City Council Meeting Minutes August 19, 2008 Page 11 of 18 with the AH Flood Designation, the lowest habitable floor shall be elevated to elevation of 5,332. Grading: The applicant provided a preliminary grading plan to fill portions of the property to an elevation of 5,336. In order to fill to the extent with the 20-foot wide setback available from County Road, a series of three, 2' high retaining walls are shown. The Fire Marshall has requested the height differential be reduced to allow fire crews to adequately access areas behind the buildings from adjacent roadways. Staff recommended the overall grading plan be revised to limit the extent of fill to the Base Flood Elevation of 5,332. Drainage: An on-site detention pond has been proposed to accept and release all runoff at the historic rates. _Preliminary PUD Development Plan: The request is for approval of 14 townhome units and 5 single family homes on a 52,311 square foot parcel (1.2 acres). The townhome units are located on the north portion of the property adjacent to Elm Street and County Road. The townhomes will be in five separate buildings and designed to look like row houses. Building One and Five have two attached units, Building Three and Four have three attached units and Building two has four attached units. All the structures are designed to be 30 feet in height. The 5 single family homes are proposed on 5 individual lots with lot sizes ranging from 3,814 SF to 4,266 SF. Density: The property is located in the Residential Medium Density (RM) zone district, which permits multi-family development at duplex or townhouse densities. The density permitted is one unit for every 3,500 SF of lot area. The applicant is requesting approval of 19 units on the property that measures 52,311 square feet. The maximum density provided for under the RM zoning is 15 units. Staff did not support the proposed density. As a condition of approval, Staff recommended the PUD be revised to eliminate two units from the proposal. Architecture: The applicant provided a mixture of flat roofed structures and pitches. The PUD requests a 30' maximum building height rather than the required 27' building height by the Old Town Overlay. The Planning Commission felt the roof pitches should be compliant with the surrounding neighborhood homes. Access: The applicant plans to utilize the alley for primary access from the townhomes, as well as the single family homes located on Lots 1, 2, 3 and 5. The primary access for the townhomes will be from an internal driveway that obtains access from the adjacent existing alley. Lot 6 will utilize the existing driveway off of County Road for access. The internal driveway has been dedicated as a 20' access easement on the plan. The townhomes will have two- cargarages with access off the internal drive. The alley varies in width from 17.5
