Foster Center FAQ
Do I need a permit to regrade my Providence yard?
If you move more than 50 cubic yards of earth, change drainage patterns, or create slopes steeper than 2:1, yes. Minor landscaping below that threshold is typically exempt but must not adversely affect neighbors.
Can I send my gutter downspouts toward my neighbor?
No. Under Rhode Island's reasonable use rule (Butler v. Bruno), concentrating and directing runoff onto adjacent property creates liability. Discharge to your own yard, to a storm drain, or to a dry well.
