Q&A: Putting Technology to Work for Water

Get to know Craig Holland, TNC's Senior Director of Investments and leader of a cutting-edge stormwater program called Brightstorm.

Craig Holland explored the rivers of New York and Maine as a child and floated the Colorado River with his computer engineer father. Those influences shaped his understanding of the relationships among people, water and technology—which is the foundation of his role with The Nature Conservancy.

How did your career in conservation begin?
As a young professional with TNC, I contributed to an unprecedented effort to address stormwater issues in Philadelphia with nature-based solutions. That project combined everything I love—fresh water, economics, urban planning and design, landscape architecture, business, politics—essentially, the intersection of people and place.

Explain why stormwater is a problem.
Humans have been altering the landscape since the dawn of civilization, changing the flow and path of water as we build homes, roads, farms and other development. Lack of planning and adequate investments have led to problems, including flooding and water pollution. Runoff picks up oil, trash and chemicals from fertilizers used on lawns and crops, which end up in rivers, lakes and oceans. That runoff becomes stormwater, one of the fastest-growing and largest sources of global water pollution.

Why is it important for TNC to focus on stormwater?
In the U.S., about 90% of urban and suburban land is privately owned. Much of that footprint is controlled by large corporations, many of which have ambitious water quality and sustainability goals. TNC’s collaborative approach to conservation allows us to build trust, which offers the opportunity to guide corporate investments to projects that advance our understanding of how to rapidly improve stormwater management for communities in need.

What are the barriers to progress?
Our human systems are not keeping up with changes in nature. For example, standards for the planning, design and construction of infrastructure are often informed by a national database of historical precipitation patterns—but climate change means history alone isn’t the best predictor of the future. There is demand for innovation, and TNC is helping to fill that gap.

How is TNC supporting innovation?
There are promising technologies from startups that can’t invest in growth unless they know there is a market for their hardware or software. Through Brightstorm, the program I manage, we’re testing the efficacy of new interventions, identifying barriers to adoption—such as permitting—and forging relationships among tech companies, civil engineers and public agencies to speed up improvements. Alongside our work to secure the needed resources, we aim to supercharge progress to benefit communities around the country and the world.

In Florida’s Indian River Lagoon, dolphins and manatees rely on sea grass beds for shelter and food. But development and nitrogen pollution from agriculture are taking a toll on this biologically rich ecosystem. Ponds designed to collect, slow and filter pollutants from stormwater are an important part of the solution to protect the vulnerable ecosystem—but their designs and operations can be improved to produce more benefits, particularly as our climate changes.

That’s why TNC and partners are combining first-of-its-kind technology and continuously monitored sensors in the environment and ponds that trigger outflow valves. These inputs create “smart ponds” that can anticipate how much storage is required at any given moment, for any given forecasted storm event. This allows the ponds to retain runoff longer, which improves water quality. Conversely, their levels can be lowered ahead of storms to provide flood storage. Also, flow rates from smart ponds better mimic natural conditions, reducing erosion and enhancing downstream wildlife habitat.

The goal in the Indian River Lagoon is to create a network of smart ponds that are managed as a system and learn from one another, enabling managers to holistically improve performance over time.
