Councilmember Sullivan confirmed that the noise level within a residence's bedrooms would then be roughly 64 decibels, sometimes occurring at 2 a.m., and noted that decibels increase on an exponential basis. Councilmember Cook- Kallio said she walked the property and confirmed with staff that the setbacks of the three homes in question are fairly consistent with almost all development in the immediate area. She asked how the proposed sound wall compares to that behind the existing development to the east. Mr. Otto said it is similar in height. Based on the sound attenuating windows, he guessed the proposed homes would have higher sound reduction than those currently along the railroad tracks. Councilmember Sullivan inquired as to the qualifications of the consultant who prepared the shadow study. Mr. Otto said the applicant's architect prepared the study. Councilmember Sullivan noted an architect is not a photovoltaic engineer. He said he prepares studies like this in a professional capacity and questioned its technical validity and noted that PV systems are particularly sensitive to shadow and as little as 10% of the modules situated in shadow can significantly decrease the output of the entire array. Councilmember Thorne disclosed that he met with the property owner, walked the property, and met with a representative of the PHA. He asked if any densities, other than what is proposed tonight, were considered at the Planning Commission workshop. Mr. Otto said another 14 unit plan, similar to this, was reviewed. Community Development Director Dolan said some Commissioners were interested in reducing the number of lots to accomrnodate guest parking more easily. Ultimately, the applicant was able to do so with some other redesign and the Commission seemed to be satisfied. Councilmember Thorne asked if the park off Del Valle is large enough to include play equipment, if it does not already. Mr. Dolan said it is not large enough and is constrained by an existing home that runs along side of it. The Specific Plan also calls for future improvements to accommodate parking to support the trailhead adjacent to it. Councilmember McGovern confirmed with staff that the rezoning would support a density greater than eight units per acre, and does not require the 12 units per acre currently proposed. She asked what size lot would be needed to accommodate retention and renovation of the site's existing home. Mr. Otto said the Council could approve whatever setback it wishes around the home with a PUD developrnent and the lot size could vary. Councilmember McGovern confirmed with staff that retaining the existing home would cause some change to the circulation of the proposed development. Councilmember McGovern requested more information from staff regarding the portion of the site that was dedicated to the City in 1980. Mr. Otto could not speak to the origin of the gift but said it is now, and was then, a portion of Stanley Boulevard. Councilmember McGovern confirmed with staff that the dedication would not revert to the original property owner as part of this development. She expressed concern with the lack of green and play space for children, particularly with 3- and 4- bedroom units planned for the development. Mr. Otto noted that some models do not extend to the setback line and would have a larger rear yard, though some are conversely fairly narrow. Councilmember McGovern referred to photographs of the site and asked why more foliage is not included along the railroad line to buffer sound. She noted the development to the east City Council Minutes Page 9 of 16 December 7, 2010
