What is stormwater pollution?

Every time it rains, trash, bacteria, heavy metals, and other pollutants are washed from city streets and roofs into local streams and the harbor.

Impervious surfaces – including roofs, streets, and sidewalks – keep rain from soaking into the ground and being treated by plants and trees. Instead ,this untreated, polluted stormwater washes straight into nearby streams. 

Sadly, stormwater runoff is one of the fastest growing sources of pollution in Baltimore and the Chesapeake Bay. 


How do we work to curb stormwater pollution?

From organizing community tree plantings to installing rain gardens, our work directly helps to reduce stormwater pollution. Our programs focus on community-based restoration, advocacy, and education to achieve clean water in Baltimore’s watersheds.

One Water Partnership helps religious groups identify and implement stormwater reduction practices. Our Ecoliteracy programs provide ways for all ages to learn how they can help tackle pollution locally. 


Green Stormwater Infrastructure

Green stormwater infrastructure is a cost-effective way to combat stormwater runoff and pollution. Green roofs, rain gardens, and pervious pavement are all examples of green stormwater infrastructure. Why is it so great? Green stormwater infrastructure can help: 

  • Reduce flooding and erosion
  • Make our air cleaner and improve air quality
  • Build climate change resilience
  • Reduce urban heat and keep our neighborhoods cooler
