SUBJECT: Consider Final Report for Schematic Design for Ruben Castro
Human Services Center
DISCUSSION:
On March 1, 2006 the City Council approved the conceptual site plan for the Ruben
Castro Human Services Center. Staff provided a status reports on June 7 and August 2,
2006 concerning proposed tenants for the facility and the proposed new building's
setbacks and visual relationship with the Police Services Center located immediately
south of the proposed site. Subsequently, staff directed HMC Architects to complete
and submit a final report on the schematic design for the project after requesting
additional modifications to the building's elevations. The Schematic Design Phase of the
project has now been completed and is presented for the City Council's approval.
REVIEW OF FACILITY CONCEPT
The Human Services Center will include space to provide medical, dental, mental
health, and other social services to the City's low and moderate income families. In April
2001, the City of Moorpark Redevelopment Agency acquired a 7.58 acre site on Spring
Road for the Police Services Center. Approximately two acres of that site have been
designated for the new Human Services Center. This parcel was acquired by the City
with Community Development Block Grant Funds for that purpose. The proposed facility
would include a 10,000 square foot medical building, a 15,000 square foot "Under -one-
Roof" Building, for non - medical services.
The Center will be landscaped in accordance with the city's adopted Landscape
Standards. To the extent economically feasible, design features and equipment will be
utilized for the buildings to insure maximum resource consumption efficiency.
The medical building setback along Spring Road is thirty -three feet, seven inches which
matches that of the CHP portion of the Police Service Center. The Under - One -Roof
building is set back sixty -four feet, ten inches to create a plaza area and to create a

diminishing architectural site line for the two facilities as drivers and pedestrians
proceed north into the downtown area. The plaza area could be utilized as a day - laborer
assembly site or as a break /rest area for center patrons and employees.
The site provides opportunities for future increased parking on the south property line
and room for expansion of the Under - One -Roof Building to the east. The existing
property being leased to Catholic Charities at the east end of the site will be developed
for parking in the final project stages to permit the agency to continue to operate there
until the new building is ready for occupancy.
A detailed Executive Narrative Report prepared by the Architect is attached which
provides detailed explanations of the recommended design concepts. A bound
Presentation Document is included as a separate submittal with your agenda materials
The Redevelopment Agency will finance the construction of the Under - One -Roof
Building, overall facility parking and site improvements with Community Development
Block Grant funds and proceeds from the agencies 2006 Series Tax Allocation Bond
Issue. The cost for this part of the project is approximately $ 6.5 million. The medical
building and tenant improvements totaling approximately $ 3.4 million will be financed
with State of California Health Mortgage Revenue Bonds in cooperation with Clinicas de
Camino Real under a separate land lease agreement with the Redevelopment Agency
that will be presented at a later date.

EXECUTIVE NARRATIVE
Project Description
The new Rubin Castro Human Services Center provides a new public
services complex to the growing needs of the local Moorpark community,
offering educational and health related counseling services in it's new two
building 25,000 SF. Campus Facility. The 2.5 acre parcel adjacent to the
recently opened police station marries the new center with a modernist view
of the California mission style.
The project includes Medical, Dental, Counseling, Educational, and
Charitable services offices and enhances the services component of the
City while creating a momentum for private business to invest and develop
in the downtown area.
Site Information
The 2.5 acre parcel, measuring approximately 260 ft. x 400 ft, rises
approximately 5 feet in elevation across the site. The design will utilize this
natural height feature to create optimum pad heights and produce the best
possible drainage flows away from the buildings.
Architectural Design Features
A number of design issues came into play in the development of the Human
Services Center that influenced the design direction.
• Integration of the design to the new police center but with more
refined elevations.
• Creating a park like setting with convenient vehicular access
• The use of the "Savings by Design" process using the "Systems
Approach" to reduce the overall building energy usage by maximizing
the efficiency of the interaction of the mechanical and lighting
systems.
• The incorporation of a possible Day Labor component to the North
West portion of the building to handle the issues of providing services
and support facilities for short term labor workers.
Ruben Castro Human Services Center
Moorpark, Ca.
• The allowance for future expansion of the planned facilities.
The design uses protected exterior circulation around a central breezeway to
reduce the heating and cooling requirements of the building while at the same time
providing shaded arcades for the interior glazing areas. Extensive and intelligent
use of landscaping will provide shading for the user and glazing. The plaza
hardscape area is broken and interspersed with landscaped areas to soften the
feel, reduce heat gain and aid in the percolation of run -off. Utilization of landscape
and lighter paving colors also will reduce heat islands and solar gain at parking and
pedestrian walkways.
Building Materials
The buildings will be primarily steel frame structures with an exterior plaster finish
with block, cast stone, steel and wood pergolas and deep recessed window
elements. Various types of stucco will be used to emphasize building elements.
The design incorporates the use of some skylighting to bring natural lighting into
some of the tenant spaces.
* *Roofs will be flat with parapets sized to conceal rooftop mounted
mechanical equipment"
Landscape Design Features
Function (Active / Passive Space)
The sites plant material blends textures and colors to create visual harmonies that
emphasize focal points, reinforce orientation, circulation, and encourage both
active and passive use.
The curving walkways through the south east green offers users the opportunity to
gather informally under deciduous trees that allow sun in the winter and shade in
the summer.
Aesthetic Value
All trees, shrubs, vines, ground covers, and lawn have been selected for their
colorful and textural aesthetic value.
The Windmill Palms, planted in a linear arrangement echo the angles of the
buildings and the surrounding linear patterned hardscape.
A variety of evergreen, deciduous, and flowering trees ensures year -round interest
and change. Flowering shrubs and perennials also add a continuous cycle of color
to the landscape.
Plant Materials — Climatic Compatibility
All plants are grouped in hydro -zones according to water needs and will be
irrigated on separate valves to ensure efficient water usage. Much of the plant
material is drought - tolerant, and is appropriate to this climate. Lawn is limited to a
small specific area designed to be used and enjoyed by the users.

Savings -by- Design
The following are two Savings -by- Design system approaches that can be
implemented into the project:
1. Daylighting
The electrical portion of daylighting consists of controlling lighting
fixtures within daylit areas. The implementation of this system will be
dependent on the architectural glazing / skylights and will be
coordinated with the architect.
2. Interior Lighting Systems
The lighting measures for interior lighting include the use of occupancy
sensors for control and high - efficiency lamps and ballasts. These items
will be implemented as coordinated with the architect.
* *Due to the small size of the building, a full blown Savings by Design
approach is not cost effective, HMC will however design the building to take
advantage of energy saving systems and products that not only incorporate
new technologies but are just the way that HMC designs buildings. HMC
remains dedicated through its Energy Resource Management approach to
provide the owner with a building that is energy efficient, conserves
resources and respects the environment. **
