Land & Drainage Alteration Permits

Development & Public Works

LDAP code changes are now official

The Oregon Department of Environmental Quality (DEQ) recently issued new requirements for Springfield about grading and erosion prevention under the LDAP. The City has updated sections of its Municipal Code to meet those requirements.

To receive updates about the code changes, sign up for Springfield’s emailed LDAP Updates.

Overview

All persons engaged in construction-related activities must implement Best Management Practices (BMPs) for preventing and/or controlling erosion, sedimentation and other impacts to water quality and the environment.

A Land Drainage and Alteration Permit (LDAP) must be obtained before starting any one of the following construction-related activities:

  • Disturbing 50 cu. yd. or more of material, and/or affecting drainage to or from adjoining properties.
  • Disturbing an area 500 sq. ft. or more in a sensitive area.
  • Disturbing 7,000 sq. ft. or more on any one lot, or across contiguous lots under the same ownership.
  • Disturbing one-or-more acres, whether at one time or in phases of development.
  • Resulting in any amount of cut or fill for placing an inhabited structure.

Sites that do not meet any one of the above requirements do not need an LDAP permit. However, they must still implement Best Management Practices to protect water quality and the environment, and they are subject to the same enforcement action as permitted sites.

LDAP Standard Requirements

  • 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.
  • No discharge of contaminants or hazardous substances from the site.

Entrances to construction sites are an area to consider for the LDAP.
