<br />111e ratio of annual benefits to annual costs is $9.353,000
<br />to $5,568,000 or 1.68 to 1.
<br />
<br />Comparing the annual benefits derived from the separate
<br />
<br />project purpos esl"J the share of total cost allocated to these
<br />
<br />purposes the following ratios of benefit to cost are shown;

<br />Cost allocation
<br />
<br />The total estimated construction cost of the proposed
<br />
<br />project. and the estimated annual operation, maintenance and
<br />replacement expellse have been allocated to the principle pur-
<br />poses served by the project. The cost assigned to each pUIpose
<br />
<br />was found by adding to the specific cost of single purpose
<br />
<br />facilities an allooated share of the cost of facilities used
<br />
<br />jointly for several purposes.
<br />The costs and annual expense allocated to the several
<br />
<br />purpOlles is as follows;
