As part of our Fund Exchange agreement with ODOT for the Dubarko Rd. resurfacing project we were required to bring substandard ADA ramps adjacent to the project up to standard. The sandblasting residue from the yellow curb paint removal contained enough lead that special disposal of the material was required at a cost of over $1,600.
