RESOLUTION NO. 13-2004
A RESOLUTION OF THE TOWN COUNCIL OF THE
TOWN OF TmURON ESTABLISHING A
STORMWATER RUNOFF IMPACT FEE
WHEREAS, impervious surfaces within the Town ofTiburon have a direct impact on
the magnitude of stormwater flows; and
WHEREAS, the creation of additional impervious surfaces due to construction
activities further increases stormwater runoff and reduces the capacity, performance and
sustainability of the Town's storm drain system; and
WHEREAS, it is appropriate for construction projects resuhing in new impervious
surfaces to pay an impact fee to offset the increased demand on the capacity, operation, and
sustainability ofthe storm drain system; and
,.-..
WHEREAS, the Town ofTiburon has adopted an ordinance (codified as Chapter 14B
of the Municipal Code) establishing the authority for imposing and collecting Public Facilities
Development Fees; and
WHEREAS, the Town has provided public notice of the proposed impact fee in
accordance with Government Code, ~~66000 et seq.; and
WHEREAS, the Town Council further finds as follows:
A. The purpose of the stormwater impact fee is to upgrade, enhance, and/or
rehabilitate the Town's storm drain system to accommodate drainage water
resulting from the creation of new impervious surfuces.
B. The stormwater generated through creation of new impervious surfaces over
the corning years may likely exceed the capacity of the Town's current storm
drain system in the absence of substantial improvements and will hasten the
deterioration of existing storm drain fucilities. There is a substantial
government interest in maintaining an adequate storm drain system in order to
prevent flooding and other damage to public and private property.
C.
The Town has conducted studies and analyses regarding the extent of its
storm drain system and the estimated cost of its future rehabilitation. The
Town's future storm drainage rehabilitation costs are estimated at
$12,210,100 in the GASB 34 Infrastructure Valuation Study (hereafter

"GASB Analysis"), prepared by the engineering firm of Harris & Associates,
dated March 3, 2004, and available for review in the Office of the Town
Engineer. The Town Engineer also prepared the Town ofTiburon Drainage
Impact Fee Analysis (hereafter "Fee Analysis"), revised March 29, 2004,
available for review in the office of Town Engineer, which estimates an
impervious surface total for the Town of 12.17 million square feet that
contributes to stormwater runoff. This means that the proportionate unit cost
to rehabilitate the storm drain system is approximately $1.00 per square foot
of impervious surface.
D.
In the judgment of the Town Engineer, the current storm drain system will not
be. sufficient to accommodate the amount of runoff likely to be generated by
new impervious surfaces in the foreseeable future. Without significant
drainage improvements, the Town's storm drain system will likely deteriorate
to a point where flooding and property damage would occur.
E.
The Town Council finds that because the Town ofTiburon is approximately
95% built out, traditional stormwater improvements instaIled by new
subdivisions will not meaningfully reduce the Town's cost for storm drain
system improvements. The Town therefore seeks to require all new
impervious surface creation to contribute its pro rata share to the cost of
upgrading and rehabilitating the Town's storm drain system.
-
F. The Town Council finds, based on the Fee Analysis, that there is a reasonable
relationship between the need for the improvements to be funded by the fee
and the type of development project upon which the fee is imposed.
SpecificaIly, every project on which the fee is imposed generates increased
stormwater runoff by replacing pervious surfaces with impervious surfaces.
This generation of additional runoff requires that, in order to achieve and
sustain an acceptable condition and capacity within the Town's storm drain
system, drainage improvements must be made to the existing system in order
to accommodate the increased storm water runoff. There is a reasonable and
direct connection between the need for the improvements and the type of
development project upon which the fee is imposed.
G. The Town Council finds that there is a reasonable relationship between the
fee's use and the type of development for which the fee is charged. The fee
will be used exclusively to upgrade and rehabilitate storm drain system
components (including but not limited to pipes, culverts, inlets, and catch
basins); and will be used for the engineering, planning and administrative costs
directly related to such components. The use of the funds will therefore
directly relate to and benefit the construction projects upon which the fee is
imposed; and

H. The Town Council finds that there is a reasonable relationship between the
amount of the fee and the cost of the projected required improvements. The
cost of rehabilitating the storm drain system has been determined using
standard engineering practices at $12,210,100 in 2003 dollars in the GASBY
Analysis. Approximately 12.17 million square feet of residential impervious
surface area contributes to the Town's existing storm drain system. This
creates a ratio of$I.00 for each square foot of impervious surface toward the
upgrade and rehabilitation of the storm drain system. Thus, a fee of$I.00 per
square foot of new in3pervious surfuce in construction projects is roughly
proportional to that project's contribution to increased storm water runoff.
1.
The Town Council finds, based upon the judgment of the Town Engineer and
as set forth in the Staff Report dated Apri17, 2004, that aging, deteriorating,
undersized, or otherwise problematic components of the Town's storm drain
system are dispersed throughout the Town limits such that virtually all new
impervious surfaces will impact one or more of these problematic components
of the Town's storm drain system. Therefore, for purposes of establishing a
zone of benefit for storm drain system rehabilitation, it is logical and
reasonable to designate the entire Town ofTiburon corporate limits as a single
benefit zone. New impervious surface will be assessed fees based upon a
single fee established for the entire zone of benefit.
