Are the Airspace changes good or bad for Culver City?

I was asked recently if the changes to the airspace are Good or Bad to Culver City. My answer, which we discussed at the last Culver City meeting about NextGen impacts, is “Yes, No, and We won’t know until its implemented”. The FAA has a summary of potential benefits for the entire airspace and Culver City’s changes …

Proposed flight path undermines LAX Noise Abatement efforts

The proposed LAX BIGBR STAR replaces the BASSET and REDEYE conventional procedures. I am concerned about the increased noise impact that lowering the altitude 12.5% over residential areas will cause. UPDATE 9/2/2016* The proposed LAX MDNYT STAR will replace REDEYE for Over Ocean Operations. It is unclear from the Final EA whether the new CLIFY …

Culver City community meeting

The City of Culver City will be having its 2nd community meeting regarding LAX overflights. The meeting consists of a Community discussion and a panel about the FAA’s SoCal MetroPlex’s (NextGen) project and the flight path impacts over Culver City. I will join council members Jim Clarke and Meghan Sahli-Wells in the City Council Chambers on Thursday, …

Meteorological effects change sound propagation.

Local and Seasonal Meteorological differences change sound propagation. Sound propagation is affected by atmospheric conditions. The FAA’s Environmental Assessment(EA) assumes a homogeneous atmosphere with a single temperature, humidity level and pressure. This doesn’t correlate with real-world conditions. Southern California is subject to persistent meteorological effects, such as inversion layers and prevailing winds. Temperature and humidity are …

Supplemental noise metrics can help public understand changes

The use of noise Metrics other than DNL can better tell Communities how airspace changes will affect them. Design of airspace is also a design of noise on the ground and communities needs to be involved in these decisions. People living under a flight path may experience a deleterious effect on their health, negative impacts on …

Average weather calculation does not represent Noise impacts from overflights

Single factored Environmental variables do not adequately represent climate across the diverse SoCal area. Temperature and humidity change how sound propagates. Noise effects borne by differing meteorological characteristics are not modeled correctly resulting in average noise values being incorrect up to .6dB near airports. The Southern California Study Area is over a large and diverse …
