6. Recommendations   BUG rating for each luminaire type, including for any variations in lamping and shielding. Color information (CCT and CRI). Coordination with Utility Providers The jurisdictions should coordinate with the utility providers to retrofit lighting at publicly‐owned facilities, particularly those with large parking lots to provide new luminaires that meet the following requirements: The Lighting Plan should include calculation summaries demonstrating compliance with both Limits to Off Site Impacts and Total Site Lumen Limit. Both allowances and proposed values should be provided. For residential projects, lighting information should be submitted in the form of drawings and light source information, including location, shielding and controls. Lighting Audits The requirements of the MLO were constructed with enforcement in mind. The typical procedure involves demonstration of compliance with the applicable lighting code requirements to the planning department during permitting. Should the enforcing organization decide to audit a property for conformance, the procedure would involve checking the installed lighting equipment in reference to the submitted information in the plan. No on‐site lighting measurements would be necessary. Coordination with Georgia Power While the recommended lighting ordinance changes will assist with lighting that supports the flying mission at Dobbins ARB, it is also recommended that the jurisdictions work with Georgia Power on efforts to educate the public on opportunities and cost savings associated with retrofitting lighting in private developments, particularly those with large parking lots. Although intended to provide cost savings to private property owners, the technologies and systems used in retrofits by Georgia Power have a positive byproduct of reducing light pollution. March 2018  Consistent color temperature of the lights.  Color temperatures do not exceed 4100K (white light).  Lights are fully shielded.  No light is emitted above 90 degrees.  Appropriate amount of light where needed.  Glare restrictions are in place. New and retrofitted lighting to reduce light pollution as part of roadway and highway improvements, including lighting for pedestrian circulation, should also be considered. Roadways under the purview of local jurisdictions, should be retrofitted with luminaires that achieve the performance standards recommended in the bullets above. High mast highway lighting under the authority of GDOT uses 400W high‐pressure sodium (HPS) luminaires, which have a hue that is generally yellow or pink. Coordination with GDOT to replace this lighting with LED luminaires should be planned and budgeted for by local jurisdictions and pursued through a cost sharing agreement with GDOT.
