Hillside Lots and the Slippery Slope

City of Phoenix – Hillside

The city of Phoenix requires the review of hillside plans for any project deemed in the hillside development area (those properties having a 10 percent or greater slope). The Landscape Section checks the grading and drainage plans for ordinance requirements, such as height of the building over natural grade, lot coverage, and area of disturbance outside of the roof.

Hillside plans are classified as civil plans and therefore are reviewed under the civil plan review process. For a step-by-step overview of the civil process, please select Civil Plans Review Process. Otherwise, select from the hillside topics listed below for additional information:
