Permeable Surface Fee

Permeable Surface Fee

We are evaluating a fee/incentive program to encourage permeable surfaces and reduce stormwater runoff.

Key questions:

  • What is a fair fee structure that incentivizes permeable paving while not unduly burdening small property owners?
  • Can credits be provided for community-level projects (e.g., shared rain gardens) to encourage collaboration?
  • How to measure and verify permeability over time?

Draft mechanisms:

  • Tiered fee based on impervious area percentage.
  • Grants/credits for retrofits in low-income neighborhoods.
  • Annual verification via inspection or certified contractor reports.
