Pavement Trench Cut Fee Study
Public Works Department
RiversideCA.gov
2 BACKGROUNDOPPORTUNITY
1. Consider a Pavement Trench Cut
Fee Study to assess and quantify
damage caused by trenching and
utility cuts on City streets
2. May lead to adopting a Fee
Schedule to recover costs
associated with trenching impacts
and reduce life of roads

3 BACKGROUNDBACKGROUND
1. Paving Moratorium was extended
from three to five years
2. GIS Paving Map
3. Pavement Management Program
incorporated regular street surveys
and Lucity software
4. Increased roadway investment from
$13 million to over $24 million during
the past 10 years

4 BACKGROUNDBACKGROUND
5. Assess truck volumes, cut-through traffic
concerns, & restrictions
6. Piloted Recycled Asphalt Material
7. Partnered with RPU to recommend on-call
contractor to repair roads and sidewalks
damaged by water line repairs
8. Continue to pursue best practices to help
preserve streets
9. Not New – Anaheim, Los Angeles,
Sacramento, Austin, Phoenix, San
Francisco, Kansas City, and many more
agencies have conducted these studies

5 BACKGROUNDROAD DAMAGE BY TRENCHING OPERATIONS
1. Water Intrusion places load pressure on pavement causing some of the gravel to become unstable – leads to cracking
2. Zone of Influence – lateral support becomes weak and unstable, can unravel toward the trench opening (caving in)
3. 90% compaction isn’t always achieved which leads to failing patches and rough roads

6 BACKGROUNDBENEFITS OF A PAVEMENT TRENCH CUT FEE STUDY
1. Conduct structural damage at multiple locations in the City. Would select different pavement classes (i.e.
Excellent, Very Good, Good, Fair, Poor, etc.)
2. Review the number of annual street opening permits
3. Structural evaluations would provide deflection
measurements and required overlay thicknesses. The study would provide the reduction in pavement life for various Pavement Condition Index scores.
4. Recommend a Utility Cut Damage Fee Schedule specific for the City of Riverside

9 BACKGROUNDRECOMMENDATION
That the Mobility & Infrastructure Committee
recommend that the City Council approve a Pavement
Trench Cut Fee Study to assess damage caused by
trenching in the roadways and sidewalk associated with
development and utility work to consider adopting a
fee schedule to recover costs from such damage.
