STORMWATER MANAGEMENT PROGRAM
1. INTRODUCTION
7.7 Ovdrview
This document preseats the City o£Auburn's Stormwater Dianagement Program (SWMP): Preparatiori and :
tnaintenance of this SWN1P is requiied bp the Washington State Departinent of Ecology (Ecology) as a condiuon of the Western Washington Phase II Munidpal Stormwater Permit (the Phase II Permit). The
Phase II permit coners discharges from regulated small munidpal separate storm sewer sqstems (NZS4s).
Based on criteria outlined in the Phase II Pernut, Ecology considess the Ciry of rlubum xo be an operatoi of.
a small MS4,:and,thexefore required to obfain permit coverage. `
Each municipality's permit.for, discharging stormwater is designed to reduce the discharge ofpollutants,
protect water quality, and meet the requirements of the federal Clean Water Act.
Appendix A includes acronyms and definirions from the Permit to help the reader understand the City's
Stormwater Management Program..
1.2 Regaeiatory.8aclsground
The Naaonal Pollutant Discharge Elimination System (NPDES) permit prograin is a requirement of the
federal Clean Water Act, which is uiteiided to protect and restore wateis for"`fishable, swunmable" uses. The
federal Environmental Protection Agenry (EPA) has delegated pernut authoritp to state environmental
agencies, and these agencies.can set permit conditions in accordance with and in addition to ihe minimum
federal requireraents. In Washingtbn, the NPDES-delegated permit authoriry is the Washington State
Depaztment of Ecology (Ecology).
Municipalities with a populatioii of over 100,000 (as of the 1990 census) have been designated as Phase I
communiries and must comply with Ecology's Phase I NPDES NIunicipal Stormwater Pernut. With Auburn's
1990 census falling below the 100,000 tlireshold, the City must comply with the Phase II blunicipal
Stoimwater Permit: rlbout 100 oEher municipalities in Washington must now comply with the Phase II
Pernut, along withAuburn, as operators of small municipal separate stoan sewer systems (MS4s). Ecology's
Phase II Muniupal Stormwater.Permit is available on Ecology's website at
http: / /www.ecy.wa.gov/12roQrams /wq /stormwater/municipal%12haseIIavw/ww3ihupermit.html
The Permit allows muaicipalities to discharge stormwater runoff from municip'al drainage systems into the
state's water bodies (e.g., streatns,:rivers, lakes, wetlands) a's long as muiiicipalities unpleinent prog;acns to
protect water quality by reducing the discharge of "non-poinf souree" pollutants to the "ma.eitnum extent
pracucable" (MEP) through applicarion: of Pernut-specified "best managetnent practices"(BM'As). The BM'Ps
specified•in the Pemut aze collectively refened to as the Stormwater ManagemenrPrograzn (SWMP) and
grouped under the follovving Progtam components: -
■ Public Educarion and Ouueach: Public Involvement
~ Illicit Discharge Detecrion and Elimination

° Conttolling Runoff from Development, Redevelopment, and Construction Sites
■ Pollution Prevention and Ntuniapal Operation and Maintenance
■ Monitoriag
The Permit issued by Ecology became effecrine on Feb.ruary 16, 2007, was modified on June 17, 2009 and '
expires on February 15, 2012. The Permit requires the City to report annually (March 315t of each year) on
pmgress in SWN1P implementation for the previous year. . The Permit also requires submittal of
documentation that describes proposed SWNIP activities foz the. coming year. This document contains the
City's proposed activities for 2011. Implementarion of various Permit conditions is staggered throughout the
five-year Permit term from February 16, 2007 througk February 15, 2012. The Permit arill be revised and
reissued at the end of this period. -
1,3 City of Auburn /aegulated Area
The Western Washingtoa Phase II Pemut applies to operators of regulated small MS4s that discharge
stormwater to waters of Washington State located west of the crest of the Cascade Range (west of t.he eastexn.
boundaries of Whatcom, Skagit, Snohomish, K.ing, Pierce, Lewis and Skamania counries). Fo=.cities, the •
Permit requirements extend to those areas of each City tliat drain to MS4: Most of Auburn d=ains to MS4s' ~
that ultimately discharge into the Green River, the White Rivex, or 1~Iill Creek: In addition; some portions of
the Ciry drain to regional infiluation basins. -
' Aiance . . .
1.4 Tota► Maximum Daily L.oad (TMDL) Cornp 1
The federal Clean Water tlct requires that Ecology establish "Total Maxixnum Dailp Loads" (BIIDL) for
rivers, streams, lakes, and marine waters that don't meet water qualiry standards. r1 TMDL is a calcularion of
the maxitnum amount of a pollutant that a water body.can receine and still meet water quality standards. •
After the T'NIIDL has been calculated for a.given water body,;Ecology determines how much each source
must reduce its dischazges of the pollutant in order bring the avater body back into,compliaace with the water -
qualitp standards. The C1ean. W'ater Act requires that,T1'IDL requirements must be included in.the NPDES
permits for dischaigers into the affected water bodies. ;
Stormwater discharges covered .under this pemut are required to unplement actions. necessary to achieve the
pollutant reductions called for in applicable TMDLs, Applicable TMIDLs are thgse,appioved by the EPA
before the issuance date of the Permit or which have been,approved by the EPA"prior. to the date the .
pesmiftee's applicarion was received by Ecology. Information on Ecology's Ti~IDL program is available on
Ecologg's website at www.ecy.wa.gov/pro,grams/wg%tmdL
The current permit does not contain any TN1DL requirements for the City of Auburn. However, Ecology
has identified several water bodies that do not appear to meerthe water quality standards: If Ecology
establishes TNiDLs for one ar more of these water bodies prior.to 2012, tlie next nersion of the Permit may
contaiu addirional requirements specified in the 'TbfDL. 1:5 S IVIP lereplementatiort Responsibiligies The Utilities Engineering Division in the Public Works Department coordinates.the overall administration of
efforts to comply with Permit requirements. The work plan tables iu each Cfiapter provide the lead
departments for the associated task. Other major deparanent"s/divisions included in xhe 2011 SWNII'
implementarion include Maintenance and Operations (M&O), Human Resources (F-iR); Development
Engineering; Permit Centex, Informarion services (IS), and Parks.

progratn to detect and address illicit discharges.
■ Publicly list and publicize a hotline or other local telephone number for public reporting of spills and ,
other illicit discharges. Track illicit discharge reports and actions taken in response through close-out,
including enforcement actions.
• Train staff on proper IDDE response SOPs and municipal field staff to recognize and xeport illicit
dischazges.
■ Summarize all illicit discharges and connecrions reported to the Ciry and response acrions taken,
including enforcexnent actions, in the rlnnual Compliance Report; identify any updates to the SWMP.
5.2 Current Compliance Activities
The City has activities and programs that meet many of the Permit requirements. The cunent compliance
activities associated with the Permit include:
■ The City has completed some of the mapping required for the Permit. The City also has an SOP for
keeping the municipal separate storm sewer system map and inventory up-to-date.
• City codes and standards already have sections that address the required illicit discharges and civil

The Pesmit (Secrion S8) does nor require municipalides to conduct water qualiry sampling or other testing
during this permit term; with the following exceptions: `
■ Sampling or testing required for characterizing illicit discharges pursuant to the SWi~II''s IDDE
condirions. ,
a Water qualiry monitoring required £or compliance with Total.Maximum Daily Load (IMDL)
conditions (water quality:clean up plans). - The current Permit doesnot reguire that Auburn perform
nfDL-related monitoring because Ecology has not established TMDLs for water bodies that ieceive
stormwater runoff from the Ciry.
• Preparing future comprehensive, long-term water quality inonitoring plan including tavo components:
1) stormwater monitoring and 2)`targeted Stormwater bianageinenrProgram effectiveness monitoring.
■ By the 4t" Annual Compliance Report (March 31, 2011), Auburn is required to idenrify two outfalls or
conveyances where permanent stormwater sampling stauons can be installed and operated for future
monitoring. The Ciry is also required to develop plans to monitor stoxmwater, sediment, and receiving
water for physical, chemical, and/or biological characterisucs. One outfall must represent high-density
residential land use, and the other commercial land use.
° To monitor SVUNII' effectiveness, the City will need to idenrify two suitable Program quesrions and
sites where targeted Program effecdveness monitoring can be conducted and develop a monitoring
plan for these quesuons and sites. The proposed effectiveness monitoringis required to answer the
following types of questions "
• How effecuve is a specific targeted action or a narrow suite of acrions? • Is the Stormwater Management Program achieving a:targeted,environmental outcome?
In addition, the Ciry is required to provide the following monitoring and/or assessment data in each annual
report:
° r1 descriprion of anp stormwater monitoring or studies conducted by the City during the reporting
period. If stormwater monitoring was cqnducted on behalf of the City, or if studies or investigations
conducted by other entiues were reported to the Ciry, a brief description of the type of information
gathered or received shall be included,in the annual report.
• An assessment of the appropriateness of the best managementpractices idenrified by the City for each
connponent of the SVUl`1P; and any changes made, or anricipated to be made, to the BMPs that were
previously selected to implement Ehe SWNiP and why.

introduction
The Western Washington Phase II Munictpal Stormwater Petmit (Phase II permit) regulates stormwater
discharges for.small munfcipal separate storm sewer systems (MS4s) as established in Code-of Federal :
Regulations (CFR)'Title 40,'Part:122.26. The Phase Il permit, issued in 2007 and modified in 2009,
includes requirements (S9.E4.a) for permittees to summarize identified barrlers to the use of low-
impact development (LID) in their jurisdictlons and measuresto address these barriers. These are '
described in Section 2.
Permit condition S9.E.4.b requiresthatthe permittee complete a reportthat describes currently _
available LID practices; potential or planned non-structural LID techniques, goals, and metrics; and
schedules for implementation. Thls report can be prepared individually or in cooperation with other
permittees. This report is provided in Section 3.
The City,of Auburn (City) prepared this document to meet the Permit S9.E.4.a and S9.E.4.b
requirements.
1.1 Background .
L1D techniques can help sites mimic the hydrology and water quality of pre-developed conditions.
However, due to site conditions or other obstacles, LID cannot be implemented everywhere. The .
Wash(ngton State Department of Ecology (Ecology) has requfred permittees to implement UD
techniques °where feasible." This document is the first step in determining where LI.D implementation
appears feasible. Although the City cannot control barriers sucfi as soil infiitration rate, high
groundwater table, or steep slopes; it can manage codes and standa"rds to allow for LID
implementation where feasible.
1.2 Purpose
Special ConditionS9.E4 of the Phase II permit requires permittees to submit an LID barriers report
with the annual report by March 31, 2011, that includes the following information:
. a summary ot identified barriers to the use of UD within the area covered by the permit and
measures to address these barriers
• a report describing: _
- LID practices that are currently.available and that can reasonaply be implemented within this
permit term
- potential or planned non-structuraf actions and LID techniques to prevent stormwater impacts
goals and metrics to identify, prom.ote, and measure UD use
- potential or planned schedules for the permittee(s) to require and implement the non-structural
and LID techniques on a broader sctile in the future.
fcology suggests that permittees focus this task on preparing to implement LID requirements expected
in the next permit cycle.

Section 2
Potential LID Barriers and Measures to Address Them
This section discusses some barriers that could apply to Auburn tc make LID implementation
infeasible. This section aiso includes suggested actlons to remove those barrters and Includes potentlal
actions by others (e.g., Ecology, contractors, and developers) as well as the City.
Many current City codes and standards were written before current LID practices were developed. A
portion of the City's codes and related documents have been reviewed to identify chatlenges to
implementing. The documents reviewed Included:
. Auburn City Code (ACC) .
. Auburn Design Standards (ADS)
. 2009 Auburn Stormwater Managemerrt Manual (ASWMM)
. Internationai Bullding Code (IBC).
Several codes and sections may need to be revlsed to remove barriers to UD implementation. As the
City moves forward with LID impiementation, the identified barriers will be addressed during the
expected timelines set forth in the forthcoming 2012 Phase 11 permit. The identified codes, barriers,
and potential measures to remoVe those barriers are summartzed in Table 1.
All potential measures must still be evaluated to ensure that they remain conststent with City
objectives, including transportation, safety, and economic goals.

Clty of Auburn low-lmpact Development Barriers Section 2
The foilowing barriers are more general and not necessarily specificalty qlled out in City codes or
standards.
LID deflnitions: There is some uncertainly about what acttvitles and best management practices
(BMPs) are included In LID, so it would be beneflcial if Ecology provided more clarification on defining
UD. .
Perceptions of compromised public safety and property damage: Some people percetve certain UD
techniques as potentially compromising pubiic safety. Some concerns include reduced emergency
vehicte access/response by using "narrow" streets to reduce impervious area, and exacerbating
landslfde potential and causing water damage on adJacent properties by using inflltration and
dispersion. Ecology and the Puget Sound Partnership should consider mounting a public awareness
campaign to inform the publ)c about the benefits and risks of UD techntques.
LID credit calculatlons: Ecology is working to reflne LID credits to be used in reducing detention storage
volume and for other potential LID incenttves. Some LID credlts may be available only on lots with an
area greater than 1 acre and relatively few such lots are located in residenttal neighborhoods within
the city. Ecology should compfete its work to define the allowable UD credit calculation. LID credits against local stormwater management fees could significantly reduce available funding for utility
operation and maintenance activities.
City incentives: Current codes do not allow for incentives for property owners or developers to
implement LID measures.
Insufflcient areas on smaller lots: Certain LID techniques may not be appropriate for application on
smaller lots. The City shoutd develop a strategy for assessing small-lot feasibility.
Poorly draining soils: Many areas of the City have soils that are inappropriate for implementation of LID
measures that require infiltration. To assist property owners, the City should consider developing a
strategy for identifying such areas (perhaps involving definition of appropriate soil conditions, mapping
areas of suitabie soils, and/or defining how to perform onsite soil suitability analyses).
Moderate and steep slopes: Some areas of the city have slopes that might be too steep for certafn
infiltration and flow attenuation LID options. To asslst property owners, the City should consider
developing a strategy for identifying such areas (perhaps involving definition of appropriate slope
condltions, mapping areas of suitable slopes, and/or defining how to perform onsite siope suitability
analyses).
Unstable slopes: Some areas of the city might be inapproprfate for certain infiltration and flow
attenuation LID options due to slope instability. To assist property owners, the City should consider
developing a strategy for identifyfng such areas (perhaps involving definition of appropriate slope
stabflity conditions, mappfng areas of sultable slope stability, and/or defining how to pertorm onsite
slope suitability analyses).
Aquifer and wellhead protection areas: Some areas of the city require aquifer and welihead protection
to ensure adequate suppNes of safe drinking water. To assist property owners, the'City should consider
developing a strategy for identifying such areas and measures to protect them consistent with Code
sections addressing critical areas building requirements.
2-5
City of Auburn Low-Impact Development Barriers Sectton 2
High groundwater and ground/surface lnterflow: Some areas of the city have high groundwater and
ground/surtace fnterFlow conditlons that may preclude certain infiltration, flow attenuation, and flow
reductton UD opttons. To assist properly owners, the City should conslder developing a strategy for
identlfying such areas (perhaps invofving definitlons of approprlate groundwater conditlons, mapping
areas of suitable conditions, and/or deflning how to perform onstte grcundwater suitability anatyses).
Local LID deslgner and contractor experttse: Local experience with UD design and construction is
ltmited. The State shouid provide training to increase the pool of knowledgeable LID deslgners,
installation and maintenance contractors, and local government permit reviewers.
Pertormance, reliability; Iffe-cycle cost, and unintended Impacts: Earty stormwater management efforts
, using some UD techniques (such as infiltration) achieved limited success: Perceptions exist that LID
! technique pertormance may be difficult to predict and that LID facilities may be susceptible to failure,
I may have rehatively high repfacement costs over time, and may negatively affect groundwater quality.
Moreaver, failure of LID measures on private land couid lead to public drainage and water quality
problems that requlre expensive capital tmprovement projects to address. The State should provide
, monitoring to better understand LID performance and help with UD education efforts.
Properly owner education: Many property owners do not clearly understand the maintenance
requirements for LID facilities. Local govemments need the resources to provide those property owners
; with necessary information on LID systems and local conditions affecting those systema
Code development Current codes do not cover alt of the potential LID BMPs, so new codes may need
to be developed. Pctential code gaps include green roofs and cisterns. j
I Training and code development The codes, standards, manuais, and standard operating procedures
may need to be updated to address the barriers discussed above. New trafn(ng programs wtll be
necessary to teach City staff about updates.

Section 3
LID Report: Practices, Goals, Planned Actions, and Timelines This section addresses the requirements of Phase q permit conditians S9.E.4.b.1 through S9.E.4.b.iv.
These are: LID practices available now; potential future LID practices, goals, and metrics; and
schedules. The information contained ln this section does not constitute commitments or
requirements.
. 3.1 LID Practices Currently Available
"LID practices" broadly refer to UD as deflned In the Phase II Munlcipal Stormwater Permit. LID
practices include both non-structural actlons and LID technfques. The City of Auburn is open to all LID
practices where feasible as allowed by local codes and standards. This report section lists LID practices
currently employed, allowed, or requlred, as welf as those that could be implemented In the future.
Auburn LID projects include:
• parking lot permeable pavement, concrete, and asphalt
• public project rain gardens
. private project rain gardens
. pubiic roadway (in design).
The City of Aubum makes development project proponents aware of LID options at pre-applicatlon
meetings and encourages the use of UD where feasible.
3.2 Potential or Planned Non-Structural Actions and LID Techniques
This section of the report looks beyond the current permit cycle and explores opportunities for actions
and techniques that could be enhanced in the future or are not currently in use. .
Potential actions for future enhancement of LID practices include the following:
• assess lot coverage requirements for opportunities to take advantage of clustering and reducing
impervious surfaces
• assess the feasibiliry of reduced roadway widths
. employ lot setbacks totaling 15 feet on both sides of lot lines
• implement a credit transfer program
. install green roofs '
. install cisterns
. install permeable pavement roadways.
The City will continue to encourage small scale engineered facilities and devices or installations that
are built for the purpose of mimicking pre-development hydrologic functions through its project pre-
application pracess. It is anticipated that Ecology will be revising the Western Washington Stormwater
Management Manual to update and bring more clarity to implementation of LID techniques. The City
will update the Auburn manual to reflect any changes.

Management Program (SWMP) Effectiveness Monitoring
This monitoring plan has been prepared to comply with the requirements of Section S8 .
,
of the Westem Washington Phase II Municipal Stormwater Permit effective .February
16, 2007,and modified June 17, 2009. The Permit`include5 reguirements for permittees
to prepare.to conduct a, monitoring program in future. permits; The Phase II Monitoring Program deseri6ed in Section S8.C includes two types of monitoring:
1. Stormwater Monitorina (S8:C.1.a): requires pennittees to identify sifes suitable

types, and on known water quality probiems. and/or targeted' areas of interest for
future monitoring. .
2. Tarqeted SWMP Effectiveness Monitorinp lS8.C:1.b): requires permittees to
identify ques6oos that monitoring may answer to determine the effectiveness.of ;
specific components of their Stormwater Management Program (SWMP):, The permittee must identify sites for monitoring and create monitoring plans fo ~ .
answer at least finro effectiveness questions. The following sections describe the City's plan to meet each ofithe above requirements. "
While the City prepared tfiis plan fo complv with`its permit conditions, the Citv reserves
- the riqht to modifv the plan '(in.part or in its entiretv) to reflect pofential chanQes in Cifv `
- _
priorities. The Citv is concerned that prepannq a stormwater monitorina alan without a
clear problem statement and supportinq experimental design mav7ead to collectinq the wronq data and/or inconclusive results. The Citv.will discuss anv potential chanqes with
EcoloQV before modifications are made to this plan.
STORMWATER MONITORING (S8.C.1.A) .
Permittees shall select outfalls orI conveyancesbased on known water quality prablems
and/or targeted areas of interest for future monitoring; The, Permittee shall document:
. Why sites were selected;
e Possible site constraints for installation of and access to monitoring equipment;
• A brief description of the contri6uting drainage pasin including size in acreage,;

~ The City has selected twa sites for stormwater sampling to meet the requirements of
i S8.C.1.A. One location represents higli-density residential land use and the second
' represents commeraal land use.
l _
Site 1: Mill Pond Outfall to the White River
This site, represents high-density residential land use and was selected because of
( suspected fecal coliform'bacteria contamination. Sampling af this location will be
~ accomplished using grab sampling metliods because automated sampling is not
I suitable for fecal coliform analyses. The City does not anticipafe, any constraints to grab
~ sampling at this site. •
~
;
~ If flow-weighted composite sampling is deemed necessary for some reason, tfiis site
would require insta((ation of a stable, measurable ctiannef. cross section, power would
~ need to be brought to the site, and a method to secure equipment from theft and
i vandalism would be needed:
(
; The drainage basin is south of the White River in the Lakeland Hills neighborhood of
! Aubum. It is approximately 495 acres. The primary land use is high-density cesidential
(approximately 318 acres). The basin also.includes approximately 94 acres of .
commercial and 83 acres of mostly wooded open space.
The water quality concems for this site stem from TMDL work on the White River.
' Water qualify sampling by Ecology in 2006 and 2007 suggest the concentrations of
fecal coliform bacteria at the Mill Pond outfall exceed water quality standards. ~ Site 2: H Street NW Ditch Line
;
j This site was selected because it meets the criteria for commerciai land use and is a
; suitable location for permanent installation and operation of flow weighted composite •
; sampling equipment. The site conveys stormwater drainage from the downtown
i commercial disfict and the adjoining residential and industrial areas. There are no =
~ known water quality problems at this site. This site is expected to have water quality `
i comparable to the water quality of other commercial urban land uses.
! To perForm flow weighted composite sampling this site would require installation of a i stable, measurable channel cross section. Power would need fo be brought to the site,
~ and a method #o secure equipment from theft and vandalism would be needed.
1 The drainage basin encompasses approximately 373 acres. Land use within the basin
j is approximately 44% commercial, 40% industrial, 10% public / open space, and 6%

TARGETED SWMP EFFECTIVENESS MONITORING (S8.C.1.B)
Special condition S.8.C.1.13 requires that the Permittee develop a monitoring plan
designed to answer two questions pertaining to the effectiveness of the SWMP. For
each question, the plan must contain the following elements:
. A statement of the question, an explanation of how and why the issue is
significant to the Permittee and a discussion of whether and how the results of
the monitoring may be significant to other MS4s.
• A specific hypothesis about the issue or management actions that will be tested.
• Specific parameters or attributes to be measured.
• Expected modifications to management actions depending on the outcome of
hypothesis testing.
The following table summarizes the two questions and the types of monitoring to be
perFormed. Question Monitorin
Are current flow control requirements appropriate Physical channel monitoring at key cross secfion
for preventing channel erosion in Mill Creek? locations.
Do stormwater discharges from Mili Pond exceed Grab samples of water entering the Mill Pond vault
water quatity criteria for fecal coliform? and water entering the White River from the Mill
Pond outlet
Question 1: Are current flow control requirements appropriate for preventing
channel erosion in Mill Creek?
Substantial portions of the Mill Creek basin, particularly the lower areas along the valley
floor, have bep.n developed for many years. However, erosion and channel instability
have not been observed in the lower portions of Mill Creek, perhaps because of the flat
gradient and/or unique geology of the area. The purpose of this monitoring is to assess
the stability of Mill Creek and to evaluate the need for flow control criteria to protect the
channel.
Hypothesis: The current flow control standard is unnecessarily stringent for
preventing erosion in Lower MiII Creek.
This is a significant issue to the City of Auburn because most of the highly urbanized
areas located in the City's downtown discharge to Mill Creek. The development and
redevelopment of these core areas of the City is vital to its existence and requiring an
unnecessarily stringent flow control standard places a huge financial burden on
landowners.

~ Physical channel characteristics will be- measu'red and recorded periodically at selected
~ locations along the Mill Creek main,stem. Cross-sections will ;be established to monitor
channel geometries and bed slope. Additional characterizations will be made with
~ regartl to channel incision, channel substrate: composition, and bank stability.
` Procedures for physical channel monitoring would be based on Appendix C of the
~ Pierce County Coun,tywide Water Qual'ity Monitoring Plan (Brown`and Caldwell, 2007).
The expected modifications to management acfions would be to, develop, a basin- •
specific standartl for flow control in tlie areas draining to lower Mill Greek.
~ Question 2: Do stormwater discharges from Mill Pond exceed water quality
criteria for fecal coliform? ~ This is a significant issue to the City of Aubum because fecal coliform data collected for
the White River TMDL are inconclusive as to the source of potential contamination. The
~ City wants to measure fecal coliform levels fot discharges from the MiII Pond outfall to
i evaluate whether fhey exceed water quality standards.
~ Hypothesis: Mill Pond stormwater diseharges do not exceed water quality" . ! criteria for fecal coliform. ~
~ The City will use grab sampling methods to collect the samples from the outfall to the_ -
pond. Samples will be analyzed using a commercial Jaboratory.
;
' If sampling determines that discharges from the City's.MS4 exceed water quality
` standards for fecal coliform, then the City-may conduct a more detailed investigation
; into the source of the contamination. The,City anticipates.that additional investigations,
; if needed, w'ill include microbial source tracking methodologies,.and source tracking to
try and determine where_the contamination is coming from and how to reduce it :
