Main Street Promenade
Infrastructure for Urban Life
Project Facts
| Location | Houston, Texas |
| Owner | Downtown Redevelopment |
| Size | 11 Blocks |
| Cost | $12 million |
| Status | Completed 2026 |
Overview
Walter P Moore served as prime consultant and Engineer of Record for the transformation of 11 blocks of Main Street into a pedestrian‑focused urban corridor. The project converts a former vehicular street into a promenade with new sidewalks, drainage, lighting, shade structures, and public amenities. A defining challenge was coordinating infrastructure, accessibility, and stormwater systems within a constrained corridor adjacent to active METRO light rail.
Services
Challenges
Corridor Transformation
The project required reconfiguring an existing vehicular corridor into a continuous pedestrian environment while maintaining access and functionality across multiple downtown blocks.
Transit Adjacency
Design solutions needed to safely integrate pedestrian movement alongside the active METRORail corridor without disrupting operations or visibility.
Stormwater Management
Runoff had to be controlled across varying block conditions to prevent ponding, protect adjacent infrastructure, and maintain accessibility during storm events.
Urban System Integration
Sidewalks, lighting, drainage, shade structures, and public amenities had to function as a coordinated system within a constrained right‑of‑way while supporting daily use and large crowds.
Solutions
Continuous Pedestrian Alignment
The corridor was regraded with smooth transitions and consistent alignments to support accessible, intuitive movement across all 11 blocks.
Transit‑Integrated Design
Pedestrian crossings, sightlines, and clear pathway organization were coordinated with the METRORail system to maintain safe and predictable interaction between transit and pedestrians.
Distributed Drainage Strategy
Each block was designed with tailored drainage approaches that capture runoff across the corridor, reduce ponding, and direct water away from buildings and transit infrastructure.
Landscape‑Based Stormwater System
Depressed green spaces and subsurface drainage systems slow, store, and filter stormwater before conveying it into the underground system.
Integrated Streetscape Elements
Lighting, shade structures, signage, and barriers were coordinated with civil systems to support safety, comfort, and wayfinding without interrupting circulation.
Results
Connected Urban Corridor
The project delivers a continuous pedestrian spine that improves connectivity across downtown and supports movement between key destinations.
Safe Transit Interface
Integrated design strategies provide clear separation and visibility between pedestrians and rail operations, supporting safe day‑to‑day use.
Reliable Stormwater Performance
Distributed drainage and landscape systems reduce ponding, slow runoff, and improve stormwater quality before it enters the city system.
Adaptable Public Realm
The corridor supports both everyday pedestrian use and higher‑volume conditions through clear organization, accessibility, and flexible public space.
Improved Comfort and Usability
Shade, amenities, and integrated systems enhance the pedestrian experience while maintaining long‑term durability and functionality.
