50 / 50 STATES POPULATED — Every state title is explicitly included in the table.
SOURCE / MODEL NOTICE: ASCE's 2025 national investment table combines Wastewater + Stormwater at $983B in needs and $293B funded for 2024–33. ASCE does not split those national figures between the two categories. This table therefore uses a transparent 40% Stormwater / 60% Wastewater modeling split. The 50-state grades and Stormwater-specific allocation multipliers are model inputs, not ASCE-published 50-state data.
$5.41T National Infrastructure • Modeled Stormwater funded: $117.20B • Modeled Stormwater needs: $393.20B • Modeled B− additional requirement: $276.00B
Variable Category-Specific Allocation Percentage: Each state's Stormwater percentage is calculated independently from its Stormwater grade weight × Stormwater-specific multiplier and normalized so all 50 states equal 100%. No Transit, Rail, Ports, Aviation, Inland Waterways, Drinking Water, Wastewater, Dams, or Public Parks allocation pattern is copied.
