Cahaba River Society works to restore the River by advocating for clean water, biodiversity, green infrastructure, and natural flows.

Restoring the health of the Cahaba River watershed means doing what is best for all life that depends on it.

What damages your Cahaba River?

Urban growth can strengthen communities, but damage the river.  Replacing forests with paving increases stormwater runoff, erosion, pollution, and flooding, and also prevents groundwater recharge, which reduces water in the river during drought. These are the top threats to our drinking water and to life in the River.

These photos were taken at the intersection of the Cahaba River and Grants Mill Road in Irondale. From left to right, these images show the Cahaba after a rain, on a good day, and during the 2016 drought.

Cahaba River Society works collaboratively with governments, businesses, and civic groups to improve how development projects are designed and built. Green infrastructure stormwater design is essential.

Cahaba River Society is the leading environmental nonprofit expert working with local governments and developers to improve stormwater design for new development. We promote green infrastructure, practices like rain gardens and pervious paving that reduce urban runoff and address the top threats to drinking water and biodiversity.

In 2018, Cahaba River Society won a major success to improve management of urban runoff, the top threat to our drinking water and the River’s freshwater life! Because of our work leading environmental partners, cities and counties in the upper watershed have adopted improved stormwater codes and practices for new development, towards achieving the state’s official goals to reduce stormwater pollution–mud, nutrients, and human disease pathogens.

Because Cahaba River Society has developed relationships as a trusted expert resource for city leaders, in 2018 we were able to work closely in just 6 weeks with Vestavia Hills, Mountain Brook, Homewood, Irondale, and Trussville to greatly improve their stormwater codes.


Recent Achievements:

  • Helped lead 2nd Cahaba Connections Conference – 70+ leaders and citizens learned about Cahaba restoration initiatives and model green infrastructure programs in
  • Served as collaborative resource for river-protective design of 6 development projects and awarded Crowne at Cahaba condominiums for water-smart development
  • Supported the Cahaba Beach Road coalition to defend region’s drinking water and the Little Cahaba River from a proposed Highway 280 cut-through road and bridge
  • Documented to ADEM that the Cahaba’s natural flows have been degraded by urbanization and that ADEM should officially designate the River as “flow impaired”
  • Advised City of Birmingham stakeholder group and drafting of model codes to require improved stormwater management and promote green infrastructure
