Newtown Creek CSO Storage Tunnel
Subsurface investigation and multi-party coordination supporting preliminary design along one of New York's most regulated industrial corridors.
Executing subsurface investigation through a dense, high-stakes utility corridor on an active industrial waterfront.
Newtown Creek sits at the intersection of a federal Superfund site, two boroughs, and some of the most heavily regulated industrial real estate in New York.
The corridor carries a full stack of live utilities — water, sewer, gas, electric, telecom — alongside Buckeye Partners petroleum infrastructure, all running through active DOT right-of-way under DEP's environmental and regulatory oversight.
Preliminary design could not advance without clean field data — and field data could not be collected without airtight coordination across every stakeholder with standing in the corridor.
Coordinate first. Expose safely. Verify where the design demanded it.
We structured the program around stakeholder sequencing before mobilizing equipment. Every work window was pre-cleared through DEP, DOT, Buckeye Partners, and adjacent utility owners, with site-specific procedures for any activity within proximity of live infrastructure.
Soft digs and vacuum excavation handled safe exposure; test pits delivered positive verification where the design required it; geophysical tools supported markout as needed. Traffic control was engineered around the corridor's heavy truck volume and DOT restrictions — not retrofitted to them.
The result: the prime design team moved on schedule while every party in the ROW stayed protected.
Design milestones hit. No stakeholder escalations. Clean record in a high-stakes corridor.
The program continues to advance with Seylone retained as the field services backbone.
On a corridor of this regulatory complexity and public visibility, the absence of a DOT violation, a DEP escalation, or a utility strike is itself the deliverable.
The work positioned the prime design team for clean progression into the next design phase.
