August 20, 2019 Page 9 In this regard, there is reliable research from the Institute of Transportation Engineers (ITE) in its “Parking Generation” manual as to the number of parking spaces required for suburban multiple family buildings with access to transit. There is extensive transit coverage in the Silver Lake Village area, and Metro Transit is currently working on enhancing its transit stop capacity along Silver Lake Road. For such developments, a parking requirement equal to one parking space per .9 bedrooms can predict actual parking demand. The total number of bedrooms in the 464 unit project is 602, based on the projected unit mix (described below). The proposed 813 parking spaces results in a ratio of 1.35 spaces per bedroom, which should be more than enough to serve the project. The ITE manual also projects parking demand by unit count, with a peak accumulation for projects of this type at about 1.4 spaces per unit. This would result in a demand of approximately 650 parking spaces. As noted previously, the Planning Commission included a consideration that parking be further examined to entertain the possibility that the total parking coverage could be lessened, thereby increasing green space on the site. In reviewing this option, it appears that total parking demand may turn out to be somewhat less than the proposed supply. However, this is based on the average of a variety of other studies which have a wide variation in actual demand. While the parking supply may be greater than eventual demand for this project, it is speculative to reduce the proposed parking availability. Staff does not recommend reducing the supply below that proposed, which is already a reduction from code requirements. As noted below, the green space on the site will be increased over the current condition, even with the parking supply as proposed. Dimensional Requirements. According to the Ordinance, off-street parking spaces must measure not less that 9 feet in width and 19 feet in depth. While all surface parking stalls are shown to appropriately measure 9 feet in width, stall depths of 18 feet are proposed. This dimension is generally considered functional, but will require attention from the management during winter season due to snow plowing and accumulation. If possible given site dimensions, 19 foot depth parking stalls would be a better design. Disabled Parking. According to the American Disability Act, required accessible spaces (for persons with disabilities) varies by the number of spaces in a parking lot. For parking lots which provide 501 to 1,000 spaces, two percent of the spaces must be devoted to use by disabled persons. For 813 parking spaces for example, a minimum of 17 disabled spaces are required. The parking plan for the parking garage has not, to date been provided. Thus, it is not possible to identify the total number of disabled parking stalls which are to be provided. The submitted site plan illustrates 340 surface parking stalls and 10 disabled stalls which is considered adequate. 43
