Comprehensive Stormwater Management Master Plan-Project Description

The Township of King’s Comprehensive Stormwater Management Master Plan is a model for balancing development and ecological preservation. This case study highlights how Civica Infrastructure Inc., a leader in water resource management, addressed complex challenges to create a sustainable future.

Project Description

In 2018, Civica embarked on a mission to develop a Comprehensive Stormwater Management Master Plan (CSWM-MP) for the Township of King.

Guided by the standards of both the Toronto and Region Conservation Authority (TRCA) and the Lake Simcoe Region Conservation Authority (LSRCA), this initiative aimed to harmonize urban development with nature’s demands.

The project was executed according to the Municipal Class Environmental Assessment (EA) Phases 1 and 2, ensuring a thorough evaluation of the Township’s stormwater infrastructure.

Civica assessed various parameters, including hydrology, geomorphology, and natural heritage, dividing the study area into distinct management units. Through sophisticated models simulating stormwater dynamics, we aimed to ensure quality, quantity, and erosion control.

The Municipal EA process began with a problem statement outlining existing stormwater drainage system deficiencies and their environmental impact. Civica implemented a plan, suggesting improvements to current facilities like stormwater management pond retrofits and future development mitigation like LIDs.

Additionally, the project involved organizing the Township’s stormwater management inventory in a database for future maintenance planning.

Civica conducted topographic surveys and component inspections for 10 Township-owned SWM facilities. The project aimed to gather missing design information for these facilities to establish a storage-discharge relationship and develop a hydrologic model.

Condition assessments were also carried out to evaluate the facility’s components, including access roads, inlets and outlets, emergency spillways, and overall functionality.

Relevance of Experience

Civica’s stormwater management expertise was key to the Township of King’s master plan. Relevant specialties included:

  • Following the Municipal EA process for thorough analysis
  • Hydraulic and hydrologic analysis
  • Stormwater facility inspection
  • Evaluation of stormwater levy alternatives
  • Virtual public consultations for transparency and community engagement.

Challenges Faced

The project was not without its hurdles. One significant challenge was the incomplete background information on several stormwater management facilities. This necessitated a careful topographic survey and component inspections to fill gaps, such as permanent pool elevations and storage volumes.

In addition, georeferencing and photo documentation were employed to ensure a detailed record of each site’s condition. The intricate process of integrating this data into a cohesive hydrologic model required precision and adaptability, underscoring Civica’s capability to overcome complexities in stormwater management.

Lessons Learned

The Township of King’s master plan illuminated several critical insights for future projects.

  • Thorough data collection and analysis are crucial for effective planning and resource allocation of stormwater systems.
  • Virtual consultations with the public foster community ownership and support.
  • Continuous innovation in stormwater solutions is needed, including integrating Low Impact Development (LID) techniques to mitigate future impacts.
