“Construction activity” means activities subject to AZPDES construction permits. Currently these include construction projects resulting in land disturbance of one or more acres of land, or which will disturb less than one acre, but is part of a common plan of development or sale that will ultimately disturb one acre or more. Such activities include, but are not limited to, clearing and grubbing, grading, excavating and demolition. (Ord. 1397.18, § 1 (part), 2019)
