Borough of Dormont

April 29th, 2024

The territory in which Dormont Borough is located was held by the Delaware and Shawnee tribes until 1768, when the territory was part of the transaction where Fort Stanwix was purchased from the Six Nations.

In following years, Dormont’s area was part of Cumberland County, Pitt Township in Bedford County, Penn Township in Washington County, and finally, St. Clair Township in Allegheny County in 1788.

Dormont was originally fashioned as a borough from parts of Scott and Union Townships. An order of incorporation was signed on March 31, 1909, making Dormont the first independent municipality in the South Hills of Allegheny County.
The first election of borough officials was held in 1909. Dormont later annexed part of Scott Township in 1909, two additional parts of Union Township in 1913 and 1916, and a portion of Mt. Lebanon Township in January of 1921, giving it a total area of just less than one square mile.

With the construction of the streetcar tunnel and the Liberty Tunnels, came rapid development and a great increase in population. Through the years, the convenience of the borough, plus the amenities offered its residents, has kept it densely populated.

Dormont residents enjoy a large swimming pool, (one of the largest of its size in PA – the size of a football field!), two parks, basketball and tennis courts, Little League field, library, children’s playground, and many seasonal activities for both children and adults. Dormont’s school system, a jointure with the boroughs of Castle Shannon and Green Tree, is comprised of Dormont Elementary School, Keystone Oaks Middle School, and Keystone Oaks High School.

The renovation of the former Hillsdale School building into a municipal center expanded the borough’s administrative offices and the police department’s facilities, with a new fire station built right across the street. Both the police and the volunteer firemen are trained in the latest policies, programs, and procedures to provide a consistently high level of protection for Dormont residents and businesses.

In 1999, the Dormont Historical Society was organized to preserve the memories and memorabilia of the Dormont area. In a very short time, the need for a permanent base became apparent. Borough Council saw the value of the work being done by the Society and allocated it a room in the new municipal center.

The residents of Allegheny County’s Dormont Borough take pride and interest in their community. With a variety of historical sites, combined with new businesses and year-round events, Dormont continues to live up to their nickname, “a mountain of gold”.
