However, the City has reviewed applieations for this <br />site in the past \^ith similar proposed uses where a reduction of the total number of <br />required parking was approved by Council. For example, starting in April 2003 tlic City <br />reviewed an application for 39,000 s.f. of office condos for this site. After consulting <br />with the City tingincer and the City’s planning consultant a parking requirement of 3 5 <br />stalls per 1,000 s.f. using 85% of the gross floor area was accepted by Council. The <br />applicants for this proposal were advised to use that calculation and have met the parking <br />standard (34,186 s.f. / 1000 x .85 = 101.70 stalls). The proposed number of stalls shown <br />on the plan is 103. <br />Surface Water Management Plan <br />All roof and parking lot runoff will be collected via catch basins and transported via <br />underground storm sewers to the existing storm sewer system serving the Orono Woods <br />senior housing site, discharging to the existing NURP pond located at the northwest <br />comer of Brown Road North and existing Highway 12. <br />Capacity and design of the pond were previously deemed acceptable by MnDOT, the <br />Minnehaha Creek Watershed District and the City for development of this site for office <br />use under the PUD No. 2 approvals. The City Eingincer has requested that u drainage <br />area map and stonn sewer calculations be provided by the applicants, as well as evidence <br />that the downstream storm sewer has the capacity to serve the projioscd use. At least one <br />additional catch basin is requested by the City Engineer to contain runoff from within the <br />site. Additional engineering comments are listed in the City Engineer’s memo dated <br />January 11, 2005 and attached to this report as Exhibit O. <br />1'opography Impacts <br />Lot 1 is significantly higher than the adjacent parcels on cither side, with its high point <br />near the northeast comer. The land slopes to the northeast, southeast and southwest from <br />this point. Existing grade level rises 28’ from the southeast comer of Lot 1 to the high <br />point at the rear. The grade elevation of the existing home in Sugar Woods directly <br />behind Lot 1 is at or slightly above the highest elevation on I.ot 1. <br />The west and northeast clusters will walk out on the north side. Proposed walkout floor <br />elevation for the west and northeast Clusters is 1009’^ or about 15 ’ below the high point <br />of the hill, requiring significant excavation of an ea.st-west ditch parallel with the rear lot <br />line, supported by a retaining wall system. First story lloor elevations for these two <br />clusters will be as much as 5 ’ below the crest of the hill in some locations along the rear <br />of the property, helping to lower their visual impact as viewed from the north. Due to the <br />northeasterly slope, the northeast facade of the northeast cluster will be fairly visible from <br />the northeast, although some bemiing is also proposed in the northeast corner of the site <br />as screening. <br />Both no 'hcast and southeast clusters will expose their entire easterly facades to the <br />Senior Housing site to the east. This will be accomplished by .some fairly deep cuts into <br />the east facing sideslope along the east lot line. A low berm will be left along the cast lot <br />line that will provide minimal screening of the lower facatles as viewed from the east.
