Lamps are on tall light poles that tower far above the roof of any house and since the fixtures radiate sideways and not down all of our rooftops are brightly lit all night


Solutions

bull Light pollution is a regional issue Think Regionally BUT ACT LOCALLY

bull A County Resolution

Recommendations Ideas Next Stepshellip

A promise to raise awareness and seek solutions bull An Dark-Sky amp Starlight Awareness Week (or Month)

- If the State of Illinois did why canrsquot we

bull Form an Outdoor Lighting Advisory Board - To analyze the problem seek input from experts and stakeholders and

develop an ordinance - Review existing and IDAIESNA MLOs including lessons learned by others

bull Review current county regional sustainable initiatives - Take advantages of these windows of opportunity to light up responsibly - Are any recommending unnecessary intrusive harmful lighting

Recommendations

bull Make use of lighting modeling software tools httpapps1eereenergygovbuildingstools_directory

Is a Street Complete if it has excess wasteful harmful lighting If it lights beyond where intended If it trespasses to another property If it causes glare and makes driving walking unsafe If it contributes to sky glow spills into our national parks If it endangers wildlife causes health issues

Letrsquos make our Streets Truly Complete my Lighting them Responsibly

A Success Story Cook County IL

10262011 ndash First contact to Cook Co

1212011 starlight proposal amp testimony at FFDCC budget hearing
