We are a collaborative of individuals, organizations, and communities working to address critical water issues throughout New Orleans and the greater region. This work is guided by the vision and principles of the Greater New Orleans Urban Water Plan.
We facilitate the flow of information on emerging water management opportunities and foster effective collaborations among participants. Our focus areas include: demonstration projects, policy, advocacy, education, and outreach.
We also recognize that this region’s long-term sustainability depends upon urban water management efforts working in parallel with coastal protection, restoration, and other measures to address severe weather and sea level rise.
We work to make New Orleans a strong, safe urban environment that celebrates the region’s abundant water resources. Through these efforts, New Orleans can become America’s Water City, leading the nation in urban water management practices, design, technologies, and innovation.
Nathan Lott, Director
Nathan came to New Orleans after a decade in natural resource management in the Mid-Atlantic. As a graduate student at Tulane School of Architecture, he gained a deep appreciation for the region’s unique history as well as the challenges of building in a deltaic environment like Southeast Louisiana. In particular, his work on climate change and cultural heritage built upon a longstanding commitment to the joint protection of natural and cultural resources.
That synergistic approach was a hallmark of his seven years as executive director of the Virginia Conservation Network. A coalition of more than 125 nonprofit and community groups, the network championed energy efficiency benchmarks, conservation easements and watershed restoration. During Nathan’s tenure, the network united rural communities concerned about a proposed uranium mine with business interests downstream to protect the drinking water of more than 1 million people. In partnership with foundations and conservation groups across six states, Nathan helped launch the Choose Clean Water coalition, which became a force for clean-up of the Chesapeake Bay and a resource to local governments.
Previously, Nathan served in a state agency tasked with curbing runoff pollution from farms and cities and with promoting parks and open space. During that time he first encountered many of the principles of green infrastructure. He served as lead author for a greenway-blueway project, Captain John Smith’s Trail on the James River. He also authored a guide book to hiking trails near Richmond, Virginia. Nathan is married to Elizabeth Lott, a minister and Gulf South native. The couple have two school-age children.

Rachelle Sanderson has been passionate about climate change and community-based climate adaptation solutions since her youth. Rachelle's interest led her to receive her Bachelor of Science in Professional Meteorology from Mississippi State University which provided her with knowledge of meteorological and climate systems, as well as skills to engage the community as a broadcaster. From there, she received her Master of Science in Coastal Geomorphology from University of New Orleans, combining climate with coastal land loss in Louisiana. As a temporary resident of Baton Rouge and as an intern at NOAA's local River Forecasting Center, she experienced the flooding of August 2016 from a community and professional perspective. These experiences in combination with her current role as Coastal Community Resilience Program Manager at Foundation for Louisiana have led her to believe that policy, programs, and projects related to climate change impact can be developed in ways that lead to a more just and equitable society if those who are most impacted by climate change are supported to lead the way. We are excited to bring her scientific background and her experience with community organizing to the Water Collaborative as we address flood reduction through community-based solutions at the local level.
