Overview

Brownfield cleanup in Deer Valley is primarily implemented through state programs and overseen locally by the City of Phoenix planning and development offices for properties inside city limits. Developers commonly use the Arizona Department of Environmental Quality (ADEQ) Voluntary Remediation Program to document cleanup and obtain liability protections; federal brownfields grants and technical assistance may also support assessment and cleanup planning.ADEQ Voluntary Remediation Program[1] For local permitting, the City of Phoenix Planning & Development Department coordinates site review and building permits for Deer Valley properties.City of Phoenix Planning & Development[3]
