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 program reduces 1264 tons of sedimentation from the streets annually. 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 once every three months
Clean arterial streets monthly
Clean the Central Business District (downtown) streets nightly
This program uses vactor trucks to remove sediment and debris from the 8664 existing stormdrain inlets and 219 linear miles of existing stormdrain pipe. This best managment practice (BMP) aids in reducing the floatables, like plastic drink bottles, sedimentation and other pollutant sources before they reach the 418 stormdrain outfalls that flow directly into the Roanoke River and its tributaries. Crews also have a CCTV Camera that can be used to identify and gain more information on any stormdrain and pipeline issues, including investigating illicit discharges.
Mapping the Stormdrain System
The city’s stormwater crews are updating the stormdrain system map and concurrently assessing the state of the city’s gray infrastructure using iPad data entry into ArcGIS Collector App. GPS technology readily identifies stormdrain features including down/up pipe orientation, termination points and outfalls.
Mapping of the Lick Run watershed began in March 2015 and was completed July 1, 2015. Tinker Creek, Glade Creek, Carvin Creek was completed in December 2016. Trout Run is currently being mapped in 2017. Subsequent mapping projects will include: Peters Creek; Roanoke River; Mud Lick Creek, Murray Run, and Ore Branch; Barnhardt Creek; and Murdock Creek.
