This city’s urban shoreline on Puget Sound was never built with photo-snapping tourists in mind, or technology entrepreneurs jogging in the rain. In decades past, stretching back to the big-timber-and-fish era of the 1800s, the waterfront was a place of gaff hooks, warehouses and stink.  But as brawny old Seattle faded, the hard parts of its industrial past — a shadow-casting highway viaduct, a crumbling sea wall — remained behind like bleached fossils even as the modern gloss of restaurants, hotels and apartment towers moved in.  Part of the renovation will include ecological considerations for how the seawall is constructed, which will help juvenile salmon as they transit to and from sea.  Read more about the planned waterfront facelift here.
