The adaptation strategies below offer possible ways to address anticipated climate risks to freshwater estuaries.
- Design estuaries with dynamic boundaries and buffers.
- Replicate habitat types in multiple areas to spread risks associated with climate change.
- Create permitting rules that constrain locations for landfills, hazardous waste dumps, mine tailings and toxic chemical facilities in areas near estuaries and waterways that flow into estuaries.
- Integrate bank and shore management into land-use planning to prevent activities that can cause erosion and drainage from entering estuaries.
- Implement a land acquisition program to purchase banks and shoreland that are damaged or prone to damage and use it for conservation.
- Implement land exchange programs where owners exchange property in the floodplain for county-owned land outside of the floodplain to implement conservation on those areas and prevent potential negative impacts from entering the estuaries.
- Manage realignment and deliberately realign engineering structures affecting rivers and estuaries.
- Stabilize dunes that help prevent erosion along lakeshores by planting dune grasses and building sand fencing to induce settling of wind-blown sands that flow into estuaries.
- Preserve or restore wetlands to help filter out pollutants and excess nutrients before they enter the estuary.
- Increase shoreland setbacks to provide a stretch of undeveloped land along river banks and lakeshores to prevent erosion and preserve water quality.
- Plant submerged aquatic vegetation (such as seagrasses) to stabilize banks and reduce erosion.
- Restrict or prohibit development in erosion zones.
The adaptation strategies provided are intended to inform and assist communities in identifying potential alternatives. They are illustrative and are presented to help communities consider possible ways to address current and future climate threats. Read the full disclaimer.
