Riley, Assistant City Manager DATE: November 21, 2006 (CC Meeting of 12/6/06) 9. E. (v,,'1-, . 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 Honorable City Council December 6, 2006 Page 2 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. STAFF RECOMMENDATION Approve Final Report on Schematic Design for Ruben Castro Human Services Center.

HMC ARCHITECTS ArchitectureoPlanningo Interior Design 766 East Colorado Blvd. Suite 200 Pasadena, California 91101 Tel: 626. 535.0500 Fax: 626. 535.0510 October 13, 2006 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. Ruben Castro Human Services Center Moorpark, Ca. Plant Materials — Neighborhood Integration A majority of the plant palette is found around the adjacent properties and helps to integrate the new landscape into its surroundings. Structural Design Features Scope of Work The scope of work consists of three (3) buildings as follows: • Building "A" — Clinicas • Building "B" — Catholic Charities • Building "C" — Retail Spaces And covered walks between buildings. General Structural design and analysis of these new buildings for resisting vertical and lateral (seismic and wind) loadings will be in accordance with 2001 Edition of the California Building Code. Structural System The new buildings will consist of the following: Foundation — Conventional spread footing for column and continuous grade beam for braced frame. First Floor — Conventional concrete slab on grade. Roof Framing — 1 '/2" deep metal deck supported by steel purlins, beams and columns. Lateral System — Steel concentric braced frames.

A 4' x 8' plywood backboard and outlets will be provided in the Main Telephone Room. Lighting Title 24 calculations will be coordinated with the Lighting Design to comply with the requirements including switching, automatic shut -off, overrides, daylight area controls, and allowed lighting power. Low Voltage Systems (Fire Alarm, Telephone, Data, Security, etc.) Electrical drawings will specify empty conduits, stub -outs, outlet boxes as required by the Low Voltage vendors. In addition, power to the Low Voltage equipment will be specified as required. Ruben Castro Human Services Center Moorpark, Ca. 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. ** Mechanical Design Features Load Calculations Building A The HVAC load requirements of the building are derived from the accepted engineering standards and estimated as follows: Description Area SF HVAC Load (Tons) First Floor 9,795 33 Building B Description Area SF HVAC Load (Tons) First Floor 8,200 28 s. #:1 -$ Ruben Castro Human Services Center Moorpark, Ca.
