INTRODUCTION V3 Companies has been retained to conduct a traffic impact study for a proposed mixed use redevelopment of the west portion of Northbrook Court Mall located at 1515 Lake Cook Road in Northbrook, Illinois. Northbrook Mall is circled by a ring road that is primarily accessed by three signalized intersections on Lake Cook Road. The Mall is bounded by Lake Cook Road to the north, and residential neighborhoods to the east, south, and west. A location map is included as Figure 1. The proposed redevelopment includes the removal of the existing 280,000 square foot Macy’s department store on the west side of the Mall. The proposed redevelopment includes a 315 unit mid-rise apartment complex, a 70,250 square foot grocery store, and 39,830 square feet of restaurants. The conceptual site plan includes rerouting the Ring Road to the north of the proposed redevelopment but no changes are anticipated to the signalized intersections along Lake Cook Road. A conceptual site plan is illustrated in Figure 2. The purpose of this study is to evaluate the potential traffic impacts of the proposed mixed-use development. Traffic estimates are projected to 2024, which is five years beyond the anticipated opening date in 2019. The study area includes the western signalized intersection of Lake Cook Road and Northbrook Court Drive in addition to the Ring Road. This report includes a description of existing conditions, data collection and capacity analysis, evaluation of data, and conclusions. - 1 - REDEVELOPMENT AREA NORTHBROOK COURT FIGURE 1 REDEVELOPMENT SITE LOCATION MAP NORTHBROOK ILLINOIS GROCERY STORE APARTMENT RESTAURANT RESTAURANT NOT TO SCALE NORTHBROOK COURT FIGURE 2 REDEVELOPMENT CONCEPTUAL SITE PLAN NORTHBROOK ILLINOIS Traffic Impact Study Northbrook Court Mall Redevelopment, Northbrook, Illinois II.
