The Traffic Engineering Division maintains more than 1.5 million linear feet of pavement markings to help organize the movement of transit, vehicular, bicycle, and pedestrian traffic. These include white and yellow lane lines, stop lines, turn symbols, and bike lanes, and are re-painted annually to help ensure the markings are visible and well maintained following winter snow removal efforts.
The striping season traditionally falls between May and October, and is heavily dependent on the weather. Optimal painting weather is warm and sunny (ideally 70 degrees, low humidity, with a breeze). Cooler temperatures prevent successful paint application.
On average, the City uses approximately:
- 4,000 gallons of white paint
- 4,500 gallons of yellow paint
- 42,000 pounds of glass paint beads that reflect at night
The City paints on average:
- Approximately 1,700 arrow markings per year
- More than 1,000 stops bars and over 200 crosswalks per year
- Approximately 80 railroad crossings per year
- 880,000 linear feet of yellow pavement markings (skip, solid yellow, and double solid yellow)
- 520,000 linear feet of white pavement markings (skip and solid white)
- 100,000 linear feet of bike lane markings (skip and solid white)
