HCIDC HAS IN THE PAST DECADE FACILITATED THE DEVELOPMENT OF TWO MAJOR MANUFACTURING OPERATIONS IN CROSSROADS INDUSTRIAL PARK, WEST LIBERTY FOODS/MILLARD REFRIGERATED SERVICES AND FLUORO-SEAL, THAT REPRESENT MORE THAN 6.9 MILLION TAXABLE VALUATION AND 500+ JOBS. HCIDC COMPLETED CONSTRUCTION OF A THIRD SPECULATIVE SHELL BUILDING IN 2009, WHICH WAS SOLD DURING 2015. THE PRESENCE OF THE SHELL BUILDING WAS A VITAL FIRST STEP IN CONVINCING GOLDEN EAGLE DISTRIBUTING CO.

FINALLY, HCIDC, WORKING THROUGH ITS AFFILIATE, THE MOUNT PLEASANT AREA DEVELOPMENT COMMISSION, MAINTAINS PROGRAMS IN BUSINESS ATTRACTION, BUSINESS RETENTION & EXPANSION, ENTREPRENEURIAL SUPPORT, EDUCATION, AND COMMUNITY DEVELOPMENT. |
