City Council Regular Meeting Minutes March 9, 2021 Page 5 1 2. In this additional setback space, plant a continuous row of Spruce trees no greater than 15 2 feet on center, to create and grow a buffer between the access aisle and the adjoining 3 multi -family residential building. Due to the proposed grade and retaining wall, a wider 4 space (and thus, greater shift) may be necessary to accommodate this planting. 5 3. Add larger evergreen trees to the northwest corner of the site to moderate impacts of 6 headlights in the stacking lane. 7 4. Reorient the parking/access lanes in the front area to 90 -degree parking angles, and 8 eliminate the one-way circulation patterns that add unnecessary pavement. 9 5. Add a solid fence line along the north boundary/alley to create a buffer between the 10 commercial activity and the single-family neighborhood to the north, and add 11 landscaping in that space to enhance the visual aesthetic and reinforce the buffer. 12 6. Add larger evergreen stock in the northeast portion of the stacking lane area to screen 13 headlights from the single-family properties. 14 7. Add a permanent, noise -insulated structure to house the vacuum machinery from which 15 only vacuum hoses may extend to buffer noise, to mitigate noise impacts on the adjoining 16 multi -family building. The structure must be consistent with the materials of the principal 17 building as required by City Code. 18 8. Operate the facility in a manner that requires entry doors to close prior to wash 19 machinery engaging the vehicle, and exit doors to remain closed until dryer machinery 20 has completed its cycle. 21 9. Reduce parking lot light pole height to no more than 20 feet, and ensure full cut-off 22 hooded fixtures to reduce light spillage onto adjoining property. 23 10. Specify hooded, downcast wall lighting on the building to avoid any light -source glare. 24 11. Compliance with the requirements of the City Engineer with regard to engineering and 25 construction, including utilities, stormwater and street improvements. 26 12. Hours of operation shall be limited to between 7:00 a.m. and 7:00 p.m. or other hours of 27 operation as may be required by this or future City Council resolution. 28 29 Mayor Stille noted Justin Messner is present to address any questions from Council. 30 31 Councilmember Walker asked about condition #7 and he is concerned about the airflow noise. 32 Mt. Justin Messner responded the purpose to allow airflow is to prevent overheating of the 33 vacuum machinery. A baffle system could be used if desired. Councilmember Walker asked for 34 clarification if the sound would be reduced with the planned enclosure. Mr. Messner stated it 35 would be reduced but would not be a sound -proof box. Councilmember Walker asked what was 36 meant by additional study is needed and Mr. Messner stated if the applicant had an additional 37 method for the vacuums, those methods would need to be reviewed by Staff. 38 39 Mayor Stille stated the noise study was long and L50 would be provided with the state standard 40 being L60. Mr. Messner stated noise monitoring was done on the site from traffic and found the 41 site was L52 -L54 decibel range. Readings were taken outside another car wash which produced 42 L63 decibels. This sound information was used to project the sound at Kenzie Terrace. The 43 maximum value found was L63 at Kenzie Terrace. When the doors are shut the noise from the 44 carwash would be L36. 45
