9) Parts (iv) and (v) address documentation that areas are or are not subirrigated and flood irrigable. The Division will assume that Oak Creek is both subirrigated and flood irrigable, unless information to the contrary is submitted. Isolated pockets of subirrigation is noticeable, particularly the willow/red top and the sagebrush shrub communities along the creek. The extents of these communities are delineated on Exhibit 4.6-10, "Oak Creek -Alluvial Valley Floor, Declassification Area, Vegetation Map" and further addressed in Item 11. Evidence of any flooding in or along the Oak Creek occurs during high precipitation events and are mostly concentrated by the existing highway, county road and railroad fills. 10) Part (vi) requires "Analysis of a series of aerial photographs, including color infrared imagery flown at a time of year to show any Tate summer and fall differences between upland and valley floor vegetative growth and of a scale adequate for reconnaissance identification of areas that may be alluvial valley floors." The Division has color infrared aerial photographs of Oak Creek flown in September of 1978. Does P&M have access to more recent color infrared photographs? If so, please provide the required analysis to show the presence or absence of alluvial valley floors on the requested portion of Oak Creek. P&M does not have in its possession, nor have access, to more recent infrared photographs of the Oak Creek valley to correlate seasonal vegetative growth differences between the upland and valley floor areas. 1 i) Please provide a detailed vegetation map (scale of 1" = 100') for the requested area. Existing vegetation growing along the stream and the streambanks categorically belong in one of the vegetation mapping units described in Section 2.4, Vegetation Summary of the approved permit. Exhibits 2.4-1 and 2.4-2 of the approved permit depict the areal extent of each unit. In addition, Exhibit 4.6-11, "Oak Creek - Alluvial Valley Floor, Declassification Area, Vegetation Map" delineates the identified vegetation units along the stream within the proposed declassification area. The units identified consist of
