Spring Valley, Nevada residents and neighborhood associations often seek traffic calming solutions such as speed bumps or roundabouts to improve safety on local streets. This guide explains how requests are evaluated under Clark County traffic rules that govern unincorporated areas including Spring Valley, who enforces those rules, what penalties or requirements may apply, and practical steps to apply, appeal, or report urgent hazards.

Penalties & Enforcement

Traffic calming installations and changes in Spring Valley are governed by Clark County road and traffic regulations rather than a separate Spring Valley municipal code. Where the county code or engineering standards set requirements or penalties, the enforcing agency is Clark County Department of Public Works - Traffic Engineering. Specific monetary fines, escalation, or continuing-offence provisions are not always listed on public guidance pages; where the county code states a penalty it is cited below.

  • Enforcer: Clark County Department of Public Works, Traffic Engineering; inspection and complaint intake through the Public Works traffic page and online request forms.Traffic Engineering[1]
  • Fines: specific fine amounts for unauthorized alterations to roadways or failure to comply with traffic orders are not specified on the cited public guidance page; consult the county code for statutory penalties.Clark County Code[2]
  • Escalation and continuing offences: not specified on the cited public guidance page; the county code or enabling ordinance controls escalation, where published.
  • Complaints and inspections: submit a traffic concern or request for study through Public Works Traffic Engineering; officers or engineers will schedule field studies and speed/volume counts.
  • Appeals and review: appeals of technical determinations typically follow county administrative procedures; time limits for appeals are not specified on the cited guidance page and should be confirmed with the Traffic Engineering office.
  • Non-monetary sanctions: orders to remove unauthorized devices, stop-work orders, or court actions may be used where installations or behavior violate county rules.

The specific form name, number, filing fee, and submission method are not specified on the cited public guidance pages; contact Traffic Engineering for the current form and any application fee.Traffic Engineering[1]

How requests are evaluated

Typical county evaluation includes a field screening, collection of speed and volume data, collision history review, and consideration of emergency and maintenance impacts. Criteria commonly considered are measured 85th percentile speed, crash frequency, roadway classification, and proximity to schools or parks. If the street is a state route, Nevada Department of Transportation (NDOT) jurisdiction may apply and NDOT standards will control.

Traffic calming cannot obstruct emergency vehicle access and designs must meet county engineering standards.

Action steps

  • Gather signatures or documentation of resident support for the request.
  • Request a traffic study from Clark County Public Works via the Traffic Engineering page.Traffic Engineering[1]
  • If approved, coordinate design, permitting, and installation with the county; privately installed devices require prior county approval.
  • Pay any applicable fees as directed by the county; fee details are provided with the application or on request to Traffic Engineering.
