GENERAL DESIGN CONSIDERATIONS
5.02.1
Illumination
5.02.1.A " General
As part of the public improvement process, a street illumination design shall be included with all
project plans submitted to the City as well as a power plan from the Springfield Utility Board. The
street illumination design shall clearly show where the luminaires, conduit runs, junction boxes,
service cabinets, and power sources will be located. Each lighting component shall be identified
using the Oregon Department of Transportation drafting symbol library and the corresponding
legend. Submitted plans shall follow the City of Springfield Standard Specifications and Standard
drawings related to illumination.
The illumination design may be included on the roadway improvement plans sheets if the project
calls for five luminaires or less. Public improvement projects that have six or more luminaires shall
be drafted on a separate sheet. All illumination plans shall be reviewed by the Transportation
Division for revisions and final acceptance.
5.02.1.B Desil!n Standards
The lighting plan design shall utilize Oregon Department of Transportation (ODOT) drafting
standards. The plans' shall include symbols indicating such features as: conduit, wiring, junction
boxes, power sources, poles, luminaires, luminaire arms, and all the relevant sizes and locations
required to accurately construct the lighting system. For street lighting drafting typicals refer to the
City's latest edition of Standard Construction Specifications and the ODOT drafting symbol/legend
library.
The City standard for street illumination is:
1. Street lighting designs shall be prepared by an engineer capable of performing such work.
The engineer shall be licensed by the State of Oregon. Lighting plans shall be submitted
on sheet devoted exclusively to street light work. Wire size calculations shall be placed
on the last sheet of the plan set. Lighting systems shall comply with the provisions of
National Electric Service Code. Lighting circuits shall be designed to reduce the numb,er
of utility connection points. ;-
2. Lights shall be located in accordance with the Illumination Standards Table (Table 5-1).
In cases that are not defined in Table 5-1 a photometric evaluation of the pole spacing
shall be made using accepted procedures and illumination levels in Illuminating
Engineering Society, American National Standard Practice for Roadway Lighting - RP-8,
most current edition.
3. Intersections shall be illuminated to a level equal to the sum of the average maintained
illuminance ofthe two intersecting streets.

4. Decorative poles and fixtures shall be used on all streets within any Nodal Overlay
district, mixed-use district, and all off street public access ways and multi-use paths. On .
streets that are wider than forty-eight (48) feet from outside curb face to outside curb face
the city traffic engineer may require the use of cobra head style fixtures alone or in
combination with decorative poles and fixtures when deemed beneficial to the public
interest Decorative poles and fixtures may be used on local streets in any zone at the
option of the land developer. All decorative fixtures shall use metal halide lamps.
5. Roadway style "cobra head" fixtures, on standard poles, shall be used in all other
locations. Metal halide or high pressure sodium lamps shall be used as follows:
a. Metal halide lamps shall be used on all Bus Rapid Transit corridors; zones of
Community Commercial, Major Retail Commercial, Campus Industrial, Light
Medium IndustriaV Community Commercial, Booth Kelly Mixed Use, High
Density Residential, and Medical Service.
b. Public Land & Open Space zones shall use the lighting type of adjacent zones so
that continuous light type is achieved.
c. Zones of Medium Density Residential, Low Density Residential, Neighborhood
Commercial, Light Medium Industrial, Special Heavy Industrial, Heavy Industrial,
General Office, and QuarryIMining shall use high pressure sodium lamps.
d. As other zones or overlay districts may be established, the City Traffic Engineer
will determine the lighting type based on similarity to the zones list above and
record it on the "Street Light Type by Zone Map".
6. When roadway style poles are used on arterial streets, in Campus Industrial or Medical
Service zones they shall be steel or aluminum.
.
7. Poles shall be placed at least three feet from the face of curb. Luminaire arms shall be
aligned at right angles from the curb line.
8. In areas where lot frontage is 80 feet or less poles shall be located at or near property lines
'when possible.
9. Conduits shall be electrical PVC with a minimum size of one inch. Roadway crossings
shall have a 1.5 inch minimum diameter. All conduit runs shall be clearly indicated on
the plans showing the route from the power source (typically a SUB vault) to the street
light.
10. Junction boxes shall be placed near the base of each light as shown in Standard Drawing
5-22 (SD 5-22). If the power source is within twenty feet of the street light, this junction
box will notbe required. All junction boxes used for the street lighting system shall have
the words STREET LIGHTING displayed on the metal lid. (See Section 502 ofthe City
Standard Specification for additional details.) Junction boxes shall notbe placed in
sidewalks or ramps. If there are more than four conduit stubs going into the junction box,
the box shall be upgraded to a junction box number 2. Junction boxes located in the
travel way shall be load bearing junction boxes. .

11. All electrical conductors shall be THWN with a: minimum size of Number 12 AGW. A
continuous, groundlbonding wire shall be used in all raceways (conduits) and sized
according to the Code.
12. When provided, the service cabinet shall provide a photoelectric cell, photoelectric
bypass switch, and contactor.
13. Mid-block crosswalks that are approved by the Traffic Engineer shall have two times the
illumination required for the intended roadways.
14. Luminaire poles shall not be placed along the outside of curves.
15. Wood poles shall be Class 4 pressure treated poles.
16. A manufacturer's specification' catalog cut sheet' shall be submitted for all materials for city
review prior to final plans approval.
5.02.1.C Street Li2ht Spacin2
Street lighting shall be engineered and designed to reflect the level of illuminance listed in Table 5-1.
Weak point light = 0.1 foot candles minimum.
