Why Stanwood Properties Need Professional Drainage
The soils in the Stanwood area are primarily derived from glacial parent materials, including glacial till, glacial outwash, and lacustrine deposits. These soils can vary from shallow, scoured areas with exposed bedrock to thick deposits, and some alluvial soils may have a seasonally high water table or be underlain by glacial till, which can contribute to poor soil absorption.
Elevations in Stanwood range from 2 feet above sea level near the Stillaguamish River to 190 feet in the northeastern hills. The terrain includes low-lying floodplains, tidal marshes, and hills, with the city located at the mouth of the Stillaguamish River.
In January 2026, a king tide combined with wind and waves overtopped and severely eroded a half-mile stretch of the century-old earthen levee protecting Stanwood and nearby farmland from Skagit Bay. The Stillaguamish River also poses a flood risk to low-lying areas near Stanwood during heavy rain events. The City's Stormwater Division manages 35 miles of conveyance infrastructure and requires routine inspection and cleaning of catch basins, ditches, and stormwater ponds. The city operates under the Western Washington NPDES Phase II Municipal Stormwater Permit and is updating its Stormwater Comprehensive Plan.
Stanwood is uniquely situated at the mouth of the Stillaguamish River and is protected from Skagit Bay by a century-old earthen levee. The area includes critical tidal marshes that serve as nurseries for endangered Chinook salmon, which complicates levee repair and flood mitigation efforts due to strict environmental regulations.

Stanwood Drainage FAQs
How much does drainage cost in Stanwood?
Residential drainage projects in Stanwood typically range from $3,000 to $14,000 depending on the system type, property size, and soil conditions. We provide free on-site estimates with transparent, detailed pricing — no surprises.
Why does my Stanwood yard stay soggy all winter?
The soils in the Stanwood area are primarily derived from glacial parent materials, including glacial till, glacial outwash, and lacustrine deposits. Combined with 35-37 inches of annual rainfall mostly falling between October and May, yards without proper drainage systems become saturated for months. A French drain or catch basin system can remove this trapped water.
Does Stanwood require permits for drainage work?
Most residential drainage installations in Stanwood do not require a permit unless they connect to the public storm system or involve significant grading near critical areas. Our team advises on local requirements during the free estimate process.
What drainage system is best for Stanwood soil?
The best system depends on your specific property conditions. Stanwood's soil varies by location, so we conduct a thorough site assessment during our free estimate visit to determine whether French drains, catch basins, regrading, or a combination will work best for your property.
