Summary: Virginia’s coastal marshes are valued at $25,000 per acre per year. These marshes are lost due to development and sea level rise. Thin-layer additions of dredged material to marshes could allow them to reach a desired elevation. The goal is to promote vigorous plant growth. Costs associated with the technology include: dredged material transport, possible remediation of dredged material, engineered reductions in wave impacts, environmental impact studies, and planting of seedlings. The technology also requires public ownership of tidal and subaqueous lands, which is the current Virginia policy.
