The Lyon County Board of Commissioners will be presented options to implement the Dayton Area Storm Drain Master Plan at the February 4th Board of Commissioners meeting. Lyon County, Storey County and the Carson Water Subconservancy utilized FEMA grants to study, map and engineer solutions to the long term problem of storm drainage flooding. In 2020 the Board of Commissioners was presented the plan and directed County Manager Jeff Page to move forward with developing a plan to implement the study.

The Board of Commissioners will be provided three options to create a special district to manage the building and maintenance of the infrastructure to reduce the effects of storm drainage flooding. In the past 25 years portions of Dayton, Moundhouse and Silver City have been severely hit with flash flooding. County Manager Jeff Page explains that the goal is to develop a district and funding stream to address the issue in phases. It estimated that the cost to fully implement the plan is $80,000,000.00.

Currently the Lyon County Road Department and the Lyon County Utilities Department maintain many existing drainage canals and work with private ditch owners to maintain those private ditches. Lyon County has adopted and updated Strom Drainage regulations but work needs to be done to build the infrastructure to convey water to the Carson River. The discussion on this agenda item is slated to be time specific with Farr West Engineering providing a briefing on the plan for the new Commissioners and then the County Manager and staff presenting the options to the Board.
