Prior to opening Stoddard Law Office in 2005 in Eau Claire, Stoddard practiced law in Madison with Ed Garvey, who was known, among other things, as the founder of Fighting Bob Fest, an annual event celebrating Wisconsin's progressive political traditions. For many years, Garvey and Stoddard, S.C. was one of the most influential civil rights and environmental law firms in Wisconsin.
As frac sand mining emerged and matured as an issue, Stoddard spoke frequently at public forums and helped educate concerned citizens and local officials about the tools available to regulate or deter frac sand mining. At at time when many area law firms cultivated ties to the ballooning frac sand industry, Stoddard was viewed as an independent, trustworthy community advocate and defender of the environment.
In relation to frac sand mining, Stoddard was probably best known for developing a nonmetallic mining licensing ordinance for Cooks Valley in 2008, an unzoned township in Chippewa County. After drafting what was then an innovative ordinance, he assisted in defending the town when it was sued by mining interests. In the 2012 landmark decision of Zwiefelhofer v. Town of Cooks Valley, the Wisconsin Supreme Court upheld the right of towns to regulate frac sand mining through such licensing ordinances. The ruling was a significant juncture in what remains an ongoing battle over the rights of local communities when confronting harmful land-use practices introduced by powerful corporate interests.
In addition to his work on frac sand mining issues, Stoddard also formed part of the legal team opposing the Gogebic Taconite Mine in the Penokees and he was involved in many other prominent environmental cases. Stoddard's obituary, which he wrote in his final days, was published in the Ashland Daily Press and the Eau Claire Leader-Telegram.
