Planning focus
Projection, slope concept, integrated gutters and surrounding site drainage interact.
Budget drivers
Integrated drainage systems can increase fabrication and maintenance cost.
Operations and lifecycle
Leaves and debris can create overflow and staining.
Safety and code boundary
Drainage design must fit local building/site conditions and should not create slip or icing hazards.
Educational planning only. Actual construction, code compliance, regulated systems, hazardous materials and safety-critical work require qualified professionals and current local requirements.
