Eric K. Nelson of Duvall was elected a King Conservation District supervisor in an internet-based election that ended Tuesday.

The results  for Board of Supervisors position two are Nelson, 1,292, Douglas “Bruce” Elliott of Kent, 820, Teri Herrera of Redmond, 129), Preston Prudente of Sammamish, 54, and four write-in votes.

In one of the first elections of its kind in the Unites States, King Conservation District’s 30-day online election began Feb. 15. The district also provided an “in-person” voting option at the district’s offices on the final day of the election.

The district is headquartered in Renton.

The unofficial election results from the district-wide election will be certified by the Washington Conservation Commission at its business meeting on May 16. Nelson, who will serve a three-year term, will be sworn in at the King Conservation District board of supervisors meeting in June.

The King Conservation District encompasses most of King County and delivers natural resources information and technical and funding assistance for stewardship efforts by landowners. It is one of 46 conservation districts in Washington state.

The election was conducted for the King Conservation District through election supervisor Election Trust of Bellevue and Scytl USA of Washington, D.C.

“The 2011 election was an important building block for future online elections held by the district,” said King Conservation District board of supervisors Chairman Bill Knutsen. “In the long term, we believe online voting remains the best option to broaden voter participation in the King Conservation District election process.”
