Cheasty Boulevard South is a 1.3miles route along the eastern edge of Seattle, Washington's Beacon Hill neighborhood. It was declared a City of Seattle landmark on January 15, 2003. Designed in 1903 as part of Seattle's Olmsted parks system, the property was acquired in 1910. Originally named Jefferson Boulevard (after Jefferson Park), it was renamed in 1914 after E.C.
