The action keeps excess runoff water out of concentrated livestock areas. The degree of impact depends on the portion of 

contamination associated with the roof runoff.

The action collects and disposes of runoff which could transport nutrients to groundwater.

The action diverts water from barnyard and feedlot areas, where it could pick up salts from manure.

Not Applicable

Roof runoff diverted away from manure areas. Degree of impact depends on the portion of contamination associated with the roof 

runoff.

Not Applicable

Water collected And conveyed to surface outlet will have limited opportunity to infiltrate.

Not Applicable

Not Applicable

Collected water can be used to increase available water for other uses.

Drier soils in high traffic areas around buildings may decrease compaction potential.

Not Applicable

Where practice is used to increase infiltration, the percolating water has the potential to remove contaminants from the soil profile.

Water collected And conveyed to surface outlet will have limited opportunity to infiltrate.

Collecting and conveying roof runoff away from buildings to an outlet will tend to reduce opportunity for infiltration at the site.

Structures that collect, control, and transport precipitation from roofs.

Not Applicable

Roof runoff is collected and conveyed to a safe outlet.

Water from roof is delivered to stable outlet, minimizing surface erosion.

Not Applicable

Heavy metals are rarely associated with manure. Roof runoff is diverted away from manure areas.
