CITY OF REDMOND APPROVAL PROCESS ---PAGE BREAK--- City of Redmond Illumination Design Manual 7 March 2026 C. System Design: If the existing lighting does not meet standards, guidance on design is detailed in the following section, Design Guidelines. Along with the information in the manual, the Design Engineer shall work with the City to confirm design parameters, fixture, drive current, light loss factors (LLF) and appropriate photometric files. D. Plan Submittals: Typically two plan submittals, the Initial and the Final, will be required by the City. Each submittal shall include one copy of the drawings and other required data. Items submitted shall be in conformance with the applicable portions of Appendix B, Illumination Plan Checklist. Plan sheets shall be submitted as part of the complete civil design package for the project. The civil design package intake will not be accepted for review unless a completed Intake Submittal, as detailed below, is included. 1. Initial Submittal: Material to be presented at the Intake Submittal meeting shall include plan sheets, AGI32 system evaluation of illumination levels, and identification of potential conflicts with utilities or other features and specific areas that may require potholing. See Appendix B for submittal requirements. 2. Final Submittal: Material to be presented at the Final Submittal meeting shall include the remainder of the items required for a complete plan submittal, and response to initial submittal review comments. See Appendix B for submittal requirements; a completed copy of the checklist should be included with the Submittal. Prior to the Final Submittal meeting, it is recommended that the Design Engineer coordinate the effort to pothole critical locations identified during the Intake Submittal. A Right-of-Way Use Permit shall be obtained before commencing potholing. 3. Resubmittal and Approval: If outstanding design issues still exist, the City will require the Design Engineer to submit revised plans for further review and comment prior to approval. The Plans shall contain the Standard City Approval Block in the CCR plans. For PSE-owned lighting improvements, submit PSE construction plan (PSE Work Sketch) with the CCR plans for review and approval by the City. ---PAGE BREAK--- City of Redmond Illumination Design Manual 8 March 2026 III. DESIGN GUIDELINES A. Classification: The system and level of design will depend on project location and adjacent area use. First identify the roadway classification of the roadway segment on which the system will be designed. All roadway classifications are defined in Figure 1. Redmond Roadway Functional Classification map in the City of Redmond Transportation Master Plan. Once the appropriate table has been identified, the adjacent area classification will be determined using the Area Classification map in Appendix A. In addition to this, the lighting designer shall consider the impact of lights on adjacent land uses to the overall illumination of the corridor being designed. B. Facility evaluation extents: Where a half-street improvement is required in conjunction with a development, the roadway width to be used for illumination design purposes will be the actual full width of the roadway at the time of design and not half of the ultimate width. Lighting levels shall be brought up to current standards for the whole width of the roadway adjacent to a new development. This may include installation of new streetlights on the opposite side of the street from the development to bring lighting levels to current standards. C. Type of system to be installed: Light Emitting Diode (LED) systems shall be installed for all new and retrofit designs. Even if the photometric values are met, LED replacement is still required for all lights that contribute to the light levels along the frontage improvements. Details on the type of pole and luminaire to be installed are outlined in Appendix C. D. System layout: Once the acceptable luminaire selection has been made using Appendix C, the appropriate placement parameters must be set. 1. Configuration: The system layout shall be staggered roadway scale lights. The following exceptions are only allowed upon approval by the City: a. Opposite system layout may be specified on wider roadways or to match existing facilities. b. Single-sided systems may be used only if poles cannot be installed on the opposite side of the roadway due to overhead or underground utility conflicts or other obstructions. c. Pedestrian scale lighting may be used in conjunction with roadway scale lights to meet required sidewalk lighting criteria. 2. Spacing: The Design Engineer shall develop the optimum pole spacing for the established criteria as necessary to provide the target illumination levels and Uniformity Ratios (URs). Once optimum pole spacing is established, it shall be adjusted so that: a. No unit is located closer than 5 feet to a driveway. Poles should ideally be placed such that driveways are not located at the darkest point between luminaires. b. A unit is located at the approximate PC/PT at one corner of each unsignalized intersection. c. A unit is located at each corner of a signalized intersection. New luminaires shall be on signal poles. d. A unit is located within 15 feet upstream of a mid-block crosswalk (see section E.2 for more requirements at crossings). ---PAGE BREAK--- City of Redmond Illumination Design Manual 9 March 2026 e. A unit is located such that the centerline to centerline spacing between any adjacent existing or proposed trees shall be as follows: i. 25 feet or equal to the mounting height of roadway light poles; whichever is less. ii. 15 feet or equal to the mounting height of pedestrian light poles; whichever is less. Pole locations shall be adjusted between these control points to provide uniform spacing. 3. Lateral Location: See City of Redmond Standard Detail 420A for guidance on junction box locations and lateral location of poles. In all cases with luminaire arms, the pole shall provide a luminaire overhang of approximately 2 feet from face of curb. See Appendix C for maximum arm a. Where sidewalk is present: pole with luminaire arm shall be located in the planter strip so that the face of the pole is at least 2 ft behind the face of curb. If no planter strip exists, pole with luminaire arm shall be located at the back of sidewalk. Pole with no luminaire arm shall be offset so that the face of the pole is at least 2 ft behind the face of curb. Sidewalk widening may be required to provide required ADA-compliant clearance around the pole. b. Where no sidewalk is present: if curb is present, the face of the pole shall be at least 2 ft behind the face of curb. If no curb is present, the face of the pole shall be 10 ft from the edge of pavement per clear zone requirements per City of Redmond Zoning Code, Appendix 2, Section A.21.c. c. At midblock crossings: the crossing shall be illuminated with two luminaires, each one located upstream (as vehicular traffic approaches the crossing) of the crossing for positive contrast. d. At raised medians: the design engineer shall consider median luminaire placement to meet minimum average light levels. However, any median-mounted luminaire shall meet the clear zone requirements of City of Redmond Zoning Code, Appendix 2, Section A.21.c. E. Lighting Levels: lighting requirements for roadway segments are defined in Appendix C. Other segments of a project shall adhere to the following: 1. Intersections: Intersections shall have a minimum average light level equal to 1.5 times the average light level requirement of the intersecting street with the highest classification. Intersection uniformity shall be less than or equal to the uniformity ratio of the intersecting street with the highest classification. Intersections are defined as locations where two or more roadways meet or cross, creating conflicting traffic movements that require increased driver decision‑making and therefore higher visibility. Private, residential driveways intersecting public streets should not be treated as an intersection. 2. Sidewalks and Crossings: All marked crossings shall be illuminated with at least one luminaire oriented parallel to the crossing. Average maintained light levels within pedestrian facilities shall be as follows: ---PAGE BREAK--- City of Redmond Illumination Design Manual 10 March 2026 Table III-1.
