Thinking about the upcoming Rain Gardens meetup

Gardeners greatly affect the ocean, and we do so in two distinct ways. First, we influence the amount of water running off a landscape. Between 30% and 80% of an urban/suburban homesite is comprised of impermeable surfaces, and besides the roof, most of this area can be changed. And second we influence the quality of water running off our properties and landscapes. Rain falling into an ocean is not inherently harmful, it is the stuff attached to it that is. Fertilizers, pesticides, oils, cleaning solutions, and organic debris all runs off our landscapes during rain. These chemicals and organic substances are the culprits that encourage harmful algae and bacteria.

CPR stands for Conservation, Permeability, and Retention, and when fully employed, it has one of two outcomes: Water run-off is either eliminated or cleaned.

Good Stuff, Dave. Ultimately many of us may want to capture rainwater for irrigation or even for filtration and drinking. But rain gardens et al have an important role in the CPR approach. Very excited to learn more.
