  • Welcome to the Geo-Environmental Section

    sunset_image.jpgThe Geo-Environmental Section is responsible for coordinating environmental regulatory compliance for all transportation improvement programs in the state which use federal funds. The section is also responsible for statewide practices, standards, training, expertise, and asset management for geo, hydro, and environmental disciplines within ODOT.

    We protect the public and are stewards of the public interest for a variety of natural and cultural resources. We bridge the natural resources and civil engineering disciplines. We build dynamic partnerships for making vital decisions to serve the public and protect our resources.

Section Highlights


Stormwater Treatment Technology Center
State and Federal agencies, together with environmental organizations, have expressed increasing concern regarding the effectiveness of stormwater treatment devices and facilities in achieving water quality standards required by permits.  Transportation agencies are also facing continued uncertainty regarding the costs associated with maintaining these facilities.  As a result, transportation organizations are looking for tools and unbiased information that would support highest-return choices in the stormwater quality technology they invest in.  The purpose of the Stormwater Treatment Technology Center (STTC) is to provide designers and users, of stormwater treatment technologies with a tool to provide non-biased, credible assessments of the effectiveness and maintainability of stormwater treatment technology being considered for installation at their stormwater treatment facilities.
The concept for the STTC was developed by a group of stormwater professionals that ODOT convened to discuss the challenges and ways to improve the management of large stormwater programs.  The group included representatives from the Oregon Department of Transportation (ODOT), other state and local agencies, and the Washington Department of Ecology (WDOE).  Discussions over a two-year period revealed that WDOE and several other agencies had facilities or protocols established to evaluate pollution removal effectiveness of stormwater treatment devices; however, none of the existing facilities or protocols had the capability to demonstrate a long-term stormwater,  the maintenance required for the technology, the costs of maintenance, and at what point the technology would it fail and require replacement.
