Consideration should also be given to the expected type of road reconstruction

<center>'''''''''Roadway resurfacing'''</center>
|
The grinding of the base and top asphaltic compound to some nominal depth from the existing road surface and allowing for approximately 15-30% spot base repair where required while maintaining the original vertical design of the road.
May also include:
• Repair or replacement of concrete curb and installation of sub-drains
• Repair of concrete sidewalks
• Adjustment and/or replacement of driveway aprons and sod

|
<center>'''Road Reconstruction'''</center>
|
Complete removal and replacement of the major ROW elements including the road base and asphalt surface, concrete curb, sidewalks, and can include reconstruction or replacement of the sub-surface infrastructure (hydro, gas, water main, sanitary and
stormwater infrastructure).
Another type of road reconstruction can include the conversion of a rural cross section roadway into an urban cross section. This typically includes the installation of storm sewers, complete base and asphalt replacement, concrete curb placement, sub drains under curbs, and catch basin placement.

<center>'''Road improvement for rural to urban cross section'''</center>
|
As areas urbanize or infrastructure is upgraded rural cross section streets may be converted to an urban cross-section with curbs, gutters and storm sewers. Upgrades are one of the most common and economic opportunities in which LID can be incorporated into roads.
|-
|
<center>'''Roadway Reduction'''</center>
|
A process in which the effective width or number of travel lanes contained in a crosssection is reduced in order to achieve system improvements. Roadway reductions can be used for traffic calming purposes, transit projects, alternative transportation strategies such as the interdiction of bicycle lanes, and pedestrian crossings. Through
the process of roadway reduction, areas of the ROW that were used for vehicular travel are converted to sidewalks, landscaped boulevards, and/or cycle lanes.
