STATEMENT OF THE MPlTTER
The request is to reactivate existing inactive 200,000 gallon per
sewer treatment plant to a 600,000 gallon per day treatment plant,
The process will be aerobic which mininizes odor problem. The effluent produced by this plant will be placed in a 57 million ga: reservoir south of the treatment facility. Water frolr. this resen
and from the plan will be disposed of by spraying in landscaped
areas. (Land application) .
It is proposed that future development will provide dual vater syz
to use this reclaimed water for landscaped areas within developn?er
their developments. The remaining 100,000 gallons will be used ir
developments in the San Ptarcos area.
At the Planning Commission meeting the applicant made a full presc
explaining all aspects of this project, especially those not full: covered by the EIR project description or their application. T!
applicant submitted an addendum to the "Summary Description",

public utility in this area.
Subsequent development in the area served by tl
treatment plant will be consistent with the Ger Plan because all zoning in the service area is
consistent with the General Plan.
b.
2. The proposed Precise Development Plan ensures compa-
of the project with surrounding development because
a. Adequate measures are required as part of the
approval to mitigate any adverse impacts the p
may have.
b. The location of the project in a valley will r I adverse impacts to surrounding property.
3. It has been determined that the proposed Precise De
Plan will not result in any significant adverse imp
to the environment due to the following reasons:
a. The conditions of approval include mitigation
measures outlined in the EIR certified by the
Marcos County Water District and mitigate pote adverse environmental impacts. 1 b. The project will be subject to further review ' approval by effected State and Federal agencie

GENERAL PLAN INFORMATION
Land Use: The Land Use Element of the General Plan indicates
a public utility site for the wastewater reclamati.on project,
therefore the project is consistent with the General Plan.
The reservoirs are in areas indicated as low-medi um residenti
_I_-
A storage ]:.eservoir is considered compr,tj.b:Le with residential
development. Thererore 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 pcbiic services and facilities
for the citizens of the City of Carlsbad to insilre that all
necessary public facilities wi.l.1 be available concurrent
with need in connection with the develcpment of the City
pursuant to the balance of the General Plan. The reactivatio
of this wastewater trea-tment facility meets this qoal of the
public facilities element.
Other Elements: These applic?.tions a.re consistc>nt with all o
elements of the General Plan.

3. What guarantees have been established to ensure that
the treated water will he propel-1.y used for irrigation
as a substitute for neb: potable water?
4. Is the proposed expansion desirabl~c in terms of City
policy?
5, What significant environmental impacts, i.. e. , noise,
visual aesthetics, odors, will rc:s;ult from the proposed
projects, can these impacts be suEficient,ly mitigated?
Discussion
ZC-207: The property was zoned L-C when it was annexed to t
.City last year. The L-C zone is a holding zone, therefore,
the proposcd zone change is necessa.ry to brinq the property
into consistency with the General I?lan category of public

uti.lity. 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
Special Use Permit i.s 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 surroundin!
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, whi.ch is attached. Also
the EIR has a project description which explains the proposal
The. project has been approved by the California Regional Wate:
Quality Control Roard on March 26, 1979. See attached 1.etter
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
Decembcr 20, 1979. Per City zone requirements the project a1
requ$res City approval. The C<.ty's authorj.ty is land use-
As per Section 21.36.050 of the Carlsbad Flunicipal Code, the
City is to determine if the project 2s consistent with the
P-U zone. The intent of the P-U zone is to provide compatibi
of the devel.opnent with the general plan and surroundi.ng
development; ensure that due regard is given to environmental
factors; provide for publ.ic 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. J,ake Calavcra Hills plant is to be Ci.ty owned and
operated, and the water is generated and reclaimed totally
within the City; whereas the proposed San Yarcos County Water
District plant is to be owned and operated by a special
district. and some of the water is to he generated and reclair
outside of the City. San Marcos County Water Disfrict is
water treatment and water distribution. , Questions have been
raised on the jurisdictional responsibilities and the
distribution of reclaimed water. The question has been rer'ei
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 enlaryed 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 wi.11 be met.
The process is to be aerobic, which minimizes odor prohl.cms.
The project includes water reclaimation, by using the water
€or irrigation. A balancing reservoir is proposed for the
irrigation water to the southwest, (Rancheros). It
-- in a flood plain as per the Flood Plain Overlay Zone. A
however, a special district with authority in both waste
-4-

\ is possible that this 4.5 million gallon reservoir will not
water during low wat-er 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 wi.th later land developments.
Initially reclaimed use will be Type 11. Iiowevcr,
as development occurs reclaimed water will be used by these
developments as Type I. (Type I use i.s water used in a manne
that would normally be served by the potable water system.
Type I1 usc is water used in a manner that normally would not
be served by the potable water system).
During low or no reclaimed yater deman'ii times the effluent
from the plant will he pumped to the reserve rescyvoir. ,Duri
irrigation the effluent will come directly from the plant ant
the reservoir if needed. Therefore the reservoir will have c
periods the reserve reservoir will overflow. There is a spil
way planned that will deliver the water to the San Marcos
Creek drainage basin. The Reqional Water Quality Control
Board has indicated that the chemical content of this dillute
overflow will meet their specification. However, they have
requested monitoring.
The wa.ter will be given secoridary treatment and will be safe
for irrigating near resideiiccs. The EIR indicates that the
sprinklers will have OW trajectories to reduce water drift.
The irrigation rates ~7ill be low to stop runoff, and collectc
ditches will be constructed at the toes of slopcs to return
runoff to plant. Also there will be collect.or ditches at thl
reservoir:; to return seepage to the plant.
This application is similar. to the Lake Calavera Hills in
that it is a satellite treatment plant. Eowevcr, it differs
somewhat in -the process in khat airak-ion process tqi11 be in

Calavera Ili.1.i~ ./ Although t-hc "race trackaG is superior as
a method and saves energy, thc equipment. for the tanks are
there and there isn't sufficient space for the "race tracks"
Staff does not believe that the treatmcnt plant and reservoi
will have an adverse impact on surrounding areas as proposed
arid condltioned. The plant is relatively small and the
process minimizes obnoxious elements. Reservoirs will appea
as lakes in low density residential areas, be fcnc.cd and t1iE
water use should not stagnate because of fluctcating lcvcls.
The plant will not be growth inducing by itself, it will,
however, speed up development in the area. If the City wisk
control of growth in the area, R more effcctive.method wouli
.be a growth management program.

La Costa Land Coixpanl7, however, will attempt to reduce the
~ypc 7:I use as devc:lopment occurs. They believe that in tin\€!

As proposed , the district would require that each user
de,monstrate tk1.a t there j.s suffi.cient land available for
the disposal. of effl.uc:it generated by the development.
These developments will. have to provide dual.. water system for

Sludge from the treatment will he pressed dried, but will not
be placed irl dryinq beds for complete drying. There is an
odor gencxil-aLed from bed drying and it takes space. Instead
the pressed dry sludge -&Till he trucked to a solid waste
d:i.sposal. site. This could he a prob'iem from water leaking
froin trucks at the disposal site. Although the Regional
N?Aker Qual-! i-y Co~ti-01 Zoard has approved the project, staff
has recoirlj11c;?c!nrl a condition rea-uiring the review of this

Thc ETR irliiicates that adeguate soils for land irrigation
may be difiricult to fi.nd in the area. Evidently soi.1~
should be 2 to 3 feet deep for adequate drainage. Most
soi.1 in arc!c: are less than 18" deep and are on top of bed

The "exarni.n,zt.ion of criteria" appendix to the EIR indicates
that the st.oragc of 'i1-1~ seasonal reservoir needs to have
a 95 millinn gal lo:^ capacity. The proposal is for 57 millio

LA COSTA NORTHEAST IRRIGATION PLAN
(1) Briefly described, the irrigation system will consist of two
major phases. The first phase will utilize so-called Type I1
application, which will gradually be replaced by a Type I(2) system a5 development occurs.
Although Type TI application is less desirable than Type I, it
is an interim measure cnly and is necessary for the reclaimed
water system to be viable.
Such a phasing is necessary because La Costa is required to acce and use a far greater percentage of the water produced by the pl than will be generated by them(83% and 33% respectively, equal t
500,000 gpd and 200,000 gpd). In later development this will no
a problem. The Rancheros Subdivision, for example, is a large
development(average 3.8 acre per dwelling unitland will consume
much more water than it will produce. However, these lots will
most likely be developed individually, and permanent landscapinc - installed at that time. Therefore, an interim system is require
to consume the water generated from the San Marcos area.
The interim system will be an asset to the area because the plar chosen have a wide tolerance range for water consumption(from 16 inches per year natural rainfall up to 64 inches per year). ThE
fore, as Phase 11 replaces the Type I1 landscaping, the plants \ Survive and continue to beautify the area.
The plants chosen are also very salt-tolerant and, with occasioi
leaching with potable water,will easily accept the salts in the
reclaimed water.
We have also chosen deep-rooted species to break up the clay-li!
soil and so encourage percolation.
(1) Type TI use is water used in a manner that normally would
be served by a potable water system.
Type I use is water used in a manner that would normally b
served by a potable water system. (2)

- The application rate averages 2500 gallons per day per acre;
however this application rate ranges from 980 to 6600 gallons
per day per acre(January and July, respectively).
La Costa's allocated storage in the reservoir is 47.5 million
gallons. In the Phase 1 program, as much as 47.0 million gallon:
may be stored, however this will stabilize to 46.8 million galloi
in Phase PI(based on an average 30 year rainfall figure with a
50% safety figure added). .
Xn summary, we believe that, although Phase I: is a necessary seg rnent of the overall reclamation project, and brill eventually be
phased out, it will leave the City of Carlsbad and La Costa an
area that is aesthetically pleasing and beneficial to them.

B) Determinations directly related to Calavera Hills:
1. City Council indicated a preference for the alternat site 3-B identified in the Montgomery Report.
City Council indi-cated desire to review pump station
sites along with the treatment facilities for envirc
mental considerations.
City Council accepted the percolation beds containef the Montgomery Report and indicated their desire to
and analyze potential recharge arleas near Rancho Cai
Mobile Home Park.
City Council determined that additional f ailsaf e 1i1

City Council determined that the financing for the will be prGvided by the developer and that the deve and staff shall enter into negotiations which will,
hopefully, require a minimum of reimbursement and C involvement in the financial aspects of the project

MEMORANDUM
DATE : December 31, 1979
TO ; Wayne Dernetz, City Manager
FROM: James Hagaman, Planning Director
SUBJECT : SAN MARCOS WASTE WATER TREATMENT PLANT
PDP-3
The Planning Commission has recommended approval of the
subject Precise Development Plan with conditions.
Planning Commission's action was based on land use and the
did not consider the issue of who has the authority of
distributing reclaimed water.
Staff believes a condition should be added that requires
the City and San Marcos County Water District to enter into
an agreement that permits SMCWD to distribute water within
the City of Carlsbad. This is desirable since some of the
areas that the reclaimed water could be sprayed upon are in the Olivenhain Water District (including the storage
reservoir).
Recommendation
It is recommended that the following condition be added to
the recommended approval of PDP-3.
The
intent of the Public Utility Zone. The Planning Commission
23. Prior to approval of the final Precise Development
Plan, the San Marcos County Water District shall
enter into a service agreement with the City of
Carlsbad to permit the distributing and disposing
of water from the waste water treatment plant
on property within the incorporate limits of the
City of Carlsbad.
