REQUEST SQUAMISH FEASIBILITY AUDIT →1. IFHMP 4.59m Flood Construction Level (FCL) Compliance
Per the District of Squamish Integrated Flood Hazard Management Plan (IFHMP 2017), new construction in floodplain zones must adhere to strict structural elevations:
- Designated Flood Elevation (4.59m): Elevating all habitable living spaces, structural floor framing, and mechanical heating systems above the 4.59m geodetic elevation line.
- Elevated Backfill Pads & Stults: Engineering engineered gravel compaction pads or flood-resilient concrete crawlspaces with hydrostatic relief ports.
- Sanitary Backflow Prevention: Mandatory dual backflow valves and sealed sewer connections protecting against high river surge events.
2. DPA 1 RAPR 30m SPEA Riparian Stream Protection
Squamish’s rich river networks require Qualified Environmental Professional (QEP) stream assessments under provincial RAPR guidelines:
- Streamside Protection (SPEA) Setbacks: 15m to 30m top-of-bank protected setbacks established by certified QEP biologists.
- Ditch Classification Color Codes: Managing setback compliance: Red (10m setback), Orange (5m setback), Yellow (2m setback), Green (0m setback).
- Erosion & Sediment Control (ESC): On-site silt fencing, sediment retention basins, and turbidity monitoring during site excavation.

Addressing Squamish’s alluvial soils, high water tables, and steep granite hillside transition zones:
- High Water-Table Waterproofing: Continuous sub-slab drainage gravel beds, thick bentonite waterproofing membranes, and dual sump pump stations.
