Higgins Road, Suite 00 DATE STUDY PERFORMED: /17/2017 Rosemont, Illinois 001 CBBEL PROJECT NO.: NARRATIVE: LENGTH: APPROXIMATELY 1075' ROADWAY CLASSIFICATION: MAJOR PEDESTRIAN ACTIVITY: MEDIUM TRAFFIC CONTROL: 4-WAY SIGNALIZED INTERSECTION AT RIDGE AVENUE AND LAKE STREET 2-WAY STOP AT RIDGE AVENUE AND GREENWOOD STREET 4-WAY SIGNALIZED INTERSECTION AT RIDGE AVENUE AND DEMPSTER STREET TYPE OF LIGHTS: TALLMADGE HEIGHT: 1' WATTAGE: 5W LAMP: INDUCTION LOCATION OF LIMITS: MID BLOCK RESIDENTIAL NUMBER OF LIGHTS: 20 CANOPY DENSITY: HEAVY LIGHTING STUDY AREA 4A SUMMARY THE AREA STUDIED RUNS ALONG RIDGE AVENUE AND SPANS ABOUT 1075 FEET. THE AREA WAS SELECTED DUE TO BEING IN THE HISTORIC DISTRICT. LOCATION: RIDGE AVENUE FROM LAKE STREET TO DEMPSTER STREET NUMBER OF TREES: WEST SIDE RIDGE AVENUE TO GREENWOOD STREET: EAST SIDE RIDGE AVENUE TO GREENWOOD STREET: WEST SIDE GREENWOOD STREET TO DEMPSTER STREET: EAST SIDE GREENWOOD STREET TO DEMPSTER STREET: WIDTH OF STREET (FT): 3 WIDTH OF EAST SIDEWALK (FT): 5 WIDTH OF WEST SIDEWALK (FT): 5 WIDTH OF PARKWAY EAST (FT): 14 WIDTH OF PARKWAY WEST (FT): 14 SUBJECTIVE ASSESMENT: TALLMADGE LIGHT POLES EXIST IN A STAGGERED CONFIGURATION WITH LARGE POLE SPACING WITHIN THE STUDY AREA LIMITS. DUE TO LARGE POLE SPACING, EXTENSIVE TREE CANOPIES AND MINIMAL AMBIENT LIGHTING WITHIN STUDY AREA LIMITS, EXISTING LIGHTING LEVELS DO NOT MEET THE CORRESPONDING LIGHTING STANDARDS ASSOCIATED WITH THE STUDY AREA. 1

4 STREET LIGHTING MASTER PLAN EXISTING CONDITIONS STUDY AREA 4A Location: Ridge Avenue from Dempster Street north to Lake Street Area Justification: Historic District Figure 1: Tallmadge light poles exist in a staggered configuration with large pole spacing within the study area limits. Due to extensive tree canopies within study area limits, large pole spacing and minimal ambient lighting, the street and sidewalks are poorly illuminated. CHRISTOPHER B.

5 Figure 2 Ridge Avenue and Greenwood Street Intersection: Four-way stop-sign controlled intersection. Tallmadge light poles are located on the northeast and northwest corners that provide minimal illuminance to the intersection. The typical Tallmadge light pole provides excessive horizontal light, in the form of a glare. CHRISTOPHER B.

6 Figure 3 Ridge Avenue and Lake Street Intersection: Four-way traffic-signal controlled intersection. Tallmadge light poles are located on the southeast and northwest corners that provide minimal illuminance to the intersection. The typical Tallmadge light pole provides excessive horizontal light, in the form of a glare. CHRISTOPHER B.
