Classification and Role of Soil Types
Soil types on-site determine the land’s structural capacity, drainage properties, and suitability for industrial construction. Soil is typically classified into categories like clay, silt, sand, loam, or combinations, each with different engineering characteristics.

• Sandy soils provide good drainage but lower load-bearing strength
  
• Clay soils offer high stability when dry but may shrink or swell with moisture
  
• Loamy soils are well-balanced, making them favorable for general development
  

Impact on Construction and Site Development
The type and quality of soil affect foundation design, excavation costs, and long-term structural performance. Poor soil conditions may require special construction techniques or soil remediation.

• Weak soils may demand soil stabilization, deeper footings, or piling
  
• High water tables or silty soils can complicate drainage and stormwater management
  
• Rock layers or gravel beds may increase excavation costs but improve stability
  

Assessment Methods and Regulatory Considerations
Soil types are determined through geotechnical investigations, which include drilling boreholes, analyzing soil samples, and preparing engineering reports. These are often required for permitting and site design.

• Phase I/II Environmental Site Assessments may reveal contamination risks
  
• Soil maps and USDA/NRCS resources can provide preliminary data
  
• Local building codes may require certified soil tests for permitting and structural design
