Lyon County Improvement Surety, Right-of-Way Bonds and Industrial Projects

Lyon County Community Development's application checklist descriptions, revised April 13, 2026, require an improvements surety approved by the District Attorney or a cash deposit to cover 150 percent of the engineer's estimated value of the work. The surety is submitted with the application and approved by the County Engineer before work begins. The checklist also asks for a cost estimate stamped by a Nevada professional engineer, or the executed contractor contract showing the contractor's license number and limit.

Two other checklist items shape the estimate behind the bond. A traffic impact study is required at 500 or more average daily trips or 80 peak-hour trips, and drainage must follow the County's Storm Drainage Guidelines dated September 20, 2024. Off-site road and drainage work that comes out of those studies adds to the engineer's estimate, and at 150 percent every added dollar of work adds a dollar and a half of security.

District Attorney approval means the bond form itself is looked at, not only the amount. A surety should see the County's form early, because nonstandard wording can slow approval and push back the start of work.

A draft ordinance amending Title 15, marked "Revised 09/05/2019" with a blank bill and ordinance number, describes the practice: improvement surety at 150 percent, reducible for completed major components, held one year after the certificate of completion and then replaced by a maintenance bond of 10 percent of the construction estimate, held one more year and released by the Board. The same draft ties final maps to 150 percent surety plus an executed improvement agreement or a certificate of completion.

A March 2, 2023, Board of County Commissioners agenda shows that practice in use. For Traditions Village 1 roadway work, the item released the improvement bond and replaced it with a 10 percent maintenance and warranty bond for the finished portion of the backbone roadway network, and accepted a reduced improvement bond, paid as a cashier's check, for the unfinished part.

Whether the 2019 draft was adopted as written could not be confirmed. Developers should treat the 10 percent, one-year maintenance bond as practice shown in those two documents and confirm the adopted code with the County before budgeting the warranty period.

Lyon County's encroachment permit page says a permit is required for any person, contractor or public utility performing any type of work in the County right-of-way. The Road Division's right-of-way use permit application is undated, and its references suggest an older form, so confirm it is current before relying on it.

For road cuts and excavations, that form asks for comprehensive general liability insurance with limits of at least $500,000/$1,000,000 and a refundable cash bond equal to the engineer's estimate or a licensed contractor's bid, plus 10 percent. It also asks for state and county licenses, inspections by a licensed engineer at the contractor's expense and soils lab testing results before the Road Division's inspection and release of the bond.

Because the bond is cash, not surety, it ties up working capital for the life of the permit and until the soils results clear. A utility or paving contractor with several open cuts can have a meaningful amount held at once, which is worth planning in the bid.

• Cash bond: engineer's estimate or licensed contractor's bid, plus 10 percent
• General liability: at least $500,000/$1,000,000 for road cuts and excavations
• Release: after soils lab results and Road Division inspection
• Form date: undated, so confirm the current version

The master plan describes the Northern Nevada Industrial Center, rezoned in 2020, as about 12,000 acres with about 6,000 developable, and projects over 23 million square feet of industrial space at full buildout on a 20- to 30-year schedule. Silver Springs and Stagecoach sit about a half-hour commute from USA Parkway in Storey County, and the plan notes that a large playa south of the highway at Stagecoach is subject to frequent flooding.

On April 8, 2025, the Planning Commission voted 7-0 to recommend a development agreement with TRACT Capital Management for the Silver Springs Technology Park, covering data centers, high-voltage lines, substations and utility and road improvements on about 460 acres within about 1,070 acres zoned Service Industrial. The agreement takes effect at the closing of the land sale, has no automatic extensions and calls for status updates every two years. In June 2025 the Board began forming the North Lyon County Power District, a general improvement district intended to supply interim microgrid power until the area ties into NV Energy; adoption of the agreement by ordinance was on that agenda, and the final vote is not confirmed here.

The County's development applications page lists 16 items under review, including the Monarch Data Center tentative planned unit development in Mason Valley, an NNIC planned unit development amendment and development agreement revision set for the Board on December 17, 2026, a Greenlink Nevada transmission application and the Legacy 49 tentative map in Dayton. Data center and substation work at that scale typically brings owner-set bonding, builders risk with high values at risk and pollution and utility exposures that can vary by carrier guidelines and programs.
