ss HIAWATHA MARKETING, INC. 3100 JOHNSON STREET N.E. MINNEAPOLIS, MN 55418 (612) 789-2995 February 16, 1999 Mr. Cary Teague City of New Brighton 803 5th. Ave. N.W. New Brighton, MN 55112 Dear Mr. Teague 4111 As you know, our site plan that we submitted to the city for the rebuilding of the Tank-n-Tummy convenience store includes a car wash. You have expressed a concern about the noise level created by the car wash dryer when the bay doors are open and the dryer is running. In addressing this possible problem, we discovered that a dryer is available with new technology that allows for a noise reduction package. It greatly reduces the decibel noise to a very acceptable level. If our plan is approved, we will be using this model for our car wash. Also, I have proposed that we will shut down the car wash between 11:00pm and 5:00am. To give you an idea of the possible noise level of our updated car wash dryer, the enclosed "Dryer Noise Emitting Test" conducted by Superior Car Wash Systems, Inc. shows that the ambient noise level at 80 feet from the dryer to be 67 dba. It also states that the ambient noise levels of street traffic to be 65 dba. On our proposal, the distance from the dryer to the curb line is 95 feet. This would make the noise level at the curb line to be approximately 66 dba. The distance from the curb line to the house directly north from our property is approximately100 feet. Ifyou reduced the 66 dba one point for every 10 feet, the noise level at the house would be approximately 56 dba.
