About this dataset

This service represents CTDOT’s Stormwater Drainage Network. The data is collected from a collection of resources including completed construction plans, right-of-way plans, permits & field reconnaissance. Not all drainage features depicted on the map accurately reflect the condition of the drainage network that is currently built. Data is updated, modified and added daily by CTDOT to both grow the inventory of drainage structures statewide and to improve accuracy. Drainage data is collected for continued compliance of the CTDOT MS4 Permit and for CTDOT’s Asset Management Purposes. Please refer to the CTDOT Maintenance Guide for definitions of all Drainage Features: ctdot-ms4-gis-database-maintenance-guide-jan-2021.pdf
