The Canal Area comprises two neighborhoods of San Rafael, California, designated by the city as the "Canal Waterfront" and the "Canal." The Canal Area is bounded on the east by San Francisco Bay, on the north by the San Rafael Canal and on the south and west by Highways 101 and I-580 and by San Quentin Ridge. Land use is split almost evenly between residential and non-residential (commercial/industrial) uses. The Canal Area provides a substantial portion of the low-income housing in Marin County, one of the most affluent counties in the United States. It is also the location of transportation and waste management facilities serving Marin County and the North Bay.
