Re.: As -Built Drainage Letter
Carter's Crossing, Phase 2
MBESI No. 1015-0007
Dear Mrs. Singh:
The purpose of this letter is to provide information to you in regards of the drainage facilities in
Carter's Crossing Phase 2 based on as built conditions. We ran the hydraulic model of the
subdivision with the as built elevations to determine how the box culvert under Appomattox
Drive and the pipe culvert under the sidewalk would perform. The results are as shown below:
Appomattox Drive Culvert
100 Year W.S.E. = 255.76
Top of Road = 256.34
36" Pipe Culvert
100 Year W.S.E.= 254.08
Elevation of Park Boundary = 255.10
The stormwater will remain within the creek without going over Appomattox Drive at the culvert
location. Additionally, the 100 year storm is contained within the park boundary and will not
encroach onto the lots.
If you have any questions, please do not hesitate to contact me.
Sincerely,)
4RoG•l
