Proposed Typical Cross Sections and Longitudinal Profile for Proposed Structures
Regional Curve Estimates:
Cheek Creek at the state road (SR 1563) crossing is estimated by USGS StreamStats to be a 9.76 square
mile drainage. Using Regional Curve equations for the proposed channel dimensions are as follows:
a) Bankfull Cross-Sectional Area: 100.9 feet'
b) Bankfull Discharge: 459.2 cfs
c) Bankfull Width: 31.7 feet
d) Bankfull Mean Depth: 3.1 feet
