The developer working on Valero's former Benicia refinery has already said how much of the new neighborhood's infrastructure would be paid for. Signature Development Group says it will privately fund the environmental cleanup. It has proposed a Community Facilities District to pay for new roads, water and sewer connections, and parks, and that district would collect special property taxes from the people who own property inside the redevelopment site, The Benicia Bridge reported in July.
That changes the math for anyone watching these 900 acres along East Second Street. Some will be future homebuyers, some industrial tenants and some investors. Since refining stopped in April, the land has stayed in use, under a proposed agreement with a set term. When it does turn over, part of the cost of building it out is designed to land on the people who buy in.
What the proposed tax district would pay for
Signature submitted its preliminary plans to the City of Benicia on May 15, 2026. The proposal lays out the following:
- Industry: up to 3 million square feet on the old refining core, aimed at advanced manufacturing such as robotics. Signature has told the Vallejo Sun it does not plan a data center on the site.
- Housing: up to 3,500 units, mostly single-family homes, plus townhouses and a 4- to 5-story affordable apartment building. Most of the homes would sit on the meadows beside East Second Street that now serve as the refinery's buffer zone.
- Retail: up to 600,000 square feet, including a grocery-anchored shopping center at Park and Bayshore roads.
- Open space: about 150 acres of parks, greenbelts and trails, including a 35-acre central park.
California created Community Facilities Districts after Proposition 13 so local governments could fund improvements through special, limited property taxes. The state had at least 1,200 of them as of 2024, and Benicia has looked at the tool before, according to The Benicia Bridge. Here, the district would cover the public infrastructure a mostly empty buffer meadow lacks. For now, the district exists only as a proposal in Signature's pre-application.

Why the ground is still occupied
Valero stopped refining in April 2026 but kept importing, storing and distributing refined petroleum products, including gasoline, at the site. The city's position is that fuel import operations are not allowed under its current regulations and permits and would need zoning clearance. Valero disagrees, The Benicia Bridge reported.
After months of talks among the city, the state and Valero, both sides agreed to set that dispute aside. The result is a Standstill Agreement that went to the City Council on October 20. Under the city staff report, the agreement as drafted works like this:
| Term | As drafted |
|---|---|
| Length | Two years from the effective date, unless terminated earlier |
| City's side | No enforcement action during the term claiming fuel imports violate city rules or permits |
| After the term | The city keeps its right to object, but cannot go after imports conducted during the term |
| Inventory cap | 2.1 million barrels of refined product on site at any time, with about 500,000 expected on average |
| Operator change | Valero gives 30 days' written notice; the city may terminate if Valero is no longer the operator |
| Safety | Emergency response capacity under an October 1, 2026 MOU with the Fire Chief, plus routine vegetation management |
| State payment | $5.25 million covering October 1, 2026 through June 30, 2027, due by January 15, 2027 |
| Second payment | The city will seek at least $7 million for fiscal year 2027-28, due by January 15, 2028 |
| Development filing | Valero and Signature to submit a formal mixed-use application by December 31, 2026 |
The staff report calls for a two-year term. The City Manager's message ahead of the meeting described imports continuing through June 30, 2027, which matches the first payment period. Either way, the draft ties the two tracks together. The same document that lets fuel keep moving across the property also asks for a formal development application within about two months.
Why the city has a reason to agree
The state's payments are labeled unrestricted community benefit funding, and the city's budget gap explains why that label matters. The City of Benicia expects to lose $7.5 million to $8 million a year in property tax, water sales and electrical energy user tax revenue because of the closure, The Benicia Bridge reported in September. KQED reported a higher figure of $10.8 million a year in April.
The city's largest grant in years cannot be used to close that gap. In September the Bay Area Air District awarded Benicia $30 million over five years, and the Benicia Unified School District another $10 million. The money comes from Valero's record $82 million fine in 2024. It is restricted to approved projects such as 600 new trees, energy upgrades to city buildings, electric police vehicles and a fire engine, car chargers, and bike and pedestrian routes. It cannot pay for general city services.
That leaves the standstill payments as one of the few new sources of flexible money, and the city collects them only while the fuel terminal keeps running. Interim fuel operations and city finances are linked, at least until fiscal year 2027-28.
What the industrial ground is being zoned to become
About $11 million of the Air District grant is set aside for coordinating safe decommissioning of the refinery and laying the groundwork for new industry. That includes a new General Plan, a new Industrial Zoning Code, and a Clean Industry Revitalization Initiative aimed at battery manufacturing, green energy, port-related logistics and shipbuilding. City Manager Mario Giuliani described what the city has now as "a zoning code from the 1970s, a General Plan from the 1990s, anchored by an industry of the 1960s," as quoted by The Benicia Bridge.
One part of the industrial rulebook is moving now. On October 20 the council voted 4-1 to introduce a data-center ordinance and scheduled a second reading for October 27, the Vallejo Sun reported. The city's staff report describes these limits:
- A 20-megawatt maximum per facility
- No combustion backup generators
- Required measures to reduce power and potable water use
- Annual compliance and consumption reporting
- Conditional use permits with public review, and the council added Planning Commission review of every proposal
For an investor sizing up the Benicia Industrial Park, this is the first sign of how the city plans to screen new uses. Large data centers are effectively off the table. The uses the grant names, which are manufacturing, logistics, energy and shipbuilding, line up with Signature's robotics-oriented industrial program on the refinery core.
The sequence before anything gets built
Signature has described the steps as environmental review, rezoning, demolition and cleanup, City Council approval, and then construction. The Vallejo Sun characterized that as a process of several years. Signature's documents say there will be a full environmental impact assessment. Valero hired Signature and still owns the land, and the City of Benicia's current development page lists the roughly 900-acre redevelopment as an active application.
These are the dates already on the calendar:
- October 1, 2026: the first state payment period and the emergency response MOU begin
- October 27, 2026: second reading of the data-center ordinance
- December 31, 2026: deadline in the draft agreement for the formal mixed-use application
- January 15, 2027: deadline for the initial $5.25 million state payment
- June 30, 2027: end of the first payment period
- January 15, 2028: deadline for the second payment
Frequently asked questions
Is the Benicia refinery still operating? Refining stopped in April 2026. Valero still imports, stores and distributes refined fuels on the property, and the draft Standstill Agreement would allow that to continue during its term.
Who decides what gets built on the 900 acres? Valero owns the land and hired Signature Development Group. Any project still has to go through environmental review, rezoning and City Council approval.
Would the new homes carry an extra property tax? Signature has proposed a Community Facilities District, a special tax on owners inside the redevelopment site, to fund roads, utilities and parks. The district appears in the developer's pre-application as a proposal.
Will a data center be built there? Signature has said it has no data center plans for the site. Separately, the city's proposed ordinance caps data centers at 20 megawatts and requires permits and public review.
