Projects with Flood Control and Drainage Systems
The Truckee Meadows Stormwater Quality Management Program, a joint effort between Reno, Sparks, and Washoe County, has a wealth of information including Design Manuals, Structural Controls Guidance Manuals, Truckee River Watershed Map tools, the Truckee River Info Gateway (TRIG), and a Watershed MapServer.
The 2009 Truckee Meadows Regional Drainage Manual and accompanying Errata is used by City of Reno, City of Sparks, and Washoe County to ensure consistency in analysis, planning, and design of projects with flood control and drainage components.

Development in Special Flood Hazard Areas
The Division also reviews all new development located in special flood hazard areas (FEMA Flood Zones). All development in the flood zones are controlled by Washoe County's Ordinance No. 416 (flood regulations), and Federal Emergency Management Agency (FEMA) regulations. Flood Insurance Rate Maps are the official community maps on which FEMA has delineated both the special hazard areas and the risk premium zones applicable to a community. The CSD Engineering & Capital Projects Division is the repository for the Flood Insurance Rate Maps for Washoe County.
The National Flood Insurance Program (NFIP) webpage provides information on the program to a variety of audiences including surveyors.
The NFIP Elevation Certificate is an administrative tool used to provide elevation information necessary to ensure compliance with community floodplain management ordinances, to determine the proper insurance premium rate, or support a request for a Letter of Map Amendment.
