The Engineer's Association of Nevada County (EANC) was founded in its present form in 1990 for the purpose of promoting awareness and appreciation of the engineering profession, earth sciences, and related fields, by keeping current on changing science and regulations, by encouraging students, and by honoring exemplary engineers and quality projects in the community.
Please help us by becoming a paid member of the association, and attending our monthly meetings. Membership dues fund our scholarships and outreach events, such as the local STEAM event and Lyman Gilmore's Flight Day.
Project and Engineer of the Year 2018
At a holiday luncheon at Grass Valley Brewery, the Engineer’s Association of Nevada County awarded the City of Grass Valley and Bjorn Jones the Project and Engineer of the Year awards, for the Little Wolf Creek Stabilization and Trails Project. In a case of truly making lemonade out of lemons, the city, Bjorn, Tim Kiser, and others have developed the sinkhole into a park/trailhead for the Little Wolf Creek Trail system. Kudos to the City of Grass Valley and Bjorn.
Little Wolf Creek Stabilization and Trail Project
The Little Wolf Creek Stabilization Project was born from a large sinkhole that developed during the major storms of January 2017. Catastrophic failure of the 96” culvert conveying Little Wolf Creek under Highway 49 and Freeman Lane resulted in a seventy-foot-deep by eighty-foot-wide sinkhole adjacent to the Liberty Motors (Tripp’s Auto Body) parking lot. Stabilization and repair efforts were undertaken over the course of 2017, while the disturbance and loss of use on the property led to property acquisition negotiations with Tripp’s Auto Body.
The concept of a Wolf Creek Trail Project has been a desire for many in the Grass Valley community for a number of years. In 2018, the City was finally able to design and contract for construction of Phase 1 of the Wolf Creek Trail from River Otter Way near the Wolf Creek Lodge on Freeman Lane, traversing approximately 1.2 miles north to the City’s Northstar Mining Museum property on Allison Ranch Road. By coincidence, the Little Wolf Creek Stabilization Project was located at the approximate midpoint of the proposed Phase 1 of the trail project. As part of the stabilization efforts, an access road was graded down the steep hillside from Freeman Lane to the creek which, with the recent approval of a purchase agreement for the property, will now serve as open space and a trailhead to the Wolf Creek Trail.
