Horry County Flood Zone Map: How to Check a Property
Use official Horry County and FEMA tools to look up a property’s flood zone. This guide explains what the maps show and what to check next.
Start with the right Horry County flood map
Horry County provides FEMA flood map resources, including maps that show actuarial insurance rate zones and areas identified as having a 100-year flood hazard. [1] For a property lookup, you can also use FEMA’s Map Service Center (MSC) to find an official flood map and access other flood hazard products. [2]
Start with the property’s location. Search or navigate to the address in the MSC, then review the map and any available flood hazard products for that area. The map can help you see how the location relates to mapped flood hazards; it is a starting point for understanding what the maps show, not a complete assessment of every factor that may matter for a property.
For example, if you are checking a home before a visit or comparing two addresses, use the map lookup to identify the mapped information for each location. Keep the address details consistent, and note which map or product you viewed so you can follow up with the relevant source if you need more detail. FEMA describes the MSC as a place to find official flood maps and tools for better understanding flood risk. [2]
A map result is useful context, but avoid treating a quick lookup as the final word on a property’s flood exposure. Check the available map products carefully, and seek property-specific guidance when you need help interpreting what the mapped information means. This section is about where to begin: Horry County’s FEMA map resources and FEMA’s MSC provide ways to view official flood mapping, while the lookup itself helps you understand mapped hazards. [1][2]
Find your property on the map
- Open Horry County’s FEMA flood maps page or the county’s GIS flood map. The county’s FEMA map resource describes its maps as showing insurance rate zones and areas of flood hazard. [1] The GIS page is a map interface, so start there if you want to inspect a location visually. [3]
- Search for the property using the controls available in the map. If you have an address, enter it where the interface offers a search option; if not, zoom toward the general area and use nearby roads or landmarks to orient yourself. The GIS map source lists map controls such as “Zoom to” and “Options,” but does not describe a specific address-search workflow. [3] Check that the map is centered on the correct parcel before interpreting what it shows.
- Review any flood-zone label and base flood elevation information displayed for the location. Horry County’s flood-zone resource identifies “Current FEMA Flood Zone” and “Base Flood Elevation” among its map information. [4] The county’s FEMA map page says the maps include actuarial insurance rate zones and identify areas of 100-year flood hazard. [1] If a detail is not visible at your chosen zoom level, try the map’s available controls or open the related map resource rather than assuming that no designation applies.
- For an official map and additional hazard products, use FEMA’s Map Service Center. FEMA describes the MSC as a place to find an official flood map, access other flood hazard products, and use tools to better understand flood risk. [2] Compare the property location carefully across the county map and FEMA resource. Keep the address or parcel details handy so you can verify that each result refers to the same site. A map lookup is a starting point for understanding the displayed information, not a substitute for checking the specific map products available for the property.
Understand what the map displays
A flood-zone map is a view of mapped hazard information, not a verdict on what will happen to one specific home. FEMA maps include actuarial insurance rate zones and identify areas of 100-year flood hazard. [1] Read the map as context for comparing locations, then check the details for the property you are considering.
What to look for
Horry County’s flood-zone page references FEMA flood zones and base flood elevation. [4] When reviewing a map, note the zone shown for the property and whether a base flood elevation is displayed. These labels help describe the mapped flood information for that location; they do not establish that a property will or will not flood.
For example, if a map shows a flood zone near a house, treat that as a reason to examine the mapped details—not as proof that water has reached the house or will reach it in a future event. Likewise, a location outside an area identified on the map should not be read as a guarantee against flooding. The map describes hazard areas and related information; it does not predict the outcome for an individual property.
Use the map carefully
Check that you are looking at the parcel or location you mean to assess, rather than a nearby street or a broad neighborhood view. A small shift in location can change what part of the map you are interpreting, so zoom in and compare the property’s position with the displayed zone and elevation information. If the map view is unclear, avoid drawing a firm conclusion from the color or boundary alone.
Keep the distinction simple: the map tells you what hazard information is mapped for an area. It cannot, by itself, guarantee whether a particular property will flood. Use it as one part of understanding the location, and describe what it shows rather than assuming more than the map establishes.
Check supplemental and historic flood information
Use the supplemental layer as context
Horry County Flood Mapping describes a proposed Supplemental Flood Zone (SFZ) product that uses historic flood data to map estimated flooding during recent storms. [5] That makes it a useful additional layer to review when you are investigating a property—not a substitute for checking the official FEMA flood map. [5][2]
A practical way to compare the information is to start with the property location, then note what each map is intended to show. Use FEMA’s Map Service Center (MSC) to find the official flood map and explore other flood hazard products and tools for understanding flood risk. [2] Then look at the proposed SFZ as historic-data context about estimated flooding during recent storms. [5] Keep the two results distinct: the SFZ is described as a proposed product, while FEMA’s MSC is the source identified for finding the official flood map. [5][2]
For example, if a property appears in an area of estimated flooding on the SFZ, record that observation and compare it with the official FEMA map rather than treating the SFZ result as an official map determination. [5][2] If the layers show different information, avoid assuming that one cancels out the other; use the FEMA map for the official map and retain the supplemental layer as context. [5][2] Check the FEMA map directly for the property address you are researching.
Keeping the purpose of each product clear helps you compare flood information without confusing a proposed supplemental estimate with the official FEMA map.
Verify details before making a decision
Before relying on a result for a Horry County property, check that the map view is tied to the correct parcel or street address. A nearby pin or a similar street name may lead you to the wrong location, so compare the map’s location with the property details you are checking. If the result does not clearly match, pause and search again rather than treating it as confirmation.
For the official flood map and other flood hazard products, use FEMA’s Map Service Center (MSC). [2] The MSC also offers tools intended to help users understand flood risk. [2] Search using the property’s address or other identifying details, then review the map product for the location you mean. Horry County describes its FEMA flood maps as including actuarial insurance rate zones and identifying areas of 100-year flood hazard. [1]
Keep the map result in context. A search result by itself does not establish an insurance requirement, tell you what a policy would cost, or predict what will happen to a property in a future flood. If you need an insurance decision or price estimate, check with your insurer using the property’s exact location. If one of those questions matters to your decision, verify it with the relevant provider or authority using the exact property location and the appropriate records.
A practical check is to record the address or parcel you searched, confirm that it matches the map location, and note which FEMA product you reviewed. If you are comparing properties, repeat the check for each one instead of carrying a result from one address over to another.
Frequently asked questions
Where can I find an official flood map for Horry County?
Use FEMA’s Map Service Center (MSC) to find an official flood map and access other flood-hazard products and tools for understanding flood risk. [2] Horry County also provides a FEMA Flood Maps page. [1] If you are checking a specific property, search using its location and confirm that the map result matches the property you mean; a nearby address or parcel may not be the same place. Use FEMA’s Map Service Center to find your official flood map and access other flood-hazard products and tools for understanding flood risk.[2]
What does a FEMA flood map show?
The county’s description says FEMA flood maps include actuarial insurance rate zones and identify areas of 100-year flood hazard. [1] In practical terms, use the map to check how a location is categorized, not as a guarantee about what will happen at a particular building. For example, a map result for one part of a property should not automatically be treated as a result for a different part.
Is the Supplemental Flood Zone the same as a FEMA flood map?
No. The proposed Supplemental Flood Zone (SFZ) is described as a unique product that uses historic flood data to map estimated flooding during recent storms. [5] FEMA flood maps, by contrast, are described as including actuarial insurance rate zones and identifying areas of 100-year flood hazard. [1] These descriptions show that the products draw on different information and serve different mapping purposes; do not treat an SFZ result as the same thing as a FEMA map result. For a property check, review the product name shown with the map and use the official FEMA map source when you need the FEMA flood map. [2]
Use the map as a starting point
Use the map as a starting point
For a property check, begin with Horry County’s FEMA flood-map resources, then look up the location in FEMA’s Map Service Center (MSC). The county map information describes actuarial insurance rate zones and areas of 100-year flood hazard; the MSC provides access to official flood maps and other flood-hazard products. [1] [2]
Treat each resource as a different piece of context. The proposed Supplemental Flood Zone (SFZ) uses historic flood data to map estimated flooding during recent storms, so review it separately from the official map rather than treating the two as interchangeable. [5] The supplemental information can help you consider past storm flooding, while the official map is the place to check the mapped flood-hazard details for the location. [5] [2]
When you have a specific property in mind, search for its exact location instead of relying on a broad description such as a neighborhood or nearby road. Check the map details shown for that location and note which resource they come from. A general area can be a useful starting point, but it does not tell you what the map shows for an individual parcel. For example, if two properties are on the same street, check each location separately rather than assuming the same map result applies to both.
A practical next step is to open Horry County’s map resources, use the FEMA MSC to find the official map and related hazard products, and then consult the SFZ as separate historic-flood context. [1] [5] [2] If the result is unclear, gather the exact property location and the map information you reviewed before seeking clarification; do not guess from a general area. This keeps the check focused on the actual location and on what each map product is intended to show.
