In specific cases, depending on the project and its proximity, technical analysis for the Delimitation of a Specific Influence Area of natural underground cavities allows for detailing based on socio-environmental factors. This involves analyzing local environmental attributes to refine a minimum necessary area for maintaining and preserving the feature, different from the 250m radius defined by legislation. Physical, biological, sociocultural, and prehistoric factors are necessary approaches, providing more parameters than the arbitrary 250m radius initially defined as the influence area. Depending on the case, the project can adjust to a new delimitation.
