Tulalip Shores Beach Association Pipeline Replacement

Coffman provided structural and water engineering services for a pipeline replacement for the Tulalip Shores Beach Association. The project included the development of a Small Water System Management Program (SWSMP) manual in preparation for the application and award of a Drinking Water State Revolving Fund (DWSRF) construction loan. These low-interest construction loans are funded through federal and state money to cover capital improvements that increase public health and compliance with drinking water regulations.

The project was guided through the Section 106 cultural review process, SERP environmental review process, and a conditional use permit requiring a county hearing examiner’s meeting for construction approval. The project included a 208 lineal foot directional bore, 52,800 gallon concrete reservoir construction for improved system reliability, over 3,400 lineal feet of new distribution piping, and booster pump station improvements.
