Michael,
Per your request, we have evaluated the use of a retaining wall for the purposes of floodplain reclamation on
the property situated at the northeast corner of Freeport Parkway and Cottonwood Branch.
After further analysis, our recommendation would be to construct a retaining wall along the same horizontal
limits of fill previously shown. This is due to the fact that filling beyond this point would effectively block the
proposed bridge opening.
However, the analysis also indicates that if a retaining wall were to be constructed, there would no longer be
a necessity for additional channel grading below the reclamation limits. Furthermore, the proposed wall
does not adversely impact water surface elevations along the channel, or the proposed bridge design.
I have attached a revised exhibit which depicts both reclamation options. Please don’t hesitate to contact
Mark Holliday or myself if you have any questions.
Regards,
Niraj
