Augmenting the Oak Frame

Live oaks were threatened by nearby construction (like this 4-story, 330,000-pound tree) were transplanted into the park's existing tree perimeter.

Project Statement

Waterloo Park is the ﬁrst phase of the public-private joint venture to ambitiously transform the blighted Waller Creek into a 1.5-mile-long greenway and chain of parks that connect East Austin and the downtown. Waterloo Park was originally prone to severe ﬂooding and overuse during community events before being identiﬁed as the site for a ﬂoodwater bypass tunnel inlet —infrastructure that removes 28 acres from the ﬂoodplain downstream. The redevelopment of the park is the tip of the spear for the future greenway, deﬁning a language for the entire park system and creating a public space spectacle out of the co-location of this ﬂood infrastructure, a performance venue, and a robust native landscape rarely seen in Austin parks.

Project Narrative

Pushing Infrastructural Boundaries

The City’s investment in an underground ﬂood control tunnel prompted the challenge for a new conservancy to guide Waller Creek’s reinvention as an armature for the rapidly developing area now removed from the creek’s ﬂoodplain. While the core of Waterloo Park was devastated by the construction of this ﬂood control infrastructure, the park’s redesign leverages its presence with the tactical addition of a 400-foot-long post-tensioned beam on which to restore lost park area. This structural addition allows park program to reclaim the center of this community-oriented space and frees the design to invent unique solutions to accessibility, programming, and placemaking.

Integrating a Catalytic Program

Sandwiched between a view corridor to the state capitol dome and the site’s ﬂood plain elevation, the project integrates a state-of-the-art performance venue into the cross section of the site. Venues such as this often struggle to be economically and operationally viable and tend to overwhelm the sites in which they sit. Here, a “park ﬁrst” philosophy governed the design to avoid creating a dead space in the park and to minimize its impact on site experience for daily park users. While the lattice-like canopy over the stage signals park entry, the rest of the 25,000 square-foot facility is invisible from most points in the park as it is stepped down from the street elevation and its roof is covered in landscape and terraces. This conﬁguration is a ﬁrst-of-its-kind for a venue of this scale, with the back-of-house roof also serving as the public entrance to the venue. Complimenting the national acts that visit the park and its audiences, an almost equal number of community-based events utilize the facility to bring the community into the park for yoga, dance classes, art installations, and the return of cultural festivals to Waterloo Park.

Cultivating the Relationship of Planting and Program in a Park

The existing oaks that survived the tunnel inlet construction are augmented by large oak transplants from adjacent development sites to form a thick frame around the park perimeter. Surrounding the central lawn that anchors the venue, the rest of the park landscape is formed as a series of landscape “eddies” that choreograph slow meanders from the oak frame into the park. The dramatic topography, the range of pathway and seating types, and the unique vantage points built atop the ﬂood infrastructure a=ord a highly eclectic collection of garden-like spaces. Each of these spaces unfold into one another when walking through the park: a Hill Country garden, grassy rain gardens lined with palo verde, a wood deck carefully installed under a pair of existing oaks, a play area organized around an in-grade slide set into an embankment of stone scrambles, a small plaza shrouded in desert willow, a perched wetland terrace with an emergent cypress edge. Water drawn from the bypass tunnel emerges from a newly constructed seep at the southeast corner of the site along a reinvented creek bed lined with caliche blocks, forming the headwater spring to herald the downtown reach of creek and its forthcoming trail system. The unifying oak canopy around the park is juxtaposed with a rich tapestry of ground plane plantings composed of 132 species. Ninety-ﬁve percent of the park’s plant species are native to central Texas, reducing irrigation needs and providing substantial habitat for native pollinators.
