Page "Maywood Park, Oregon" Paragraph 10

Maywood Park insisted that the freeway and access roads be sunken below grade to lessen the impact of vehicle sound.

The freeway was sunk a great deal from its original planned grade.

The city also demanded a large wall called a sound berm to be installed on the border of the freeway, which the state agreed to.

And finally, the residents pleaded that “ Every tree that can possibly be saved must be saved .” And so, in came the construction crews.

The lower grade of the freeway has been the most successful sound limiting factor.
