City Parcel Western Boundary

Here is how the EIR describes this aerial photo:

“3/19/86: City area: Agricultural field area completely cleared to open soils, with heavy diagonal till lines, some evidence of standing water north of stables; off-site knoll not disked; activity around stable and arena areas more extensive, with piles of fill (if that is what they were) no longer evident, perhaps having been spread on site.

County area: Vehicle activity and some surface clearing evident in eastern portion of 5 acre parcel, possibly removing a small area of patchy vegetation.”

Initial Rainfall = March 9, 1986
Aerial Photo = March 19, 1986
Consecutive Days of Ponding = 11+
