Voluntary Noise Acquisition Program

In 1985, the MAA began a program to acquire residential properties with cumulative noise levels of 75 Ldn or greater.  In 1988, the MAA completed a Federal Aviation Regulation Part 150 Study and expanded the program to homeowners residing in communities that were exposed to cumulative noise levels of 70-75 Ldn.   Properties which were determined to be impacted, became eligible for federal noise mitigation funds. Property owners, who volunteer to participate, were paid fair market value for their property at its highest and best use, and were provided relocation assistance. Properties located in areas whose day-night average sound level (Ldn) was greater than 70, as determined by Airport Noise Zone contours, were eligible for this program provided the property has been zoned by local government to transition from residential.

Progress as of March 31, 2008

  Eligible properties 343
  Properties acquired to date 250

School Sound-Proofing Program

The school sound insulation program was completed in 1991 by providing sound insulation at four schools which were re-furbished to reduce interior noise levels. The total cost of the program was $9.3 million.

Relocation of Ridgewood Mobile Home Park

In August of 1998 the MAA began the relocation of the residents of the Ridgewood Mobile Home Park. The Park was located within the DNL 65 contour, as determined by the 1998 Airport Noise Zone. The Park land was purchased at a price of $6.35 million for 72 + acres. 122 families resided in the Park at the time of MAA’s purchase; there were a total of 140 mobile homes in the Park. The program was completed in March 2000 at a total cost of 9.7 million.
