The Planning Commission had previously considered the car wash proposal at a p ublic hearing in December. At that time, they asked the applicant to provide additional information related to noise, parking, grading and drainage, landscaping, and design of the building. Bill Costa, the applicant, provided information related to noise, reviewed the revised site plans and presented alternatives for building design. The Planning Commission was favorable to the noise study information (see attached) and the site plan changes. Revised landscape plans were provided and are subject to City Arborist review and approval. Mr. Costa also provided alternatives for the building elevation facing Highway 5. The Planning Commission recommended the third building elevation option with better corner detailing and a lower, more consistent parapet height and design on all sides of the building. The Planning Commission recommended the car wash project with the following conditions: 1. The City Council approves the preliminary and final plat for Lots 1 and 2, Block Jacobs 2 Addition. 2.

In order for sound to be transmitted or propagated, it re- quires an elastic medium. The most common medium for transmission is the air. Such sound is called "air - borne sound." However, sound can also be easily transmitted through common building materials and components such as steel, concrete, wood and metal framing, piping, and gypsum wallboard. This type of sound is called "structure -borne sound." A• weighted decibel IdB(A)] is a standard single- number rating representing the overall sound energy of a given source. The A-weighting network in a sound level meter filters sound in a manner similar to the human ear by downgrading low frequencies.

Rosenberg, AIA; Accentech Inc.: Cambridge, Massachusetts DECIBEL SCALE The decibel (dB) scale is a logarithmic scale based on 10' times the logarithm of a ratio of sound pressures. The decibel levels of two noise sources can not be added directly; instead use this simplified method: difference between two sound levels, in dB add to the higher level For example: 90 dB + 20 dB = 90 dB 60 dB + 60 dB = 63 dB OCTAVE BAND An octave band covers the range from one frequency (Hz) to twice that frequency, f to 2f.
