OCEAN AND GROUNDWATER: Groundwater basins in San Fernando, San Gabriel and
Los Angeles overlap lines drawn five and ten miles from ocean desalinated water.
Contamination of basin waters further limits these areas.
SLOPE: Plains and low slopes are best for underground housing, water pumping, rail,
bike and foot travel.

SOIL: Lowlands are most fertile and irrigable.
WINTER SUN: Southern slopes and plains are swept in a low arc.
Solar heat and electricity can be collected in these places.
COMPOSITE: Three areas most suitable for redevelopment are shaded.
