Orestimba Creek Feasibility Study - Stanislaus County

Economics Appendix – Draft Report - Orestimba Creek Feasibility Study, Stanislaus County, California – September 2012
arrive at the estimated number of employees per business. The business types were matched to
IMPLAN sectors and daily production values per employee were taken from IMPLAN estimates.
Table 12 displays the Employee and Output (2010$) Relationships for Non-Residential
Categories within the 100 year floodplain.

*Affected Employees are based on the structures that are inundated under a 100 year flood
event.
Based on these data and assumptions, the non-residential categories itemized above provided
the basis for estimating the square feet per employee and the daily output per employee for the
Newman Study area floodplain. The conclusions included the displacement of 821 employees
with an average output of $410 per day.
Analysis of the structures within the without project floodplain indicates that the depth of
flooding ranged primarily from .5 to 1.5 feet. Using the FEMA BCA Tool (2009) which
provides the depth-damage function based on the depth of flooding versus the business
interruption, the number of business interruption days were estimated at 30 to 60 days.
Accordingly, business interruption was estimated between $10 and $20 million for a 100-year
event flood. Both the NED and LPP are expected to provide flood risk reduction which is
capable of preventing damages to businesses in Newman, California should a 1% flood event
occur.
