Substrate and Hydrology: The substrate is purposely designed to catch storm runoff and then allow it to percolate into the surrounding soil. The bottom is lined with coarse gravel and large rocks. The sides are built up from fill.

Biota: The vegetation at present is mostly herbaceous, dominated by various grasses, including Phleum pratense L and Phalaris arundinacea L. The only woody plant is Comptonia peregrina (L.) J. M. Coult. Hypericum perforatum L is almost woody and common here. For a very small area, the number of species collected is actually quite high, although most are exotic. Many of these are ephemeral in early successional habitats and may not persist more than a year or two. Future vegetation will be highly dependent on what measures (if any) are taken to control the inevitable growth of trees and shrubs.

Cultural: This basin was created in late 2007 to catch storm runoff from an adjacent housing development.
