The downspout for the roof drainage comes down in this NW corner of the building. To lessen the impact of stormwater, a creek bed of large rock was installed. Grassrings2 (our old version 3” ring product) was used on a berm to prevent water from entering the trailer asphalt-surfaced parking lot. Additional product was used beyond the rock area to access the fire hydrant.

Downspout shown on left where roof stormwater enters the rock bed, flows to the right underneath the fence to the corner collection point.
