SUBJECT:
2010 SWM ANNUAL AUDIT REPORT - MASTER
STORMWATER MANAGEMENT POLICY
RECOMMENDATION:
That the 2010 SWM Annual Audit Report, prepared by AECOM be received and
endorsed and further;
That staff be directed to review the Stormwater Management Policy I-1135, dated
December 10, 2001 and present recommendation to Council on or before
December 31, 2011.
BACKGROUND:
In 1999, the City of Kitchener commenced a study to prepare a Master Stormwater
Management (SWM) Policy, which would assess existing approaches to stormwater
management, investigate options for modifying the current approach and create a City-wide
policy for SWM. The final report of the Master SWM Policy was approved at Council on
December 10, 2001 and subsequently filed as a Schedule 'B' Environmental Assessment under
the MEA Class EA.
As part of the Master SWM Policy, an annual audit report is to be completed each year to
summarize the practices carried out to date in each of the categories included in the Citywide
plan, namely:
The development or site plan applications for the year and associated SWM fees
collected.
The SWM facilities that have been constructed (or are in the process of being
constructed) over the last year. This includes new ponds, retrofitting of existing SWM
facilities and the installation of oil/grit separator units (OGS).
Stream rehabilitation works that have been carried out or are underway.
ë ó ï
REPORT:
The focus of the 2010 report will be on the following areas:
a) Work Completed with SWM Redevelopment/Infill Charge (Cash-in-Lieu)
b) Cash-in-Lieu Fee
c) 2010 SWM Audit Recommendations
a) Work Completed with SWM Redevelopment/Infill Charge (Cash-in-Lieu)
The purpose of the annual audit report is to indicate whether or not the SWM measures provide
the necessary water quantity control and water quality treatment of stormwater resulting from
infill/redevelopment sites. The audit is completed in conjunction with a review of the capital
budget and an assessment of the following year’s budget. The review lists the redevelopment
and infill drainage area for which SWM Redevelopment/Infill charge (Cash-in-Lieu) has been
collected, the drainage area serviced by the facilities built, and the drainage area serviced by
creek rehabilitation works.
At the end of year 2010 the total drainage area serviced by SWM works was 154.12 ha
compared with 116.14 ha drainage area for which City of Kitchener collected Cash-in-Lieu.
Although no new stormwater management improvements were funded by cash-in-lieu in 2010,
the drainage serviced by SWM retrofit/OGS is still larger than the cash-in-lieu drainage area
ensuring a net gain in stormwater improvements. This is a result of the sustained effort to
complete SWM retrofits and the implementation of other best management practices (BMP).
b) Cash-in-Lieu Fee
The SWM Redevelopment/Infill charges (Cash-in-Lieu) applies to all redevelopment and infill
sites that cannot connect to existing quality control facilities and it is to be used toward the
construction/retrofit of SWM facilities.
In 2009 Annual Audit Report the Cash-in-Lieu fee have been calculated to recognize the change
in percent impervious land cover for infill/redevelopment areas or additionally land use costs the
City would incur in acquiring land for SWM development. The analysis produced an average
Cash-in-Lieu cost fee of $75,350/ha.
It was recommended that the cash-in-lieu fee be possibly increased as per land cost analysis
but should not go above that which would deter the implementation of policy objectives
regarding preference for centralized SWM facilities and reduced privately owned onsite controls.
The 2010 cash-in-lieu fee was $24,845/ha. As ratified by Council, on February 14, 2011, the
2011 cash-in-lieu fee was increased to$31,056/ha effective March 2011 based on inflation and
actual costs of stormwater management facilities. A flat fee of 10% of the current SWM charge
($3,105/ha) is to be charged for all sites less than 0.1 ha.
ë ó î
c) 2010 SWM AUDIT RECOMMENDATIONS
A number of actions were identified in the 2010 audit and recommended to be implemented
next:
1. OGS and associated drainage area files to be updated to provide for identification of City
owned OGS units. This information will be incorporated into the ‘treated area’ analysis
included in a next 5-Year Report Card.
2. Preliminary Trend Analysis – Parameters with more than eight (8) years of data should
be analysed to provide an indication of increasing trends by site location and parameter.
This preliminary analysis should be completed to reduce the risk of identifying false
trends.
3. Other analysis potentially including upstream land use, impervious characterization
should be completed to identify variables and trends.
4. Stream walk assessments should be completed every five (5) years with the next to be
schedule for 2014-2015.
5. The dry weather outfall program should be re-evaluated.
FINANCIAL IMPLICATIONS:
The SWM Redevelopment/Infill fee (Cash-in-Lieu) is being deposited into account 57500075
WTBI-SWM CERTIFICATION-DEPOSIT.
$202,490 in SWM fee contributions have been collected in 2010 (as of October 31,
2010*) from 13 development locations, with a combined site area of 4.51 ha.
The balance on October 31, 2010* was $147,401.
* The reporting cycle for the 2010 SWM Audit is November 1, 2009 to October 31, 2010.
The available funding is to be used for installation of two OGS units (as part of the 2011 road
reconstruction work) and for the completion of new ponds, retrofit ponds, and stream
rehabilitation works as identified on the priority list.
COMMUNICATIONS:
Copies of the final documents have been forwarded to members of the Steering Committee
(City of Kitchener, GRCA and the Region of Waterloo). A final copy of the report is available for
review in the Council Office.
ë ó í
CONCLUSION:
2010 was the 9th year that the City's Master Stormwater Management Policy has been in effect.
The results from the 2010 SWM Audit are summarized in the attached Executive Summary.

Executive Summary
INTRODUCTION
As part of the recommendations of the 2001 Stormwater Management (SWM) Report, an annual audit report is
prepared to summarize the work that has been carried out as related to the Citywide Plan and summarize the status
of in-stream water quality conditions from the monitoring program. In 2002 the first annual audit report was
completed. The 2010 annual audit will be the ninth report submitted.
The purpose of the annual audit report is to indicate whether or not the SWM measures provide for the necessary
water quantity control and water quality treatment of stormwater resulting from infill/redevelopment sites. The review
is to be completed in conjunction with a review of the capital budget and an assessment of the following years
budget. The review lists the catchment area provided by the facilities built and the corresponding area contributed by
the redevelopment and infill locations. The priority/implementation order for SWM facilities and stream rehabilitation
has been reviewed at this time and modified as appropriate based on the location of redevelopment/infill, monitoring
data and the location of SWM measures implemented. This audit report is also intended to review the
implementation strategy and recommend any changes/additions to the priority lists.

SUMMARY OF STORMWATER MANAGEMENT PLAN ANNUAL AUDIT - 2010
Balance of C-i-L Fee Contributions and Refunds Completed in 2010
$202,490 in SWM fee contributions have been collected in 2010 (as of October 31, 2010) from 13
development locations, with a combined site area of 4.5 ha.
Stream Restoration
Victoria Lake EA, Environmental Assessment was completed in 2009, detailed design and
implementation of the preferred alternative is anticipated to began in late 2011 or early 2012.
Retrofit Facilities
No works completed in 2010 were funded by cash-in-lieu contributions. However, in 2010 as part of the Federal
Government Infrastructure Stimulus Spending retrofits were designed and constructed for SWM Facilities 4 and 22.
These facilities were identified in the 2001 Stormwater Management (SWM) Report as potential retrofit opportunities.
Both facilities were originally designed as dry facilities and have been retrofit to meet Ministry of Environment SWM
guidelines (MOE, 2003) providing enhanced (Level 1) water quality control. Pond 4 is designed as a wet pond and
Pond 22 as a hybrid wet pond/wetland.
In addition, a dam removal was undertaken at the Wards and Brigadoon Pond in the Strasburg Creek sub-
watershed.
New SWM Facilities
No new SWM facilities were completed by the City and no work initiated by the City on new SWM facilities for the
2010 audit year. However, new SWM ponds accounted for in previous audit years which were constructed and
.
initially accepted by the City in 2010 are shown in Error! Reference source not found.The City is responsible for
maintenance of these ponds however, final assumption will not occur until after 90% of catchment is built and
stabilized, the pond has been cleaned out, engineering, operations and parks staff have completed inspections, and
a topographic survey confirms berm and pond bottom elevations. Ponds, accounted for in previous audit years
.
which received final acceptance by the City are shown in Error! Reference source not found.

Table 3.11: Kitchener Water Quality Monitoring Results –2010 Summary
Parameter 2010 Summary
Chloride Overall, dry weather samples showed higher chloride concentrations. Sandrock Greenway (SR2) showed the highest levels for
both dry and wet weather samples, with a max dry weather value of 472 mg/L. Stations located on Sandrock Greenway (SR2),
Montgomery Creek (MG1) and Strasburg Creek (SB13) had average dry weather sampling results that exceeded the proposed
SWM guideline of 250mg/L. All stations had dry weather samples that exceeded the proposed SWM guideline of 250mg/L.
E. coli All wet and dry E.Coli samples in 2010, were above the Recreational Waters Guideline of 100CFU/mL with the exception of one
dry event at each Kolb Creek (KD1) and Schneider Creek and numerous wet and dry samples at Blair Creek (BBB11 and BL1)
and Roseville Tributary (BL1 Trib.) All the wet weather results were above the Kitchener SWM Guideline of 1200CFU/100mL.
Sandrock Greenway (SR2) and Shoemaker Creek (SM1) showed dry weather average results to exceed the Kitchener SWM
Guideline of 1200CFU/100mL. Sampling averages for all stations were above the Kitchener SWM Guideline.
Nitrate The water quality guideline for nitrate (CCME) of 2.9 mg/L was exceeded in both dry and wet weather samples at Kolb Creek
(KD1), Idlewood Creek (IW3), Blair Creek (BL1) and Roseville Tributary (BL1 Trib.) and for only dry weather at Montgomery
Creek (MG1). Average nitrate concentrations were similar to trends noted in past years, with the exception of Kolb Creek (KD1),
showing higher average dry weather results in the past two years. Montgomery Creek (MG1), Idlewood Creek (IW3), Roseville
Tributary (BL1Trib) and Blair Creek (BL1) and have average dry weather nitrate concentrations greater than the CCME
guideline.
MetalsAll average wet weather sample values of copper were greater than the PWQO limit of 0.05mg/L, with the exception of Kolb
Creek (KD1) and all stations within the Blair Creek watershed (BL1, BBB11, BL1Trib). Both Idlewood Creek (IW3) and
Sandrock Greenway (SR2) had average dry weather samples exceeding the PWQO. Henry Strum (HS1), Montgomery Creek
(MG1) and Shoemaker Greenway (SM1) yielded average lead concentrations above the upper PWQO limit of 0.025mg/L. For
zinc samples Henry Strum (HS1), Strasburg Creek (SB13) and Idlewood Creek (IW3) showed individual samples much higher in
comparison to other values. Overall both wet and dry average values for all sampling stations exceeded the PWQO of
0.03mg/L.
Total Total Phosphorus often exceeds the Provincial Water Quality Objective (PWQO) of 0.03 mg/L, especially in wet weather. All
Phosphorus 2010 wet weather average concentrations of total phosphorus were above the PWQO limit. For dissolved phosphorus, there is
an overall trend of increasing concentrations for both dry and wet average concentrations at the majority of the stations.
TSS (Total All of the average wet weather samples exceeded the CCME guideline of 25mg/L, with the exception of Blair Creek (BBB11 and
SuspendedBL1), Laurel Creek (LC1) and Schneider Creek (SC1), while the dry weather samples tended to fall below the CCME guideline.
Solids) Henry Strum (HS1) and Shoemaker Greenway (SM1) had the highest average results for TSS in 2010. The annual averages for
the core stations were consistent with historical results.
Overall in 2010 Sandrock Greenway, Strasburg Creek (North Branch), Henry Strum Greenway and Shoemaker
Creek exceeded guidelines more frequently than other creeks sampled.
The following points summarize results of the 2010 biological monitoring of seven stream stations present within the
City of Kitchener.
1. Biological sampling in 2010 occurred early in the growing season following a Winter with little snowfall. The
low stream flows present during the sampling dates may have resulted in lower numbers of fish present than
certain previous sampling years
2. The Hilsenhoff Biotic Index (HBI) values were very similar to previous years. This result provides assurance
that the method being used is robust and provides an accurate indication of water quality at the sampling
sites.
3. The numbers of fish species captured during the 7 station survey in 2010 were comparable to or slightly
lower than some previous years.

4. The 2010 water chemistry analyses confirm what the biological results indicate, that is, that stormwater
runoff substantially affects water quality in all of the streams sampled in 2010.
Sampling at two stations, sampled previously only during 2002 and 2008 has yielded valuable comparative
monitoring data.
2011-2015 Proposed Monitoring Program
It is the intent of the 2011 program to build upon data collected in 2002-2010 and ensure data collected in the next
five (5) years will be useful to produce the third Kitchener Stormwater Report Card. This recommendation includes
annual monitoring of core stations (Henry Sturm Greenway (HS1),Kolb Creek (KD1), Montgomery Creek (MG1)) an
additional monitoring year to be included at Sandrock (SR2), and Strasburg Creek (SB13) to provide sufficient data
for trend analysis. Additional sampling at stations at Idlewood Creek (IW3) and Showmaker Creek (SM1) has been
recommended in order to provide sampling results to be used in the stream restoration prioritization process, and
ensure all major creeks are included in the monitoring program.
The 2011 program will include five (5) wet and five (5) dry weather samples and will include the following
parameters:
Chloride;
E.coli;
Nitrate;
Copper;
Lead;
Zinc;
Total and Dissolved Phosphorus;
Total Suspended Solids (TSS); and
Hardness (as CaCO).

Evaluation of SWM and Stream Rehabilitation Targets
The evaluation of area serviced for SWM retrofit/OGS installation should exceed the development area for infill and
re-development on a yearly basis. It should be noted that in many cases, projects span several years, but can only
be included in a single year’s assessment. Since projects often have several phases (environmental assessment,
design and construction) it is important not to double-count the drainage area serviced. Due to the nature of these
Tables 2.5Table 2.6
projects, a cumulative comparison provides a better evaluation of the program. and provide a
summary of the program between 2002 and 2010. Between 2002 and 2010 the area being serviced for SWM
retrofit/OGS installations funded by C-i-L contributions was 154.12 ha. This compares to the cash-in-lieu drainage
area of 116.13 ha. SWM retrofit/OGS works should continue to be implemented to ensure cash-in-lieu payments are
being matched by water quality control coverage.

2009 Recommendations
Implementation
1. Further investigation of sensitive areas should be completed to assess the potential for vulnerable area
designation that would require reduced road salt application.
Action: The City of Kitchener currently practices Best Management Practices to ensure road salt
application does not exceed necessary levels while maintaining a level of service.
2. Re-evaluation of the identification and prioritization process of storm ponds and OGS units. This should
include investigation of prioritization based on a subwatershed basis and should be completed prior to
further facility retrofits and implementation as per the Canadian Environmental Protection Act, 1999.
Action: This item will be included in the 2011 Stormwater Audit.
3. Cash-in-lieu fee may be increased as per land cost analysis but should not go above that which would deter
the implementation of policy objectives regarding preference for regional SWM facilities and reduced
privately owned onsite controls.
Action: The C-i-L fee remained as $24,845 in 2010 and increased to $31,056/ha effective March 2011.
Monitoring
4. Continue to recommend to the GRCA and RMOW, to include all parameters included in the Stormwater
Monitoring program for sampling programs within the City of Kitchener.
Action: GRCA included all sampling parameters in 2010 monitoring programs within the City of
Kitchener
5. Future monitoring initiatives should implement 10 core monitoring stations with 5 wet and 5 dry event
samples per year to provide and assess historical trends.
Action: 2010 Audit Report includes recommended sampling program for 2011-2015. This includes nine
monitoring stations with each sampling year to include collection of 5 wet and 5 dry samples at seven of
the nine stations.
6. High nitrate levels at KD1 and MG1 should be further investigated through land use assessments and
monitoring well data (if available through the ROW).
Action: Complete based on information and data available to date.
2010 Recommendations
Implementation
1. OGS and associated drainage area files are to be updated to provide for identification of City owned OGS
units. This information will be incorporated into the ‘treated area’ analysis included in the 5-Year Report.
2. Re-evaluation of the identification and prioritization process of storm ponds and OGS units. This should
include investigation of prioritization based on a subwatershed basis and should be completed prior to
further facility retrofits and implementation.

3. Preliminary Trend Analysis – Parameters with more than eight (8) years of data should be analysed to
provide an indication of increasing trends by site location and parameter. This preliminary analysis should
be completed to reduce the risk of identifying false trends.
4. Other analysis potentially including upstream land use, impervious characterization should be complete to
identify variables and trends.
5. Stream walk assessments should be completed every five (5) years with the next to be schedule for 2014-
2015.
6. The dry weather outfall program should be re-evaluated.
