Quick Facts
- Flood control zones are areas designated to manage and regulate water flow during heavy rainfall or storm events.
- These zones help to prevent flooding in nearby communities and protect infrastructure from damage.
- Flood control zones can include natural areas like wetlands, rivers, and streams, as well as man-made structures like levees and dams.
- The main goal of flood control zones is to absorb excess water and slowly release it back into the environment.
- Flood control zones can also provide habitat for wildlife and help to maintain water quality.
- There are different types of flood control zones, including floodplains, floodways, and regulatory floodways.
- Flood control zones are often managed by government agencies, such as the US Army Corps of Engineers.
- The mapping of flood control zones is typically done using geographic information systems (GIS) and remote sensing technologies.
- Flood control zones can be used in conjunction with other flood mitigation strategies, such as flood-proofing buildings and implementing early warning systems.
- The effectiveness of flood control zones depends on factors like land use, soil type, and vegetation cover.
Introduction to Flood Control Zones
As a real estate company in Hawaii, understanding flood control zones is crucial for both residents and buyers. Hawaii is a tropical paradise, but its unique geography and climate make it susceptible to flooding, landslides, and other natural disasters. In this article, we’ll delve into the world of flood control zones, explore the risks, and discuss the precautions you can take to protect yourself and your property.
What are Flood Control Zones?
Flood control zones are areas that are prone to flooding due to a variety of factors, including heavy rainfall, coastal erosion, and storm surges. These areas are typically designated by government agencies, such as the Federal Emergency Management Agency (FEMA) in the United States. In Hawaii, the state government, counties, and local authorities collaborate to identify and mitigate flood risks.
Types of Flood Control Zones
There are several types of flood control zones, including:
- Special Flood Hazard Areas (SFHAs): These areas are at high risk of flooding and are designated by FEMA as having a 1% or greater chance of flooding each year.
- Flood Zone A: These areas are typically coastal or riverine areas that are at high risk of flooding and are often subject to flooding from storm surges or heavy rainfall.
- Flood Zone AE: These areas are typically inland areas that are at moderate risk of flooding and are often subject to flooding from heavy rainfall or snowmelt.
- Flood Zone X: These areas are typically areas that are not at risk of flooding and are often used for residential or commercial development.
How to Determine if a Property is in a Flood Control Zone
To determine if a property is in a flood control zone, you can:
- Check the property’s location on a map: Look for a flood zone designation on a map, such as a FEMA flood map or a local government’s flood map.
- Consult with local authorities: Contact the local government or a licensed real estate agent to ask about flood risks in a particular area.
- Order a flood report: A flood report can provide detailed information about a property’s flood risks, including the depth of flooding and the frequency of flooding events.
Flood Risk and Home Prices
If a property is located in a flood control zone, it can affect its value. Properties in high-risk flood zones, such as SFHAs, may have lower property values due to increased flood insurance costs and potential flooding risks.
| Flood Zone | Median Home Price (2023) | Annual Flood Insurance Cost (2023) |
|---|---|---|
| SFHA | $450,000 | $2,500 – $5,000 per year |
| Flood Zone A | $400,000 | $1,500 – $3,000 per year |
| Flood Zone AE | $350,000 | $500 – $1,500 per year |
| Flood Zone X | $600,000 | $0 – $500 per year |
Flood Prevention and Mitigation Measures
While flood control zones can be a concern, there are measures that can be taken to prevent and mitigate flood damage:
- Levees and floodwalls: Constructing levees and floodwalls can help prevent flooding and protect properties from damage.
- Wetland restoration: Restoring wetlands can help absorb excess rainfall and reduce flood risks.
- Stormwater management: Implementing stormwater management systems, such as detention ponds and green infrastructure, can help reduce flooding and improve water quality.

- What are the different types of flood control zones? There are several types of flood control zones, including:
- Floodway zones, which are areas where floodwaters flow and are typically restricted from development.
- Floodplain zones, which are areas surrounding floodways where floodwaters may overflow.
- Coastal erosion zones, which are areas prone to erosion from coastal flooding.
- Why are flood control zones important? Flood control zones are important because they help to:
- Reduce the risk of flooding and associated damage to properties and infrastructure.
- Protect public health and safety by preventing development in areas that may be hazardous.
- Preserve natural floodplains and wetlands that provide important ecological functions.
- How are flood control zones designated? Flood control zones are typically designated by local or national authorities using a combination of:
- Topographic mapping to identify areas prone to flooding.
- Hydrologic modeling to predict flood frequencies and severity.
- Field observations and measurements to validate flood risk.
- What are the restrictions in flood control zones? The restrictions in flood control zones vary depending on the type of zone and the level of flood risk, but may include:
- Limits on building heights and densities.
- Requirements for floodproofing or elevating structures.
- Prohibitions on certain types of development, such as residential or commercial construction.
- Requirements for permits and approvals before development can occur.
- How can I determine if my property is in a flood control zone? You can determine if your property is in a flood control zone by:
- Contacting your local planning or zoning department.
- Checking online mapping tools or floodplain maps.
- Reviewing your property deed or title report for flood zone designations.
- What are the consequences of developing in a flood control zone without permission? Developing in a flood control zone without permission can result in:

For Buyers & Sellers
As a homeowner or prospective buyer, understanding the impact of flood control zones on your property can be a daunting and costly consideration. Flood control zones, also known as Flood Zone Maps (FZMs), are used by the Federal Emergency Management Agency (FEMA) to indicate areas that are at risk of flooding.
The Impact on Home Buyers:
As a homebuyer, understanding the flood control zone of a property can significantly impact your decision-making process. If a property is located in a High-Hazard Flood Zone (FHL), which is the most flood-prone zone, it may be more difficult to secure a mortgage or finance a purchase. This is because lenders are often hesitant to lend in these areas due to the increased risk of flooding and potential long-term maintenance costs.
Additionally, homebuyers who live in areas with high flood risk may face higher insurance premiums, increased maintenance costs, and potential disruption to their daily lives due to flooding.
The Impact on Home Sellers:
As a homeowner looking to sell your property, understanding the flood control zone of your home is crucial. If your property is located in a Low-Hazard Flood Zone (FL), you may be able to market your home as a more desirable option, reducing the risk of a buyer requesting additional inspections or requesting a lower price due to flood concerns.
However, if your property is located in a High-Hazard Flood Zone, you may need to disclose this information to potential buyers, which could negatively impact your sale price. In some cases, homes in these areas may be deemed unsellable or may require significant renovations to mitigate flood risk.
Key Factors to Consider:
- The level of flood risk in your area, as indicated by the Flood Zone Map.
- Your insurance costs and options.
- The potential for long-term maintenance and repair costs.
- The impact on resale value and saleability.
- The need for flood mitigation measures, such as elevating your home or installing flood-proof doors and windows.
Ultimately, as a homebuyer or seller, it’s essential to understand the impact of flood control zones on your property and to factor these costs and risks into your decision-making process.
