The Brooklyn Park City Council is expected to vote tonight to approve an outdoor Amphitheatre project for the Minnesota Orchestra. The 19-thousand seat amphitheater would host about 50 summer concerts. Eighteen would be orchestra performances, the rest would be pop music. But whether it's Pachobel or Prince, neighbors are concerned it'll be just plain noisy. Brian Timerson handles noise problems for the Minnesota Pollution Control Agency. He says any amphitheater will probably require special permission to exceed legal noise limits.
