Should you buy a house in a flood zone? It can be a sound purchase if you know which zone, what insurance will cost and what your lender requires. Homes in a FEMA Special Flood Hazard Area (zones starting with A or V) need flood insurance when bought with a government-backed mortgage. Homes in Zone X usually don't, though a lender can still require it.
What's different in Scottsdale? The city participates in FEMA's discount program: Scottsdale says flood insurance policies get 20% off a general policy and 5% off a reduced-risk policy. And much of central Scottsdale sits beside the Indian Bend Wash, a flood control channel the county says provides 100-year flood protection for a 65-square-mile drainage area.
Data note: Insurance rules come from FEMA's National Flood Insurance Program (NFIP) and federal regulations. Local details come from the City of Scottsdale and the Flood Control District of Maricopa County. General information, not insurance or legal advice.
FEMA Flood Zones in Plain English
From the City of Scottsdale's flood zone guide:
- Zone A / AE: Special Flood Hazard Area inundated by the 100-year flood; AE has base flood elevations
- Zone AO: 100-year flood area with 1 to 3 feet of depth, usually sheet flow on sloping terrain
- Zone AH: 100-year flood area with 1 to 3 feet of depth, usually ponding
- Zone X (shaded): the 500-year flood area, or areas with shallow 100-year flooding or protected by levees
- Zone X (unshaded): outside the 500-year floodplain
FEMA notes that SFHAs appear on maps as zones beginning with A, AE, V or VE, with V zones used for coastal areas.
Will You Need Flood Insurance?
Required
- FEMA says lenders require flood insurance for homes inside an SFHA with a government-backed loan. This is the mandatory purchase requirement
Possibly Required
- Lenders may require coverage in any area, even outside an SFHA. FEMA recommends confirming the lender's requirement before you buy to avoid closing delays
Worth Considering Anyway
- FEMA says almost one-third of NFIP claims from 2014 to 2024 came from areas outside current high-risk flood areas
- Standard homeowners policies typically don't cover flood
Timing: The 30-Day Wait and the Closing Exception
- NFIP policies typically take effect after a 30-day waiting period
- No waiting period applies when coverage is bought in connection with making, increasing, extending or renewing a mortgage loan, as long as it's applied and paid for at or before closing (44 CFR 61.11)
- A seller can transfer an existing policy to the buyer, with or without a mortgage
Elevation Certificates
An Elevation Certificate is optional but can lower premiums. FEMA says you can ask the local building permit office, the previous owner or a flood insurance agent whether one exists, or hire a licensed surveyor, engineer or architect.
The Indian Bend Wash: Central Scottsdale's Flood Control
The greenbelt that defines life around Chaparral Park is also infrastructure. Per the 2024 Scottsdale Flood Response Plan by the Flood Control District of Maricopa County:
- Built by a partnership of the District, the U.S. Army Corps of Engineers, the City of Scottsdale and private developers
- Runs from Indian Bend Road south to the Salt River
- The greenbelt section, between McDonald Drive and McKellips Road, is a 4.5-mile grassy swale used for parks, golf courses, trails and ball fields
- Serves a 65-square-mile drainage area and provides 100-year flood protection
- Completed in 1985

Your 85250 Due-Diligence Checklist
- Look up the parcel on FEMA's Flood Map Service Center or Scottsdale's interactive maps
- Read the seller's disclosure: the SPDS asks about flood plains and past flooding (see our SPDS guide)
- Get a flood insurance quote during your inspection period
- Ask about an Elevation Certificate and any existing policy the seller can transfer
- Call the city with questions: the Scottsdale Stormwater Group, 480-312-7740
- Watch for map changes: Scottsdale says affected residents typically receive a letter when FEMA revises a map
“Flood zone is a phrase that makes buyers nervous, and I understand why. But in 85250 the answer is usually in the details: which zone, what the quote looks like and what the lender needs. I have my buyers pull the flood map and an insurance quote early so there are no surprises at closing.”
