Neighbor Drainage Conflict: Redirecting Downspouts and Grading

A Michigan homeowner's new house sits higher than a neighbor's; rainwater flows into the neighbor's yard, flooding it. A retaining wall abuts the property line. Downspouts run to the road, but the building inspector prohibited that. Neighbor's downspouts discharge at the flood zone.

Redirect all downspouts toward the pond (downhill) using solid drain tile. If gravity allows, extend pipes to the water. If not, a dry well or infiltration trench on the homeowner's property can capture runoff. Coordinate with the neighbor to redirect their downspouts too. A swale along the property line can channel water to the pond. The inspector's concern about road discharge is valid—ice hazard and municipal codes often prohibit it.
