	For projects with noise impacts where noise abatement is both reasonable and feasible, a noise wall public meeting is required. If project timing allows, this meeting can be combined with other project public meetings. Required invitees for this meeting are all first-row and benefitted receptors. However, a meeting with non-qualifying impacted area residents is sometimes beneficial. Meeting with different groups of residents can be combined where appropriate.

	:1. Viewpoints of owners and residents of the benefitted receptors will be obtained. These will usually be obtained through mailings or a public forum. The viewpoints of non-owner residents will be evaluated as a portion of an aggregate of 25 percent of the total. The viewpoints of owners will be evaluated as a portion of an aggregate of 75 percent of the total. For noise abatement to be considered reasonable, over 50 percent of the aggregate response must be in favorable.		:1. Viewpoints of owners and residents of the benefitted receptors will be obtained.

	:2. Noise abatement measures shall not exceed ~~an all-inclusive cost~~ of $36,000 per benefitted receptor (e.~~g. materials, right-of-way, mobilization, installation, traffic control~~, and ~~relocates). Coordination with and approval of FHWA is needed prior to incorporating any unanticipated costs. This~~ cost shall be recalculated at an interval not to exceed every 5 years.		:2. Noise abatement measures shall not exceed 1,300 square feet per benefitted receptor, in the case of noise walls. Where noise walls are not options, other noise abatement techniques may be considered, but cannot exceed $36,000 per benefitted receptor. In order to ensure that the noise abatement parameters remain current, the wall area limit and cost per benefited receptor shall be recalculated at an interval not to exceed every five years. The updated values may not be used to analyze noise abatement calculations from previous years.

	:3. Noise abatement measures must provide a benefit of a minimum of 7 dBA for 67 percent of benefitted first-row receptors.		:3. Noise abatement measures must provide a benefit of a minimum of 7 dBA for 67 percent of benefitted first-row receptors.

	For reasons of safety (primarily wind load and clear space concerns), noise walls are limited to a height of 20 feet. This criterion alone cannot be used to consider noise abatement unreasonable.

	Third party funding cannot be used to make up the difference in cost between the reasonable cost allowance and the actual cost. Third party funding can only be used to pay for additional features such as landscaping, aesthetic treatments, etc. for noise barriers that meet cost-effectiveness criteria.
