40 Task 5 - Preliminary Design Concepts Task 5.A Design Concept Objective: To develop an urban design concepts master plan that considers adjacent and proposed Transit Oriented Development at the SARTC, as well as the integration of the multimodal transportation services planned for the SARTC as the gateway for Orange County and its connections to the City, Region and State. Approach: A well-designed multimodal transportation center requires a thorough understanding of each transit mode and how its components function, the spatial requirements of the equipment, passenger interface, amenities to enhance the quality transit experience, pedestrian connectivity to the surrounding neighborhoods and its ultimate function as a transportation gateway for Orange County. Based upon the work efforts developed during the previous Tasks 2, 3, and 4, the IBI Group desigri team will develop alternate urban design concepts for the three alternative scenarios. We will examine three different phases of development for three planning horizons: 2014, 2020, and 2040 (as the full build out scenario). The SARTC will develop in three phases over time with the introduction of the fixed guideway system alignment and station in 2014, an increase in existing transit service for Amtrak, Metrolink, Greyhound, OCTA Bus Transit and High Speed Rail service by 2020 along with the Santa Ana Boulevard grade separation, and ultimately a vision of the SARTC 2040 and beyond. Three alternate concepts will be developed, each illustrating expansion of the SARTC site in each of the phases through 3D image simulations and visually rich concept drawings. Urban design scenarios will also be developed. These scenarios will be comprehensive in nature, identifying alternative approaches for the following: • Primary Land Use Typology and Designations: appropriate land use types (residential, commercial, civic, open space, mixed use) • Density, Building Mass and Height: appropriate density and building mass allowances for different land use designations • Urban Design Principles: Define guidelines and principles to control building placement, orientation, design, street wall treatment and other key urban design related measures • Public Realm and Place-Making Strategies: Identify opportunities for public realm improvements and place-making initiatives • Destinations • Station and Alignment Urban Design Concepts • Station platform plans, station canopies, streetscape elements, landscaping, paving and amenities • Access and Circulation to Station • Connections to green-spaces and landscape architecture • Identify catalyst sites and TOD Opportunities Deliverables: • Draft and Final Design Concept Report including Maps and Drawings capturing site design concept proposals and phased development.
