(a) As used in this Code section, the term:

(1) "Drug related indictment" means an indictment by a grand jury for an offense involving violation of Code Section 16-13-30; provided, however, that any such indictments which result directly from cooperation between the property owner and a law enforcement agency shall not be considered a drug related indictment for purposes of this Code section.

(2) "Substantial drug related activity" means activity resulting in six or more separate incidents resulting in drug related indictments involving violations occurring within a 12 month period on the same parcel of real property.

(b) Any owner of real property who has actual knowledge that substantial drug related activity is being conducted on such property shall be guilty of maintaining a nuisance, and such real property shall be deemed a nuisance and may be enjoined or otherwise abated as provided in this chapter.

(c) The owner of real property shall be deemed to have actual knowledge of substantial drug related activity occurring on a parcel of real property if the district attorney of the county in which the property is located notifies the owner in writing of three or more separate incidents within a 12 month period which result in drug related indictments and, after the receipt of such notice and within 12 months of the first of the incidents resulting in a drug related indictment which are the subject of such notice, three or more separate incidents occur which result in drug related indictments.

(d) The provisions of this Code section are cumulative of any other remedies and shall not be construed to repeal any other existing remedies for drug related nuisances.
