By the Numbers: 128

The Chesapeake Bay has more than 11,600 miles of shoreline. Evidence of its changing tides can be observed along much of the region, whether it is a high water mark on a dock piling, a line of seaweed on a beach or a shorebird pulling shellfish from the mud of a temporarily exposed flat.

In some watershed cities—like Annapolis, Maryland—the difference between high and low tides is about one foot. In others—like Norfolk, Virginia—this difference can reach up to three feet. We have built our roads, homes and buildings around the regular movement of this water. But as sea levels rise, land subsides and natural barriers to coastal flooding are lost, our coastal cities will face more impactful high-tide flooding that occurs regardless of heavy winds or rain.

Motorists drive through a flooded section of Llewelyn Avenue near the Lafayette River in Norfolk, Virginia. Such high-tide or nuisance flooding occurs regardless of heavy winds or rain.

High-tide flooding has also been called sunny-day, shallow coastal or nuisance flooding. The National Oceanic and Atmospheric Administration (NOAA) records a high-tide flood when one of its local tide gauges measures a water level above the local threshold for minor impacts. While the depth and extent of high-tide floods can vary, the nuisances that result are far from minor: disrupted transportation, degraded stormwater management systems, flooded roads, homes and businesses, and strained maintenance budgets.

Rates of high-tide flooding on all coasts are rising. In a June 2016 report on the state of high-tide nuisance flooding in the United States, NOAA researchers attribute increasing flood frequencies to local sea level rise—which itself is attributed to the melting of ice on land as the air warms and the expansion of seawater as oceans warm—and local land subsidence, or the settling or sinking of land. Indeed, according to the report, “annual flood rates have increased locally by two or three times or more as compared to the rate experienced 20 years ago.”

The National Oceanic and Atmospheric Administration (NOAA) operates four long-term tide gauges in the Chesapeake Bay watershed. In 2015, these tide gauges—located in Annapolis, Baltimore, Norfolk and the District of Columbia—experienced a total of 128 high-tide flood days. This number is expected to decline in 2016.

Of the 28 local long-term tide gauges operated by NOAA, four are in the Chesapeake Bay watershed. Together, these four cities—Annapolis and Baltimore in Maryland, Norfolk in Virginia and the District of Columbia—experienced a total of 128 high-tide flood days in 2015, with Baltimore and Norfolk experiencing local totals just two days and one day below the highest historical record. These floods were likely exacerbated by El Niño, which affected winds and storm tracks along the mid-Atlantic and West coasts.

The 2016 outlook for each of these four cities is lower than the number of flood days the cities observed in 2015: 15 flood days are expected to occur in 2016 in Baltimore, 47 in Annapolis, 33 in Washington, D.C., and 8 in Norfolk. However, NOAA expects future outlooks to underestimate flood days because of the increasingly “nonlinear response” flood frequencies will have to sea level rise. Furthermore, the agency’s high-tide flood outlook does not account for flooding compounded by local rainfall, and precipitation in the watershed is expected to increase in response to climate change.

While we cannot reverse the effects of climate change that have already been observed in the region—which include warming temperatures, rising sea levels and more extreme weather events, as well as coastal flooding, eroding shorelines and changes in the abundance and migration patterns of wildlife—we can enhance our resiliency against them. To build resiliency against high-tide flooding, for example, cities have relied on flood barriers to block rising water, drafted ambitious plans to raise low-lying streets and constructed new facilities higher off the ground.

Through the Chesapeake Bay Watershed Agreement, the Chesapeake Bay Program has committed to increasing the resiliency of the region’s communities, living resources and wildlife habitats to the adverse impacts of changing environmental conditions. Learn about our work to monitor and assess the trends and impacts of climate change and to pursue, design and construct restoration and protection projects that will enhance the resiliency of our ecosystem.

Photo of the Week: Protecting the plumage of the great egret

A great egret (Ardea alba) lands in Kenilworth Marsh in Washington, D.C. Growing to more than three feet tall with a 55-inch wingspan, great egrets are the largest of the three egret species that call the Chesapeake Bay region home.

In the United States, great egret populations are not currently listed as endangered. But in the 19th century, the birds were hunted nearly to extinction for their plumage. In breeding season, long, delicate plumes—called aigrettes—grow from the egret’s back, and these feathers were in high-demand in the fashion world. Experts estimate that at the height of the feather trade, millions of egrets, herons and other birds were killed for their feathers.

In the late 1890s, cousins Harriet Hemenway and Minna Hall began a boycott of the feather trade. The pair formed the Massachusetts Audubon Society, which would eventually grow to become the National Audubon Society—the symbol of which is the great egret. Decades later, the Migratory Bird Treaty Act of 1918 protected migratory birds like the great egret from human activities like hunting and capturing.

Learn more about the great egret, or read how Hemenway and Hall’s work helped protect these and other remarkable birds.

Lafayette River removed from Virginia list of bacteria-impaired waterways

Elizabeth River Project (ERP) staff members Sara Felker, right, and Casey Shaw consult with homeowner Pat Thrasher on a tributary of the Lafayette River in Norfolk, Va., on Oct. 22, 2015. Thrasher joined ERP's River Star Homes program, which helps improve water quality in the Lafayette through the pledges of 3,300 participants.

In June, the Virginia Department of Environmental Quality (DEQ) removed the Lafayette River from its list of rivers contaminated by bacteria. The Lafayette, a branch of the Elizabeth River in Norfolk, Virginia, now meets the state’s water quality standards for recreational use, including swimming, boating and other recreational activities.

Virginia DEQ monitors the state’s rivers, reviewing the data every six years to update its list of impaired waterways. In its most recent water quality report, Virginia DEQ delisted a majority of the Lafayette River—except for a small tributary called Knitting Mill Creek—for bacteria, meaning the river’s levels dropped to those considered safe for recreational activities.

Despite this achievement, the Elizabeth River Project, a local nonprofit dedicated to the restoration of the Elizabeth River, still urges caution when on the water. They advise against recreational contact with the Lafayette within 72 hours of rain, as well as avoiding narrow, shallow areas such as the river’s small creeks. Stormwater runoff can wash disease-causing pathogens into waterways, and the smaller creeks can have higher bacteria numbers since they don’t flush out bacteria as well as larger rivers. They also note that swimmers should always take precautions such as avoiding the water if they have open cuts and showering or washing hands after contact with the water.

The new status of the Lafayette reflects the hard work of local groups and organizations. The City of Norfolk, along with the Hampton Roads Sanitation District, have been working together to upgrade sewer lines to prevent leakages into the river. The city is also restoring seven acres of wetlands along the Lafayette, in addition to 15 acres already restored by local partners. The Elizabeth River Project, in partnership with the City of Norfolk and the Chesapeake Bay Foundation, is working to restore the river’s natural oyster population by constructing over a dozen reefs. Their River Star Homes program, which began in 2011, now has over 3,300 participants who have pledged to take action toward protecting local waterways. "This is a great example of how the efforts of a small organization, the Elizabeth River Project, working with the community and other partners over a sustained period of time, can achieve such incredible results,” noted Chesapeake Bay Program Director Nick DiPasquale. “Hats off to ERP."
