Concrete Services in Stanwood
Stanwood took its present form in 1960, when Stanwood and East Stanwood consolidated because neither town could afford new wastewater facilities on its own. In the 1990s a third business district was built on the hill, and large subdivisions were allowed in annexations north and east of the original towns. The housing stock shows it: only 28 percent of homes were built before 1990, and about two-thirds were built between 1990 and 2009.

Popular Concrete Services in Stanwood
Delta soils and the floodplain
The city says Stanwood is in the AE flood zone with a 13-foot base flood elevation, and downtown from the western city limits to Pioneer Highway is in the floodplain. Downtown sits on river alluvium and estuary deposits of soft or loose silt, clay, and sand with some peat and shallow groundwater, while the East Stanwood Plateau is glaciomarine ground. Any fill, grading, new construction, or alteration within the municipal floodplain needs a Floodplain Development Permit, which carries no fee. Slabs and foundations on the delta need more base work than lots up on the plateau, and wet-season scheduling matters; see the winter rain pours guide.
Dikes and flood works
The city owns and operates dikes, flood gates, and pump stations. The four-mile Skagit Bay Dike protects Stanwood and 1,800 acres of surrounding farmland from Puget Sound. The Stillaguamish Flood Control District, formed in 1993, takes in 6,040 acres south of the city limits with 30 miles of sea dikes and river levees.
Permits in Stanwood
The Community Development Department processes building, land use, and construction permits from City Hall at 10220 270th Street NW. Construction in or alteration of any public street, sidewalk, or alley needs a Right of Way Use/Construction Permit, and WSDOT approval is also required when the site is next to a state route. The 2026 fee schedule lists $318 for a residential driveway in the right-of-way and $318 for driveway expansions or alterations outside it. City standards require driveways of portland cement concrete or hot mix asphalt, residential widths of 10 to 30 feet, and drop-curb driveways where there is curb and gutter.
Land clearing, fill, and grade permits are required for construction projects over 50 cubic yards or within 2 feet of a property line. Retaining walls over four feet high, or walls in unstable soil, must be designed and stamped by a professional engineer and need a building permit, and a rock wall over 30 inches high in a fill section needs a geotechnical engineer's design. The city will keep using the 2005 Stormwater Manual because of local soil conditions and limited infiltration capacity.
Stanwood concrete FAQs
Does a driveway project in Stanwood need a permit?
Often. Stanwood's 2026 fee schedule lists a $318 driveway permit for driveway expansions or alterations outside the right-of-way and the same fee for a residential driveway in the right-of-way. Work in a public street, sidewalk, or alley needs a Right of Way Use/Construction Permit.
When does a retaining wall need an engineer in Stanwood?
City standards require walls over four feet high, or walls built in unstable soil, to be designed and stamped by a professional engineer, and those structural walls need a building permit before construction.
Is my Stanwood property in the floodplain?
Downtown lots are. The city says downtown from the western city limits to Pioneer Highway is in the floodplain, in the AE flood zone with a 13-foot base flood elevation. Any fill, grading, new construction, or alteration within the municipal floodplain requires a Floodplain Development Permit.
