Section 428: The Model for Block Grants and RAPID

Every proposal to pay disaster recovery up front, from H.R. 4669’s estimate-based grants to the Review Council’s RAPID, is a scaled-up version of a program FEMA has run since 2013: Section 428 fixed-cost funding. Its record shows what makes a fixed amount work for damaged buildings, and what makes it fail.

Status: Section 428 alternative procedures are current law (Stafford Act § 428; PAPPG v5.0 Appendix G). H.R. 4669’s upfront grants and block grants are a pending bill, and RAPID is a FEMA Review Council recommendation; both would need Congress. Status checked November 2026.

The first number may become the most important number, even though the first number is often the least reliable number in disaster recovery.GovStar, Section 428 Was the Pilot. FEMA Reform Is the Scale-Up.

1How Section 428 works today

PAPPG v5.0 pp. 289–296

Section 428 lets FEMA fund large permanent work projects on a fixed, capped estimate instead of actual costs. The applicant gives up overrun protection in exchange for flexibility and the right to keep savings.

Step 1

Agree on the damage first

FEMA, the recipient and the applicant agree on the damage description and dimensions, scope of work and hazard mitigation before the estimate is built.
The estimate covers restoring pre-disaster design and function under eligible codes, plus mitigation tied to the work actually done.
It can include design, environmental review, permitting and construction management.

Step 2

Validate and offer

FEMA develops or validates the estimate with engineers and cost estimators; its format includes contingencies for hidden damage and unforeseen requirements.
An independent expert cost panel may review it; you can request one when the federal share is at least $5 million.
FEMA sends a fixed cost offer in Grants Portal.

Step 3

Accept: the point of no return

The applicant and recipient have 30 days combined to accept; agreement must come within 18 months of the declaration.
Once accepted, the project cannot revert to standard procedures and overruns are not funded.
Appeals are generally unavailable, except for later cost adjustments such as insurance.

Flexibility

Funds move across projects

Fixed-cost funds can be shared across all your 428 projects for repair, replacement, new facilities (including land), equipment and mitigation.
Only total costs are tracked, not line items.
Most scope changes need no approval, except work on buildings 45 years or older, ground disturbance, or work in or near water.

Savings

Excess funds build resilience

Once the approved scope is done, savings can pay for mitigation on undamaged facilities, future insurance premiums, training, disaster planning and PA staff.
Never for debt, operating costs, budget gaps or the local cost share.
Propose the uses within 90 days of finishing your last 428 project.

Closeout

Certification, not reconciliation

The recipient certifies that costs relate to the approved scope within 180 days.
Insurance proceeds are credited, and obtain-and-maintain still applies.
The DHS OIG can audit any 428 project.

2What block grants and RAPID borrow from Section 428

The same design, at larger scale

Strip away the labels and the reform proposals reuse Section 428’s core features. The real difference is when the number is set and what it is tied to.

Section 428 feature	Where it reappears
A fixed amount paid before work is complete	H.R. 4669 upfront grants; the small-disaster block grant; RAPID’s 30-day transfer
No federal money for overruns	RAPID’s recommendation text (no additional funding for overruns after the one-year reconciliation)
Savings kept for resilience	RAPID: under-runs may go to mitigation or insurance
Funds flexible across projects	Block grants and RAPID: the state allocates across all projects and jurisdictions
Certification instead of line-item tracking	RAPID: two state CPA audits replace federal project review
Independent expert review of large estimates	H.R. 4669: licensed-professional estimates; no equivalent panel in RAPID
Amount tied to an agreed scope for a damaged facility	Not carried forward in RAPID, which sets the amount by formula before any facility is scoped

The one feature that matters most is the one RAPID drops. Section 428 fixes the amount only after FEMA, the state and the applicant agree on each damaged facility’s damage, scope and mitigation. RAPID fixes it from hazard data before any building has been inspected. That moves Section 428’s project-level estimate risk up to the whole disaster, where it becomes basis risk.

4The track record: NYC and Puerto Rico

GovStar analysis

The upside · NYC after Sandy

Fixed amounts work for capable owners

Large asset-owning agencies with facility inventories, engineering data and insurance schedules.
Capital-budget capacity to manage the timing between FEMA funds, project delivery and local financing.
Professional support to challenge weak scope or price assumptions before accepting a fixed amount.
A large portfolio, so overruns on one project could be offset by savings on another.

The stress test · Puerto Rico after Maria

Fixed amounts break under time and scale

Section 428 became the main recovery architecture for thousands of permanent-work projects.
Island logistics, imported materials, labor scarcity and limited contractor capacity made pricing hard.
Estimates set early went stale as procurement and construction stretched over years.
System-scale reconstruction of power, water and public buildings needed sampling and portfolio estimates.

Four failure modes any fixed-amount model must solve

Failure mode	How it happens	Why it matters at block-grant or RAPID scale
Scope immaturity	Amount fixed before design, hidden damage, codes, environmental review or mitigation are known	A formula set in 30 days knows even less than a 428 estimate set in 18 months
Local market gap	National cost data misses island, rural, remote or demand-surge markets	One statewide number cannot reflect very different local markets
Inflation and delay	Construction happens years after the amount was set	A fixed grant is fixed in nominal dollars; an eight-year RAPID window compounds the effect
Capacity bottleneck	Applicants lack engineers, estimators and grant staff	Small governments cannot defend their share of a state allocation

5A sustainable policy for funding damaged buildings

GovStar recommendations

Section 428 shows that fixed amounts can speed recovery and reward good stewardship. Its failures show what has to come with them. GovStar’s framework keeps the speed of block grants and RAPID while restoring the facility-level tie that made 428 defensible.

Treat any formula or block payment as an advance, not the final amount.Use it for cash flow, then true up permanent work at the facility level, the way 428 ties the amount to an agreed scope.
Value buildings by system before the disaster.A Smart Asset Registry with UNIFORMAT II replacement values lets a 30-day estimate reflect each building’s actual damaged systems.
Label every estimate by maturity.Conceptual, registry-based, engineer-validated, bid-based and final reconciled numbers carry different risk and should be used differently.
Require local market factors and escalation.Account for rural, island, tribal, high-cost urban and demand-surge markets, and show escalation assumptions to the construction midpoint.
Keep independent review for large estimates.Extend 428’s $5 million expert-panel safeguard to block grants and state allocations.
Allow adjustment triggers.Inflation beyond a set band, latent damage, code and environmental requirements, insurance resolution, long-lead equipment and failed procurement.
Keep 428’s excess-funds rule.Let savings go to mitigation, insurance and planning, which rewards accurate estimates and builds resilience.

Will a fixed amount still cover the building when construction happens?

Enter a fixed estimate (a 428 offer, an upfront grant or your share of a block grant), the time until construction, expected escalation and hidden damage. The test projects the real cost and shows the shortfall or savings. Under Section 428, a shortfall is yours and savings become excess funds. Illustrative only; use your estimator’s figures.

7What to do now

Useful under any outcome

Before an offer

Negotiate the scope, not the number

Settle the damage description, codes and mitigation before the estimate is built.
Request the expert panel at $5 million or more federal share.

Before you accept

Treat acceptance like a settlement

Have your engineer and estimator sign off on escalation and contingency.
Test the offer with the stress test above.

Before the next disaster

Build the records reform will need

Value facilities by system in a registry.
Collect local bid tabs and cost libraries; pre-position estimating support.
