Downspout and drainage planning
Ask how water will be directed away from the home and landscape.
Move water with intention
Downspouts should move water away from the foundation while accounting for splash, erosion, walkways, driveways and landscaping. Roof valleys can concentrate flow and deserve specific discussion.
Questions to ask
Ask where discharge will terminate, whether extensions or another routing approach are needed and how the plan handles standing water or washout. The Downspout Planner can help you organize the conversation.
