annexation for industrial development in 1999. But the Port of Portland renewed efforts to annex West Hayden Island in 2008 and Portland City Council voted on July 29, 2010, to go forward with an analysis of annexation that would allow for an undetermined port facility and preserve the remaining as a protected natural area. History In 1792, the island was discovered by Lieutenant William Robert Broughton, commander of the Royal Navy survey brig HMS Chatham, who named it Menzies, after the botanist of his ship Archibald Menzies. (He also named Vancouver after his commander George Vancouver at the same time) In 1805, Lewis and Clark named the island Image Canoe Island after a large canoe carved with images of men and animals emerged from the opposite side of the island. Hudson's Bay Company called it Vancouver Island, and in the early 19th century, it was called Shaw Island for Colonel W. Shaw who owned land on the island. In 1851, the island was renamed for the Oregon pioneer and early Vancouver settler Gay Hayden who owned the island after settling there in 1851 upon hearing of the Donation Land Claim Act a year after it was passed. He built a grand home and lived on the island for five years with his wife Mary Jane Hayden and twin children. Development In 2008, the Port of Portland began exploring and planning the annexation and development of West Hayden Island. The planning process, which is slated to end as early as the end of 2012, would conclude with an annexation agreement that would address recreation, mitigation, land management, habitat preservation, security, repair and improvements of local roads and a community enhancement fund. The proposed plan would develop 300 acres for industrial use and leave 500 acres of natural area untouched. The plan was opposed by environmental groups, such as the Audubon Society of Portland. The city of Portland commissioned ECONorthwest to measure the net economic benefits and impacts of the proposed development. The report compared a no-development scenario to the proposed 300-acre development scenario. When accounting for natural resources, recreation, and local and port economic impacts, the report found that the benefits of development were likely to outweigh the benefits of forgoing development. The analysis also found that the benefits of development were likely to outweigh the costs of development. References Neighborhoods in Portland, Oregon Islands of the Columbia River in Oregon
