Stormwater and Floodplain Management
The purpose of Stormwater and Floodplain Management is to protect the health and welfare of the public from the impacts of flooding by promoting sound floodplain management and the development and maintenance of a cost effective and efficient citywide drainage system.
Floodplain Management - Drainage concerns, ordinances, the design standards and policies manual, Homeowner's guide, FAQ's, and information on severe weather warnings.
An Elevation Certificate is a form that is used by the NFIP (National Flood Insurance Program) to provide supplemental information to that found on a FIRM (Flood Insurance Rate Map).
Submit a request for an Elevation Certificate - The city has certificates on file for most, but not all, structures in a FEMA 100-year floodplain in the city, in the city’s Planning and Development Services Records Department.
Changes to Old Elevation Certificates Prepared by City of Scottsdale Staff - The City of Scottsdale is unable to make any modifications to old elevation certificates prepared by the city. If underwriters are rejecting an old elevation certificate prepared by the City of Scottsdale, a new one will need to be prepared.
