Rain garden: After the rain
The saga of the rain garden installation, which was completed late Friday, took a dramatic turn on Saturday when a series of storms swept through Annapolis, causing not one, but three "gully-washers."
The rain garden filled and emptied quickly the first time. Not so quickly the second time. And there was standing water by Saturday night.
A neighbor who has a pretty accurate rain gauge reported that 1 3/4 inches of rain had fallen in Annapolis in about four hours. The rain garden was designed to handle an inch of rain, so it was getting a pretty severe test.
During the third cloudburst, the water did as it was directed to do and emptied out into the street via a small spout lined with rocks. This is to prevent the rain garden from overflowing its berms in a mini version of what happened in New Orleans.
By Sunday morning there was still plenty of water in the rain garden. By Sunday evening, only a cup or so remained, collected in the lowest point. By Monday morning, the rain garden was empty, though certainly it hadn't had time to completely dry out.
In short, the rain garden did its job, collecting the rain from most of my roof and from the slope of the yard.
Jack Dawson of Chesapeake Rainscaping and I have some repairs to make and some more mulching to do, and I suddenly understand why he was so insistent that the plants be planted on the berm, out of the way of the standing water.
Let me know what you think, but I think the rain garden is beautiful right now, with the rock wall and the pebble paths and the airy planting. I can only imagine how wonderful it will look in the spring.
