said it would be virtually impossible to have a vegetation barrier in Minnesota and
explained that a mass is required for energy loss and would necessitate 32 lbs. per
square foot, and that trees could not be planted that close together in Minnesota,
although it was accomplished in Florida.
Craig Herrington, 2076 Terrace Drive asked what the cost of the wall would be. Mr
Orlich replied that the cost would be approximately $5 per square foot, with a total
cost for the whole project of approximately $250,000, which would include material,
labor, landscaping and maintenance.
Mr. Pittman asked how much sound would be stopped for Raymond Avenue. Mr. Orlich
replied that Raymond Avenue is higher than the surrounding area so that while the
tire noise would be cut, the truck noise would not be lessened a great deal.
Dale Schobu identified himself as a resident of the trailer park and stated that he
would definitely benefit from the noise barrier, as well as all his neighbors in the
trailer park. He stated that while he did not plan to be a permanent resident of
the trailer park, that whoever bought his trailer from him would also benefit from
the barrier.
Mr. Buckingham asked how many people were in favor of the barrier.
Mayor Pickar replied that both the trailer parks were in favor of it, and that 16
homes were surveyed, of which 8 were in favor of it, 4 were against it, and 4 did
not respond or were not available for questioning.
Mary Lou Pittman, 5379 Raymond stated that she felt if the noise barrier were put u
it would box in the people in the trailer parks and cut off their air circulation.
Mr. Orlich replied that concern had been expressed for the trailer park residents,
who would be most affected by the barrier so two meetings had been held previously
and he had taken copies of the plans to the trailer parks for the residents to
examine. He also stated that the noise level would be lowered approximately 10
decibles, which Councilmember Ziebarth pointed out would cut the noise level almost
in half.
Mr. Orlich stated that the noise level improvement would decrease as a person travelled
away from the barrier, but that neighborhood noise also had to be taken into consi-
deration and that absolute quiet could not be achieved. He also stated that the
reason the barrier was being put up was that it had been ordered by the Minnesota
Legislature, and that the Mounds View location was selected as it was found to be
one of the areas that needed it most. The noise level there is presently in the
mid-70 dPcible level avd the bar rier would lower it t o the mid-60's,
Mr. Buckingham asked the feasibility of putting down a layer of asphalt to cut the
noise. Mr. Orlich replied that testing had been done across the country and the
most the noise level dropped was two to three decibles, and that while the noise
seemed to lessen to those riding in a car on the asphalt, it actually did not Jesse
the outside noise. Additional research is being done with the asphalt, but it does
not stay down on concrete, especially in Minnesota.
Mayor Pickar asked what the feasibility was of transparent walls.
