Stormwater Criteria

The City of Colorado Springs Drainage Criteria Manual (DCM) contains drainage criteria and submittal requirements for drainage studies and plans.  The two volumes of the manual are posted below.

Clarifications and minor modifications to criteria are documented in Policy Clarifications.  Where conflicts or differences between Policy Clarifications and the DCM exist, the Policy Clarifications shall apply.  All active Policy Clarifications are posted below.

Engineers are encouraged to check the website often for updates to criteria.  To sign up for notifications of updates to drainage criteria, please send an email to Stormwater Criteria.

Project specific questions related to the Drainage Criteria Manual should be directed to the project Review Engineer.  Questions related to drainage criteria that are not project specific should be directed to Stormwater Criteria.
