Commissioners voted 3-2 for the rezoning April 3, but they learned Monday that the city did not follow proper procedures through the process, because adequate public notice was not given for the second reading.
Commissioner David Tomita said Monday the likely will begin the process anew with a first reading at Thursday's meeting and conduct second and third readings in June.
Tomita said the Board of Zoning Appeals and Planning Commission votes on the issue would not have to be reconsidered.
Approval would pave the way for the North Carolina-based engineering firm Evolve Development to begin drafting plans and collecting permits to build a 216-unit apartment complex. If those plans attain fruition, the mill would be torn down to make way for the apartments.
Some in the city, including members of the Southside Neighborhood Organization, have opposed the development.
