Concrete Services in Redmond
Redmond's residential market ranges from the older single-family neighborhoods around downtown to the newer subdivisions in Education Hill, Novelty Hill, and the Trilogy communities on the east plateau. The downtown-adjacent blocks have 1970s-vintage concrete approaching end-of-life; the Novelty Hill and Education Hill areas call more often for upgrades - stamped patios, decorative driveways, and foundations on recently developed lots.

Popular Concrete Services in Redmond
Tech-campus and commercial work
Light commercial and tenant improvement work in Overlake and along NE 36th Street generates demand for ADA-compliant paths, loading approaches, and slab pours. Short-term work in the street, including driveway and sidewalk replacement, goes through Redmond's Right-of-Way Use Permit.
Newer subdivisions and decorative concrete
Homes in Novelty Hill and Education Hill were typically built in the 1990s through 2010s. Many original slabs are still structurally sound, making resurfacing an efficient alternative to full replacement. Stamped patios, brushed driveways, and exposed aggregate walkways are the most common upgrade requests in these neighborhoods.
Building over the aquifer
Sand and gravel beneath Downtown, Avondale Road, and southeast Redmond hold groundwater that supplies 40% of the city's drinking water, and the city manages critical aquifer recharge areas around its wells; in CARA I, groundwater can reach a supply well within five years. Since June 28, 2025, temporary construction dewatering in the critical aquifer recharge area has been limited to utilities, elevator pits, and footings, and Redmond's grading code requires fill to be free of construction and demolition waste, including recycled concrete rubble and asphalt.
Permits in Redmond
Redmond's Development Services Center reviews and issues land use and construction permits, and most applications start with the city's Plan Review Online request form; a residential permit stays valid for 365 days, extended by each passed inspection. The Right-of-Way Use Permit, issued by the city's Right-of-Way Division, covers short-term work such as driveway and sidewalk replacement or modification, requires a site plan and traffic control plan, and may require a performance bond.
Redmond exempts sidewalks and driveways not more than 30 inches above adjacent grade, and retaining walls up to 4 feet from the bottom of the footing that don't support a surcharge. A clearing and grading permit applies, counted cumulatively over a year, at 7,000 square feet of clearing, 50 cubic yards of earthwork, a grade change of 4 feet or more, or 2,000 square feet of new or replaced hard surface, and work during the October 1 to April 30 rainy season needs a city-approved wet weather plan. The Shoreline Master Program covers Lake Sammamish, the Sammamish River, Bear Creek, and Evans Creek.
Redmond concrete FAQs
Do I need a permit to replace a driveway in Redmond?
Not a building permit for a driveway not more than 30 inches above adjacent grade and not over a basement. Replacing or modifying the driveway or sidewalk in the street needs a Right-of-Way Use Permit from the city's Right-of-Way Division, with a site plan, a traffic control plan, and possibly a performance bond.
When does grading need a permit in Redmond?
Redmond's thresholds are cumulative over a one-year period: clearing 7,000 square feet or more, earthwork of 50 cubic yards or more, any grade change of 4 feet or more, or 2,000 square feet or more of new or replaced hard surface. Work in critical areas, their buffers, or city right-of-way also needs a permit.
Why does Redmond restrict dewatering and fill?
About 40% of Redmond's drinking water comes from groundwater in the sand and gravel beneath Downtown, Avondale Road, and southeast Redmond. To protect it, the city limits temporary construction dewatering in its critical aquifer recharge area to utilities, elevator pits, and footings, and requires fill to be free of construction and demolition waste such as recycled concrete rubble and asphalt.
