✍️ Sample LARE Questions & Answers
1. Which slope is considered the maximum practical limit for mowed lawn areas in landscape design?
Slopes up to 25% (approximately 14 degrees or 1:4 ratio) are generally considered the maximum for mowed lawn areas to maintain safe and effective mowing operations.
2. In landscape grading design, a 2% minimum slope away from building foundations is primarily intended to:
Positive drainage away from foundations at 2% minimum prevents water from pooling against structures and causing moisture damage.
3. Which design strategy best exemplifies the principle of ecological stewardship when managing stormwater on a large commercial site?
Bioretention cells and rain gardens mimic natural hydrology by infiltrating and filtering stormwater on-site, reflecting ecological stewardship.
4. Which approach does Low Impact Development (LID) primarily emphasize for managing stormwater?
LID emphasizes distributed, small-scale practices that manage runoff close to its source, mimicking pre-development hydrology.
5. Which soil amendment is most appropriate for improving the drainage of heavy clay soils in a landscape planting bed?
Coarse sand, when added in sufficient quantity (at least 50% by volume), improves drainage in clay soils by increasing macropore space.
6. On a stormwater management plan, 'INV EL' notation refers to:
Invert elevation (INV EL) is the inside-bottom elevation of a pipe, catch basin, or manhole, critical for ensuring proper drainage flow.
