Flooding is the most common natural disaster in the United States. Here in Pittsburgh, our waterways, hills, and valleys mean we're no strangers with the concept of occasional floods. Since spring and summer rains increase the risk of stream and river flooding, street flooding, and sewage backups, we suggest taking the following steps today to prepare.
- Make an emergency plan for your household, including pets, so that you and your family know what to do and where to go.
- Sign up or listen for emergency and weather alerts. Remember: never walk, swim, or drive through floodwaters.
- Look up the flood risk for your home. Store important documents and valuables in a safe, dry place. Elevate and anchor critical utilities like electrical panels and propane tanks.
- Purchase or renew a flood insurance policy through the National Flood Insurance Program (NFIP).
- Take photos of your property and do an inventory in case of damage.
Managing the Impact of Stormwater
In addition to these preparatory measures, there are many preventative actions you can take around the home and in the garden to better manage stormwater runoff and help mitigate the impact of flood-producing weather systems.
- Installing rain gardens—areas filled with specialized native plants and soils that absorb excess water—helps to slow and filter runoff, while also preventing pooling on your property and reducing the likelihood of a wet basement.
- Permeable pavements, such as porous concrete or pavers with gaps, allow water to seep into the ground rather than move quickly over hard surfaces, which prevents overwhelming the storm sewer systems.
- Rain barrels or cisterns can capture rooftop runoff, providing a useful water supply for gardens or lawns while reducing excess stormwater runoff from your property.
- Keeping gutters, downspouts, and storm drains clear of leaves and debris ensures proper water flow and prevents blockages that could lead to backups and flooding.
- Proper grading—sloping your yard away from your home—directs water safely outward rather than allowing it to pool near the foundation. This prevents basement flooding.
- Installing backwater valves can further protect against sewer backups during heavy storms.
By incorporating these strategies, you can not only safeguard your property, but also contribute to a more resilient neighborhood by reducing the burden on stormwater systems and decreasing the likelihood of localized flooding. These small, proactive measures add up to a stronger, stormwater-ready city!
