Observe during safe conditions
After normal rain, look for persistent ponding, erosion or water flowing toward the structure.
Keep notes by location
Repeated observations are more useful than one dramatic storm.
Distinguish surface from buried systems
Visible runoff does not reveal the condition of underground drains.
Use qualified help for persistent problems
Foundation drainage, sewer connections and major grading changes can involve permits and specialized work.
