BROWNSVILLE, Texas — In a move set to bolster both regional infrastructure and revenue, the Brownsville Navigation District Commission has approved a series of milestone agreements and a binding Memorandum of Understanding (MOU) with Space Exploration Technologies Corp. (SpaceX), solidifying expanded operations and deeper collaboration between the spaceflight company and the Port of Brownsville.
The comprehensive framework—outlined during a recent board meeting by Port Director and CEO William Dietrich—encompasses multi-million-dollar pipeline easements, substantial real estate leases, dirt sales, route use fees, and the groundwork for a prospective public-private partnership to construct a dedicated dock facility.
Port officials emphasized that while utility easements and land transactions are routine business for the nation’s largest land-owning port, the financial terms negotiated with SpaceX represent a uniquely lucrative outcome for the port and local taxpayers.
Under the approved terms, SpaceX is securing rights-of-way for two separate 16-inch underground natural gas pipelines and fiber-optic infrastructure designed to serve its Starbase facilities outside port boundaries.
The first authorization covers a 30-foot-wide, nearly 30,000-linear-foot easement buried at a minimum depth of four feet,alongside a temporary workspace encompassing roughly 49 acres. Financial terms include:
In a distinct departure from standard utility setups, SpaceX agreed to a monthly throughput fee structure for transporting gas intended for self-consumption. Port leadership projects the throughput arrangement alone will generate approximately $2.5 million annually over the life of the easements.
"This is an income that we are going to get," Dietrich told commissioners. "This is a normal, everyday transaction at a port of this size... [but] this actual product is going to be used for their self-consumption at this point. So we have worked in a throughput agreement... that is something that SpaceX was willing to work in with us, and that's what we've accomplished here."
Commissioners clarified during the meeting that all installation, pipeline purchasing, and construction costs will be absorbed entirely by SpaceX, at zero expense to the port. Additionally, SpaceX will maintain a $500,000 letter of credit and provide Level 5 insurance—the port’s highest coverage tier.
The approved MOU also outlines major real estate movements surrounding the port's property footprint:
To streamline industrial transit, the board approved a formal Route Use Agreement retroactive to Sept. 4, 2026. Under the agreement, SpaceX pays $19 per vehicle ($15 route fee plus a $4 port entry fee) to route commercial trucks through port property rather than public thoroughfares like State Highway 48 and Boca Chica Boulevard.
Dietrich noted that more than 30,000 SpaceX trucks had already traversed the port route, creating a substantial new revenue stream while significantly improving public roadway safety by removing heavy industrial traffic from community highways.
Looking ahead, the MOU establishes a framework for good-faith negotiations regarding a potential public-private partnership (P3) for a new dock facility and turning basin expansion. Under the proposed concept, SpaceX would help fund engineering and construction costs for loading and manufacturing infrastructure adjacent to its leased land, enabling the port to expand maritime capacity while mitigating capital risk and avoiding long federal funding delays.
"Taken together, these arrangements provide upfront payments, recurring leases, pipeline revenue, throughput charges,proceeds from earthen materials, truck fees, [and] the opportunity to acquire property at a discount," Dietrich summarized. "This is a win-win for all of us... and quite frankly, I think we're on the better side of the winners."
Following the presentation, the commission voted unanimously to authorize the port director and CEO to execute the agreements and MOU.
