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

PROJECT DESCRIPTION
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 and 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 meeting the SCOs for cover material as set forth in 6 NYCRR Part
375?6.7(d) for restricted?residential use. A demarcation layer material 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.
