Federal Central Valley Project (CVP) via San
Luis Reservoir (pipelines and terminal storage; treatment and
use by Cal-Am |
Unknown. Depends on actions of other agencies
who have right of first refusal. Cost estimates based on 10,000
af. |
Capital costs
about $190 million.
O&M costs
roughly
$1-2 million per year at minimum (see Table
A-13).
|
8-12 years to obtain CVP contract; no action
by PVWMA allowed until 2007.
3-7 years assumed for pipeline and reservoir
storage. |
Reduced impacts of Carmel River diversions.
Pipeline impacts; possible impacts to Delta
fisheries if CVP project component. |
Not reasonably foreseeable due to PVWMA prohibitions,
right of first refusal by other water agencies. |
|
Water from Salinas Basin:
Arroyo Seco concept includes 100,000-af dam,
56-mile lined canal and 15-mile pipeline to the Monterey Peninsula
|
Unknown. Original concept included cost-sharing
among agencies. |
Capital cost of $107 million for dam and canal;
$20 million for pipeline. Costs considered low as no mitigation
measures or Cal-Am facilities included. |
Unknown. Dismissed by County in 1983 and 1991. |
Inundation and streamflow impacts of dam;
canal and pipeline impacts.
Would remove water from Salinas basin, which
already has a serious seawater intrusion problem. |
Not reasonably foreseeable due to County policy
prohibiting out-of-basin water transfers, and existing seawater
intrusion and nitrate problems in the Salinas Basin. |
|
Big Sur/Little Sur Rivers:
Dam/reservoir and pipeline to the Monterey
Peninsula |
Unknown |
Unknown but expected to be very expensive due
to rugged terrain. |
Unknown; 5-15 years for approval based on other
dams |
Dam/reservoir and pipeline impacts to wilderness
area and protected wild rivers. |
Not reasonably foreseeable due to protected river
status, prohibition against out-of-basin transfer. |
|
Carmel Valley watershed (focus on Rancho San
Carlos) |
400 af/yr demonstrated by past studies; maximum
of 3,100 af/yr as recharge. No yield expected as water is not
for sale. |
Minimum of $15,000 per acre-foot based on well
costs alone. $93 million estimated for 3,100-af amount, if available.
Must add purchase price of water, if offered. |
Unknown. Water is not for sale according to Ranch
officials, who are pursuing approved development plans. |
For 3,100-af amount, impact of drilling 900+
wells and extensive pipeline, power and road structure to support
water system. Possible impact on Carmel River surface flows. |
Not reasonably foreseeable due to unwilling seller,
unproven supply over 400 af and questionable viability of water
distribution system. |
|
Purchase water from FORA |
FORA amount is 6,600 af; no yield expected as
water is not for sale. |
Unknown |
Unknown. Water is not for sale as all is needed
for FORA development plans. |
If viable, would offset Carmel River use. Concerns
include extraction and exportation of water from groundwater
basin. |
Not reasonably foreseeable as water is slated
for FORA use, and is not for sale. |
|
Import water from Washington via ocean- going
"water bags" |
Unknown; water rights and technical feasibility
of water bags not established. |
$600- to $1,000-per-acre-foot sale price at Monterey
Bay according to promoter, not including construction of offloading,
treatment, and Cal-Am distribution facilities (several million
dollars). |
Unknown |
If viable, would offset Carmel River use. Effect
of bags and offloading facilities on Marine Sanctuary a concern. |
Not reasonably foreseeable as water rights and
technology not established for West Voast. Considered R&D. |
