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.

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.
