Neighborhood Notice: Onsite Wetlands Review

Beginning the week of May 24, the City of Tigard's contractor (Pacific Habitat Services) will be onsite to conduct an environmental review. This work is part of a project to build a new water reservoir on the west side of Bull Mountain.

What you can expect through June 4, 2021

  • Contractors visiting the area during daylight hours.
  • Vehicles parked along Sunrise Lane.

What the contractors will be doing:

  • Confirming the location and size of wetlands onsite.
    • Contractors will collect data and leave flagging to delineate the boundary of two suspected wetland areas.
    • A map of the boundary and data collected will be submitted in a Report to the Oregon Department of State Lands and the US Army Corps of Engineers to confirm whether or not they will regulate the wetland areas.
  • The timeline for this data collection is approximately one week but the review by agencies could take several months.
  • This work will inform the project schedule and provide a better understanding of which agencies and permitting requirements will apply to siting of the reservoir.

What's Next

  • The city will hire a design-build team to construct a reservoir and pump station.
  • Technical analysis will determine the ultimate location of the reservoir, either at Cach Water site or Sunrise Park.
  • Construction is expected to begin in the winter 2023.
