HF 4599 Summary

• Expands pavement life-cycle cost analysis requirements to all projects with 15,000 or more square yards of paving, replacing previous funding category restrictions.

• Requires analyses to be completed prior to substantial plan development and include minimum feasible alternatives: thin asphalt overlay (less than 4 inches), thin concrete overlay (4-6 inches), thick asphalt (4 inches or greater), and thick concrete (greater than 6 inches).

• Adds annual excess fuel consumption costs to life-cycle analyses based on passenger and heavy commercial vehicle traffic data, fuel prices, and fuel savings factors from the U.S. Energy Information Administration.

• Requires 21-day public review period for draft analyses and pavement selections, with documented commissioner responses to all comments and questions; if pavement type changes between concrete and asphalt, revised analysis must be posted for public review.

• Mandates certification by a licensed professional engineer before final approval, and requires public posting of all analyses and justification documents for projects beginning construction on or after January 1, 2022; effective July 1, 2022 (public review provisions effective July 1, 2023).
