What is the primary consideration when assessing a building site and drainage?

The primary consideration when assessing a building site and drainage is whether the site has adequate drainage to accommodate a new structure. Effective drainage is crucial to prevent water accumulation, which can lead to various issues such as flooding, soil erosion, and structural damage. Proper drainage design must take into account the intended use of the building, the surrounding landscape, and local regulations to ensure that water is redirected away from the foundation and other critical areas.

While soil type and strata, climate and weather patterns, and proximity to existing infrastructure are also important factors in site assessment, they serve as secondary considerations in the context of drainage. For instance, soil type can influence drainage characteristics but is assessed after determining drainage needs. Similarly, knowing the climate helps predict drainage requirements but does not directly address the design of the drainage system for the new structure. Proximity to existing infrastructure can facilitate drainage options but remains less critical than ensuring the site is suitably drained for the proposed development.
