French Drain Installation in Mill Creek, WA
French drains, curtain drains and downspout tightlines in Mill Creek that collect water before it reaches the house and carry it to an approved outlet. Serving Town Center, Mill Creek Country Club, Heatherwood and Mill Creek East.
Why Mill Creek yards hold water
Glacial till over most of the city, with wet organic soils in the creek bottoms and around the wetlands. That is the root of most soggy lawns, wet crawlspaces and ponding patios we see in Mill Creek: water that cannot soak in perches on the hard layer and runs to the lowest point.
Gently rolling plateau with the North Creek and Penny Creek ravines cutting through it. Lots back onto greenbelts and native growth protection areas more often than not. Slopes push water onto the next lot down, and flat ground leaves it nowhere to go, so the drain route and the grade around the house matter as much as the pipe.
North Creek, Penny Creek and a network of wetlands run through the neighborhoods, and many of them sit inside recorded native growth protection easements that cannot be cleared. Where a drain can legally discharge depends on these features, so we plan the outlet first and the trench second.
