Subject: Woodridge Channel - Tailwater Sensitivity Analysis
Ken and Michael,
I hope this email finds you well!
Please find attached a letter and exhibits summarizing the results of a tailwater sensitivity analysis performed by TNP for the Woodridge Channel. To summarize, TNP evaluated the impacts
of four different tailwater boundary conditions at the confluence of Woodridge and Denton Creek:
1. Normal depth,
2. Tailwater based on coincidental peaking,
3. Tailwater based on the 100-year FEMA BFE,
4. Tailwater based on field observations by City staff;
In general, the findings indicate that, for the range of tailwater elevations considered, the impacts largely play out beginning at the downstream face of MacArthur and proceeding upstream.
Please let me know if you have any questions. I am happy to discuss this further at any time.
Best Regards,
niraj
