BACKGROUND: Parking Garage B was constructed in 1966 on the northwest corner of North Street and Water Street. The parking garage comprises 4 floors and 681 parking spaces. In 2010 the parking garage was leased to ADM. The lease ageement requires the City to maintain the structural integrity of the building.

In December 2014, an inspection of Parking Garage C by City staff noted severe deterioration in several structural steel members. Structural engineers with Chastain and Associates, LLC reviewed the deterioration and recommended repairs at two locations. Photogaphs of the damage and repair are included in Appendix A, see photographs 1 - 3. Chastain also recommended that a thorough structural review be conducted in the parking garages.
