Some RestrictionsCoastal Development
Glendale is a landlocked city in the Sonoran Desert with no coastline, so coastal development regulations do not apply. The city has no coastal zone management program, tidal regulations, or beach setback requirements. Water-adjacent development near the Agua Fria River and New River is governed by floodplain regulations, not coastal development rules.

Heavy RestrictionsGrading & Drainage
Glendale requires grading permits for land disturbance activities under the adopted International Building Code and city engineering standards. All development must manage drainage so post-development runoff does not exceed pre-development levels, with stormwater directed to approved retention basins or drainage facilities. The city's relatively flat terrain and alluvial soils require careful attention to retention and sheet flow management.
