17-012 - Annual Assessment of Storm Drain System

The City of Johns Creek is planning to expand our annual assessment of the storm drainage system within the City’s borders. The City has a current Municipal Separate Storm Sewer System (MS4) inventory of the system in GIS and believes if covers the majority of the system and must inspect 20% of the MS4 a year. The public inventory includes 5,866 structures and 6,724 conveyances. The private inventory includes an additional 8,995 structures and 3,943 conveyances. This contract will be the first year to expand the program to include photographic records of the interior of pipes and structures.
