The City of Lincoln (City) and Lower Platte South Natural Resources District (LPSNRD) staff, as well as other planning and design engineers, are developing the Little Salt Creek Watershed Master Plan. The Little Salt Creek Watershed is located north of the City of Lincoln and flows into Salt Creek just southeast of I-80 at 27th Street.
The objective of the study is to develop a master plan that will proactively forecast, evaluate, and manage stormwater quantity and quality, channel stability, maintenance and operations, and financial impacts as well as environmental impacts that are occurring today or are projected to result from future development or other changes in the basin. The master plan will consider potential impacts to unique and sensitive environmental resources in the watershed, including rare saline wetlands, the state endangered saltwort plant (Salicornia rubra) and the Salt Creek Tiger Beetle (Cicindela nevadica lincolniana). This project will also include hydraulic and hydrologic modeling to determine flood prone areas. All information gathered will be provided in a Geographic Information System (GIS) format compatible with the City of Lincoln's GIS database.
The master plan will include:
- A watershed inventory to collect, compile and evaluate existing data about the watershed.
- A geomorphic analysis to determine potential erosion and other stream stability issues along Little Salt Creek and its tributaries.
- Hydrologic and hydraulic models to determine flood prone areas.
- Preliminary identification of Best Management Practices (BMPs) and/or Capital Improvement Projects (CIPs) to address problem areas.
- Prioritization of problem areas based on degree of flooding or erosion, potential impacts to environmental resources, importance of habitat/resource protection, and location relative to the future growth of Lincoln.
- Revising the FEMA Digital Flood Insurance Rate Maps (DFIRMs) for the area downstream of the 14th Street bridge.
- A limited stream bioassessment. Water quality testing to determine potential water quality issues.
- Final identification of BMPs and CIPs to address flooding, erosion and water quality problem areas.
- Formulation of guidelines and recommendations for future development in the watershed.
- Identification of potential funding sources for future studies and/or implementation of BMPs and CIPs, and the creation of the final master plan.
