Crews started laying down chip seal in several local neighborhoods today with work set to continue through the weekend before it wraps up early to mid next week.
The City conducts much of its planned street maintenance between April and the end of June each year when the pavement temperatures are warm enough but before the summer monsoon rains arrive. This year crews are applying chip seals to the same areas that received crack seals last year, completing a cost-effective maintenance strategy that extends the life of a road for five to 10 years.
This is all part of an annual street maintenance program that is informed by a Pavement Condition Index Survey completed two years ago. The data from this survey enables City staff to plan projects for the next several years so that they use available resources in the most cost-effective manner to get the most bang for the buck in maintaining the City’s streets.
“The pavement condition index is an invaluable tool to ensure we can coordinate and plan street maintenance efforts to maximize the use of our available resources,” Public Works Director Sharon Flissar says.
Where is the chip sealing being done?
Chip sealing work is being completed on neighborhood streets in the following areas, also detailed in the maps provided here (click the maps to enlarge them):
- On about 16 streets located off of 7th Street north of Tacoma Street and south of the Highway 90 Bypass.
- On Highland Drive and Prairie Street.
- On St. Andrews Drive between Buffalo Soldier Trail And Player Avenue, and on about a dozen small streets in that neighborhood.
What is a chip seal and why do you use it?
The City uses crack seals and chip seals to extend the life of local streets before they deteriorate to the point when a thin overlay or even a full rebuild of the street is required.
By completing a crack seal last year and following it up with a chip seal this year, the City is able to extend the life of these streets significantly at a relatively low cost.
My street is in worse shape than the ones you’re working on, why are you not fixing it?
When a street’s condition gets too bad for a crack seal and chip seal, a thin overlay or even a full reconstruction is required.
These types of projects are significantly more costly, so the City makes every effort to prevent streets from reaching that point as long as possible.
To be cost effective, the City packages together a variety of similar projects into its street maintenance effort each year. So in certain years, the City will do crack seals or chip seals and in others the City will tackle multiple overlays or rebuilds.
Just because your street is not getting attention this year, does not mean it’s not part of the longer term plan.
How do I report a pothole or other streets issue?
The City of Sierra Vista’s streets crews conduct small emergency spot repairs as needed year-round.
If you observe a hazard that needs urgent attention, please contact the Public Works Department by calling (520) 458-5775.
How do I report an issue on a state highway?
Not all local roadways are maintained by the City, with the Highway 90 Bypass and Highway 92 being prime examples.
Issues on state highways can be reported to the Arizona Department of Transportation by using an online form at apps.azdot.gov/contact_adot/ or by calling (602) 712-7355.
If an issue is on a private street, the City’s Community Development Department can work with the property owner to ensure the issue is addressed. Issues on private streets may be reported to the City’s Code Enforcement staff by calling (520) 417-4413.
