Through a Google search, I found reference to "CEMBA, formerly the East Warren Business Association". Further searching shows that CEM stands for Cornerstone, East English Village and Morningside.

Here's a link to their blog site: http://cembusiness.wordpress.com/

Looks a few months of out of date, but the CEM brochure lists a phone number and the businesses involved.

Maybe some of the member businesses can give you an update as to what is going on along East Warren.
