A self-made businesswoman and mother of three has died following an off-road vehicle accident close to her stunning seven-figure mansion.

Darcy DeBord, 51, was killed last Sunday when her utility task vehicle (UTV) overturned on a trail near her North Plains, Oregon, home, KOIN reports.

DeBord was riding alone at the time of the fatal crash and was declared dead at the scene close to her $1.9 million residence on NW Moreland Road.

She founded lifestyle boutique White Birch Design Company in 2017, according to its website.

The company started as a small venture in Hillsboro but had grown to include three locations in the Portland area as well as one in Vancouver, Washington.

Her loss is being mourned by her husband, Ben, and their three daughters, Jessica, Sydney and Morgan.

DeBord’s stores will remain closed through Friday, when friends and family will gather in Hillsboro, about 20 minutes south of North Plains, to remember her.

The stores are scheduled to reopen Saturday.

DeBord had just posted about the Vancouver store’s grand opening day on April 29, about four days before her death.

She was also on the executive committee of the Washington County Chamber of Commerce.

A customer of DeBord’s recalled her entrepreneurial success when asked about her death.

‘The store gets lots of business. It’s just such a beautiful place. They seem very successful,’ Kim Pruski-Dehnert told KOIN.

Pruski-Dehnert added that she was thinking of DeBord’s family ahead of Mother’s Day this week.

‘Just knowing who she is, the type of person that she is and what she’s built, and she has children, family,’ she said. ‘What an incredible loss.’

An obituary posted for DeBord by her company remembered her as having ‘a presence that lifted everyone.’

‘Birthdays, outings, girl trips and parties were numerous,’ it read. ‘Everyone knew her and everyone wanted to be around her.’

A Facebook post from last May said DeBord had just celebrated her 30-year anniversary with her husband Ben

DeBord’s crowning achievement was raising her daughters, according to the tribute.

‘Every day, they saw what it meant to be a strong, independent and amazing person,’ the tribute noted. ‘She was their role model and their teacher.’

DeBord began dating her ‘lifelong love’ Ben when she was 16 and married him at 21. The two celebrated their 30th wedding anniversary in May last year.

The obituary said DeBord’s company ‘started as an interior design business making people smile in their home’ before expanding.

‘Darcy liked being her own boss and her energy and spirit shone in every day that she was in one of her stores greeting a customer or setting a table full of fun,’ it continued.

The boutique had previously announced DeBord ‘passed away in an accident this past weekend,’ but did not mention specifics.

DeBord’s husband and daughters have not yet publicly commented on her death.

However, her cousin Chad Stafford shared an image of them on Tuesday, captioned: ‘RIP cousin! Until we meet again.’

Another local business, Résolu Cellars, said DeBord had the ‘vision and drive’ to put together their first tasting room and production facility.

‘She was a true champion of small business and local growth,’ the business said.

A separate home decor store, Nash & Nichol, also remembered DeBord as a ‘true friend’ who ‘offered her guidance, insight and years of experience in retail to us.’

‘This loss feels like a loss for the retail community, and we will miss her,’ their tribute read.

The Daily Mail has reached out to DeBord’s husband and daughters, White Birch Design, and the Washington County Sheriff’s Office in Oregon for further comment.
