If you are indeed involved with changes in Montgomery County, why don't you give us a full account of what is happening. Area residents only ever heard about Palisades, but some of the most significant changes in southflow operations are in Montgomery County. Strangely, there was never anything in the news. Here's my summary (excuse the typos):
2016 - The FAA consolidates all the flight paths for arrivals located primarily in Virginia and moves them to the Potomac River and Montgomery County. The waypoint FERGI is moved to Potomac near Avenel Country Club. A Reagan National Community Noise Working Group (established in October 2015) votes in favor of the new approach procedure. Montgomery County is absent from the vote.
Montgomery County files a lawsuit against the FAA. The lawsuit is thrown out of court not because of merit but timeliness.
Potomac residents on the Noise Working Group ask the FAA to relocate FERGI further north to areas with less population density. The FAA rejects the idea as not being operationally viable. The FAA is then asked if it is possible for the arriving airplanes to start their final descent at DARIC in Glen Echo i.e. over the river instead of FERGI irrespective of population density.
Montgomery County hires an independent consultant to design a flight path for arrivals at DARIC. The consultant is asked to disperse the flights over Bethesda and Potomac in an effort to decrease channelization over FERGI. (TAA Concept refers to the dispersal).
The new design is submitted to the FAA for review and approval. Pages 16 & 17 show before and after.

The FAA examines and amends the proposal submitted by MoCo by moving waypoint DARIC west (referred to as new Daric) and away from Glen Echo to make the flight path feasible.
2021 - 2024 - TAA (dispersal) is being tested in Montgomery County with about 10 percent of the fleet. Complaints from unsuspecting MoCo residents pour in to MWAA.
As part of the re-design, the Working Group gives the FAA the green light to introduce the GPS procedure for arrivals. The FAA has been seeking this approval for some time. The new flight path has lower weather minimums which means the inclement weather procedure (LDA-Z) does not have to be used as often.
2022 - The FAA presents to the Working Group the final design of the new flight path for arrivals. Concerns are raised that the new route is closer to communities in the District. The FAA responds that this is the only option. The key benefit of the new procedure for the Palisades is that in inclement weather there will be fewer overflights.

In Montgomery County the plan is to expand TAA (dispersal) from 10 to 50 percent of the fleet and to begin the inclement weather procedure at DARIC instead of FERGI.
Also: The inclement weather procedure is temporarily suspended for several months. The runway is also being repaved which means fewer flights late at night and early in the morning until October 2024.
