Council approves extension | News OK

Now, I will say, in the homeowners' defense, if you look at the city minutes and the news stories, they've never outright opposed commercial construction... they've always just wanted some reassurances and concerns addressed, each time the PUD was extended. Shadid always responded that the PUD wasn't the time to address these concerns, and that they would be addressed when a specific site plan was created (which seems to be the time now).
