SEWER AND COASTAL FLOOD PROTECTION MASTER PLAN

Final Recommendation Summary Report

Source Control: City Projects

• Pilot Projects to measure benefit of Downspout Disconnection, Foundation Disconnection and Low Impact Development (LID) Measures.
  • Confirm the criteria and assumptions used in the development of these solutions are valid local and that measurable reductions in inflow are observed.

• ü Updating and implementing new City by-laws:

  • City-Wide Downspout Disconnection By-Law (By-law 26-2008)

  •  Foundation Drain Disconnection By-Law

• Updating the City’s Development Standards to reflect new flood mitigation criteria.

  • Revise new sewer design criteria and mechanisms to control excess inflow.

  • Developers must demonstrate that new builds will not impact downstream areas.

  • Mandatory sewage ejector pumps for new development.

  • Develop Standards for the implementation of LIDs.

• Enhanced Educational Program

  • Homeowner and Contractor Information Sessions.

  • Develop and Distribute Education Materials and Guidelines.

  • Continue Project Website: Weatheringthestorm.ca.

• Implementing Low Impact Development (LIDs) measures, such as:

  • Exfiltration trenches (Example: Matthew Brady Construction).

  • Bioswales, Rain Gardens and Stormwater Retention Features.

  • Permeable Pavements (Example: Tranby Park Parking Lot).

• Installing rain catchers on manholes in high priority areas and eventually all manholes.

• Placement of Backflow Prevention Devices, to: ü Protect the City’s Sewer System from high river levels.

  • üProtect the City’s Sewer System from high river levels.
