Areaway Preservation

For pedestrian improvements in Pioneer Square, new ADA curb ramps at several intersections required areaways rehabilitation and strengthening. Due to historic significance, Pioneer Square Preservation Board review and approval was obtained for the ramp support design and preserving brick arches, brick or stone street wall, brick or stone building wall and columns. New concrete slabs were designed to be supported on new concrete columns and footings, and the slab thickness set such that the sidewalk surface can be shaped to represent the curb ramp slope and wings.
