To: Stormwater Utility Board DICTATED BUT NOT READ TO ‘(*)9
From: Thomas G. Bradford, Village Manager EXPEDITE. K !-b
Date: 05/22/1996
Subject: Stormwater Utility Capital Projections; Agenda Item
At your first Stormwater Utility Board Meeting, it was requested
that a listing, explanation and cost estimate for each of the
outstanding known Stormwater Capital Projects be reviewed and
presented at your next Board Meeting. On May 20 , the Public
Works Committee reviewed the attached Stormwater Utility Capital
Projections Spreadsheet, which prioritizes the stormwater
projects, showing the impact on such projects on a cash basis and
a debt service basis, as well as indicating the revenue sources
to address this expense.
Revenues are derived from capital account balances, General Fund
Undesignated Balance and projected Stormwater Utility Fees .
It is the recommendation of the Public Works Committee that the
Village proceed as follows :
1 . For revenues , draw down all account balances as indicated in
the attached spreadsheet, including the use of $175, 000 of
the General Fund Undesignated Fund Balance .
2 . For project expenditures, proceed on a cash basis, as
indicated in the attached spreadsheet .
3 . Proceed now with the Dover Ditch Maintenance Dredge Project,
Tequesta Drive Drainage Diversion Project and the Seabrook
Road North Project, totaling an estimated $319 , 000, with
funding as indicated in the attached revenue spreadsheet for
FY 96 .
Proceeding in this fashion will require the Village General Fund
to subsidize the Stormwater Utility capital needs over the next
five fiscal years , to the tune of $121 , 500 . This would be in
addition to any "seed money" provided to the Utility, if any.
The cash basis proposal is desirable in that it allows the
Village greater flexibility in adjusting the scope of the
projects and the timing of the projects, depending upon
circumstances which may arise over which the Village has very
little control .
Page 2-
Please note that, in addition to all of the revenues listed,
there is the possibility of an additional estimated $60, 000 from
FEMA, which represents funds in excess of expenditures for
October storm damages, and a separate FEMA application for
$70, 000 to mitigate future Dover Ditch area flooding by diverting
Tequesta Drive drainage westward to discharge at the Tequesta
Drive Bridge. If we are successful in securing these funds, this
will be an additional $130, 000 that can either be returned to the
General Fund to off-set its proposed contribution to these
drainage projects, used as the funds for the future subsidy of
the Stormwater Utility Capital Projects, or to expedite the
completion of projects projected in the out years .
Finally, the Director of Finance has been on vacation in the last
week or so and, as of this writing, has not commented on the
acceptability of the revenue sources listed in the attached
spreadsheet. Please seek Mr. Kascavelis ' approval of the same
prior to proceeding in any direction.
In the event that you wish to discuss the same, I have also
enclosed a project description provided by Gee & Jenson and the
two Amortization Schedules that were submitted to the Public
Works Committee for their review.

During the final five (5) months of fiscal year 1996, the Public Works Department will
continue to inspect and maintain the drainage system on a regular schedule. Before
and after all major storms, the complete exterior of the drainage system will be
inspected and appropriate maintenance action will be performed. With the exception
of the drainage items discussed at the Public Works Committee Meeting on May 20,
1996, no additional major drainage repairs or improvements are anticipated.
In conclusion, I believe the Stormwater Utility Board would appreciate knowing that
residents are often confused about water standing in the drainage pipes for a long
period of time. Residents believe that standing water in the pipe system simply means
the system is filled with debris and is not properly functioning. There are several
reasons why water sometimes remains in the inlet structures.
1 ) In one (1 ) location in the Tequesta Country Club Community, over one hundred
(100) acres and twenty (20) inlet structures use only one (1 ) outfall. During
heavy rain such as the October 1995 flood, the stormwater may remain in or
over the inlet structures for hours or days before discharging.
2) The Village drainage system has eighteen (18) French Drains. French Drains do
not have positive outfalls and whenever the water table is high, water wiH stand
in these drains.
3) At the South Gate of the Country Club Community, the drainage system that
starts on Country Club Drive and crosses Yacht Club Place, Fairview East and
Fairview West and ends at Retention Pond No. 12, has standing water in the
pipe system at all times. Due to the elevation in this area, the retention pond
is actually higher than the bottom of the inlet structure. The system works only
when the inlet structure is near stormwater capacity.
4) Due to the condition of Dover Ditch and the tidal changes in this area, most of
the inlet structures have some standing water at all times.
