When must pre-rain event inspections occur?

• A. Within 24 hours in advance of predicted event
• B. Within 48 hours in advance of predicted event
• C. Within 72 hours in advance of predicted event
• D. Within 1 week in advance of predicted event

Answer: (B)

Preparing for a storm means verifying that erosion and sediment controls are in place and functioning before rain starts. The required window is within 48 hours before a predicted rainfall event, because this timing balances forecast reliability with staying close enough to the event to catch changes in conditions. If you wait too long, BMPs may be damaged or displaced before the rain begins; if you schedule too tight a window, forecast updates could narrow or shift the timing, making the inspection less effective. A 48-hour lead time gives you a practical, actionable window to fix any deficiencies and keep runoff and sediment controlled as the storm approaches.
