Agenda Report BY`
To: The Honorable City Council l/
From: Kenneth C. Gilbert, Director of Public Works
Date: February 9, 2001 (Council Meeting 2- 21 -01)
Subject: Transportation Management Plan [TMP] for Las Posas
Feeder No. 3 Waterline Project by the Calleguas
Municipal Water District
OVERVIEW
Caltrans is requiring the Calleguas Municipal Water District
[Calleguas] to develop a Transportation Management Plan [TMP]
which will describe the general approach to traffic control
during the construction of the Los Posas Feeder No. 3 Project
(described below). It is the intent of Calleguas to present the
draft TMP to Caltrans for approval within the next few weeks.
This report summarizes the draft TMP and presents it to the City
Council for comment prior to submittal to Caltrans. The draft TMP
is attached as Exhibit 1.
BACKGROUND
In February of 2000, Calleguas gave a presentation to the City
Council on the Aquifer Storage and Recovery (ASR) project and the
subject water line project. That presentation included a
discussion of the anticipated traffic impacts and mitigations
being considered by Calleguas. At that time the City Council
concurred with the recommendation of City staff that, during
construction, two lanes of traffic be maintained during peak
traffic hours (9:00 a.m. to 3:00 p.m.). Calleguas has been
working to finalize plans for the management of traffic during
the construction of this project.
DISCUSSION
A. ASR Project
A brief description of the Aquifer Storage and Recovery [ASR]
Project is attached as Exhibit 2. When completed, that

Page 2
project will enable Calleguas to use underground aquifers to
place, store and recover water for use in the event of
drought, earthquakes or other water supply emergencies.
B. Los Posas Feeder No. 3 Project
The Los Posas Feeder No. 3 Project (herein "Project "] is a
part of the overall ASR Project. That Project calls for the
construction of a 72" diameter water line from a point
immediately southeast of the Spring Road Bridge, northerly to
Los Angeles Avenue, and then westerly along Los Angeles
Avenue to Grimes Canyon Road. A plan and cross - sections of
the Project are attached as Exhibit 3.
C. Project Schedule
It is the hope of Calleguas to commence construction of the
Project before the end of 2001.
D. Construction: General Description
As stated above, a plan and cross sections for the Project
are attached as Exhibit 3. A general description of the
construction efforts is as follows:
1. Although construction may be going on at more than one
location at a time, it is the general expectation of
Calleguas that the construction activities will start at
the west end of the Project and proceed easterly.
2. Traffic disruption will be limited to the construction
excavation area(s) and the approaches thereto.
3. It is anticipated that the contractor will be able to
place approximately fifty feet (501) of pipe per day.
4. The Project is expected to take approximately twelve to
fifteen (12 - 15) months to complete. It is anticipated
that the segment of the Project located east of Butter
Creek Road will take about nine (9) months to complete.
5. Except as noted below, work will consist of open
excavation and placement of the water pipe.
6. The water line will be placed at a depth of between twelve
to fifteen feet (12' - 151).
7. In order to avoid certain existing utilities and /or better
facilitate traffic flow, the water line will be installed
by boring and jacking (no excavation other than the bore
pits) at the following locations:
• Tierra Rejada Road intersection;
• Just west of Shasta Avenue; and
• Moorpark Avenue intersection.

8. From a point just west of Butter Creek Road, westerly to
Grimes Canyon Road, the waterline will be placed in an
easement located south of and parallel to the highway.
This segment of the work will not affect traffic flow.
E. Traffic Handling
The traffic handling elements of the Project are generally
described in the draft TMP (Exhibit 1) . Diagrams showing the
various Stages of the proposed Traffic Controls, are attached
as a part of Exhibit 3. Key components of the traffic
handling efforts and requirements are listed as follows:
1. Moving Construction Area: At any given date, the limits of
the Traffic Control Area will extend from the east end of
the tapered transition east of the excavation site, to the
west end of the tapered transition west of the work site.
As stated above, this Traffic Control Area will move along
the Project work limits as the work progresses.
2. Boring and Jacking: The placement of the water line along
Los Angeles Avenue east of Butter Creek Road will be done
by open excavation, except at three boring and jacking
sites noted above (Section D -7).
3. Two Lanes in Each Direction: Two lanes of traffic will be
maintained in each direction in all areas east of Tierra
Rejada Road, during the peak traffic hours. In order to
accomplish this, in certain areas additional temporary
pavement will be installed. In areas where temporary
widening is required outside of the existing street right -
of -way, temporary easements will be acquired.
4. One Lane Each Direction West of Tierra Rejada Road: The
two (2) westbound lanes will drop to one (1) lane
westbound approximately just west of Gabbert Road. The
nature of the construction in this area will require
through traffic to be reduced to one (1) lane in each
direction. [See E -7 for info on Left -turn lanes].
5. Mira Sol Drive: A westbound left -turn lane will be
provided at Mira Sol Drive. Left turn ingress and egress
from that street will be permitted during the time the
construction excavation ( which will be located on the
north side of the street) is at that location.
6. No Left Turns: Except as noted below, left turn movements
will be prohibited at all intersections during the period
the cross - street is within the Traffic Control Area.
Calleguas_0012
00004''.
Calleguas Water Line Project
February 9, 2001
Page 4
7. Left Turns: Within the Traffic Control Area, left -turn
traffic will be maintained at the following locations:
• Eastbound at Gabbert Road;
• Westbound at Tierra Rejada Road;
• Eastbound at Moorpark Avenue;
• Eastbound at Spring Road; and
• Westbound at Spring Road.
8. No Left -Turn Westbound at Moorpark Avenue: Due to the
nature of the construction requirements, it will not be
possible to provide for left -turn traffic from westbound
Los Angeles Avenue to southbound Moorpark Avenue during
the period this intersection is within the Traffic Control
area. A diagram showing the bore pits and the traffic
controls at this intersection is attached as Exhibit 4. It
is anticipated that this turning restriction will be in
place approximately eight (8) weeks.
9. Road Closures: Due to the nature of the construction and
the required traffic controls, it will be necessary to
close certain streets when the Traffic Control Area
includes those street intersections. In such case, the
affected street will be closed to all traffic at the point
where the street intersects Los Angeles Avenue. Each road
closure is expected to last a total of four (4) weeks. The
location of the required road closures are listed as
follows:
• Butter Creek Road (north end) [see Exhibit 5, pg.l);
• Flory Avenue (south end); [see Exhibit 5, Pg. 21; and
• Millard Street [see Exhibit 5, pg. 31.
10. One Westbound Lane West of Spring Road: Between Spring
Road and a point just west of Millard Street, the water
line will be located north of the centerline, due to
utility conflicts. This alignment will require the
elimination of one of the two westbound lanes. This "lane
drop" will be restricted to the hours of 9:00 a.m. to 3:00
p.m., Monday through Friday. The contractor will have the
option of constructing all or a major portion of this work
on week -ends in order to avoid the 9 -to -3 restriction.
11. Spring Road Intersection: The work and the traffic
controls at and near the Spring Road intersection is shown
on the diagrams attached as Exhibit 6 (pages 1, 2 & 3) .
Due to the nature of this work, the plans may call for
night or week -end work in order to prevent peak hour
traffic problems. Without objection, this option may be
included in the final contract and permit requirements.

Conditions will be added to the Caltrans permit designed
to minimize any adverse affects from construction noise or
night lighting.
12. Spring Road Work: The work and traffic controls for the
placement of the water line in Spring Road south of Los
Angeles Avenue, is shown on the diagram attached as
Exhibit 7. As shown on that plan, this work will require
the closure of the driveways on the west side of the
street, north of the bridge. It is estimated that this
closure will last a total of four (4) weeks.
13-Spring Road Median: The raised median in Spring Road will
be removed and reconstructed.
14-Arroyo Crossing: The water line will be placed under the
Arroyo Simi by boring and jacking. The bore pits for that
crossing will be located on private property located just
northwest and southwest of the bridge.
15. Spring Road Crossing: South of the Arroyo the water line
will cross Spring Road. This work will also be done by
boring and jacking.
F. Summary
1. Evolution of Traffic Control Plans: Calleguas has worked
hard to eliminate, minimize and /or manage a number of the
adverse traffic impacts identified in the initial project
submittal to the City and Caltrans. Those positive changes
to the plans include the following:
• Maintenance of two lanes of traffic in each direction
during peak traffic hours;
• Maintenance of left turn traffic at a number of major
intersections;
• The lengthening of left turn lanes at a number of major
intersections to better accommodate turning traffic
volumes;
• The restriction of the work hours for the reduced number
of travel lanes just west of Spring Road, to non -peak
hours only;
• The acquisition of temporary easements and the
construction of temporary pavement at certain locations
required to facilitate two travel lanes in each
direction; and
• The use of jack- and -bore construction techniques to
minimize traffic impacts at certain critical locations.

2. Inconveniences: As could be expected from a project of
this scope, construction activities will cause some
inconveniences. The more significant inconveniences
include the following:
• Road closures at three locations (See Section E -9);
• The elimination of left -turn traffic at a number of
intersections (see Section E -6);
• The closure of the Spring Road driveway to the Gateway
Plaza shopping center (see Section E -12);
• The possible use of night work for all or a portion of
the construction at and near the Spring Road
intersection (see Section E -11); and
• Reduced access to all affected commercial centers.
It should be noted that these inconveniences will be
encountered at a given location, only when the
construction and traffic controls are in place at that
location.
G. Public Relations
As discussed in the TMP (Exhibit 1), Calleguas will undertake
and manage an extensive pubic information and public
relations effort to both advise the public and to manage any
problems created by the Project.
RECOMMENDATION
Concur with the Traffic Management Plan.

Las Posas Feeder No. 3 Pipeline
Calleguas Municipal Water District
Project Description
The Las Posas Feeder No. 3 (LPF -3) pipeline project is one of the major projects included in the Aquifer
Storage and Recovery (ASR) project being developed by the Calleguas Municipal Water District
(CMWD). The ASR project uses available capacity in the underground Las Posas Basin Aquifer for
storing surplus water obtained from the Metropolitan Water District (MWD) . The surplus water is
available during the winter months when water demands are low. The stored water can then be taken
from the aquifer to supplement CMWD's water supplies during periods of drought, emergencies, or high
usage.
The LPF -3 pipeline is one of the pipelines planned to convey water to and from the Las Posas Basin
Aquifer. Other pipelines have already been constructed on both sides of the LPF -3 pipeline. LPF -3 is a
72 -inch diameter steel pipe, lined and coated with cement mortar.
The project begins at the northeast corner of the intersection of Los Angeles Avenue (SR 1 18) with
Grimes Canyon Road, connecting to an existing 60 -inch diameter waterline. Then, the pipeline turns
south and crosses Los Angeles Avenue to private property located south of Los Angeles Avenue. A 30-
foot wide permanent utility easement will be obtained for the pipeline located in private property. LPF -3
continues easterly in private property along the south right of way line of Los Angeles Avenue to a point
approximately 140 feet west of the centerline of Butter Creek Road. At this point, LPF -3 crosses into the
Los Angeles Avenue right of way.
The pipeline continues easterly inside the Los Angeles Avenue right of way to Spring Road, where it
leaves Los Angeles Avenue and continues southerly in Spring Road for 400 feet. There, the pipeline
leaves Spring Road and continues southerly in an easement west of Spring Road to the south side of the
Arroyo Simi. The pipeline crosses perpendicular to Spring Road and terminates south of the Arroyo Simi
on the east side of Spring Road at the new Moorpark Pump Station site.
Construction Methods
The pipeline crossing of Los Angeles Avenue near Grimes Canyon Road will be made in a steel casing
pipe installed by jacking. There are no lane closures associated with this crossing.
The pipeline located inside Los Angeles Avenue will be installed in a trench having a minimum depth of
approximately 12 feet. Greater trench depths are expected due to existing utilities. The trench width at
the top will be approximately 12 -feet wide. A 15 -foot wide construction zone is planned along each side
of the trench for contractor use.
Excavated material is expected to be taken off site for storage and disposal. Sand will be used for pipe
bedding and pipe zone backfill. Native excavated materials will be used for the remaining trench backfill.
Temporary asphalt paving will be placed over the trench cut as the pipeline installation is completed.
Permanent asphalt surfacing and a slurry seal will replace the temporary asphalt surfacing.

There are three locations in Los Angeles Avenue where the pipeline will be installed inside a steel casing
pipe due to existing utilities and to reduce disruptions to intersections. The intersections are at the Tierra
Rejada/Gabbert Road intersection with Los Angeles Avenue, and the intersection of Moorpark Avenue
with Los Angeles Avenue. The third casing pipe is located west of Shasta Avenue and east of Goldman
Avenue. Each steel casing pipe will be installed using jacking/boring methods. An access pit will be
constructed on each end of the casing pipe.
Pipeline appurtenances will also be installed inside Los Angeles Avenue. These appurtenances consist of
blow -off valves for draining the pipeline, air and vacuum relief valves, and one isolation valve vault. The
blow off assembly includes a drain line connected to LPF -3 and terminating in a manhole located near the
edge of asphalt or in the sidewalk area. Air and vacuum relief valves are located in or behind sidewalks
and have a valved connection directly to LPF -3. These appurtenances will be partially installed with
LPF -3, with the final installations made after LPF -3 is installed.
Public Information
Project Brochure/Handouts: CMWD will prepare and distribute a Project Brochure that contains:
Project description and purpose
Project location
Anticipated construction schedule
Contact personnel
Recommended detours
Project phone number
Web site address
This brochure will be direct mailed to businesses and residents along Los Angeles Avenue and Spring
Road, and to recipients of the project's Environmental Impact Report that are located in the project
vicinity. Handouts will be prepared announcing street closures and construction, and will be distributed
to affected residents and businesses approximately two weeks prior to construction occurring in the area.
Project Phone Number: The project phone number will contain recorded messages containing project
related information (current construction schedule, location of current work, recommended detours, and
description of future work). The project phone number will be noted on project signs and listed in news
releases. The caller will also be allowed to leave a message.
Project Web Site: The project Web site will contain project maps, construction schedules, contact
personnel and phone numbers, and recommended detour routes. The Web Site will be up -dated
periodically to account for continuing progress and pending work activities.
Media Releases: Prior to the start of construction, CMWD will release project information to local
newspapers and radio stations informing readers and listeners of the project construction activities, and
advising them to seek alternate routes. During construction, releases will include locations where
construction is currently underway, project phone number, and project web site.

Changeable Message Signs (CMS): These signs will be located at each end of Los Angeles Avenue and
on Moorpark Avenue depicting:
Traffic Delays Ahead
Use Alternate Routes
The signs will be positioned for incoming traffic to Los Angeles Avenue to observe. Up to three CMSs
will be used. Locations for these signs are shown on Figure 1.
Ground Mounted Signs (GMS): These signs will be placed on major roadways feeding into Los Angeles
Avenue. Prior to construction, the signs will show the following message:

CALL 1- 800 - XXX -XXXX FOR INFORMATION
The GMS locations are shown on Figures 1 and 2.
Incident Management
CMWD currently has a working relationship with the Ventura County Sheriff's Department. On existing
CMWD construction projects, calls are routinely made to the Sheriff's Department requesting on -site
presence to control vehicle speeds. A similar relationship and plan will be used for the LPF -3 project.

Travel Lanes: Two travel lanes in each direction will be provided during construction, except at the west
and cast ends. At the west end, from west of Butter Creek Road to west of Tierra Rejada Road, physical
constraints limit traffic to three lanes. This reach is planned to have one west bound lane and one east
bound lane with a center lane for left turns during the construction through this area. For the 1,200 -foot
long reach west of Spring Road, physical constraints also limit the travel way during the construction time
(planned from 9:00 AM to 3:00 PM) to three lanes, two west bound and one east bound (lanes can be
reversed if traffic conditions warrant a change). When the contractor is not physically at work, then
traffic control will be changed to allow two lanes in each direction. Remaining areas of construction in
Los Angeles Avenue will have two lanes in each direction.
Construction in Spring Road south of Los Angeles will also limit the travel lanes to one north bound, one
south bound and a center lane for north bound left turn traffic.
Lane Closures: Lane closures will be necessary, as shown on the traffic control drawings.
Reduced Speed Zones: Reduced speeds will be posted throughout the construction period to control
traffic and maintain a safe work zone. Speed enforcement will be furnished by the Ventura County
Sheriffs Department.
Construction Times: Construction will be limited to the times from 7:00 AM to 6:00 PM, in accordance
with City of Moorpark requests. At the east end where only three lanes of travel are open during
construction, then the construction time is reduced from 9:00 AM to 3:00 PM.
Contingency Plan
Lane Closure Termination: Termination of lane closures is not considered practical, after pipeline
construction begins. The trench width and adjacent construction access must remain available for the
contractor's use, and for safety zones between the travel lanes and work zones. Re- opening a lane would
require backfilling the excavated trench, compaction and installation of surfacing. This work will take
substantial time, eliminating the benefit of the lane re- opening.
Communication Lines: All inquiries regarding construction should be addressed to the on -site CMWD
representative (to be announced). Overall CMWD authority resides with their project manager, Mr. Steve
Fiori (805 -579- 7156). Inquiries to Caltrans should be addressed to the permit inspector, (to be
announced).

Las Posas Basin Aquifer Storage and Recovery Project
Project Background
A member agency of the Metropolitan Water District of Southern California
(Metropolitan), Calleguas Municipal Water District (Calleguas) :s located at
Metropolitan's northern boundary and is precariously dependent on State water
deliveries provided by Metropolitan through a single pipeline. As such, the district's
entire water supply is subject to a host of external forces, natural and manufactured,
ranging from drought and earthquakes to regulatory actions and water right
determinations. The inherent vulnerability of Calleguas' water supply provides the
rationale for the Las Posas Basin Aquifer Storage and Recovery (ASR) Project, which
will greatly enhance the reliability of the District's water supply.
Under the project, Calleguas, through utilization of ASR (Aquifer Storage and
Recovery) technology, will develop up to 300,000 acre feet of storage in the Lower
Aquifer System of the Las Posas Groundwater Basin. The use of surplus aquifer
capacity has been endorsed by water industry officials and environmental
organizations alike as an effective and environmentally - superior alternative to the
development of surface water reservoirs. Surface reservoir facilities require large -
scale capital and operation and maintenance costs and also hinder or preclude the
beneficial and environmental uses of the land on which they are sited. In contrast,
groundwater storage programs have relatively low capital costs, allow for the
continued use of overlying lands, and do not result in water losses or reduced water
quality due to evaporation.

Calleguas Service Area and the Las Posas Basin
ASR technology refers to the use of dual - purpose, injection /extraction groundwater
wells for the purpose of storing water and subsequently producing the stored water as
needed. The project will enable pre - delivery and storage of large volumes of State
water in the Calleguas service area during periods of availability. The stored water will
later be "recovered" (extracted) by Calleguas to meet seasonal, drought, and
emergency demands.

rn- 2 (2)
Project Profile
The Lower Aquifer System (LAS) of the Las Posas Basin provides an optimal
environment for ASR operations. A hydrogeologic study of the 18 mile -long and 4.5
mile -wide basin conducted in 1989 by Calleguas and Metropolitan suggests that
available storage capacity within the basin is on the order of 300,000 acre feet. Tnis
surplus capacity is primarily due to chronic overdraft (estimated to be in excess of
10,000 acre feet per year) that has depleted groundwater reserves in the basin.
In addition to adequate capacity, the aquifers of the LAS, the Fox Canyon and Grimes
Canyon are confined except at outcrop areas in the hills along the northern and
southern boundaries of the basin. This condition has insulated these deep aquifers
from degradation by overlying, poor quality groundwaters and potential sources of
surface contamination (i.e., agricultural operations, underground storage tanks, etc.).
Likewise, the confined nature of this aquifer system will prevent future contamination
of District stored water.

Fairview ASR Well
The project includes the installation of thirty ASR wells within an approximate nine -
square mile area in the Las Posas Basin, nearly thirty miles of large diameter pipeline
to connect the wells with existing District infrastructure, and a combined
pump /hydroelectric generation station in the City of Moorpark to deliver water to and
from the wells. Funded by Metropolitan and Calleguas, the $80 million project will be
constructed in phases over a ten year period. The Final Environmental Impact Report
for the project was certified in 1995. To date, one well, the Fairview ASR Well, is
operational and has injected several hundred acre feet of imported water into the LAS
for storage. Four other ASR wells are in the final stages of operational testing, and an
additional fourteen have been drilled, with operation scheduled for 2001.
Project facilities will enable the conveyance of water between the well field and
distribution system at a rate of 100 cubic feet per second (cfs). This rate is based on
an extraction capacity of 3.3 cfs (1,500 gallons per minute) per ASR well. Injection
rates are estimated to be slightly lower at 2.7 cfs (1,200 gallons per minute). Given
the projected extraction capacity, and assuming twelve months of around - the -clock
production, the maximum annual extraction capacity of the project would be
approximately 72,000 acre feet.
Page 2 1 5 1
Local and Regional Benefits
In addition to providing essential water storage capacity for the Calleguas service
area, the Las Posas Basin ASR project will produce numerous local and regional
benefits. From a local perspective, existing well operators in the basin (a vast majority
of which are agricultural entities) will greatly benef from project operations due to
increased groundwater levels. A three - dimensional groundwater flow simulation model
of the basin indicates that groundwater levels will rise on the order of one to three
hundred feet in response to injection operations. The increase in average groundwater
levels will result in reduced pumping lifts for existing well operators, and
consequently, reduced energy costs. As such, the principal adverse economic effect of
basin overdraft -- increased pumping costs for well operators -- will be alleviated.
On a regional level, the project offers increased operational flexibility in the event of a
severe drought or emergency. The project will afford Metropolitan the option to divert
elsewhere a portion of its State Water entitlement historically provided to Calleguas,
as Calleguas meets service area demands with water previously stored in the basin.
While unable to receive project water, other Metropolitan member agencies will derive
an indirect benefit in that additional State water would be available to their service
areas.
Moreover, the project will result in a beneficial impact to biological resources in the
Sacramento /San Joaquin Delta region due to reduced demands for State water during
low flow conditions. To the degree that stored water would be utilized to either
supplement or supplant imported deliveries, an equivalent amount of water could
remain in the Delta to aid in sustaining sensitive species and habitat during critical
periods. South -of- the -Delta storage projects, such as the Las Posas Basin ASR project,
have long been recognized by State and regional water officials as fundamental to
both ensure adequate water supplies for southern California and to abate further
deterioration of the Delta's fragile ecosystem.
Project Rationale
As clearly stated in the California Department of Water Resources' Water Plan Update
(Bulletin - 160.93), the State acknowledges that:
"... Those areas of California relying on the Delta for all or a portion of their supplies face
uncertain water supply reliability due to the unpredictable outcome of actions being taken to
protect aquatic species and water quality. Until solutions to complex Delta problems are
identified and put in place, and demand management and supply augmentation options are
implemented, many Californians will experience more frequent and severe water supply
shortages."
Calleguas considers such shortages unacceptable and, in response to the State's
troubling water supply "forecast ", is striving to implement water supply management
measures that maximize use of local resources. This strategy will reduce the region's
immoderate dependence on imported water deliveries thereby insulating the District
from circumstances beyond its control that adversely impact these sources.
Among other factors, the social and economic vitality of southern California is
contingent upon a reliable supply of high quality water. Serving as a hedge against
future water shortages, the Las Posas Basin ASR project will ensure the reliability of
Calleguas' drinking water supply for generations to come.
