Green Space Rate Study: Denver, Colorado

Residents in the City of Denver, through a ballot initiative, voted in a mandate requiring green roofs on buildings that met a certain size threshold. The Department of Public Health and Environment was tasked with working with a stakeholder group of business leaders and environmentalists and others to develop an ordinance that would meet the intent of the initiative and yet make it workable for developers and property owners. The ordinance also allowed some additional options to meet the intent of the requirement for developers/property owners.
