With all the problems involving run-off and high nitrates in the coastal zone, I wonder if retro-fitting some of our yards and town properties to include bioswales and raingardens would be helpful. Some of the blame may go to septic systems, to be sure. But Cape Cod is not immune to our unfortunate desire to have everything covered in blacktop and concrete. I understand the need for parking lots, but can we follow low impact development guidelines, please?
Water gathered through bioswales helps to maintain groundwater levels, and this water will seep in slowly rather than wash away surface soils in a torrent. Obviously (at least to me) one would use native plants and shrubs with deep roots. They are low maintenance and will ameliorate the soil while increasing organic matter. Additionally, native plants = critter habitat.
I know only of one place on the Cape that intentionally integrates bioswales into their grounds design and architecture, namely the IFAW (International Fund for Animal Welfare) headquarters in Yarmouth Port, MA.
Are there other examples on the Cape?
