Permeability of a space means the ratio of the volume within that space which is assumed to be occupied by water to the total volume of that space.
Compatibility means a condition in which land uses or conditions can coexist in relative proximity to each other in a stable fashion over time such that no use or condition is unduly negatively impacted directly or indirectly by another use or condition.
Turbidity means the cloudy condition of water due to the presence of extremely fine particulate materials in suspension that interfere with the passage of light.
Stability (7) means the standard deviation (1 sigma) of the variation of a particular parameter from its calibrated value measured under stable temperature conditions. This can be expressed as a function of time.
Degradation means a decrease in the useful life of the right-of-way caused by excavation in or disturbance of the right-of-way, resulting in the need to reconstruct such right-of-way earlier than would be required if the excavation or disturbance did not occur.
