The next morning, she walks through a neighbor’s backyard to avoid the two-to-three-foot-deep puddle that routinely accumulates on her street after high tides.

For Ms. Peck and her neighbors, it is the only way to live with the encroaching sea.

As sea levels rise, tidal flooding is increasingly disrupting life here and all along the East Coast, a development many climate scientists link to global warming.

But Norfolk is worse off. Situated just west of the mouth of Chesapeake Bay, it is bordered on three sides by water, including several rivers, like the Lafayette, that are actually long tidal streams that feed into the bay and eventually the ocean.
