Concrete Overlays in Normandy Park, WA

Concrete overlays in Normandy Park: what to know

The city’s drainage chapter names overlays directly. Its trigger for added or replaced impervious surface excludes pavement maintenance, such as seal coats, overlays, and repaving of existing residential concrete or asphalt, unless the drainage patterns are substantially modified. A thin surface coat that leaves the slopes alone falls on the maintenance side of that line.

The carve-out has limits. Added thickness at a garage door, or a new pitch that turns water toward a bluff edge or a neighbor, changes drainage patterns. On sloped lots the movement question comes first: a slab that has crept toward a ravine or settled over fill will carry its cracks through a new surface.

Permits and rules in Normandy Park

An overlay on your own slab leaves the footprint where it is, and the critical areas code exempts maintenance and repair of single-family residences, driveways included, when no permit is needed and risk does not increase. The apron and sidewalk are right-of-way, where altering a driveway or sidewalk takes a permit. We look up how Community Development treats a surface coat on an apron before we quote.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

How we approach it

Keep the buildup thin enough that pitch and drainage patterns stay as they are
Gauge crack width at both ends of slabs near ravine and bluff edges
Stop the surface coat at the property line unless the city clears the apron
Settle wash water and slurry on lawn or in a bin, away from slopes

Questions from Normandy Park homeowners

Does resurfacing my driveway trigger drainage review in Normandy Park?

Usually not. The drainage chapter excludes pavement maintenance, including seal coats, overlays, and repaving of existing residential concrete, unless drainage patterns are substantially modified. Review also applies only when a city permit is involved. We tell you before work starts if your slab’s pitch would change.

My Normandy Park walkway is stained and pitted but flat. Is an overlay worthwhile?

Often, yes. Staining, pitting, and rough surface are what an overlay fixes, and a flat slab with stable cracks makes a sound base. A walk that has heaved at a root or settled toward a slope should be repaired or replaced first, because the overlay would follow the movement.

Can the sidewalk in front of my Normandy Park house be resurfaced?

Only with the city’s permission. The sidewalk is right-of-way, and altering a sidewalk, curb cut, or driveway there requires a permit. Lifted or broken panels need replacing, and a cut sidewalk is restored joint to joint. We ask Community Development whether a surface coat counts as an alteration.
