- DUST Marsh Restoration Project
- The East Bay Regional Park District (Park District or EBRPD) proposes to restore the appropriate flow regime within the 55-acre Demonstration Urban Stormwater Treatment Marsh, or DUST Marsh. The DUST Marsh is within Coyote Hills Regional Park, City of Fremont. The DUST Marsh was planned and constructed in the early 1980's by the Association of Bay Area Governments to study the effects and capability of wetlands in treating pollutant loads contained in urban runoff. The Park District now maintains the DUST Marsh. From an approximately five-square mile area of Fremont, urban runoff flows into stormdrains that empy directly into Crandall Creek. Crandall Creek flows into the DUST Marsh. Since the DUST Marsh was built, cattails (Typha spp.) have invaded and have completely taken over a 660-foot long bypass channel. Consequently, cattail and sediment accretion have eliminated open water and have altered the original gradients and flow regime of the channel, creating back-flow conditions.
