The perimeter improvements project included the construction of three (3) new signage elements/architectural landscape features. Two signage elements measure 30 feet by 5 feet and 20 feet tall. One combined sign/architectural feature measures more than 110 feet long and 20 feet tall. Construction consisted of poured concrete foundations, reinforced masonry block, brick and precast concrete.
Twenty-four soil borings were completed across the site in January 2005 as part of the geotechnical investigation for the then-proposed connector building and site improvements. The test borings identified undocumented fill soils to depths ranging from 3.5 feet to 18.5 feet. The fill was described as silty clay with varying quantities of gravel, brick, concrete and organic material. The moisture content, density, and strength of the fill were also highly variable. Soft to stiff silty clay Peoria loess was encountered beneath the fill. Stiff to very stiff lean to fat clay Loveland loess was encountered in four of the test borings at depths of 40 feet to 50 feet.
