Major renovation proposal at Suffolk Downs submitted to city for review

Updated:

BOSTON - Suffolk Downs may soon be home to a lot more than just a potential second Amazon headquarters.

The HYM Investment Group submitted a letter of intent for a new neighborhood at the old horse track.

The proposed development would include housing, office space, and stores - and would be 11 million square feet.

The site was purchased earlier this year by former Boston Revelopment Authority Director Tom O'Brien. Race track owners sold the property to O'Brien after losing a bid to put a casino there.

The letter of intent submitted to the Boston Planning Agency will launch a review of the project.

And while Amazon isn't expected to make its decision on the new headquarters until 2018, O'Brien said the Suffolk Downs project will move forward regardless of that decision.
