Airport Noise and Property Values

"The Congress declares
that it is the policy of the United States
to promote an environment for all Americans
free from noise
that jeopardizes their health or welfare."
NOISE CONTROL ACT of 1972

What happened to that act? How was it so thoroughly destroyed in the past 43 years? airportnoiselaw.org is an excellent reference site that studies the effects of airport or aviation noise activity on residential properties. The site is well worth perusing. One recent study in the Los Angeles area showed that property values underneath noisy flight corridors reduced property values by as much as 28%.
