Title R930 - Preconstruction
Rule R930-3 - Highway Noise Abatement
Section R930-3-12 - Construction Off Right-of-Way
Current through Bulletin 2024-06, March 15, 2024
Normally, noise walls built pursuant to this rule will be constructed within Department right-of-way and owned and maintained by the Department. There are cases in which Department right-of-way is not the most prudent location for noise barriers, yet noise abatement is still feasible and reasonable if built on adjacent property or adjacent public right-of-way. In these cases:
(1) The Department's cost is limited to normal cost for abatement on Department right-of-way.
(2) In no case shall the Department construct a noise barrier unless the adjacent property owners allow access and easements as necessary in order to construct and maintain the barrier.
