Update Process

The county formed the Stakeholder Advisory Committee and the related Technical Advisory Committee specifically to help revise existing county stormwater ordinances, and help develop new code language to support future low impact development. Staff met with key stakeholder groups and held four community open houses in April to inform residents about changes to the county's stormwater ordinance and receive feedback regarding those changes.

The Clean Water Commission, appointed by the Board of Clark County Commissioners, has provided public oversight throughout the entire stormwater ordinance update.
