XII - ECONO~iIC STUDIES

..

12-01. Eeonomie studies. ~ The economic studies prepared for the
preliminary reconnaissance report eonsisted principally of a review of
the flood damage survey submitted by the eity of Trinidad. Economic
studies, including a field investigation of the are~ subject to flood-
ing, were made in eonnection with preparation of this project rep~rt
in order to determine, (a) the economic conditions in the flood plain,
(b) the flood damages experienced, (c) the monetary benefits that would
be creditable to the project, and (d) the ratio of project benefits
to project costs. An area of about 40 aeres in the northwestern and
central sections of the eity, having a property valuation of $1,860,000,
would be proteeted. From these studies it was determined that the ratio
of benefits to costs for the Pinon Canon Dam project would be 1.29:1.
Details of the economic studies are given in appendix III.
