An additional 20,600 square feet of new sales floor/warehouse space, 1,400 square feet for a new food court/food prep kitchen and 2,400 square feet for new mechanical/fire pump room was added, as well as a new open canopy over the main entrance; which is part of a completely new façade consisting of corrugated siding and architectural metal trim. Site improvements included utilities, new loading docks and ramps, concrete and masonry site walls, added paved areas, bio treatment ponds, sanitary sewer systems, natural gas distribution system, electrical distribution systems, site lighting, curbs, pavement, striping/arrows, landscaping and irrigation.
