addition, a sidewalk would require the removal of a substantial portion of the front yard landscaping, some of which is being used for stormwater treatment. Parking Two garage parking spaces would be provided per unit. In addition, residential driveways would be at least 18-feet long to accommodate parked vehicles in front of the garage. Five guest parking spaces would be shared by the development. Currently, general public parking is allowed on both sides of Stanley Boulevard as long as vehicles are parked off of the pavement. As part of the Stanley Boulevard reconstruction project, a paved parallel parking lane will be provided on the north side of the street with no parking allowed on the south side of Stanley Boulevard. Since there would be no on-street parking within the development, staff believes it is important to provide guest parking, and the applicant has provided five spaces. Staff believes the five guest spaces should be adequate for the project provided that the garages are not modified by the residents or used for storage in a manner that would interfere with the ability to park two cars within the garage, that residents park their vehicles in the garages, and that the driveways are free of boats, trailers, campers, etc. to provide additional parking for guests and any additional vehicles owned by the residents. A condition of approval requires that the parking restrictions be recorded as restrictive covenants that will "run with the land" and be binding on all future property owners. With this condition, staff believes that there would be adequate parking provided in the development for both residents and guests. Noise and Vibration External noise sources that could affect the site include noise from the railroad to the north and traffic on Stanley Boulevard to the south. For single-family housing projects, the City's General Plan generally requires that private yard areas excluding front yards not exceed 60 day/night average decibels (dB Lda) and that indoor noise levels not exceed 45 dB Lin. In addition, if the noise source is railroad, an exterior noise level up to 70 dB Ldn is allowed and indoor noise levels cannot exceed a maximum instantaneous noise level (L,,,ax) of 50 dB in bedrooms and 55 dB in other rooms. A noise study was prepared to ensure that the project will meet General Plan noise standards. In order to meet the General Plan noise standards, the noise study indicates the following mitigation is required: • Install an 8-ft. tall acoustically effective barrier along the rear property lines of Lots 5, 6, 7, and 9 and along the rear and eastern side property lines of Lot 8. The applicant is proposing to install an 8-ft. tall precast concrete soundwall at these locations (see the fencing exhibit, Sheet L2, for the proposed design). Staff notes that the soundwall heights on the fencing exhibit need to be modified to conform to the height requirements of the noise study. A PUD-82 Page - 14 - September 15, 2010
