The National Pollutant Discharge Elimination System (NPDES) is the portion of the Clean Water Act that applies to the
protection of receiving waters. Under permits from the Los Angeles Regional Water Quality Control Board (RWQCB),
certain activities are subject to RWQCB enforcement. To meet the requirements of the Los Angeles County Municipal
Separate Storm Sewer System (MS4) Permit (R4-2012-0175), minimum requirements for sediment control, erosion
control and construction activities must be implemented on each project site. Minimum requirements include:
EROSION: Erosion from slopes and channels shall be controlled by implementing an effective combination of BMPs,
such as the limiting of grading activities during the wet season; inspecting graded areas during rain events; planting
and maintenance of vegetation on slopes; and covering erosion susceptible slopes.
SEDIMENT CONTROL: Eroded sediments from areas disturbed by construction and from stockpiles of soil shall be
retained on site to minimize sediment transport from the site to streets, drainage facilities and/or adjacent properties
via runoff, vehicle tracking or wind.
CONSTRUCTION MATERIALS CONTROL: Construction related materials, wastes, spills or residues shall be
retained on site to minimize transport from the site to streets, drainage facilities or adjoining properties by wind or
runoff. Runoff from equipment and vehicle washing shall be contained at construction sites unless treated to remove
sediment and pollutants.
NON-STORMWATER RUNOFF: Non-stormwater runoff from equipment and vehicle washing and any other activity
shall be contained at the project site.
EROSION AND SEDIMENT CONTROL PLAN (ESCP): Required for projects one acre or more. The ESCP must be
developed and certified by a Qualified SWPPP Developer (QSD).
HILLSIDE: Construction upon slopes 25% or more requires the implementation of additional BMPs to protect slopes
and prevent erosion and sediment runoff.
Minimum BMPs include: (1) Soil piles must be covered with tarps or plastic, (2) leaking equipment must be repaired immediately, (3) refueling must be
conducted away from catch basins, (4) catch basins must be protected when working nearby, (5) vacuum all concrete saw cutting, (6) never wash
concrete waste into the street, (7) keep the site clean, sweep the gutters at the end of each working day and keep a trash receptacle on site.
As the engineer of record, I have selected appropriate BMPs to effectively minimize the negative impacts of this project’s construction activities on stormwater quality. The project owner and contractor are aware that the selected BMPs shall be installed, monitored, and maintained to ensure their
effectiveness. The BMPs not selected for implementation are redundant or deemed not applicable to the proposed construction activity.

DEFINITIONS:
LID: Low Impact Development (LID) is a stormwater management strategy that emphasizes conservation and
the use of existing natural site features integrated with stormwater controls to more closely mimic natural
hydrologic patterns in residential, commercial, and industrial settings.
Development: Development includes any construction or demolition activity, clearing, grading, grubbing, or
excavation or any other activity that results in land disturbance.
Impervious Area: Surfaces that do not allow stormwater runoff to percolate into the ground. Typical
impervious surfaces include: concrete, asphalt, roofing materials, etc.
Hillside: A property where the slope is 25% or greater and where grading contemplates cut or fill slopes.
Single family hillside homes will require a less extensive plan. During the construction of a single-family
hillside home, the following measures are implemented:
a. Conserve natural areas
b. Protect slopes and channels
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
e. Direct surface flow to vegetated areas before discharge unless the diversion would result in slope
instability.
Green Streets: Any street and road construction of 10,000 square feet or more of impervious surface area.
Street and road construction applies to standalone streets, roads, highways, and freeway projects, and also
applies to streets within larger projects. These sites are required to develop a Green Streets Plan with the
following provisions:
a. Follow an approved green streets manual to the maximum extent practicable. Stormwater mitigation
measures must be in compliance with the approved green streets manual requirements.
Redevelopment: Land-disturbing activities that result in the creation, addition, or replacement of
impervious surface area on an already developed site.
Redevelopment does not include routine maintenance activities that are conducted to maintain the
original line and grade, hydraulic capacity, or original purpose of facility, nor does it include modifications
to existing single family structures, or emergency construction activities required to immediately protect
public health and safety.
Significant Ecological Area: An area in which plant or animal life or their habitats are either rare or
especially valuable because of their special nature or role in an ecosystem and would be disturbed or
degraded by human activities and developments. Also, an area designated by the City as approved by
the Regional Water Quality Control Board.
Maintenance Agreement and Transfer: All developments subject to LID requirements must provide
verification of maintenance provisions for Structural and Treatment Control BMPs. Verification at a
minimum shall include:
Recorded maintenance covenant; and
The developer’s and/or owner's signed statement accepting responsibility for maintenance until the
responsibility is legally transferred; and
A signed statement from the public entity assuming responsibility for Structural or Treatment Control
BMP maintenance and conduct a maintenance inspection at least once a year.
BMP: Best Management Practices (BMPs) are practices or physical devices or systems designed to
prevent or reduce pollutant loading from stormwater or non-stormwater discharges to receiving waters,
or designed to reduce the volume of stormwater or non-stormwater discharged to the receiving water.
Surface Area: The surface area is the total footprint of an area. Not to include the cumulative area
above or below the ground surface.

Best Management Practices (BMPs) have been incorporated into the design/maintenance/construction of this project
to accomplish the following:
1. Minimize impacts from stormwater runoff on the biological integrity of Natural Drainage Systems and water bodies in
accordance with requirements under CEQA (Cal. Pub. Resources Code § 21100), CWC § 13369, CWA § 319, CWA § 402(p),
CWA § 404, CZARA § 6217(g), ESA § 7, and local government ordinances.
2. Maximize the percentage of pervious surfaces to allow more percolation of stormwater into the ground.
3. Minimize the amount of stormwater directed to impermeable surfaces and to the MS4.
4. Minimize pollution emanating from parking lots through the use of appropriate Treatment Control BMPs and good
housekeeping practices.
5. Minimize breeding of Vectors
6. Reduce pollutant loads in stormwater from the development site.
I certify that this Low Impact Development Plan and all attachments were prepared under my direction or supervision in accordance
with a system designed to ensure that qualified personnel properly gathered/evaluated the information submitted.
Post Construction / Maintenance Certification
As the responsible party, I certify that the proposed BMPs will be implemented, monitored and maintained to ensure their continued
effectiveness. In the event of a property transfer, the new owner/lessee will be notified of the BMPs in use at this site and I will include written conditions in the sales or lease agreement, which requires the new owner (or lessee) to assume responsibility for maintenance
and conduct a maintenance inspection at least once a year. The information contained herein is, to the best of my knowledge and
belief, true, accurate, and complete.
In consideration of the execution of City of Arcadia approval of the proposed Low Impact Development (LID) Plan including any
proposed treatment system, the applicant hereby agrees to indemnify, save and keep the City of Arcadia, its officers, agents and
employees free and harmless from and against any and all claims for injury, damage, loss, liability, cost and expense of any nature whatsoever, which the City of Arcadia, its officers, agents, or employees may suffer, sustain, incur, pay out as a result of any and all
