About Grayhawk

What the Sept. 16, 2026 storm meant for Grayhawk streets

On Sept. 16, 2026, storms dropped up to nearly 3 inches of rain in the northern parts of Scottsdale, Fire Capt. Dave Folio said. Scottsdale Road was closed between Grayhawk Drive and Deer Valley Road.

azfamily also reported about 2 feet of water that stranded three drivers on the Loop 101 on-ramp at Princess Drive. The report does not describe damage inside Grayhawk itself.

Heavy rain tests tile roofs, stucco walls and yard drainage. Walk the outside of the house after a storm and look for water against walls, stains on ceilings and damp garage floors.

The center of Grayhawk sits 15.3 miles from City Hall, and FEMA's flood map shows zone X there, a 0.2 percent annual chance flood hazard outside the Special Flood Hazard Area. Your own lot may sit in a different zone. For water that gets inside, see flood and storm damage.

Shared walls and floors: when a neighbor's leak reaches you

Grayhawk Development says the community has a broad mix of housing types. If your home shares a wall, ceiling or floor, water from the next unit can reach you.

  • Water follows the wall

    Water moves along pipes and drywall, so a stain can show up far from the source. A damp wall on a shared line can be a neighbor's leak.

  • Ceiling stains from above

    A brown ring on a ceiling under another unit or an upstairs bath can mean a leak overhead. Photograph it and note the date.

  • Dry the wall cavity

    Moisture can sit inside a wall after the surface dries. A moisture meter finds it. See structural drying.

Showers and tile at 20 years: what Grayhawk's age brings

The Census tract at the center of Grayhawk has a median build year of 2005, so a typical home there is about 21 years old. In that tract, 49.2 percent of homes were built from 2000 to 2009 and 21.4 percent from 1990 to 1999.

The tract covers more ground than Grayhawk, so treat these as tract numbers.

An IBHS study found that homes more than 20 years old were 37 percent more likely to have shower water damage. More than half of shower incidents involved a faulty shower pan. The study is national in scope.

A shower pan sits under the tile and catches water. When it fails, water goes into the floor and the wall below. Watch for loose tile, a soft spot or a stain on the ceiling under a bathroom. Water that sits in a wall can grow mold, so see mold remediation if you smell damp.

Raptor, Talon and 31 miles of trails: irrigation near your walls

Grayhawk adjoins the Grayhawk Golf Club, which has two courses, Raptor and Talon. The developer also lists neighborhood parks and 31 miles of multi-use trails.

The City of Scottsdale runs two parks here. Grayhawk Park is at 20726 N. 76th St., and Thompson Peak Park is at 20199 N. 78th Pl.

If your yard borders a fairway, a trail or a common area, water that sits against a wall can soak in. Walk the lot line after the sprinklers run, and aim your own sprinklers away from the stucco. A damp band at the base of a wall or a musty garage can mean water has been sitting there.

Leak in a Grayhawk home? Steps to take first

Close the main valve, switch off power to wet areas and take photos. If the City of Scottsdale is your water provider, call its water line at 480-312-5650 for a leak before the meter.

    Close the main water valve

    Shut off the main valve to stop a pipe leak. If water is coming through a ceiling, shut it off before you go upstairs.

  2. 02

    Warn the neighbors

    If you share a wall, floor or ceiling, tell the neighbors so they can check for water too.

  3. 03

    Keep clear of power

    Leave wet rooms alone until the power to them is off. Lights and ceiling fans can be live under a wet ceiling.

  4. 04

    Photograph the damage

    If the water came from a neighbor, note the date and time you first saw it.

  5. 05

    Get the water out

    Extractors pull standing water out first. Then the walls and floors are dried. See water extraction.

Hard water at Grayhawk faucets and appliances

Scottsdale's 2026 water report puts hardness north of Chaparral Road at 13 to 17 grains per gallon, and Grayhawk sits about 11 miles north of that road.

Those figures describe Scottsdale Water customers only. The 2026 report does not say which neighborhoods get which source water, so check your bill.

The city's hard water fact sheet says scale can reduce the efficiency of some appliances and clog faucets and aerators. White crust on a faucet or shower head is scale. Wipe it away and check for a drip underneath.

Grayhawk water damage questions

Was Grayhawk flooded in the Sept. 16, 2026 storm?

The azfamily report names Grayhawk Drive only as one end of a road closure, on Scottsdale Road between Grayhawk Drive and Deer Valley Road. It does not describe damage inside the community.

A neighbor's leak damaged my Grayhawk home. What do I do?

Stop the water if you can, photograph the damage and note when you first saw it. Tell your neighbor and your insurance agent. Wet drywall and flooring need to be dried, and that work starts with pulling out the standing water.

How old are Grayhawk homes?

Grayhawk Development says the community opened in 1996 and completed build-out in 2004. About 24.0 percent of the homes in the tract at its center date from 2010 to 2019, after the developer's build-out.

My yard borders a fairway. Where should I look for irrigation runoff?

Start at the base of walls that face the course and at the lowest point along the lot line. Look for soggy spots, extra-green grass or a jump in your water bill, which the city lists as signs of an outdoor leak.
