Downspout Disconnection

The City offers free downspout disconnection safety inspections, parts and labor from June to August.

Disconnect for healthier streams 

Downspout disconnections work in areas of Gresham where water can easily filter into your landscape and help recharge groundwater.

Does my property qualify? 

Your property may be suitable for downspout disconnection.

  1. Visit the GreshamView map.

  3. Select "Incentives and Grant Eligible Areas"
  4. Select Downspout Disconnection/Rain Garden Area; then select “Hide map layers.”
