The Coney Island Boardwalk has been seriously deteriorating over the years, and Borough President Marty Markowitz says it's time for Washington to help save it. He tells the Daily News what anyone who's drunkenly stumbled around the Boardwalk with a Pina Colada knows all too well: "It’s in horrible condition." The city is currently spending $5 million to renovate a small section of the Boardwalk (with plastic!), but a total overhaul of the entire 3-mile promenade is estimated to cost more than $200 million. That's close to half of the total $500 million for infrastructure projects the city expects to receive as part of the federal stimulus package, and Markowitz says it's worth it, because Coney Island "generates jobs and it generates family fun, which is so needed right now." But with Astroland gone and other Boardwalk businesses getting squeezed by developer Joe Sitt, one wonders how much fun a family can really expect in the summers to come. On the other hand, falling into one of those treacherous holes in the Boardwalk is no fun at all.
