Brush College Road Improvements for the City of Salem Public Works Department, Salem, Oregon.
ES&A staff led natural resources assessment and permitting for this project that involved three stream crossings and impacts to adjacent wetlands. ES&A coordinated agency input into new culvert design, conducted wetland delineation, prepared mitigation plans, a Biological Assessment, and USACE/DSL permits.

Metro Green Streets for Metro Regional Government, Portland, Oregon.
ES&A staff provided environmental requirements and constraints, as well as information on regional soils and hydrologic information. This Metro project that was funded by an Oregon Department of Transportation (ODOT) grant. Portions of this work include development of a Green Streets handbook that builds on the recently completed Creating Livable Streets guidebook. The Green Streets handbook is designed to provide acceptable design guidelines for situations where major street corridors or connectivity requirements conflict with protecting or restoring streams or wildlife corridors. The Green Streets handbook may also be used to address 4(d) "taking" provisions of ESA. The project also entails completing a demonstration project that tests proposed connectivity and environmental design proposals (from the Green Streets handbook) as part of the Pleasant Valley-Damascus future street plan. This element of the project must result in a future street plan for this urban reserve area that must address both future travel needs and stream protection.

SW Nyberg Road & I-5 Interchange for City of Tualatin, Tualatin, Oregon.
Perform background and field assessment, and prepare natural resource documentation for improvements associated with Nyberg Road/I-5 Interchange. ES&A will prepare a Natural Resources Assessment for Water Quality Sensitive Areas and Vegetated Corridors in order to obtain a Services Provider Letter from Clean Water Services. ES&A will assess potential impacts to steelhead and chinook salmon that occupy Tualatin River. In order to confirm and document that there will be no effects from the project to listed fish species, ES&A will prepare Biological Effects Determination.
