​City of Colorado Springs STORMWATER CONSTRUTION MANUAL

Grading and Erosion Control Permit
A Grading and Erosion Control (GEC) Permit is required prior to clearing, grading, excavation, filling, and other land disturbing activities.  GEC Plans and CSWMPs must be developed and approved prior to GEC Permit issuance.

Requirements
Any private or public construction site with construction activities disturbing one or more acres, or construction activities that are part of a larger common plan of development or sale that disturb one or more acres is required to obtain a City GEC Permit. Construction activities are defined in the definitions section in Chapter 1 of the Stormwater Construction Manual.  

​Construction activities involving the following will also trigger the requirement for a GEC Permit:
  • Any grading or construction within an open drainage channel as determined by the review engineer.
  • Any time a Permanent Control Measure is constructed or substantially modified, to be defined as involving non-maintenance related activities.  Adjustments or modifications to the control structure plate will not trigger the requirement for a GEC Permit.
  • On any site as deemed necessary and required by the SWENT Manager.
Sites meeting the above criteria must control erosion and prevent the transport of sediment onto adjacent properties, public rights-of-ways, streets, storm drainage facilities, channels or any other public or private facilities.

When there is a change in ownership for a parcel covered by an active GEC Permit (e.g. single family residential lot(s) or individual commercial lot(s) within a larger development), the new owner must accept responsibility for compliance with the original GEC Permit for their parcel(s).  This is accomplished by obtaining an Associate GEC Permit.  Associate GEC Permit applications must be submitted to the Stormwater Enterprise for approval prior to initiation of construction activities on such parcels.

Permit applications are handled through the ACA Portal
