Summary

Outdoor lighting fixtures other than street and pedestrian lights must use dark-sky design with no spillover onto neighboring properties, but the rule applies only inside the Bouldercrest-Cedar Grove-Moreland Overlay District in unincorporated DeKalb County, not countywide.

These county ordinances apply to unincorporated areas of DeKalb County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

All lighting other than street and pedestrian lighting shall have 'dark sky' design - there shall be no spillover from the fixture onto surrounding properties (including the street). All lights and poles shall have a permanent black finish.

c.Ground mounted floodlights shall be screened with planting and shields so light source is not visible. The use of flashing, rotating or oscillating lighting is prohibited if visible from outside the buildings. After hours security lighting shall equal at least twenty-five (25) percent of the normal parking lot lighting level.2.Street furniture. Sidewalks, plazas, parks, trails and other public spaces may contain outdoor furniture such as benches, trash receptacles, bicycle racks and other similar appurtenances. Acceptable street furniture designs are illustrated below. Similar designs may be acceptable if approved by the director of planning and sustainability, provided they are similar in appearance, and meet the following specifications for construction: Color Black Coating/Finishing Steel shotblasted, etched, phosphatized, preheated and electrostatically powered Metal Size Cast ends; ½ × 1½″ steel slats Connections Welds ground and polished to form continuous surface Method of Attachment Bolted to pavement

Full Breakdown

The BCGM Overlay District Design Guidelines, adopted by reference under DeKalb County Code § 27-3.39.6, require that 'all lighting other than street and pedestrian lighting shall have "dark sky" design - there shall be no spillover from the fixture onto surrounding properties (including the street).' Fixtures and poles must carry a permanent black finish, and ground-mounted floodlights must be screened with planting and shields so the light source itself is not visible. The rule governs only the Bouldercrest Road/Moreland Avenue/Cedar Grove Road area of unincorporated DeKalb; it does not apply countywide or inside Dunwoody, Brookhaven, Tucker, Stonecrest, Decatur or the county's other cities.

Non-compliant fixtures within the BCGM Overlay District can block issuance of a certificate of occupancy under Sec. 7.7.15, and violations of chapter 27 are punishable per Code § 1-10, DeKalb County Code § 7.7.17.
