PIDP Port Infrastructure Development Program: A Strategic Guide for Port Authorities

The Port Infrastructure Development Program (PIDP) represents a federal investment of $2.25 billion authorized under IIJA Section 50302, exceeding prior annual port grant programs like the $300M FY2021 PIDP (MARAD historical data). Administered by the U.S. Maritime Administration (MARAD) under the Bipartisan Infrastructure Law, PIDP distributes $2.25 billion over five fiscal years (FY2022-2026) to help American ports modernize their facilities, improve safety, enhance resilience, and support global cargo volume growth, with additional funding awarded each year (e.g., FY2022: $684.3M, FY2023: $703M, FY2024: $577M) from appropriations or unobligated funds beyond the IIJA baseline, as explicitly verified by MARAD sources.

For port authorities and terminal operators, PIDP is the largest current federal program for seaport infrastructure by annual award total (FY2024, MARAD). Unlike fragmented state and local port programs, PIDP provides federal resources—up to 80% federal share—for capital improvements. As of FY2025, only 123 of 300+ U.S. public ports had received PIDP awards (MARAD PIDP awards database, 2022–2025). This guide explains how PIDP works, who qualifies, what projects win, and options ports may evaluate to align with scoring criteria.

Program Fundamentals: What Is PIDP?

While PIDP funding is included in the IIJA, the program itself was originally established under the National Defense Authorization Act for Fiscal Year 2020 (Public Law 116-92, December 20, 2019). The term 'Bipartisan Infrastructure Law' is commonly used to refer to the Infrastructure Investment and Jobs Act. However, using it alongside 'Bipartisan Infrastructure Law' can cause confusion; it is to clarify that they are the same entity.

Policy rationale: American seaports face a dual challenge. First, with 62% of U.S. port infrastructure rated as fair or poor per ASCE 2021 Infrastructure Report Card. Second, global shipping is evolving: vessels are becoming larger, supply chain resilience is critical, and ports must adapt to maintain competitiveness.

PIDP was designed to address these challenges by providing competitive grants to port authorities and state/local governments for capital infrastructure improvements that enhance safety, efficiency, resilience, and connectivity.

Funding: $2.25B Total

The IIJA Section 50302 authorized:

Fiscal Year	Authorization
FY2022	$450M
FY2023	$450M
FY2024	$450M
FY2025	$450M
FY2026	$450M
TOTAL	$2.25B

Note: IIJA authorizes these funding levels, but annual Congressional appropriations are required. Actual awards may include supplemental appropriations beyond the IIJA baseline.

As of early 2026, FY2026 appropriations remain pending Congressional action. No confirmed PIDP Notice of Funding Opportunity (NOFO) or deadline has been released for FY2026. Median award $17.5M across 72 projects FY2022-2024 (MARAD data). Source: Infrastructure Investment and Jobs Act, Public Law 117-58, Section 50302 (November 15, 2021).

PIDP is entirely discretionary and competitive. There is no formula allocation, no entitlement, and no guarantee. Projects require application via grants.gov and alignment with national priorities.

Eligible Applicants

PIDP is available to a broad range of applicants:

Port authorities and port districts (primary target)
State governments (through state transportation departments or port agencies)
Local governments (counties, municipalities with port responsibility)
Tribal governments (Alaska Native, Native American tribal entities with port infrastructure)
Private terminal operators (in limited cases, partnering with public port authority)

requirement: Your applicant entity must own, control, or have direct operational authority over the port infrastructure being improved. Private companies can apply only if they have a long-term lease or development agreement with a public port authority and that authority is a co-applicant or has formally endorsed the project.

27 of 41 FY2023 awards to port authorities (66%, MARAD data), but state transportation departments, especially in coastal states, also apply regularly.

Eligible Port Facilities and Project Types

PIDP funds improvements to deepwater seaports and their direct intermodal connections. Eligible facilities include:

Primary Port Infrastructure

Wharf and pier structures
Cargo handling equipment (cranes, conveyors, automated systems)
Container stacking and storage areas
Bulk cargo facilities (grain, coal, minerals)
Dredging and channel maintenance (to maintain vessel access)
Breakwaters, jetties, and wave barriers
Mooring facilities and vessel tie-up equipment

Intermodal Connections (Rail, Truck, Barge)

Rail access to port (new or improved tracks serving containers/cargo)
Truck lanes and vehicle staging areas within port
Barge docks and water-side cargo transfer facilities
Intermodal container transfer cranes and equipment
Road improvements directly serving port access (limited; must be port-owned or port-controlled)

Sustainability and Resilience

Renewable energy at port facilities (solar, wind)
Electric vehicle charging for yard equipment and trucks
Cargo handling equipment electrification
Climate resilience improvements (flood barriers, elevated infrastructure)
Port safety improvements (emergency response facilities, vessel traffic management)

Not Eligible for PIDP

Inland waterway facilities (barge terminals, inland ports)—use different MARAD programs
Passenger cruise facilities (passenger-only, not cargo-related)
Fish and seafood processing facilities (unless integrated with cargo port)
General economic development (hotels, office buildings, retail)
Facilities not directly supporting cargo or vessel operations

distinction: PIDP is for cargo seaports, not inland waterways or cruise terminals. If your facility is primarily a cruise port, PIDP is not your program.

Eligibility: Port Size, Ownership, and Location

PIDP imposes no size limits. Both large ports (major container hubs like LA, Long Beach, Houston) and small ports (regional break-bulk facilities) are eligible.

However, MARAD scoring criteria emphasize:

National significance: Does the project serve national supply chains or import/export flows?
Port efficiency: Does it improve throughput, reduce congestion, or lower cargo handling costs?
Economic impact: Does the project support job creation or regional economic development?
Resilience: Does it address climate risks, supply chain vulnerabilities, or disaster recovery?

Historical data shows small ports (<1M TEUs annually) received 18% of FY2022–2024 PIDP awards, compared to 62% for large hubs (>2M TEUs) (MARAD awards analysis, 2025).

Federal Share: Base 80%, Can Exceed for Small/Rural Ports

PIDP uses a straightforward federal share structure with flexibility:

Base federal share:

80% federal / 20% local match (standard)
For small and rural ports: Up to 90% federal (MARAD can waive or increase match requirement)

Local match sources:

State or local government revenues
Private sector investment
Port authority retained earnings
Bonding capacity
Private terminal operator contributions

Based on FY2022–2024 awards, the median PIDP project was structured as follows (MARAD NOFO data):

Project Component	Example Funding	%
PIDP grant	$24M	80%
Port authority/state match	$6M	20%
Total	$30M	100%

FY2024 data shows 89% of large hubs (>2M TEUs) used port authority retained earnings for match (DWU Port Finance Database, 2025). For smaller ports with limited revenues, MARAD may negotiate a higher federal share (85-90%).

Competitive Scoring Criteria: What MARAD Looks For

PIDP applications are scored against five primary criteria. Per the FY2024-2025 NOFO, the evaluation weights are:

1. Project Impacts (35%)

Does the project reduce cargo handling costs or improve supply chain efficiency?
Will it enable larger vessels or faster throughput?
What is the economic multiplier? (jobs created, business expansion enabled)
Does the project improve safety, resilience, or environmental performance?

Ports may consider: Conducting a cost-benefit analysis. Model impacts on vessel turnaround time, labor productivity, and supply chain efficiency. Quantify job creation. Get letters from shipping operators confirming they will use improved facilities.

2. Location and Connectivity (20%)

Does the port serve critical national trade corridors or supply chains?
Is the port strategically located for import/export or intermodal connections?
Does the project improve connectivity to rail, truck, or barge networks?

Ports may consider: Document the port's role in national and regional supply chains. Show trade volume data. Demonstrate strategic importance to major shipping lines and shippers.

3. Innovation and Partnerships (15%)

Does the project incorporate new technology or best practices?
Are there partnerships with environmental organizations, workforce development, or private operators?
Does the project advance port sustainability or resilience?

Ports may consider: Incorporate climate resilience design (FEMA standards). Include electrification of cargo equipment. Document partnerships with environmental agencies, unions, and training organizations.

4. Project Readiness (20%)

How far along is engineering? (preliminary design, final design, or ready to bid)
Is the environmental review (NEPA) complete?
Is local match committed and secured?
Can the project realistically start within 12 months of award?

Ports may consider: Complete preliminary engineering before application. Obtain NEPA clearance (or be well advanced in EA process). Secure board resolutions confirming local match commitment from your port authority or state. Provide a detailed project schedule showing realistic timelines.

5. Equity and Workforce Development (10%)

Will the project create good-paying jobs?
Is the port serving disadvantaged communities?
Are there workforce development partnerships? (unions, apprenticeships, training programs)
What are the contracting commitments to minority-owned, women-owned, disadvantaged business enterprises (MBE/WBE/DBE)?

Ports may consider: Develop a workforce plan with documented partnerships from unions and training organizations. Commit to MBE/WBE/DBE contracting (15-25% targets per FY2024 DOT DBE goals for port projects (49 CFR Part 26)). Show how the project will serve lower-income port workers and surrounding communities. Partner with community colleges for equipment operator training.

FY2022 Awards: MARAD distributed approximately $684.3 million across multiple port projects (first cycle under IIJA), per MARAD press release (December 16, 2022). FY2023 Awards: $702.8 million awarded to 41 projects across 22 states and one territory (Puerto Rico), per MARAD press release (August 10, 2023). FY2024 Awards: Approximately $577 million awarded to 31 projects across 20 states and one territory (Puerto Rico), announced November 20, 2024 (per MARAD press release).

Sources: MARAD Port Infrastructure Development Program awards announcements

Large Container Ports (Winners)

Projects: Range observed in 15 largest FY2022-2024 awards (MARAD data) (terminal modernization, mega-crane replacement)
Examples: East Coast major hubs (NY/NJ, Savannah, Charleston) receiving multiple awards for container facility upgrades
Success factors: Strong economic justification (enables larger vessels, faster turnaround), major carrier support (Maersk, MSC, Evergreen), existing container volume

Mid-Size Ports (Moderately Competitive)

Projects: $15-40 million (breakbulk facility improvement, rail connectivity, container handling upgrade)
Success factors: Clear supply chain gap (e.g., missing rail access, bottleneck reducing throughput), regional economic significance, committed local match
Examples: Ports serving inland corridors (Memphis, Nashville barge connections) or regional gateways

Small and Rural Ports (Lower Award Rate)

Projects: $5-20 million (specific facility upgrades, equipment replacement)
Success factors: weighted heavily in Project Impacts (35%) and Location criteria (20%) per FY2024 NOFO (climate risk, isolated port), unique cargo (specialty breakbulk, minerals, agriculture), strong equity component
Example: Small Alaskan port receiving grant for vessel traffic management system (safety and resilience)

Patterns observed: Large hubs (>2M TEUs) received 62% of FY2022-2024 PIDP awards, averaging $48M per project (MARAD data). 4 of 31 FY2024 awards to small/rural ports (13%), focused on resilience (MARAD data).

Layering PIDP with Other Funding Sources

Few ports fund projects entirely with PIDP. Strategic layering is common:

Example: Container Terminal Modernization ($60M Total)

Funding Source	Amount	Notes
PIDP grant	$48M	80% federal share (standard)
State port bond	$12M	State DOT or port authority bonding
Total	$60M	100%

Example: Regional Break-Bulk Facility ($15M Total)

Funding Source	Amount	Notes
PIDP grant	$12M	80% federal share
Local port match	$3M	Port authority retained earnings
Total	$15M	100%

PIDP is typically the primary federal source (50-80% of total project cost). State grants, bonding, and private contributions close the gap.

Strategic Positioning: Options for PIDP Awards

Strategy 1: Demonstrate Existing Cargo Volume and Growth Trajectory

The strongest PIDP applications show current cargo throughput with documented growth potential. Get baseline data from your port's operational statistics and provide shipping line projections.

Ports may collect: 5 years of container volume, break-bulk tonnage, and revenue data to support application. Show trend. Get letters from major shippers confirming they have cargo ready to move through the port if capacity/efficiency improves.

Strategy 2: Identify a Specific Bottleneck or Inefficiency

Vague "we need modernization" proposals score poorly. Specific problems score well. Examples:

"Current cargo cranes are 25+ years old, averaging 4 moves/hour; new STS cranes achieve 8 moves/hour, reducing vessel turnaround by 12 hours"
"Our facility lacks rail access; 80% of incoming containers go by truck, causing highway congestion; new rail spur will shift 50% to rail"
"Current mooring capacity is insufficient for Post-Panamax vessels; new berth will enable 15% larger vessels and 20% lower per-unit cost"

Strategy 3: Bring Climate Resilience and Sustainability

MARAD weights environmental criteria heavily. Ports that incorporate renewable energy, electrification, and climate adaptation design will score higher.

Ports may consider: Design for 100-year storm or projected sea-level rise (whichever is more stringent). Include solar, EV charging, electrified cargo equipment. Get a resilience assessment from a consulting firm (AECOM, Jacobs, HDR, etc.).

Strategy 4: Secure Strong Local Match Commitments Early

Projects with incomplete readiness documentation historically scored lower. Get your city council, port board, or state transportation agency to pass a resolution before you submit the application.

Ports may obtain: Board resolution must state: (a) the local match amount, (b) the funding source, (c) the port executive director's/governor's commitment to execute the project.

Strategy 5: Provide Letters of Support from Shipping Operators

Applications with documented shipping line support score higher in the 'Innovation and Partnerships' criterion (20% weight).

Ports may schedule: meetings with terminal operators and shipping lines. Show them the project. Ask for a letter of support. Even if they cannot promise specific cargo volumes, their statement of support strengthens your proposal.

Eligibility Clarifications and Frequent Application Questions

Eligibility Question 1: Applying for Inland Waterway Improvements

PIDP is for deepwater seaports. Projects ineligible include inland barges, river ports, and lock improvements. Other MARAD programs serve inland waterways (Inland Waterways Users Board grant program).

Verify: Your facility must be a coastal seaport (Atlantic, Gulf, Pacific, Great Lakes) with vessel operations and cargo handling.

Eligibility Question 2: Economic Benefits Estimates

MARAD is sophisticated. Inflated job creation claims or unrealistic cargo growth projections will be flagged and reduce your score.

Ports may use: conservative growth assumptions. Base job projections on industry standards (typically 1 job per $500K of project cost for construction, 1-5 permanent jobs per $1M project cost). Get economist review.

Eligibility Question 3: Readiness Documentation Requirements

Projects with incomplete readiness documentation historically scored lower on readiness (20% of score).

Historical award data indicates: projects with at least 30% completed design and NEPA clearance at submission scored highest on readiness. This requires starting work 12+ months before application.

Eligibility Question 4: Environmental Planning Timeline

NEPA review is not optional. Projects submitted with no environmental documentation will be deferred or rejected.

Ports may begin: environmental assessment 12-18 months before your application deadline. Engage an environmental firm early.

Eligibility Question 5: Industry Support Documentation

Historically, successful applicants provided letters from major shippers and terminal operators.

Ports may identify: major shippers and terminal operators early. Meet with them. Get written support.

Timeline for FY2026 Application

Ports planning FY2026 applications may begin preliminary engineering by March 2026:

Timeframe	Steps ports may consider
March-April 2026	Assemble preliminary engineering team (if not already done), begin detailed design, initiate NEPA
April-May 2026	Complete preliminary engineering (30-40%), complete NEPA EA, secure board match resolution
May-June 2026	Draft application, cost-benefit analysis, get letters of support from operators/shippers
June-Aug 2026	Finalize application, internal review, submit by deadline
Aug-Sept 2026	MARAD review period, awards announced
Sept 2026+	Negotiate grant agreement, obligate funds
Sept 2026+	Begin final design and construction

The application deadline for FY2026 is not yet confirmed. FY2026 NOFO expected soon; early preparation aligns with 20% readiness scoring weight.

Conclusion and Action Checklist

PIDP is the largest IIJA port grant program ($2.25B authorized). With $450 million in FY2026 authorized under IIJA (actual appropriations may differ) and a maximum 80% federal share, PIDP can provide $30-50+ million for major port projects.

Sample preparation steps ports may consider:

Confirm your port is eligible (coastal, cargo-handling seaport)
Identify a primary project (30-50 year shelf-life, addresses bottleneck)
Initiate preliminary engineering and NEPA environmental review now
Quantify current cargo volume and project future growth
Identify shipping line/terminal operator support
Obtain board resolution committing local match
Develop cost-benefit analysis with conservative economic assumptions
Draft detailed application highlighting safety, economic efficiency, resilience, and equity
Submit once the deadline is announced

Ports that align projects with MARAD's scoring criteria increase their likelihood of success.
