The state has signed off on the first phase of the Four Corners streetscape project in Brookfield.  First Selectman Steve Dunn reportedly called the Department of Transportation yesterday to follow up on adjustments the agency had asked for.  Brookfield residents voted to borrow $1.7 million for the project, with the balance of the $3.5 million paid for with grants.  The project calls for sidewalks , planters and other beautification in the Four Corners area.  Construction could begin as soon as next month.
