It is the purpose of this chapter to encourage new manufacturing and industrial uses on undeveloped or underutilized lands zoned for industrial and manufacturing uses in targeted urban areas, thereby increasing employment opportunities for family living wage jobs. Cities that plan under the growth management act meeting the criteria of this chapter where the governing authority of the affected city has found there is insufficient family living wage jobs for its wage earning population may designate a portion of the city's industrial and manufacturing zoned and undeveloped land to receive an ad valorem tax exemption for the value of new construction of industrial/manufacturing facilities within the designated area.
