1. POLICY PURPOSE:
Concise, easy-to-understand statement, which explains the objective or philosophy underpinning the policy.
This policy serves as a decision support tool as well as a methodology for the prioritization of
works outlined in the Integrated Stormwater Management Master Plan (ISWM-MP).
2. DEFINITIONS:
Unusual or specialized language, acronym, jargon or unique application of words.
“Stormwater” - refers to rainwater and melted snow that flows over roads, parking lots,
lawn and other sites in rural and urban areas.
“Stormwater Management” - refers to practices which help to minimize the impact of
polluted runoff flowing into watercourses, control the rate at which, or prevent, flooding
from occurring and reduces the strain that stormwater places on municipal infrastructure.
“Low Impact Development” - is an innovative stormwater management approach with a
basic principle that is modeled after nature: manage rainfall at the source using uniformly
distributed decentralized micro-scale controls.
3. SCOPE:
Statement as to whom the policy applies, as well as exceptions and the ramifications of non-compliance, if any and
deemed appropriate to include.

POLICY APPLIES TO THE FOLLOWING:
All Employees
This policy applies to all staff involved in any form of decision making related to any
form of construction on municipal and private land. This includes but is not limited to:
Engineering
Facilities Management
Operations – Roads and Traffic
Operations – Environmental Services
Transportation Services
Building
Planning
Economic Development
4. POLICY CONTENT:
Policy details, including specific roles and responsibilities relating to the policy.
A.Stormwater Infiltration in the Context of Source Protection Planning
This component defines where and how infiltration based stormwater management controls,
commonly referred to as Low Impact Development (LID) controls, can safely be planned and
constructed in the context of the approved source protection planning policy under the Clean
Water Act.
Developed in consultation with the Region of Waterloo staff and the Ministry Of Environment
and Climate Change, this component of the policy acknowledges that the use of infiltration
practices to reduce runoff and restore natural hydrologic processes is crucial to maintaining and
improving the City of Kitchener’s natural water systems, maintaining the viability of local
stormwater infrastructure, and contributing to climate change adaptation & mitigation strategies.
As the implementation of infiltration practices becomes more prevalent, the City of Kitchener
has a duty to protect local groundwater resources by implementing a land use-based stormwater
infiltration framework which is developed based on a sound understanding of identified and
future risks.
Sites with high risk activities are generally discouraged from incorporating LID techniques that
utilize infiltration as its primary function for sensitive drainage areas and require the proponent
to prepare a Pollution Prevention Plan and/or Risk Management Plans as part of SWM Reporting
requirements. Spill prevention and management are a central focus of such plans.
Also identified within the Implementation Plan are the infiltration opportunities and constraints
and lists of acceptable practices within various land-uses ranging from Residential, Mixed Use,
Commercial, Industrial Employment, Institutional and Open Space and Natural Heritage
Conservation as well as local, minor and major roadways within the City of Kitchener.
B.Stormwater Volume Criteria and Targets
This component outlines the minimum stormwater volume criteria as well as outlines the
application of general stormwater management targets as part of:
16 of 18
2 - 16
New development,
Redevelopment, reurbanization and residential intensification, and
Linear projects (roadways, trails and transit infrastructure etc.).
As part of this component, all sites within the City of Kitchener are required to:
Continue to control off-site runoff for flood control and erosion per the approved
watershed, subwatershed, master drainage plans, Environmental Impact Statement (EIS),
Provincial Policy and Guidelines or other area specific studies. Special Policy Areas which
address known or flood prone areas would remain in effect.
Continue to achieve infiltration targets to maintain the existing water balance per current
approved and future subwatershed plans. The Development Engineering section will identify
relevant subwatershed plans and policies.
Control for water quality (pollutant loadings) in accordance with current MOECC
guidelines to ‘Enhanced-Level 1’ protection as defined in the 2003 Stormwater Management
Planning & Design Manual.
Retain a minimum of 12.5mm of runoff from the all surfaces on the entire site and to enroll
in the City of Kitchener Stormwater Utility Credit program. Retention can be a combination
of infiltration, evapotranspiration or rain water re-use (also known as rainwater harvesting).
All volume retained on-site will be counted towards achieving flood and erosion control,
water quality control as well as credits toward existing infiltration targets.
In all cases, the targets as specified in this component shall be superseded by more stringent
targets as developed by the MOECC or through future Watershed Studies, Subwatershed Studies,
Master Drainage Plans, Environmental Impact Statement (EIS) and/or other area specific studies
such as GRCA Wetland Policy.
C.Stormwater Management Fee
A Stormwater Management Fee (formerly Cash-in-lieu) has been established such that a
development proponent shall provide a designated financial contribution at the current per
hectare rate as defined by the City of Kitchener, as amended from time to time where the
requirements of the Stormwater Infiltration in the Context of Source Protection Planning
and the Stormwater Targets and Volume Criteria are not be fully achieved. This fee will be
applied towards off-site stormwater management elsewhere in the city, in conformance with the
recommended approaches of the Integrated Stormwater Management Master Plan (ISWM-MP).
Funds will be collected by the City of Kitchener SWM Utility until such time as a suitable
project or program is identified for partial or full funding.
Sites with Restrictions
For all sites regardless of perceived constraints, the proponent shall be required to fully comply
with the appropriate volume control targets described above. Should pre-consultation with City
of Kitchener engineering staff and/or pre-design investigation by the proponent and reviewed by
the City Engineer identify that volume targets are not achievable; the proponent must consider
and present the merits of relocating project elements to address varying soil conditions and other
17 of 18

constraints. Site constraints which may result in the City permitting alternatives to the above
prescribed volume targets are based on:
i.Shallow bedrock,
ii.High groundwater,
iii.Contaminated soils (i.e. Brownfields)
iv.High Risk Site Activities
v.Prohibitions: Issue Contributing Areas (ICA) and or WHPAs with a vulnerability
score equal to or greater than 8
vi.Restrictions: including WHPAs with a vulnerability score of 2 to 6 inclusive
On sites where the proponent cannot implement the required volume control to the Maximum
Extent Possible or MEP as confirmed by the City of Kitchener Development Engineering, the
site is required to contribute to the Stormwater Management Fee at the current per hectare rate as
amended from time to time.
5. HISTORY OF POLICY CHANGES
There are two types of policy updates. 1) “Administrative Updates” are done to reflect the current corporate structure and
job titling and do not need Council or CLT approval. 2) “Formal Amendments” are major changes to the intent and
purpose of the policy and require Council or Corporate Leadership Team (CLT) approval.
Administrative Updates
The date (yyyy-mm-dd) and a short annotation on the nature of the change to reflect the current corporate structure i.e.
Departmental re-organization / Titling changes / Standing Committee restructuring.
Formal Amendments
The date of the resolution passed by Council or CLT, for example, “2020-01-20 - As per Council/CLT resolution”
