the municipality of San Francisco was given the right, by General Kearney acting as governor of California, to sell "water lots" in the tidelands between Clarke's Point and Rincon Point so the city might gain revenues from the sale. At the same time, the owner of the land at the foot of Telegraph Hill, W. S. Clarke built a timbered wharf and the location became known as Clarke's Point. Later, a substantial wharf long and wide was erected to the depth of water, , made the landing available to deep water ships. this project was followed by other wharves built below Broadway and Clay streets, and at Commercial street. When gold was discovered in California, the first hulk of an old iron revenue steamer, the James K. Polk, was beached at the foot of the bluff near Clarke's Point and became the foundation of the first real passenger landing in the city. It was at this site that the population of San Francisco met the Pacific mail liner the Oregon to receive the official announcement that California had been admitted to the Union. The bluff at the point was quickly leveled and on the land created a wharf was built that became the first regular berthing place, for a short time, for the Pacific mail steamships. Whatever products came to California, and whatever California produced, had to be carried by ship. In the first year of the gold rush, hundreds of ships were beached and abandoned in the tidal flats of Yerba Buena Cove, and numerous ships were run aground to become parts of the city itself. In 1853, the Vallejo Street wharf lease was granted, and a larger wharf was built. In the ensuing years, the state legislature passed bills concerning the sale of water lots and authorizing the city to construct wharves beyond its boundary and to set wharfage rates. The battles over control of the waterfront, water lots, and docking privileges began. The great Central Wharf was built in 1849, named for the central wharf in Boston, and was located where Commercial street is now. Eventually a huge forest of masts from a fleet of abandoned vessels filled Yerba Buena Cove. By 1851, the Central Wharf had ten times more business offered than it could handle, and many new wharves were struck into the bay, including those at Market, Sacramento, Washington, California, Clay, Jackson and Pacific Streets.
