How was the flood stage developed?	Computer Model A HEC-RAS Model was made using LiDAR, survey data and some as-built plans. Flows were estimated using USGS StreamStats.
Certainty of flood stage accuracy?	We have 80% confidence in the model results. The survey data reflected differences in the channel bottom since the date the LiDAR was flown in approximately 2008. We did not survey every bridge. To be fully confident in the model we would need to survey the entire creek reach.    LiDAR stands for Light Detection and Ranging. It's a technology that uses laser light to measure distances.
Future Efforts	The FC District may send postcard information to properties along the creek. This could include information on how they can help fine-tune the flood stage by reporting where and when flooding is experienced.
