Dickey-Lincoln School Lakes Project

The overall project area can be described as a very quiet natural area remote from any major industrial activity, but subject to high traffic noise levels along the main road. Noise sensitive areas consist of low density residential areas in the villages and widely spaced residences along the main road. The estimated yearly average Ldn for all noise sensitive areas 1s 60 dB due to the close proximity of traffic to all residences. The yearly average Ldn decreases to 40 dB at 600 ft from the main road, and to 30 dB 1n the timberland areas.
