Hill Valley (Universe 88)

History
The town of Hill Valley was first settled in 1850 and was incorporated in 1865. Its founder was William "Bill" Hill, whose name would later be forgotten. By 1869, it was connected by railroad to San Francisco via the Central Pacific Railroad Company as part of the Transcontinental Railroad. Marshal James Strickland also arrived in Hill Valley that same year. Construction of a new county courthouse was well underway in 1885, the year a new clock was dedicated for the building. The Shonash Ravine Bridge was completed in the Summer of 1886, around the same time the ravine was renamed the Eastwood Ravine Bridge

The area around the courthouse was developed in the following seventy years and by the 1950s had become the downtown of Hill Valley. A grass-covered town square was built in front of the courthouse, while stores, theaters and cafés opened on the surrounding streets. On Saturday, November 12 1955, at 10:04 p.m. PST, lightning struck the courthouse's clock tower, freezing the clock at 10:04. The clock was never repaired and as it became a landmark of Hill Valley over the years, it was preserved in its non-functional state by the Hill Valley Preservation Society.

By a few decades later, Hill Valley was no longer a town but a city — as confirmed by the greeting sign of 1985. Many of the town square businesses had moved or closed down. The new businesses which replaced them included a second-hand shop and an adult book store. The courthouse fell into a state of disrepair, while at night at least one homeless person slept on the town square park benches. To accommodate the growing need for parking space, the grassy park outside of the courthouse was converted into a parking lot. What happened to everybody's home town is obviously the same thing. They built the mall out in the boonies, and killed all the business downtown, and everything changed.

By the 21st century, the downtown area had experienced a revival as the courthouse was converted into the Courthouse Mall. Businesses began to move back into and around the town square and the parking lot was converted into a pond. The clock on top of the courthouse was still preserved at 10:04 due to the continuous efforts of the Hill Valley Preservation Society.

At some point, the skies above the city turn red, the city is than destroyed by anti-matter during the Anti-Monitor Crisis, the city and the rest of the universe are then rebuilt after the sacrifice of Oliver Queen.
