Though Dewalt was noted on highway signs as late as 2013, there are few surviving structures and locations from the original community.

In 2006, the Dew Plantation's house was moved from DeWalt to nearby Kitty Hollow Park to preserve it as a museum.

Lake Olympia Parkway crosses southeast-flowing Oyster Creek by a bridge about 0.1 miles (0.2 km) east of SH 6.

The private, gated DeWalt Cemetery is located 1.8 miles (2.9 km) east within a neighborhood near Lake Olympia Parkway.

The DeWalt Heritage Society was formed as part of the Fort Bend County Museum Association to oversee preservation.
