Molin Concrete page 10 Subp. 2. Noise standards. Noise Area Classification Daytime Nighttime L50 bio iso L10 1 60 65 50 55 2 65 70 65 70 3 75 80 75 80 As can be seen from these definitions, a test must be able to determine if the specified decibel level is exceeded for 10% of the time for one hour, or for 50% of the time for one hour. Daytime in defined as 7:00 am to 10:00 pm, night time as 10:00 pm to 7:00 am. Residential land use is in Noise Area Classification 1. The measurements are to be taken at the location of the receiving use: in this case, the residential property. That is, noise generated by one use should not exceed the limits when measured from the other use. Molin had a noise measurement analysis performed in October 2000 by Wenck Associates. The readings indicated no violation of MPCA noise rules during those times. MPCA did state in a conversation with City staff that if a test is conducted by established methods, MPCA typically accepts the results of the test. Neighbors are not satisfied by the Wenck analysis. Staff contacted the MPCA to see if MPCA could conduct the analysis. This is possible, but there is a waiting period of several months. Instead, the City hired a noise analysis consultant to perform another analysis. The new analysis is underway. Measurements can be affected by wind and rain, so the measurement days are weather dependent. Staff hopes the results will be available for the October 22 City Council meeting. FINDINGS FOR CONDITIONAL USE PERMIT As stated in Section 2 Subd. 2.B.7. of the zoning ordinance, The Planning and Zoning Board shall recommend a conditional use permit and the Council shall order the issuance of such permit only if it finds that such use at the proposed location: a. Will not be detrimental to or endanger the public health, safety, comfort, convenience or general welfare of the neighborhood or the City. b. Will be harmonious with the general and applicable specific plans and policies of the comprehensive plan of the City and this ordinance. c. Will be designed, constructed, operated, and maintained so as to be harmonious and appropriate in appearance with the existing and/or intended character of the general vicinity and will not change the essential character of that area.
