BACKGROUND
Location and Description of P^roperty
The site of the wastewater treatment facility is approximately
800 feet west of Rancho Santa Fe Road, north of the intersection
of Questhaven Road and Rancho Santa Fe Road in the north east
La Costa area. The two reservoir sites are on property owned
by the La Costa Land Company. One is approximately 3000
feet to the southwest of the treatment plant, and the other
is approximately 4000 feet to the south.
The wastewater treatment facility is at the entrance of the
San Marcos Canyon in a realtively flat, narrow valley. The
two reservoir sites will be placed in shallow valley's.
Existing Land Use
Subject property:
North:
South:
All the property in question is vacant
except for the sewer treatment plant
as explained above.
The nearest residence to the north is
approximately one mile.
Mostly vacant, with some residential
approximately one mile.
East: Mostly vacant, with some industrial
buildings approximately one-half
mile to the east.
West: Mostly vacant with some residential
development approximately one mile to
the west.
History and Related Cases
PDP-2, City Council Resolution No. 5871, approved 8/7/79,
Satellite Sewer Treatment Plant, Lake Calavera Hills.
PDP-2 is similar to the subject application in that it is a
small satellite type plant with wastewater storage facilities.
The approved City Council Resolution for PDP-2 is attached.
City Council Policy on satelite treatment facilities:
At the time of considering PDP-2, the City Council adopted
satelite sewer treatment policies. The policies are in two
parts: one being city wide policies - of these one policy
requires that satelite treatment facilities be also designed
for water reclamation.
PDP-1, City Council Resolution No. 5812, approved 6/19/79,
Expansion of the Encina Joint Agency Wastewater Treatment
Facility.
This application differs from the subject applicaton in that
PDP-1 is a large treatment facility without water reclamation.
ZC-206/MP-149(D), Request for rezoning and Master Plan
Amendment to delete a portion of northeast La Costa from the
La Costa Master Plan. This area will be served by the
subject treatment plant. There actions are presently being
processed and are scheduled for the January 2, 1980 City Council
meeting.
ENVIRONMENTAL IMPACT INFORMATION
An Environmental Impact Report as been certified by the
San Marcos County Water District for the reactivation wastewater
project. Since the project is within the incorporated
boundaries of the City of Carlsbad, the City as a responsible
agency did review and comment on this Environmental Impact
Report. In addition, it is our responsibility to determine
that the mitigating measures as indicated in the Environmental
Impact Report will be met or there are overriding considerations in
approving the project. A copy of this EIR has been distributed
for your information.
GENERAL PLAN INFORMATION
Land Use; The Land Use Element of the General Plan indicates
a public utility site for the wastewater reclamation project,
therefore the project is consistent with the General Plan.
The reservoirs are in areas indicated as low-medium residential.
A storage reservoir is considered compatible with residential
development. Therefore the project is consistent with the
Land Use Element of the General Plan.
Public Facilities: The goal of the public facilities element
is to provide a comprehensive public services and facilities
for the citizens of the City of Carlsbad to insure that all
necessary public facilities will be available concurrent
with need in connection with the development of the City
pursuant to the balance of the General Plan. The reactivation
of this wastewater treatment facility meets this goal of the
public facilities element.
Other Elements; These applications are consistent with all other
elements of the General Plan.
Major Planning Considerations
1. What impacts will the reactivation and operation of
this plant and reservoirs have on the area and have they
been sufficiently mitigated?
2. What are the potential growth inducing impacts caused
by the project and will the projects have precedence for
similar proposals? What will these precedences mean to
the planning process of the public facilities management
program?
3. What guarantees have been established to ensure that
the treated water will be properly used for irrigation
as a substitute for new potable water?
4. Is the proposed expansion desirable in terms of City
policy?
5. What significant environmental impacts, i.e., noise,
visual aesthetics, odors, will result from the proposed
projects, can these impacts be sufficiently mitigated?
Discussion
ZC-207: The property was zoned L-C when it was annexed to the
City last year. The L-C zone is a holding zone, therefore,
the proposed zone change is necessary to bring the property
into consistency with the General Plan category of public
-3-
utility. The flood plain is necessary since the Corps of
Engineers has indicated a portion of the property to be in a
designated flood plain area.
SUP-4: A Special Use Permit is required for all development
in a flood plain as per the Flood Plain Overlay Zone. A
Special Use Permit is basically a report from the City
Engineer on the impacts of such development. The City
Engineer has determined that the proposed construction in
the flood plain will not have an adverse effect on surrounding
or downstream properties (see attached report from the City
Engineer).
PDP-3; The applicant submitted a summary description of the
project, dated September 25, 1979, which is attached. Also
the EIR has a project description which explains the proposal.
The project has been approved by the California Regional Water
Quality Control Board on March 26, 1979. See attached letter
dated March 26, 1979, and Order No. 79-23. The reservoir and
dam must be approved by the State Division of Dam Safety.
The applicant believes approval will be forthcoming about
December 20, 1979. Per City zone requirements the project also
requires City approval. The City's authority is land use.
As per Section 21.36,050 of the Carlsbad Municipal Code, the
City is to determine if the project is consistent with the
P-U zone. The intent of the P-U zone is to provide compatibility
of the development with the general plan and surrounding
development; ensure that due regard is given to environmental
factors; provide for public improvements and other conditions
of approval necessitated by the development.
This narrowing of the City's responsibilities may not appear
consistent with the City's involvement in the Lake Calavera
Hills satelite treatment plant. The two projects differ in
that the Lake Calavera Hills plant is to be City owned and
operated, and the water is generated and reclaimed totally
within the City; whereas the proposed San Marcos County Water
District plant is to be owned and operated by a special
district and some of the water is to be generated and reclaimed
outside of the City. San Marcos County Water District is
however, a special district with authority in both waste
water treatment and water distribution. Questions have been
raised on the jurisdictional responsibilities and the
distribution of reclaimed water. The question has been referred
to the City Attorney's Office.
The present inactive plant has the capacity for 200,000
gallons per day. As requested the plant will be enlarged in
two phases. The first phase is for 270,000 gallons per day,
the final will be for 600,000 gallons per day. It will be
many years before the actual maximum capacity will be met.
The process is to be aerobic, which minimizes odor problems.
The project includes water rec1aimation, by using the water
for irrigation. A balancing reservoir is proposed for the
irrigation water to the southwest, (Rancheros). It
-4-
is possible that this 4.5 million gallon reservoir will not
be needed. A reserve system is also proposed that will hold
water during low water demand periods. This is a reservoir
to the south with a capacity of 57 million gallons,
giving a 90 day reserve. The water reclamation will be
irrigation (land treatment) in specifically designed land-
scaped areas to be approved with later land developments.
Initially reclaimed use will be Type II. However,
as development occurs reclaimed water will be used by these
developments as Type I. (Type I use is water used in a manner
that would normally be served by the potable water system.
Type II use is water used in a manner that normally would not
be served by the potable water system).
During low or no reclaimed water demand times the effluent
from the plant will be pumped to the reserve reservoir. During
irrigation the effluent will come directly from the plant and
the reservoir if needed. Therefore the reservoir will have a
constantly fluctuating level. It is possible that during heavy rain
periods the reserve reservoir will overflow. There is a spill
way planned that will deliver the water to the San Marcos
Creek drainage basin. The Regional Water Quality Control
Board has indicated that the chemical content of this dilluted
overflow will meet their specification. However, they have
requested monitoring.
The water will be given secondary treatment and will be safe
for irrigating near residences. The EIR indicates that the
sprinklers will have low trajectories to reduce water drift.
The irrigation rates will be low to stop runoff, and collector
ditches will be constructed at the toes of slopes to return
runoff to plant. Also there will be collector ditches at the
reservoirs to return seepage to the plant.
This application is similar to the Lake Calavera Hills in
that it is a satellite treatment plant. However, it differs
somewhat in the process in that airation process will be in
open tanks instead of the "race track" cannals of Lake
Calavera Hills. Although the "race track" is superior as
a method and saves energy, the equipment for the tanks are
there and there isn't sufficient space for the "race tracks".
Staff does not believe that the treatment plant and reservoir
will have an adverse impact on surrounding areas as proposed
and conditioned. The plant is relatively small and the
process minimizes obnoxious elements. Reservoirs will appear
as lakes in low density residential areas, be fenced and the
water use should not stagnate because of fluctuating levels.
The plant will not be growth inducing by itself, it will,
however, speed up development in the area. If the City wishes
control of growth in the area, a more effective method would
be a growth management program.
City policy on wastewater treatment plants require Type I
use of the reclaimed water (use of the water in areas that
would normally be served by potable water).
-5-
La Costa Land Company, however, will attempt to reduce the
Type II use as development occurs. They believe that in time
all of the reclaimed water will be used in a Type I manner.
As proposed, the district would require that each user
demonstrate that there is sufficient land available for
the disposal of effluent generated by the development.
These developments will have to provide dual water system for
irrigation use of reclaimed water and the potable water supply,
San Marcos County Water District, as proposed, will operate
the plant and reclaimed water distribution. It will contract
with the homeowners association to use the water. A possible
problem, is that the San Marcos sewer and water jurisdictions
do not have consistent boundaries. There maybe a question
if San Marcos County Water District can distribute reclaimed
water in areas they do not serve with sewer. The project
description indicates that 400,000 gallons per day generate
outside of Carlsbad will be reclaimed in Carlsbad.
Sludge from the treatment will be pressed dried, but will not
be placed in drying beds for complete drying. There is an
odor generated from bed drying and it takes space. Instead
the pressed dry sludge will be trucked to a solid waste
disposal site. This could be a problem from water leaking
from trucks at the disposal site. Although the Regional
Water Quality Control Board has approved the project, staff
has recommended a condition requiring the review of this
disposal method by the County Health Department, County
Department of Solid Waste Management, Regional Water Quality
Control Board and Department of Fish and Game.
The EIR indicates that adequate soils for land irrigation
may be difficult to find in the area. Evidently soils
should be 2 to 3 feet deep for adequate drainage. Most
soil in area are less than 18" deep and are on top of bed
rock or clay deposits. Therefore, it is important that the
applicant supply the City with an irrigation schedule that
relates soils, vegetation and water requirements. This
information should also include analysis on slopes, leaching
needs, monitoring systems, and land properties, etc.
The "examination of criteria" appendix to the EIR indicates
that the storage of the seasonal reservoir needs to have
a 95 million gallon capacity. The proposal is for 57 million
gallons (see Exhibit "A"). It has been confirmed by the
applicant and the City's Public Works Administrator, that the
EIR is in error and the 57 million gallon reserve is
sufficient for a 90 day reserve.
There is no fail safe system designed for plant malfunction.
This is consistent with the Regional Water Quality Control
Board actions on these plants. Evidently the incidence of
•6-
plant malfunction is minor and can be quickly remedied.
As explained earlier, the Regional Water Quality Control
Board has approved the overflow system of the reserve reservoir.
Some of the data or statements made in this report are not
substantiated by the information contained in the EIR or
summary description. However, representatives of the applicant
will attend the meeting to answer your questions and supply
data and substantiation.
Recommendation
ZC-207, staff recommends that ZC-207, be APPROVED as PU with
FP Overlay as per the attached legal map, for the following
reasons:
1. The proposed change of zone is consistent with the
General Plan since the P-U Zone specifically allows
public facilities as indicated on the General Plan
Land Use Map.
2. The P-U zone requires a Precise Development Plan of
Development. Conditions may be placed on the PDP to
meet requirements of the General Plan or any other
needs.
3. The site is physically suitable for the type of use
since the site is adequate in size and shape to accommodate
a sewer treatment plant.
4. The project is consistent with all City public
facility policies and ordinances since the reactivation
of this facility will provide sewer service in the
service area.
5. The proposed change of zone will not cause any substantial
environmental impacts, and an environmental impact
report has been certified by the San Marcos County
Water District for this project. Appropriate mitigating
measures will be taken on subsequent actions to approve
development on the site.
6. The flood plain overlay zone will require Engineering
Report on impacts of construction on flooding.
SUP-4: Staff recommends that SUP-4 be approved based on the
following findings and subject to the condition that all
development and erosion protection measures occur substantially
as shown on SUP-4, Exhibit A and B, dated November 15, 1979,
on file in the Planning Department.
Findings
1. The Special Use Permit is consistent with the purposes
of the flood plain Overlay Zone because the proposed
engineering improvements to the site adequately mitigate
the flood hazard to the site, and have been made conditions
of approval.
-7-
2. The City Engineer has found that no increased flood danger
is likely due to the construction of the wall. Additionally,
the rockwall seems sufficient to protect the treatment
plant from the 100 year flood.
3. The Special Use Permit is consistent with all applicable
specific and general plans because:
A. The use of the site for a wastewater treatment
facility is in conformance with General Plan Land
Use Element designation of public utilities.
B. The proposed engineering improvements to the site
impelemnt the Public Safety Element's goal of
minimizing injury, loss of life and damage to
property resulting from flood disaster.
4. The issuance of the Special Use Permit will not adversely
affect or unduly hinder, restrict or alter the water
carrying function of the floodplain because the proposed
engineering improvements specifically provide for the
safe, efficient disposal of storm water.
5. The project is consistent with all public facility
policies since the site will be used for a wastewater
treatment plant.
6. The subject application has complied with the requirements
of the City of Carlsbad Environmental Protection Ordinance
because an Environmental Impact Report has been certified
by the applicant, and San Marcos County Water District.
PDP-3: Staff recommends that PDP-3 be approved based on
the following findings and subject to the following conditions:
1. The proposed Precise Development Plan ensures compatibility
of the development with the General Plan because:
A. The General Plan Land Use Element designates a
public utility in this area.
B. Subsequent development in the area served by the
treatment plant will be consistent with the General
Plan because all zoning in the service area is
consistent with the General Plan.
2. The proposed Precise Development Plan ensures compatibility
of the project with surrounding development because:
A. Adequate measures are required as part of the
approval, to mitigate any adverse impacts the
property may have.
•8-
B. The location of the project in a valley will
reduce adverse impacts to surrounding prof>erty.
3. It has been determined that the proposed Precise Development
Plan will not result in any siginficant adverse impacts
to the environment due to the following reasons:
A. The conditions of approval include mitigation
measures outlined in the EIR certified by the San
Marcos County Water District and mitigate potential
adverse environmental impacts.
B. The project will be subject to further review and
approval by effected State and Federal agencies.
Said review constitutes additional environmental
impact assessment, and insures the project's
compatibility with the natural manmade environment.
4. The proposed Precise Development Plan provides for
public facilities as necessitated by development and/or
approvals in the area:
A. The proposed wastewater treatment facility will
serve as a complimentary use to the existing
Encina sewer treatment plant by providing the area
with additional sewer capacity.
B. The proposed reclamation facility will reduce the
amount of potable water necessary to serve this
area in the future.
C. Said reclamation system could allow for the pre-
servation and continuation of agricultural production.
D. All other public facilities will be available at
time of development.
E. The project is specifically exempted from the
City's Public Facility Fee Policy (City Council
Policy No, 17) .

SUMMARY DESCRIPTION
of
SAN MARCOS COUNTY WATER DISTRICT
WASTE WATER RECLAMATION PROJECT
September 25, 1979
, PROJECT NO. 021-79-01
September 25, 1979
The San Marcos County Water District waste water reclamation project en-
compasses four District elements, all of which are essential for a functioning
system:
(1) Rehabilitation of the existing District plant and its en-
largement to a capacity of 0.6 million gallons per day;
(2) installation of a reclaimed water distribution system;
(3) construction of a seasonal storage reservoir to hold the
total output of the plant over a 90-day winter period; and
(4) a reclaimed water use area.
The existing plant, located on San Marcos Creek just downstream from Rancho
Santa Fe Road, is about to be repaired and improved after years of use as an
operator's training facility. New units will be added to structures now on the
site to permit treatment of larger flows. The refurbished plant will be capable
of biological secondary treatment, using the extended aeration version of the
activated sludge process. Secondary effluent will be filtered and chlorinated
before use. An emergency generator will supply electricity to operate the plant
during commercial power outages.
An aerobic digester for stabilization of excess activated sludge will be
provided, as well as equipment for mechanical dewatering of digested sludge.
Dewatered digested sludge will be available for soil conditioner, with surplus
hauled to a sanitary fill approved by the Regional Water Quality Control Board.
The Water Quality Control Board has issued "waste discharge requirements" per-
mitting the reclamation program to take place.
Because of its totally aerobic design, the enlarged plant will be odor
free. The existing units operated for many years without odor problems while
serving as the Community sewage treatment plant.
The reclaimed water distribution system will consist of a 12-Inch pipe-
line extending both west and south from the District plant. The westerly branch
will lead to a 4.5 million gallon balancing reservoir in the Rancheros De La
Costa subdivision, about 3000 feet from the plant site. From this point, water
will be pumped throughout Rancheros De La Costa and other proposed subdivisions
to designated areas of agricultural use and landscape irrigation. A total of
zoo
-399' acres will be irrigated, resulting in a water demand averaging 500,000 gal-
lons per day. San Marcos County Water District is presently-seeking a market
for the remaining 100,000 gallons per day.
The southerly branch of the distribution system connects the plant to a
seasonal storage reservoir, located east of Rancho Santa Fe Road, some 3500 feet
south of the plant. Capacity of this earthfill reservoir will be 57 million
gallons, somewhat greater than needed to retain the full plant output of 0.6 mil-
lion gallons per day for 90 days. The seasonal storage reservoir will also
"float" on the distribution system, automatically feeding stored water back to
the Irrigated area as demands increase. Construction of this reservoir is under
permit and supervision of the State Department of Water Resources' Division of
Safety of Dams.
-2-
The entire waste water reclamation operation is under the control of
Regional Water Quality Control Board, which has issued Order No. 79-23, cover-
ing reclaimed water quality, along with permissible and prohibited practices
in the reclaimed water use area. In compliance with Order No. 79-30, all
reclaimed water will be used for irrigation and there will be no discharge of
effluent to streams or other bodies of water.

PRECISE DEVELOPI'lENT PLAN
REVISED CONDITIONS
GENERAL
1. Development of the site shall occur substantially as shovm
on Exhibit "G", dated June 22, 1979, attached hereto,
and as shown on Exhibits A-1, B, D and F-1, dated April 11, 1979,
• for the wastewater treatment plant; and Exhibit A-2, and E,
dated April 11, 1979, for the percolation ponds; except
for modifications and necessary back-up systems not
affecting the plant's operational efficiency that are
approved by the Public VJorks Administrator.
2.. In addition to the approval of the development indicated
in the exhibits noted above, all other requirements and
appurtenances as listed in this approval shall be
indicated on the final Precise Development Plan.
TREATMENT PLANT
3. The proposed treatm.ent plant shall .be constructed in one
phase as a 1.2 mgd capacity plant v/ith percolation ponds,
effluent lines to serve ponds, and all other appurtenances
necessary to operate the treatment plant at its fully rated
capacity of 1.2 mgd. Not v.dthstanding the forgoing phased
construction as specified in Condition #9 herein may be permitted,
4. A reversible force main connecting the treatment facilities
to the Encina line at El Camino Real shall be constructed
• as part of this project.
RECLAI'dATION
5. All wells, pumps, check dams and other appurtenances
necessary to reclaim water from the recharge basin , v/hich
basin is described in Exhibit E, shall be constructed
as part of this project. Plans for the water reclamation
system shall be submitted to and approved by the Planning
Commission prior to commencement of any grading, construction,
or the placing of any equipment for the project.
6. All effluent from the treatment plant shall be reclaimed
and utilized for replacement of existing or, planned potable
water (Type I). The amount of sewer capacity allocated
to future developments shall be limited to the amount
of reclaimied v/ater that can be guaranteed for use by the
applicant of swch development or otherv/ise guaranteed to
satisfaction of the City Council.
Revised Conditions Page 2
7. All proposed users of the treatment plant shall prepare
and provide a plan acceptable tc the City establishing
and guaranteeing a method to utilize any reclaimed
water prior to any approval of their project. The
' reclaimed water may not be applied to native vegetation
or areas where there are no existing or planned potable
water vises. As a guide for determining the acreage of
land necessary to utilize the reclaimed water, the
ratio of gallons of water to acres of. land should be as
follows:
3,000 gallons to one acre of agricultural land, or
800 gallons to one acre of landscaped land per
day.
This ratio may be adjusted by the Planning Director to
accommodate particular locations, soil types and plants.
8. Any plan required by Condition No. 7 shall be submitted to
the Planning Director for approval. Approval of the plan
by the Planning Director shall constitute acceptance of
the plan by the City. In approving the plan, the Planning
Director shall give primary consideration to systems
where the land using the reclaimed water is either near
the recharge basin or served by gravity flow from the
water reclamation system, in order to conserve energy
required for pumping. Approval by the City shall not
constitute a claim to or a guarantee for availability
of reclaimed v/ater. This condition and Conditions 6
and 7 shall be modified as necessary to accommodate
such City plan for the use of reclaimed water as the
Council may adopt.
9. The applicant shall be responsible for construction of
a fail-safe effluent disposal system sufficient to serve
and consistent with the 1.2 mgd design capacity of the
treatment plant, xuiless the. City Council finds and
determines that a water reclamation system consisting
of mains, v/ells, pumps, check dams, and all other
appurtenances necessary to reclaim water from the recharge
basins consistent with such design capacity of the
treatment is feasible. If the water reclamation system
is feasible, its construction is preferrable.
Applicant shall use due diligence to obtain all necessary
state approvals for percolation capacity, first within
the Master Plan boundary of Lake Calavera Hills and then,
if necessary, within alternative recharge basins located
in the Agua Hedionda drainage basin sufficient to handle
the design capacity of the plant.
At the earliest possible time, prior to City's acceptance of
any portion of the treatment facility, the City Council shall
make a determination as to whether (a) it is reasonably
feasible to obtain 1.2 mgd percolation capacity within the
Mastoi" Plan boundary or adjacent alternative recharge basins or,
(b) a disposable effluent fail-safe system should bo built.
c , r-• \ •
Revised Conditions Page 3
Upon either determination, the applicant shall be responsible
for construction and implementation of the alternative
selected.- Plans for the alternative selected shall be
approved by the Planning Commission by a conditional
use permit prior to any grading, construction or placing
of any equipment for the alternative selected. Construction
of the alternative selected shall be completed within
a reasonable time as specified in the Master Reimbursement
Agreement.
The applicant. shall be responsible for the acquisition of
land, easem.ents, or other rights necessary for the construction
required by this condition. In the event the applicant
cannot acquire same after the exercise of due diligence,
the City shall have the option of acquiring the same through
its power of eminent domain, after due satisfaction of all
legal requirements, including environmental review and
public hearings, if required. In such event, the applicant
shall be responsible for the direct expense of environmental
and planning review, retention of special counsel to prosecute
the condemnation action or actions, and payment of any
required compensation to property owners. Acquisition must
be reasonably certain, to the satisfaction of the City,
prior to their acceptance of any portion of the plant.
10. Any appurtenances necessary for reclamation, storage,-or
use of the plant effluent, but not included for approval
in this application, shall be subject to Planning Commission
review and approval. At the tim.e of review the Planning
Commission shall determine if such appurtenances will have
a significant adverse effect on surrounding property. If it
is determined that the appurtenances may have a significant
adverse effect a conditional use permit shall be required.
Such conditional use permit shall contain conditions sufficient
to mitigate any such potential significant adverse effect.
11. The applicant shall be financially responsible for and shall
make all reasonable efforts to acquire and provide a thirty
foot wide access way from Tamarack Avenue to the treat-
ment facility, with necessary easement rights to accommodate
the reversible force main required by Condition 4 hereof.
In the event applicant cannot acquire same after the exercise
of due diligence, the City shall have the option to acquire
the same through its power of eminent domain, after due
satisfaction of all legal requirements, including environ-
mental review and public hearings, if required. In such
event, the applicant shall be responsible for the direct
expense of environmental and planning reviev/, retention of

CITY COUNCIL POLICIES ON CALAVERA HILLS WASTEWATER
TREATMENT PLANT
The Carlsbad City Council has approved the following new City
policies in their consideration of the Calavera Hills treatment
plant. I have listed the policies in two groups, the first being
those policies applying to the City generally and the second
being those policies related directly to the proposed Calavera
Hills wastewater treatment plant.
A) City Wide Policies:
1. It is the City Council policy and determination that a
satellite treatment facility is acceptable in the north-
east drainage basin of the City.
2. The City Council has determined that no wastewater
facility will be considered by this Council unless it
is also designed to be used for water reclamation.
3. The City Council has determined that it is necessary to
develop a city wide reclamation policy including the
principle uses of reclaimed water and has requested City
staff to develop a work program for a reclamation policy.
4. City Council has reguested City staff to prepare a work
program for agricultural land preservation for the City.
5. City Council requested staff to prepare a work program
providing for mitigation of growth inducing aspects
considered in -the Montgomery report as follows:
a) Public facilities element and capital improvement
program.
b) Mandated General Plan review every three years.
c) Urban land reserve program.
d) Growth monitoring program.
e) Specific Plan for special treatment areas.
f) Work plan which includes a City growth management
program.

B) Determinations directly related to Calavera Hills;
1.
2.
3.
City Council indicated a preference for the alternate
site 3-B identified in the Montgomery Report.
City Council indicated desire to review pump station
sites along with the treatment facilities for environ-
mental considerations.
City Council accepted the percolation beds contained in
the Montgomery Report and indicated their desire to study
and analyze potential recharge areas near Rancho Carlsbad
Mobile Home Park.
City Council determined that additional failsafe lines
beyond the normal back-up systems to be built into the
plant not be included for raw sewage and further deter-
mined it would delay a decision on an effluent failsafe
system until an overall Master Plan of satellite treatment
plants has been adopted by the Council.
City Council determined that a 1.2 mgd plant will be built
initially at the Lake Calavera Hills site.
City Council determined that the financing for the plant
will be provided by the developer and that the developer
and staff shall enter into negotiations which will,
hopefully, require a minimum of reimbursement and City
involvement in the financial aspects of the project.
When staff and developer complete their negotiations, they
shall return to the City Council for their approval.
City Council determined that the City will maintain and
operate the plant after completion.

TO: Planning Director
FROM: CUy Engineer
DATE: Novaisber 28, 1979
SUBJECT; Report of City Engineer for Construction In the
Flood Plain Overlay Zone
In accordance with City Code Section 21.31.100, I have reviewed the
Special Use Pemlt for tha San Marcos County Water District Sewage
Treatnent Plant.
a) The existing treatjnsnt plant lies partly within the line of
Inundation for the San Marcos Creek, The 100-year flood
would conceivably damage the treatment plant.
b) To mitigate the potential flood problem, the District Is pro-
poslgg the construction of a rock wall to protect the treat-
ment plant site.
c) Water surface profile Information shows no significant change
In depth In the creek bed during the IQO-year storra for
locations upstream or downstream of the wall.
d) The 100-yaar design flow of 13000 cf^ through the creek bed
section narrowed by the rock wall will create Increased
water velocities In this section of the channel.
Our review of the proposed dsveloptnent indicates that no Increased
flood danger is likely due to fie construction of the wall. Addition-
ally, the rock wall seems sufficient to protect the treatment plant
froi the 100-year flood.
The County Flood Control District has also been asked to evaluate the
possible flood hszard since the site Is within Zone 1 of that District.

CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD
SAN DIEGO REGION
ORDER NO. 79-23
WASTE DISCHARGE REQUIREMENTS
FOR
SAW r4ARC0S COUNTY WATER DISTRICT
WASTEWATER RECLAMATION PROJECT
NEAR SM MARCOS CREEK
The California Regional Water Quality Control Board, San Diego Region (hereafter
Regional Board), finds that:
1. Mr. James F. McKay, Secretary/General Manager, San Marcos County Water
District (District), submitted an incomplete Report of Waste Discharge dated
December 5, 1978, proposing to treat and dispose of up to 0.6 million
gallons per day (MGD) in a wastevater reclamation project to be located
southerly of Lake San Marcos and easterly of La Costa in San Diego County.
After receipt of additional information requested by Regional Board staff,
the completed Report of Waste Discharge was accepted on February 22, 19T9-
2. The discharger proposes to reactivate and expand their activated sludge
secondary treatment plant located near San Marcos Creek downstream of Rancho
Santa Fe Road. The plant was taken out of service in I969 when the District
began ocean disposal through the Encina Water Pollution Control Facility. ,
The District wishes to reactivate the treatment plant to (l) reuse water
that might otherwise be discharged to the ocean, and (2) provide additional
wastewater treatment and disposal capacity. Additional treatment linits would
be added thus bringing the plant's total capacity to 0.6 MGD of oxidized,
coagulated, filtered, and disinfected wastewater.
3. The 0.6 MGD of treated wastewater would be used to irrigate landscaping,
crops, and open space. Excess effluent would be disposed of by land appli-
cation. Provisions would be made to dispose of up to 0.5 MGD within the
Rajicho La Costa development on 177 acres. It is anticipated that additional
uses would be developed in the San Marcos area to establish a demand for the
remaining 0.1 MGD of treated wastewater.
k. The District proposes to construct a seasonal storage reservoir (l75 acre-
feet) that would contain the treatment plant's effluent output for 90 days.
The reservoir would store effluent during periods when irrigation disposal
could not be used because of inclement weather. The location of the waste-
water treatment ajid storage facilities are shown in Attachment No. I.to this
Order.
5- The discharger reports that the sludges produced by the treatment processes
would be aerobically digested then mechanically dewatered. The processed
sludge would be made available for nearby agricultural or landscaped areas
and surplus digested sludge would be disposed of at an approved sanitary
landfill. The discharger reports that the Encina Joint Powers Regional
Order No. 79-23 -2-
Sewerage Agency (JPRSA) is currently studying an alternative regional
solids handling program and if carried out, the District's sludge would
be transported to the Encina Water Pollution Control Facility via sewer.
6. The District proposes to implement the above plans in two major phases.
The first phase would be the rehabilitation of the existing facilities to
provide a treatment capacity of 0.2 MGD. The 175 acre-foot storage reser-
voir would be completed in this initial phase and a portion of the irri-
gation system with sufficient piping to irrigate 75 acres (0.2 MGD) within the
Rancheros De La Costa development within the Rancho La Costa development.
The next phase woLild involve expanding the wastewater treatment and disposal
capacities to 0.6 MGD. The treatment portion of this phase is expected to
be operational within nine months after beginning operation of the first
phase; however, the disposal capabilities are expected to be provided in
increments as the wastewater flows increase. The general locations of the
effluent disposal sites are shown in Attachment No.II of this Order.
7. The District proposes to install a dual water system in the Rancheros De La
Costa subdivision; one system would distribute potable water while the other
system would distribute treated wastewater to the estate size lots for irri-
gation of landscaping and crops. The La Costa Land Company, developer,
would (l) install the dual distribution system; (2) provide area for waste-
water disposal within the subdivision; (3) establish a plan of plantings;
(U) form an organization to manage and operate the disposal system; and (5)
use conditions, covenants and restrictions to ensure individual homeowner
participation. Other dual water systems would likely be proposed for other
disposal areas as they are developed.
8. The discharger reports that the full treatment and disposal facilities would
provide sewerage service for about 2,ii00 single family dwelling units and this
level of development is expected to take 11 years to complete. The I98O, I985
and 1990 wastewater flows are expected to be 0.135 MGD, O.506 MGD, and 0.6 MGD,
respectively.
9. The District reports that the project is for residential development only
and industrial wastewater flows are not expected. The District would prohibit
the use of onsite self-regenerated water softeners and the expected waste-
water total dissolved solids (TDS) with Colorado River water as the supply is
1,100 mg/1. The expected blend of Northern California water in the supply
would lower the effluent's TDS to 85O mg/l.
10. The District supplies potable water to the development area and currently
obtains its water supply from the San Diego County Water Authority. This
water supply is imported Colorado River water and Northern California water.
At the present time a blend containing 529 mg/l TDS is being distributed;
however, this blend and hence water quality is subject to change.
11. The dischajTger reports that the wastewater treatment, transmission, and stor-
age facilities would be protected against runoff and flooding by 100-year
frequency rainfalls and flood flows. The District further reports that the
public would be excluded from the wastewater treatment and storage facilities.

Order No. 79-23 ~ -3-
12. Ifr. Dennis O'Leary, Lowry and Associates, consulting engineer for the
District, reports that the volume of subsurface flow leaving the disposal/
irrigation areas is not expected to cause surface seeps as it moves down-
stream underground. Mr. O'Leary further reported that if the assumptions
regarding underflow prove incorrect, one or more of the following methods
would be used to stop surfacing of leachate: (l) revising irrigation
practices in areas contributing to surface seeps; (2) capturing seepage
and recycling to the reclamation operation; (3) planting phreatophytes at
key locations; (k) capturing seepage for use elsewhere; (5) capture seepage
for use in decorative lakes/evaporation ponds; (6) capturing seepage for
ocean disposal through the Encina JPRSA system; and (7) capturing seepage
for desalting with product water being used beneficially ajid waste brine
being discharged to the ocean.
13. The discharger reports that the precise location of the landscaping and crop
areas would not be known until the subdivisions are designed and approved.
As such, the data reviewed in preparation of drafting these waste discharge
requirements were not site specific. As a result, the Regional Board staff
in cooperation with the State and County Health Department staffs, will
review and approve the specific disposal sites. The approval of the treat-
ment and disposal concept addressed in'these waste discharge requirements
is not approval of specific disposal areas and methods.
ik. The District reports that they would accept basic responsibility for the
wastewater reclamation project including the ultimate responsibility for
meeting these waste discharge requirements. The day-to-day operation of the
irrigation facilities and sched\iles would be by a separate properly organized
entity, which is currently under study. The District would instruct and
supervise the operating organization to ensiire that waste discharge violations
do not occur.
15. The existing and proposed expansion of the wastewater treatment facilities
are located in the SIh of the NE?i;, Section 30, T12S, R3W, SBB&M. The pro-
posed effluent storage pond is located in the N?2 of the NW^rj, Section 32,
T12S, R3W, SBB&M. The proposed effluent disposal areas would generally be
located in Sections 19, 20, 29 and 30, T12S, R3W, SBB&M. The wastewater
reclamation project is located in an area with no groundwater quality . \
objectives in the San Marcos Hydrologic Subunit of the Carlsbad Hydrologic Unit.
16. The "Comprehensive Water Quality Control Plan Report for the San Diego
Region (9)" (Basin Plan), adopted by this Regional Board on March 17, 1975
and approved by the State Water Resources Control Board on March 20, 1975,
and updated by the Regional Board on February 27, 1978, established the
following objectives for svirface and grovmd waters in the San Marcos Hydro-
logic Subxinit;

17- The Basin Plan also contains the following prohibitions applicable to the
proposed discharge:
"Discharge of treated or untreated sewage or industrial waste-
water, exclusive of cooling water or other waters which are
chemically imchanged, to a watercourse, is prohibited except in
cases where the quality of said discharge complies with the
receiving body's water quality objectives.
"Discharging of treated or untreated sewage or industrial wastes
in such manner or volume as to cause sustained surface flow or
ponding on lands not owned or under the control of the discharger
is prohibited except in cases defined in the previous paragraph
* The groundwater objectives do not apply between Hwy 78 and El Camino Real
** Concentrations of nitrogen and phosphorus, by themselves or in combination
with other nutrients, shall be maintained at levels below those which stimu-
late algae and emergent plant growth. Threshold total phosphorus (P) con-
centrations shall not exceed 0.05 mg/l in any stream at the point where it
enters any standing body of water, nor 0.025 mg/l in any standing body of
water.
***Ninety percent or more of natural seasonal minimum oxygen concentration and
more than 5.0 mg/l maintained at least 90 percent of the time.
NOTE: JTU = Jackson Turbidity Units mg/l = milligrams per liter
Order No. 79-23 -5-
and in cases in which the responsibility for all downstream
adverse effects is accepted by the discharger.
"The dumping or deposition of oil, garbage, trash or other
solid municipal, industrial or agricultural waste directly
into inland waters or watercourses or adjacent to the water-
icourses in any manner which may permit its being washed into
the watercoiirse is prohibited.
"Land grading and similar operations causing soil disturbance
which do not contain provisions to minimize soil erosion and
limit suspended matter in area runoff are prohibited."
18. Surface waters in the San Marcos Hydrologic Subunit are beneficially used
for:.
(a) Agricultural supply
(b) Water contract recreation
(c) Nonwater contact recreation
(d) Warm freshwater habitat
(e) Wildlife habitat
(f) Preservation of rare and endangered species
19. Groundwaters in the San Marcos Hydrologic Subunit are beneficially used
for:
(a) Municipal and domestic supply
(b) Agricultural supply
(c) Industrial service supply
20. The San Marcos County Water District has prepared a final environmental
impact report in accordance with the California Environmental Quality Act
(Public Resources Code Section 21000 et seq.) and the State Guidelines.
21. The District has changed or altered the project as follows:
a. Vegetation in the landscaping to receive reclaimed wastewater will
be selected not only for its ornamental value but also for its
high consumptive use and potential for high nutrient removal.
b. The effluent will be secondary treated including coagulation,
filtration, and disinfection to a level safe for irrigation neax
residences.
c. Low trajectory sprinklers will be used to guard against the drift
of atomized reclaimed water into neighboring homes.
d. The irrigation rate will be regulated so that there would be no
runoff. As an additional safeguard against runoff and seepage,
collection ditches will be placed at the toes of slopes.
Order No. 79-23 -6-
e. Water collected at the toes of slopes will be monitored for
phosphorus and nitrogen concentrations. High concentrations
will call for reapplication of the water to the landscaping;
low concentrations could allow discharge of the water to the
creek. Such monitoring is especially important during the
first rains of the rainy season and as salts are periodically
leached from the soils in the landcaped areas. If necessary,
plant capacity trade-offs could be arranged to discharge
leachate through an ocean outfall.
f. There will be a collection ditch below the dam to catch any
seepage from the reservoir. That water would be returned to
the reservoir.
g. . The proposed treatment plant design will have back-up systems
to prevent adverse impacts in case of failvire of the main
system.
h. Construction of the reclaimed wastewater irrigation system will
comply with Title 17 of the California State Administrative Code
by including a water master on the job to monitor pipe con-
nections and to prevent cross-connections of the reclaimed water
lines with potable water lines.
i. The irrigation system will be maintained and operated by the
San Marcos Coxinty Water District under a contractual agreement
that will give them total assurance that they will always have
the ability to discharge the effluent safely and efficiently.
j. The proposed sewage treatment facilities will use aerobic processes
to minimize the potential for odor. A sludge filter press will be
used at the end of the treatment process to minimize the storage
time of sludge onsite. The sludge handled through the filter press
will be transported offsite to a county landfill or to be used on
domestic gardens. Malfunctions in the treatment system resulting
in odors will last in most cases only a few hours and rarely more
than one or two days. Also, there will be enough fluctuation of
the level of water in the reservoir through either irrigation use
or the infusion of rainwater to prevent odors from occurring at the
reservoir due to, stagnation of the effluent.
22. The changes or alterations of the project mitigate or avoid the adverse
water quality impacts of the project.
23. The Regional Board has considered all environmental factors associated
with the proposed discharge of waste.
2U. The Regional Board has notified the discharger and all known interested
parties of its intent to prescribe waste discharge requirements for the
proposed discharge.
Order No. 79-23 -7-
25. The Regional Board in a public meeting heard and considered all comments
pertaining to the proposed discharge.
IT IS HEREBY ORDERED, That the San Marcos County Water District shall comply
with the following waste discharge requirements for the wastewater reclamation
project:

exactly what areas will be rezoned to the floodplain overlay zone* It
would be helpful If you could place a sates and bounds description of
