Green Infrastructure

Typically bioslopes are indistinguishable from surrounding areas, so it is recommended that the BMP be staked with markers. If markers are used, they should be placed at both ends at the toe of the slope and every 50 feet.

Routine maintenance should be performed on bioslopes. Generally, this consists of removing debris and trash that could cause clogging, mowing and removing grass clippings.

In addition to routine maintenance, bioslopes require seasonal and intermittent maintenance. For example, in case of snow, ensure that snow does not pile up in the bioslope. Check to make sure that materials used to de-ice the surrounding areas stay out of the practice to avoid clogging and further pollution.

After a large rainstorm, keep drainage paths, both to and from the area, clean to promote sheet flow and allow stormwater runoff to be routed in the intended direction.

If the bioretention area is not draining properly, check for clogging in the underdrain and inlet and outlet structures.

Here are some of the common problems to be aware of when maintaining a bioretention area. They include, but are not limited to, the following:

Should the bioslope become a breeding ground for mosquitoes, the problem is likely with the soil media or the overflow structure.
