The City of Roanoke has approximately 1,287 lane miles of streets. The purpose of street cleaning is to maintain public rights-of-way to create a positive image and promote safety and environmental quality throughout the city. This section of the Stormwater Division also collects animal carcasses reducing bacterial contamination and health concerns.

The overall schedule for sweeping the city streets is as follows:
- Clean each residential street monthly

This program uses vactor trucks to remove sediment and debris from the 7,593 existing stormdrain inlets and 422 linear miles of existing stormdrain pipe. This aids in reducing the floatables, like plastic drink bottles, sedimentation and other pollutant sources before they reach the 711 stormdrain outfalls that flow directly into the Roanoke River and its tributaries.
Annual Tons of Debris Removed from Stormdrains:
|319 tons||416 tons||235 tons||278 tons|
Inspecting the Stormdrain System
Internal inspections of the stormdrain pipe system use a CCTV camera to map the location of the pipes a well as identify potential problems underground.
Annual Miles of Stormdrain Pipe Inspected:
|25 miles||8 miles||21 miles||18 miles|
Mapping the Stormdrain System
Beginning in March 2015, the City’s stormwater crews are updating the stormdrain system map for each watershed using iPad data entry into the ArcGIS Collector App. GPS technology readily identifies stormdrain features including down/up pipe orientation, termination points and outfalls.
- Completed Watersheds: Tinker Creek, Glade Creek, Carvin Creek, Trout Run, and Peters Creek.
- In progress: Ore Branch
- Upcoming: Roanoke River, Mud Lick Creek, Murray Run, Barnhardt Creek, and Murdock Creek.
