The Rain Garden was installed last fall, and topped with pine fines mulch for the winter. This spring, we refined the grading and removed most of the mulch for use in other areas.
The soil at this site is extremely sandy, so standing water will be rare. We installed native sedges in the lowest areas of the swale, and they should hold the sandy soil quite well.
Over the next few months, as the plants establish, we’ll introduce the downspout water.
This is the beginning of a larger effort to initiate educational programming at the CNT garden on Western Avenue. Check it out!
Here are some pictures from the party. Also, check out the videos!
Getting Ready for Water…….
The Raingarden Conveyance Channel is being lined with river rocks. The water from the roof will be piped to this lined channel, then will travel to the raingarden basin. The conveyance channel is steeply pitched away from the building to encourage the water to travel away from the building. The Channel is also lined with a geotextile fabric to reduce the ability of water to percolate into the soil and gravel along the building foundation. The river rock lining holds the fabric and looks nice.
Getting Ready for Plants…….
Final grading was performed by raking the planting soil and sculpting it to the final grades. The planting areas were marked with inverted spray paint. Native plant plugs will be installed by volunteers. Pictures of the site planted are coming soon….
Most of the hardscape work is done. Some work is still required to get the pergola finished. Plants should arrive this week and will be installed this weekend by Chicago Conservation Corps!
In addition to the raingarden, the garden also showcases materials re-use and re-purpose. CNT was able to purchase used lumber from the ReBuilding Exchange for the pergola, tables, and benches.
Construction is scheduled for the end of the month. More pictures to follow as work continues!
