Another storm water system, similar to the system at the Fredleyonwhidbey site, is being installed at the Lois remodel. This system, when complete, will have a small stream that will catch all the roof water, directing it to a pond. The pond will overflow into a wetland, where sand for drainage will be added. The wetland will also be planted with filtration sedges. Because the Greenbank site is not sandy, but clay, two additions are being added to the system for "100 year flood" insurance. A path, on the downhill side of the wetland/pond will be a long French drain-type catch basin. On the downhill side of the path a native plant hedgerow of wild roses, snowberry, Oregon grape, salad and ferns will be planted to bind the soil, eliminate any runoff or erosion, and provide wildlife habitat.
Even in the incomplete stages of this system, the water is finding its way to the pond and wetland. The wetland will drain, after a hard rain, after a day or two. With sand and plants, we are hoping to speed up the surface draining to a few hours.
Following are two site pictures of the system in its earliest stages. These pictures were taken after several days of perpetual rain.
