Proposed Stormwater Management Criteria Update, 2022

The City of Manhattan is considering the adoption of an updated Stormwater Management Criteria and related Standard Drawings and Specifications for stormwater infrastructure. These new documents, once finalized and adopted, would replace the existing Stormwater Management Criteria that have been in place since 1994.

In addition, the City is proposing to adopt updated Standard Drawings and Construction Specifications which, when finalized, would supersede those currently in effect.

The public comment period for these proposed changes will be open until Friday, November 4, 2022. Comments or questions regarding these proposed standards should be sent to Bill Heatherman, Stormwater Compliance Engineer, at or made by phone at (785) 587-4578. All comments to the standard are requested in writing.
