Name of Community: Elk Point/Zephyr Heights/Round Hill
Date: July, 2004
Project Title: Elk Point/Zephyr Heights/Round Hill Unit 4 - Thinning and Brush Removal
Vegetative Fuel and Topography: Second growth stand of Jeffrey pine with some white fir, incense cedar, and a brush understory, located along the eastern edge of the Round Hill residential area. A fire in this area could extend into the residential area. Slopes in the unit vary from 5-60%.
Worst Case Scenario / Hazard: An ignition from the highway or below on a high hazard day with high winds off the Lake would be pushed by wind and topography into the residential community.
Because most fuels are not below and on the windward side of the community, this project ranks as #9 for the TDFPD.
South and West of the Round Hill neighborhood. See Figure 11-7.
Remove or thin brush understory to decrease fire intensity and reduce ladder fuels. Spacing between remaining bushes should be 2-3 times the height of brush. A brush masticator or “Bull Hog” could be used where slopes are 30% or less. Grind the brush and leave as mulch, or hand cut, pile, and burn. Use of herbicide could reduce sprouting of some species. Thin from below, removing smaller trees and leaving larger ones to achieve the desired stocking rate of 80 to 100 square feet of basal area per acre.
*Prescribed fire could be used to reduce the brush understory, and desired where feasible to return fire to the landscape. It should only be applied in areas after thinning and slash pile burning are complete to maintain fire control.
Treatment in this area will help contain human-caused ignitions in the residential area near the project area, keeping fire from spreading uphill and becoming uncontrollable. It will also protect the private and commercial structures from a downslope fire event. Implementation of the prescription will reduce the competition among residual trees, increasing forest health and decreasing tree mortality. This will reduce the amount of accumulated dead and down material contributing to the fuel loadings on the forest floor and reduce the chance of a ground fire becoming a crown fire. The prescription will also increase the chance of a crown fire in untreated areas (eastside) dropping to the ground and becoming easier to control.
If all of the recommendations in this report are implemented, there is still no guarantee that a devastating wildfire will not occur in the area. However, community awareness and individual attention to fuels management on private property and fuel reduction on state, federal, and county property will help to achieve the highest level of wildfire safety possible.
Environmental compliance measures must be implemented before project initiation. Stream Environment Zones are located in the project area and must be protected, employing appropriate TRPA mitigation measures.
Some threatened and endangered species exist in the Tahoe Basin. Appropriate avoidance and mitigation measures should be employed during project implementation.
Compliance with cultural resource protection may also be necessary. Check with TRPA and the NVSHPO to ensure cultural resources are protected.
Rehabilitate any fire control lines, landings or disturbed areas. Rehabilitation will be minimal if only hand methods are used. Where soil has been disturbed, TRPA rehabilitation measures and Best Management Practices would apply. This could include reseeding or mulching areas if necessary.
May - December
Two operational seasons.
Mechanical Treatment (Slopes <30%): | $1750.00/acre for 160 acres | |
Hand cut, pile and burn (Slopes >30%): | $2000.00/ acre for 125 acres | |
Prescribed fire: | $2,000/acre (USFS) for 285 acres | |
Total Cost | $1,100,000 |
Biomass to be removed is approximately 32 tons/acre
Conduct a prescribed fire within five years after treatment by hand cutting, piling and burning area. Re-treat with prescribed fire every ten years to control the growth of brush and small trees in the understory.
