Glendale, Arizona property owners and developers must follow local floodplain building rules to reduce risk to life and property. This guide explains how Glendale regulates construction in mapped floodplains, when a floodplain development permit is needed, which city office enforces the rules, and the practical steps to apply, comply, or appeal.

What the rules cover

The city regulates new construction, substantial improvements, and grading within FEMA-designated floodplains and certain local floodways. Requirements typically include elevating buildings, using flood-resistant materials, and obtaining a floodplain development permit before excavation or construction. For official local program guidance, consult the City of Glendale floodplain management page: Glendale Floodplain Management[1]. For permit procedures and submittal locations, see the city Development Services permit pages: Glendale Development Services - Permits[2].

Always check the city floodplain map before buying or building.

Permits, standards, and required documentation
