Changes in acreage within a 15 minute flight circle of the two airbases It should not be surprising that the additional escape was in a location with a comparatively large difference in flight time to the fire. The movement of the air base northwest from Hemet-Ryan to March will logically place it closer to some acres and farther from others. To assess overall effectiveness of air suppression, it is necessary to look at the location of all air resource in Southern California as well as areas that historically have had aggressive fires that can escape initial containment. In addition to CDF’s air base in Riverside County, CDF also has an airbase at Ramona in northern San Diego County. The US Forest Service also operates air bases at San Bernardino and Fox Field in Los Angeles County. The following figure labeled ‘Responsibility Acres” shows the fire suppression responsibilities within the 15 minute flight circles of Ramona, Hemet-Ryan, and March air attack bases. A shift from Hemet-Ryan to March would create an ‘arc’ outside the 15 minute circle on the south side at the same time it would add other coverage to the northwest. The following table describes the potential changes in terms of acres within the 15 minute circle and acres within a 16-19 minute range. Coverage within 20 minute response (5 minute takeoff, 15 minute in flight) SRA - State Responsibility Area (acres) LRA - Local Responsibility Area (acres) FRA - Federal Responsibility Area (acres) Same 1,337,723 1,518,981 1,376,315 1-4 minutes closer to March 114,023 284,274 480,915 1-4 minutes closer to Hemet Ryan 376,866 231,522 236,137 Net Difference at March -262,843 52,752 244,778 Percent Difference -14% 3% 12% A shift to March would primarily impact acreage in northern San Diego County that is within 10 minutes of flight time from Ramona Air Attack Base. In addition a review of the potential of large fires in this part of San Diego is not that high compared to other areas within Southern California
