*a Net present value of Cal-Am revenue requirements
to fund all capital and O&M costs through 90 years of project
operation, assuming financing and ownership by Cal-Am. Future
annual costs were brought to 1998 levels using a 5% discount
rate.
*b
Projected average monthly surcharge on Cal-Am bill during the
first 30 years once project operation begins (years 2006-2035).
Assumes average monthly use of 8 units of water (800 cubic feet
or 5,984 gallons).
*c
Desalination projects assume a plant located at the Marina site.
Estimated capital costs at the Moss Landing site range from 35%
to 37% higher. Estimated O&M costs are similar for the two
sites.
*d
Costs for alternative options do not include environmental mitigations
(which could be costly for desalination and dredging). Costs
do not include O&M costs associated with Cal-Am system improvements.
