Erosion Control With Native Plants

June 13, 2017

Project Description:

Homeowner was having erosion and drainage problems in the backyard of their residential landscape. The eroded slope in the backyard was dug out, regraded, and rebuilt with drain tile to help prevent future erosion. A total of 810 native perennials,   two birch trees, and a maple tree were planted on the slope that will help stabilize   the soil. Lastly, the grass that was damaged from washed out soil was torn out and replaced with 250 square yard of sod.
