Discovery Bay & Byron

Discovery Bay is based on a waterfront community of 3,500+ homes with private docks with access to the Sacramento-San Joaquin River Delta. Now Discovery Bay has grown and added Discovery Bay West which features gated and non-gated “off-water” communities with homes from 1,400 square feet (130 m2) up to 4,700 square feet (440 m2). As of 2010, its population was 13,352.

In July 2007, Discovery Bay celebrated its maturity into its own community by changing the ZIP code from 94514 (which it shared with the neighboring community of Byron) to 94505. A huge town celebration ensued with a world record-setting paddle boat raft-up.

According to the United States Census Bureau, the CDP has a total area of 7.0 square miles (18.2 km²), of which, 6.2 square miles (16.1 km²) of it is land and 0.8 square miles (2.1 km²) of it (11.7%) is water.


The 2010 United States Census reported that Discovery Bay had a population of 13,352.

As of the census of 2000, there were 8,981 people residing in Discovery Bay.

Schools in Discovery Bay are in the Byron Union School District. There are two K-6 schools in the district: Discovery Bay Elementary in old Discovery Bay and Timber Point Elementary in Discovery Bay West. Excelsior Middle School in Byron is the district’s sole 6-8 school. It was a California Distinguished School in early 2004. High School students (9-12) attend Liberty High School in the Liberty Union High School District located in nearby Brentwood. There are future plans for an as now unnamed Fifth High School on the south side of Highway 4.

Byron Hot Springs
Byron, California is also home to the somewhat well-known and historical Byron Hot Springs, a now-abandoned resort that was a retreat that attracted many movie stars and famous athletes in the early 1900s. The first hotel was built in 1889 and was a three-story wood building, with a few cottages scattered nearby, as well as a laundry, gas plant and ice plant, all of which were destroyed by fire on July 25, 1901. A second hotel, also three stories, but made of stucco was constructed 1901-1902, but it burned on July 18, 1912. The third and final hotel, a four-story brick structure was built in 1913 and still stands.

In 1938 the resort closed, after a series of lawsuits that were probably brought about by the Great Depression, but was leased by the government in 1941 and became a military interrogation camp housing both German and Japanese prisoners of war, known as Camp Tracy, until 1945, when orders were sent to dismantle it. Additional information about its usage during WWII can be found in the book, The History of Camp Tracy: Japanese WWII POWs and the Future of Strategic Interrogation.

In 1947 the Byron Hot Springs property was put up for sale and purchased by the Greek Orthodox Church for a sum of $105,000. It served as the Monastery St. Paul for several years. It then changed hands several times both as a resort, country club and private residence. It is currently privately owned by a developer who hoped to begin restoring the resort in early 2009, but the property is now in a state of disrepair.[5] Plans for the restoration of Byron Hot Springs are outlined at byronhotsprings.com. In 2005, a Victorian-era carriage house on the property was burned to the ground. The hotel itself sustained some fire damage, but still stands.[6]

Byron Hot Springs is located 1.5 miles (2.4 km) south-southeast of Byron.[2] A post office operated at Byron Hot Springs from 1889 to 1930.[2]


Byron Airport
In 1993 Contra Costa County broke ground on a new airport two miles (3 km) south of Byron. On October 8, 1994, Byron Airport was dedicated. The new airport has 1,307 acres (5.29 km2) of land. 814 acres (3.29 km2) are reserved for Habitat Management Land for the San Joaquin Kit Fox, a federally listed endangered species, as well as many other endangered and special status species. The airport is also the home airport of the Patriots Jet Team[7]

There is limited bus service to Byron by Tri-Delta Transit’s route 386, that connects the community and Discovery Bay with the Brentwood Park and Ride Lot where passengers may transfer to buses connecting to other cities in the region in addition to Pittsburg/Bay Point (BART station) and Brentwood Dimes-A-Ride transit.[8]
