Grades, Surfaces, and Cross-Slopes That Welcome
Continuity favors gentle slopes around five percent or less, consistent cross‑slope under two percent, and surfaces that are firm, stable, and slip‑resistant even after rain. Where asphalt would overheat, resin‑bound gravel breathes. Where roots rise, rubberized panels bridge gracefully, keeping wheels, canes, and footsteps predictable, comfortable, and calm.
