Introduction

Herriman City has experienced tremendous growth over the last several years

Many new subdivisions and associated roads have been constructed in the City

Deterioration

The rapid growth and construction activity has exposed our roads to traffic and heavy loads, which in some cases accelerated the deterioration of our roads

InventoryCurrently Herriman City has as

an inventory of 17,821,898 SF of asphalt road.

A well implemented preventive Road Maintenance plan is needed to take care of our roads and keep them operative and functional.
