zero. Based on the arborist report, the tree would be removed. Various trees are proposed to be installed throughout the project. Given the close proximity of the project site to the Union Pacific Railroad (approximately 400 feet away), a noise study was prepared by Charles M Salter Associates, Inc. for this project (Attachment 6 of the Planning Commission staff report). The noise study analyzed the rail traffic and train horn noise. The study provides comparison of the noise levels to the applicable City standards and recommends mitigation measures for the project to meet the City's interior Day-Night Average Sound Level (DNL) goal of 45dBA and the interior single-event noise level goal of 50dBA. The study indicates that the DNL can be met with no special mitigation measures being required. For the single-event levels to be met, the study recommends Sound Transmission Class (STC) rated windows. Staffs concerns with regard to noise mitigation as recommended in the noise study focuses mainly on the increase of STC rating potentially requiring the use of unattractive bulky windows. Interior noise levels can be mitigated by additional measures, such as increased sound insulation in the walls of the structure. A condition of approval has been provided to allow flexibility for construction methods to meet the noise study recommendations. Please refer to the Planning Commission staff report dated July 23, 2008 for a detailed description of this project and background information (Attachment 4-B). Planning Commission The proposed project was reviewed by the Planning Commission on July 23, 2008. By a 5 to 0 vote, the Planning Commission recommended approval of the project, subject to the conditions shown in Attachment 2. The Planning Commission meeting minutes are attached for the Council's information (Attachment 5). The Planning Commission concluded that the project was well designed and the proposed density was appropriate for this neighborhood. Minor concerns were voiced over the carport designs, but the Commission concluded that the carport design was supportable with modified conditions of approval to restrict storage in the carports and to require future modifications of the carports be processed as Planned Unit Modifications. The Planning Commission discussed the removal of the Pecan tree and modified the conditions of approval to require payment into the Urban Forestry Fund in the amount of half of this tree's appraised value. A discussion on the historic homes (Lots 1 and 5) focused on the handling of future additions and/or new construction requests. This discussion resulted in a condition of approval requiring any additions and/or new construction on these lots to have a copy of the plans provided to the Planning Commission during the noticing process.
