Summary
Wyandotte County caps light spilling onto residential neighbors at one foot-candle measured at the property line. Sec. 27-699(b)(9) also requires parking-lot, sign, and structure lighting to be deflected away from adjoining residential property, hooded or controlled, and never a bare bulb visible from next door.
(9)Lighting. Any lighting used to illuminate an off-street parking area, sign or other structure shall be arranged as to deflect light away from any adjoining residentially zoned property or from public streets. Direct or sky-reflected glare, from floodlights or commercial operations, shall not be directed into any adjoining property. The source of lights shall be hooded or controlled. Bare incandescent light bulbs shall not be permitted in view of adjacent property or public right-of-way. Any light or combination of lights that cast light on adjacent residentially zoned property shall not exceed one foot candle as measured from said property line.
Full Breakdown
Section 27-699(b)(9) sits in the zoning code's general screening and landscaping standards, applying to commercial, industrial, and other non-residential site lighting anywhere the unified government administers zoning. The rule stacks several requirements: light used to illuminate an off-street parking area, sign, or other structure must be 'arranged as to deflect light away from any adjoining residentially zoned property or from public streets'; direct or sky-reflected glare from floodlights or commercial operations 'shall not be directed into any adjoining property'; the light source itself 'shall be hooded or controlled'; and bare incandescent bulbs are banned wherever they'd be visible from adjacent property or the public right-of-way.
' Because this is the Unified Government's own zoning code, it governs commercial and industrial lighting throughout Wyandotte County and Kansas City, Kansas; Bonner Springs and Edwardsville keep their own separate municipal codes and are not covered by this chapter.
Violations & Fines
A parking lot, sign, or accessory light that isn't hooded, throws glare across the property line, or exceeds one foot-candle at a residential lot line violates Sec. 27-699(b)(9); it is enforced the same way as the other screening standards in that section, such as trash-enclosure and mechanical-equipment screening, through the unified government's zoning code enforcement process.
