Lately, I’ve been diving into impact assessments concerning water quality in urban areas. It’s surprising how much contamination can stem from runoff. I’m looking for sustainable solutions or case studies that you all have found effective in mitigating these issues. Any insights or resources to share?
I’ve seen green infrastructure work well in urban settings to manage runoff. Have you explored using bioswales or rain gardens? They can be pretty effective!

Urban runoff can be tricky, like trying to keep a cat out of a bath; have you checked out permeable pavements? They can really help with managing that runoff effectively. @james_carter47, what do you think about incorporating those with green roofs?
I’ve found that combining green roofs with rain gardens can be really effective, as the roofs reduce runoff while the gardens filter stormwater. Have you looked into that approach, @woodrow_all39? It might offer some additional insights.
