Box 9960 College Station, TX 77840 MITCHELL MM MORGAN RE: Detention Certification for Ramada Hotel Dear Josh: December 10, 2008 I have conducted a topographic review and field investigation of the existing and proposed flow patterns for stormwater runoff from the Ramada Hotel project to Burton Creek. At build-out conditions allowable by zoning, restrictive covenant, or plat note, the stormwater flows from the subject subdivision or site project will not cause any increase in flooding. The ultimate development of the Ramada Hotel development will not increase the peak discharge at Burton Creek and SH 6. Furthermore, the development has no impact on the timing of the peak the location. Due to th is, the ultimate development of the Ramada Hotel development and releasing its runoff undetained will not have an adverse effect on the streams to which this development discharges. If you have any comments, or would like to discuss our findings further, please feel free to contact me.

Box 9960 College Station, TX 77840 MITCHELL M M MORGAN RE: Detention Certification for Ramada Hotel Dear Erika: January 28, 2009 I have conducted a topographic review and field investigation of the existing and proposed flow patterns for stormwater runoff from the Ramada Hotel project to Burton Creek. At build-out conditions allowable by zoning, restrictive covenant, or plat note, the stormwater flows from the subject subdivision or site project will not cause any increase in flooding conditions to the interior of existing building structures including basement areas for storms of magnitude up thru the 100 year event. The ultimate development of the Ramada Hotel development will not increase the peak discharge at Burton Creek and SH 6. Furthermore, the development has no impact on the timing of the peak the location. Due to this, the ultimate development of the Ramada Hotel development and releasing its runoff undetained will not have an adverse effect on the streams to which this development discharges.
