Small Actions, Big Impact: Managing Stormwater During Hayward’s Rainy Season

As Hayward experiences heavier and more frequent rainstorms this season, it’s more important than ever to understand how stormwater affects our neighborhoods, local creeks, and the Bay. Unlike water from sinks or toilets, stormwater runoff flows directly from streets, sidewalks, and yards into storm drains — which lead to the Bay without being treated. What goes into the street often ends up in our waterways.

During heavy rain, storm drains can quickly become overwhelmed. When drains are blocked by leaves, litter, or debris, water can pool in streets and near homes, increasing the risk of localized flooding. Clearing storm drain inlets near your home—when it’s safe to do so—can help prevent backups and keep water flowing where it’s supposed to go.

Rainwater also picks up pollutants along the way. Trash, pet waste, yard debris, and oil drips from cars can be washed into storm drains and carried into creeks and ultimately San Francisco Bay. These pollutants harm wildlife, degrade water quality, and can contribute to unsafe conditions for people and pets. Simple actions, like picking up pet waste, properly disposing of trash, and avoiding hosing down driveways and trash cans, make a meaningful difference.

Residents can also help by preparing their properties for heavy rain. Make sure downspouts direct water away from foundations, clear gutters before and during the rainy season, and avoid overwatering landscapes. If possible, consider using rain barrels or planting rain-friendly landscaping to help absorb excess water and reduce runoff.

It’s important to remember that storm drains are for rain only. Never pour oil, paint, or chemicals into the street or storm drain. These materials should be taken to a Household Hazardous Waste facility, such as the one at 2091 West Winton Avenue, for proper disposal.

With more intense storms becoming more common, everyone has a role to play in protecting Hayward’s infrastructure, neighborhoods, and environment. By taking a few simple steps during the rainy season, residents can help reduce flooding, protect local waterways, and keep our community safe and resilient.
