AONAON CENTERCENTER EENTERTAINMENTNTERTAINMENT + RESTAURANTRESTAURANT DDEVELOPMENTEVELOPMENT Traffic Study Chicago, Illinois February 2017 Prepared for: The 601 W Companies, Inc. INTRODUCTION Kimley-Horn and Associates, Inc., (Kimley-Horn) was retained by The 601 W Companies, Inc to conduct a traffic study related to development of entertainment and restaurant uses at Aon Center located at 200 East Randolph Street in Chicago, Illinois. The main component of the proposed project includes an observation deck with an exterior glass elevator system combined with multiple retail/entertainment venues and restaurant space totaling 27,375 square feet. The entertainment venues and observation deck are anticipated to have a broad attraction of guests throughout the year with an estimated annual attendance of approximately 2.6 million visitors. Parking will be provided in the Millennium Park Garage, located immediately south of the site with vehicle access provided via intermediate-level Columbus Drive and sub-level Randolph Street. Pedestrian access to/from the garage is located on the south side of upper-level Randolph Street directly across the street from the Aon Center. Access for taxis, transportation network companies (TNC) (e.g., Uber, Lyft), and tour buses will be available curbside at both the upper-level street system. School and charter bus passenger loading is planned along sub-level Randolph Street. Per direction from the Chicago Department of Transportation (CDOT) and the 42nd Ward Alderman’s office, this report includes an analysis of selected intersections in an area generally bound by Lake Street on the north, Randolph Street on the south, Columbus Drive on the east, and Stetson Avenue on the west. Key intersections on the upper-level, intermediate-level, and sub-level were included in this analysis. An aerial view of the subject site and the surrounding roadway network is presented in Exhibit 1. This report documents the study methodology, summarizes data collected, presents an evaluation of the study intersections and site access/circulation, and highlights key findings and recommendations regarding transportation elements of the proposed development.

This section of the report details information on these existing conditions. Area Land Uses The subject site is located on the northwest quadrant of Columbus Drive and Randolph Street located near the Lakeshore East neighborhood of Chicago. The surrounding area is characterized by a mix of office, residential and hotel uses. Aon Center is an office building with a range of lower-level retail and restaurant uses. To the immediate south is Millennium Park with Maggie Daley Park located to the southeast. The Blue Cross Blue Shield office building is located east of the site with high-rise residential buildings further east. North of Aon Center is the Fairmont Hotel with Aqua, including the Radisson Blu hotel, on the east side of Columbus Drive. To the west is the Prudential Tower office building. Existing Roadway Network The Aon Center is bounded by Columbus Drive on the east, Stetson Avenue on the west, Lake Service Street on the north, and Randolph Street on the south. Access to the Aon Center on-site parking deck is provided via intermediate-level Lake Street, west of intermediate-level Columbus Drive. Loading access for Aon Center is provided via sub-level Randolph Street. The area roadways serving the proposed site primarily include Columbus Drive, Stetson Avenue, Lake Street, and Randolph Street. All study roadways are under CDOT jurisdiction. Additionally, a 30 MPH speed limit is assumed for all study roadways, per City Ordinance. The following section summarizes key features of each study roadway. Upper-Level Columbus Drive is a two-way, north-south roadway that runs along the east side of the site. Two travel lanes are provided in each direction with a center median through the study area. At its T-intersection with Randolph Street, Columbus Drive provides a single left-turn lane and a single-right turn lane on the southbound approach. A striped crosswalk and pedestrian signal is provided on Columbus Drive at Randolph Street. At its intersection with Lake Service Street (i.e., Aon Center drop-off/pick-up circle), a shared left-turn/through lane, a shared through/right-turn lane, a raised center median, and two receiving lanes are provided on the southbound approach. A striped area for a potential left-turn lane, a shared left-turn/through lane, a shared through/right-turn lane, a raised center median, and two receiving lanes are provided on the northbound approach. Striped crosswalks are provided on the north and south legs of the Columbus Drive/Lake Service Street intersection. Near its intersection with Randolph Street, CTA bus stops are provided on both sides of Columbus Drive including a CTA layover parking area on the east side of the street. South of the Columbus Drive/Lake Service Street intersection, a loading zone is provided on the west side of the street from 8AM to 12AM. On the east side of the street, metered parking and a food truck stand is designated. Aon Center Restaurant + Observation Deck Page 3 February 2017 North of Lake Service Street, parking is prohibited on the west side of the street; limited metered parking is provided on the east side of the street along with a taxi stand and valet loading zone for the Radisson Blu hotel. As part of an effort to improve pedestrian crossings and calm traffic, CDOT is currently considering options for reconfiguring the lanes, pavement markings, and curbside regulations along upper-level Columbus Drive north of Randolph Street. These improvements will be coordinated with the development plan, but Columbus Drive would continue to provide two travel lanes in each direction with a left- and right-turn lane at its intersection with Randolph Street; therefore, no geometric changes were included in the intersection analysis for future year conditions. Upper-Level Stetson Avenue is a two-way, north-south roadway that provides access from upper- level Wacker Drive to upper-level Randolph Street along the west side of the site. A single travel lane is provided in each direction. At its all-way stop-controlled T-intersection with Lake Street, Stetson Avenue provides a shared left-turn/through lane on the northbound approach and a shared through/right-turn lane on the southbound approach. At its minor-leg stop-controlled intersection with Randolph Street, a single right-turn lane is provided on the southbound approach. Metered parking is provided along both sides of Stetson Avenue through the study area. In addition to the metered parking, accessible parking spaces and areas for loading activity are maintained. On the west side of Stetson Avenue, two accessible parking spaces are provided south of Lake Street, and one accessible parking space is provided south of Water Street. A taxi stand is provided on the east side of the street along most the site frontage. North of Lake Street, a loading zone is provided on the west side of the street from 9AM to 4PM and 6PM to 7AM, Monday through Friday. South of Water Street, a 15-minute loading zone is provided on the east side of the street. Upper-Level Lake Street is an east-west roadway generally providing a single travel lane in each direction.

This circle drive is grade separated from Lake Street; therefore, no vehicular connectivity is provided. Pedestrian access from Lake Street and Stetson Avenue is provided to the Aon Center via a vestibule with stairs down to the building entrance. Access to Lake Service Street is also provided via an outdoor stairway. Upper-Level Randolph Street is an east-west roadway that terminates at Harbor Drive and generally provides two lanes in each direction through the study area. A marked bike lane is provided in each direction between Columbus Drive and Field Drive. Metered parking is available along the south side of the roadway between Columbus Drive and Field Drive, while parking is generally prohibited along the north side of the roadway and east of Field Drive.
