Mobile Mechanic & Auto Detailing in McKinney, TX
McKinney is home to a planned US 380 freeway on new location, sits in a county that took the 2016 Wylie hail storm, receives NTMWD water that NTMWD calls moderately hard, and is covered by a state junked-vehicle law cities can enforce. Sources are named below. Tim serves McKinney.
The US 380 freeway plan and the US 75 lanes on TxDOT's lists
Two road projects show up in state paperwork for McKinney. For US 380, TxDOT issued a combined final environmental impact statement and record of decision that selects the Blue Alternative: a freeway built mostly on new location from near Coit Road, around the northern part of McKinney, and back to existing US 380 near FM 1827 and New Hope Road.
On US 75, an exhibit of previously approved projects attached to a Texas Transportation Commission minute order passed August 21, 2025 (Minute No. 117025) on the SH 121 funds work program lists entries to construct new roadway lanes on US 75 in McKinney, from north of US 380 to south of Bloomdale and from south of Bloomdale Road to Telephone Road. These are planning and funding documents, so check TxDOT for the current status of both projects before assuming anything about lane counts, schedules or closures.
The April 11, 2016 supercell and Wylie's hail
Wylie, in Collin County, has a documented case of what one afternoon and evening of hail can do. The National Weather Service in Fort Worth reviews April 11, 2016, when an intense supercell crossed North Texas roughly from Wichita Falls to Tyler. NWS says the hail was especially damaging in Wylie, where 80 percent of homes were affected and losses topped $300 million. It counts more than 50 severe hail and wind reports from the storm and says the event set a record for the largest hailstone in the NWS Fort Worth forecast area, at 5.25 inches.
The radar notes say the storm reached its maximum intensity after moving into Collin County, with an updraft over Wylie likely exceeding 100 mph. Earlier, near Sunset, Texas, radar signs pointed to hail up to baseball size. NWS also explains why no tornado formed: a shallow cold front undercut the storm. The 5.25-inch stone is not the Texas record, though: NWS says stones of 6 inches have been reported in Moore and Ward counties. Wylie is not McKinney, and the NWS review does not describe McKinney damage, but it shows the scale of storm this county can produce. Insurance is covered in the first answer below.
Lavon Lake water and what NTMWD's 2024 tests show
The North Texas Municipal Water District says Lavon Lake, in Collin County, was the first reservoir the US Army Corps of Engineers built to serve its communities, and that it is still the district's largest source. Its 2024 water quality report says member cities and customers other than Bonham were served by the Wylie plant, and it lists the City of McKinney among the areas that also receive water from the Leonard plant. NTMWD's water quality reports page says the Wylie plant treats a blend of Lavon Lake and Lake Texoma water. Total hardness in the Wylie plants' 2024 results ran from 105 to 202 parts per million, and in the Leonard plant's results from 112 to 188.
NTMWD calls its treated water moderately hard, mainly because of minerals from Lavon Lake. It says those minerals pose no harm to health but can leave spots on clean dishes and lime scale on fixtures once the water evaporates. On a car, evaporated minerals show up as the water spots covered in the second answer below. The City of McKinney's own water quality report shows what reaches your tap.
Collin County snow and the brine that goes down ahead of it
Winter has its own history here. NWS notes that a very localized heavy band dropped 5 to 9 inches of snow across Collin County on March 20 and 21, 2010, while some spots about 20 miles to the southwest picked up only 1 inch. Ahead of a January 2026 winter storm, the Dallas Morning News reported that TxDOT and the North Texas Tollway Authority began pretreating major highways, bridges and overpasses across North Texas. NTTA said it would treat more than 1,200 miles of roadway, and a TxDOT spokesperson described the usual mixture as a sodium chloride brine plus sand and chat.
Consumer Reports says road salt accelerates rust that can damage braking, steering, suspension and fuel-system equipment. Its experts advise a monthly wash during snow season, more often if the car is coated in salt, with an undercarriage spray and attention to the wheels.
A car that will not run and the state junked-vehicle rule
Texas Transportation Code Section 683.071 defines a junked vehicle as a self-propelled vehicle that is wrecked, dismantled or partly dismantled, or discarded, or that has been inoperable for more than 72 consecutive hours on public property or more than 30 consecutive days on private property. For motor vehicles, the subchapter applies only to one that displays an expired license plate or no plate. Section 683.074 lets a municipality or county adopt procedures for removing junked vehicles as a public nuisance, so what applies at your address depends on what McKinney has adopted. Ask McKinney Code Compliance.
McKinney's own cleanliness-of-premises article, Chapter 70, Article III, was amended by an ordinance the City Council passed on August 16, 2022. That text defines junk to include used vehicle components and parts not currently in use, and it declares it a nuisance to let junk accumulate on property. Pulled parts left in a driveway can therefore be a separate question from the car itself, and Code Compliance can say how the city treats them. Municode may carry later changes, so confirm the current wording with the city. This page is not legal advice.
