address cost analysis for restoration versus new construction in order to maintain the historical ties of the existing structure. Commissioner Narum noted that she had read the staff report and that with respect to noise, her interpretation was that all of the items listed needed to be done in order to achieve the required decibel ratings the General Plan specifies. She requested clarification regarding whether the City is doing what it needs to in order for noise to be within the required guidelines. Chair Blank noted that he had a difficult time finding the noise conditions, and Commissioner Narum identified it as Condition No. 21. Chair Blank noted that the condition did not appear to be the standard condition of approval that is used and would like it changed to reflect that. Ms. Decker stated that noise analyses generally have recommendations as described. She added that windows need an STC rate upwards of 40+ ratings, which would result in a very wide-framed window which is unattractive and does not meet the City's design guidelines. She explained that noise mitigation can also be attained through other methods such as wall construction, increased insulation, sound attenuation, etc. She noted that the noise study is part of Exhibit A under Condition No. 1. She added that staff wanted flexibility so as not to have huge, wide windows that prohibit recessed window entries. Commissioner Narum inquired how staff would know which combination will achieve the decibel level if it is different than what is being recommended. Chair Blank inquired why a noise study would be needed if its recommendations would not necessarily be followed. Ms. Decker replied that staff refers back to the noise consultant and verifies conditions to satisfy the requirement. Chair Blank inquired if the condition of approval could be subject to the recommendations of the noise consultant. Ms. Decker recommended that the condition be based on staff's consultation with the noise analyst and subject to the review and approval of the Director of Planning and Community Development. Chair Blank acknowledged the Director's expertise but felt that the condition of approval should include the noise analyst's approval. Commissioner Narum indicated that she would like the noise consultant to review the condition and provide comments. Chair Blank noted that this was all right as long as it can be met. Ms. Decker noted that noise analysts look at the project in a linear manner and do not consider other construction methodologies that can acquire the same result. She added that they do not consider increased and noise attenuation materials, such as, for example, the larger windows and unattractive elevations PLANNING COMMISSION MINUTES, July 23, 2008 Page 6 of 25
