The State Capitol building burned to the ground in the 1880s and the Vallejo Fire Department requested aid from the Fire Department at Mare Island Naval Shipyard . As there were no bridges at that time , the Mare Island Fire Department had to be ferried across the Napa River , arriving to find only the foundation remaining . This was the first recorded mutual aid response in the state of California .   Some of the first Europeans drawn to the Vallejo area were attracted by the sulfur springs ; in the year 1902 the area was named Blue Rock Springs . It was also known as White Sulfur Springs and that was the name of the road leading to it from town , today shortened to `` Springs Road '' .
