Bill Morton's got this story, and he's got it good:
The portion of our neighborhood from the lake to the alley just West of Sheridan Road and Chase to Birchwood is currently zoned for residential uses as an RT-4 zone. The maximum density allowed in an RT-4 zone is one dwelling unit for every 1,000 square feet of lot area. A developer now wants to put up a large apartment/commercial building in the middle of the 7300 block of North Sheridan Road.
In order to be allowed to do that, he needs to convince Alderman Moore to change the zoning law and re-zone the area as a business zone, which would permit four times the density permitted under the current law and would allow business uses. WHOLE THING at Rogers Park in 1,000 Words...
