CITY OF KANSAS CITY, MISSOURI SUPPLEMENT TO APWA STANDARD SPECIFICATIONS AND DESIGN CRITERIA SECTION 5800
This is the Kansas City, Missouri Supplement to Section 5800 of the American Public Works Association, Standard Specifications and Design Criteria. The following pages are approved and adopted as replacement pages to the sections and paragraphs of the Kansas City Metropolitan Chapter's APWA, Standard Specifications and Design Criteria (Metro Chapter Standards) that were adopted by the Chapter on December 15th, 1982. The deletions and additions in the following replacement pages that partially revise and supplement the December 1982 Metro Chapter Standards become a part of Section 5800 for use within Kansas City, Missouri. Text that supplements the Metro Chapter Standards is identified by bold italic font. Text that is found in the Metro Chapter Standards text and that does not appear in the following replacement pages, is deleted and not adopted. The City of Kansas City, Missouri, Department of Public Works supplement replacement pages are identified in the bottom-left margin by "KCMO (Adoption-Month Adoption-Year)" and/or by light-blue stock. The supplement replacement pages are numbered and sectioned so as to follow in sequence with the Metro Chapter Standards.

5803.2
5803.5
5803.2 Street and Area Classification: See Section I of the Standard Practice. The designer should consult zoning maps and available future planning documents to assist in area classification. Many municipalities have a major street plan or other documents which classify streets. All plans shall include area and roadway classification. 5803.3 Pavement Classification: See Section 2.3 of the Standard Practice. The designer should consider that Portland cement concrete pavement may lose as much as 50% of its reflective property over its life. The designer should also consider the owner's overlay Pavement practice. classification R3 is usually a good choice. 5803.4 Luminance, Illuminance, Uniformity Ratios, Veiling Luminance, Pedestrian Horizontal Illuminance Values are obtained from Table 2 and 4 of the ANSI IES RP-8 Standard Practice. These are values which are expected to exist at the time of relamping. A. All submittals shall include the following, as set forth in ANSI/IES RP-8, for all unique roadway configurations: 1. 2. 3. 4. 5. 6. 7. 8. 9. average pavement luminance average/minimum luminance ratio maximum/minimum luminance ratio average illuminance average/minimum illuminance ratio maximum/minimum illuminance ratio maximum veiling luminance ratio pedestrian horizontal illuminance pedestrian average/minimum illuminance ratio
Where sidewalks are present or proposed, the average maintained horizontal illuminance on sidewalks should meet or exceed the standards set forth in Table 4 of ANSI/IES RP-8. B. The maintenance factor for major-intermediate, collector-commercial, collector-intermediate and local-commercial shall be 0.54. All other streets (except where industrial areas are in the vicinity of any streets where a maintenance factor of 0.54 applies) shall be 0.68. C. All computer printouts and calculations shall be submitted and luminance, illuminance, veiling luminance and pedestrian illuminance and all uniformity ratios shall be shown on the plans.
5803.5 Uniformity Ratios: In addition to the average to minimum illuminance ratio recommended by the Standard Practice, the maximum to minimum illuminance ratio shall not exceed ten on all except local residential streets. 58-2 KCMO (May 2001)
5803.6
5803.7
5803.6 Mounting Height and Spacing: Sections 3.6 and 3.7 of the Standard Practice offer guidance to the designer. Generally, with well designed luminaires, the mounting height and spacing are selected to achieve the desired uniformity ratio. The lamp size is then selected to provide the desired value of illuminance. Many luminaire manufacturers offer an applications engineering service which may be helpful in determining the optimum mounting height and spacing. Poles should be located in the public right-of-way as near to the side property lines as feasible. A. Pole spacing on residential streets shall not exceed 175 feet. The following uniformity regulators shall apply: 1. No spacing shall differ from an adjacent spacing by more than 7 percent 2. No individual spacing in a given block shall differ from the average for that block by more than 8 percent 3. The average spacing in any block shall not differ from the average spacing in an adjacent block by more than 5 percent. B. Narrow roads shall be designed to have uniform spacing using only one side, while wider roads shall use opposite spacing. There shall be no staggered spacing or randomly located streetlights other than at intersections.
5803.7 Pole Setback: In general, the pole setback from the curb should be selected to help prevent the pole from being struck by a vehicle. This should be eight or more feet on heavily traveled streets. An appropriate length mounting arm to put the luminaire at or near the curb should be specified. On limited access roadways, the use of breakaway pole bases is recommended. Guardrail can also be used to prevent a vehicle from striking the pole.

5804.1 SECTION 5804 ELECTRICAL SYSTEM
5804.3
5804.1 General: The electrical system shall comply with the standards listed in Section 5802.2 and service standards issued by the utility which will be supplying power to the street light system. A. All plans shall include: 1. Voltage drop calculations 2. One line schematic with circuit loading, breakers details 3. Wire sizing, conduit and insulation type, and fusing details 4. Routing of circuits relative to existing utilities, burial depth, conduit size and type, and locations, etc. B. All poles shall be numbered to ensure that any new streetlights installed is uniformly identified. The City shall assign pole numbers to each streetlight at the time of the plan review and the design engineer shall place the numbers on the final approved construction drawings.
5804.2 Feed Point: The feed point location shall be coordinated with the utility to insure availability of service. The load should be adjusted to take advantage of the rate schedule and secure the most economical rate. The main fuse or circuit breaker shall be capable of interrupting the maximum fault current expected at the service location, but in no case less than 65.000 amperes. 5804.3 Distribution System: All new circuitry shall be underground and 240 volts. Cables shall be sized so that the voltage drop does not exceed five percent at any point in the system. Conductors shall be no larger than 1/0 AWG or no smaller than #8 AWG.
