What does a site assessment checklist evaluate?

• A. Slope, soil infiltration, proximity to water, impervious area
• B. Number of employees
• C. Annual rainfall
• D. Color of asphalt

Answer: (A)

A site assessment checklist focuses on the physical features of a site that determine how water moves and how pollutants might be carried off the land. Slope influences runoff speed and erosion—steeper slopes usually produce more rapid runoff and more sediment transport. Soil infiltration rate shows how well water soaks into the ground; high infiltration reduces surface runoff, while low infiltration increases runoff and potential pollutant movement. Proximity to water is important because runoff containing sediments, nutrients, or chemicals poses greater risk to nearby streams, rivers, or lakes when the site is closer to them. Impervious area—the amount of hard, non-porous surfaces like pavement and roofs—prevents infiltration and increases both the volume and speed of runoff, making pollutant transport to water bodies more likely. Other options don’t fit because they don’t describe site features that directly affect runoff and pollutant transport: number of employees relates to operations, not hydrology; annual rainfall is a weather factor rather than a site characteristic; color of asphalt is unrelated to infiltration or runoff.
