imposition - the original course of the creek bent south and entered the Bay near the northern edge of the IKEA property. Temescal Creek near the mouth area is channelized with concrete linings. The mouth of Temescal Creek at the discharge to San Francisco Bay is fully tidal and consists of mudflats and marshland. Historically both banks of Temescal Creek in the lower area of Emeryville were part of the San Francisco Bay tidal floodplain and were extensively filled from about 1900 through the 1970s. Fill included slag, soil and other inert materials originating from the Judson Steel plant. The Judson plant occupied much of the lower reach banks in Emeryville; Judson used this reach for metal recycling/recovery. Foundations remained of a shear, tin baler, scale, and conveyor as late as 1990 when the lower banks were renamed the "Chiron" site and re-developed.
