Avenue 44 at Coachella Valley Stormwater Channel Bridge Replacement

The Avenue 44 Bridge Replacement restored a critical east-west connection in the City of Indio following the loss of a low-water crossing during Tropical Storm Hilary in August 2023. The new structure, a 512-foot-long, 78-foot-wide bridge, is designed to provide a resilient, all-weather crossing over the Coachella Valley Stormwater Channel, improving regional mobility, public safety, and flood protection.

Harris & Associates provided full construction management services, supporting the City of Indio through complex coordination, regulatory compliance, and active construction oversight. The project required careful integration with existing flood control infrastructure while maintaining access, managing detours, and addressing environmental and stakeholder considerations.

Core Elements

As a replacement of a critical crossing within an active stormwater channel, the project presented challenges related to stakeholder coordination, utility conflicts, environmental compliance, and construction within a flood-prone corridor. Harris supported the City with proactive planning and coordination to maintain progress while addressing these constraints.

Key elements of the project included:

Construction of a 512-foot-long, 78-foot-wide bridge designed for all-weather access
Replacement of a low-water crossing vulnerable to flood damage
Coordination with Indio Water Authority (IWA), Charter/Spectrum and Frontier communication lines; Southern California Gas (SCG) line and Coachella Valley Water District (CVWD) for utility sequencing and relocations
Management of foundation construction and equipment staging within the CVWD stormwater channel
Implementation and monitoring of regional detour routes, including Avenue 45, Palo Verde Street, and Golf Center Parkway
Community outreach through a project hotline, website, and public notifications
Third-party biological and environmental compliance monitoring aligned with NEPA and CEQA requirements
Oversight of permit compliance, including agreements and certifications from resource and regulatory agencies
Paleontological monitoring services provided in coordination with the San Diego Natural History Museum

Beyond the Blueprints

The Avenue 44 Bridge Replacement is a high-visibility infrastructure project that directly affects daily travel, local businesses, and regional connectivity. Harris worked closely with the City of Indio to maintain clear communication with the public and stakeholders while managing construction in a constrained and environmentally sensitive setting.

Harris supported the City through:

Active stakeholder engagement, including coordination with residents, businesses, schools, and agencies
Management of public communications, including hotline response, website updates, and community notifications
Coordination with utility providers to resolve conflicts early and maintain construction sequencing
Monitoring and adjustment of traffic detours to maintain accessibility and minimize disruption
Oversight of environmental compliance, including biological monitoring and adherence to NEPA Environmental Commitments Record and CEQA Mitigation Monitoring and Reporting Program
Coordination of work within the stormwater channel to maintain construction progress during storm season

Through disciplined construction management, proactive coordination, and consistent stakeholder engagement, Harris helped the City of Indio deliver a resilient transportation link that strengthens regional infrastructure and supports long-term community needs.

Harris provided third-party compliance monitoring for the City. During a routine monitoring check, the Harris biological monitor noticed that the contractor was impacting Waters of the US and State outside of the approved project impact area. Harris immediately notified construction management to stop the impacts before they became excessive and worked with the regulatory agencies to ensure the project could continue on schedule and could retro-permit for the impacts. The monitors in-depth knowledge of the project and their use of GIS-based applications for field verification helped ensure that Harris could precisely third-party monitor both the biological monitoring consultant and the construction contractor to prevent major unpermitted impacts- a testament to Harris’s dedication to seeing clients through intensive compliance requirements to bring projects to a successful close.
