AN ORDINANCE AMENDING TITLE 5 OF THE CITY OF BALDWIN PARK
MUNICIPAL CODE TO ESTABLISH LOW IMPACT DEVELOPMENT STANDARDS
Findings.
(A) The City of Baldwin Park is authorized by Article XI, §5 and §7 of the State Constitution
to exercise the police power of the State by adopting regulations to promote public
health, public safety and general prosperity.
(B) The City of Baldwin Park has authority under the California Water Code to adopt and
enforce ordinances imposing conditions, restrictions and limitations with respect to any
activity which might degrade the quality of waters of the State.
(C) The city is a permittee under the "Waste Discharge Requirements for Municipal Separate
Storm Sewer System (MS4) Discharges within the Coastal Watersheds of Los Angeles
County, Except those Discharges Originating from the City of Long Beach MS4," issued
by the California Regional Water Quality Control Board--Los Angeles Region," (Order
No. R4-2012-0175) which also serves as an NPDES Permit under the Federal Clean
Water Act (NPDES No. CAS004001), as well as Waste Discharge Requirements under
California law (the "Municipal NPDES permit"). In order to participate in a Watershed
Management Program and/or Enhanced Watershed Management Program, the Municipal
NPDES permit requires permittees to develop and implement a LID Ordinance.
(D) The City of Baldwin Park is committed to a stormwater management program that
protects water quality and water supply by employing watershed-based approaches that
balance environmental, social, and economic considerations.
(E) Urbanization has led to increased impervious surface areas resulting in increased water
runoff and less infiltration to groundwater aquifers causing the transport of pollutants to
downstream receiving waters.
(F) LID is widely recognized as a sensible, cost effective approach to managing the quantity
and quality of stormwater runoff by setting standards and practices to maintain or restore
the natural hydrologic character of a development site, reduce off-site runoff, improve
water quality, and provide groundwater recharge.
(G) It is the intent of the City of Baldwin Park to expand the applicability of the existing
Standard Urban Stormwater Mitigation Plan (SUSMP) requirements by providing
stormwater and rainwater LID strategies for Development and Redevelopment projects as
defined under"Applicability."
The City Council of the City of Baldwin Park does ordain as follows:
Title 5 §52.13 of the City of Baldwin Park Municipal Code is amended in its entirety to read as
follows:
1
I. Definitions.
Except as specifically provided herein, any term used in Title 5 §52.13 shall be defined as that
term in the current Municipal NPDES permit, or if it is not specifically defined in either the
Municipal NPDES permit, then as such term is defined in the Federal Clean Water Act, as
amended, and/or the regulations promulgated thereunder. If the definition of any term contained
in this chapter conflicts with the definition of the same term in the current Municipal NPDES
permit, then the definition contained in the Municipal NPDES permit shall govern. The
following words and phrases shall have the following meanings when used in this chapter:
Automotive Service Facility means a facility that is categorized in any one of the following
Standard Industrial Classification (SIC) and North American Industry Classification System
(NAICS) codes. For inspection purposes, Permittees need not inspect facilities with SIC codes
5013, 5014, 5541, 5511, provided that these facilities have no outside activities or materials that
may be exposed to stormwater (Source: Order No. R4-2012-0175).
Basin Plan means the Water Quality Control Plan, Los Angeles Region, Basin Plan for the
Coastal Watersheds of Los Angeles and Ventura Counties, adopted by the Regional Water Board

Biofiltration means a LID BMP that reduces"stormwater pollutant discharges by intercepting
rainfall on vegetative canopy, and through incidental infiltration and/or evapotranspiration, and
filtration. Incidental infiltration is an important factor in achieving the required pollutant load
reduction. Therefore, the term "biofiltration" as used in this Ordinance is defined to include only
systems designed to facilitate incidental infiltration or achieve the equivalent pollutant reduction
as biofiltration BMPs with an underdrain (subject to approval by the Regional Board's Executive
Officer). Biofiltration BMPs include bioretention systems with an underdrain and bioswales
(Modified from: Order No. R4-2012-0175).
Bioretention means a LID BMP that reduces stormwater runoff by intercepting rainfall on
vegetative canopy, and through evapotranspiration and infiltration. The bioretention system
typically includes a minimum 2-foot top layer of a specified soil and compost mixture underlain
by a gravel-filled temporary storage pit dug into the in-situ soil. As defined in the Municipal
NPDES permit, a bioretention BMP may be designed with an overflow drain, but may not
include an underdrain. When a bioretention BMP is designed or constructed with an underdrain
it is regulated by the Municipal NPDES permit as biofiltration (Modified from: Order No. R4-
2012-0175).
2
Bioswale means a LID BMP consisting of a shallow channel lined with grass or other dense,

(11)Redevelopment Projects
9
a. Land disturbing activity that results in the creation or addition or replacement of
5,000 square feet or more of impervious surface area on an already developed site
on Planning Priority Project categories.
b. Where Redevelopment results in an alteration to more than fifty percent of
impervious surfaces of a previously existing development, and the existing
development was not subject to post-construction stormwater quality control
requirements, the entire project must be mitigated.
c. Where Redevelopment results in an alteration of less than fifty percent of
impervious surfaces of a previously existing development, and the existing
development was not subject to post-construction stormwater quality control
requirements, only the alteration must be mitigated, and not the entire
development.
d. Redevelopment does not include routine maintenance activities that are conducted
to maintain original line and grade, hydraulic capacity, original purpose of facility
or emergency redevelopment activity required to protect public health and safety.
Impervious surface replacement, such as the reconstruction of parking lots and
roadways which does not disturb additional area and maintains the original grade
and alignment, is considered a routine maintenance activity. Redevelopment does
not include the repaving of existing roads to maintain original line and grade.
e. Existing single-family dwelling and accessory structures are exempt from the
Redevelopment requirements unless such projects create, add, or replace 10,000
square feet of impervious surface area.
(D)Effective Date. The Planning and Land Development requirements contained in Section
7 of Order No. R4-2012-0175 shall become effective March 1, 2014. This includes
Planning Priority Projects that are discretionary permit projects or project phases that
have not been deemed complete for processing, or discretionary permit projects without
vesting tentative maps that have not requested and received an extension of previously
granted approvals within 90 days of March 1, 2014. Projects that have been deemed
complete within 90 days of March 1, 2014 are not subject to the requirements Section 7.
(E) Stormwater Pollution Control Requirements. The Site for every Planning Priority
Project shall be designed to control pollutants, pollutant loads, and runoff volume to the
maximum extent feasible by minimizing impervious surface area and controlling runoff
from impervious surfaces through infiltration, evapotranspiration, bioretention and/or
rainfall harvest and use.

a. Conserve natural areas;
b. Protect slopes and channels;
10
c. Provide storm drain system stenciling and signage;
d. Divert roof runoff to vegetated areas before discharge unless the diversion would
result in slope instability; and
e. Direct surface flow to vegetated areas before discharge, unless the diversion would
result in slope instability.
(2) Street and road construction of 10,000 square feet or more of impervious surface shall
follow USEPA guidance regarding Managing Wet Weather with Green Infrastructure:

the following:
a. Retain stormwater runoff onsite for the Stormwater Quality Design Volume
(SWQDv) defined as the runoff from:
i. The 85th percentile 24-hour runoff event as determined from the Los Angeles
County 85th percentile precipitation isohyetal map; or
ii. The volume of runoff produced from a 0.75 inch, 24-hour rain event,
whichever is greater.
b. When, as determined by the City Engineer, 100 percent onsite retention of the
SWQDv is technically infeasible, partially or fully, the infeasibility shall be
demonstrated in the submitted LID Plan. The technical infeasibility may result
from conditions that may include, but are not limited to:
i. The infiltration rate of saturated in-situ soils is less than 0.3 inch per hour and it is
not technically feasible to amend the in-situ soils to attain an infiltration rate
necessary to achieve reliable performance of infiltration or bioretention BMPs
in retaining the SWQDv onsite.
ii. Locations where seasonal high groundwater is within five to ten feet of
surface grade;
iii. Locations within 100 feet of a groundwater well used for drinking water;
iv. Brownfield development sites or other locations where pollutant mobilization
is a documented concern;
v. Locations with potential geotechnical hazards;
11
vi. Smart growth and infill or redevelopment locations where the density and/ or
nature of the project would create significant difficulty for compliance with
the onsite volume retention requirement.
c. If partial or complete onsite retention is technically infeasible, the project Site may
biofiltrate 1.5 times the portion of the remaining SWQDv that is not reliably
retained onsite. Biofiltration BMPs must adhere to the design specifications
provided in the Municipal NPDES Permit.
i. Additional alternative compliance options such as offsite infiltration may be
available to the project Site. The project Site should contact the Department of
Public Works to determine eligibility. Alternative compliance options are
further specified in City's Living Street Manual.
d. The remaining SWQDv that cannot be retained or biofiltered onsite must be
treated onsite to reduce pollutant loading. BMPs must be selected and designed to
meet pollutant-specific benchmarks as required per the Municipal NPDES Permit.
Flow-through BMPs may be used to treat the remaining SWQDv and must be
sized based on a rainfall intensity of:
i. 0.2 inches per hour, or
ii. The one year, one-hour rainfall intensity as determined from the most recent
Los Angeles County isohyetal map, whichever is greater.
e. A Multi-Phased Project may comply with the standards and requirements of this
section for all of its phases by: (a) designing a system acceptable to the
Department of Public Works to satisfy these standards and requirements for the
entire Site during the first phase, and (b) implementing these standards and
requirements for each phase of Development or Redevelopment of the Site during I
the first phase or prior to commencement of construction of a later phase, to the
extent necessary to treat the stormwater from such later phase. For purposes of
this section, "Multi-Phased Project" shall mean any Planning Priority Project
implemented over more than one phase and the Site of a Multi-Phased Project shall
include any land and water area designed and used to store, treat or manage
stormwater runoff in connection with the Development or Redevelopment,
including any tracts, lots, or parcels of real property, whether Developed or not,
associated with, functionally connected to, or under common ownership or control
with such Development or Redevelopment.
(E) Other Agencies of the City of Baldwin Park. All City of Baldwin Park Departments,
offices, entities and agencies, shall establish administrative procedures necessary to
implement the provisions of this Article on their Development and Redevelopment
projects and report their activities annually to the Department of Public Works.
