If you own property in Oklahoma City, there's a strong chance you've encountered the term FEMA elevation survey—especially if you live near the North Canadian River, Lake Overholser, or in flood-prone neighborhoods like Del City or Midwest City.
As Oklahoma's weather becomes more unpredictable and flood management becomes stricter, local property owners are finding themselves needing official elevation data for insurance, permits, or FEMA documentation.
🌧️Why Elevation Surveys Matter in Oklahoma City
An elevation survey measures how high your property sits in relation to the closest floodplain. FEMA uses this data to determine flood insurance requirements, zoning limitations, and the need for additional flood protection.
If your structure falls within a Special Flood Hazard Area (SFHA), FEMA may require you to provide elevation data to:
Qualify for lower flood insurance premiums
Obtain building permits in at-risk zones
Submit a LOMA (Letter of Map Amendment) or LOMR (Letter of Map Revision) to remove your property from a designated flood zone
🏙️ What’s Changing in OKC Right Now?
In the last year, Oklahoma City has revised several of its stormwater and floodplain management policies, particularly near Capitol Hill, Bethany, and the Valley Brook area. These updates are part of a broader effort to modernize the city’s drainage infrastructure and reduce flood risk—but they also mean more paperwork for homeowners and builders.
New zoning and planning applications now require updated elevation certificates, especially in areas near seasonal creeks, tributaries, and watersheds. If you're planning a remodel or new construction near these zones, an elevation survey is not optional—it’s a must.
📅 When Do You Need an Elevation Survey?
You should consider getting an elevation survey in Oklahoma City if:
Your property is listed in or near a FEMA flood zone
You’re applying for or renewing flood insurance
You're submitting plans to the Oklahoma City Development Services Department
You're requesting a LOMA or LOMR
Your lender, real estate agent, or insurer has flagged your property due to flood risk
Even in areas outside the official flood zones—such as Nichols Hills or The Village—insurance companies may still request elevation data because of past flooding events or updated floodplain boundaries.
✅ What Makes an Elevation Survey FEMA-Compliant?
Not all elevation surveys meet FEMA’s standards. For it to be accepted:
The survey must be completed by a licensed land surveyor in Oklahoma
Elevation data must be based on FEMA’s Base Flood Elevation (BFE) and tied to correct reference points
It must include a completed FEMA Elevation Certificate, using the most recent version
Survey results must accurately show the lowest floor elevation of all buildings on the property
A small error or omission—like the wrong map reference or missing floor elevation—can lead to a rejected submission, which delays your project or insurance policy.
⚠️ Common Mistakes to Avoid in Oklahoma City
Many property owners run into preventable issues when getting an elevation survey. Here are the most common:
Only surveys completed by an Oklahoma-licensed surveyor will be accepted. Be cautious of companies offering "quick fix" surveys from out-of-state providers.
Flood zones and base elevations change. Some areas near Crutcho Creek and South OKC have been recently updated. Make sure your surveyor is using the latest FEMA maps.
FEMA requires elevation data for the lowest floor, not just the ground level. If this is missed, your certificate may be rejected.
During Oklahoma’s spring and fall storms, properties may become temporarily inaccessible. Muddy or flooded sites around Lake Hefner or SW OKC can delay the survey by weeks.
🛠️ How to Get a Reliable Elevation Survey in OKC
Visit FEMA’s Flood Map Service Center or contact the Oklahoma City Planning Department to verify your flood zone status. This will tell you whether a survey is required and what documentation FEMA needs.
Hire a surveyor who understands Oklahoma’s terrain and city policies. Look for one who offers turnkey services, including help with LOMA applications, FEMA paperwork, and insurance coordination.
Clear any obstructions like overgrown brush or junk around your foundation. Make sure crawlspaces and lowest floor areas are accessible. This ensures accurate readings and avoids rescheduling.
Once completed, double-check the FEMA Elevation Certificate. It should:
Be signed and sealed by your surveyor
Match your property address and legal description
Include measurements for all relevant structures on site
If you're unsure about any part, ask your surveyor to walk you through it. A good firm will do this without hesitation.
