RFB-2024-018 - Contract No. 1 – 701 Lawrence Street (OU-2) Remediation of Contaminated Soil

The Work of this Contract consists primarily of the placement and compaction of a 2-foot soil
cover at 701 Lawrence Street in the City of Rome, New York. Currently, soil stockpiles exist at
the southern portion of the site along with grade depressions that retain stormwater with no
drainage. The stockpiles will be excavated along with other areas of the site and this material
will be placed and graded in low‐lying areas as fill. The site boundary will slope from the
northwest to the southeast to drainage pathways to the south-southeast of the site. The balance of
cut and fill from the site will promote drainage to this area. This will also allow for the two‐foot
soil cover system to be placed uniformly across the site that promotes stormwater drainage.
The final cover system will be constructed so that it functions with minimum maintenance,
promotes drainage, and minimizes erosion. Although the ROD allows for use of pavement as a
cover material, the design of the cover system calls for providing a minimum 18‐inch‐thick soil
layer and 6 inches of topsoil with vegetative cover meeting the SCOs for cover material as set
forth in 6 NYCRR Part 375‐6.7(d) for restricted‐residential use. A demarcation layer will be
installed prior to placement of the soil cover at the interface between the unexcavated soil and
the imported backfill. The demarcation layer will provide a physical boundary between the
subsurface fill material and the overlying certified cover soil system.
