In preparation for the Bucktown Garden walk this weekend, Let’s Go Chicago planted native sedges in the parkway outside Center for Neighborhood Technology’s building at 1741 Western Avenue. The building houses CNT Energy, so the group also learned about Energy’s programs and toured the building. The group’s assistance doing final planting in the garden was key in getting he garden in shape for tomorrow. Pizzo Native Plants donated more plants and Grace Koehler taught the grup about native plants. Thanks everyone!
Peter Hoy is working on the fine grading and the team is checking the depth of our trench. We are creating a green infrastructure drainage solution to trapped water in a gangway. By directing the water to a trench that ends in a dry well in the front yard, the water will no longer be trapped between the houses, causing the house foundations to be unnecessarily moist. This project is a collaboration between Let’s Go Chicago and Semiramis Studio. You may recall the Studio installed several raingardens last fall in associaton with The Center for New Technology. Let’s Go Chicago collaborated on a few of those projects, as well.
The undisturbed subgrade pitches sharply away from the house, encouraging the water to go away from the house, and into the french drain channel. The pea gravel base drains freely and quickly, and also provides a lot of storage area for water interstitially. Pea gravel joints were used in the irregular flagstone area, and for the base material, and around the perforated pipes. Pea gravel at a depth of 6″ nearly eliminates weed growth, and does not subside in rain. Dual 3 inch diameter perforated plastic pipe was used. Since we needed only 50 ft of run and had just enough fall, we doubled it up in the french drain, maximizing the storage capacity, and minimizing cost. Sand jointing was used for the regular bluestone paver area, and the joints were kept to around 3/8″-1/4″ when possible.
Time to go put in another one!
Red Raspberry season is here! Raspberries are nearly zero maintenance and pest-free. The fruit is rarely stolen by birds, squirrels, or other urban critters. I recommend planting yourself a patch. Confining them between a sidewalk and a garage or other barriers keeps them from spreading too much. Delicious!
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.
More info to follow as progress continues!
This patio is in a narrow side yard. Under the patio is a bed of stone allowing the rainwater to escape away frm the house into a french drain running under the far edge of the patio. The materials are a combination of cut bluestone remnants and salvaged sandstone flagstones. When completed, plants along the patio edge will also help soak up stomwater and asist with atormwater infiltration into the soil. We can’t wait to see this space enjoyed!!!
