Figures_11_and_12_from_CSIR-ROR-RAP.pdf

These are engineering documents (Figure 11 and Figure 12) prepared by Fehr Graham Engineering & Environmental for the City of Urbana's demolition and site remediation project located at 211 N. Race Street in Urbana, Illinois. The documents are excavation and engineered barrier plans that detail soil boring locations, site boundaries, and environmental sampling points for a property requiring environmental cleanup. The plans show a site layout with color-coded areas indicating different excavation depths (3 feet and 3.5 feet), concrete slab removal zones, and specific soil sampling locations marked with various symbols.

The technical documents include a Tier 1 Exposure Route-Specific Objectives table that lists analytical compounds like Dieldrin, Arsenic, and Lead, with exposure thresholds for residential, industrial/commercial, construction workers, and soil-to-groundwater ingestion scenarios. The site appears to have contamination requiring careful environmental management, with specific pH and concentration limits for different exposure pathways. The plans are dated 2/6/25 and include a graphic scale, compass rose, and detailed soil boring/monitoring well locations, suggesting a comprehensive environmental remediation approach prior to the planned demolition and mixed-use site redevelopment.
