- Harrison Elementary School Soundwall
- The soundwall would be constructed at the School's north property line adjacent to the sidewalk on the south side of Marengo Street. Accounting for the gaps in the barriers, the proposed soundwall would be approximately 630 feet in length and consist of a combination of rigid soundwalls (i.e., masonry, or other solid barrier system such as post-and- panel) and somewhat less permanent and massive noise barriers (i.e., flexible, mountable sound "blankets" or malts). The soundwall would range in height from approximately 6 foot 7 inches to 7 foot 11 inches (for the mountable noise barriers) to approximately 15 foot 5 inches (for the rigid soundwalls) above local ground. The only exception is at the easternmost rigid soundwall. This portion would vary in height, because it would be constructed underneath the overhead pedestrian bridge.
