2009 | Designed as part of a larger corporate campus master plan for BP. Its design includes a right hand bus apron for pick up and drop off of employees and visitors by shuttle buses, tour buses, and school buses. The leg to the west is intended to serve a future mixed use development. While the ICD may seem larger than it needs to be from a functionality standpoint, the size was intended to accommodate landscape architecture and placemaking elements. |

In the future Chauncey will continue to the east and a fourth leg will be added. |
