Ordinance No. 2026-05 Page 3 of 10
which fees shall be tiered to take into account the intensity of development proposed for
the property. The fee tiers shall be as follows: low-density residential; medium-density
residential; high-density residential; and commercial/industrial. The drainage fees for
each drainage shed shall be imposed on a pro rata, per acre basis upon any parcel or
other piece of property for which an owner, developer or other applicant has requested
approval to develop or redevelop, or to construct or reconstruct any structure upon such
property pursuant to Chapter 15-70, prior to, and as a condition of approval being granted
for such development or construction.
§ 15-66 Storm Drainage Watershed Funds
The funds collected hereunder shall be deposited in two separate funds which shall be
known as the "Santa Ana Watershed Drainage Fund" and the “Newport Bay Watershed
Drainage Fund”. In the case of land development subject to the Subdivision Map Act, the
drainage fee for the appropriate watershed, as defined in the adopted Storm Drain
System Master Plan and its Storm Drainage Impact Fee Nexus Study, shall be collected,
deposited and expended in accordance with Section 66483 through 66483.2 of the
California Government Code, in addition to the provisions set forth below, and all other
applicable laws of the state. In the case of any development, redevelopment,
construction, or reconstruction not subject to the Subdivision Map Act, the drainage fee
for the appropriate watershed shall be collected, deposited and expended in accordance
with Sections 66000 through 66008 of the California Government Code, in addition to
the provisions set forth below, and all other applicable laws of the state.
§ 15-67 Required Construction.
(a) Whenever a development is planned in a location where the Storm Drain System
Master Plan or condition of approval calls for a storm drain and the applicant or developer
is required to construct the storm drain upon a public right-of-way or on private property
to be dedicated as a public right-of-way, the applicant or developer shall be required to
post appropriate bonds to cover the estimated construction cost of the storm drain and
submit copies of bid prices to the City Engineer prior to construction. Any and all such
bonds shall be exonerated upon acceptance of construction by the City Engineer.

Ordinance No. 2026-05 Page 4 of 10
(b) If the City Engineer determines that additional drainage facilities are required in order
to adequately provide for drainage, the City Engineer may require, as a condition of
approval, the construction of those facilities for the detention of stormwater or such other
means as may be necessary to provide adequate drainage of a particular property without
adversely affecting adjacent properties or the City's drainage system.
(c) Notwithstanding anything provided in this Section 15-67 or elsewhere in this Chapter
III, any construction of drainage facilities required to be constructed prior to issuance of
development approval shall be in addition to, and not in lieu of, imposition of the drainage
fee applicable to that property. Facilities included in the Storm Drain System Master Plan
may be eligible for credit and/or reimbursement pursuant to this chapter.
§ 15-68 Fee refund.
If a building permit expires without commencement of construction or a subdivision or
parcel map is abandoned prior to final approval, then the applicant or developer shall be
entitled to a refund, without interest, of the impact fee paid as a condition for its issuance,
except that the City may retain the actual administrative costs incurred on behalf of said
applicant or developer, in accordance with Section 66014 of the California Government
Code. The fee payer must submit a written request for a refund to the City Engineer within
30 calendar days of the expiration of the permit. Failure to submit the required application
for refund in a timely manner shall constitute a waiver of any right to the refund.
§ 15-69 Use of funds.
The money obtained through payment of drainage fees as provided for in this chapter
may be used by the City to defray the cost of constructing storm drains and related
facilities as identified in the Storm Drain System Master Plan. The City may incur
indebtedness for the construction of any drainage facility and utilize either of the drainage
fee funds for repayment.
§ 15-70 Fees to connect to existing facilities.
Subject to the provisions of Section 66013 of the California Government Code,

§ 15-71 Applicability of fees.
Drainage fees shall be imposed in the following cases:
(a) For low density residential uses, any improvement, addition or major alteration to an
existing structure or construction of an accessory structure, in any form, where the
aggregate gross impervious percentage of the parcel as a result of such improvement
exceeds 50% of the gross acreage of the parcel is subject to a drainage fee for the
exceeding impervious acreage. The applicable drainage fee shall be calculated pursuant
to the following formula:
Fee = (Impervious area exceeding 50% of the gross parcel acreage) X (Fee per
Impervious Acre)
(b) For medium density residential uses, any improvement, addition or major alteration to
an existing structure or construction of an accessory structure, in any form, where the
aggregate gross impervious percentage of the parcel as a result of such improvement
exceeds 70% of the gross acreage of the parcel is subject to a drainage fee for the
exceeding impervious acreage. The applicable drainage fee shall be calculated pursuant
to the following formula.
Fee = (Impervious area exceeding 70% of the gross parcel acreage) X (Fee per
Impervious Acre)
(c) For high density residential uses, any improvement, addition or major alteration to an
existing structure or construction of an accessory structure, in any form, where the
aggregate gross impervious percentage of the parcel as a result of such improvement
exceeds 80% of the gross acreage of the parcel is subject to a drainage fee for the
exceeding impervious acreage. The applicable drainage fee shall be calculated pursuant
to the following formula.
Fee = (Impervious area exceeding 80% of the gross parcel acreage) X (Fee per
Impervious Acre)
(d) For commercial and industrial uses, any improvement, addition or major alteration to
an existing structure or construction of an accessory structure, in any form, where the
aggregate gross impervious percentage of the parcel as a result of such improvement
exceeds 90% of the gross acreage of the parcel is subject to a drainage fee for the
ATTACHMENT 1
Ordinance No. 2026-05 Page 6 of 10
exceeding impervious acreage. The applicable drainage fee shall be calculated pursuant
to the following formula.
Fee = (Impervious area exceeding 90% of the gross parcel acreage) X (Fee per
Impervious Acre)
(e) For development of vacant land, any improvement or construction is subject to a
drainage fee. The applicable drainage fee shall be calculated pursuant to the following
formula.
Fee = (Gross Parcel Acreage) X (Land Use Impervious Factor) X (Fee per Impervious
Acre)
(f) For land use changes, where the impervious factor for the future land uses as identified
in the Storm Drain System Master Plan is greater than the impervious factor of the existing
land use as identified in the Storm Drain System Master Plan.
Fee = (Drainage Fee per Acre of Future Land Use – Drainage Fee per Acre of Existing
Land Use) X (Gross Property Acreage)
Drainage fees shall not be imposed in the following cases:
(a) For accessory dwelling units (ADU) less than 750 square feet.
(b) For reconstruction of existing structures in the event of a disaster where the
reconstruction does not increase the impervious area of the parcel.

identified in the Storm Drain System Master Plan is less than the impervious coefficient
of the existing land use.
§ 15-72 Deposit of fees.
Subject to the provisions of the Subdivision Map Act or Sections 66000 through 66007 of
the California Government Code, as applicable, a drainage fee paid in accordance with

A. Whenever the conditions of approval of a development project require direct
construction of a public storm drainage facility (see Section 15-67) described or
listed in the Storm Drain System Master Plan, a credit or reimbursement, as
applicable, shall be given against the development impact fee, which would have
been charged to the development project under the program, for actual
construction costs incurred by the developer, up to the cost included in the Storm
Drain System Master Plan. The reimbursement and/or credit amount shall not
include any improvements the City can require from the development project under
the Subdivision Map Act, or the portion of the improvement deemed to be an on-
site improvement that is not included in the Storm Drain System Master Plan.

§ 15-75 Appeals
A. A developer subject to the drainage fees required by this chapter for a particular
project may apply to the City Council for: (a) a fee adjustment based upon a
showing of substantial evidence of a lesser impact upon the level of service; or (b)
a land use category adjustment based upon a showing of substantial evidence that
another land use category is more appropriate for a particular development.; or (c)
a fee adjustment based upon a substantial showing of evidence of increased site
permeability, including but not limited to permeable surfaces, bioswales, or other
stormwater infiltration features, that will reduce stormwater runoff and impacts to
the City’s existing drainage system. Any fee adjustment proposed pursuant to
subsection (c) shall be subject to final review and approval by the Public Works
Director. The written appeal and the applicable appeal fee must be filed with the
City Clerk’s Office prior to the issuance of building permit. The City Council shall
establish the appeal fee by resolution. The appeal shall state in detail the factual
basis for the request for adjustment.

and (A)(b) at a public meeting to be held within 60 calendar days after the appeal
application has been filed. Appeals submitted pursuant to subsection (A)(c) shall
be reviewed by the Public Works Director, and such review shall be completed
within 60 calendar days after the appeal application has been filed. The decision
of the City Council or Public Works Director, as applicable, shall be final. The
decision shall be in writing and shall be mailed to the applicant.
C. If an adjustment is granted pursuant to this section, any subsequent change or
intensification of the use or uses of the property or any expansion of the structures
on the property, or removal or modification of the site permeability or stormwater
infiltration features relied upon for the adjustment, shall invalidate the adjustment,
and the applicant shall be subject to the development impact fee requirement
applicable to the entire development based on the fee in effect at the time of the
change, expansion, removal, or modification, less any amount previously paid.
D. If an adjustment is not granted pursuant to this section, then upon the payment of
the required fees, the City shall provide the applicant a written notice of the amount
