The next part of the project will involve installing a pool at the top of the catchment area to slow incoming water and direct it south along the swale along the road and west downhill into the flower bed. Both areas are lined with drainrock and then larger tumbled round rock will be laid in on top. For the catchment pool we had to pull out one of the cotoneaster shrubs, remove the stump and then back fill with soil and drainrock.
As we were working on the rain garden/french drain project we got more material donated to us from a project at the College of Environmental Design project: Trex, a recycled plastic edging board and some drainage rock to replace the rotted existing edging. As we took the opportunity to reuse the recycled materials, we made the swale wider and deeper to hold more runoff rainwater and we are also regrading the road with the road base cut from the edge of the road.
Structures that were built out of donated timber bamboo from the garden and recycled fabric hold Coast live oak trees that will be planted by College of Environmental Design students taught by Professors Walter Hood and Ron Rael in locations around Oakland.
