(KLOA, Inc.) for the proposed residential development to be located at 640 W. Irving Park Road in Chicago, Illinois. The objectives of the traffic study are as follows: • Determine the existing vehicular, pedestrian, bicycle, and public transportation conditions in the study area to establish a base condition. • Assess the impact that the proposed development will have on transportation conditions in the area. • Determine any street, access, bicycle, and pedestrian modifications and/or improvements that will be necessary to effectively accommodate and mitigate future conditions. Vehicle, pedestrian, and bicycle counts were conducted during the weekday morning and weekday evening peak periods at the intersections of Irving Park Road with Marine Drive/Lake Shore Drive On-Ramp, Irving Park Road with Recreation Drive/Lake Shore Drive Ramps, Irving Park Road with Clarendon Avenue, Bittersweet Place with Marine and Bittersweet Place with Clarendon Avenue. Due to the ongoing COVID-19 pandemic, historic traffic counts from CDOT were reviewed including counts conducting during Cubs games. As proposed, the site (which is occupied by American Islamic College) will be renovated with an approximately 265 residential units. Additionally, the parking lot located on the north side of the building will be developed with a residential tower that will be occupied with approximately 230 senior housing units. Access to the site will be provided via the existing access drives off Marine Drive and Bittersweet Place. The Marine Drive access drive will be converted from one-way eastbound (outbound) to one-way westbound (inbound) traffic only, and the access off Bittersweet Place will be widened to allow for inbound and outbound movements. Based on the preceding analyses and recommendations, the following conclusions have been made: • Given the location of the site within an urban area and its proximity to alternative modes of transportation, the number of generated trips will be reduced. • The volume of DRAFTtraffic estimated to be generated by the proposed development will consists of less than two percent of the total traffic traversing the intersection of Irving Park Road with Marine Drive/Lake Shore Drive Southbound Ramp. • As part of the proposed development, the existing access drive on Marine Drive will be converted to inbound only access drive and the existing access drive on Bittersweet Place will be widened to allow for inbound and outbound traffic. 640 W. Irving Park Road Chicago, Illinois 1 • Ride-sharing trips for the proposed apartment building will be accommodated via the existing parking lot located in the southwest corner of the site with full access off Irving Park Road. • All truck loading will occur internally with inbound access from Marine Drive and outbound access to Bittersweet Place. Additionally, truck activity will be scheduled to occur during off-peak hours. • The turning restriction from Clarendon Avenue onto Bittersweet Place should be simplified to occur between 7:00 A.M. and 9:00 A.M. and between 4:00 P.M. and 7:00 P.M. weekdays. • To minimize southbound queues on Clarendon Avenue at Irving Park Road, consideration should be given to providing an exclusive southbound green phase. • Consideration should be given to providing a CTA transit information kiosk within the lobbies in order to further encourage public transit use. • Consideration should be given to providing on-site car sharing services • Consideration should be given to providing a shuttle bus serving the senior housing building. The provision of a shuttle will reduce the number of individual passenger vehicle trips generated by the development. DRAFT 640 W. Irving Park Road Chicago, Illinois 2 1. Introduction This report summarizes the results of a traffic impact study conducted by Kenig, Lindgren, O’Hara, Aboona, Inc. (KLOA, Inc.) for the proposed residential development located at 640 W.
