The Origin Story
Before founding Agua Arc, Tiffany Ledesma spent more than 25 years providing direct, on-the-ground strategic communications, public engagement, and partnership services to government agencies, nonprofit organizations, and community partners on topics such as green stormwater infrastructure (nature-based solutions), flooding, and drinking water. She supported the Philadelphia Water Department (PWD) for nearly two decades as part of CDM Smith, helping advance the City's flagship Green City, Clean Waters program. She led public-facing campaigns and innovative programs to increase understanding, educate communities, and empower participation in solutions.Tiffany also supported the Federal Emergency Management Agency's (FEMA) work to reduce natural hazard risks and strengthen climate resilience, supporting projects in various states and Puerto Rico while with Ogilvy's Resilience Action Partners and CDM Smith, respectively.Earlier in her career, she held roles at the Academy of Natural Sciences and the U.S. Environmental Protection Agency (EPA) Office of Water.Born and raised in Puerto Rico, Tiffany developed a lifelong connection to water and nature in the island's coastal and green spaces. As a graduate student, she worked with Puerto Rico’s Department of Natural Resources and Environment on a coastal management plan and began to SCUBA dive to support this effort. These early experiences furthered her appreciation for water, ecological communities, the human communities along the coast, and the vast network of upstream communities that influence the health of downstream waters. That early grounding in coastal and island ecosystems continues to shape her interest in supporting conservation and resilience work.Throughout her career, Tiffany has always focused on the human side of water and environmental work - building partnerships, creating incentives for public participation, integrating arts and culture to engage people, piloting demonstration projects that prove new approaches can be brought to scale, and reimagining traditional communications to help create solutions and meaningful impact for diverse communities and clients.
The Meaning Behind the Name
Tiffany's journey inspired the creation of Agua Arc. The name reflects her roots and mission. Agua represents her upbringing and foundational experiences in public service. Arc symbolizes her role as a bridge.

Testimonials
“Tiffany brings a scalable, innovative model of public engagement from which cities and water programs nationwide can deeply benefit. Having tracked her career since her early days with Philadelphia Water, it’s a privilege to now have her advising The Water Center as a partner. Tiffany is a true delight to work with, seamlessly transitioning from shaping high-level communication strategies to helping us operationalize our programs. From facilitating critical partner connections and sharing industry insights to advising on implementation and evaluating progress, she excels at both the big picture and the day-to-day execution. She is strategic, dependable, and an asset to the Water Center." Howard Neukrug, Executive Director, The Water Center - University of Pennsylvania
"I’ve worked with Tiffany for more than a decade on implementing equitable public engagement programs and campaigns around water, green infrastructure, climate change, flooding, and resilience. She is an expert communicator and has a gift for engaging diverse stakeholders in creative ways. As a consultant to FEMA, we worked closely together on a Federal-State Equity Working Group that brought unique perspectives on implementing mitigation and adaptation programs to underserved communities. As a consultant to the Philadelphia Water Department, Tiffany created a legacy public engagement process to implement the country’s largest green infrastructure program." Hailey Stern, Mitigation Operations Supervisor - Partnerships, Outreach & Communications, Federal Emergency Management Agency (FEMA), Region 3
“For more than two decades at the Philadelphia Water Department (PWD), I was fortunate to have Tiffany as my partner in shaping the department’s public engagement work. Together, we built and led regional watershed partnerships grounded in PWD’s integrated watershed management plans and strengthened by river conservation planning. These collaborations became the foundation for launching the comprehensive communications strategy behind Green City, Clean Waters (GCCW). As Public Engagement Manager, Tiffany oversaw all education and outreach for GCCW, guiding a dedicated team responsible for community meetings, workshops, tours, mailings, social media, surveys, and more. Her leadership ensured that residents understood - and supported - the rollout of green stormwater infrastructure across the city. A hallmark of her approach was using arts and culture to reach audiences who might not otherwise connect with stormwater issues. Initiatives like the Philly Water Bar, Mural Arts paint days, GCCW signage, and milestone celebrations such as the 5‑Year and 1,000 Green Acre events drew in broad, diverse public participation. The resulting engagement model became a national example of how to build authentic community support for large‑scale environmental programs. Tiffany brings creativity, passion, and kindness to everything she does - a combination that makes genuine public engagement not only possible, but powerful.” Joanne Dahme, Founder and President, Mayfly Communications + Former Deputy Commissioner of Communications & Engagement, Philadelphia Water Department

Tiffany brings a unique and valuable talent to public engagement, which is critical and in short supply for complex engineering programs.
