The applicant has provided additional information on parking supply at comparative projects to <br />support the proposed parking design. <br />2. Underground Parking. The code requires, subject to any variance waiver, that most of the on- <br />site parking is provided underground. The applicant is limited to just 16 surface spaces in part <br />because impervious surface standards on this small parcel limit further pavement for parking or <br />other purposes, even with a variance of about 10% over the standard. If the building were <br />elevated to provide an under-building parking story, both parking supply and impervious <br />coverage would be less of an issue. <br />Factors for variance in this case are essentially an appeal to the smaller number of parking spaces <br />necessary for assisted living housing compared to other multi-family and senior housing generally. The <br />applicant is reluctant to consider underground parking, and absorbing the cost for what is most likely to <br />be an effective over-supply of parking on the site. This factor is a balance between economics and <br />reasonable use for the site – while economics are not to be used as the sole rationale for a variance, <br />they can play a role. The applicant’s variance appeal here is based largely on the factor that the parking <br />supply provided in an under-building parking garage would go largely unused – an economic burden that <br />provides no specific benefit to the land use. <br />Staff believes that there may be reasonable grounds for variance consideration in this case, given that <br />the purpose of the underground (or under-building) parking is to limit surface parking and the <br />impervious surface that comes with it. In this case, there would still be a need for some surface parking <br />for visitors and transient employees, even if there were underground spaces available. In this way, the <br />underground requirement can be viewed as an unreasonable burden on the otherwise reasonable use <br />of the property. <br />Moreover, staff has undertaken additional research on parking demand for assisted living facilities. A <br />common standard is .25 spaces per bed, plus .5 spaces per employee. For this facility, with 38 maximum <br />beds and 5 staff, the estimated parking demand would be 12 spaces. As such, staff believes that the 16- <br />space parking supply would be sufficient for nearly all conditions, with an occasional exception for a few <br />high-demand events such as Mother’s Day. <br />Building Design and Materials <br />The proposed building is designed as a two-story facility with a gabled roof and two cross-gables along <br />the north (front) wall. The south exposure does not show any additional architecture variation either in <br />the roof or wall plane. The R-4 District includes the following requirement: <br />The applicant for any multi-family structure in the R-4 District shall provide a proposed materials <br />palette, including a plan that shows brick, stone, glass, and architectural metal on no less than <br />50% of all building walls. Architecture shall include significant articulation in both wall facades <br />and building roofline. <br />The building materials for this structure are primarily lapped metal siding and a wainscot of simulated <br />stone, as well as other stone elements around the main entry facing the parking area and toward the <br />street. The west (street), north, and east exposures show some changes in building wall and roofline. <br />However, the south wall, adjoining the apartment property and subject to the requested setback <br />variance, shows little articulation as noted above. Staff would recommend that this exposure is <br />addressed to add visual interest on this side of the building. This recommendation is strengthened by <br />the fact that this exposure is limited in potential landscape planting due to underground utilities and the <br />narrowed side yard. Enhancing the visual impact of this exposure would help offset the lack of landscape <br />and the setback reduction. <br />As noted, the applicant has added cross gables to the south roof plane, and enhanced the <br />materials on the south and west side of the building with additional stone wainscot. <br />26
