Section 5 Formulation of Alternative Plans

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

5-58

Water Quality is generally determined by depth. Deeper reservoirs provide less

chance for of reservoir dry-down and possible remobilization of nutrients and

other constituents that have settled into reservoir sediments. Therefore

Alternative 6, because it is deepest, ranks the highest while the “without project”

condition ranks the lowest. Additional information can be found in Appendix E,

Environmental Appendix.

5.4.5.5 Regional Economic Development Account

The Regional Economic Development (RED) account is represented by

Employment created during construction, Employment created after

construction, Agricultural Production and Local Farm Tax Revenues. The

benefits were generated using RIMS II multiplier programs and local tax rolls.

Employment during construction is based on RIMS II output, which is derived

using construction costs. Alternative 6 has the highest construction cost, thus

the greatest regional multiplier effect, while Alternative 1 creates no regional

employment benefits.

Employment after construction is based on O&M costs. Greater O&M efforts

generally require more manpower. Alternative 2 is more costly due to the larger

footprint while Alternative 1 condition carries no O&M cost.

The larger footprint alternatives will take more agricultural land out of

production, while Alternative 1 leaves all lands in production. The lands that are

in production will continue to generate tax revenue. Alternative 1 will remain

the best for both agriculture related components in the RED account. Additional

information can be found in Appendix C, Economic and Social Considerations.

5.4.5.6 OSE Account

The Other Social Effects (OSE) account considers the effects of alternative plans

in areas that are not already contained in the NED and RED accounts. The

categories of effects contained within the OSE account include:

• Urban and community impacts,

• Life, health, and safety factors,

• Displacement,

• Long-term productivity, and

• Energy requirements and energy conservation.

The EAA alternative restoration plans could result in beneficial and adverse

OSE within the study area. The alternative restoration plans could have positive

or adverse OSE impacts on the study area associated with (1) plan
