Abstract
Embodiments of the invention provide automatically retractable screens, adapted for installation into a storm drain curb inlet, configured such that the automatically retractable screens are biased toward the closed position and thereby reliably closed during periods of no, low, or moderate surface runoff water flows, yet also reliably open when surface runoff water flow rates increase to moderate or high levels.
