2011-2013 Stormwater Infrastructure Mapping Update Project
Work continues on the infrastructure mapping update project . As of the end of 2012, locations of all known manholes, catch basins, water valves and hydrants have been collected. See here for an example of what the draft data looks like. Additionally, elevation measurements of manholes in the Englesby Watershed have been collected for future modeling purposes. More recently, we have been converting our GIS data to the ArcGIS online environment so that we can make stormwater mapping data available to residents and engineers who are designing projects in Burlington. By harnessing the power of ArcGIS online we are also able to leverage the asset management of GIS in the field vs. using paper forms when doing inspections or inventory and then entering data later.
With the help of a new Stormwater staff member, we are making headway in resolving discrepancies in the area of the City with trickier mapping. Discrepancy resolution is a common step in these types of updates as there are places where it is not clear from the surface how infrastructure flows or is connected.
We have also set up a database associated with our GIS mapped features where inspection information collected for our infrastructure can be tracked through time. This is a very exciting component of the project as it will allow us to better prioritize our maintenance activities.
As part this project, several divisions within the Department of Public Works, along with the Department of Parks & Recreation pooled funding to acquire a highly accurate GPS unit so that we can continue to collect additional points that were not located during this update and can collect new points as they are added (new manholes, hydrants etc).
This project is made possible, in part, due to a grant from the Vermont Agency of Transportation which reimburses the City for 80% of its costs, up to $80K.
