Decks · Carlsborg, Washington
Decks in Carlsborg should be planned against the actual side-sewer route and accessible components. A new platform or skirt can obstruct a cleanout or valve even when no footing directly touches a pipe.
Obtain the accepted utility information and ask Public Works and the designer what access must remain. A system map does not locate the private line or establish a suitable deck support position.

Deck building
Have the designer show the deck supports, skirt and stairs with the actual sewer components and any service area. Coordinate utility work that needs inspection before the deck closes access. If the records are incomplete, resolve the location with the responsible provider instead of assuming an access hatch will compensate for an unknown route.
Ask for the side-sewer plan and any needed locating, including private components outside the scope of a general map.
Include the platform, skirt and stair layout so retained valves and cleanouts can be assessed in the finished arrangement.
Where sewer work is part of the coordinated project, ask the utility provider and County when it must remain exposed and what can follow inspection.
Before work begins
Confirm the actual deck scope with DCD and the retained sewer access with Public Works. A building review does not substitute for locating the utility.
