New modes of transportation defined eras of change in the watershed. Electrified rails brought summer resorts and country estates; automobiles ferried suburbanites to Tudor side streets; and eventually, Interstate highways funneled exurbanites into shopping centers. Two centuries later, the Euclid Creek watershed holds 68,000 residents in 11 municipalities: Beachwood, Euclid, Highland Heights, Lyndhurst, Mayfield Heights, Mayfield Village, Nottingham, Richmond Heights, Pepper Pike, South Euclid, and Willoughby Hills. Euclid Creek is a unique history of the Great Lake tributary stream and her many different communities. Drawing from numerous archives, the authors surmount municipal boundaries to show the whole history of a nearly forgotten natural landmark.
