Land & Drainage Alteration Permits


On July 1, 2004 Public Works Engineering became the administrative department for implementing the Land & Drainage Alteration Program (LDAP) for the City of Springfield. As an NPDES Phase II city, Springfield is required by provisions in the Federal Clean Water Act (CWA) to adopt rules regulating the discharge of pollutants into surface waters. Additionally, the City’s Grading ordinance was adopted July 28, 2003. The grading ordinance sets forth specific rules and regulations to control excavating, grading, and earthwork construction. This includes construction of fills and embankments; establishes the administrative procedure for issuance of permits; and safeguarding persons and property against unreasonable hazards resulting from uncontrolled grading and excavating practices.


All persons engaged in construction activities must implement Best Management Practices (BMPs for preventing and/or controlling erosion, sedimentation and other construction related impacts to water quality and the environment. A Land Drainage and Alteration Permit (LDAP) is required prior to any disturbance for constructions activities that:

  • Disturb an area one acre or greater in size
  • Disturb 50 cubic yards or greater
  • Occur within the flood plain, Willamette Greenway Overlay District or adjacent to identified Goal 5 resources

Sites that are exempt from the permit requirements identified above must achieve the same outcomes and are subject to the same enforcement action as permitted sites.


– No deposit or discharge of sediment onto adjacent properties or water features
– No degradation of water features due to removal of streambank vegetation
– No deposit of mud, soil, concrete, or other material into streets or storm drains
– No exposure of soil or stockpiles to stormwater runoff without containment
– No earth slides or mudflows shall leave the property; and
– No discharge of contaminants or hazardous substances from the site
