September 18, 2016 North Peoria Lighting Study
Purpose
The purpose of the study is to examine the requirements and practical issues involved with installing street lighting along the designated roadway. The report will cover the basic type of lighting to be provided, proposed lighting levels and installation requirements. It will also provide backup data for calculations, and a construction estimate.
Lighting Technology The most current technology for street lighting is the use of LED lights for the light source. LED lights are electronic in nature, use less electricity than regular light bulbs and are rapidly replacing any other light for street lighting purposes. Advances in technology have greatly reduced failure rates among LED lights and their costs is now coming in line with other technologies. We are currently working with a number of lighting suppliers for potential fixtures and poles. We propose to select a part from a local distributor of a national brand and design around that product. We will identify at least 3 vendors that can provide the same fixture in terms of performance and appearance. The preliminary lighting study is based on light fixtures provided by Holophane Lighting. They are an established lighting company that has experience in LED lighting for streets and highways. This report contains cut sheets that show the proposed poles and fixtures. There are other vendors that make similar poles and fixtures.
Lighting Standards The street in question is a relatively high volume expressway, with limited access. There are no houses or business that exit directly to this stretch of Peoria. According to the NHTSA, the minimum lighting level for this type of roadway would between .6 and .9 foot candles. The foot candle is a standard measure of lighting intensity. Computer projections allow the modeling of a lighting system to project the amount of light intensity the design will provide. This is done with a projected “foot candle map”. Using computer modeling, for a projected area, the foot candle level of a lighting design can be calculated, along with other variables such as max/min ratio. These are the parameters to be examined when determining if a roadway has an adequate design. This report contains a foot candle distribution report. The following page contains a table with variables needed for defining street for the selection of lighting fixtures and determination of the proper number of fixtures. The variables include the type of paving used and street criteria based upon traffic volume and pedestrian traffic. The road type is class R2. The street classification is for a Major roadway with medium pedestrian conflict for the South end near Pine and South of Virgin. For this type of roadway, the average foot candle level is .9 FC. For the North section of the road in question, the road way is still a Major roadway, but the pedestrian conflict is medium to low. For this type of roadway the minimum foot candle average is .6 FC. The other factors are the Average/Minimum ration which is the highest light level divided by the lowest light level and the Max/Min, which is the maximum light level divided by the minimum light level. The final design will meet these lighting levels and design limits, as required for a good lighting design. We will have language in the contract that will hold the contractor responsible for meeting the designed lighting levels. The equipment selected will be guaranteed to perform to the level shown in the design, or the vendor will be required to make adjustments to the equipment at their expense until the parameters are met.

Wiring for Light Poles In keeping with city standards, we propose to feed the lighting with underground conduit and wire. A conduit is a plastic or metal pipe used to protect buried or exposed wire. Where needed, the road can be bored to connect circuits across streets. There are already in place, two lighting controllers that were used for Christmas tree lighting on Peoria. These controllers contain timers and photocells and are located on the East side of Peoria. It will be possible to re-use these controllers to power the street lights. I will be meeting with Terry Ball, director of traffic engineering to confirm this. We will also attempt to put in place any anti-theft measures the City of Tulsa is now doing, to help prevent the theft of wire used for lighting. It is possible that these lights might also use aluminum wire.
Site Conditions The roadway in question is existing and has no current work ongoing. The road was completely re-built in 2002. For the most part, the road is 4 lane (2 north bound and 2 south bound lanes). Parts of the road are divided by a median, that has planters and trees installed. Of the total length of 1.1 miles, approximately .3 miles of it has a median that could have light poles installed in them. The is no lighting over most of the road in question. On the South end of the project, at Pine, on the West side of the road, there are several large PSO owned high voltage poles with lights attached. Because of their distance from the roadway, they put very little light on the street. On the East side of the street, for the total length of the project, there is a biking/jogging trail. The trail varies in distance from the road, from being right at the roadway, to being 20’ to the East of the road. There is a series of light poles in place for the trail, but none of the lights are working. It has been reported for several years the trail lights were not functioning, and the City of Tulsa has reported that the wiring for the lights has been damaged by vandals. It was asked if the street lights could also cover the biking/jogging trail, but because of the meandering nature of the trail and the distance it is from the street, this would not be possible. The trial lighting would need to be addressed by repairing the existing lights under a separate contract. The site conditions vary from one location to the next, and the study will cover how we propose to light each area. I will examine the areas going from the South end of the project at Pine to the North end at Apache.
PRELIMINARY LIGHTING PLAN The preliminary lighting plans shown in this report contain our preliminary lighting layout. It shows a total of 41 poles. Of these poles, 30 are 30’ tall aluminum poles with a single 10,000 lumen LED fixture, at the road edge. The other 11 poles are twin light poles, 30’ tall, with two 10,000 lumen LED 180 degrees apart. The twin light poles will be mounted in the median. The preliminary design has several areas that may need to be adjusted and because of some low light areas, I have assumed another 4 poles will eventually be added over the length of the project, so for the purpose of the estimate, I have shown 34 single light poles and 11 twin light poles. I will need to get approval from the City of Tulsa to install lights in the medians. Currently the medians have trees installed in them. I propose to minimize or eliminate the need to remove any mature trees when installing the lights. If we are not able to use the medians, we can install the lights on the East and West sides of the road, but the pole count will increase by around 5 poles. PROPOSED POLE AND FIXTURE The pole/fixture combination we propose to use as our design basis is the Holophane Esplande Tear Drop fixtures. The LED lights are on the “yellow” end of the light spectrum at 3000K. The fixtures are mounted on 30’ tall, 5” D round steel poles. The poles are to be mounted on a standard 18” diameter concrete base. Wiring shall be underground in 1 1/2” PVC conduit buried 30” below grade. The pole and fixtures are shown in the attached cut sheets.
