Yesterday, I got a chance to visit the month-old Continental Avenue Bridge, Dallas' most recent highway-to-walkway park conversion and one small piece of a larger vision for the Trinity River floodplain in the coming years. A couple of Studio Outsiders were competing for the Dallas Major-League Bocce championship title at literally the highest level of competition in their sport in the DFW area, so Charlie and I decided to come cheer them on and see a new landscape project while we were at it.

Designed by Wallace Roberts and Todd, the formerly four-lane vehicular bridge is now a linear pedestrian plaza, dotted with active and passive areas for chess, water play, play structures, relaxation, bicycling, running, and of course bocce ball.

From WRT:

“[We] helped guide the preparation of multiple concepts for the bridge, leading to a preferred design consisting of a raised promenade flanked by bicycle and transit lanes. The promenade contains tilted planes, green walls, movable seating, and special lighting in support of vendors as well as gatherings and performances.”

The park not only serves as a great pedestrian amenity close to downtown, but also as a great place to view and explore the Trinity River Basin including levee trails and the Calatrava Bridge. As you'll see below, it's also a perfect place to watch incoming storms!

Ellen and Allison laser focused on winning the 'ship - and YES, they made the finals.

Bocce is a sport of precision. No messing around.

The Continental Bridge runs just parallel to the often polarizing but undeniably striking Calatrava bridge.

p.s. - apparently Allison and Ellen's team have also won a "regional" championship in oak cliff and proudly display their trophy at work. So here it is, in all its glory. May we all be half as successful as you guys at one point in our lives.

Oakbrook Center first opened its doors in 1962 and quickly became a regional shopping destination for the Chicago metropolitan area. The mall, located in a first ring suburb of Chicago called Oak Brook, offered a unique shopping experience in an outdoor, open-air environment. Original designs for the mall played on this idea by conceptualizing the mall as a garden, with water features within the garden a primary component of the experience of the place.

Oakbrook is the second-largest retail destination in the Chicago area, so it was an easy decision for Chicago-based development company General Growth Properties to invest in the redesign of the shopping center. In 2011, GGP engaged Omniplan Architects and Studio Outside in that task: to take the strong points of the existing shopping center and re-envision them through total renovation of the exterior space.

The studio team used an elegant palette of materials to revitalize and upgrade the aging facility while using many of the existing large specimen trees as focal points of the landscape design. The largest task that faced the design team was to re-imagine the shopping center’s well-known water features. Studio Outside began the large task by conceptualizing 5 new fountains which would run year-round for the mall. Fountain Source, a California-based fountain design firm, helped the team understand the powthe intricacies of water technology and engineering.

At the heart of the mall is perhaps the renovation project’s most celebrated amenity, the Vortex Fountain. The large, central fountain consists of a series of concentric spirals that work in harmony with water jets, lighting, and seating to create an incredible public space and focal point for the entire project. A large, central fountain had always existed in its space, but it’s tired 1960’s design was one-dimensional and did not excite shoppers.

The owner challenged the designers to create a fountain that was visually dynamic while also discouraging shoppers from directly entering the space. To do this, the fountain’s form created a space, as opposed to simply acting as an object in space. The design team sought to minimize the edge of the fountain in order to marge the fountain into the surrounding plaza space. The edge was given multiple functions; it acts as a seat wall, a planter wall, and a water container. Instead of being continuous, the wall is made up of many segments spiraling around each other. This makes it hard to define where it begins and where it ends. At its lowest point, the fountain is only 18” deep and spirals down to this point from the elevation of the plaza surrounding it.

The sculptural water feature plays a significant role in the visitor’s experience of the fountain. Fountain Source created very dynamic water sequencing to engage visitors. Vertical jets emphasize the spiraling form of the fountain and draw the visitor’s eye down to a large central array, a composition pulsing with over 4,000 gallons of water per minute. This is enough volume to fill a typical backyard swimming pool in less than five minutes.

What a visitor will never see is the impressive pump and computer system built by Illinois-based fountain contractor Fountain Technologies and General Contractor Graycor Construction. Together, the team was able to design, engineer, and build the system that runs the fountain including: a 40,000 gallon water tank (located in the basement of the mall building next to the fountain), a highly sophisticated computer panel, over 50 Crystal Fountain nozzles and LED lights, 7 pumps, and an elaborate network of piping.
