PREPARED Public Works Director
RECOMMENDED ACTION: That the City Council set a Public Hering for March 5, 2003, to consider
adopting a resolution to approve City of odi's Stormwater Management
Program (SMP) as prepared by Black & Veatch Corporation and authorizing
the City Manager to approve submittal of a Notice of Intent {N I) to apply for
the National Pollutant Discharge Elimination. System (NPDE ) Phase 11 Permit Application to the
Regional Water Quality Control Board (RB).
BACKGROUND INFORMATION: The State of California Water Resources Control Board, in
compliance with Federal mandates, will require the City of odi,: as
well as other cities and entities, plus construction sites dlst.urbir
one or more acres, to obtain NPDES Phase 11 tormw ter permits by
March 10, 2003. The current application cost is $7,540, which is also the annual permit cost for
populations between 50,000 and 74,999.
Under the jurisdiction of the Central Valley Regional Water Quality Control Board., the State has
developed a general stormwater permit. The City intends to apply for the permit and will have five years to
implernent a storrnw t r program that will meet general Phase 11 requirements. Background on these
requirements was presented to Council at the March 25, 2002, Shirtsleeve Session.
The City has hired Black & Veatch Corporation as a consultant to assist the City with the preparation of a
Stormwater ter l n gement Program (attached) and Cather documentation necessary for obtaining: n
NPIDES Phase 11 permit. They have been working with the City on this project sine May 2002, As
intended and previously stated in the March 20, 2002, Council Communication, the City worked with
Black & Veatch in utilizing existing materials for completion of this work. Black & Veatch has completed
the necessary task$ listed below:
1. Summary of existing system, maintenance practices, and municipal code
2. Determine RWQQB requirements and prepare written summary
3, facilitate establishing goals and objectives
4. Prepare tormwate : Management Program
5. Prepare NPDES permit Notice of Intent and related forms
5. Estimate cost of stormw ter management activities and five-year implementation.
Details can be found on pages 11-41 through 11-43 under the Program Cost Summary
section of the City's Stormwater Management Program (attached).

Black & Veatch has also assisted in the development of the City's Best Management Practices (BMP).
Found in the appendix of theMPl these practices have been developed to assist the City in maintaining
our Ston ter Management Program and can be used as a source of information. Although having the
IMP in place is required by the RWQCB, the suggested practices are not mandatory and are provid d as
optional guidelines when dealing with and managing stormwater issues. City staff will develop
tormwat r Team that will be responsible for updating these practices by improving development
standards and by improving our own construction specifications. Since specific practices are not
mandatary, the I3MP will be reviewed and/or edited as needed due to technology changes and according
to the effectiveness of each practice while managing the City's stormwater program.
California's implementation of the Federal requirements has been delayed due to a recent Federal Court
decision. One of the issues was the lack of required public input in adopting tete SMP. Thin, staff is
recommending a public hearing on this item,

stor.m water management Program
Phase Il of the Natio. al Pollutant Discharge lirz�ination Syste�xa (NP ES) requires tla .pity of
Lard 1, and all ether small municipal separate storm sewer systems (MS4s) to obtain a permit for
storm water discharges. The City is required to develop and implement a Stormwater
Management Program (SMP) that describes best management practices (BMPs), measurable
goals, and firm -,tables for implementation in six. program areas: public education and outreach,
illicit discharge detection and elimination, public participation/inv tvement, constmcticm site
runoff control, post -construction runoff control, and pollution prevention/good housekeeping.
Additionally, the MS4 must reduce its discharge of pollutants to the Maximum Extent
Practicable (MEP) and perform inspections and monitoring. The following document is the
City's SNIP,
The BMfIs chosen were determined through a series of meetings, both public and internal,
Initially, City Staff met with Black & Veatch to discuss issues and project goals. Blade &
V,eaich then developed a series of BMPs which initially were presented to staff and there to the
general populous at a public meeting. No public comments were received following the meeting,
and the SMP was finalized,
Table 1-1 relates key B Ps the City has chosen to implement and the pollutants they will be
designed to address. The pollutant load reductions resulting from BMP implementation will help
ensure that the City meets NPOES requirements and that the Mokelurr e liver water will be a
protected ,source, suitable for drinking water supply for years to come.

Stoernwater Management Program
t
The passage of the Clean Water Act (CWA) in 1972 has led to dramatic increases in the water'
quality of the Nation's streams and rivers; however, degraded water bodies still exist. According
to the 1996 United States Environmental Protection Agency National Water duality inventory,
approximately 40 percent of the U.S. waters surveyed are considered to be impaired by at least
one of a wide variety of pollutants. Stonnwater runoff represents a significant source of this
contamination. Table 3-1 summarizes the pollutants commonly found in stormwater, their
sources, and potential impacts,

City of Lodi
The Mokelumne River drains a portion of the central western slope of the Sierra Nevada
Mountains to the Sacramento Delta and serves as a source of water supply for a large portion of
Northern California. The City drainage system is bounded by the Mokelumne River on the
North; Barney Lanae on the South; the CCT Railroad, Kettleman Lane and Highway 99 on the
Bast; and the Woodbridge Irrigation District (WID) Canal and approximately 2,600 feet west of
Sacramento Road on the West. 'The drainage area totals approximately 6,673 acres (10.4 sq.
mi). The population of the City is approximately 58,950.
As part of the Environmental Protection Agency's (EPA's) Phase II National Pollutant Discharge
Elimination System (!9PDES) requirements, Black & Veatch completed a Phase lI permit
application for the City. This document is the City of Lodi Stormwater Management Program
(SMP) that has developed from the pen -nit application. The SMP has three objectives! to
minimize the impact of stormwater drainage on the residents of Lodi, to minimize the negative
impacts of receiving water quality of the Mokelumne River, and to minimize the negative
impacts on the fish and wildlife habitat.
In carder to accomplish these objectives, the SMP is designed to reduce the discharge of
stormwater pollutants to the Maximum Extent Practicable (MEP), protect water quality, and
satisfy the appropriate water quality requirements of the Clean Water Act. The SMP includes the
development of BMPs in each of six categories, an implementation schedule, and measurable
goats to help the City ensure that the water discharged is of the highest quality that is
economically possible.
Pollutants are deposited on the ground surface through a variety of urban activities and
transported to nearby rivers and streams during periods of rainfall. Common pollutants found in
stormwater and addressed by best management practices (BMPs) include pesticides, herbicides,
microbiological contaminants, sediments, nutrients, and heavy metals. The Phase II program also
places special emphasis on the need to protect stormwater from the pollutants introduced through
construction site runoff. In compliance with the NPDES Phase II program, the City chose to
address the introduction of contaminants through six general BMP categories outlined in Section
4 of this report.
M
City of Lodi
Stormovater Management Program
The Summaries of Regulatory Requirements in this section are based on Federal Law and Draft
Waste Discharge Requirements from the California State Water Resources Control Board.
Before the SMF is implemented, a review of the final California Phase Ih NPDES Program
Requirements should be completed when they are published. Following the review, the SMP
should be modified as necessary.
The City will complete an individual permit to fulfill Phase II requirements. Individual permits
are designed to be used by those entities with specific, unique problems that cannot be
effectively dealt with under a general permit. They are required for Phase I "medium" and
"large" municipal separate storm sewer systems (MS4s), but are not recommended by the EPA
for Phase H program implementation. The permitee can submit an individual application for
coverage by either the Phase II MS4 program or the Phase I MS4 program. For individual
coverage under Phase II, the pernitee must follow Phase 11 permit application requirements and
provide an estimate of square mileage served by the system and any additional information
requested by the NPDES permitting authority.
Operators of regulated small MS4s are required to submit the following information in their NOi
or individual permit application:
® BMPs must specifically address each of the six minimum control measures as shown in
Table 4-1 below.
• Measurable goals must be established and listed in the application for each minimum control
measure
® Estimated timeframe in which actions to implement each measure will be undertaken,
including interum milestones and frequency must be given
• Name(s) of the person(s) responsible for implementing or coordinating the stornwater
program must be included.

Table 4-1-NPDES Phase I1 Requirements
Public Education and Distribute educational materials and perform outreach to inform citizens about the
Outreach impacts polluted stormwater runoff discharges can have on water quality.
Public Provide opportunities for citizens to participate in program development and
Partieipationthtvolvement implementation, including effectively publicizing public hearings and/or encouraging
a citizen representative on a stormwater management panel. _
Illicit Discharge Deteat.ion Develop and implement an ordinance making it illegal to convey non-stormwater
and Elimination discharges through the MS4, and prepare a plan to detect and eliminate illicit
discharges to the storm sewer system (includes developing a system map, and
informing the community about hazards associated with illegal discharges and
improper disposal of waste).
Construction Site Runoff , Develop, implement, and enforce an erosion and sediment control program for
Control i construction activities that disturb one or more acres of land. (Controls could include
I silt fences and temporary stormwater detention ponds.)
Post -Construction Runoff Develop, implement, and enforce a program to address discharges of post -
C ontrol i construction stormwater runoff from new development and redevelopment areas.
' Applicable controls could include preventive actions such as protecting sensitive
areas (e.g., wetlands) or the use of structural BMPs such as grassed swales or porous
pavement_
Pollution Prevention/Good Develop and implement a program with the goal of preventing or reducing pollutant
Housekeeping runoff from municipal operations. The program must include municipal staff
training on pollution prevention measures and techniques (e.g., regular street
I sweeping, reduction in the use of pesticides or street salt, or frequent catch -basin
cleaning).

4.1.1. Public Education and Outreach
An informed, knowledgeable community helps to ensure greater support and compliance and is
crucial to the success of a stormwater management. It is noted that the summary of Regulatory
Requirements is based on Federal Law and Draft Waste Discharge Requirements from the
California State Water Resources Control Hoard. Before the program is implemented, a review
of the final California Requirements should be completed.
4.1.1.1, Summaryof Regulatory Requirements
The NPD/S Phase ii regulations require that the City implement a public education prograrn to
distribute educational materials to the community, or conduct equivalent outreach activities
about the impacts of stormwater discharges on water bodies and steps the public can take to
reduce pollutants in stormwater runoff.
4J.Z Public Parficipatiorldinvolvemeelt
The EPA states that the public can provide valuable input and assistance to a regulated small

Management Program because it allows for broader public support, shorter implementation -
schedules, a broader base of expertise, economic benefits, and a conduit to other programs.
4.9.2.1. Summary of Regulatory Requirements
When implementing a public involvement/participation program, the City of Lodi must, at a
minimum, comply with state, tribal, and local public notice requirements. The City must also
must make copies of the General Permit and Stormwater Management Program available to the
public for review.
4.9.3. Illicit Discharge Detection and Elimination
Discharges from MS4s may frequently include wastes and wastewater from non-stormwater
sources. Illicit discharges enter the system through either direct connections (e.g., wastewater
piping either mistakenly or deliberately connected to the storm drain system) or indirect
connections (e.g., infiltration into the MS4 from failed sanitary sewer systems, spills collected by
drain outlets, or paint or used oil dumped directly into a drain). The result is untreated
discharges that contribute high levels of pollutants, including heavy metals, toxics, oil and
grease, solvents, nutrients, viruses, and bacteria to receiving waterbodies. EPA studies show
pollutant levels from these illicit discharges are high enough to significantly degrade receiving
water quality and threaten aquatic life, wildlife, and human health. It is important to note that
limited data on the Mokelumne River indicates its water is relatively pure and minimally
impacted by stormwater discharges.
4.1.3.1. Summary of Regulatory Requirements
To comply with 14PDES Phase 11 program requirements, the City of Lodi must:
Develop, implement, and enforce a program to detect and eliminate illicit discharges [as
defined at Sec. 122.26(b)(2)] into the small MS4.
If not already completed, develop a storm sewer system map, showing the location of all
outfalls and the names and locations of all waters of the United States that receive discharges
from those outfalls.
To the extent allowable under state, tribal or local law, effectively prohibit, through
ordinance, or other regulatory mechanism, non-stormwater discharges into the municipal
storm sewer system and implement appropriate enforcement procedures and actions.
* Develop and implement a plan to detect and address non-stonnwater discharges, including
illegal dumping, to the MS4 system.
® inform public employees, businesses, and the general public of hazards associated with
illegal discharges to the MS4 and improper disposal of waste.
* The City needs to address the following categories of non-stormwater discharges or flows
(i.e., illicit discharges) only if they represent significant contributors of pollutants to the small
MS4: water line flushing, landscape irrigation, diverted stream flows, rising ground waters,
uncontaminated ground water infiltration [as defined at 40 CFR 35.2005(20)],
uncontaminated pumped ground water, discharges from potable water sources, foundation
drains, air conditioning condensation, irrigation water, springs, water from crawl space
pumps, footing drains, Iawn watering, individual residential car washing, flows from riparian
habitats and wetlands, dechlorinated swimming pool discharges, and street wash water.
4-I5
City of Lodi
(Discharges or flows from fire fighting activities are excluded from the effective prohibition
against non-stormwater and need only be addressed where they are identified as significant
sources of pollutants, to waters of the United States.)
Polluted stormwater runoff from construction sites often flows to MS4s and is ultimately
discharged into local rivers and streams. During a short period of time, construction sites can
contribute more sediment to streams than can be deposited naturally during several decades. The
resulting siltation and the contribution of other pollutants from construction sites, can cause
physical, chemical, and biological hann to our nation's waters.
4.1.4.1. Summary of Regulatory Requirements
® The City must develop, implement, and enforce a program to reduce pollutants in stormwater
runoff to the MS4 from construction activities that result in a land disturbance of one acre or
larger. Reduction of stormwater discharges from construction activity disturbing less than
one acre must be included in the program if that construction activity is part of a larger
common plan of development or sale that would disturb one acre or more.
• The program must include the development and implementation of, at a minimum:
+ An ordinance or other regulatory mechanism to require erosion and sediment controls, as
well as sanctions to ensure compliance, to the extent allowable under state, tribal, or local
law;
Requirements for construction site operators to implement appropriate erosion and
sediment control (ESC) best management practices;
+ Requirements for construction site operators to control waste, such as discarded building
rnaterials, concrete truck washout, chemicals, litter, and sanitary waste, at the
construction site that may cause adverse impacts to water quality;
o Procedures for site plan review which incorporate consideration of potential water quality
impacts;
Procedures for receipt and consideration of information submitted by the public;
# Procedures for site inspection and enforcement of control measures (grading permits);
r A program to inspect construction sites and enforce actions against violators.
Post -construction storznwater management is necessary in areas undergoing new development or
redevelopment because runoff from these areas has been shown to significantly impact the
quality of receiving waterbodies. Many studies indicate that prior planning and design for the
minimization of pollutants in post -construction stormwater discharges is the most cost-effective
approach to storrnwater quality management.
4.1.5.1. Summary of Regulatory Requirements
* The City must develop, implement, and enforce a program to address stormwater runoff from
new development and redevelopment projects that disturb greater than or equal to one acre,
including projects less than one acre that are part of a larger common plan of development or

Ci(v of Lodi
sale, that discharge into the MS4. The program must ensure that controls are in place that
would prevent or minimize water quality impacts.
« The City must:
* Develop and implement strategies which include a combination of structural and/or non-
structural best management practices (BMPs) appropriate for the community;
® Use an ordinance or other regulatory mechanism to address post -construction runoff from
new development and redevelopment projects to the extent allowable under state, tribal
or local law;
4 Ensure adequate long-term operation and maintenance of BMPs.
The Pollution PreventionJGood Housekeeping measure requires the City of Lodi to examine and
subsequently alter their own actions to help ensure a reduction in the amount and type of
pollution that: (1) collects on streets, parking lots, open spaces, and storage and vehicle
maintenance areas and is discharged into local waterways; and (2) results from actions such as
environmentally damaging land development and flood management practices or poor
maintenance of storm sewer systems. This measure, while primarily meant to improve or protect
receiving water quality, can also result in a cost savings for the City by encouraging proper and
timely maintenance of storm sewer systems, which will help avoid repair costs from damage
caused by deterioration and neglect.
4.1 6J. Summary of Regulatory Requirements
The City must develop and implement an operation and maintenance program that includes a
training component which has the ultimate goal of preventing or reducing pollutant runoff :from
municipal operations. Using training materials that are available from the EPA, the State of
California, or other organizations; the program must include employee training to prevent and
reduce stormwater pollution from activities such as park and open space maintenance, fleet and
building maintenance, new construction and land disturbances, and stormwater system
maintenance.

5,1 City of Lodi
The City of Lodi is located in the San Joaquin Valley approximately 6.5 miles north of Stockton
and 35 mites south of Sacramento, adjacent to U.S. Highway 99. it covers an area of 10.4 square
miles, and as of January 2001, its population was 58,950. The City provides municipal and
public utilities, transportation, leisure, cultural, social services, and general government services.
Included in the City's municipal services are stormwater and flood control.
The City maintains an intricate, gravity -based stormwater system built around a number of
stormwater detention basins and disposal of runoff by pumping to the Woodbridge Canal, Lodi
Lake, or the Mokelumte River. The detention basins are scattered throughout the City and are
maintained as parks and recreational facilities during non -runoff periods. The following
describes the City's current stormwater system and serves as the basis for the Stormwater
Management program.
Table 5-1 shows the total number of catch basins and manholes in the City's stor awater system
for the past four years. On average, 33 catch basins and 28 manholes are added to the system
each year.
Table 5-1 - City Catch Basins and Manholes
5.3. Outlets
The City's stormwater drainage system includes 18 storm outlets to the Mokelumne River, Lodi
Lake, or the Woodbridge Irrigation District Canal, Table 5-2 and Figure 5-1 identify the outlets
and their locations throughout the City.

The WIT) Canal is the receiving water for a significant portion of the City's stormwater. The
Storrn Drainage Discharge Agreement (Agreement) between the City and WILL serves as the
governing document between the two entities and allows the City to discharge stormwater into
WID Canals for 40 years. The City is limited to discharging 160 cubic feet per second (cfs), as a
maximum winter discharge rate. The maximum winter rate per discharge site is 60 cfs. During
the summer WID uses The canal for irrigation purposes. Therefore, the City's discharge rate is
reduced to a maximum of 40 cfs total, not to exceed 20 cfs per discharge site. This can be
increased by giving WID notice 12 hours prior to discharge. Under the Agreement, the City has
the right to modify the existing Beckman and Shady Acres Pump Stations and to construct
additional discharge points to accommodate the service area.
On Tuesday, May 14, 2002 Black & Veatch met with Anders (Andy) Christensen, WID General;
Manager, to discuss any concerns regarding disposal into WID canals. Andy feels that as Ion- as;
the City is able to meet future water quality requirements and does not exceed the maximum
allowed flow, the Agreement will work well. Currently, he feels the main water quality
problems appear to be nitrates, most likely from lawn fertilizers, and suspended solids. Evidence
of the problem, including algal blooms below City outlets, can be found in the canals following
pumping of tire City's stormwater.

The City has experienced; localized flooding in the past. The 1700 block of Lockeford Street has
been a particularly troublesome area. Recent system improvements may have eliminated this
problem. Residential streets southwest of Peterson park have also been identified as areas that
experiences occasional flooding due to undersized pipes. In general, operation of the system has
shown that the City's sto rmwater pumps and detention basins are adequate for the runoff volume
in the system. leo system -wide modeling has been completed to confirm and predict operation of
the system as it expands.

6A Street Sweeping
Street sweeping is a regular maintenance activity performed by City employees, In March 2002,
tete City hired an additional maintenance worker and purchased a new sweeping truck for the
purpose of increasing street sweeping frequency. As a result street sweeping frequency
approximately doubled and is currently scheduled as follows: residential areas are swept twice
per month, parking tots and alleys are swept once per month, the downtown area is swept three
times per week, and major roadways are swept once per week. The City also uses a sidewalk
sweeper to remove debris from the downtown area.
The City is developing a plan to deal with vehicles that hinder street sweeping. At present, when
the City is unable to sweep an area due to vehicles in the street, notices are left on the vehicles.
If the parked vehicles continue to be a problem, letters will be sent to local property owners. If
the problem continues, temporary "No Parking" signs will be placed in the area, and vehicles
blocking access will be towed.
Private property owners are required to sweep their parking lots weekly.

The City sponsors and participates in the Lodi All Emergency Preparedness Expo, The Expo is a
free event featuring workshops and presentations from various safety and emergency response
organizations. It is designed to increase public awareness on a variety of issues, including
stormwater awareness.
In October 2000, the City of Lodi's Public Works Department began a local. Citizen Monitoring
Program of the Mokelumne River, where the City's storm drains enter the river. The "Storni
Drain Detectives" is a collaborative effort of the City of Lodi Public Works Department, State
Water Resources Control Board -Division of Water Quality, Lodi Lake Nature Area Docent
Council, and four local high schools. Monthly monitoring of nine locations along:. the
Mokelunme River and Lodi Lake is done by students and teachers, grades 7-12, and other
volunteers who have been trained by a program coordinator. Students are often given school
credit for participating in this program. Funding for the program comes from the City of Lodi's,

show the locations and sizes of pipes, and locations of pump stations, manholes, and inlets.
Storrnwater protection is currently dealt with in Title 13 Chapter 12 of the Lodi, Municipal Cade.
The Code sloes not adequately address the requirements of the Phase lI program. For that reason
the City must develop a new section of the ordinance, or a separate ordinance, that will address
the following I PILLS Phase II requirements:
Draft RWQCl3 requirements state that the City must:
• Adopt an ordinance, policy, or regulatory mechanism toprohibitnon-stormwatert discharges
into the storm sewer system and implement appropriate enforcement procedures and actions,
including conducting manufacturing and commercial facility inspections, to the extent
allowable under federal, state or local law.
• Adopt, maintain, and enforce an ordinance, policy, or other regulatory mechanism to require
erosion and sediment controls at the construction sites, as well as sanctions to ensure
compliance, to the extent allowable under federal, state or local law.
• Adopt and enforce an ordinance, policy, or other regulatory mechanism that requires projects
include the incorporation, and long-term operation and maintenance of appropriate long-term
BMPs.
Erosion Control for Construction
Developers are required to address erosion control within construction plan submittals, Typical
measures required on plans include:
• Construction vehicle access control
• Temporary berms/sandbags
* Material stockpile locations
• Sweeping schedules
* Hay wattles
1 The Draft Waste Discharge Requirements from the California State Water Resources Control Board makes
allowances for certain authorized non-stormwater discharges. Authorized non-stormwater discharges are certain
categories of discharges that are not composed of stormwater but are not found to pose a threat to water quality.
They include: water line flushing; landscape irrigation; diverted stream flows; rising groundwaters; uncontaminated
groundwater infiltration (as defined in 40 CFR §35.2005(20)) to separate storm sewers; uncontaminated pumped
;round water; discharges from potable water sources; foundation drains; air conditioning condensate; irrigation
water that is not reclaimed treated wastewater, springs; water from crawl space, pumps; footing drams; lawn
watering that is not reclaimed treated wastewater; individual residential car washing; flows from riparian habitats
and wetlands; dechlorinated swimming pool discharges; and discharges or flows from emergency fire fighting
activities. It should be noted that the City must prohibit the above outlined discharges if they are found to cause or
contribute to an exceedance of water quality standards or cause or threaten to cause a condition of nuisance or
pollution.

During construction, the owner/developer is responsible for erosion control throughout the
project. Typical provisions include:
* Removal of all sediment/soil deposited on existing paved roadways prior to leaving the work
site, if possible, and in all cases within 24 hours.
* Plowing or ripping of all lot pads (rear of hinge line) prior to October 1 to a depth of 2 to 3
inches.
* Placement of "rock bags" at 200 to 300' intervals to isolate sediment prior to October 1 or
threat of major rain prior to that date. Sediment to be removed weekly (or sooner, if large
accumulation occurs or another storm is predicted).
Numerous environmental and stormwater benefits can be achieved through effective use of urban
forestry, 'frees can act as natural stormwater management areas by filtering particulate matter
(pollutants, some nutrients, and sediment) and by adsorption of water. Urban forestry', also
reduces noise levels, provides recreational benefits, increases property values, and has been
shown to reduce petty crime and vandalism rates.
The City of Lodi Public Works Department attempts to maintain and protect trees. The City is in
the process of developing an Urban Forest Management Plan to assess the present condition of
the urban forest, provide cost projections for future maintenance, assist with the budget process,
and project and monitor changes in the forest over time. Not including those associated with
Capital projects, the City plants approximately 250 trees a year and removes between 30 and 100
trees.
The City has submitted an application to be included in the Tree City USA program. The
program requires the City to establish a Tree Hoard or Department, a Tree Care Ordinance, a
Community Forestry Program with an annual budget of at least $2 per capita, and an Arbor lay
Observance and Proclamation.
The Ivlokelumne River Watershed Owner's Manual was developed by the Lower Moke£umne

The City's erosion control requirements are
extremely developer -Friendly, requiring only
a small level o4' effort relative to other
comparable cities. However, the City's
construction standards are not adequate to
meet the requirements of the Phase II
program. Current City erosion control
requirements are minimal, designed mainly to
deal with the public nuisance caused by
sediment rather than protect receiving water.
Phase lI NPDES permit requirements will
require the City to develop a much more
comprehensive erosion control management plan. The City must find a way to implement the
requirements of the new program in a manner that not only meets NPDES requirements, but also
continues to meet the City's development goals.
The Draft Waste Discharge Requirements for Stormwater Discharges $om Small Municipal
Separate Storm Sewer Systems, issued July 12, 2002 by the California State Water Resources
Control Board, outlines the requirements the City must follow. The guidance requires the City to
develop, implement, and enforce a program to ensure controls are in place that will prevent or
minimize water quality impacts from stormwater runoff from construction sites. Within the
permit area, the program must apply to all construction projects that disturb greater than or equal
to one acre (including projects less than one acre that are part of a larger conm7on plan of
development or sale that would disturb more than one acre) and that discharges into the City's
Small MS4. At a minimum, the City must:
1. .Adopt, maintain, and enforce an ordinance, policy, or regulatory mechanism to require
erosion and sediment controls at the construction sites, as well as sanctions to ensure
compliance, to the extent allowable under federal, state or local law;
2. Require construction site operators to implement appropriate and effective erosion and
sediment control BMPs that utilize Best Available Technology (BAT) economically
achievable and the Best Conventional Pollutant Control Technology (BCT) to reduce or
eliminate stormwater pollution;
3. Require construction site operators to control all pollutant sources at the construction site
that may cause adverse impacts to water quality including, but not limited to,
construction materials waste, discarded building materials, concrete truck washout,
chemicals, fuel, titter, and sanitary waste;
4, implement procedures for pre -construction site plan and BMP review that incorporate
consideration of potential water quality impacts from construction activities;
S. Implement procedures for receipt of and response to information submitted by the public
regarding stormwater runoff impacts due to construction projects; and
6. implement procedures for site inspections and enforcement of control measures.

Control of floatable debris in stormwater has
been identified as one of the areas on which
the City would like to focus its efforts.
Heatable debris conies from a variety of
sources and can cause a variety of problems,
such as lowered efficiency- and hydraulic
capacity, aesthetic degradation of waterways,
possible toxic effects to local aquatic species,
and damage to human health or property, The
ultimate source of floatable debris in the City
stormwater system is litter generated from the
improper disposal of waste within the
drainage area.. latter left anywhere in the City
can ultimately enter the River or WID canal
and is therefore a cause for concern. The City will approach the problem with a variety of
BMPs, ranging from increased frequency of street sweeping to public education and mechanical
separation, as discussed in Section 11,
4-34
City of Lodi
The following outlines Phase ti NPDES requirements, the City's permit compliance strategy, :and
the measurable goals the City has developed to meet the requirements.
MI.9. Public Education and Outreach
The City will implement a two-tiered approach to public education communicating the
importance of storntwater quality protection to both adults and children in the community. The
developing program will need to be a partnership between the City and area schools.
Adults will be educated through a brochure or flyer possibly included as a mailer with a utility
bill from the City and available in City offices. These flyers will be delivered to customers by
the end of 2€ 0'). The flyer will identify those SMPs that an individual family can implement to
protect stormwater, and communicate the importance an individual family can have in protecting
natural resources. Potential topics to be covered include:
• Automotive wastes
• Car washing
+ Storage of pesticides
w Handling and use of pesticides
• Proper handing and disposal of pet and animal wastes
• Proper handing and disposal of grass clippings, leaves, and other yard waste
Following a brief educational session, local children will participate in a stormwater protection
poster contest to be held annually at local schools, following a brief educational session, local
students will be encouraged to participate in a poster contest with a theme relating to stormwater
protection. The results will be judged by City public works staff. The winning posters will be
posted on a billboard in City hall or other public place.
Additional public contact will be made through appropriate media and may include presentations
at a local theater or newspaper, The City recently agreed to participate in the production of a
video aimed at stormwater quality in the Central Valley. This video will be used by the City as a
public education tool -

Table 10-1 - Public Education and Outreach Measureable Goals
10.1.2. Public Participationlinvcalverrment
The City will involve the public in completing its storm drain labeling program in a manner
similar to the Eagle Scout projects previously completed. All storm drain inlets will be labeledr
by the end of 2005.
The City will establish a toll-free citizen reporting telephone number or an electronic form linked
directly to the Public Works Department. The hotline or form will be advertised through the
local media as a way for citizens to participate in protecting stormwater. A typical call to the
hotline might report a parked automobile leaking fluid, fresh concrete wash-out dumped onto a
City street; paint or oily sheen in the river, or organic debris (including pet waste) in a drainage
system of waterway. The City will then promptly respond and attempt to remedy the reported
problem_ A log of all reported incidents will be maintained and included in the annual NPDES
compliance report to RWQCB.
The City will also continue to fund and look for additional grant funding opportunities for the
Storm Drain Detectives Program.
Table 10-2 - Public participation/]nvolvement Measureable Goals
10-36
City of Lodi
y
The City will develop and implement a program to detect and eliminate illicit discharges into the
storm sewer system. This program will be based on an updated stormwater protection ordinance,
which will be developed in 2003 and put into place in 2004.
As a fast phase of the detection program, the City will identify problem areas based on citizen
complaints, visual screening, or water sampling from manholes and outfalls during dry weather.
Phase Il will involve tracking the detected contamination to its source. Methods that can find the
source of the illicit discharge include: dye -testing buildings in problem areas; dye- or smoke -
testing buildings; tracing the discharge upstream in the storm sewer; employing a field
verification program that shows that a building has been checked for illicit connections; or using
video to inspect the storm sewers for illicit connections. Following source identification, the
offending discharger will be notified in writing and directed to correct the problem within a
reasonable time frame. All steps taken under the plan will be documented to illustrate that
progress is being made to eliminate illicit connections and discharges to the MS4.
Table 10-3 - Illicit Discharge detection and Elimination Measureable Goals
The; City will include in their Storaiwater Protection Ordinance a section dedicated to
construction site runoff control. Ivey BMPs to be enforced by the ordinance are listed below and
detailed in the attachments to this report.
The ordinance will be structured in a manner that rewards compliance. Suggestions include
requiring a deposit prior to construction. The deposit would then be used to pay for any fines
that may result from improper construction practices. Funds remaining following completion of
construction will be returned to the contractor. Probable requirements of the City of Lodi
Stotmwater Protection Ordinance include:
• Construction entrance
® Tie wash facility
® Outlet protection
• Check dams
• Straw sedimentation barriers
10-37
s Inlet protection
® Sand and bmfifter bags
• Concrete washout
• 'iaining,
Details of each of the requirements can be found in the SMP package included in the Appendix.
Training on the program will be provided to City staff and contractors.
As part of the program, the City will also develop an inspection program to ensure contractors
are following the requirements of the ordinance.
Table 141-4 - Construction Site Runoff Control Measureable Goals
The City will continue to build detention ponds as the size of the City increases and stormwater
detention needs grow. The City will also continue its urban forestry program. These and ether
structural and/or nonstructural BMPs will be required by the Stormwater Protection Ordinance;
Potential BMPs are included in the attachments to this report and include SMP inspection and
maintenance, grass lined swales, and floatahle debris removal. The details of the program will
be identified in a Standard Urban Storm Water Mitigation Plan (SUSMP) that will apply to many
discretionary development and redevelopment projects that fall into categories identified in
Attachment 4 of the permit guidance.

To address the pollution from community car washes, the City will develop a program similar to
those of Icing and F{itsap Counties in Washington. The City realizes the fund-raising importance
of car washes to many community organizations. For that reason the City provides education
and offers devices such as the "Bubble Buster" or drain plugs to protect stormwater quality.
The City recognizes that stormwater pollution resulting from fund-raisers and personal car
washes, as well as disposal of chlorinated water from pools or other sources, may detrimentally
impact the quality of discharged water. The City will develop and implement a public education
program targeting these types of discharges in an effort to reduce their impact, and will consider
offering devices designed to prevent the discharge of car wash water to storm drains. Table 10-6
shows the goals of pollution prevention and good housekeeping practices.
