The useful life-span of both concrete and asphalt streets can be extended through a variety of street repair and preventative methods.
The City's budget for street renovation is sufficient to pay for ongoing maintenance needs:
Preventative Crack Sealing: Although aesthetically unappealing in the eyes of some, preventative crack sealing is a cost-effective way to fill pavement cracks caused by ultra-violet rays and bad weather with a hot, rubberized asphalt so that water does not enter the base and cause extensive damage.
Asphaltic Mill and Overlay: This is a method whereby an inch and a half layer of new asphalt is laid over existing pavement and rolled to a smooth finish for a new driving surface that typically lasts 7 to 12 years, depending on road usage.

Eventually streets will fail, requiring reconstruction. Due to the high cost associated with street reconstruction, these are funded by the City issuing debt.
Given this limited budget, the City has developed a priority plan to identify a limited number of streets for reconstruction. Streets targeted for reconstruction are brought forward every four to five years as a bond issue.
