Site work for a water / sewer project in Tigard, Oregon. Working plans call for site work for a water / sewer project.

Based on recommendations from the 2018 Stormwater Master Plan, and results of the completed Tigard Triangle Stormwater Implementation Plan (CIP #94044), this project is first priority to implement from a series of projects needed along the full length of Red Rock Creek in Tigard. The project will create a sustainable creek, floodplain, and vegetated corridor cross section that can withstand and contain current and future predicted storm flows while providing habitat and shading for native fish and other species. It will protect and re-bury exposed sanitary sewer lines. Excess sediment deposited in the vicinity of SW Dartmouth will be removed and the stream and wetlands restored to reduce flooding and improve stream function. Some piped creek sections will be day lighted. The new creek corridor cross section will be designed to also accommodate as possible a future Red Rock Creek Trail. The project will be designed to meet Clean Water Services standards such that new and re-development in the Tigard Triangle and Hunziker areas may be able to reduce onsite stormwater detention requirements and instead pay a fee to provide some future reimbursement toward this and other Red Rock Creek projects. This project represents multiple projects initially identified in the 2018 Stormwater Master Plan (projects 502, 506, and part of project 501 adjacent to SW Dartmouth). Project is included City of Tigard Fiscal Year 2024-2030 Capital Improvement Plan. As of March 18, 2025, per owner, design team has been identified. Design is complete and a construction bid will be issued in April 2025. Construction expected to start in summer of 2025 and end Fall 2026. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
