The original plan for the infrastructure of the Great Park was virtually identical to Newport Center, with five roads connecting into a central loop road separating the park into "blocks". The design was later modified to include a large section of runway and conform more to the layout of the original base, as a reminder of its history. Most prominent in the park plans is the restoration of Agua Chinon Creek, which had been channeled underground ever since the base was built in the 1940s.
