2 Staff has attempted to outline the items that the Board of Adjustment needs to consider as part of making the determinations. The Board should discuss each of these items and ask questions of the Applicant and/or Staff as needed. Mr. Al Jansen and Mr. Moe Wiepjes (Canadian Solar Staff that assisted with site visits) and Mr. Al Benshoff will be at the March meeting to answer questions related to the site visit and/or the materials submitted. Summary information is as follows: NOISE AND NOISE WALL (INFORMATION PROVIDED PREVIOUSLY/SEE SITE PLAN) The original application stated that sound levels generated by the equipment, as measured at the property lines, would not exceed 35dba. Since existing vegetation along the project boundary was removed, the original study had to be revised. The study shows that noise levels at points along the property line will reach 40dba. To mitigate this change from the original approval of 35dba, the applicant is proposing to install a sound wall that varies between 13 feet and 24 feet around the substation. A set of plans for the noise wall, along with photos of an established noise wall on a different project, have been submitted to the Board of Adjustment for consideration. Board members observed the noise levels on the site during the site visit and the applicant answered questions related to the noise as well.  If the Board decides that the noise level and mitigation measures are adequate, the Board should enter that information into the record and consider the next item.  If the Board decides that the noise level and mitigation measures are not adequate, the Board needs to provide specific direction to the Applicant for compliance. Staff Review Comments:  Applicant must provide a copy of the correct signed/sealed plans for the project file.  The noise wall will require construction standards plan review and building permitting.
