An 18-month pilot phase began June 22, 2017 after adoption of Ordinance 16, Series 2017 and ended on December 31, 2018. For all permit applications accepted by the City during the pilot phase, all documentation described in this document was required, and irrigation and landscaping installation requirements needed to be met. During the pilot phase, the City encouraged applicants to meet the 7.5 gallons/season/square-foot water budget, however, failure to meet the Maximum Applied Water Budget during the 18-month pilot phase did not hold up applicant’s building permit and/or certificate of occupancy. Effective January 1, 2019, full compliance with the City of Aspen Water Efficient Landscaping Ordinance and Standards will be required.
