Variances

• 1. Single-Family House Height - measured from FCL
• 2. Coach House Height - measured from FCL
• 3. Coach House Front Yard Setback - from 9.1m to 2m
• 4. Highest Building Face Envelope - measured from FCL
• 5. Basement Definition – floor area excluded due to higher FCL grade
• 6. Retaining Walls - measured from FCL, not higher than 1.22m

Policy and FCL Considerations

OCP:

• The OCP recognizes that climate change impacts, such as sea level rise

and more frequent extreme weather events, are occurring around the world.

• OCP identifies numerous directions to enable the District to remain, and

become more resilient from social, economic, housing, transportation, and environmental perspectives.

• 2.6.20 - Employ land use regulations, non-structural enhancements and

structural flood protection measures to reduce potential impacts on public safety and property from sea level rise and storm surge.

FCL Considerations:

• Section 524 of the Local Government Act, authorizes the District to

designate floodplain land – currently West Vancouver does not have land specifically designated.

• Staff are currently developing policy and regulations to mitigate the risk of

flood impacts.

• In the absence of a designated FCL by-law and guidelines staff can request

information from a certified professional specifying how sites can be safely used (based on the authority of the Chief Building Official).

Mitigation Measures

• Retain existing foreshore protection wall
• Secondary flood protection wall incorporated into landscaping
• Pervious landscaping in foreshore area
• Improved site drainage
• Raised grade to attain FCL
• Flood proof basements

Conclusion

• Consistent with the OCP to create safer and more resilient sites and to

reduce potential impacts on property from sea level rise and storm surge.

• The proposed variances are required to develop the site safely based
• n the FCL determined by a coastal engineer;
• Little to no windows on west elevation to maintain privacy;
• Successful tree retention in the boulevard and hedgerow east of the site

provide a robust buffer; and

• Minimal correspondence received by adjacent neighbours (to date).
