Attachment 1 - Letter to Mayor and Council re: 14 & 14A Helmcken Road and 6 Camden Avenue
A letter from the applicant, Wayne Hopkins for HFT Ventures Ltd, describing the design considerations and features of the 'Towns on Camden' project.
Appendix 2. Generic Fuel Types (adopted from CFFDRS).
| Fuel Type | Description | Wildfire Behaviour Under High Wildfire Danger |
|---|---|---|
| Coniferous: | ||
| C1 | Terrestrial herbaceous ecosystem: mossy rock outcroppings | High potential for surface fire, especially if high moss/lichen |
| C2 | Dense regeneration to pole-sapling (immature) forest with crowns almost to ground | High potential for crown fires; low to very high fire intensity and rate of spread |
| C3 | Fully stocked, mature forest, crowns separated from ground; sparse understorey | Surface and crown fire, low to very high fire intensity and rate of spread |
| C4 | Dense, pole-sapling (immature) forest, heavy standing dead and down, dead woody fuel; continuous needle litter; continuous vertical crown fuel continuity | High potential for crown fires, high to very high fire intensity and rate of spread |
| C5 | Moderately well-stocked, mature forest, moderate dense understorey crowns well separated from ground; continuous needle litter | Low to moderately fast-spreading, low to moderate intensity surface fire |
| C6 | Fully stocked conifer plantation; absent understorey; tree crowns separated from ground; continuous needle litter | Surface fire may spread rapidly to become high intensity fire with high rate of spread |
| C7 | Open, mature coniferous stand; uneven-aged; discontinuous understorey; tree crowns mostly separated from ground | Surface, torching, rarely crowning (except on steeper slopes), moderate to high intensity and rate of spread |
| D (Deciduous) | Moderately well-stocked deciduous stands; moderate medium to tall shrubs and herb layers D-1 Leafless D-2 In leaf |
Typically a surface fire; low to moderate rate of spread and fire intensity |
| M (Mixed Forest) | Moderately well-stocked mixed stand of conifers and deciduous tree species; moderate shrub understorey; conifer crowns extend nearly to ground M-1 Leafless M-2 in Leaf |
Surface, torching and crowning; moderate to very high intensity and spread rate (varies with slope and % vegetation cover) Fine fuel % and cedar foliage retention will result in faster ignition and spread |
| S (Slash) | Slash from logging and land clearing | Rapid spreading, moderate to high intensity surface fire |
| 01-Long | Continuous standing grass – fuel loading is 0.3 kg/m2; scattered trees 01-a Matted 01-b Tall |
The taller, and more cured the grass, the more rapid spread; low to moderate intensity surface fire |
| 01-Short | Continuous human modified short grass | Typically low rate and spread and low fire intensity. |
Appendix 3. Fire Risk Classes.
Fire Risk Classes
Low (Green): The combination of the local fuel hazard, weather influences, topography, proximity to the community, fuel position in relation to fire spread patterns, and known local wildfire threat factors make it a lower potential for threatening a community. These stands will support surface fires, single tree or small groups of conifer trees could torch/ candle in extreme fire weather conditions. Fuel type spot potential is very low, low risk to any values at risk.
Moderate (Yellow): The combination of the local fuel hazard, weather influences, topography, proximity to the community, fuel position in relation to fire spread patterns and known local wildfire threat factors make it possible that a wildfire in this area would threaten the community. Areas of matted grass, slash, conifer plantations, mature conifer stands with very high crown base height, and deciduous stands with 26 to 49% conifers. These stands will support surface fires, single tree or small groups of conifer trees could torch/ candle. Rates of spread would average between 2-5 meters/ minute. Forest stands would have potential to impact values in extreme weather conditions. Fuel type spot potential is unlikely to impact values at a long distance (<400m).
High (Orange): The combination of the local fuel hazard, weather influences, topography, proximity to the community, fuel position in relation to fire spread patterns, and known local wildfire threat factors make it likely that a wildfire in this area would threaten the community. This includes stands with continuous surface/ crown fuel that will support regular torching/ candling, intermittent crown and/or continuous crown fires. Rates of spread would average 6 -10 meters/ minute. Fuel type spot potential is likely to impact values at a long distance (400 -1 000m).
Extreme (Red): The combination of the local fuel hazard, weather influences, topography, proximity to the community, fuel position in relation to fire spread patterns, and known local wildfire threat factors make it very likely that a wildfire in this area would threaten the community. Stands with continuous surface/ crown fuel and fuel characteristics that tend to support the development of intermittent or continuous crown fires. Rates of spread would average >10 meters/ minute. Fuel type spot potential is probable to impact values at a long distance (400 -1 000m or greater).These forest stands have the greater potential to produce extreme fire behaviour (long range spotting, fire whirls and other fire behaviour phenomena.
