Tucson, Arizona requires developers to design projects to manage stormwater runoff, control erosion, and prevent pollution during construction and post-construction. This article summarizes the municipal rules developers must follow, the city offices that enforce them, typical permit and submittal expectations, and practical action steps for compliance. Where official code text or department pages specify details we cite them directly; when numeric fines or form numbers are not published on the official page we note that they are "not specified on the cited page" and provide the source link for verification.[1]
