Planning Commission Staff Report January 12, 2012 Maximum Lot Coverage:85% Minimum Front Yard Setback (Principal Uses):6’ (all conditions) Minimum Side Yard Setback (Principal Uses):5’ (all conditions) Minimum Rear Yard Setback (Principal Uses):4’ (to alley) Setback from collector street ROW:parking: 15’; building: 10’ Setback from local street ROW:parking: 5’; building: 5’ Minimum building separation:10’ Maximum Building height:55’ (principal); 35’ (accessory) The multi-family units consist of 10 multiplex apartment buildings clustered around a common open space. The open space area will provide pedestrian connections leading to the adjacent trails and a clubhouse/pool. Height The preliminary PUD proposes the buildings be built to heights previously approved by the GDP:Single-family structures will be permitted up to 35’ in height and all Multi-family structures will be permitted up to 55’ in height. When staff reviews a height request we use an exercise known as a “shadow analysis”.This isa modeling exercise to show where potential shadows will be casted at all times of the yearandis used to show if there are any detrimental effects of the proposed buildings on existing structures. In the case of Steel Ranch South, all proposed new development is north of the nearest development, Christopher Village. Therefore shadows will not be a detriment on the surrounding structures and “shadow casting” is not required. Parking Typical site layouts of Planning Area 4A reflectthat each unit will meet the required off- street parking requirement of two spaces per unit.On street parking is also being provided for quests.Each unit being proposed is an alley loaded model, therefore there will be nofront garage loaded units. Phasing Plan Aprovided phasing plan in the PUD reflects Planning Area 4B, the multi-family development, will be built first, with the intent to start construction in early summer. Transportation The primary access for this development is from Hecla Drive and ultimately Hwy 42. Secondary access is proposed from South Boulder Road. South Boulder Road access would primarily be for right-in only and emergency egress for the following reasons: a.Property frontage along South Boulder Road-Due to the limited width of the property frontage along South Boulder Road (approximately 200 feet) there isn’t enough separation between the existing access at Christopher Village and the BNSF Right of Way for a new access. b.BNSF & South Boulder Road median-The existence of the median along South Boulder Road prohibits anything but a right-out movement.
