Abstract Permit specifications, construction plans, and field measurements were used to examine the correlation between design and conditions 'as-built' in a population of 11 palustrine emergent marshes created in the metropolitan area of Portland, Oregon between 1980-1986. The projects ranged from six months to almost seven years in age. Data on planned and existing hydrology, wetland area, wetland shape, slopes of banks, and vegetation were collected for each site. Information on the plans for each site was gathered from the section 404 permit files of the Portland District Office of the U.S. Army Corps of Engineers and the permit files of the Oregon Division of State Lands. Results indicated that none of the wetlands studied were designed or constructed as permitted.
