July 2008
Progress Summary
- Watershed Inventory
- We have completed compiling the bulk of available GIS information from the City, County, NRD and other available sources for use as the base in our data gathering effort.
- Hydrology and Hydraulics
- The watershed hydrology is complete. We evaluated stormwater runoff and stream flows throughout the watershed for the 2- 10-, 50-, 100-, and 500-year storm events. The model was calibrated using existing stream gauge data.
- The hydraulic model is prepared and awaiting hydraulic structure survey data from our team survey crew. Over 70 stream structures (bridges and culverts) were surveyed for use in the model. Once this data is entered, we will begin running the hydraulic model and updating the floodplain maps.
- Water Quality
- The water quality data collection is scheduled to begin in August/September 2008.
- Geomorphology
- The geomorphic field data collection, data reduction and diagnosis of how the streams are changing are complete.
- Soils Assessment
- Soil field sample collection and lab testing is scheduled for completion in July 2008.
- Structures
- Survey control is established for the watershed, and the hydraulic structure survey is scheduled for completion in July 2008.
- Public Involvement and Participation
- The first Technical Advisory Committee (TAC) and Citizen Advisory Committee (CAC) meetings are complete, as is the first open house. The second TAC meeting is scheduled for July 2008 and the second CAC meeting is scheduled for the end of summer/early fall 2008. The first newsletter was mailed in April 2008 and this is the second.
- Deliverables
- The final report appendix section for the aerial photo analysis has been submitted and reviewed. Website data for to-date progress and TAC, CAC, and open house information and notes were submitted and are available on the city website at lincoln.ne.gov (keyword: watershed).
- The draft geomorphology section and draft hydrology section are scheduled for July 2008.
