Document Description
The project includes clearing of vegetation (oak woodland, toyon chaparral and non-native grassland), earthmoving, and installation and maintenance of erosion control measures associated with the development of approximately 19.0 gross acres (15.9 net acres) of new vineyard within five development areas (A-E), including the temporary disturbance of 0.5 acres of grassland for a temporary equipment staging and materials storage area for a total project area of 19.5 acres, located on an approximate 79.3 acre parcel (Figures 1 - 3). Additionally, approximately 3.8 acres of vineyard within Phases 3 and 4 approved by 97061-ECPA (referred to in # P19-00496-ECPA as Development Areas F and G) that has not been converted to vineyard would be developed in conjunction with the proposed project. Combining the development areas in Phase 3 and 4 of #97061-ECPA with the proposed development areas in the proposed project yields a total development area of approximately 23.3 acres. The #P19-00496-ECPA configures the above-referenced development areas as described in Table 1, Proposed New Vineyard Development Summary.
