|Rain garden ready for runoff|
Within a few days we had a good heavy rain and the customer sent me these photo updates. At 5am the customer was watching water go over the emergency spillway. This happens when it's rains more than it would 90 percent of the time. The spillways are installed to maintain the integrity of the construction and designed to prevent point erosion.
Here is the garden at 9am holding a good amount of storm water from rushing into the nearby lake where it would increase the storm surge, along with erosion/sediment and other potential pollutants.
|9am quite a bit of water|
By Noon some water had infiltrated but still a lot in there. Plants are selected for their ability to thrive in both wet and dry conditions.
|Noon water line is dropping|
The mulch is still wet at 4pm. There are probably a few puddles underneath as well.
|4pm only a few puddles and wet mulch|
By the next morning the water had infiltrated into the soil and ground water. Now it can slowly make its way to Easter Lake through the water table.
This site had passed the infiltration test but still had a fair amount of clay in the soil, so I was happy to see it work right out of the gate.
The Easter Lake Watershed Project even shared the great pictures and this story on Facebook
"10 days ago this rain garden was installed within the Easter Lake Watershed. The 160 SF rain garden temporarily ponds stormwater runoff from a 1405 SF rooftop area. By capturing and helping the water naturally soak into the ground, we reduce runoff and drainage issues in the yard and help to improve water quality downstream in Easter Lake! Our estimates show that this garden can help reduce about 27,000 gallons of stormwater runoff each year! We can’t wait to see this pollinator friendly garden grow!"
