In response to your letter dated April 5, 1994, and as a follow-up to Mr. Dan Eckis's letter of
April 12, 1994, we have the following response:
Northeast Retention Area -
The city will remove the four (4) inch PVC pipe located in the west berm connecting the
retention area to the Rosebush Lane swale.
The retention areas of the Barber Street Sports Complex were designed and permitted
in accordance with the rules and regulations of the St. John's River Water Management
District. It is apparent that a recovery problem does exist and the existing subsurface
conditions are not performing as predicted by the soils testing firm for this project.
The ideal corrective action to solve the problem would be to deepen the retention areas
and turn them into lakes, but this is not an acceptable alternative to the City due to
the liability of the lakes. We are open to suggestion from the Water Management
District as to acceptable corrective action.
Northwest Retention Area:
The permit modification, 42-061-065NG, permitted this grassed overflow swale.
2. Refer to item 2 above.
The permit modification 42-061-065NG permitted the removal of the Type "C" inlet
15 inch C.A.P. and the trench drain.

With regard to the pipe between the east and west retention areas, this pipe is strictly an
equalization pipe. The site drainage is basically equally split between the two retention ponds.
If the District insists that this equalization pipe is essential to the functioning of the stormwater
system, then the City will install the pipe. -
