Stormwater Fee Information

The revenue from the stormwater fee will fund:
  • Stormwater Capital Projects
  • Proactive maintenance of public stormwater infrastructure.
  • Watershed studies to identify the most impactful projects.
  • Increased inspections of stormwater management facilities.
  • Education on stormwater management issues and action that local residents and business can take to address Radnor's stormwater challenges.
