of 0.8 seconds or 4 seconds.
Facebook (under the name "Hibiscus Properties, LLC") also proposes to build a multi-use bike and pedestrian bridge over Highway 84 to connect eastern Menlo Park to Bedwell Bayfront Park and the San Francisco Bay Trail, with public open space and additional bike and pedestrian paths.
