Higgins Road, Suite 00 DATE STUDY PERFORMED: 8/24/2017 Rosemont, Illinois 0018 CBBEL PROJECT NO.: 170054 LIGHTING STUDY AREA 2A-9B SUMMARY THE AREA STUDIED RUNS ALONG DODGE AVENUE AND SPANS ABOUT 1350 FEET. THE AREA WAS NARRATIVE: SELECTED DUE TO HAVING A BIKE LANE AND UNCONTROLLED CROSSINGS. LOCATION: DODGE AVENUE FROM WASHINGTON STREET TO SEWARD STREET LENGTH: APPROXIMATELY 1350' ROADWAY CLASSIFICATION: MAJOR PEDESTRIAN ACTIVITY: MEDIUM TRAFFIC CONTROL: 1-WAY STOP AT DODGE AVENUE AND WASHINGTON STREET 1-WAY STOP AT DODGE AVENUE AND MADISON STREET UNCONTROLLED INTERSECTION AT DODGE AVENUE AND MONROE STREET 1-WAY STOP AT DODGE AVENUE AND CLEVELAND STREET CONTROLLED INTERSECTION AT DODGE AVENUE AND SEWARD STREET TYPE OF LIGHTS: TALLMADGE HEIGHT: 1' WATTAGE: 85W LAMP: INDUCTION COBRA HEAD INDUCTION HEIGHT: 25'-30' WATTAGE: 200W LOCATION OF LIMITS: MID BLOCK RESIDENTIAL NUMBER OF LIGHTS: 13 CANOPY DENSITY: HEAVY NUMBER OF TREES: WEST SIDE WASHINGTON STREET TO MADISION STREET EAST SIDE WASHINGTON STREET TO MADISON STREET WEST SIDE MADISON STREET TO MONROE STREET EAST SIDE MADISON STREET TO MONROE STREET WEST SIDE MONROE STREET TO CLEVELAND STREET EAST SIDE MONROE STREET TO CLEVELAND STREET WEST SIDE CLEVELAND STREET TO SEWARD STREET EAST SIDE CLEVELAND STREET TO SEWARD STREET 3 4 7 4 3 4 4 WIDTH OF STREET (FT): 50 WIDTH OF EAST SIDEWALK (FT): 10 WIDTH OF WEST SIDEWALK (FT): 5 WIDTH OF PARKWAY EAST (FT): 5 WIDTH OF PARKWAY WEST (FT): 10 SUBJECTIVE ASSESMENT: COBRA HEAD-TYPE METAL HALIDE LIGHT POLES EXIST IN A STAGGERED CONFIGURATION WITH LARGE POLE SPACING AND EXTENSIVE TREE CANOPIES WITHIN THE STUDY AREA LIMITS. DUE TO LARGE POLE SPACING AND EXTENSIVE CANOPY COVERAGE WITHIN STUDY AREA LIMITS, EXISTING LIGHTING LEVELS DO NOT MEET THE CORRESPONDING LIGHTING STANDARDS ASSOCIATED WITH THE STUDY AREA. 1

Figure 2: Cobra head-style induction davit arm light poles exist in a staggered configuration along Dodge Avenue within study area limits. CHRISTOPHER B. BURKE ENGINEERING, LTD. 9575 W Higgins Road, Suite 00 Rosemont, Illinois 0018-4920 Telephone (847) 823-0500 Fax (847) 823-0520 5
Figure 3: Due to extensive tree canopies within study area limits, large pole spacing and minimal ambient lighting, Dodge Avenue, bike lanes, sidewalks and parking stalls are poorly illuminated. A single Tallmadge light pole exists at each intersection within the study area limits. The typical Tallmadge light pole provides excessive horizontal light, in the form of a glare. CHRISTOPHER B.
