Existing Socal Aircraft noise impacts

By request I created this map of existing (pre-NextGen) noise impacts from aircraft in the SoCal study area. Uses are to compare what you’re hearing against the FAA’s modeled baseline. For noise impacts due to proposed SoCal NextGen refer to : Total noise impacts Change in noise impacts Disclaimer: This map only contains those flight …

Improper Baseline used to determine impact

Over the City of Culver City, the levels of impacts stated by the OAPM EA to support their finding of No Significant Impact are based on comparing the proposed new flight paths to a “no action” alternative. The “no action alternative” is based on current flight patterns — assessed as of December 2012, and projected …

SNA: Orange and Newport Beach impacts

The Change in Noise map I created shows the intensity of noise changes. This is just a quick post to show how the map can be used to inform what you’re seeing in the Google Earth data. I ran across some EA comments by Tabor Law for their clients AirFair out of Newport Beach. In it they question the dispersion …

Change in Noise over Residences-map

Following is the second part of the proposed changes noise mapping- How noise will change in each census block in the SoCal Metroplex. I’ve already mapped the total aircraft noise map here. Firstly, the FAA did provide this disclaimer about the use of this data: “This information is provided for informational proposes only and is not intended for …

Total Aircraft noise over Population map

I’m still wading through the data the FAA team has given us. Some of my initial comments to the EA team were that we needed the noise data, waypoint coordinates and.. that it’d be nice to have the Google Earth flight track data. The feedback I got back then was that was asking too much. …

Specific Comments about RNAV and the Socal Draft EA

Specific Comments about RNAV Implementation and the Socal Metroplex Draft Environmental Assessment. The central community issue with the FAA’s implementation of RNAV flight paths is they take wide dispersed flow of aircraft paths and focus them into a concentration of flights around a centerline. The modeling needs to accurately reflect the anticipated noise impacts from the proposed changes …

The Persistent CLIFY

This weekend I sat down with the newly released KML and way-point data from the FAA. The new authoritative “TARGET” way-point data allowed me to confirm my coordinates and there were no surprises there. Once I loaded up the new flight track KML on top of my authenticated flight tracks I got a bit of a surprise: …

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 …

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 …

The Culver City Flight Paths

Two major aircraft arrival flight paths to LAX fly over Culver City and the FAA proposes changing their heights and positions. The FAA redesign of Southern California airspace is to take advantage of NextGen satellite navigation. Over 109 new satellite procedures propose to increase airspace efficiency and reduce complexity to flights arriving and departing at 16 …
