<div style='text-align:Left;font-size:12pt'><div><p><span>This service represents existing and proposed WSDOT noise walls along Washington state routes and is symbolized based on the highway direction of travel. Noise walls are free-standing barriers built parallel to a highway. They are usually found near public areas, such as parks, and residential areas. The walls range in height from 6 to 20 feet, but are normally 12 to 15 feet tall. They can reduce noise levels by 10 to 15 decibels, cutting the loudness of traffic noise in half. Barriers can be formed from earth berms, or constructed of wood, stucco, concrete, masonry, metal, or other materials. This feature class contains existing Type I and Type II noise walls and proposed noise walls.</span></p></div></div> |
