Basement waterproofing in Woodinville: what to know

A wet basement can have more than one source, and the footing drain is only one of them. We check the downspouts, the grade along the house, and whether a neighbor’s runoff reaches your foundation. Once the source is clear, we choose a repair that matches it, whether that is a footing drain, a regraded yard, or a relocated downspout line.

Excavation is where the earth-moving limits matter. Earth movement of 25 cubic yards or more on an R-1 through R-8 lot falls outside item (a) of the exemption in WMC 21.82.110(2), and a trench for utilities that needs a right-of-way permit is exempt under item (c). We look at the outlet first, since a discharge into a storm line is one we confirm with the city.

Permits and rules in Woodinville

We confirm a foundation dig against the earth-moving limits and the disturbed-area limit, and we check where the discharge goes. Whether a drainage connection needs approval is a question the code sections we checked do not settle, so we ask the city before the trench is dug. The outlet and the right-of-way get checked for your address before the ground opens.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

How we approach it

Walk the downspouts and grade before any ground is opened
Find out whether neighboring runoff reaches the foundation
Measure the earth to be moved against the 25 cubic yard limit
Confirm the discharge point before any pipe is connected

Questions from Woodinville homeowners

Why does water reach a Woodinville basement after storms?

We check the surface sources first, roof runoff and grading that slopes toward the house, and then look at the footing drain. The source decides the repair.

Can I connect my footing drain to a Woodinville storm line?

Whether a footing drain may tie into a city storm line is a question we confirm with the city before anything is connected. We also check the discharge point on your lot.

Does a Woodinville foundation dig need a review first?

It can. Earth movement of 25 cubic yards or more on an R-1 through R-8 lot falls outside item (a) of the exemption, and a connection to a city storm line is one we confirm with the city before the ground is turned.
