The Bay Terraces/Lower Santa Clara Valley ecoregion is an urbanized area on alluvial plains that wrap around San Francisco Bay between the East Bay Hills ecoregion (6r) on the east and the Leeward Hills ecoregion (6x) to the west. Ecoregion 6t also includes the urbanized area around San Jose and the lower Santa Clara Valley. Soil temperature regimes are mostly thermic, with some isomesic. Soil moisture regimes are xeric with some aquic. Common vegetation historically included coast live oak, California oatgrass, and needlegrass grasslands, although land use now is nearly all urban and residential. All but the larger streams are dry through most of the summer.
