The 2009 Top Ten Endangered Sites



A designated-National Register Historic property built in 1735, Belmont was purchased in 2004 by Howard County Community College. Plans call for significant new construction—threatening its historic character and the preservation easements that until now have retained the area’s lush landscape.

Clover Hill


This late 1700s home in Rockburn Park has been stabilized, but the search for a public or private curator to establish an adaptive use of the building continues to be unsuccessful.

Doughoregan Manor


The home of Charles Carroll, a signer of the Declaration of Independence, is a national treasure threatened by development. A potential deal with Erikson retirement community has fallen through leaving the Carrolls limited options to secure the funding needed to maintain this National Landmark.

Ellicott City Jail


This building in the heart of the city’s designated downtown historic district has great potential to be adapted for a public building or private business, but is now crumbling from years of neglect and sporadic use.

Forest Diner


New to the list this year, this beloved landmark in Ellicott City on Route 40 is in the path of development and will be razed unless relocated. Traditionally, diners were structures built offsite and located along major byways to serve factory shift workers or travelers with counter service. The Forest Diner is a real piece of Americana, and few are left.

Highland Crossroads


This community at Routes 108 and 216 was established in 1759 but its integrity is threatened by commercial re-zoning and in-fill construction of new homes. Highland residents have fought tirelessly against new zoning and development threats, but the loss of this historic crossroads is imminent.

Mooney’s Cabin


One of the few remaining log structures in Howard County, this historic log building from the 1800s sits near Dorsey Mill Road and requires stabilization, preservation and possible relocation.

Historic National Road


Unregulated development, such as the inappropriately designed Miller Branch Library, is risking the historic integrity of this designated National Road Scenic Byway, which was built in the early 1800s as the first federally planned and funded highway in the country. Today, this historic road, which started in Cumberland, Maryland, and connected the port of Baltimore with the Northwest Territories, is known in Howard County as Route 144. “The new library will be a looming post modern structure — completely out of place along what used to be the wagon trail that pioneers traveled during the great westward expansion,” PHC President Mary Catherine Cochran said. "Howard County needs to enact design guidelines that protect the historic context of this scenic byway."

Rouse Company Headquarters Building


General Growth’s plans for the redevelopment of the Columbia Town Center leave a questionable fate for the Rouse Company building and the Exhibit Center — both important early works of world-renowned architect, Frank Gehry. An economic downturn and GGP's fiscal struggles are further reasons to keep a close watch on the future of this cultural landmark.

US Post Office, Ellicott City


If this 1940s-era building is acquired by local government or another owner, the two murals painted by Peter Paul DeAnna in 1942 inside the building could receive need restoration. Continued funding is needed to restore this building and adapt it for a future contributing use to the Main Street corridor.
