Maintaining Grassed Waterways
Metadata[+] Show full item record
Grassed waterways are commonly used as an outlet for water from terraces or to prevent gullies, where water flowing down a hillside concentrates. Inspect grassed waterways annually or after unusually large storms. Perform needed maintenance promptly to prevent costly damage to the waterway. Common maintenance problems with grassed waterways include insufficient grass, weeds and brush, sedimentation, gullies and insufficient capacity.
