Abstract (Summary)

Cajon Creek, near Devore Heights, California, is currently lacking much-needed hydrologic and hydraulic studies. The Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) shows that the 100-year floodplain delineation terminates east of the I-15 freeway. This study will extend the floodplain mapping for Cajon Creek and analyze existing culverts. There are several reasons to complete this project. First, it will aid stakeholders in developing the area adjacent to Cajon Creek. Second, Caltrans plans to improve the I-15/I-215 interchange, which would require additional bridges over Cajon Creek. Third, there have been recurring flooding problems from the tributary washes due to the undersized culverts and sedimentation under the I-15 freeway.

Geographic Information Systems (GIS) was utilized to manage data and incorporate the information needed for the hydrologic model and hydraulic analysis. The results show that the delineated 100-year floodplain for Cajon Creek will potentially experience floods much greater than expected.
