Concrete Services in Mountlake Terrace
Mountlake Terrace is a south Snohomish County city between Lynnwood and Lake Forest Park, made up mostly of established single-family neighborhoods whose original driveways, patios, and front walks are now decades old. Water shapes much of the city: Lake Ballinger is its only regulated shoreline, and most neighborhoods drain to Lake Washington through the Hall Creek and Lyon Creek systems.

Popular Concrete Services in Mountlake Terrace
Driveway and patio replacement
Typical Mountlake Terrace projects are tear-out-and-replace jobs: a driveway that has cracked across its joints, a patio heaved by roots, or a front walk that holds water. Because the street end of a driveway is city right-of-way here, a replacement that changes the curb cut or apron also involves a city permit, so it helps to plan the private slab and the approach together. If the concrete is still sound, slab leveling may be enough; see leveling vs. replacement.
Lake Ballinger, Hall Creek, and Lyon Creek
Hall Creek runs from Hall Lake into Lake Ballinger, and Lyon Creek has an east and a west channel; both systems are part of the larger Lake Washington drainage basin. The ravine along the west branch of Lyon Creek is the main natural drainage channel for the area east of I-5. The city lists its geologic hazards as steep slopes, landslide and erosion hazards, and its location in Seismic Zone 3, which matters for retaining walls and foundations on ravine-edge lots.
Permits in Mountlake Terrace
Mountlake Terrace issues its own permits through the Community & Economic Development department, using the city's eTRAKiT online permit portal, and its critical areas rules are in the city's own code, MTMC Chapter 16.15. Curb cuts, driveways, and sidewalks in the street are Type B work under the city's right-of-way use permit (MTMC 19.95.070), which requires a street invasion deposit at issuance and a certificate of insurance, and the city's engineering permit list also includes a separate driveway permit.
On the private side, the residential permit checklist triggers stormwater and low-impact development review at 2,000 square feet or more of new plus replaced hard surface, or 7,000 square feet of land disturbance. A lot with wetlands, steep slopes, or a stream on site or within 200 feet needs a critical areas checklist, and work in a geologic hazard area, which includes all slopes of 40 percent or more, requires a geotechnical study.
Mountlake Terrace concrete FAQs
Do I need a permit to replace a driveway in Mountlake Terrace?
For the part in the street, yes. Curb cuts, driveways, and sidewalks in the city right-of-way are Type B work under the right-of-way use permit in MTMC 19.95.070, and the city takes a street invasion deposit when the permit is issued. Mountlake Terrace also lists a separate driveway permit among its engineering permits, so ask the permit counter which one applies before you schedule the pour.
Does a retaining wall need a permit in Mountlake Terrace?
The city publishes instructions for wall, retaining wall, and rockery permits, which are applied for through its eTRAKiT portal, but it does not post a simple height exemption on those pages. Check with Community & Economic Development before building one, and if the lot has steep slopes or other critical areas on site or within 200 feet, include the city's critical areas checklist.
What extra rules apply near Lake Ballinger?
Lake Ballinger is the only shoreline in Mountlake Terrace regulated under the state Shoreline Management Act, and the city's Shoreline Master Program covers land extending 200 feet landward from its ordinary high water mark. The current program was adopted in 2019.
