Sewickley Heights is a borough in Allegheny County, Pennsylvania, United States. The population was 857 at the 2020 census. ^[4] It is a residential suburb of the Pittsburgh metropolitan area. Sewickley Heights is one of the wealthiest municipalities in Pennsylvania and in the United States. ^[5]

History

Sewickley Heights was established as a borough in 1935, but the area's character was largely established with the move of the Allegheny Country Club from Pittsburgh to its Sewickley Heights location in 1902. The establishment of the country club accelerated the settlement of the area as a haven for wealthy Pittsburgh residents. Many estates established in Sewickley Heights up through the 1930s occupied hundreds of acres with houses of immense proportions. Among the grandest estates was As You Like It, the estate of banker, shipper and investor William Thaw. As You Like It was featured in a 1903 print advertisement of the United States Battery Company that promoted electric lighting for country homes. Other notable estates included the Henry Robinson Rea mansion, Farmhill (which hosted Madame Curie in May 1921), ^[6] and B. F. Jones' 100-room mansion, Fairacres.

Many of the grand estates in Sewickley Heights began to fall into disrepair in the 1950s and 1960s. Many of the original massive houses were demolished and the lots subdivided. Sewickley Heights preserved the country character of the borough by requiring minimum lot sizes of 5 acres (20,000 m²), though many homes are on substantially larger parcels. Many "neighborhoods" of Sewickley Heights are named after the original estate and the clusters of homes on the estate parcel are marked by unique stone fences original to the old estate.

In the 1960s and 1970s, several parcels of land were donated or purchased to form the Sewickley Heights Borough Park. The park now occupies approximately 600 acres (2.4 km²) and is renowned regionally for its hiking and horse-riding trails and other recreation areas. Sewickley Heights is also home to the Fern Hollow Nature Center and the Sewickley Heights History Center, which are co-located on a 33-acre (130,000 m²) site.

Government and politics

Sewickley Heights is a reliably Republican jurisdiction in presidential elections. In every presidential election since 1932 (with the exception of 1992), the GOP has carried the borough. From 1944 to 1988, every Republican nominee for president exceeded 70% of the vote in the borough, with nine of their 12 campaigns breaking 80% of the vote, in spite of only Dwight D. Eisenhower in 1956 and Richard M. Nixon in 1972 actually winning Allegheny County, and multiple candidates in that span losing Pennsylvania.

The best showing for a Republican is the 89.72% of the vote won by Thomas E. Dewey in 1948.

The borough has been somewhat less Republican in the 21st century, however. Donald Trump carried the borough twice, but by less than 20 points both times, with the best showing by a Democrat for president being the 45.47% of the vote won by Joe Biden in 2020.

In the 1912 presidential election, in addition to the totals listed for the Bull Moose Party, Republican and Democratic nominees, Socialist nominee Eugene V. Debs received eight votes and Prohibition nominee Eugene Chafin got five. ^[13]

Sewickley Heights also supported the Republican in at least 15 of the last 17 gubernatorial elections, including Raymond Broderick in 1970, Scott Wagner in 2018, and Barbara Hafer in 1990, in spite of Broderick losing Allegheny County by 24 points, Wagner by 36, and Hafer by a margin of nearly 44 points. Hafer also lost the election statewide by a margin of nearly 34 points. ^{[14] [15]}
