Not sure how to respond to such pie in the sky. If he was calling for a 100-foot wide greenway, including a walkway and landscaping, I'd say that's a great idea worthy of public support, but it's probably not politically or economically feasible.
But he's not calling for 100 feet. He's calling for a greenway that's up to 1000 feet wide in some areas, including the 7-acre Mazda dealership, Goodyear, White Manna, Budget car rental, Harley's Pub, the Nissan Dealership, Home Liquors, , the car wash, and more. He's even targeting office buildings and a 6-story apartment building (circa 1989) on the east side of River Street near the Midtown Bridge Extension. It's just not going to happen. There's no point to discussing how great it would or wouldn't be.
The only other person I've ever heard talk of something like this was Lenny Nix, and even he only wanted to do that on South River Street.
Weinstock would be better off calling for the completion of the Hackensack River Walkway, and perhaps, a 50-foot greenway. That's within the realm of reality, and Yes, it would increase nearby property values to compensate for the loss of the 50 feet. But not more than that.
And here's some insight. I think the downtown merchants and their little BID district don't want to talk about the river because they think it's potentially competition for Main Street with cafe's, restaurants, and possible stores along a boardwalk-type structure. Bad thinking, wrong thinking. It can and should all link together and bring mutual prosperity
