If groundwater extraction continues and/or increases in the center of
[Los Osos], the threat of sea-water intrusion will continue, due to the
large pumping trough. [T]here will be a need to disperse the location

lost to the Basin unless some way can be found to recover it. It will

In coastal aquifers containing both freshwater and seawater, the two
tend not to mix. Seawater is denser, and it tends to underlie the
freshwater and extend inland as a “toe” or “wedge” near the bottom of
the basin. Freshwater is less dense and tends to float on top of the
seawater, flowing seaward and then rising as seepage through the
ocean floor. Although some mixing does occur, the interface between
the two types of water is commonly distinct, so that it constitutes a
boundary to the flow of fresh ground water. In a complexly layered
aquifer system like the Los Osos Valley ground-water basin, the
interface can be at different locations in different layers, depending on
their relative hydraulic connection to pumping wells and the ocean or
bay.

CHAPTER 5: DESCRIPTION OF THE BASIN
Because seawater is 2.5 percent denser than freshwater, the
potentiometric head on the freshwater side of the interface must be 2.5
percent greater than the depth of the interface below sea level, if the
interface is to remain stationary. For example, in order to balance the
interface in an unconfined aquifer at a depth of 400 feet below sea
level, a freshwater head of 10 feet above sea level would be needed. In
this steady-state situation, the seawater remains stationary while
freshwater flows seaward above the interface at a constant rate.
Seawater intrudes when the freshwater head is insufficient to
counterbalance the greater density of seawater, even when the
freshwater head is above sea level.50

The Monitoring Program shall be designed to quantitatively and
qualitatively assess the effectiveness of the Los Osos Basin Recycled
Water Management Plan over time to ensure its objectives are
achieved, and shall include: a baseline physical and ecological
assessment of ground and surface water and related resources to be
monitored; measurable goals and interim and long-term success
criteria for those resources, including at a minimum clear criteria that
demonstrate that the health and sustainability of Plan area resources
are steadily improving over time, including with respect to seawater
intrusion; monitoring provisions, including identification of
appropriate representative resource monitoring locations and data
types (e.g., groundwater levels and quality; wetland, stream, creek,
riparian, and marsh plant and animal abundance, hydrology, and

water quality; etc.) and a schedule for proposed monitoring activities.
The Monitoring Program shall also include measures to clearly
document the manner in which recycled water is being reused and
water is being conserved pursuant to the Recycled Water Reuse and
Water Conservation Programs. ͸ͳ

Within one year of adoption of a due diligence resolution by the Board
of Supervisors, electing to proceed with a wastewater project, a water
conservation program shall be developed by the applicant in
consultation with the local water purveyors within the prohibition
zone for the community of Los Osos, that meets the goal of 50 gallons
per day / per person for indoor use. The applicant shall provide 5
(five) million dollars of funding towards a water conservation
program for indoor water conservation. Incentives shall be provided to
homeowners and other property owners who install conservation
measures within the first year.

Water Conservation Program. The Water Conservation Program
required by the County project, which limits indoor water use to no
more than 50 gallons per person per day on average within the Basin,
shall be incorporated into the Recycled Water Management Plan. The
Program shall be designed to help Basin residents to reduce their
potable water use as much as possible through measures including but
not limited to retrofit and installation of low water use fixtures, and
grey water systems. The Program shall include enforceable
mechanisms designed to achieve its identified goals, including the 50
gallons per person per day target, and shall include provisions for use
of the $5 million committed by the Permittee to initiate water
conservation measures pursuant to the Basin Plan as soon as possible
following CDP approval. The Permittee shall coordinate with water
purveyors to the maximum extent feasible to integrate this
conservation program with purveyor implemented outdoor water use
reduction measures.

Water use efficiency is a policy goal that can be facilitated by economic
incentives.ͺ͵
Utility and system managers as well as regulators and governing
boards should ensure that the price of water services fairly charges
ratepayers or customers the total cost of meeting service and
sustainable water infrastructure requirements, subject to concerns
about affordability. Funding for water utilities should generally rely
on cost-based rates and charges, and these revenues should not be
diverted to unrelated purposes. Full-cost pricing is a sound business
practice that is helpful in obtaining debt financing. The resulting price
signal to consumers is also good practice from the perspective of
promoting wise water use. Where it is necessary to undertake actions
to avoid, mitigate and compensate for environmental impacts, these
additional out-of-pocket costs should be considered in the full cost of
providing service.ͺͶ
When water is not properly priced, it is frequently wasted. In all urban
uses, pricing water at appropriate levels encourages conservation and

Efficient irrigation involves two things: proper design and proper
landscape maintenance. Proper landscape maintenance requires that
the homeowner be informed and diligent – difficult things for an
agency to predict, control, or monitor. For example, planting a waterefficient landscape or installing a sophisticated irrigation system will
not save water if the homeowner fails to match the irrigation schedule
with plant needs. And a manual irrigation system on a traditional
landscape can be efficient if it is properly maintained and used. In
contrast, projecting the savings from an efficient toilet or showerhead
program is relatively straightforward. When an agency decides
whether to invest in a retrofit program, they can reliably calculate
savings from switching their existing stock to ULFTs and from that
determine the costs and benefits of such a program. A similar
evaluation of landscape programs is more difficult and is constrained
by lack of data and consistency.
Farmers and, increasingly, large-lot landscape managers have been
taking advantage of tools such as improved irrigation technologies,
rebates, audits, and weather station data in planning and designing
irrigation systems and schedules. While these tools are often available
in the residential sector, homeowners are less likely to have the time,
inclination, incentive, or expertise to adopt them. One challenge thus
lies in educating, motivating, and in some cases requiring residential
homeowners and managers of smaller residential lots to adopt proper
irrigation scheduling and techniques.ͳͲ͵

To evaluate and develop a wastewater treatment system for Los Osos,
in cooperation with the community water purveyors, to solve the Level
III water resource shortage and groundwater pollution, in an
environmentally sustainable and cost effective manner, while
respecting community preferences and promoting participatory
government, and addressing individual affordability challenges to the
greatest extent possible.

Results indicated that if wastewater is centrally treated and recharged
to the ground-water basin, the entire projected municipal water
demand can be met with locally pumped ground water without
inducing seawater intrusion, even during droughts lasting 1 to 3 years.
If wastewater is exported from the basin, however, large amounts of
seawater intrusion are likely to occur even if nearly half of the
municipal water demand is met with imported water.130

BASIN PLAN FOR THE LOS OSOS GROUNDWATER BASIN
Total agricultural re-use shall not be less than 10% of the total treated
effluent. Disposal shall be prioritized to reduce seawater intrusion and
return/retain water to/in the Los Osos groundwater basin. Highest
priority shall be given to replacing potable water uses with tertiary
treated effluent consistent with Water Code Section 13550.
No amount of treated effluent may be used to satisfy or offset water
needs that result from non-agricultural development outside the
Urban Reserve Line of the community of Los Osos.

Immediate Goals
ͳǤ Halt or, to the extent possible, reverse seawater intrusion into the Basin.
ʹǤ Provide sustainable water supplies for existing residential, commercial,
community and agricultural development overlying the Basin.
Continuing Goals
͵Ǥ Establish a strategy for maximizing the reasonable and beneficial use of Basin
water resources.
ͶǤ Provide sustainable water supplies for future development within Los Osos,
consistent with local land use planning policies.
͹Ǥ Allocate costs equitably among all parties who benefit from the Basin’s water
resources, assessing special and general benefits.
