Standards & Design Requirements

The City of Des Moines requires street plans to conform to official engineering standards and subdivision regulations, including cross-section dimensions, pavement, curb, sidewalk, storm drainage, sight lines, and utility placements. Official design criteria and standard drawings are maintained by the City Engineering/Public Works office and apply to arterial, collector, and local streets. See the city engineering standards for drawing formats, required calculations, and minimum right-of-way widths.City engineering standards[1]

Early coordination with Engineering reduces re-submittals.

Process: Plan Review, Permits, and Approvals

Typical workflow for street layout approval:

  • Prepare preliminary plat and street layout showing alignment, ROW widths, grades, and utilities.
  • Submit complete plan set to Development Services for technical review and comment.
  • Address review comments, revise plans, and obtain approvals from Planning and Engineering.
  • Record plat and obtain any required right-of-way or encroachment permits before construction.
  • Construct improvements per approved plans and request inspections to obtain final acceptance.
Record plats and ROW permits are commonly required before issuing building permits that rely on new streets.
