Project Overview

• 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

Coronado Gateway Context

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 – 40 seconds Travel Time)

Approx. 2,000 linear feet from Glorietta Blvd. to Coronado Bridge(Average Speed = 50 mph – 27 seconds Travel Time)

History

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 at intersections. Users approach the circle, slow down and/or yield to oncoming traffic. 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.

These are an opportunity to reduce the number of vehicle lanes due to increased capacity / lower speeds, which reduces delay, travel times and vehicle queuing lengths.

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.

These are an opportunity to reduce the number of vehicle lanes due to increased capacity / lower speeds, which reduces delay, travel times and vehicle queuing lengths.

The ‘Roundabout’

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.

CREA Design Competition

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 used as a framework

Add colorful landscaping/xeriscaping

Add seasonal flags and lighting

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
