Drainage Issues

Residents may contact the Office of Highway Maintenance (OHM) for help figuring out who handles drainage issues.


The OHM does functional maintenance twice per year. This includes mowing, trash removal and clearing obstructions to the flow of water.


Responsibility of streams depends on its location.


We maintain the landscape of county rights-of-way. This includes:

  • Mowing of medians and side of roads
  • Clearing of brush
  • Storm drain channel and pond mowing

For more information please view our Mowing Program Fact Sheet.
