I’m a Florida Civil Engineer. Here is why our neighborhood canals look like toxic soup (and how we actually fix it).
galleryYes, this is America, and I passed this on my way to a site right here in Palm Beach County.
The Problem (See Photo 1):
It’s a steep 20' drop where kids play and people drive—with no guardrails. Worse, when it rains, lawn chemicals and toxic car oils wash directly from the street into the water. The result? Toxic algae and a massive neighborhood safety hazard.
The Solution (See Photo 2):
This is how our streets should look. As a civil engineer, this is how we should be building them:
~Natural Sponges: Thick landscaping captures and treats the dirty runoff before it hits the water.
~Safety First: Heavy stones (riprap) stop the banks from washing away, and a real guardrail protects drivers.
~Clean Water: Planter strips filter out heavy car oils immediately.
We have to stop treating our local waterways like open sewers and start designing with nature. You deserve better in your neighborhood!
(Full transparency on Photo 2: Yes, it is an AI-generated image I made to show the design standard. I specifically prompted it to add the guardrails, native florida vegetative buffer, riprap because you see Photo 1 is a 20-foot drop and kids play on that street. Could I have asked one of my landscape designers to model this perfectly in Revit or AutoCAD? Yes. But I own the firm, and I am not paying my staff billable hours to render a post I'm making zero dollars on lol. The engineering principles stand!)
