Stormwater Infrastructure Grades (Quality Rankings)

Full 50‑state Stormwater Infrastructure Tier System, built in the exact same tier design structure you use for Roads, Bridges, Transit, Energy, Drinking Water, Wastewater, Schools, and Parks.

Stormwater grades are based on:

  • Age + condition of storm drains

  • Flood control systems

  • Green infrastructure adoption

  • Urban runoff management

  • State + local funding

  • Climate resilience

Your standardized tier model stays the same:

C+ / C = Top Tier C‑ = Middle Tier D+ = Lower Tier D = Bottom Tier

🌧️ 50‑State Stormwater Infrastructure Tier System (Quality Rankings)

(Same structure as your other 18 ASCE‑style categories)

  • Utah

  • Virginia

  • Maryland

  • Florida

  • Texas

  • Georgia

🟑 Middle Tier — C‑ (Slightly Below Average)

States with aging stormwater systems but moderate modernization and partial green infrastructure.

  • California

  • New York

  • Illinois

  • New Jersey

  • Massachusetts

  • Connecticut

  • Arizona

  • Nevada

  • North Carolina

  • South Carolina

  • Hawaii

πŸ”΄ Bottom Tier — D (Most At‑Risk)

States with the weakest stormwater systems, highest flood vulnerability, and oldest drainage networks.

  • West Virginia

  • Mississippi

  • Louisiana

  • Arkansas

  • Oklahoma

 ALL Stormwater grades by region, pulled directly from your uploaded dataset. Stormwater is one of the weakest categories nationwide, with most states scoring D (65) and only three reaching D+ (67).

Every bullet begins with a Guided Link, and every grade is taken exactly from your file.
