SUBJECT: Meeting with Gee & Jenson Personnel on stormwater
Utility Concept
DATE: July 18, 1988
This is to report to you on a meeting Z had this morning with
Ji-ang Song, John McKune and Mike Rocca regarding the concept of a
stormwater utility for the Village of Tequesta.
I explained the primary impetus of our inquiry into the
subject, namely the upcoming expense of the Cypress Drive Drainage
Project, and made them aware of our concerns regarding the equity
and acceptability of such a utility to Village residents and
businesses.
As they explained it, a stormwater utility would be established
according to a stormwater Master Plan by the Village Council, who
would also serve as the utility's governing board. The Master Plan
would define about 4-6 drainage basins in the area to be covered by
the utility. The plan would determine coefficients to measure the
relative uses of the stormwater system. An example of a
coeffecient would be the impervious vs. pervious area for types of
properties; e.g. average $ impervious for residential, $ for retail,
etc. The existing stormwater plan (last updated around 1984) would
serve as the base for the new, more detailed plan.
•
The utility would bill property owners for their fair share of
drainage system operation and maintenance costs as determined by the
study. Capital improvement costs and/or any debt service would
also be billed, again on a fair share basis. The basins would be
defined so that property owners would share in the expense only Por
items directly benefiting their property.
The benefits to the Village potentially realized from a
stormwater utility could include the following:
o Equity to the customers because general ad valorem taxes would
not pay for specific improvements, e.g. Country Club residents
would not pay for any Beach Road drainage improvements and vice-
versa.

-------------------
o Increase the public's understanding of charges for government
services, in that drainage service would be a discrete cost
separate from ad valorem taxes. (NOTE: To arrive at rough
estimate of the annual charge to a Village homeowner, we
divided the approximately 550,000 proposed to be spent on
drainage operation and maintenance in FY 89 by 2500 properties,
which gave a 520.00 annual charge.)
o Provide long-term, reliable financing for stormwater drainage,
which will undoubtedly continue to be critical to the Village.
o Provide relief to ad valorem taxes, especially considering that
government and other property owners not subject to taxes would
be reasonably charged for storn-water services.
o Both the Stormwater Master Plan and the establishment of the
Utility itself would aid in the preparation of the drainage
element of the Village's Comprehensive Plan.
Some conceptual costs of a utility are:
o Initial cost of professional services to design the Stormwater
Master Plan and ongoing costs for any revisions necessary.
o Administrative time, materials required including direction in
development of the Master Plan and ongoing financial services.
(The utility would be an additional enterprise fund, requiring
the associated attention of the Finance Department, the
Auditors, etc.)
o The billing could either be handled through the water billing
process or it could be an annual charge reflected on the tax
bill. Whichever billing vehicle is chosen, once the system was
established, the operating time would be minimal. No
additional personnel should be necessary.
o Legal costs in establishing the utility, which could be
affected by the relative "newness" of the stormwater utility
concept.

o Political disadvantages. Presumably, the business community
would be resistant to any type of cost allocation for drainage,
since commercial property is typically responsible for more
runoff per land area than residential property. A counter
argument would be that equity concerns support property owners
paying for costs associated with and benefits provided to
their property.
If we are interested

Urban Stormwater Manaptmtnt
The basic philosophy of stormwaea
management within urban areas has,
over the past several decades,
changed dramatically. Nationwide
experience with the eRtc~s of in-
adequatepast practices indicates that
stormwater has not always been well
managed, and has often been taiu-
managed. This experience has led to
a major redirection in the ,a„y ~ni-
munities perceive urban drainage
and attempt to deal with it effectively.
Stormr--ater is a difncuh rrsouvre to
manage Primarily because drainage
systems are constantly in a state of
flux. Even a natural drainage system
in its undeveloped condition isnot sta-
tic: streams meander. banks erode,
Wces ue filled b3 sediment. Urbana.
sation compounds this problem.
Urban devebpment requires an al.
together new drainage system to
achieve two basic goals: I) conveni•
ence, and 2) safety. However. local
governments have begun b realise
these two goals are not mutually
achievable without excessively high
costs. Effective stormwater manage-
ment must strike a balance between
the elirniriation of inconvenience as-
sociated with stormwater ruxioff and
the protection of life and property
against food hasard.
Success in stormwater manage.
meat has been elusive. Public works
strategies tried and pro~•en in dealing
with other municipal problems have
not alv-•ays adapted well to drainage
applications. Local governments
have had to develop creative new al.
ternatives for meeting the storniv-•ater
challenge.
The process of developing these a6
ternatives has been slow for several
reasons. First of all, the importance of
storm drainagr u usually apparent
only during floods. Thr public.
through itc elected officials, seldom
placrs storm drainr+Rr high on thr last
of pra-ritirs during annual budget
Proce•~st s. Particularly in thr aril
wrut, th~• thundarstut-att. of spring arr
all bw forgotten during ehe auttunn
scramble !or funds, Second, ~ con-
cept d acomprehensive stormwater
utility with permanent, continuous
financing has only recent)y gained
recognition as an egta;table and de-
pendable approach to stormwater
management. Third, technical ad-
~~ vances in data collection and handling
to facilitate large scale drainage plan-
ning have been avaaiable for little
more than a decade. And finally the
continuing evolution of drainage Lw,
design practices, and environmental
g considerations has forced tics! go~-
ernnients and drainage engineers to
constantly re-evaluate and redirect
their stormwater management
policies.
~ ~ Past it was a generally ac-
ceptable drainage practice to providr
!or the removal of storm ~~ from a
properly a: quickly and econon»cally
as possible. Devebpment of the entire
reach of nattira) drainageways has
made it clear that such a policy can
have disastrous effects on down-
stream properties. To mitigate these
effec4, detention tstylities were re-
quired within new developments to
reduce the rate of runoff into tsatural
ten»~~Sene~ yl benefia'a1, cx-
peraence has shown that the positive
effects of such detention can be
maxinsatted only when devebped in
coNunetion with basin-wade drainage
Planning. It was clew that the ap-
pr+oaeh to storm drainage in the future
~-ould Gave to be aimed at sound
overall management rather than
hasty disposal.
Numerous elements must be con-
sidered in an effective stormwater
management effort, including basin
master planning, fbodp4an adrriinut•
ration, capital improvements pro-
graatiniang, financing, maintenance,
and public relations. To integrate
these auo a successful stormwater
program represents an unprece-
dented challenge for many local gov-
ernments.
Fora Collins u not unique in its at•
tempt to understand storm drainage
and develop a comprehensive
strategy to manage it effectively. Fort
Collins' approach is a synthesis of
concepts and ideas drawn from many
di!'ferent sources. Although informs,
lion above various aspects of urban
storm drainage in other areas u avail-
able, them arr few descriptions of
complete, in-place stormwater man-`
agement systems. The purpose of this
article is to provide such a descrip-

number of proptrtie: b be developed
in the future. In the case of storm
drainage, these plant investment fees
are called ''basin fees." The fees art
based on the weighted area corscept
developed earlier, so that the fee !or a
Particular structure depends on the
lot area, the land use, the on-site de-
tention provided, and the basin is
whicb the structure is located.
Basin fees became tffeetive in Fort
Collins in January 1982. The base rate
for the tees, which do not reflect the
weighting facbrs for runoR coeffr
cients and detention, range from
52,900 b =1,700 per acre. Taking the
w faCbrZ; irlt0 aCt:OUnt, tih!
average bean fits rang! from 51,00
b 52,000 per acre. This means the
new homeowner can expect to PAY
from 5200 b =500 for maijor storm
drainage facilities in the cost d his
house. These basin fees will be re-
viewed and adjusted Periodically b
account tor" changes in construction
costs and the effects of inflation.
Siaoe the basin fees have been io
