In late in 1970’s, the Port made an agreement with the FAA air traffic controllers to change the departure track from 270 (bottom dashed line) to 290 (middle dashed line) for departures 10 pm to 6:30 am. That was referred to as the 290 nighttime noise abatement agreement. Those housing units close in to the end of the runway experience the highest single event noise levels.
At that time there were two different federal laws that mandated evaluation of changes in flight departure tracks to ensure that noise was not being shifted from one housing tract to another. While the distance the track is moved is small, there is still a substantial noise shift. This was, I believe, intended to be a temporary noise relief measure
