People who love theater and live performances are familiar with the quiet anticipation before the curtains draw open and the overture begins, hearing the soft hum of audience whispers and the rustling as people flip through playbills. Meanwhile, in Rehoboth Beach, as Clear Space Theatre’s plans to build two new buildings on Rehoboth Avenue have been delayed, the wait has been anything but quiet as opposition from some community members prompted the city’s planning commission to reconsider the final approval of the design plans. This monthslong back-and-forth came to a final decision Friday when commissioners voted 5-3 to approve the plans under certain conditions. Once Clear Space confirms that the building inspector has the most current drawings and receives building permits, the theater company will be ready to go to bid.
