2020 Design Standards Update

The City of Overland Park is considering updates to the Design and Construction Standards Manual. This manual governs design and construction requirements for public and private infrastructure in the City and was last updated in July 2017.

See the full drafted update in PDF format.

Significant proposed changes to the design standards include:

  • Updated requirements for use of plastic drainage inlets on private storm drainage system
  • Updated maximum size requirements for high density polyurethane storm drainage pipes on private systems.
  • Clarified design storm requirements for detention basin sizing.
  • Changes to detention vault systems to allow utilizing gravel void space for detention storage.
  • Updated value ratings for utilizing native vegetation for stormwater treatment credit.
  • Updated criteria for utilizing existing native vegetation areas for treatment credit.

Specification Changes

The City has reformatted all of its existing construction specifications. Major changes include:

  • Sections reformatted to follow KDOT standard specifications.
  • Additional sections related to private development.
  • Concrete sidewalks and sidewalk ramps combined.
  • Requirement for post-construction video for public storm sewers built by private development prior to initial acceptance.
  • Pavement subgrade review and changes to compaction, embankment, excavation and fly ash treated subgrade.

Traffic Impact Study Guidelines

The City has also developed new traffic impact study guidelines associated with land development projects. During the meeting, staff will outline the new requirements which will be implemented for projects that are submitting development plan and plat applications beginning on Feb. 1, 2021.
