Creeks, hills and water mains
Silver Spring sits on rolling ground cut by small streams such as Sligo Creek, and heavy storms can send runoff quickly toward low spots. Houses near creek valleys or at the bottom of a slope may see seepage, window well overflow or basement flooding when rain is intense.
Water service here comes from a regional utility, and in cold snaps water mains in the area can break, leading to pressure changes or street flooding. Inside homes, pipes on exterior walls and in unheated spaces can freeze and split. A frozen line may not leak until it thaws, which is when the damage starts.
