Dear Valued Customer,  

This is a reminder that on Monday, Mar. 2 and Tuesday, Mar. 3, each day from 8 a.m. to 5 p.m., potholing crews will be working in your neighborhood to complete early preparation and planning work for a future Tualatin Valley Water District (TVWD) water main connection project. 

This work will take place in the public right-of-way along the unimproved section of SW 65th Avenue, between SW Walnut Terrace and SW Wilbard Street.  Please see the map below showing the work area. 

Crews will be performing potholing to gather accurate information about underground utilities and site conditions. Potholing consists of minor digging in the ground to find nearby utilities for design work. These holes will be filled with temporary asphalt or dirt to match the surrounding area the same day. 

Purpose of Work  

This information will be used to design a future project that will install approximately 510 feet of new 4-inch water main within the public right-of-way along SW 65th Avenue. Completing this work now will help shorten construction time in the future and reduce impacts to the neighborhood and overall cost of the project. 

During this work, vehicles and equipment may be temporarily staged on the following streets: 

Using the information collected, engineers will design and permit the 65th Avenue Water Main Connection Project, which is expected to begin in summer 2026. 

Construction of this project will include a directional drilling method, which allows crews to install the water main underground without digging a continuous underground trench. 

Work will likely begin from a launch pit near SW 65th Avenue and SW Radcliffe Street. Drilling equipment will then create an underground path to a receiving pit near SW 65th Avenue and SW Wilbard Street. Once complete, the new water main will be pulled through the bore and connected to the existing system. 

TVWD will share advance notice and clear information well before project construction begins this summer, including: 

This upcoming project will improve water reliability, support emergency preparedness, modernize aging infrastructure, and help maintain stable water pressure for fire protection.

Thank you for your cooperation as we plan to make important improvements to your neighborhood’s water system.
