Assess ability to design a rain garden for a residential property to manage stormwater runoff. Test scope includes site assessment (topography, drainage patterns, soil texture and infiltration rate, setbacks), sizing and storage calculations using impervious area, rainfall depth and runoff coefficients, selection and placement of appropriate native and moisture-tolerant plants, inlet/overflow/outlet design and erosion control, maintenance needs, and permitting/code considerations. Items will require applying calculations, interpreting site data, and producing a practical, safe, and low-impact garden layout and plant list.
