Environmental permitting across Maricopa County
Maricopa County is a federal PM10 nonattainment area, so the county Air Quality Department's dust control permit and mitigation-plan requirements apply to earthmoving and construction activity in every city and unincorporated area within the county — not only Phoenix. Sites near a wash, canal, or floodway also fall under Flood Control District of Maricopa County review in addition to city and ADEQ approvals.
An environmental permitting consultant engineer working countywide coordinates ADEQ, Maricopa County Air Quality, Maricopa County Environmental Services, and the Flood Control District, then delivers the PE-stamped drainage, stormwater, or remediation documents each agency requires — wherever in the county the project sits.
