Erosion Prevention and Construction Site Management Program 

On Oct. 16th, 1996, the City adopted the Erosion Prevention Ordinance (20067). The ordinance was designed to restrict the discharge of sediments or other construction related materials, including hazardous substances into the City's stormwater system (Eugene Code 6.625). In Dec. of 1996 the City Manager adopted Administrative Rules (R-6.645) to implement the ordinance.

In July of 1997, the City of Eugene signed a Memorandum of Agreement with the Oregon Department of Environmental Quality to assign and monitor 1200-C permits within the City limits.

On May 25th, 2004, the City of Eugene entered into an intergovernmental agreement with Lane County to administer and enforce the Erosion Prevention and Construction Site Management Program (Eugene BMP E-2 Exhibit “A”) outside City limits but inside the City of Eugene Urban Growth Boundary. The Stormwater IGA has been amended several times to extend the timeline and remains in effect.

On December 12, 2016, the City adopted the Erosion Prevention Ordinance (20570) amending the code to include additional actions that require an erosion permit. The following are the current thresholds to obtain an erosion permit

  1. Disturbs one or more acres of land by one or more phases of development, and the disturbance is located on the same parcel of land or on contiguous parcels of land under the same ownership;
  2. Is located in a sensitive area and disturbs 500 sq ft or more. Sensitive area defined as: when the slope of the parcel is greater than 10%; or the site contains highly erodible soils; or the parcel or tax lot of record has the potential to directly drain into a water feature or its designated buffer area); or
  3. Disturbs more than 5,000 cubic feet of material during one or more phases of development.
  4. The Stormwater Management Manual Section 4.8 also requires sites with known or suspected contamination to obtain an erosion permit.
