Storm Drain Master Plan - 2012


The first storm drainage system master plan for Billings Logan International Airport was completed in 1975. Updates to the original master plan were completed in 1989 and again in 1996.

The purpose of the 2012 Storm Drain Master Plan (SDMP) is to analyze the current drainage system at Billings Logan International Airport and determine what improvements can be made. This study will provide on-site recommendations for storm water conveyance and detention.
