RIP RAP (ROCK) PROGRAM

RipRapExampleThe City is not currently accepting applications for rip rap.

Rip rap
is commonly used to protect soil from erosion in areas of concentrated runoff. Placing rip rap along a ditch or channel increases surface roughness and slows the velocity of water, protecting the soil surface against erosion and scour.

The City of Duluth established a Rip Rap Program to assist property owners in maintaining drainage easements on their property. Under the Rip Rap Program, the City's Stormwater Utility will provide a single load (approximately 15-18 tons) of Type III rip rap delivered to a single property for the erosion protection of a drainage easement. An HOA is eligible for up to ten loads of rip rap delivered to a single common location. Type III rip rap stone is generally the size of a football up to the size of a basketball.

The City is not currently accepting applications for rip rap.
