Traffic noise was studied along I-494. Specific results for the noise analysis is available within the Noise Report (see EA appendices).
Noise barriers are solid obstructions built between the highway and properties along the highway designed to reduce the noise level of vehicles. Barriers can be either berms or high vertical walls. Constructing a noise wall must be feasible and reasonable. Feasibility and reasonableness are determined by cost, amount of noise reduction, safety, and site considerations.
Traffic noise along I-494 between East Bush Lake Rd. in Edina and 12th Ave. North in Richfield exceeds the state and federal noise standards at some locations. A noise study concluded that five noise walls along I-494 between Edina and Richfield would meet the necessary criteria to reduce noise for properties adjacent to I-494 by at least five decibels. The proposed noise walls are 20-foot tall structures built with concrete panels and posts.

Noise wall voting
MnDOT sent notices and noise wall ballots to people who were eligible to vote. Only the property owners or residents who experience a noise level reduction of at least five decibels from the proposed noise walls could vote on the walls.

More information about noise wall voting
Property owners and residents who will experience a noise level reduction of at least five decibels can vote for or against the noise wall that provides the noise reduction.
Who is eligible to vote on whether a noise wall should be constructed?
MnDOT will send notices and noise wall ballots to people who are eligible to vote. Only the property owners or residents who experience a noise level reduction of at least five decibels from the proposed noise walls can vote on the wall.
How does voting work?
If 50 percent or more of all possible voting points from eligible voters are received after the first request for votes, the majority of votes (based upon the votes received) determines the outcome. If less than 50 percent of the possible voting points for a wall are received after the first request, a second ballot will be mailed to the eligible voters who did not respond.
If 25 percent or more of all possible points for a wall are received after the second request for votes, then the outcome is determined by the majority of votes received. If less than 25 percent of total possible points for a noise wall are received after the second request for votes, then the wall will NOT be constructed. If there is a tie, where there are equal numbers of points for and against a noise wall, the noise wall WILL be constructed.
What happens if I didn't vote?
If you don’t vote, the voting points assigned to you do not count for or against the noise wall.
How are the votes counted?
MnDOT uses a weighted voting system. Points are determined by how much your property or unit is affected by the noise wall and whether or not you own the property or unit. If a noise wall is voted down, it will not be reconsidered.
