ESI completed a Contamination Screening Evaluation (CSE) for a proposed, 4-lane, limited access highway from the SR 23 (Brannan Field Chaffee Rd.) / SR 21 (Blanding Blvd.) interchange in Clay County, to the I-95/SR 9B interchange in St. Johns County. The CSE was completed in accordance with the FDOT PD&E Manual, Chapter 22 to evaluate six (6) possible alignment alternatives that comprised approximately 23.5 to 33.5 miles (depending on the alternative selected) for an intended new, 4-lane, limited access rural freeway, and a new 4-lane crossing of the St. Johns River, all of which would be an addition to the Florida Intrastate Highway System (FIHS).  Specific areas of environmental concern in Clay County included proposed interchanges at Blanding Boulevard, at three (3) locations along the length of SR-13, and at areas surrounding Reynolds Industrial Park.
