Restore wetlands

Details

Re-establish former wetlands or rehabilitate degraded ones to reduce flooding. Work with relevant agencies and landowners to determine feasibility to implement measure.

Capital Cost

Moderate (implementation) – dependent on project scale

Operations & Maintenance

Moderate – will require monitoring/maintenance

Effectiveness

High – can significantly reduce flooding by increasing available flood storage

Flexibility

Moderate – may require planning and consultation; rehabilitation can be done progressively over time

Barriers to Implementation

Permitting; design/construction knowledge; maintenance approaches/expertise

Equity

Ensure that land restoration does not conflict with other land priorities; ensure that plans mitigate unintended consequences to the extent possible, e.g. creation of mosquito breeding grounds; ensure that site selection is based on greatest need.
