West Richland City Zoning Code

To regulate exterior lighting to avoid unsafe and unpleasant conditions.

To discourage excessive lighting.

To regulate the types of fixtures, lamps and standards installed in the city.

To protect all residential zones from the ill effects of outdoor lighting.

To create a safe environment during hours of darkness.

All new construction proposals for nonresidential projects and all proposals for nonresidential remodeling, redevelopment and/or expansion. These regulations also apply to multifamily development including triplexes, apartments, and rowhouses and to residential common areas

These regulations do not apply to single-family or duplex residential construction.

These regulations do not apply to traffic lights; light standards installed on street rights-of-way; lighting necessary for emergency equipment and work conducted for the health, safety, and welfare of the community; or temporary holiday lighting.

These regulations do not apply to sign lighting (see WRMC Title 19).

These regulations do not apply to safety lighting, hazard warning lighting, or other similar lighting which may be required by state or federal agencies.

All outdoor lights shall include a light source and reflector that controls the light beam so that unshielded light does not extend across any bounding property line between incompatible uses (such as residences) or into the public right-of-way.

Outdoor lighting fixtures shall be designed so that the light source is shielded at any bounding property line except where topographical characteristics make this impossible, but should be downward directional.

Lighting designed to accent landscaping features or architectural elements, including the illumination of pole-mounted flags of the United States, shall be concealed or positioned so that the light source is not visible from adjacent property lines.

Light trespass from nonresidential uses onto adjacent residential zones shall be minimized.

Except for intermittent security lighting on motion detectors, all lights more than seven feet above the ground shall be downward directional lighting. The fixture's housing must be totally opaque. Clear or refractive lenses shall not extend below the housing.

Where practical, exterior lighting installations shall include timers, dimmers, sensors, or photocell controllers that turn the lights off during daylight hours or hours when lighting is not needed, to reduce overall energy consumption and eliminate unneeded lighting.

Exterior lighting installations shall be designed to avoid harsh contrasts in lighting levels.

Fixtures and lighting systems established for safety and security shall be in good working order and shall not be diverted to other uses.

Applications for commercial development, including apartments, will be evaluated by the community development director to determine if a lighting (photometric) plan is required to assess and mitigate impacts. The need for a lighting (photometric) plan will be based on the scope and scale of the project, compatibility with surrounding uses, and anticipated light impacts. If required, the plan will include the following:

For exterior lighting installations and fixtures within 50 feet of a residential zone, the following requirements shall apply:

Parking lots shall comply with the standards of this section in addition to the requirements of Chapter 17.57 WRMC, Off-Street Parking and Loading Standards.

For multilevel parking facilities, the roof level shall be considered an outdoor parking lot.

Lighting shall be designed to provide adequate vision, comfort and safety.

Lighting shall be designed to provide uniform lighting throughout the facility.

Lighting shall be designed to provide the minimum level of lighting necessary for user safety and identification of features.

Lighting shall not cause direct illumination on adjacent or nearby properties and streets. Fixtures shall be adequately shielded to prevent glare from normal viewing angles on adjacent and nearby properties and streets.

Light fixtures shall direct illumination only in a downward direction.

The following mounting height regulations shall apply to open-air parking lot lighting fixtures. Mounting height shall be measured as the vertical distance between the parking surface and the bottom of the lighting fixture:

Where an office, commercial, industrial, or other nonresidential building abuts a lot in a residential district, exterior lighting shall be designed, located, constructed, and maintained to minimize light and reflected light trespass into protected zones.

Where an office, commercial, industrial, or other nonresidential building abuts a lot in a residential district, interior parking structure lighting shall be designed, located, constructed, and maintained so light and reflected light does not spill over or intrude into protected zones. The structure shall be designed and constructed so that light from moving and parked cars within the structure does not spill over or intrude into protected zones.

Lighting levels shall be adequate to facilitate activity in such locations.

To minimize extent of direct glare, light fixtures mounted to canopies shall be recessed so the lens cover does not extend below the bottom surface (ceiling) of the canopy or fixture housing and the emitted light is restrained to 85 degrees or less from vertical (see following illustration).

As an alternative (or supplement) to recessed ceiling lights, indirect lighting may be used where light is beamed upward and then reflected down from the underside of the canopy. When this method is used, light fixtures must be shielded so that direct illumination is focused exclusively on the underside of the canopy.

Lights shall not be mounted on the top or sides (fascias) of the canopy. The sides (fascias of the canopy) shall not be illuminated in a manner other than as prescribed in WRMC Title 19.

Lighting levels for outdoor performance areas, sport and recreation facilities, and playfields shall not exceed by more than five percent the Illuminating Engineering Society of North America (IESNA) published standards for the proposed activity.

Where playing fields or other special activity areas are to be illuminated, lighting fixtures shall be mounted, aimed and shielded so that their beams fall within the primary playing area and immediate surroundings, and so that no direct illumination is directed off the site.

The main lighting shall be turned off as soon as possible following the end of the event.

"Security lighting" is defined as lighting designed and used to discourage crime and undesirable activity.

Security lighting should use the lowest possible illumination to effectively allow surveillance.

The use of sensor technologies, timers or other means to activate lighting in times when it is needed may be required by the city to conserve energy, provide safety, and promote compatibility between different land uses.

In order to direct light downward, all security lighting fixtures shall be full cut-off fixtures.

Lighting shall be shielded and aimed so that illumination is directed to the areas of concern.

Where security lighting is proposed, IESNA minimum and maximum guidelines are to be followed.

Fixtures used to accent architectural features, materials, colors, style of buildings, or art shall be located, aimed and shielded so that light is directed only on those features.

Lighting fixtures shall not generate excessive light levels, cause glare, or direct light beyond the facade onto neighboring property or streets.

Exterior lighting which may be considered a nuisance or hazard may be reduced or restricted or otherwise controlled upon such a determination by the community development director or other authorized administrator. Such action shall be provided to the building owner and/or manager within 10 days of the initial use and inspection of the exterior lighting installation.

Flags of the United States or Washington State may be illuminated from below, provided such lighting is focused primarily on the individual flag or flags.

Navigation and airport lighting required for the safe operation of boats and airplanes.

Emergency lighting required by police, fire, and rescue authorities.

Lighting for state and federal highways authorized by the Washington State Department of Transportation.

Internal lighting of permitted signs.

Outdoor lighting for public monuments.

In-pool lighting for private swimming pools.

Holiday decorations.

Laser source light, strobe lights and similar high intensity light sources, except those associated with approved activities of the city of West Richland. High intensity lights for which a temporary permit is issued shall not project above the horizontal plane nor extend into the public right-of-way.

Searchlights.

All outdoor lighting fixtures existing and legally installed and operative before the effective date of the ordinance codified in this title are exempt from the requirements of this title.

When a nonconforming fixture is replaced, the replacement shall meet the requirements of this title.
