PLEASE READ BELOW STEPS BEFORE CHECKING THE MAP

Steps:

Enter Address
Allow time for shading to cover map.
If you see BLUE or YELLOW shading on the property, click the shaded area on your property, and a box with “Parcels:” will appear.
In that box along the top right corner you will see an arrow. Click the arrow and you will see flood zone information, including Flood Area ID, Flood Zone, and Static BFE. See below screenshot.

What does the City of Chesapeake map mean?

The map does not show shading or color on the parcel: You are not currently located in a Special Flood Hazard Area. This does not mean you will never flood, only that you are not in the area FEMA identified as high flood risk. There are areas within the City that were not studied by FEMA and are subject to flooding.
The map shows yellow shading: You are located in a 0.2% area with 0.2% Annual Chance Flood Hazard (500 – year storm)
The map shows blue shading: You are located in the Special Flood Hazard Area - Zone AE – 1.0% Annual Chance Flood Hazard (100 – year storm)

Now you are ready to check the map!

Flood zone information is available for online viewing through our Chesapeake Flood Map or through the FEMA Map Service Center.

Elevation Certificates

Elevation Certificates (EC) – are used to rate a home’s flood risk by comparing the elevation of the first floor, or lowest horizontal structural member, to the Base Flood Elevation (BFE) found on the Flood Insurance Rate Map (FIRM). Chesapeake requires an elevation certificate (EC) be provided for all new development, additions or substantial improvements to properties in the floodplain. ECs are received at the completion of the project and reviewed for compliance by staff. It should be noted that Chesapeake did not retain ECs as part of the building permit records because the Virginia Records Retention Act required these documents to be destroyed as part of the records disposal procedures. This was brought to FEMA's attention in June 2010.

Request Copies – Development and Permits provides copies of elevation certificates upon request, electronically, or printed copies. A request can be emailed to the Department’s general email account at develop-permits@cityofchesapeake.net, the Customer Call Center at 757-382-CITY, or by telephone to the Development and Permits Department at 757-382-6018. The request information is also available on the City’s website.

Key Terms

Floodplain	Any land area susceptible to being inundated by water from any source.
Special Flood Hazard Area (SFHA)	SFHA – the land in the floodplain subject to a 1% or greater chance of being flooded in any given year as set forth in the FIRM
FIRM	Flood Insurance Rate Map - The official map of a community on with FEMA has delineated both the special hazard areas and the risk premium zones applicable to the community.
Finished Floor	The City's ordinance requires a minimum Finished Floor height of 1.5 feet above the Base Flood Elevation. A floor that can be inhabited, not a storage area like a garage. This standard also applies to outdoor equipment, such as HVAC units. This is not necessarily the elevation and/or height/level of the ground.
Base Flood Elevation	Base flood elevation can be determined by locating the property on the FIRM map and identifying the special AE Elevation
Zone AE and A1-30	Areas subject to inundation by the 1-percent-annual change flood event determined by detailed methods. BFE (BFEs) are shown. Mandatory flood insurance purchase requirements and floodplain management standards apply.
Critical Infrastructure	Building such as government facilities, hazardous materials facilities, hospitals, power plants, transportation facilities (not to include local streets and roads), etc. Read more information
Flood Proofing	Any combination of structural and non-structural additions, changes or adjustments to structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitary facilities, structures and their concerns.
Freeboard	A factor of safety usually expressed in feet above a flood level for purposes of floodplain management. "Freeboard" tends to compensate for the many unknown factors that could contribute to flood heights greater than the height calculated for a selected size flood and floodway conditions, such as wave action, bridge openings, and the hydrological effects of urbanization in the watershed.
Regulatory flood protection elevation	Refers to an elevation one and a half (1.5) feet above the 100 year floodplain base flood elevation.

How the floodplain ordinance is applied: New construction-structures for which the start of construction commenced on or after August 16, 2013, the date this floodplain ordinance was adopted and includes any subsequent improvements to such structures. Any construction started after February 2, 1977 and before July 16, 2013, is subject to the ordinance in effect at the time the permit was issued, provided the start of construction was within 180 days of permit issuance.

All construction in the special flood hazard areas must meet the requirements of the floodplain management ordinance in addition to the requirement of the Uniform Statewide Building Code. Some of the requirements are outlined in the R- 5 Residential Plan Review Information, which can be found on our Forms and Applications page.
