North Hillsboro Technology Park Local Wetlands Inventory Available for Review


The City of Hillsboro has completed a draft Local Wetlands Inventory (LWI) for the Hillsboro Technology Park located south of Highway 26, north of NE Evergreen, between NE Sewell Road and NE Brookwood Parkway. The draft LWI was compiled based on the City’s field work and other analyses performed by Pacific Habitat Services in December 2019 and January 2020. 


The City requested property owner permission to conduct field work in fall 2019. Where the landowner granted permission to access, Pacific Habitat Services made onsite observations and inspected soils, vegetation, and hydrology. Where property access permission was not granted, boundaries were based on available maps and surveys and, where feasible, field observations were taken from public right-of-ways or adjacent properties.

Public Review 

The formal public comment period for the draft Local Wetlands Inventory Report closed on June 19, 2020.

However, if you have questions or comments about the report, please feel free to email the Planning Department or call 503-681-6153.  

Next Steps 

This LWI effort will help the City satisfy state land use planning requirements, further document existing conditions, and facilitate future development. The Department of State Lands is also reviewing the draft LWI. Once approved, the City Council will adopt the LWI so that it becomes part of our Citywide Natural Resources Inventory.

The LWI does not directly dictate where development can or cannot occur. However, wetlands are regulated by state and federal laws. Prior to any development or related activities that impact wetlands, the landowner or developer would need to complete a more detailed wetland delineation and obtain applicable permits.
