Street Division

DX8A5808 (Large)

A resourceful and responsive public service division that effectively and efficiently manages and maintains the City streets, alleys, and commercial corridors providing for a safe and efficient transportation system. 

 Who we are

Road Maintenance

The Street Division is responsible for the maintenance for city roadways. The crews take care of alleys, chip and fog seal, crack seal, potholes, roundabout, striping, snow removal, and right of way sign and weed removal, etc. 

Sweeping & Stormwater

The Sweeping Crews focus on sweeping main roadways before moving on to residential streets, which are swept an average of 3 times a year. Sweeping keeps dust down and debris out of the storm drain systems. Trying to schedule certain streets on certain days can be difficult due to sweeping being done in sections around the city, your patience is appreciated! Having low hanging branches and limbs from your curbside trees, shrubs and/or plants makes it difficult for our crew to sweep. This causes the sweeper to sit higher than usual and can cause damage  to mirrors, antennas, etc., which are costly in terms of repair. We ask you to please trim back vegetation.

Storm Drains 

The Stormwater Crew works diligently year-round to eliminate as much debris as possible from entering the storm drains. In cases were storm drain lines need to be cleaned out our crew uses a vacuum truck to suck out any debris that is sitting on the bottom of the catch basin. Storm drains are designed to handle normal water flow, but occasionally during heavy rain flooding may occur. Plugged or clogged catch basins can cause localized street flooding during rain events, keeping these clean and clear of debris helps in the functionality and minimizes water on the road and your property.


Signs are upgraded by zones, which follows chip seal. The sign crew responds to call in regulatory sign repairs. Miscellaneous sign repairs and special requests are addressed the last week of the month. 

Traffic Signals & Street Lights

The Street Division maintains a majority of the traffic signals and street lights throughout the city. The division's Electrical Signal Crew works continuously on maintaining traffic signals, school zones, HAWKS, pedestrian signals, school flashers and concerns in regards to street lights.

Traffic Signal Awareness

Frequently asked signal questions:

-Why did the signal change so quickly?

The City of Nampa has timed signals. They register vehicles going through. The majority of time the signal will run the complete cycle. If there is a time spacing between vehicles of approximately 3 seconds the signal will "Gap Out" terminating the green phase this can happen due to citizens on cell phones, or other distractions that will cause a 3 second pause.
