Aaron Kauffman (SW Urban Hydrology and previous Land and Water Summit speaker/tour guide) and Cody Stropki (SWCA Environmental Consultants) just published a study on soil moisture in Santa Fe rain gardens over a seven year period. It presents some excellent data to make the case for rain gardens. Definitely worth a read and please share!
