The population per acre of the proposed Isakson Living development will be nearly 3 times that of the surrounding subdivisions. Does this really belong in an area of East Cobb zoned Low and Medium Density?
Development | Zoning | Max Homes Per Acre | Average Population Per Acre |
Hidden Hollow | R-20 | 2 | 5.4 * |
Robinson Walk | R-15 | 3 | 8.1 |
Wyntergreen | RA-4 | 4 | 10.8 |
Glenside | RA-4 | 4 | 10.8 |
Isakson Living | CCRC (proposed) | ? | 26.7 ** |
* The average number of people per home in suburban US is 2.7 (http://www.nahb.org/generic.aspx?genericContentID=171558&channelID=311).
** The property is 53.7 acres, 7 acres of which is floodplain, and cannot go into density calculations. That leaves about 47 acres. The rules of Isakson Living state that only people over 62 and their spouse can live there. So, some units will be occupied by couples, and some by single people. Assuming only half the units are initially occupied by couples (probably a very low estimate), that gives 1.5 persons per unit. There are 837 units.
(837 * 1.5)/47 = 26.7.
