52 11. RESPONSE: Correction of Section 5.21-6. 1) Correction of 5.21-6 to reflect the following: Need to reinstate paragraph A of old ordinance. "A decibel is a measure of a unit of sound pressure. Sound waves having the same decibel level "sound" louder or softer to the human ear depending upon the frequency of the sound wave in cycles per sound (i.e., whether the pitch of the sound is high or low). Thus, an A-weighted filter, constructed in accordance with the specifications of the American National Standards Institute (ANSI), type II meter which automatically takes account of the varying effect on the human ear of different pitches shall be used on any sound level measurements required by this section. Accordingly, all measurements are expressed in db (A) to relect the use of this A-weighted filter. The meter shall be calibrated in accord with ANSI before and after testing." 2) The chart heading should read as follows: Maximum Permitted Equivalent Sound Levels db (A). 3) In the current note A, the following changes should be made: Paragraph 1: (leg) changed to (Leq) and this sentence added to the end. "The readings may also be obtained using a type II intergrating sound level meter over a 17 minute period." (This meter gives digital read-outs every 10 seconds.) Mr. Bill Plummer, Planning Board member, stated that a certain hour should be specified in the ordinance to consider the noise level. Mr. Manuel Kiser questioned the rights of the property owner when a complaint is made against him regarding noise. Mrs. Yvonne Furr, developer of new race track in the county, complained that the noise regulations in the ordinance were enacted specifically in regards to the race track and requested clarification of the noise provisions of the ordinance and the way in which the noise levels are to be checked. UPON MOTION of Commissioner Payne, seconded by Commissioner Lentz and unanimously carried, the Board tabled Amendment 11. UPON MOTION of Commissioner Cook, seconded by Commissioner Lentz and unanimously carried, the Board agreed to refer the tabled amendments of 3, 9, and 11 back to the Planning Board. Ms. Rosemary McLean, member of the Planning Board staff, reviewed proposed amendments to the Zoning Atlas. These amendments were proposed to correct errors which had occurred during remapping during preparation of the Atlas. The proposed Zoning Atlas Amendments were as follows. 1. Map 5623 a proposed zone change from R-7.2 to C-2 in Kannapolis (PIN's 6000, 4467, 2640, 4550). 2. Map 5613(15) a proposed change from C-2 to RMF-6 in Kannapolis (PIN's 0837, 0753, 0609). 3. Amendment to include previously omitted maps: TWP 11: 5529; 5529(09); 5529(16); 5539(13)~ 5529(12); 5539(09) No one spoke either for or against these proposed amendments. UPON MOTION of Commissioner Lentz, seconded by Commissioner Payne and unanimously carried, the Board adopted the Zoning Atlas Amendments as recommended. Mr. Mmnuel Kiser commended the Planning Board for their work regarding the proposed amendments and stated that confusion existed among the members regarding the recommendations because the minutes of the last Planning Board meeting had not as yet been made available to the members. Chairman Bonds adjourned the public hearing at 10:35 P.M. He recon- vened the regular meeting of the Board in the Commissioners' Meeting Room at 10:50 P.M.
