Project Overview
Existing SR-75 Entrance
• Satellite office for CHP• Removable Barrier Machine (Zipper) storage• Caltrans storage & maintenance yard
Existing Operations
A conceptual design was prepared in 2012 with goals to:• Calm traffic• Beautify the entrance to Coronado• Maintain/Improve Caltrans/CHP operations• Design to a budget of $840k
Project History
The Project Today
• No constraints – dream!
• What does the community want to see?
• Integrate Third and Fourth Street Traffic Calming Study and CREA Design Competition Information
• Get public input for conceptual design alternatives that lead us to a final conceptual design

“UNIQUE” DEFINES US
AND SO, WE’VE ALWAYS HAD A UNIQUE GATEWAY
GETTING TO CORONADO … BEGINNING IN 1886
OVER THE YEARS, 9 PLANS TO SPAN THE BAY
BRIDGE CONSTRUCTION BEGAN 1967
WE CAN ARGUE ABOUT THE ALIGNMENT …
ALIGNMENT LARGELY DRIVEN BY HEIGHT NEEDS
1969 BRIDGE OPENING
AND WITH COMPLETION … THIS …
HISTORICALLY, ONLY 4 GATEWAYS: ACROSS THE BAY
UP THE STRAND
FLY INTO CORONADO’S RUNWAY
NORTH ISLANDNORTH ISLAND
LAND ON THE BEACH
CONTRAST THAT WITH SAN DIEGO’S GATEWAYS
BUT NOW A PRIMARY GATEWAY
WE ATTRACT A LOT OF VISITORS
BUT CORONADO RESIDENTS PASS THIS WAY MUCH MORE OFTEN
AND ARE SURE TO WANT SOMETHING MORE ATTRACTIVE
… AND (HISTORICALLY) UNIQUE

Creating a Gateway
Vision Coding Implementation
Establish goals and expectations
Define standards and guidelines
Design and funding
Approx. 2,000 linear feet from Orange Ave. to Glorietta Blvd.(Average Speed 35 mph – 52 seconds Travel Time)
Approx. 2,000 linear feet from Glorietta Blvd. to Coronado Bridge(Average Speed = 60 mph – 28 seconds Travel Time)
The Wing
The Challenge is toTransition High Vehicle Speed and Volumes of
Freeway Cars into a Network of Neighborhood Streets.
Roundabout Boulevard GatewayPotential Treatments:
The ‘Roundabout’Modern roundabouts are the safest, cheapest, and most aesthetic form of traffic control. This deflection encourages slow traffic speeds, but allows for free flowing movement.
The central island can vary in shape from a circle to a “square-a-bout,” ellipses, and peanut shapes, and create a gateway transition between distinct areas.

The central island can vary in shape from a circle to a “square-a-bout,” ellipses, and peanut shapes, and create a gateway transition between distinct areas.
The ‘Boulevard’Separate very large streets into parallel urban realms, buffering the edge from the high-speed throughway by means of multi-way frontage roads.
Medians + landscape + lighting create a narrowed ‘gateway’ effect.
Opportunities for traffic calming mid-block and at intersections.
Careful attention is necessary to design for Boulevard transitions at the intersections as these can be confusing.
The medians provide spaces for signage, public sculpture, which limits space for civic/accessible buildings to being along the frontage roads.
Before
After
The ‘Gateway’A point or space of entry.
A structural element which marks the entrance or threshold of one district to another and located on the ‘edge’ of the districts.
A portal connecting one outdoor space with another. Gates have a range of material, shape, detail and opacity, depending on the degree of change to be achieved.
Landscape elements, such as a colonnade or grouping of trees can create a gate feature.
Symbolic Structures and Buildings must Occupy the Best Sites of the City
with the Highest Visibility
Architecture Sculpture Signage
‘Architecture’While complimentary, architecture is not sculpture. The tectonic articulation, a type of structure, of structural stability, function, and beauty.
The visual configuration of a building derived from materials and methods of its construction.
The structures may be organically, mechanically repetitive (colonnades), or classically composed (towers).
The structures may serve as visual monuments, focal points, observation decks, memorials, and/or aspiration expressions of a time, place, people.
‘Sculpture’Three-dimensional visual art, with materials being processed, such as carved (materials removed) or modeled (materials added), or free-form of materials and process.
Gateway sculptures tend to be symbolic statements, iconic monuments, memorials, and visuals. And, landscape features may serve as ‘sculptural’ elements.
‘Signage’The graphic technique of imparting verbal and symbolic information, especially when applied to a building or structure. Four types are:- Highway signs that are independent of a building, standardized, and seen from a distance at high speed;
- Traffic signs and signals standardized by speed/perceptions;
- Signage that is applied perpendicular to a building façade to be seen by those passing by;
- Signage that is applied directly to a building.

Community Input: What have we heard so far?
Tear the whole plaza down and start from scratch
The wing is mid-century and should be preserved or used as a framework
Add colorful landscaping/xeriscaping
Add seasonal flags and lighting
Add pedestrian access over the plaza
Create a welcome or visitors center
Have signage the last 1/4 mile of the bridge slowing people down
Remodel in the hotel del architecture style or early California mission style
Highlight the history of Coronado
Remove the extra lanes and add green space
