Another thread just brought this to mind. During re-cert propaganda exposure last month, the topic of "Rain Gardens" came up. Basically, this is a wet area planting designed to slow the flow of rain run-off and filter it through an approved soil/root system to pull out silt and contaminants. Apparently, some jurisdictions are offering a sort of subsidy or tax break for homeowners and commercial properties which incorporate them into their landscape, but it's Spring and I haven't really had the time to run this one down. Anyone familiar with this? It has to be one of the biggest gifts the government has ever handed us. The marketability of this is mind-boggling.
