Abstract
The need for infrastructure inventory has
existed for years. Requirements of the Metropolitan
North Georgia Water Planning District Plans, GASB34
and re-issuance of the National Pollution Discharge
Elimination System for Municipal Storm Sewer System
have brought the issue to the forefront. Gwinnett County
began collecting information for Storm Water
Infrastructure Inventory 15 years ago. The methods used
for data collection has changed many times over this
period. Changes in technology, hardware and software
have made the collection and maintenance of
infrastructure inventory easier and faster. Our program
has evolved over time; some of the things that were done
worked and some of them did not. This evolution has
gone from paper maps to a digital networked system that
can trace flow upstream or downstream from any given
point. Key factors in a successful program include data
dictionary development, method of collection and storage,
and the maintenance of the data set.
To date, Gwinnett County has collected information on
over 82,000 structures and 950 miles of pipe
