A combination of several factors are listed below that go into the selection process.
- Look at the utility condition of the street to see if it will likely be selected as a CIP project in the next 10-15 years. If it will be, then it is set aside for complete utility replacement prior to addressing the street. The City also tries to obtain grants to fund these projects if available. The last thing the City wants to do is pave a street and then immediately tear it up fixing utility problems. The goal is to have an overlay last 10-15 years.
- Last time the street had maintenance? Streets that haven’t been paved in over 20 years get a higher priority than more currently paved streets.
- Location plays a factor as well. The city tries to spread money throughout the City to make sure that we are spending money equitably and fairly throughout the community.
- Traffic impact plays a role in selection of streets. If they are heavier traffic routes or major thoroughfares in the city, they require more maintenance and provide better accessibility to users of the system for a majority of trips.
- Pavement and surface condition plays a role in the cost for repairs which impacts the number of streets and mileage of surfacing. The city does spend some money on poor condition streets but also spends some money on maintaining good to fair streets. The reason of spending money on good to fair streets is to preserve those streets from deteriorating and falling into extensive rehabilitation treatments which is costly to taxpayers. Based on the 2020 SIP program, streets that required rehabilitation, costed 44% more than maintenance overlays.
It is not a good financial strategy to select streets based on the worst first case scenario. If the City paved streets by the worst first strategy, the number of miles would severely decline due to extensive rehabilitation costs. Over time, this would have an adverse impact on the rest of the road network by not maintaining good to fair conditioned streets with lower treatment costs. If streets are not aggressively maintained, they could deteriorate and require extensive rehabilitation which costs taxpayers more in the long run.
