Julie Dalsaso launched her kayak from Blackwell Island on Monday afternoon, using the brief paddling excursion on the Spokane River to demonstrate the value of a small piece of public waterfront. The land where she parked her vehicle and carried her kayak down an embankment is the old U.S. Highway 95 right of way, where a bridge once crossed the river. The city of Coeur d’Alene owns the 1.83-acre parcel. But the land has been identified as “surplus,” and could be sold to help pay for a $1.65 million remodeling project at City Hall.
