Heated debate continues over proposed Inner Harbor desalination plant as council pauses final decision

The Corpus Christi City Council spent more than five hours in public comment and technical discussion on a proposed Inner Harbor seawater desalination project, but stopped short of a final vote on moving the project into the next design phase. Council members and city staff said they would continue reviewing alternatives and financial implications before taking action on construction financing.

City staff presented the design and procurement status for the Hillcrest/Inner Harbor project, describing the contract with Kiewit Infrastructure South Co. and the planned step from an initial 10% design toward a 60% design and a guaranteed maximum price (GMP). Brett Van Hazel, program management office director for the project, told the council amendment No. 5 would have authorized design development to 60% for a not-to-exceed $50 million fee to Kiewit, and that staff had paused contract work when council asked for more analysis. Staff said that if council approved the amendment it would deliver a 30% design and updated cost model, then a 60% design and a GMP for council review.

Council members pressed staff and the developer about cost, schedule and alternatives. City staff said earlier conceptual estimates and the market have driven costs upward; the engineering and procurement teams told council that as design matures cost certainty improves but that significant escalation and scope changes can occur while market pricing is volatile. City staff also reviewed a range of potential water supplies — including Nueces River groundwater captures, Evangeline aquifer options and reuse/treated effluent — and offered best-case and more-likely timelines for each.

Several council members said they were unwilling to commit to a multi‑hundred‑million‑dollar construction program without clearer cost and environmental outcomes. “This is an expensive project in a difficult location,” one member said during the discussion; others asked whether the city could instead pursue shorter‑term groundwater or reuse options that could be brought online sooner and at lower cost.

More than 150 people registered or spoke during the public comment period. Dozens of people urged council to halt the Inner Harbor plan — citing environmental risk to Corpus Christi Bay, the proximity of intake and discharge locations in a semi‑enclosed harbor, the potential for elevated salinity and low oxygen events, and the historic legacy of heavy industrial impact on the Hillcrest neighborhood. Other speakers, including representatives of industrial users, urged the council to proceed with desalination to secure a reliable long‑term water supply for both municipal and industrial users.

Mayor Paulette Guajardo and members of city staff repeatedly emphasized that no final construction contract or financing decision has been made. Staff also noted the city already holds state loan proceeds earmarked for the project and that the Texas Water Development Board requested notice by early September if the city wishes to be included in a current bond sale. Staff warned that delaying the decision could require the city to revisit financing timing and could affect project schedule.

Council members asked for additional independent review steps before approving large design and construction commitments. Staff said they will provide a set of options — including continuing with the current design‑build team toward a GMP, switching to the second‑ranked proposer under the procurement, or redirecting effort and funding toward alternative sources such as groundwater or reuse — and indicate schedule and budget implications for each. The council did not vote on the design amendment at the meeting.

The council’s discussion also included a briefing on related financing mechanics: the city has previously sold and set aside state water development funds and municipal bonds for the project; those funds come with legal and timing constraints that staff said would need to be addressed if the council changed direction. Staff also told the council the city could explore additional state assistance but that timing and eligibility are uncertain.

What happens next: staff will return with an options package that lays out (a) continuation with the current design‑build path and the anticipated schedule to a GMP, (b) the consequences and schedule of re‑procuring or negotiating with an alternate proposer, and (c) the schedule, cost and permitting timelines for identified alternatives such as Evangeline groundwater captures, Nueces River wellfield water and reuse projects. Council members said they expect to revisit the subject quickly because the city holds funds that are being tracked for this program and the board of state funders needs schedule clarity by early September.

The council’s deliberations underscore the tradeoffs cities are facing nationwide: the need to add resilient new water supplies, the technical and environmental risks of proposed solutions, and the fiscal and political challenges of financing large, long‑lived projects. Corpus Christi residents will see a follow‑up presentation with specific independent modeling and finance scenarios before any final authorization for construction contracts or new bond issuance.
