I. INTRODUCTION
During the 197O 1 s, the properties in the vicinity of Palomar Airport,
which represents almost a geographical center of our Water District,
has experienced tremendous development from the standpoint of busi-
ness, commercial, and industrial developments. In recent times,
attention has focused upon the triangle formed by Palomar Airport
Road on the south, El Camino Real on the north and the east, and the
City limits of the City of Carlsbad along the alignment of the
upper areas of the Agua Hedionda Lagoon. This triangle, comprising
some 2,000 acres of land, represents the only area of the Water
District west of El Camino Real that has not, to date, been carefully
evaluated from an engineering standpoint for the development of a
public water system that would meet the ultimate development require-
ments as set forth in the approved 1 and-use pl ans for the area.
Accordingly, it is very timely for the Board of Directors of the
Water District to consider the specific request of the Koll Company,
developers of the proposed Carlsbad Research Center, to proceed
with a "master plan study'' pursuant to the current District policies
and guidelines. The Water District conducted a poll among the entire
ownership of the triangle area and, with a substantial response on
the part of those properties for their concurrence of a need to
perform the study and their wi 11 i ngness to share in the expense
thereof, the District proceeded with the authorization of this study.
In addition to the initially proposed commercial and industrial deve-
lopment immediately to the north of Palomar Airport, v-1e have had
planning programs brought forth by the Signal Landmark Group for the
-1-

properties a 1 ong the southwest and westerly area of Pa 1 omar Airport
and there is also intensive activity by the City of Carlsbad for the
development of the Macario Canyon Regional Park. Likewise, there is
now coming to a final determination land-use planning in the area of
the Agua Hedi onda Creek wetlands and shoreline areas so that public
water service needs assessment can be readily accomplished at this
time.
The actual study program and its results and recommendations are set
forth within this report; however, we call specific attention to the
fact that during the course of our study program, there has advanced
substantially the development concepts on the part of the co11111ercial
industrial developments for the utilization of non-potable water for
the various landscaping, greenbelt, and other uses that would not
require potable water (fresh water service). In fact, the concept
of the construction of a separate water system that would convey
such non-potable water is a part of the overall development concept.
For the purposes of this engineering study, we have taken into account
the design of the public water system and reservoirs to accommodate
the ordinary water service requirements of such developments, without
regard to the impact that there may be with the utilization of non-
potable water. Our evaluation of this potential future would indicate
that insofar as the potable water system of the development areas is
concerned, that use will be governed primarily by the domestic,
industrial, and commercial uses together with the required fire
flows; however, as the non-potable water service program emerges in

a defined manner, we shall assess the impact upon the overall char-
acter of the public water system that is distributing potable water.
We acknowledge the assistance and cooperation of the City of Carlsbad
in the preparation of this report. The Planning Department has pro-
vided all of the input for land-use, zoning, and population projec-
tions. The City Fire Department has provided suggestions and recom-
mendations with respect to levels of fire protection service and
the Engineering Department has provided the guidance on the develop-
ment of the arterial street system and the requirements of public
water service of the City of Carlsbad -Water Department. Rick
Engineering -Carlsbad office, acting in their capacity of consulting
engineers for the Carlsbad Research Center and the Si gna 1 Landmark
Development area, provided substantial technical data, base maps,
and other important information •

II • SCOPE ANO PROCESS OF STUDY
The 1 imits of the study are as shown on the "Master Pl an of the Public
Water System -Improvement Districts 2 and 3 -Palomar Airport
Area," on the map marked "Exhibit A", an attachment to this report.
This area, in general, consists of those lands lying north of Palomar
Airport Road and south and west of El Camino Real and easterly of
the City water service limits of Carlsbad.
The topography of the area is made up mainly of a large mesa, which
contains the Palomar Airport with several low peaks and valleys
extending into Agua Hedionda Lagoon. Elevations vary from a high at
Evans Point of 357 feet to a 1 ow of near sea level at the Lagoon.
The total area under consideration is approximately 2050 acres which
includes a small portion of the City of Carlsbad retail service area
and the Palomar Airport. The land use of the area is established by
the City of Carlsbad with their Land Use Plan. (See Exhibit 11 B11
)
Population projections were calculated using the maximum allowable
density for each particular area. The proposed industrial area was
analyzed according to existing tentative maps filed by the Koll Co.
and Signal Development Corporation.
The operating pressure within the study area was redefined and new
pressure zones proposed. These zones are set using current develop-
ment trends and California Department of Public Health guidelines.
The minimum allowable pressure has been set at 40 psi and a maximum
working pressure of 150 psi. The minimum pressure may be as low as
20 psi under fire flow conditions.

The hydraulic parameters upon which the study is based are consumption data
based on District records and previous studies within the District of 150
gallons of consumption per capita per day. The maximum daily consumption
per capita is twice the average daily consumption of 150 gallons, or 300
gallons per capita per day. A peak hour demand was estimated to be twice
the maximum daily consumption, or 600 gallons per capita. Pipe sizes
were calculated using the maximum day plus fire flow or peak hour
demand, whichever was greater.
Water consumption for institutional (schools) areas was assigned an annual
factor of 2.5 acre-feet per acre. Water consumption within industrial
areas was assigned an annual factor of 3.5 acre-feet per acre. Special
consideration was given to large open space areas and the proposed regional
park which was assigned an annual factor of 2.0 acre-feet per acre.
The estimated fire flows were determined with the guidance of the Fire
Marshal of the City of Carlsbad utilizing current insurance underwriter's
requirements based on a prediction of the type of construction that will
be used in the area. The subject fire flows are summarized in Table I
of this report.
Water main sizes were determined using a maximum velocity within the pipe-
1 i nes of eight (8) feet per second and a minimum pressure of 40 psi,
except during fire flow conditions when residual pressures of 20 psi are
allowed. The maximum flow in each of the pipelines was based on the
maximum daily consumption plus the required fire flows or peak hour

demands, whichever was greater. In addition, the pipelines are sized so
that head 1 asses due to friction wi 11 not result in pressure reduct i ans
below those previously stated. Maximum pressure has been set for 150
psi, except in the Palomar Airport area where higher pressures may be
desired. This high pressure represents a maximum pressure at static
conditions.

II I. LAND USE
The study area consists of lands that are within the City of Carlsbad
and the County of San Diego. The City of Carlsbad adopted a Land Use
Pl~n on August 16, 1974, by City Council Resolution No. 3527, and re-
vised by General Plan Amendment on February 9, 1979, and this Land
Use Plan includes all of the area within this study and as shown on
"Exhibit B" of this report. The principal land-use designations are
shown on "Exhibit B." In addition to this Land Use Plan, there are
various proposed tentative subdivision maps, the Agua Hedionda Speci-
fic Plan (currently being reviewed by the Coastal Commission) and
the proposed Marcario Canyon Regional Park in the study area.
Where available, this detailed information was used to make the
study more definitive and precise. There needs to be future reviews
when the specific plan and park plan are formalized.
For those areas where there are tentative tract maps, the densities
or areas shown on those maps were used in computing the population
or use in those areas. The population was estimated on the basis of
an average of 3.5 persons per dwelling unit for low density residential
(less than eight (8) dwelling units per acre), 3.0 persons per dwelling
unit for 10 units or more per acre, and 2. 5 persons per dwe 11 i ng
unit for 20 units or more per acre. For those areas where the only
information available was Land Use Plans or Specific Plans, the
population and density estimates were made using the maximum densities
as shown on those plans •
-7-

Based upon the Land Use Plan and utilizing the above factors, the ul-
timate population for the study area is estimated to be 6,500, con-
sidering about 1/2 of the RL zoned land as future park.

reducing station at El Camino Real, and the 16-inch feeder from the
20-inch El Camino Real main extending across the study area north of
the airport to Reservoir 11 E.11
There also is an existing 6-inch, 10-inch, and 12-inch line extending
into the northern part of the study area as shown on 11 Exhibit A.11 A
10-inch line feeds water to the City of Carlsbad on the westerly side
of the study area. The future use of these lines will depend on the
development plans of the area •

Since the study areas are not currently served by pressure zones, it
is necessary to establish pressure zones that meet current development
trends and State Department of Public Health guidelines.
The study area was segregated into three pressure zones based upon
topography and the development of an orderly water service network.
The pressure zones are as listed in Table III. Zone I is served by a
hydraulic gradient elevation of 349 feet and the elevations within
Zone I vary from an elevation of 10 to 150 feet and can be connected
with the proposed zone north and east of El Camino Real. Zone II is
served by a hydraulic gradient elevation of 430 feet and the elevations
of the 1 and served by this water are from 150 feet to 250 feet.
Zone III is served by a hydraulic gradient of 550 feet.
Pressure zones II and III will not have any local elevated storage
due to the lack of reservoir sites of sufficient elevation. Water
service will be sustained by high pressure water from the 27-inch
main in Palomar Airport Road as shown on "Exhibit A.11 Added sources
of emergency supply to Zone II and I II can come from the existing
20-i nch 1 i ne in El Cami no Rea 1 , fed by Squires Dam with a hydraulic
grade of 490 feet (working elevation).
"Exhibit A11 indicates a water system to serve the study area for Zones
I, II, and III without the need for any pump stations. This system
will provide the City with approximately 1,000 gpm near Reservoir
11 E.11 If the 10-inch line across the northern portion of the study

area remains it can furnish water to the City as it presently does.
If this line needs to be replaced, the City needs could be incorporated
in the new system on the basis that all the City requirements come
from the existing 20-inch line in El Camino Real.
The minimum size and number of arterial mains and loops are shown on
"Exhibit A." The size of the mains and the spacing of the loops de-
pends entirely on localized demand and fire flows. Since fire flows
are expected to vary from a minimum of 1,750 gallons per minute in the
residential area to a maximum of 4,000 gallons per minute in the
commercial and industrial areas, the minimum line size that is
proposed for arterial mains is 10-inches.
The type of structures proposed for construction are unknown; however,
we project there will be normal single-family residential construction
and condominiums with no more than two stories and meeting Fire Depart-
ment requirements for the fire flows listed for each density and land
use as shown on the Land Use Plan. If, in the future, high-rise con-
struction or any other high-density construction is allowed, the fire
flows and demands may change substantially and pipeline capacity into
those areas would have to be re-evaluated at the time with respect to
the adequacy of the sizing of the pipe and available supply. This is
also the case within industrial and commercial areas. If high water
use industrial and commercial establishments are allowed then there
may be a requirement for on-site storage or some other means to satisfy
peak water demands as well as fire flow requirements.

VI. STORAGE REQUIREMENTS
The study area has been divided into three pressure zones as shown on
"Exhibit A." There are no reservoirs in the area and elevations will
allow only storage for Zone I within the study area. Due to the high
demands during the peak hour and for fire flow, especially for a school
site and high density residential areas (3,000 gpm), it is necessary
that storage be constructed near Evans Point to provide for a balanced
economical system.
The basic arterial system for the District was designed on the basis
of the maximum 24-hour demand and, therefore, the added flows for
the peak hour and fire flows must come from storage reservoirs. We
have calculated the peak hour requirements as 30% of the maximum
24-hour consumption. The fire flow rates are those set by the Fire
Marshal of the City of Carlsbad and the storage requirements follow
the guidelines as set forth in the "Grading Schedule for Municipal Fire
Protection" printed in 1974 by the Insurance Services Office -New
York. The required duration for Fire Flow Chart is included as
Table III.
The maximum fire flow required in Zone I is 3,000 gallons per minute
for a duration of three hours. This is the maximum requirement for
schools and RMH residential zoning. The minimum storage requirements
for Zone I are as follows:
Fire Flow (3,000 gpm for 3 hours)
Peak Hour (1,783 gpm for 24 hours x 0.3)
0.54 million gallons
0.73 million gallons
which requires a storage of 1.27 million gallons. With an area this
-12-
C
C
C
C
C
C
size it may be desirable to have a reserve that will provide one maxi-
mum 24-hour period which for this Zone I would require a total of
2.4 million gallons. Since Zone I can be fed directly from Squires
Dam the total 2.4 million gallon storage would not be required, so,
therefore, a 1.50 million gallon storage reservoir is recommended.
Zone II and III cannot be provided with storage in the study area. The
required storage for Zone II would be 0.96 million gallons for a fire
flow of 4,000 gallons per minute for a four hour duration and peak hour
requirement of 0.68 million gallons (1,575 gpm x 24 hours x 0.3). The
total of these requirements is 1.64 million gallons and a desirable
storage requirement of one maximum 24-hour day would be 2.3 million
gallons. Any storage for Zone II would be fed through Zone III and
the same fire flow storage could be utilized. Zone III would require
an additional peak hour requirement of 0.96 million gallons (2,219
gpm x 24 hours x 0.3). One maximum day storage for Zone III would
equal 3.2 m.g. Therefore, a minimum storage for Zone II and III
would be 2.6 m.g. The total maximum day storage for Zones II and
III would be 5.5 m.g. It is reconmended that 2.6 m.g. of storage be
provided for this area as the proposed plan provides a means of
transmitting low pressure emergency water from Squires Dam. Any
storage constructed in the foothills to the east should also include
storage for the area south of Palomar Airport Road and east of El
Camino Real.

peak hour. The main pipeline system was designed for maximum day
flow, so this storage cannot come from Squires Dam without the con-

VII. SUMMARY AND CONCLUSIONS
This engineering feasibility study is a straight-forward evaluation of
the public water service requirements for a well-defined geographical
area that has an established land-use plan, but some altering situa-
tions. With accelerated activity in the development of the industrial
area around the airport this study is essential from the standpoint of
public utility planning of the total area.
Overall, the study program has generated a detailed water system lay-
out capable of serving a predicted population of 6,500, the airport,
a major park, and 840 acres of industry. This system provides water
service at practical pressure ranges and in sufficient volume of
water for domestic, commercial, industrial, and open space uses. In
addition to delineating specific sectors with their water main size
and location requirements, the important feature of adequate elevated
storage for peak and fire flows is set forth in detail •
The source of water supply of the total study area was analyzed as
coming from the 27-i nch line in Palomar Airport Road. Prior
studies indicate that the proposed supply from Squires Dam and its
existing and proposed water system would utilize all of the capacity
of that system. Future plans will require the installation of a
larger pipeline in Palomar Airport Road to serve the area. Further
studies are necessary in the future to make these determi nat i ans.
The proposed system is based upon preliminary site plans and present
development of the area and possible future development trends. Due

to the lack of definitive planning in the proposed park area and the
residential areas in the north and west portions of the study area,
only generalized piping systems can be proposed at this time. Future
reviews will be necessary to blend this proposed plan into future
development phases. The proposed concept will provide several alter-
nate means of construction depending on how deve 1 opment proceeds in
the area.
The basic plan was developed utilizing the existing 16-inch line north
of Palomar Airport, realizing that portions of this line may have to
be replaced to facilitate the industrial development of the area.
This line can provide the initial water into the area but some pres-
sure reduction may be required as the hydraulic gradient is 660
feet. The proposed 18-inch line north of the existing 16-inch line
wi 11 be needed to supply water to meet the high peak hour needs
which are very simi 1 ar to the maximum day pl us fire fl ow for the
total area. This is also of sufficient size to serve the higher
elevations of Evans Point and fill a proposed 1.5 million gallon
reservoir in that general area.
Added lines are needed to serve the airport to upgrade fireflow to the
area. It is recommended a 12-inch line or equivalent be extended
through the airport and connected to the proposed street at the
westerly end of the airport. This is shown on Exhibit 11A11 with a
10-inch line paralleling the existing 10-inch line. It is also
recommended that another connection to the existing 12-i nch 1 i ne be
made at Yarrow Drive. Actual alignment of the proposed lines will
-16-

L.

,. .. .. .. .. -
depend on future development in this area and should receive careful
review by the Fire Marshal.
The total study was based on the assumption that existing and proposed
waterlines in El Camino Real (north of the 27-inch line to Squires Dam)
and Palomar Airport Road will not have excess water to supply the
area. This assumption is based on the previous studies made in the
adjacent areas which utilize the full capacity of the existing and
proposed lines in these areas and proposed plans calling for the con-
nection to these systems to help reinforce all of these areas.
Once definite plans have been established in all of these areas it
wi 11 be very advi sab 1 e to make an integrated study of the tot a 1
Costa Real Water System to determine the ultimate needs of the Dis-
trict. In the past segmented developments in different areas have
resulted in separate master plan studies and it will soon be timely
to coordinate a review of all of these plans with updated development
plans.
A minimum storage of 2.6 million gallons is required to the east of
the study area at higher elevations in order to provide the necessary
fire flow and peak hour requirements. This storage should be combined
with the requirements for Zone III (260' -384' elevation) south of
Palomar Airport Road and the area east of El Camino Real. Most of
these other areas will need to provide one maximum day of storage as
they cannot be served by Squires Dam.

After the customary review, modification, and formal adoption of the
feasibility study, the challenge of implementation of the plan will be
tied closely to the current development around the airport. As plans
develop for the regional park revisions may be made to the proposed
system. There must be a periodic review of the study area and
updating of this report. Depending upon the discipline of the land-
use control agency and other factors, land use designation may change.
We recommend a review not more than five years from now .
This study did not include any use of non-potable water in the area •
If non-potable water becomes available in the future the proposed
master plan should be reviewed with possible consideration of reducing
the size of some of the potable water lines. Due to high fire flow
demands in the industrial area around the airport pipe size reductions
are likely to be minimal. An evaluation would need to be made of the
extent of non-potable water use and a close examination made of the
type of industrial and co1TYT1ercial developments proposed, as the water
demands vary greatly •
