What initial site considerations should be taken for runoff management?

Effective runoff management begins with a thorough understanding of internal site conditions and perimeter management. This involves assessing the topography, soil types, and existing drainage patterns on the site, as these factors significantly influence how water will move across and through the land.

When evaluating internal site conditions, it is essential to identify areas that are prone to flooding or erosion, as well as locations where water naturally collects. Perimeter management is equally crucial as it includes planning for the site boundaries and determining how runoff from the site interacts with adjacent properties or natural systems. This integrated approach ensures that runoff is managed properly, minimizing potential environmental impacts and complying with local regulations.

Considering other options like the location of existing buildings, access to utilities, or the type of vegetation present is important for overall site planning but does not specifically address the immediate concerns of runoff management. Instead, internal conditions and perimeter management focus more directly on the hydrological behavior on site, which is essential for effective runoff control.
