The Walt Ranch Erosion Control Plan Application (ECPA) #P11-00205-ECPA proposes earhtmoving activities on slopes greater than five percent in connection with the development of 356 net acres of vineyard within 507 gross acres on the approx. 2,300 acre Walt Ranch (Proposed Project). A total of 65 vineyard blocks are proposed. The 507 gross acres include vineyard avenues that would be constructed around each of the proposed vineyards blocks, rock stockpile areas, and access roads that would be constructed or realigned from their existing configuration. Erosion control features that would be installed include: surface and subsurface drainage pipelines, drop inlets, out sloped level spreaders, rock checks, diversion ditches, rock sediment basins, and rolling dips. Up to three new groundwater wells and four new groundwater storage reservoirs would be constructed, along with water distribution pipelines. Deer fencing would surround individual vineyard blocks or clusters of vineyard blocks.
