Guptil Site, 04-RS-001 April 28,2004 Page 2 APPENDIX D The front, side, and rear yard setbacksfor the C�i of Roseville for an R-3A district are 30, ] 5, and 30 feet, respectively. Based on these setbacks, the following numbers were established for the developable areas the building pad areas: Area of Developable Area Building Pad Area Develo ment s. ft. s. ft. Elmer Street Pan�ls 33 500 21 700 Gupti113�th 19 937 11 315 Gu til South 020 31,078 Based on Roseville's zoning regulations, the minimum lot area is 2,000 sq. ft, per each 1- bedroom unit and 2,800sq. ft. for Lmits v,� 2 or more bedrooms. For the purposes of this assessment, it was assumed that all units would have 2 or more bedrooms. There are two credits that can be taken which reduce the minimum lot area requirement for the development areas involved: underground parking and contiguity to a Business District. For under�round parking, it was assumed that that each unit will have at least one parking spotprovided underground, which will allow a reduction of 3 0 0 sq. ft, in minimum lot area per unit. Contiguity to a Business District will allow a reduction of 100 sq. ft in minimum lot area per unit. Therefore, the reciuced *�+n;mm lot si2e per unit is 2,�00- 300 - 100 = 2,400 sq. ft. Based on a 2,400 sq. ft. minimum lot size per unit, the ma�mum number of units for the Elmer Streetparcels is: Developablearea/min�imurr� lot area = 33,500 sq. ft./2,400 sq. ft. = 14.0 (14units) The maximum number of u�its for the Guptil site based `or�a total developable area = 19,937 sq. ft. + 44, 020 sq. ft. = 63, 957 sq ft is: Developablearealminimum lot area = 50,488sq. ftJ2,400 sq. ft.= 26.6 (26units) BUILDING CONFIGURATIONANA IMPERVIOUSAREA � I�h� maximum number of u�its determined the configuration of the buildings for each parcel. It was assumed that each unit would be 1,100sq. ft, For thc E1mer Strcct parcels, a 3-story building with a maximum of 5 u n i ts pPS floor v� proposed to house the 14 urits. It w�s found that the north portion of the Guptil parcel would allow 5 condominiums/townhomes that were 1,100 sq. ft. in size. It was assumed that these 5 u�its would each have a 2 cargarage as part of the 1,100 ft footprint. The remaining 21 imits for the Guptil site couldbe located within a 3- story building with 7 u�its per floor on the south portion of the Guptil parcel. The maximum amount of total surface area allowed in a residential district by the city of IZoseville's City Codeis 30% ofthetotalparcel size. Therefore, the�unimpervious surface area, including buildings and paved surfaces, allowed for the parcels are as follows:
