This area of Calgary was severely damaged by the 2013 flood. I had just finished building the owner of these two properties a new brick patio in the back yard at the end of May. About a year later she contacted me to do something with her front lawns. Her own and the adjacent property. The future of the houses were still very much up in the air so she obviously didn’t want to spend a ton of money yet, but she did want it to look like they were still cared for.
It is a little hard to tell the severity of the the grade change in the before pictures, but the mound that is visible by the truck in the third picture is about the size of the hole in the adjacent lawn. There was next to no topsoil left after the flood and what was there was covered in a layer of river silt.
The machine in the pictures is another contractor doing similar work 2 doors over.
The actual regrading of the two lawns was too much to do by hand totally, so I had a mutual friend of mine and the property owner come with his skid steer and in an hour he did what would have taken a pack of people all day. He left me with a pile of what ever topsoil and plant material he could find mixed as best he could and a regraded sub soil.
I then set to work with my shovel and wheel barrel and spread the organics over the two lawns.
The next July (2015)
The treatment that I employed here consisted of this:
I stripped the topsoil and organics. Remember this was a drastic repair I wouldn’t normally recommend this method. After that I mixed the topsoil and organics and spread over the regraded lawn. To this I added about 2 yards of compost from a local landscape supplier. I then seeded with primarily a sheeps fescue. I had a timed irrigation system that came on twice a day. I believe I seeded 3 times. The next Spring and Summer I fed it with some organic fertilizer and 2 batches of compost tea made from my vermi-compost.
