As Houston’s Downtown has developed and expanded over many decades, public green space has been increasingly constrained by several interstate routes: primarily I-59, -45, and -69. These thoroughfares, while essential for commuters, have left little room for workers and nearby residents to enjoy unimpeded access to their locale’s adjacent trailways and bayous, and the benefits of a temperate, if flood-prone, climate.
Working in concert with Houston Downtown Management District, traffic engineers at Walter P. Moore, and major stakeholder groups, SWA brought a fresh perspective to TxDOT’s desire to improve the highway system, envisioning new ways to realign existing routes and in some cases, to move them underground – freeing up the city surface for cap parks and additional connections to the firm’s ongoing work on local bayou trail systems. SWA proposed consolidating the pathways of I-45 with I-69, an approach which removes existing elevated infrastructure, partially relocates it underground, and replaces it with an at-grade parkway that reconnects adjacent districts along the roadway and bayous. This parkway feeds directly into the grid of the downtown streets.
Being located square in the middle of North America’s “sun belt,” Houston, TX is ripe for adaptive, climate-friendly, and civic-minded interventions in this vein. The Houston Green Loop, an outcome of the firm’s earlier planning work, builds on these ongoing efforts to establish a Downtown “girdled” not by freeways, but by open space systems – serving both commuters and bordering communities who had been previously cut off from vital local connections and vibrant ecology. Proposed amenities along the Green Loop incorporate unique, pedestrian-scale experiences that offer meaningful exchanges among neighborhoods and urban districts. The vision reimagines the “civic commons” with trails, running paths, restoration of a historic bridge, and detention ponds to further the project’s resiliency goals.
Exemplifying the vision that landscape architects can bring to urban environments, the careful repositioning, demolition, and consolidation of Downtown Houston’s major rights-of-way paves the way to a more resilient future for cities worldwide.
Shunde New City
The Pearl River Delta is the second largest bird migration delta and estuary in Southeast Asia. Preserving and restoring bird and wildlife corridors while also providing regional connectivity, transportation, and development options is at the pinnacle of today’s development challenges. In the Shunde New City Plan, urban development and nature are integra...
Bray's Bayou
Stretching 35 miles from the mouth of the Houston Ship Channel westward through residential, commercial and institutional developments, Brays Bayou is one of the most important waterways in Harris County, and a critical link in the area’s watershed. The $450-million project was first established in the early 2000s, with the goal of mitigatin...
TxDOT Green Ribbon Project
The Green Ribbon establishes strategies for corridor aesthetics and landscape enhancements along Texas highways surrounding Houston. This plan addresses existing infrastructure and future expansion needs of the growing urban area.
The project focuses on intensive landscape plantings and architectural treatments, improving aesthetics while addressing air...
Hunter's Point South Waterfront Park
Hunter’s Point South Waterfront Park was envisioned as an international model of urban ecology and a world laboratory for innovative sustainable thinking. The project is a collaboration between Thomas Balsley Associates and WEISS/MANFREDI for the open space and park design with ARUP as the prime consultant and infrastructure designer.
