Regulatory Pathways for Nature-based Solutions

This project is a close collaboration between regulators, project proponents and technical experts. The primary objectives are:

Develop case studies of NBS and/or horizontal levee projects, the key tradeoffs associated with them (habitat, water quality, public access, etc.), and the impacts that regulatory directives have on design and implementation.
Identify permitting challenges for NBS and horizontal levee projects, including initial permitting barriers, regulatory requirements that make projects cost prohibitive and/or high risk for project proponents, and regulatory constraints for long-term operations and maintenance.
Identify potential regulatory and permitting pathways for NBS and horizontal levee projects to address the identified challenges. If current pathways exist, identify recommendations for possible improvements.
Complete an analysis that summarizes key findings and recommendations.
