Tree number 3 of the report (English Walnut) is listed in poor health and the proposed project requires its removal for the construction of the access drive. The arborist report appraises the value of this tree as zero. Based on the arborist report, the tree would be removed. Noise Study Proposed Streetscape A noise study was prepared by Charles M Salter Associates, Inc. for this project due to its close proximity (approximately 400 feet away) to the rail line serving both freight and passenger trains (Attachment 6). The noise study was required due to 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 SOdBA. 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. Staff s concerns with regards 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. Architecture/ Design The proposed buildings are attractive and well executed with articulated forms and the varied use of materials and architectural detailing that enhances the designs. Trim elements include deep roof overhangs, wood post porches, and some divided light windows and doors. The homes have a "four-sided" architectural design where roof elements and other trim detailing wrap around the structure from the front elevation to the side elevation, etc. The proposed building design compliments the design quality exhibited by the existing homes, new and remodeled, facing Augustine Street. The applicant intends to use brown-tones for the main color with colored accent trim/detailing. _~: _~ _ _ °~~ r e.. a . _ . ~ .. S. ~,$ Rte.. i~ ~~iE rtt.. _ .. ..,. .~ ~- 'F'P ,.
