Abstract	The Wetted Drainage Class and Hydrologic Soil Group maps are based on soil classifications that approximate saturation frequency and duration and also estimate runoff potential. The Sump Capacity Data by Quarter Section map is based on sump infiltration data collected and compiled by the City of Portland. "Drainage class (natural)" refers to the frequency and duration of wet periods under conditions similar to those under which the soil formed. Alterations of the water regime by human activities, either through drainage or irrigation, are not a consideration unless they have significantly changed the morphology of the soil. Seven classes of natural soil drainage are recognized-excessively drained, somewhat excessively drained, well drained, moderately well drained, somewhat poorly drained, poorly drained, and very poorly drained. These classes are defined in the Soil Survey of Multnomah County, Oregon; 1983.
Purpose	Mapping and analysis of characteristics related to soil and drainage in the Portland area.
