1. Draft Lighting Policy Ted Swansegar 502-564-3020 Cell: 502-330-5653

2. Lighting- General Section (TO-701-1) Most of the Lighting Guidance comes from the following References: AASHTO Roadway Lighting Design Guide “American Association of State Highway and Transportation Officials” IESNA Recommended Practice for Roadway Lighting Publication RP-8 ALL Lighting layouts for Construction should follow the recommendations in the manuals stated above!!!!!

3. Lighting- Responsibilities (TO-701-2) Changed Cabinet Responsibilities – Roundabouts (NEW) – Rest Areas and Weigh Stations (New) – The cabinet may enter into agreements with local governments or electric utility companies for any or all of these responsibilities. – Relocation of existing municipally-owned lighting for roadway projects along state-maintained roadways. Design work by Utilities or cabinet – May design and install bases, conduits, and junction boxes for future lighting by others on roadway projects. – Unwarranted lighting (excluding decorative fixtures) can be installed on a roadway project if the following: Project team supports installation Project funds are available Local officials sign an agreement to maintain(utility costs)

4. Lighting Responsibilities (TO-701-2) Responsibilities of others (the cabinet shall not be responsible for the design, installation, operation(utility costs), or maintenance of the following: – Aesthetic – Decorative – Delineation – Not listed in cabinet responsibilities Utility owned: relocation costs and design shall be responsibility of the Utility Company

5. Lighting Warrants and Approval (TO- 701-3/ TO-701-4) Warrants (these may influence the decision to approve) – roadway geometry, sight distance, crash rates, fog/ice/snow, and funding Lighting for the cabinet is approved by the Division Lighting for others is also approved by the Division with exception of delineation lighting (District Approval). Lighting by others shall go through the Encroachment Permit process and the permit shall serve as the approval of the lighting.

6. Project Development Process There are 8 steps in this process. – District Design Project Manager notifies the District/Central Office of meeting that may involve lighting – Go to Meetings (PLEASE GO TO THESE IF POSSIBLE!!!!) – Evaluation of if lighting is needed/replaced by the whole project team (make decision hopefully that is backup by comprehensive study) – If lighting recommended by Project Team, the District Traffic Engineer shall send in a written request to Central Office for approval. All data shall be submitted for this approval. If the project team wants Central Office to do the design, this shall also be requested in the written request to Central Office. – Review by Central Office and a decision will be send back the district if approved or not. – Project Manager/consultant notifies Design Services Branch as soon as possible for located poles/bases if there may be problems with utilities/right- a-way. – Completion of plans (district review if possible) – Final plans for Construction Letting!!!!!

7. Lighting- Plan Development (TO-701-5) Please Read!!!!!! We do not install decorative lighting

8. Lighting- Inspections (TO-701-6) Design Services will inspect all lighting on construction and permit projects. Inspections/letters will be completed within 90 days of notification!!!

9. Lighting- Permitted Installations (TO- 701-7) All lighting done by others All lighting shall be designed by Prequalified Consultant. All lighting submittal shall include Permitted Lighting Submittal Checklist (Exhibit 26). Typical Submittals may include the following: – Pole base design, poles (breakaway), luminaires, arms, banner/flag brackets, electrical disconnects All lighting shall be installed by Prequalified Contractor (except for utility installations). Central Office will inspect all permits that involve Lighting.

10. Lighting- Interchange Lighting (T0-702) New warrant for Partial Interchange Lighting – Average Daily Mainline (Urban- 25,000 rural- 10,000) – Average Daily crossroads- 1,000 Design Layout for Partial Interchange includes: – Within limits of the intersection with ramps and crossroads. – If intersections are less then 1000 feet, there shall be continuous lighting between the intersections. – May include end of lane taper where the on-ramp and mainline merge.

11. Lighting- Intersection (TO-703) Coverage Area: – Full Intersection (Signalized)- Both approach and limits of intersection. – Partial Intersection (Unsignalized)- limits of the intersection. – If two lighted intersection is less than 1000 feet, continuous lighting is warranted. Illuminance Levels (NEW) : – Limits of intersection- includes area within all stop bars in the intersection. – Average maintained illuminance (AMI) for both mainline and crossroad (limits of intersection will be greater of the two and then multiply by a factor of 1.3 to get AMI). – Approach lighting- AMI for each approach – Approach should be about 400 feet in advance of the limits of the intersection. – Approach lighting is only for roadway that is approaching the limits of the intersection.

12. Lighting- Delineation (TO-704) Only through a encroachment permit!!! Shall not be installed on Existing Traffic Signal Poles. Design: – Existing Utility poles in clear zone – Breakaway supports within the clear zone – Supports outside of the clear zone – Luminaire should be mounted at least five feet from the shoulder of the mainline approach, intersection radius, and side street approach. – Luminaire should be mounted no further 15 feet from the shoulder of the mainline/approach. – luminaire wattage shall be 200/250 and be mounted a minimum of 35 feet above the roadway. – Luminaire shall be mounted either parallel to the mainline or diagonal to the intersection.

13. Lighting- Roundabout (TO-705) All roundabouts shall have lighting!!!! Coverage area- full intersection lighting Illuminance levels: – Same as full intersection lighting – Limits of the roundabout is defined as the area encompassed by the circular roadway within the yield lines on each approach.

14. Lighting- Bridge (TO-707) Minimize Vibration- minimize arm lengths and incorporate a dampening device. All poles of bridges shall have a grounding system installed.

15. Lighting- tunnel (TO-707) Warrants – Nighttime- If luminaires positioned adjacent to tunnel cannot provide adequate lighting. – Daytime- if user visibility requirements are not satisfied by the sunlight.

16. Lighting- Underpass (TO-707) Warrants: – Frequent nighttime pedestrian traffic – Unusual or critical roadway geometry

17. Lighting- Navigation/Aviation (TO- 708/709) Maintenance- conduct periodic inspections and keep records of inspections in KEPT. Example navigation inspections: exhibit 27

18. Lighting- Weigh Station/Rest Area Is warranted and should be maintained by the District.
