Tree number 3 of the report (English Walnut) is listed in poor health and the proposed <br />project requires its removal for the construction of the access drive. The arborist report <br />appraises the value of this tree as zero. Based on the arborist report, the tree would be <br />removed. <br />Noise Study <br />A noise study was prepared by Charles M Salter Associates, Inc. for this project due to its <br />close proximity (approximately 400 feet away) to the rail line serving both freight and <br />passenger trains (Attachment 6). The noise study was required due to the rail traffic and <br />train horn noise. The study provides comparison of the noise levels to the applicable City <br />standards and recommends mitigation measures for the project to meet the City's interior <br />Day-Night Average Sound Level (DNL) goal of 45dBA and the interior single-event <br />noise level goal of SOdBA. <br />The study indicates that the DNL can be met with no special mitigation measures being <br />required. For the single event levels to be met, the study recommends Sound <br />Transmission Class (STC) rated windows. <br />Staff's concerns with regards to noise mitigation as recommended in the noise study <br />focuses mainly on the increase of STC rating potentially requiring the use of unattractive <br />bulky windows. Interior noise levels can be mitigated by additional measures, such as <br />increased sound insulation in the walls of the structure. A condition of approval has been <br />provided to allow flexibility for construction methods to meet the noise study <br />recommendations. <br />Architecture/ Design <br />The proposed buildings are attractive and well executed with articulated forms and the <br />varied use of materials and architectural detailing that enhances the designs. Trim <br />elements include deep roof overhangs, wood post porches, and some divided light <br />windows and doors. The homes have a "four-sided" architectural design where roof <br />elements and other trim detailing wrap around the structure from the front elevation to the <br />side elevation, etc. The proposed building design compliments the design quality <br />exhibited by the existing homes, new and remodeled, facing Augustine Street. <br />The applicant intends to use brown-tones for the main color with colored accent <br />trim/detailing. <br />Proposed Streetscape <br />Item 6. a., PUD-71, Raney Page 6 of J3 Planning Commission <br />
