Springfield DPW
Development and Public Works Home Land Drainage and Alteration Permits (LDAP)

HISTORY

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.

 

 

OVERVIEW

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.

An LDAP permit is required prior to any site disturbance for construction activities that:

a) Includes grading that is intended to support a structure
b) Disturb an area one acre or greater in size or
c) Disturb 50 cubic yards or greater
d) Occur within the Flood Plain, Willamette Greenway Overlay Districts 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.
