The Denver Green Roof Initiative has cleared the petition threshold to make the Nov. 7 ballot. The Denver Elections Division verified 4,771 signatures on their petition as coming from valid registered city voters (4,726 were required to add the measure to the ballot).
The ballot measure would require most new buildings of at least 25,000 square feet to have gardens, solar panels or other “green roof” components cover at least 20 percent of the roof surface:
|Gross Floor Area (Size of Building)||Coverage of Available Roof Space (Size of Green Roof)|
|25,000 – 49,999 f2||20%|
|50,000 – 99,999 f2||30%|
|100,000 – 149,999 f2||40%|
|150,000 – 199,999 f2||50%|
|200,000 f2 or greater||60%|
Existing buildings will be required to install a green roof or combination of green roof and solar at the time of roof replacement. If this would require major structural changes then exceptions would be made.
The Colorado Real Estate Alliance, which includes representatives from ICSC, is leading the campaign against this ballot measure.
