<br />1 No Action is assumed to be the FEIS recommended plan.
<br />2 Lateral systems under the East End Government Highline Canal and
<br />the Price Ditch would be expanded due to realignment if the Price Ditch
<br />were abandoned.
<br />3 Price Ditch is lined and Stubb Ditch is placed in pipe.
<br />4 Total annual costs for each alternative, are a sum of the preceding
<br />annual costs minus the no action annual costs.
<br />5 This value is dependent upon the amount of existing improvements
<br />that would be replaced upon failure, the current condition and the expected
<br />life of the existing improvements.
