Here is a link to the application that the City of Newburyport made for the proposed 40R Smart Growth District (It has all kinds of links and information on it), it can be found here.
Here is a photo of the proposed Minco building (it is now in the public domain), which is the cornerstone of the proposed 40R District, and that I think is ugly.
Here are two of the new maps of the proposed Smart Growth 40R
And here is a table for the Water and Sewer capacity for the 40R District which also includes the number of bedrooms and the number of apartment units.
