Planning Commission Meeting, June 20, 2023 Page 4 Legends multi-family residential building, then turning into the wash building away from residential structure. Exiting traffic faces the institutional building and parking area. No changes are planned for this pattern. Item 3 relates to mechanical wash equipment standards. The mechanical wash equipment is an existing condition of the facility, and is not proposed to change. Finally, Item 4 requires that vacuum equipment be housed with the primary structure or is situated and designed to avoid noise detection at the boundary of adjoining residential property. Two residential uses adjoin this site, both multi-family structures to the east, and then to the south across 38th Street NE. The proposed vacuum equipment is shown located on a parking lot island nearer to the Legends building than the current individual vacuum units. In addition, it is unscreened from view both to the south and to the east. The applicant has provided a specification sheet that indicates the vacuum equipment will produce up to 76 decibels from a distance of 15 feet. The equipment location is proposed to be approximately 50 feet from the easterly property line, and approximately 125 feet to the property line across 38th Street to the south. As noted above, the equipment is visible from both directions. No additional information indicates the reduced noise volumes beyond the 15 foot distance. To address this, staff would suggest that enclosing the equipment within a solid screening structure should be adequate to minimize both noise and visual impacts of the equipment. The enclosure should reflect the modest materials used in the principal building, primarily colored concrete block. Such structure should successfully moderate any noise impacts of the equipment, and would effectively block views from the adjoining property. It is expected that the structure could be three-sided rather than four, leaving the side open which faces the existing building for access and maintenance of the equipment. It may also be possible to relocate the equipment and structure toward the southwesterly corner of the building, rather than the southeast corner as proposed – this would maximize its distance from the residential buildings. Parking. The proposed location for the vacuum stations occupy the currently available parking spaces on the site. Given the dimensions of the other paved spaces, parking in other locations is likely to interfere with circulation or cause other issues. There may be potential for a small number of parking spaces where the current vacuums are located, and near the proposed equipment location on the plan. These areas should be designed and striped for staff or other parking, separate from the vacuum spaces proposed. Only spaces to accommodate staff or Lighting. A final note relates to lighting of the vacuum stations. The design of similar structures includes a stream of LED lighting along the overhanging structure. The applicant should detail the lighting of the site, and show how the lighting will not impact views of the structures from the adjoining streets. The City Code’s nuisances section provides that lighting may produce no more than .5 footcandles of light at the property line adjoining a residential use, or 1.0 footcandles at other boundaries (such as the adjoining streets in this case). The applicant should demonstrate that this standard is met with the proposed lighting design.
