Damascus is a city in Clackamas County, Oregon, United States. The population was 10,539 residents as of the 2010 census.
According to Oregon Geographic Names, Damascus can date its existence as a community back to 1867, when a post office by that name was established. That post office was closed in 1904. The original heart of the community is along Oregon Route 212, which as of 2004 serves as part of the city's southern boundary.A 2000 decision by Metro to expand Portland's urban growth boundary into the area prompted some citizens of the community to submit Measure 3-138, a measure on the ballot for the 2004 general election in November. The initiative's passage resulted in the incorporation of the former unincorporated communities of Damascus and Carver into the City of Damascus, a step which prevents nearby cities from annexing the community.The city was the first new city in Oregon in 22 years.In a special election on September 21, 2005, a city charter was approved by 88% of its voters. Voters in eleven parcels of land between Damascus and Happy Valley were given the chance to vote on annexation to Damascus: six of the areas voted for annexation, four voted against, and in the eleventh no votes were cast.
