BACKGROUND
On July 21, 2004, after hearing testimony and asking a number of
questions, the City Council continued the North Park Village
Specific Plan item with the hearing open to September 15, 2004.
This continuance is consistent with the tentative review
schedule set on May 19, 2004. The September 15, 2004, Council
meeting was set for review of biology, water supply, water
quality, groundwater, and oil well issues related to the
proposed development. Per Council's request on July 21, 2004,
representatives from the Fox Canyon Groundwater Management
Agency, Santa Monica Mountains Conservancy, and Santa Monica
Mountains National Recreation Area have been invited to this
meeting. In addition, Dr. Frank DePasquale, Superintendent of
the Moorpark Unified School District, has indicated that he
would be attending the September 15, 2004, hearing to address
school issues.

DISCUSSION
Responses to Questions
Project Description
1. How many houses are in Campus Hills, Varsity Park,
Virginia Colony, and Villa del Arroyo Mobile Home Park? -
According to County Assessor records, approximately 1,550
houses, 446 condominiums, and 246 mobile homes are located
in these neighborhoods of Moorpark, for a total of 2,242
housing units. The Campus Hills and Varsity Park
neighborhoods have 1,960 housing units, the Villa del
Arroyo Mobile Home Park has 240 housing units, and
Virginia Colony has 42 housing units.
2. Is grading on the land proposed for Phases B and C
required to complete Phase A? - As part of the project
proposal, Phase A, the first five - hundred (500) houses,
would be built with balanced cut and fill of approximately
8.25 million cubic yards. One of the project design
features identified in the Mitigation Monitoring Program
is that no vegetation in the area of Phases B and C would
be removed and no land would be graded until the new
freeway interchange is fully permitted, funded, at least
fifty percent (50 %) physically complete, and not more than
twelve (12) months from expected completion.
3. What could County Supervisors approve on the site without
a SOAR vote? What potential uses would this include, and
what traffic impacts could result? What are the SOAR
voting requirements in the County? - The County SOAR
Ordinance is structured differently than the City's SOAR
Ordinance. The County SOAR Ordinance, with limited
exceptions, requires countywide voter approval of any
change to the County General Plan involving the
"Agricultural," "Open Space," or "Rural" land use map
designations, or any change to a General Plan goal or
policy related to those land use designations. The General
Plan designation for the North Park property is "Open
Space." The zoning is currently "Agricultural Exclusive ",
which allows a variety of agricultural uses, private
airfields, communications facilities, cultural
interpretive centers, residences including farmworker
housing complexes, renewable resource energy production,
festivals, filming, firewood operations, government
buildings, mineral resource development, utility

structures, farmworker community centers, parks, soil
amendment operations, and large animal veterinary
hospitals. The minimum lot size, at forty (40) acres could
allow as a potential use the construction of up to 89
residential units. It is common on these larger lots (and
permitted under existing County law) to include second
dwellings. With second dwellings, an additional 89 units
could be built for a total of 178 housing units. Using
trip generation rates from the North Park Specific Plan
EIR, an 89 -lot subdivision could generate between 850 and
1,700 daily vehicle trips, depending on how many second
dwelling units are built. This compares to 22,719 daily
trips from the proposed project, which includes
residential uses, a school, parks, commercial center,
lake, and day care center all generating vehicle trips.
Under the proposed General Plan Amendment associated with
the North Park Specific Plan, any increase in the total
number of homes would require subsequent voter approval,
making second dwellings less likely to be built.
The Board of Supervisors could consider a change of zone
for the site to "Open Space" without a change in the
General Plan, and therefore without a SOAR vote. Such a
zone change would allow a greater variety of uses,
including development of 10 -acre residential lots. The
development of the entire site with 10 -acre residential
lots could result in over 300 houses and over 300 second
dwelling units on the lots, once roads and other
infrastructure are accounted for. A 300 -lot development
could generate between 2,865 and 5,730 daily vehicle
trips, depending on how many second dwelling units are
built.
The County's Open Space zone allows all the uses permitted
in the Agricultural Exclusive zone as noted above, but it
also allows, through various permit review processes, the
following uses: equestrian centers, cemeteries, historic
repositories, colleges and universities, correctional
institutions, law enforcement facilities, composting
operations, public service /utility offices and service
yards, campgrounds, athletic fields (unlit), geothermal
spas, golf courses and /or driving ranges, motocross /off-
highway vehicle parks, periodic outdoor sporting events,
recreational vehicle parks, retreats, shooting ranges and
outdoor gun clubs, and waste handling, disposal and
,)-60 03

recycling facilities. Although most of these "open space"
uses are low trip generators, development of a mix of
these permitted uses on the project site could result in
an equal or greater trip generation than the proposed
Specific Plan, depending on the ultimate intensity of the
use. Projecting trip generation from this list of uses
would be very speculative without a specific proposal to
review.
Traffic
4. What alternatives are available for construction traffic
access? - Construction traffic consists of grading and
construction equipment deliveries, construction materials
deliveries, and grading and construction work crews
accessing the site. The only available construction access
routes to the site at this time are through Collins Drive
or Campus Park Drive. A map showing the existing
construction easement from the end of Campus Park Drive
through the Unocal property is attached (Attachment 1).
The construction of the freeway interchange and access
road would provide a third option. Improvements to the
intersection of Collins Drive and Campus Park Drive are
expected to mitigate adverse Level of Service impacts from
construction traffic, however, Mitigation Measure No. 2 in
the Traffic section of the Environmental Impact Report
(EIR) calls for a "Traffic Management and Construction
Materials Delivery Plan" prior to the issuance of a
grading permit to minimize disruption to the area. The
alternatives that could be considered in this plan include
the use of Collins Drive or Campus Park Drive, or a
combination of the two for site access (prior to
completion of the new interchange), the management of
allowable times for access (including staggering
deliveries during allowable times), and the management of
number of vehicles per day.
5. What responsibility would Moorpark College have for
mitigating traffic impacts from future increasing student
population? - The California Environmental Quality Act
(CEQA) Section 21080.09 requires a college to prepare an
EIR for a long -range development plan. The EIR must
include an analysis of effects related to changes in
enrollment levels (CEQA Guidelines Section 15081.5(b)(1)).
Moorpark College has been preparing a Master Plan for its
campus; a Draft EIR for this Master Plan is also under
Honorable City Council
September 15, 2004
Page 5
preparation. Moorpark College is the Lead Agency in the
preparation of its EIR and therefore is the Body which
would certify the EIR. If the College EIR identifies
traffic impacts in Moorpark, it is within the authority of
the College to mitigate the traffic impacts or override
the impacts through findings in the EIR certification
process. Information on the traffic impacts of the future
growth anticipated at Moorpark College and mitigation
measures needed for these impacts should be included in
this Draft EIR.
6. What funding mechanism would ensure completion of the
interchange and access road? - The applicant has proposed
the following process and funding mechanism to ensure the
completion of the interchange and access road. This
proposed process and funding mechanism should be included
in the development agreement.
DESIGN AND CONSTRUCTION REVIEW
As a privately funded improvement, the City of Moorpark,
through funds generated by North Park Village, would
assume the leadership role in permitting the improvements.
Caltrans' role in the approval, design and construction of
the interchange would be one of review, permitting and
limited oversight. Caltrans would not design or bid the
project; nor would Caltrans manage the construction of the
improvements beyond general oversight. These tasks would
be managed by the City of Moorpark, (in some instances
delegated to North Park Village by contract), and funded
by North Park Village. The process for approval of design
and construction of Moorpark College Interchange is
proposed as follows:
Project Study Report (PSR) : This initial study documents
the purpose and need for the interchange, its feasibility,
and other basic information required by Caltrans to
approve a new connection to the state highway system. A
PSR is required for a privately- funded project where the
value of construction is estimated to be over $1 million.
A critical path task, the PSR would be initiated as soon
as practical. In this case North Park Village proposes
that the PSR be initiated immediately after the SOAR
election. North Park Village would prepare the PSR subject
to review and approval by the City of Moorpark.

Honorable City Council
September 15, 2004
Page 6
Project Development Team (PDT) : Critical to the
successful processing and approval of the PSR and
subsequent tasks is the creation of a Project Development
Team (PDT) . The PDT is comprised of Caltrans staff, City
of Moorpark staff, and North Park Village technical
consultants (i.e., engineers, etc.). The PDT would be led
by an overall program manager responsible for the
processing of all elements of project approval between
Caltrans, Federal Highways, and the City of Moorpark. The
program manager and PDT would report to the City of
Moorpark. The entire effort would be funded by North Park
Village.
Cooperative Agreement: Coincident with the development
and approval of a PSR, a Cooperative Agreement would be
executed to permit the construction of a new interchange
by parties other than Caltrans. Since such an Agreement
must be between public agencies, this Agreement would need
to be between the City of Moorpark and Caltrans. The
Agreement would define the roles and responsibilities of
the parties for the design and construction of the
interchange.
Design Approval: Caltrans would review and approve the
project design, pursuant to the terms and provisions of
the Cooperative Agreement. Caltrans would not be the lead
in the design of the project. The role would be performed
by the City of Moorpark, funded by North Park Village.
Encroachment Permit: An encroachment permit is needed by
all privately- funded projects constructed within the
state's right -of -way. The encroachment permit process
would authorize the City of Moorpark to actually construct
the interchange. Because this can be a complicated and
potentially lengthy process, it should be managed by the
PDT, as discussed above. As the leader of the PDT, the
City of Moorpark would exercise maximum control over the
timing of the encroachment permit process.
FUNDING AND SECURING THE IMPROVEMENTS
As discussed above, it is proposed that the Moorpark
College Interchange be entirely funded by the North Park
Village project. It is proposed that prior to issuance of
the building permit' within the Property, the City and

North Park Village would form a Community Facilities
District ( "CFD ") pursuant to the Community Facilities Act
of 1982 for the construction and /or acquisition of the
Interchange and other public improvements.
Concurrent with the formation of the CFD, the City and
North Park Village would enter into a construction
management agreement whereby North Park Village would
oversee and manage the construction of the Interchange.
As a condition of the agreement, North Park Village would
be required to post performance bonds in an amount
satisfactory to the City of Moorpark. CFD bond proceeds
would be prioritized and set aside first to pay for: i)
the Interchange costs; and ii) other authorized
improvements.
Prior to issuance of the building permit2 within North
Park Village, the CFD would issue bonds in an amount
sufficient to fund the cost of constructing the
Interchange and the other authorized improvements and
fees.
If, at the time that CFD bonds are issued, North Park
Village does not have sufficient value to meet a value to
lien ratio as stated in the City's land- secured financing
policy, North Park Village would deposit cash in an escrow
account or post an irrevocable letter of credit for the
deficiency as a condition of bond closing. If North Park
Village fails to provide the required amount of cash or
letter of credit, no additional building permits would be
issued.
Upon issuance of the CFD bonds, a special fund would be
established for the expected construction costs of the
interchange. Additional CFD bond proceeds would be
deposited into a second fund and would be used for other
authorized improvements and fees. Each month, after funds
are deposited into the interchange construction fund,
monies shall be withdrawn and paid to subcontractors and
consultants for work performed relating to the
interchange, subject to typical City verification
procedures.
7. Would the SR -118 bridges over the arroyo require physical
widening to add an extra lane in each direction? - Current
2 A threshold as negotiated in the Development Agreement.
I'Y GOOO T
Honorable City Council
September 15, 2004
Page 8
plans by Caltrans for the widening of SR -118 between Tapo
Canyon Road and New Los Angeles Avenue call for either the
physical widening of the existing bridges or the addition
of new bridges. Caltrans staff initially evaluated a
potential design exception to restripe the existing
bridges with an additional lane and rejected this design.
8. What would be the process for the City to use eminent
domain to acquire land for the access road, should the
applicant be unsuccessful in acquiring the land through a
voluntary transaction? - The development agreement and /or
conditions of approval on the Tentative Tract Map for this
project would include terms and conditions for the City to
acquire property for public right -of -way should the
applicant be unable to obtain the proper easements or fee
title to the land needed for the access road between the
new freeway interchange and the specific plan site. The
Subdivision Map Act provides for local agencies to use
eminent domain authority, including authority to take
immediate possession, to acquire land for off -site public
improvements when the developer is unable to obtain
necessary title, and for the developer to pay the entire
costs associated with acquisition. The eminent domain
process includes early notification of the affected
property owner and the consideration by the City Council
of a resolution of necessity at a public hearing.
Complete procedures and regulations for the use of eminent
domain are included in Title 7 of the Code of Civil
Procedure.
9. How much additional widening on Collins Drive is required
by North Park as compared to M&M Development (the
developer /owner of the southwest corner of Collins Drive
and Campus Park Drive), would Moorpark College be
responsible for this, and could the City complete these
improvements without the North Park project? - The City
Engineer's office has estimated the widening cost to M &M
Development to be approximately $100,000. Physical
widening to Collins Drive is required from the
intersection with Campus Park Drive to the westbound SR-
118 freeway off -ramp to accommodate a median that would
prevent left turns in or out of the Campus Plaza shopping
center at its Collins Drive access. An additional $80,000
in costs is estimated to complete the improvements
identified in the North Park Specific Plan EIR. The amount
'YO00 )8
Honorable City Council

of traffic added to this intersection by the projected
increase in enrollment at Moorpark College and the
contribution by the college to this mitigation would be
determined as part of the EIR process for the Moorpark
College Master Plan.
Public Services
10. What will it cost to build a new library to have enough
books to meet library standards per capita? - Standards
adopted by the City in developing the Library facilities
fee include 1.0 square foot of library space per person, 3
books per person, 8.5 periodicals per 1,000 people, and 1
computer per 2,000 people. The current 7,000 square -foot
Moorpark Library has 48,572 books, 93 periodicals, 10
computers, and serves a population of approximately
36,271, extending beyond the City boundaries. It is
currently deficient under the City's standards by 29,271
square feet of library space, 60,241 books, 215
periodicals, and 8 computers. The cost of additional
library space to bring library space up to City standards
to serve the existing and planned population of Moorpark
and the surrounding area, without the North Park project,
is estimated at approximately $7.8 million, not including
books, periodicals, and computers.
Under the standards noted above, the North Park project
would generate a need for an additional 5,775 square feet
of library space ($1.2 million construction cost), 17,325
books, 49 periodicals, and 3 computers. Library facilities
fees generated by the issuance of building permits for the
North Park project would provide approximately $1.49
million at current rates. This amount would provide for
the needs of the development, but would not assist in
making up for the current deficit in library space.
Open Space
11. How does the acreage of proposed nature preserve in the
North Park project compare to existing preserved open
space in the City? - The following table shows natural
open space acquired from other projects in Moorpark. This
1,092 total acres does not include smaller HOA common
space lots that combine natural and graded open space such
as the open space lots in the Mountain Meadows
neighborhoods:

12. How could the site be preserved as open space and what
funding mechanisms are available from the State, or
possible Citywide assessment? - Assuring the preservation
of the site in its current condition or as a nature
preserve would require either acquisition of fee title to
the property or acquisition of a conservation easement on
the property by either a public agency or private land
conservation entity. A number of funding mechanisms for
acquisition are available. They range from budgeting
decisions of the acquiring group, whether it is a public
agency or privately- funded land trust, to special taxes by
a public agency with taxing authority (requiring a 2/3
voter approval).
13. Have any appraisals been prepared for the property? The
applicant has indicated that no appraisals have been
prepared for the property.

15. What can be done for area residents to protect them from
Valley Fever during project grading operations? Would the
City incur any liability on this issue if it approves the
project? - The applicant has provided additional
information in response to this question (Attachment 2).
16. When will the Phase 11 (Hazardous Materials) study be
completed and what will happen to the project amenities if
the mitigation is severe? - Studies of hazardous materials
on a project site include Phase I and Phase II
Investigations. Phase I Investigations are typically
performed as part of the environmental review process
associated with discretionary land use applications.
Phase II Investigations typically occur prior to
initiation of construction or grading activity.
Phase I Investigations evaluate available data concerning
historical uses of the property; including past and
current ownership; interviews of persons having historical
knowledge of the property; historical aerial photographs;
fire insurance maps; site maps and plans; title searches;
hazardous waste plans; business plans and inventories;
previous site investigation reports and real estate,
zoning, utility, topographic, and geologic maps; and site
visits to visually verify any indication of possible
hazardous material contamination discovered during the
historical review. Phase I Investigations typically
recommend further investigation and mitigation (Phase II
Investigations) should a proposed land use proceed. Such
recommendations are typically incorporated into requisite
environmental documents.
The environmental review process for North Park Village
has followed this procedure. A Phase II Investigation is
required as part of standard conditions and requirements
prior to the issuance of a grading permit. The Phase II
Investigation will conclusively determine if the prior
operation of all active and abandoned on -site oil wells
and pipelines caused any contamination of subsurface soil
or groundwater. Clean up is required in accordance with
existing laws. In the experience of the applicant it is
not foreseeable that the mitigation and remediation likely
required to complete the Phase II requirements would alter
the footprint of the proposed plan or jeopardize the
proposed amenities. Phase II mitigation usually involves
lyty��11

the removal, disposal or destruction of hazardous material
pursuant to state federation and /or county regulations.

Date: August 25, 2004 MEMORANDUM
To: Vince Daly, North Park c: Kim Kilkenny, North Park Village, LP
Village, LP
From: Eric Walther, Ph.D.
Project: 29020701
Subject: Valley Fever Assessment for North Park Village, LP
This memorandum responds to your request to assess the Valley Fever issue as related to the
North Park Village project. This assessment will briefly describe the genesis of Valley Fever and
the actions North Park Village will take to assure that its contribution to the incidence of the
disease is negligible. A brief biographical sketch of my background is at the end of the
memorandum
Valley Fever is the common name for coccidioidomycosis (pronounced kok-sid-ee-oid-oh -my-
KOH-sis), a respiratory disease caused by the fungus coccidioides immitis (pronounced kok -sid-
ee-OID-eez IMM- ih- tiss). The fungus exists as a mold in undisturbed surface ( <12 inches) soil,
especially around rodent burrows, Indian ruins, and burial grounds. The incidence of the mold is
more common after a rainy winter or spring. The name, Valley Fever, comes from the Central
Valley or San Joaquin Valley, where the affliction is most common.
Valley Fever is caused by the body's reaction to inhalation of the spores of the fungus.
Approximately 60 percent of people do not display Valley Fever symptoms after inhaling the
spores. The remainder of exposed individuals display the flu -like symptoms of Valley Fever,
which include fever (104- 105F), harsh dry cough, loss of appetite, headache, body ache, nausea,
and swollen lymph nodes. Less than one percent of infected individuals develop more serious
effects from the disseminated form that spreads from the lungs to the bones, joints, skin, liver,
kidney, brain, etc. These effects include joint swelling, limping, lameness, skin abscesses,
incoordination, seizures, pneumonia, meningitis and death.
Valley Fever is diagnosed by an antibody blood test or culture, and is treatable with oral and
injectable anti - fungal agents. No vaccine has been developed to protect individuals from
infection after exposure to the spores. Valley Fever symptoms affect 50,000 to 100,000 persons
each year in the US. Of these, 35,000 cases occur in California. Ventura County had 41 cases of
Valley Fever in 2003, none of them fatal, and none occurred in the Moorpark area.
The next part of the discussion focuses on the mechanism by which people are exposed to the
spores. Fungal spores are basically small particles with a size of a few microns (i.e., one micron
is one millionth of a meter or one thousandth of a millimeter versus 17 -180 microns for the
diameter of a human hair). These small spores can be easily released to the atmosphere by wind -
induced turbulence, and spread by wind to other locations. High winds alone can disturb soil and
release the spores, but soil disturbance makes the spores more easily entrained in wind.

Agricultural tilling is the largest regularly repeated activity that disturbs soil and releases spores.
Earthquakes (e.g., Northridge on January 17, 1994) and associated landslides are infrequent
large -scale disturbances of soil that can release large amounts of spores in a short period of time.
The Northridge earthquake was followed by an anomalously high occurrence in Ventura County
of 203 Valley Fever cases in 8 weeks, including 3 deaths.
Construction activities such as excavation and grading disturb soil, and potentially allow
entrainment of soil dust and fungal spores into the atmosphere. Highest risk individuals are
Central Valley farm workers, who are exposed for relatively long periods of time and to large
soil dust concentrations. Construction workers are also potentially exposed to large soil
concentrations for long periods of time, depending on dust control measures that may be applied
in their projects. Susceptible population subgroups are the elderly, African- Americans, Asians,
women who are pregnant in their third trimester, and those with weak immune systems.
Dust control, or lack of it, becomes the key to actual exposure of individuals to the spores.
Agricultural workers typically do not apply active dust control measures to tilling or the use of
mobile agricultural equipment (e.g., tractors, combines). Pickup trucks drive down agricultural
dirt roads with no dust control, raising large, long plumes of soil dust that travel for miles before
settling out.
Strict dust control during construction of North Park Village will protect both workers and
surrounding neighbors. North Park Village will encompass a large total area of 3,586 acres, of
which about one third (i.e., 1,131 acres) will be disturbed for the construction of 1,650 homes
and community facilities. Although excavation and grading for the construction of these homes
and facilities will disturb the soil, potential generation of fugitive dust from construction of the
project will be strictly controlled by the following comprehensive set of measures that were
adopted during the evolution of the draft and final Environmental Impact Report (EIR):
- Watering will be used frequently (at least twice daily) on soil that is being disturbed by the
movement of heavy -duty construction equipment, such as scrapers, bull dozers, graders and
compactors. Affected activities include land clearing, grubbing, scraping, excavation, land
leveling, grading, cut - and -fill operations, and demolition.
- Inactive disturbed areas (e.g., storage piles of fill dirt) will be stabilized against wind erosion
with environmentally -safe dust suppressants.
- Construction activities will be scheduled to occur upwind of active excavation, when and
where possible.
- Construction personnel will be hired from the local population, where possible, because the
local population is more likely to already have developed immunity from Valley Fever.
- Construction personnel will be provided with ventilators or masks to reduce their chance of
inhaling spores.
- The maximum speed of construction vehicles will be controlled to not exceed 25 miles per
hour.
- Clearing, grading, earthmoving or excavation operations will be suspended during periods of
high wind (i.e., greater than 25 miles per hour averaged over one hour).

Heavy -duty construction vehicles will be washed before they leave the site.
Construction mobile equipment will be kept onsite or close by to minimize fugitive and
exhaust emissions for daily mobilization.
The set of fugitive dust control measures will comply with Ventura County Air Pollution
Control District (APCD) Rule 51 (Nuisance).
The Project has committed to additional specification of these dust control measures as follows:
- Soil will be moistened to a depth of 4 inches where Valley Fever spores could be present.
- Dirt roads will be watered frequently enough to prevent visible dust plumes.
- Dump trucks and other construction vehicles exiting the site will be treated to remove soil
from their wheels before entering public streets. Example treatments include wheel bumps to
shake off the soil, and wheel washing stations at construction exits. Transition aprons
between onsite dirt roads and public streets may also be constructed and cleaned frequently
to reduce offsite transport of soil (called trackout).
- Blowers and dry rotary brushes will not be used to clear dust off paved roads onsite.
- The water trucks will include a front watering bar to reduce dust generation from their own
wheels.
Implementation of the above sets of fugitive dust control measures assure that the chance of the
public or project workers contracting Valley Fever from project activities would be reduced to
negligible.
