We are wrapping up this City of Sumner facility as the city is getting excited to move into their new digs. Great job all!

We have completed the mass grading and built enormous retaining walls so the warehouse can be constructed. More piping needs to be installed as we wrap the waterline around the building for fire protection. The 33 acres site is a challenge in the wet winter months.

Mass grading has been completed, and large retaining walls have been constructed to support the future warehouse. Additional piping remains in progress as the waterline is extended around the building to provide fire protection. The 33-acre site presents ongoing challenges during the wet winter months. Project completion is anticipated around September 2026, weather permitting.

We are installing storm piping to collect the roof drain water and treat it so it can be discharged into the local streams in the area. Work is just getting started.

We are going to make an unsafe corner on this roadway much safer by opening up the site lines for traffic to see better. We will build a large retaining wall and plant some shrubs to make it look beautiful.

We are installing some new sanitary sewer facilities so the sewer flows more efficiently in the City of Issaquah. We are also going to re-line over 600 feet of sewer piping to extend the life of this critical infrastructure.

Utility work includes approximately 600 linear feet (LF) of new sanitary sewer, 500 LF of new water main, 150 LF of underground power installation, and associated grading and excavation.

Installed 5,370 linear feet (LF) of cured-in-place pipe (CIPP) lining within 6-inch concrete residential collector gravity sewer mains. The project included, but was not limited to, robotic reinstatement of sewer laterals, sanitary sewer bypass pumping, cleaning of existing 6-inch concrete sanitary sewer mains, and closed-circuit television (CCTV) inspection before and after rehabilitation.
