Sandy Springs to Assess Floodplain, Redraws Maps
In the United States and in Georgia, flooding is the number one natural disaster. To identify flood hazards and the risks they pose, the Federal Emergency Management Agency (FEMA) develops flood hazard maps, officially known as Flood Insurance Rate Maps or FIRMS.
FEMA is now working with the State and the City of Sandy Springs to update or revise the FIRMS from Buford Dam to Coweta County, which includes the City of Sandy Springs. This will produce a better assessment of the Chattahoochee River Basin’s current flood risk and will allow officials to develop a more comprehensive approach to mitigate damage brought on by flooding.

Why should you care about clean water?
Imagine no longer being able to fish, swim or wade through your favorite stream, river or lake. It might surprise you, but many waters in the metro Atlanta area are degraded due to polluted runoff after a rainfall.
Each time it rains, stormwater runoff (rainfall that does not soak into the ground) picks up debris such as litter, pesticides, chemicals, motor oil and dirt as it flows across rooftops and lawns, streets and parking lots. These pollutants are deposited, untreated, into our waterways. Increased runoff from developed areas can also cause flooding and erosion of stream banks, which results in even more pollutants entering our streams. Stormwater pollution can make monitoring and treatment of our drinking water more difficult and costly. In addition, it can harm our aquatic environment and ruin the beauty of our streams. If polluted stormwater contaminates our water sources, the result can be the closing of our rivers, lakes and streams to the public.
10 things you can do to “be a solution to water pollution”
Never dump anything on the street, down a storm drain or in a drainage ditch.
Scoop up after your pet. Bag the refuse and dispose of it in the trash.
Compost grass clippings and leaves or bag them for curbside collection. Do not blow them into the street.
Use fertilizers and pesticides sparingly. Do not apply them on paved areas.
Check your vehicles for leaks and repair them.
Reduce, reuse and recycle the amount of cleaning and maintenance chemicals used at home.
Recycle motor oil and other vehicle fluids.
Put litter in its place.
Wash cars at a commercial car wash or on a grassy area and not your driveway.
Tell a friend or neighbor about how to prevent stormwater pollution and get involved.
Did you know?
The quality of metro Atlanta’s streams, rivers and lakes are threatened by the daily activities of residents and businesses across the region. The leading threat to our water quality is stormwater pollution. Fifty-nine stream miles in the City (more than 1,000 in Metro Atlanta) are in violation of water quality standards due to stormwater pollution. The only way to combat the adverse effects of pollution is through knowledge and action.
