Upper Dublin Township is a township in Montgomery County, Pennsylvania, United States. Until the 1950s, Upper Dublin was mostly farmland and open space, but transitioned to a residential suburb during the postwar population boom. The population went from just over 6,000 residents in the 1950s to just under 20,000 by 1970. Today, Upper Dublin is mostly spread-out development housing, and has the fourth highest median income in Montgomery County.
Upper Dublin has more than 40 sites and 600 acres of parkland and open space ranging in size from neighborhood squares to sprawling meadow-like areas. There are natural resource areas as well as active recreation sites with varying amenities including tennis courts, play lots, jogging/exercise trails, picnic pavilions, playing fields, basketball courts and sand volleyball courts. In 2005, the Township opened MonDaug Bark Park, with wooded trails as well as a 1-acre fenced, off-leash dog park.
The primary center of business and industry in the Township is the Fort Washington Office Park, it contains the offices of over one-hundred different companies, including Aetna, AccuWeather, Eastern National, Genworth Financial, a suburban campus of Temple University, a campus of Gwynedd-Mercy College and a campus of DeVry University. It also contains the corporate headquarters of Johnson & Johnson division McNeil Consumer & Specialty Pharmaceuticals, marketers of over-the-counter and prescription pharmaceuticals including Tylenol (acetaminophen) and Motrin IB (ibuprofen) products. Their building is based on a 110 acre site and has a workforce of 2,600 employees. The office park was also home to the corporate headquarters of CDNOW, the pioneering online music retailer. In recent years, the Fort Washington Office Park has experienced a vacancy rate higher than that of other commercial/industrial parks in the region, due in some part to problems with flooding.
