This morning officials announced the winners of the "Reinventing Grand Army Plaza" competition, a contest that drew 200+ proposals for transforming the gateway to Prospect Park into a public space worthy of its landmark status. A jury composed mainly of designers, planners and community advocates selected four designs to receive cash prizes, while winnowing the entrants to a field of 30, to be displayed on-site through October 13. Members of the public will be able to vote for their favorites via text message, with results announced on October 8.

From a tipster comes this story of what happens when a cyclist tries to conduct business using the "vehicles only" windows at the Commerce Bank branch on Prospect Park Southwest at Park Circle.

Before the four "New York City Waterfalls" began gushing along the East River this June, DOT marked a bike route passing by each installation and released a guide to go with it. In this Streetfilm Elizabeth Press shows us a recent bike tour of the falls, led by DOT commish Janette Sadik-Khan. Special bonus feature: commentary from "Waterfalls" artist Olafur Eliasson about his work.

Here's a modest proposal for evaluating the success of a Summer Streets event: Measure the amount of time kids are able to run and play without their parents having to worry about them being hit by a car, the number of friends you bump into and new people you meet, the pounds of automobile exhaust and carbon that aren't being spewed into the hot summer air, the amount of horn-honking, engine-revving and boom stereos you're not hearing, and whether your local merchants are happy about the event and making more money than they usually do on a slow summer weekend.

Brooklyn's Bedford Avenue will be going car-free for four Saturdays this summer. If you want to be a part of making the event happen, Billburg.com invites you to a "Williamsburg Walks" volunteer orientation session tonight.
