The Sierra Nevada area was split based on ecosystemdifferences, as well as variation in projected climate impacts. The Bay-Delta is the only region that shares all its counties with otherregions. The designation of the Bay-Delta as a region recognizes that this area is distinct due to its elevation profile and floodvulnerability.5-2 Cambridge Systematics, Inc.
