When rain falls, it has to go somewhere, and that somewhere is always downhill.

Rain falling in Clive eventually goes to Walnut Creek and eventually flows out of the watershed. Because the Creek and its tributaries are prone to flash flooding, all rain events are viewed very seriously. The City works to manage rainfall, commonly called stormwater, by accommodating it with best management practices for volume and flowage control such as flowage easements; detaining it in ponds and basins; slowing its flow with quality topsoil, rain gardens, and vegetation; and moving it through the storm sewers.

As the first metro community to hire a Water Resources Engineer and approve the Walnut Creek Watershed Master Plan, Clive Public Works is committed to stormwater activities that aim to improve water quality and reduce run off, flooding, and pollutants. Recently completed City projects meet those aims and include oxbow restoration, stream bank stabilization, wetland creation, and rain garden installations.

Responsibly handling stormwater for the watershed

“Stormwater is a resource to be managed”
Several aspects of the City’s National Pollutant Discharge Elimination System (NPDES) general permit align with the City’s goals including:
  • Public Education and Outreach at tabled events such as the CliveFest, the 2018 Home Show, and brochures displayed at City buildings
  • Public Involvement at meetings for projects, information, and planning
  • Pollution Prevention through regular Operations of the storm sewer and normal activities such as snow removal and concrete saw cutting.
