Economics Appendix – Draft Report - Orestimba Creek Feasibility Study, Stanislaus County, California – September 2012 The producer must manage plant and animal materials to maintain or improve soil organic matter content in a manner that does not contribute to contamination of crops, soil, or water by plant nutrients, pathogenic organisms, heavy metals, or residues of prohibited substances. Animal and plant materials include: (1) Raw animal manure, which must be composted unless it is: (i) Applied to land used for a crop not intended for human consumption; (ii) Incorporated into the soil not less than 120 days prior to the harvest of a product whose edible portion has direct contact with the soil surface or soil particles; or (iii) Incorporated into the soil not less than 90 days prior to the harvest of a product whose edible portion does not have direct contact with the soil surface or soil particles; For purposes of this analysis, any flooding of truck crop acreage will result in the assumption that the vegetables are not fit for human consumption and valued as a total loss. It is deemed to be inappropriate to assume any salvage of vegetable matter for human consumption considering the risks associated with these deadly bacteria. Planting of lands that have previously been flooded are not expected to be adversely affected since the organic materials are assumed to be incorporated into the soil well in advance of the time constraints currently provided by national guidelines. Agricultural Inventory The study area contains approximately 18,400 acres of agricultural lands that are subject to flooding. About 3,400 acres of the affected floodplain is devoted to high value orchard production; about 8,500 acres are planted with tomatoes used for processing, broccoli, and beans in addition to other crop types; the remaining acreage is devoted primarily to field crops such as pasture and alfalfa hay. These agricultural products have been consolidated into five different farm budget analyses. In addition to the damages revealed through farm budget analysis, damages to cropland and associated restoration costs have been included in the analysis. Note in tables throughout the Agricultural Attachment, a flood frequency refers to the annual chance of a flood event. For example, “100” means a 1% (1/100) annual chance exceedance (ACE) event. 60

It is provided to illustrate the cultural practices and cost considerations that are in a typical farm budget analysis process. These farm budgets secured from the UC Davis Crop Budget website are the basis used in the computation of the direct production costs that are used for the agricultural economic evaluation. Totals do not necessarily add due to rounding of monthly data 61
