Per City Code Section 154.170, required parking for the proposed redevelopment consists of 748 spaces for the residential portion of the redevelopment (2 spaces/unit per City minimum requirements) and 378 spaces for the retail portion of the redevelopment (6 spaces per 1,000 sq ft). The 50 school parking spaces will also be replaced. It is likely that 350-400 of the residential parking spaces will be constructed underground in lower level parking below buildings. Based on the parking requirements, a total of 1,176 spaces would be constructed, which adds 1,076 new spaces over existing conditions. It should be noted that in the M-l Mixed Use zoning district, within which the project site is located, City Code allows the City Council to modify the minimum parking requirements as part of the site plan approval process. Traffic The proposed redevelopment project will increase the traffic volumes on roadways within the City. A traffic impact analysis of the proposed redevelopment scenario has been conducted in order to identify whether roadway and/or other transportation improvements will need to be undertaken. The analysis attempts to identify the traffic related impacts of the redevelopment project. Identified impacts are then evaluated to determine what mitigation efforts need to be enacted so that transportation service can be provided at an acceptable level. The roadways and intersections analyzed in the study were determined in conjunction with City of Centerville staff. The following intersections were examined as a part of this review: · Main Street & 20th Avenue · Main Street & Dupre Road · Main Street & Progress Road · Main Street & Centerville Road · Centerville Road & Sorel Street · Centerville Road & Heritage Street These intersections were analyzed for traffic volumes and approach geometry, both existing and proposed. The traffic analysis concluded that the proposed development will add vehicular trips to the roadway. It is currently planned to upgrade the Main Street corridor beginning in September 2007 and completing in July 2009. The system was analyzed for the year 2012, which accounted for both completion of the proposed development, and the improvements to the Main Street corridor. Based on that analysis, it was determined that the improvements being made to the Main Street corridor will adequately accommodate the expected increase in traffic volumes due to the proposed development for 2012 volumes. The roadway network was analyzed again to reflect 20 years of growth in the area to year 2030. The traffic volumes were increased by the current county state-aid growth factor, as presented by MnDOT. The analysis determined that the planned improvements to the Main Street corridor will provide overall satisfactory LOS results. Some individual movements at two intersections are expected to operate at LOS E or F. Centerville Downtown Redevelopment Page 27
