Analysis of the geographical information available for this site shows that it is located below a steep slope; it is adjacent to floodplain, floodway, and liquefaction zones; and there are no street trees in the vicinity. A former oxbow is shown to the north, drawn from pre-settlement maps. At one time, the oxbow depicted in this data was probably a meander flowing through the site and connecting to a wider channel.
