Councilmember McGovern confirmed with Mr. Pack that the table shows that at 75 feet, the range on Lot 6 was 89 to 112 dBA, but when it went to 57 feet it got worse, at 92 to 115 dBA. And, that the noise is louder with a smaller setback to the source's proximity. Councilmember McGovern added that a report in 2010 which said it would take a 29 foot tall sound wall along the project boundary adjacent to the railroad and flanking the sides of the project for 93 feet to actually mitigate the train engine wheel noise. Mr. Pack disagreed and said this would be needed to mitigate the horn noise primarily. Wheel rail interaction noise is better described by the first report using the L-1 value rather than the L-Max value. In using the L-1 values, mitigations proposed will reduce the train horn and train noise down to General Plan standards of 50 and 55 dBA. Councilmember Sullivan said if the Council simply disregards the train horn, the standards are met. Mr. Pack said this is what has been done in the past given the nature of a train horn. With the train horn, it cannot be functionally mitigated unless there is a 29 foot high wall. Vice Mayor Cook-Kallio asked how much the train noise is amplified if one is in a second story in that area. Mr. Pack said he was not sure what her particular window and house conditions were, but said heavy interior furnishings and carpet can reduce noise in comparison to a loft made of concrete, sheetrock and glass. Linda Garbarino, President, Pleasanton Heritage Association, voiced concern with the identified heritage neighborhoods and feels this deserves some level of protection. She opposed a tot lot, removal of trees, and demolition of the home, stating that while all homes are not charming, the neighborhood is going to be eligible for California Register status and their goal is to look at the total neighborhood which she felt should be protected. She added that the large development across from this development has trees that the CC&R's have maintained, and said practices of the City are not clearly accessible to developers and the general public and should be improved. Darrell Walterson said he thinks the old house does have intrinsic value to the neighborhood and could be restored. He voiced concerns with increased traffic on Stanley and continued concerns the shade will have on his solar panels. Emilie Cruzan distributed the petition she had emailed to the City Council with 130 signatures regarding the loss of trees and the loss of trees on the development across the street which is part of the Housing Element. She opposed the removal of trees which represent a contiguous strip of urban forest that crosses Stanley Boulevard and extend all the way to the Arroyo Del Val. The area is also a wildlife corridor and creatures move through the trees which support the riparian habitat that borders along the Arroyo in this area. According to tree reports, the Cedar trees are in good health and candidates for preservation, and once cut down and replaced with houses, there will be no room for large trees which hawks will be able to sit in. If removed and the site built out, the void of 3 acres of trees will create a heat island in the neighborhood which will generate CO2 and pollutants. She asked the Council to consider that the short term profit of an influential developer should not be at the expense of an entire neighborhood. Alan Robinette said he works next door at the window covering shop at 4225 Stanley and will be glad to see the Cedar trees removed because they are a hazard. Large branches have dropped for several years now. His PV panels will benefit from their removal and he thinks the two story homes will be a much better fit. He lives about 100 feet from the property and is also constantly trying to fight the rat population on the property. Paul Martin, applicant, said he had no rebuttal or added comments. Mayor Hosterman said the project has not been an easy one to consider. While she has opposed the cutting of trees, she also recognized they are a safety issue. She supported this type of project and its close proximity to the downtown. She recognized that the home could be City Council Minutes Page 10 of 16 September 6,2011
