He originally built three cottages and a park with fenced-in tame deer in the area near the rail station[5] in the early 1870s.

The railroad's main branch into Washington opened in July 1872, with stations established at Glenn Dale, Seabrook, and Lanham, among others.

Many of its homes were built in the 1950s to serve the needs of new employees at the newly established NASA Goddard Space Flight Center, which is located immediately to the north.

However, Seabrook remains a residential area with numerous single homes surrounded by green lawns shaded by century-old oak trees.

Within the Lanham-Seabrook area, there is only one post office (20706), located a half mile east of Seabrook Station on route 564, which both towns must share.

Prince George's County Police Department District 2 Station in Brock Hall CDP, with a Bowie postal address, serves the community.
