DATE OF REPORT: September 3, 2015
REPORT NO.: INS-15-076
SUBJECT: Stormwater Management Master Plan Status Update
RECOMMENDATION:
For information.
BACKGROUND:
In 2014, City of Kitchener staff along with a consultant team completed a review of the
Stormwater Management Policy 1-1135 and recommended to Council (see INS 14-037) that an
Integrated Stormwater Management Master Plan (ISWM-MP) be developed to replace the 2001
policy to meet the following goals:
• Comply with legislated changes and forecast policy direction — next 15 years,
• Establish proactive O&M programming,
• Align work plan with current funding strategy,
• Coordinate with other initiatives i.e. Multi-Use Pathways and Trails Master Plan,
• Enhance public participation in Credit Policy,
• Create new design standards for new and redevelopments across the City, and
• Demonstrate accountability and transparency in the approach we take.
An ISWM-MP will serve as a decision support tool, a methodology for the prioritization of works,
a means to estimate future SWM requirements and costs and a transparent community process
by which the City can establish stormwater management guidelines and policies for the next 15
years.
REPORT:
In order to meet the stated goals of the study, a series of tasks were identified. This report is to
provide a brief summary of the status for each of the study tasks.

• Task 1 — Characterization
• Background Review, policy, environment and infrastructure
• Watershed Condition - 20 watersheds
• Confirm Study Goals and Objectives
This task is essentially complete with the exception of missing bathymetric survey information of
all stormwater ponds which is used to assess how much sediment has accumulated in each
pond. This will help to inform a proactive maintenance approach and a prioritized list of ponds to
be cleaned out. This information is expected in the month of September.
A draft 315 page long Existing Conditions report can be found here:

• Task 2—SWM SYSTEM ANALYSIS
• City Wide Trunk (InfoSWMM) Model
• Climate Change Scenarios (InfoSWMM)
• Stream Erosion Assessment
• Open Space System
• Infill and Redevelopment (InfoSWMM)
This task is ongoing. The city wide trunk model for the existing conditions is 98% complete. Staff
are currently working with the Region of Waterloo to locate missing pipe information which is
required to run the model. Once the model is functional it will be run to assess sewer capacity
for all Priority A areas identified in the Kitchener Growth Management Strategy. In addition to
assessing growth and development scenarios, the model will also be run to assess climate
change scenarios with more intense and frequent storms than what has been seen historically.
This will help to define how resilient the community is to climate change as well as identify areas
of the City where resources should be focused to mitigate climate change impacts into the
future.
The stream erosion assessment field work has been completed. Our consultant is currently in
the process of reviewing and processing the field data in order to identify and prioritize active
erosion sites as well as less severe sites that require preventative maintenance so that they
don't become active erosion sites.
• Task 3— EVALUATE ALTERNATIVES
• Develop Long List & evaluate
• Retrofit Scenarios (existing development)
• GI (Green Infrastructure) and Ponds, Streams
• Market Based Approaches, SWM Credit Policy Enhancements
A long list of alternatives has been identified and was presented at the first Public Information
Center on June 24, 2015 (the PIC boards can viewed on the website referenced earlier).
Various retrofit scenarios are currently being considered for road, stream, pond and municipal
facility projects. Evaluation criteria for these scenarios are also in development and are currently
scheduled to be discussed at the next Project Team meeting on September 30, 2015. Also on
the agenda for that meeting is a discussion around the Market Transformation Strategy,
enhancements to the stormwater credit policy and how these items interact with the existing
cash-in-lieu approach for new developments prescribed by the existing 2001 Stormwater
IF1 - 2
Management Policy. These discussions will be taking place over the months of September to
December.
• Task 4—SELECT PREFERRED STRATEGY
This is anticipated in December/January.
• Task 5— IMPLEMENTATION PLAN
This is anticipated in February/March.
ALIGNMENT WITH CITY OF KITCHENER STRATEGIC PLAN:
The development of ISWM-MP aligns to the following areas of the City's current strategic plan:
• Sustainable Environment and Infrastructure, and
• Effective and Efficient City Services.
FINANCIAL IMPLICATIONS:
Not applicable at this time. Financial implications will be discussed as part of the study
recommendations in February/March and will inform the 2017 budget cycle.
COMMUNITY ENGAGEMENT:
Extensive efforts have been undertaken to engage the community in this process including:
• Establishment of a Cyber-Public Advisory Committee which includes various community
stakeholders and organizations,
• Consultation with the Environmental Committee,
• Information booths at City events,
• Newspaper ads and articles,
• Public Information Centers,
• Online survey,
• Bill inserts,
• Etc.
