STORMWATER MANAGEMENT FEATURES
INSPECTION, RECORD MANAGEMENT BEST

Overview of Stormwater Management in the
Lake Simcoe Watershed
 Stormwater Management (SWM)
facilities and oil/grit separators most
common SWM practices
 Urban stormwater contributes 31% of
phosphorus loading to Lake Simcoe –
contributes to lake eutrophication
 Improved SWM works operation and maintenance contributes to
reduction in phosphorus loadings:
•
•
Ensures SWM facility performance is sustained
May minimize conditions that contribute to re-suspension of total
phosphorus into the permanent pool
Project Overview, Best Published
Practices, and Current Practice Practices
• Project Objective: improve the capacity of
municipalities to adopt best practices for SWM works
inspection; operation, monitoring and maintenance
(OM&M); and associated record management.
• Best Published Practices
• SWM Facilities Inspection, Operation and Maintenance
Guidance (TRCA, June 2016)
• Low Impact Development Inspection, Operation and
Maintenance Guidance (TRCA, June 2016)
• Current Practice Review
• Summary of Findings
• Deviation from Best Published Practices
• Barrier to Adoption of Best Practices
Current Practice Review – Summary of Finding
SWM Works Inspection and Operation/Maintenance
Complete Major Repairs.
Complete Minor Repairs.
Have sufficient training to complete
quality inspections.
Have comprehensive inspection
forms.
SWM works inspection, O&M system
in place (complete inspections).
Current Practice Review – Summary of Finding
Recordkeeping Practices
• Most municipalities:
• Have electronic or hardcopy filing of
documents with a range of adequacy
• Have daily logbooks
• Do not have a GIS system and/or have a
GIS system but only store SWM land
parcel information
• Wish to use GIS for SWM works
inspection, O&M record management
• Few municipalities:
• Store work orders with inspection forms
for operation and maintenance work

Data Model Needs Assessment
• Data model – “a description of the rules by which
data is defined, organized, queried, and updated
within a database.”
• Take what we’ve learned and incorporate into the
filing cabinet (aka Data Model) you want to build

Conclusions and Recommendations
• Current Practice Review
• SWM feature inspections
• Comprehensiveness
• Frequency
• Training/education of staff varies significantly
• Repairs
• Minor repairs completed
• Major repairs not completed (financial / staffing constraints)
• Electronic / hard copy of SWM feature documentation
(OM&M)
• Not entered into GIS
Conclusions and Recommendations Continued
• Current Practice Review continued
• Barriers to adoption of best practices

Staff resources
Lack of council support
Lack of communication regarding education and awareness
• Alternatives / Solutions to overcome barriers
asset management
training and education for staff
educate council
use of summer students as possible
stormwater utility fees
recognize SWM/LID facilities are complex features
record management in GIS
experts should provide their expertise as required
documentation accessibility
alternatives required to improve feature accessibility
Conclusions and Recommendations Continued
• Data Model Needs Assessment
• Municipalities want a more efficient method to respond
to information requests
• Want to store data in a common digital GIS format that
will analyze, predict trends, and disseminate
information quickly
• Hyperlinking to Windows Explorer folders is critical
• Imperative to prepare for future modelling and data
needs
Conclusions and Recommendations Continued
• Data Model Development
• Collection of data divided into phases
• Phase 1 – mandatory and optional
• Phase 2 – detailed facility information
• Phase 3 – contributing pipe/storm network data
• Provides common data capture standards
• What data to collect
• How often to obtain and update
• How to collect the data within a GIS format
• December 2018 to implement
• Future: to be championed by York Region and LSRCA
Implementation of Data Model
• Work Plan
• Create data model shell containing mandatory, optional,
and organization mandated files (datasets/attributes) in
GIS as (a) shapefile(s) or as a geodatabase
• Gather required data for mandatory files
(datasets/attributes) for each SWM/LID facility managed
within jurisdiction. Information for optional files could be
gathered at the same time, resources permitting
• Populate into GIS shapefile(s) or geodatabase as
information becomes available
• Have appropriate O&M/engineering staff QA/QC data
entered into GIS
Implementation of Data Model Con’t
• Municipality Responsibilities
• Building and populating the data model
• Senior management to obtain necessary approvals for
staff time (and associated budget) and champion
initiative
• SWM staff (as ‘subject matter experts’) to project
manage the work plan and mobilize the necessary O&M,
Engineering, and GIS staff to assist with gathering
required files (data mining)
• Use co-op/summer students as necessary/available to
assist with gathering required files (data mining) and GIS
data entry into filing cabinet (data model)
• Ongoing maintenance of data model
Implementation of Data Model Con’t
• Potential MOECC / LSRCA support
• Engage senior management where necessary
• Provide / coordinate co-op/summer students as a
resource to assist with gathering required files (data
mining) and GIS data entry into filing cabinet (data
model)
• Request data on oil/grit separators from manufacturers
• Provision of stormwater facility inspection / data collector
tool training
Implementation of Data Model Con’t
• Timeline
• December 2018
• Allows for development of funding agreement
• Allows for development of data collection tools
• Allows for developing a communication plan and discussing
with municipalities, as necessary
• Allow for budgeting (staff/time/resources) including the
assistance of summer/co-op students, if feasible
• Milestone goals:
•
•
•
Stormwater inspection and data entry training: May 2018
Three to four “data-ready” municipalities completed: June
2018
Seven to eight “data not ready” municipalities completed:
December 2018
Final Thoughts
• SWM works best published practices will
remain an aspirational target
• Best practices dictate a level of expectation that
is simply unachievable at the present time
• Unanimous agreement from all stakeholders
that numerous opportunities exist for
municipalities to continue to work towards
‘better practices’ for all SWM and LID facilities
within their jurisdiction
