Best Management Practices for Riprap Shores

  1. Consult a shoreline specialist and/or local soil and water conservation districts staff This link leads to an external site.Aquatic Habitat Restoration Grant Program.
  2. Introduce aggressive native shoreline plants into riprap. Deep-rooted native plants will withstand the erosive forces of moving water, allow for sediment to accumulate which encourages natural vegetation regeneration.
  3. Reduce riprap shorelines on PWA sites.
