Alexander, an African American, graduated from the College of Engineering at the University of Iowa in 1912, where he was also a football player. The bridge over the Tidal Basin and the seawall were completed by the engineering firm of Alexander and Repass out of Iowa in the 1940s. The Tidal Basin was first built in the 1800s. Water from the Tidal Basin is also used (via a pumping system) to maintain water levels in the Lincoln Memorial Reflecting pool. The rush of water out of the Tidal Basin sweeps away any silt or sediment build up inside the Washington Channel, keeping it navigable As the tide turns, water trying to flow out of the inlet gates causes the gates to close, and the outlet gates on the Washington Channel side of the Basin open. Twice a day at high tide, 250 million US gallons of water from the Potomac River enter the Tidal Basin through the inlet gates. Fill lands separate the Washington Channel from the Potomac River the Washington Channel drains into the Anacostia River just above its confluence with the Potomac. It was built to harness the power of the tides in the Potomac River to flush silt and sediment from the Washington Channel. The Tidal Basin is about 107 acres in size and approximately 10 feet deep. It is the location most associated with Washington's Cherry Blossom Festival that takes place each spring. They can all be visited via the Tidal Basin Loop Trail. Memorial, the FDR Memorial, the George Mason Memorial, the John Paul Jones Memorial, the Floral Library, the Japanese Pagoda, and the Japanese Lantern and site of the First Cherry Tree Planting all surround the Tidal Basin.

“They’re really, really interesting structures, and most people don’t even know that they’re there,” Brennan said. The funding for the feasibility study came from the Infrastructure Investment and Jobs Act and the 2022 Disaster Relief Supplemental Appropriations Act.įunctionality aside, one thing that Brennan hopes to preserve when all is said and done are the gates’ artistic elements. Once the team has a cost in mind to present to Congress, Brennan said the next steps would be finalizing and designing the improvements before any actual construction would begin.Īs for why it took so long to address the degrading condition of the flood gates, Brennan said that federal funding on infrastructure has focused on commerce-related projects in recent years, as opposed to smaller ones like the flood gates. But we don’t know the magnitude of the work that’s going to be involved in rehabbing these structures.” “We know that some of have broken, we know that some work. “It’s a situation where we don’t know what we don’t know right now,” Brennan said.

That’s why the federal government awarded the Army Corps $400,000 to do a feasibility study and have a team of engineers determine how to fix the gates and what it would cost.īrennan said visitors to the Tidal Basin should expect to see a barge-mounted crane removing debris around the inlet structure and engineering teams assessing the gates for the next year. While Brennan said that inspections are done every year, he previously hadn’t seen any funding for repairs. “And some of the roller gates are, well, they haven’t been exercised in a long time, meaning they haven’t been open or closed. “Some of the tidal gates are working, some of the hinge pins are completely worn out,” Brennan told WTOP. He said that an inlet flood gate underneath the Ohio Drive Bridge takes in fresh water from the Potomac River during high tide, while the outlet gate underneath a different part of Ohio Drive flushes out old water down the Washington Channel during low tide.īut the machinery involved in that process has suffered from wear and tear.

The purpose of the flood gates is to make sure the water in the man-made reservoir doesn’t become a stagnant pond, according to Kevin Brennan, the chief of navigation for the U.S.
