Development practices from 1990+ to 2010 have will have altered the regional hydrology, fragmented critical areas of the landscape ecological pattern, and threatened regional extinction of some native fauna. This will increase the public's desire to protect remaining areas of natural vegetation from development. Therefore, Alternative #2, Spread with Conservation 2010, assumes that all remaining areas of high conservation priority and all areas of riparian vegetation, coastal sage scrub, and chaparral, will be conserved beginning in 2010 by purchase or other means. All land outside protected zones and not developed as of 2010 is developed as zoned, to build-out.
Figure 121 shows in dark green the areas that were identified as having conservation priority in 1990+. In light green are areas with some protection. Figure 122 shows the same analysis applied to Spread conditions in 2010. Note the amount of priority habitat that was developed between 1990+ and 2010, thus losing much of its value to biodiversity.
Figure 123, Spread with Conservation 2010, shows the state of the region at build-out following an as aggressive a conservation policy as it will be possible to initiate in 2010.
