After the public hearing, the director shall determine, based upon the facts presented and other relevant data available, if there is a need for the creation of a cotton boll weevil control district and if the need is sufficient to justify the holding of a referendum thereon. Subsequent petitions relating to the same locale may not be filed or action taken thereon within one year from the date the director has recorded a determination denying the need for the creation of a cotton boll weevil control district.
