When it rains in Lincoln, stormwater flows into drainage inlets, gutters and underground pipes before reaching Salt Creek, which drains into the Platte River. Lincoln occasionally gets more rain than the storm drain system or streams can adequately convey, which can lead to flooding.
A floodplain is an area of land that is susceptible to flooding or that has flood prone soils. Approximately 13.8% of Lancaster County is covered by floodplains. Floodplains provide multiple benefits to both the natural (flood storage, habitat, water quality) and built (recreation, public health and safety, economic) environments. The overriding development policy for the floodplain is a "No Adverse Impact" policy for the City and County, which means that the community has a goal of insuring that the action of one property owner does not adversely impact the flooding risk for other properties.
The Lincoln Watershed Management division, in partnership with the Federal Emergency Management Agency (FEMA) is working to update Lincoln and Lancaster County flood maps. This years-long effort will offer up-to-date flood management data that will assist in mitigating area flood risks.
If you live in a floodplain, create and practice an emergency plan so your family will know what to do during a flood. Remember to plan for everyone in your home, including pets.

The Community Rating System (CRS) is a voluntary program developed by the Federal Emergency Management Agency (FEMA) to rate communities on how effectively they manage their floodplains. Local governments participating in the CRS go beyond the minimum standards for floodplain management. The City of Lincoln has been actively involved with FEMA’s CRS Program since October 1991.
The goals of this study were to evaluate the potential impact that proposed offline storage would have on flood depths along Salt Creek and to evaluate the storage benefit of Wilderness Park under existing conditions using the Salt Creek DFIRM update model.
In August of 2001, former Mayor Wesely appointed the Mayor's Floodplain Task Force, representing a range of stakeholders from the community, to formulate recommendations regarding the development of new floodplain standards.

These documents explain the unique methods for modeling the Salt Creek floodplain.
This agreement between the Salt-Wahoo Watershed District (now NRD) and the City of Lincoln authorized the local management of storm drainage and flood control.
The Flood Mitigation Master Plan will assess risk and identify actions that can reduce long term flood risk to human life, local properties, and the environment.
The goal of this project is to reduce adverse impacts from flooding to life and property from existing and future flood events.
