RIDGELAND — Homeowners against a zoning ordinance amendment passed by the Mayor and Board of Aldermen on April 5 plan to file an appeal later this week.

The board voted 4-3 to approve a zoning ordinance amendment that, among other things, defined large master planned developments.

A similar amendment was adopted in June 2015, but came under scrutiny over proper noticing to the public.

Sheldon Alston, an attorney with Brunini, Grantham, Grower & Hewes, said on Wednesday the homeowners planned to appeal the decision within the 10-day timeframe prescribed by law.

“Our plans at the moment are to appeal the decision from the board of aldermen on April 5, 2016, where they amended the C-2 district,” Alston said.

Alston said there is also a lawsuit pending in Madison County Circuit Court on the June 2015 amendment.

Nine residents filed a lawsuit against the city, which they claim was specifically adopted to accommodate a Costco on Highland Colony Parkway south of the roundabout and Natchez Trace Parkway.

The residents who filed that suit were: Gerald Emmett Beard, Charles Jules Michel, Harold Joseph Byrd, Nils Kerem Mungan, George Thatcher Shepard Jr., Matthew Denson DeShazo, William M. Aden, Thomas I. Rice III and Joel G. Payne Jr.

They are residents in Montrachet, Dinsmor, Canterbury, Windrush and Greenwood Plantation subdivisions all west of I-55 in the Old Agency Road vicinity.

Alston said the pending lawsuit and motion to appeal are two different avenues for challenging the city’s zoning ordinance amendment.

The crux of the lawsuit charges the city with not providing proper public notice prior to passage of the June 2015 ordinance.

As part of the process, attorneys filed public records requests with the city for all communication and correspondence related to the zoning amendment, Costco, Renaissance Phase III, etc.

In total, approximately 2,900 pages of emails and documents were given by the city.

The emails included correspondence from city officials, developers, aldermen, and residents — both against and in favor of a Costco.

Last week, Ridgeland Mayor Gene McGee said with the passage of the April 5 amendment, he hoped it would save both residents and the city money in a legal challenge.
