Drainage & French drains in Buckley: what to know

Any trench that digs into a city sidewalk, curb, or gutter needs a right-of-way use permit first under BMC 13.35.060(1), and the traffic plan rule in BMC 13.35.190(2) applies to any street work. A trench that stays on the lot is not named in that list, but we confirm its path with city staff in writing before it is cut.

The stormwater facility chapter, BMC 14.40, covers how a facility is inspected and maintained. A French drain is not described as a facility in the text we read, so we ask the city whether a drain outlet tied into a city facility is subject to that chapter. Until the city replies, the outlet is planned to stay on the lot, and no outlet is sent onto a neighbor’s ground.

Permits and rules in Buckley

We map the wet area and the grade before the trench is laid out, we check whether the trench reaches a sidewalk, curb, or gutter, and we confirm any city-facility outlet with city staff in writing. A trench that crosses the right-of-way waits for its permit, and the traffic plan step is scheduled before any street work begins.

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

Questions from Buckley homeowners

Where may a Buckley French drain empty?

On the lot, spread across the ground, or into a city facility only if the city approves the connection. No outlet is aimed at a neighbor’s ground in our plans, and a street-side outlet waits for the city’s right-of-way answer.

Is a permit needed for a French drain trench in Buckley?

A trench that digs into a sidewalk, curb, or gutter needs a right-of-way use permit first under BMC 13.35.060(1). A trench that stays on the lot is a question we confirm with city staff in writing before it is cut.

Does a trench solve a soggy Buckley yard?

It depends on where the water arrives. A trench earns its place when surface water comes from a clear upslope source, so we map the grade and the wet area before recommending one.
