Can I build stormwater retention trench so I can park on top of it?
We are building on a small lot, and are required to locate a 10’x10’x2′ stormwater retention trench in a location ideal for parking. I’ve been researching the base prep for permeable paving, and much of it looks similar to the stormwater retention trench: 12″-18″ layers of triple washed gravel, overflow pipes, judicious use of filter cloth. Can anyone point out issues that would arise from doubling the base layer and otherwise building the stormwater retention area as we would a permeable driveway?
