We are not talking about the property to the westwe are talking about the property between our north entrance
and the bank on the corner of Denton Tap and 121 on the north side of Natches Trace to.

I have reviewed the drainage design for Magnolia Park and have the following observations to
offer:
1) The west side of Magnolia Park appears to be the high point in the drainage area. This
means that Magnolia Park's drainage flows east to the channel and the property to the west
drains west and south, away from Magnolia Park;
2) Neither the Magnolia Park channel nor the culverts beneath Waverly Lane or Levee Place
were designed to accept water from the west of Magnolia Park.
If the property to the west still desires to pursue discharging their drainage to the east and into
Magnolia Park, they would need to hire an engineer that specializes in hydraulics and
hydrology to perform a detailed analysis of the entire drainage basin and system to determine
if the existing drainage system and culverts have the capacity to accept rerouted water from
the west. The analysis should also evaluate the impacts of the rerouted water to ensure that
there are no adverse impacts to the existing houses that may lead to potential flooding in the
future.
Without the analysis, the only decision that the city can offer in this matter is that the water
can not be rerouted to the Magnolia Park drainage system.
If you have other questions or need additional information, please contact me at your
convenience.
