Detention Basins Outlet
Stormwater utility structures that have been traced by the Town of Chelmsford Engineering Division employees from the Town Base Maps from 1988 located in an AutoCAD drawing location O:\Engineering\projects\GIS-Cadd\2008-drainage.dwg. This CAD drawing was then converted to GIS by an independent consultant, CGIS Mapping. This conversion took place from February, 2014 to September, 2014 funded by a Risk Management Grant from MIIA. Once drains are installed, rebuilt, repaired and/or inspected, this data can be edited to reflect the most current information. Elevations are based on NGVD 1929.
