ARCHITECTURE

Overview The project is the reconfiguration, renovation, and modernization of the existing Youth Guidance Center (YGC) located at 3030 North Hesperian, Santa Ana, California 92706, into the new use as an Adult Re- Entry Center, which provides supportive housing and services for adults transitioning out of jail back into the community. The project's vision is to promote hope and motivation for improving life quality and transformation for a better future. The intent is to address the immediate needs of those coming out of custody or involved in the criminal justice system. This is not meant to be a homeless shelter or detox.

The facility will offer short-term housing for stabilization, and pending placement such as for hard-to-place individuals will be available to use until linked to other resources and services. Emphasis will be on coordination of care, basic life and social skills, emotional freedom, and other programs to be determined based on individual needs. It will include counseling for individuals who need to continue after being stabilized. Onsite vocational hands-on and virtual training, certification programs, job readiness services, job-specific training, and onsite recruitment process.

The existing building was built in 1969 and the site consists of a total of five octagon pods, a stand-alone Gym building, and outdoor landscape and field areas. The existing facility is partially occupied by juveniles in custody who will be relocated to the new Youth Transition Center (YTC) currently planned for the OC Juvenile Hall campus once it is completed. OCPW anticipates design and construction services for the Adult Re-Entry Center to begin immediately and the renovation of the center to be planned and constructed in phases. The current project will be Phase 1.

Phase-1 scope of work includes remodeling and tenant improvements of the two westerly pods at approximately 18,500 square feet net area with the addition of a stand-alone new elevator structure for accessibility compliance. Interior T.I. wall construction will consist of steel stud walls with sound insulation blankets. Ground level existing exterior doors and windows are proposed to be removed and replaced with new storefront glazing and doors at +8’-0” A.F.F. Second level existing exterior windows will be removed for new enlarged openable windows in the living units. The ground floor ceilings will be a combination of T-grid ceiling systems with lay-in acoustical ceiling tiles, and hard lid gypsum board ceilings in designated restroom/shower and storage areas. The second level central pod and common living areas will be open to the structure with exposed mechanical ducts and decorative suspended ceilings. Interior doors to be wood with stained finish. Provide interior glass wall systems as shown on floor plans.

INTERIOR FINISHES

Overview The interior design will provide connections to the outdoors using a nature inspired color palette, varied materials, organic patterns, effective acoustics, and natural light to provide a place of healing and transformation where everyone can thrive. These elements have been shown to reduce anger, stress, anxiety, and depression and are key to creating an environment that feels calming and inviting. As we have learned from the Healthcare industry, there is growing evidence that a built environment can have a significant impact on a person’s feelings, behavior, and performance. Finishes will focus on durability and cleanability, while group areas will have softer finishes introduced like carpet and acoustic panels to enhance comfort, friendships, and a sense of home.

All products will have a record of abuse resistance, weather resistance and the ability to be maintained with minimal resources throughout the life of the facility. Materials and finishes will be specified which are appropriate for the intended use of the room or area, are highly durable, and are easy to clean, and reduce required maintenance. Floor finishes will be selected to effectively endure the anticipated traffic in each area, while patterns and accents will provide a sense of wayfinding where applicable. Corner Guards will be provided at high traffic corridors and outside of rooms that have equipment movement or storage. Highly durable tile will be utilized in restrooms and wainscots.

See the architectural narrative for ceilings, doors, frames, and hardware.

Structural System Overview Structural services proposed are for the first phase of tenant improvement, repurposing the existing 65,250 SF Youth Guidance Center for use as an Adult Re-Entry Facility. The existing, two-story Youth Guidance Center is comprised of (5) seismically-connected octagonal-shaped “pods” interconnected at the second floor and roof by structural steel framing. Phase 1 of the proposed renovation will focus on approximately 18,700 SF of the two western-most pods and partial improvement of spaces bordering the west and south sides of the middle pod. Renovations to the three remaining pods will be considered in future phases.

Structural scope for Phase 1 will provide support for the proposed architectural project design, which includes a new elevator tower, new rooftop skylights, relocation and replacement of existing rooftop mechanical units, modifications to the existing exterior walls at the second floor, plus new exterior walls at first floor, revised partition wall and ceiling layouts throughout.

Based on preliminary assessments of the project site, it has been determined that the project site resides within a United States Geological Survey (USGS) seismic hazards zone due to potential soil liquefaction. In consideration of the existing building construction and proposed alterations to the structure, structural design will be prepared in accordance with the provisions of the 2022 California Existing Building Code (CEBC). Alterations to the existing structure will be closely coordinated with the requirements of the CEBC to avoid triggering a mandatory seismic rehabilitation. New components of the structural design will be prepared in accordance with the 2022 California Building Code (CBC), non- DSA/OSHPD Chapters.

To accommodate the Phase 1 Scope, the structural design of the elevator tower will utilize fully-grouted, specially-reinforced 8” CMU shear walls for vertical elements of the tower’s gravity and lateral force resisting systems. At the top of the CMU walls, structural steel ledgers will be anchored to the CMU to support structural steel beams and a bare-steel deck roof diaphragm. The elevator tower will be seismically-separated from the existing building at a distance sufficient to limit pressures applied to elevator pit foundations by existing building pad footings. Elevator tower foundations are to be determined, pending receipt of project geotechnical and geohazard report.

Per CEBC provisions, skylights at the roof will be calibrated at each pod to minimize the removal of each roof diaphragm to less than 10% in every direction. Additionally, new mechanical unit weights and locations will be coordinated such that the building mass increase does not exceed 10% of the original building design. Supplementary structural steel framing will be provided as required at skylights and mechanical unit locations to distribute revised structural demands. Total building mass increase will be documented on the construction documents.

Interior partition walls, new and modified exterior stud walls will utilize cold-formed steel framing, attached to the existing structure with post-installed concrete anchors at floors and supplementary cold-formed steel framing elements at the roof.

For Structural Provisions only, based on the new occupancy type of the repurposed structure, the Risk Category of the structure will be reduced from Risk Category 3 to Risk Category 2. Structures and non-structural components will be analyzed for Risk Category 2. However, if feasible, structural design will maintain the Risk Category 3 classification for flexibility in future building usage.

Page | 11

Civil Overview

The majority of the existing site outside the structure will remain unchanged. A new elevator attached to the outside of the structure and a fire line for the new fire sprinkler system, are proposed as additional upgrades for the Orange County Adult Re-Entry Center, located west of the Interstate 5, Highway 22, and Highway 57 interchange, and east of the Santa Ana River.

Existing Conditions Existing site improvements will largely remain unchanged, except for existing landscaping in the immediate area of the proposed elevator and existing surface improvements along the proposed fire line alignment.

Site Grading The existing site drainage appears to follow the same direction as the Santa Ana River, draining in a northeast to southwest direction. Any modifications to the existing surface improvements for trenching purposes will be repaired in accordance to public works’ standards. An addition of an elevator to the outside of the existing building will be set approximately at the same elevation as the existing finished floor to provide drainage away from the elevator addition and accessible access from the existing walkway.

Civil Utilities The existing domestic water mainline and sewer mainline will need to be confirmed by a Utility Master Plan, or utility survey, and are anticipated to be reused. Fire Service Water is anticipated to make a connection to the existing fire/domestic water system on the campus. The proposed connection point is located on the west side of the building and adjacent to the existing parking lot. A backflow preventer and fire department connection will be required for the structure’s proposed sprinkler system. The existing sewer lateral on the south side of the existing building may need to be relocated because the footprint of the proposed elevator is on top of the sewer lateral.

Attached is Exhibit 1, showing the location of the existing utilities from an as-built plan and the proposed utility revisions and additions.

The Dry Utility (electrical / communication / natural gas) and chilled water, proposed design, relocations, and extensions will be addressed on the Site MEP's Plans.

Stormwater Treatment Water quality treatment BMP’s or any combination of underground storage systems are not anticipated for this project.

Landscape and Irrigation System Overview

Landscape and hardscape surrounding the OC Adult Reentry Center will complement the Architectural design improvements of the existing structure, respond to the dynamic interior uses, facilitate accessible circulation, seek to extend the learning environment opportunities into the outdoor realm, encourage interaction and exploration, function and integrate with the storm water management system, and provide planting areas that complement the established horticultural program and feature low water use, campus-approved species. The landscape will be designed to meet sustainable criteria, with energy and water resource conservation as well as habitat enhancements in mind.

A high-efficiency, weather-based irrigation system connected to the existing campus potable water source will irrigate drought tolerant/low water use plant species and support the long-term success and low maintenance needs for the project site. The selection of adapted ornamental and native plants with low or very low water requirements and proven performance in public educational settings, will promote water conservation, increase habitat, and expand the educational opportunities. Soil cover in shrub planting areas will consist of gravel or wood bark mulch to meet State requirements for reducing evapotranspiration of applied irrigation water and improve site soil conditions.

A water efficient landscape design will meet or exceed the State of California’s MWELO ordinance (Model Water Efficient Landscape Ordinance). The Design Team understands that use of the Water Ordinance provides direction, guidelines, and standards that provide clear direction for development of the construction documents. Plant selection, proper hydro zoning (grouping of plants based on water needs), consideration of climate, geographical location, solar exposure, topographical conditions, and employment of an efficient irrigation system are all principles that have been applied to this project to create a sustainable landscape site.

New exterior hardscape will respond to the architectural forms and interior circulation, be designed to provide intuitive and accessible circulation, rest opportunities where applicable, and visual interest.

Wide walkways with large planters and preservation of existing trees where possible will complement the campus theming and shade the circulation and gathering spaces. Redesign of the storm water rain garden will surround the new elevator structure with the intent to remove some of the high-water use/ high maintenance turf area.

New tree locations will be coordinated with underground storm water infiltration pipes, site utilities, and interior view lanes. Root barriers will be installed at new tree locations that are within 10’ of any hardscape. Native and ornamental grasses will be planted over any storm water infiltration pipes as soil cover will be limited to a depth of no more than 3’-4’.

The plant palette will respond to the OCPW approved plant list(s) as well as include proven commercially available adapted ornamental and California native species. Plant species will be selected for safety and visibility, educational value, water conservation, and the comfort and sensory enrichment of the users. The form and layout of plants will aid in the surveillance of the site by staff, encourage visual openness, while achieving aesthetic interest through color, texture, size and fragrance. Shrubs will be spaced widely to allow for full mature growth and reduce required long-term trimming and maintenance. Flowering accent trees and evergreen shade trees will be located for human comfort to offer visual relief and interest as viewed from interior spaces.
