In this session, strategies to make nature-based solutions successful, as well as several initiatives and projects, will be highlighted. An approach to offsetting water quality impacts associated with interstate highway improvements across Tampa Bay will be highlighted. Tampa Bay is impaired for nitrogen and plagued by poor tidal circulation and flushing associated with a causeway built across the bay in the 1930s. Rather than typical ponds or linear water quality features, a new cut through the causeway to improve tidal circulation was studied, modeled, permitted, constructed, and monitored for two years post-construction. A first-of-its kind water quality bank was established for highway projects. An internal client audit indicated the approach saved $100M over traditional approaches and has resulted in larger than expected improvement in water quality, ecological uplift and habitat improvement that does not occur with linear approaches to water quality. The project has spurred a statewide guidance manual to nature-based solutions and similar projects elsewhere.
