Douglas County planning commissioners recommend adoption of 2025 Carson River floodplain plan

The Douglas County Planning Commission voted unanimously to recommend that the Board of County Commissioners adopt the 2025 update to the Carson River Floodplain Management Plan, following a presentation from Carson Water Subconservancy District staff and questions from commissioners.

Courtney Walker, stormwater program manager for Douglas County, introduced the Carson Water Subconservancy District presenters and described the county's relationship with the regional plan. "We've coordinated quite a few projects together," Walker said, noting that CWSD acts as a FEMA cooperating technical partner and that the plan helps counties secure FEMA funding and participate in the Community Rating System that can reduce flood insurance premiums.

The plan, originally prepared in 2008 and updated periodically, presents a watershed-scale approach to reduce flood risk across Alpine, Storey, Douglas, Carson City, Lyon and Churchill counties. Debbie (Carson Water Subconservancy District staff) and Brenda Hunt, CWSD watershed program manager, described the plan's goals, the guiding "Living River" approach and the document's structure, which groups mitigation into eight strategy categories and lists 49 suggested actions for counties and partners to implement.

"The more we think about water before it floods, the better prepared we can be when it floods," Debbie said, summarizing the plan's emphasis on planning and mitigation. Presenters said the plan aims to protect floodplain function and land uses that aid groundwater recharge and flood attenuation, such as agricultural fields and open-space corridors.

Commissioners asked how the plan's recommendations relate to local regulations and projects. Walker said the county uses area drainage master plans and a separate stormwater master plan for site-level and implementation details, and noted that the CWSD plan is higher-level and watershed-wide. She said some issues that matter locally'for example, smaller unmapped flooding events or irrigation-ditch maintenance'are addressed in county plans or will be handled through the county's stormwater master plan.

Commissioners and staff discussed several implementation topics raised in the presentation: incentivizing floodplain conservation through leases or conservation easements, the role of transfer-of-development-rights programs in protecting floodplain sending areas, the need to coordinate emergency management and local implementation to overcome barriers, and the importance of audit and update work on stormwater ordinances. Brenda Hunt noted CWSD's recent audits of county stormwater ordinances and suggested ordinance changes to better fit the local dry-climate context.

A public comment from John Coburn, a resident and retired University of Nevada Cooperative Extension employee, urged support for the plan and noted long-term stakeholder involvement in the Carson River Coalition. "Douglas County has been very active at pursuing the goal of better floodplain management," Coburn said.

Planning Commissioner Kirk moved the commission's recommendation that the Board of County Commissioners adopt the 2025 update to the Carson River Floodplain Management Plan; Commissioner Dan seconded the motion. The commission voted in favor; the motion passed unanimously.

The presenters and county staff noted that appendices and detailed county progress reports were not included in the packet before the commission but are available through CWSD's website; Walker said she would share a link. Commissioners were also reminded that Douglas County's stormwater master plan will be discussed at a special Board of County Commissioners meeting on Sept. 17 at 3 p.m., where county-specific projects and capital improvements will be presented.

The commission's recommendation will be forwarded to the Douglas County Board of County Commissioners for consideration.
