Relative Effectiveness: No interviewee rated this <br />treatment. <br />Environmental/Implementation Factors: Large <br />riprap is placed upstream and downstream of actual <br />road crossing area. Armoried crossings are often used <br />for ]ow traffic volume roads. Low water crossing were <br />not used on one fire because they could attract an <br />endangeredtoadspecieathatwouldinhabitthecroas- <br />ing when wet and be killed by vehicle traffic. <br />Outalouine <br />Purpose. Outaloping prevents concentration of flow <br />on road surfaces that produces rilling, gullying, and <br />rutting. <br />RelatrveEtfectrveness Not enough interviewees rated <br />this treatment. <br />One interviewee commented that this is one of the few <br />treatments that has both immediate and long-term <br />facility and resource benefits. <br />Environmental/Implementation Factors Sometimes <br />after regrading, compaction dcea not occur due to low <br />traffic volume which may cause sheet and rill erosion. <br />Both public and administrative traffic should be cur- <br />tailed during wet road conditions to prevent rutting <br />and road sub-grade damages. <br />Trail Work <br />Purpose. BAER treatments on traffa are designed to <br />provide adequate drainage and stability so trails re- <br />main functioning. <br />Relatrve Effectveness. Not enough interviewees rated <br />this treatment to make any statements about its <br />effectiveness. <br />Envrnmental/Implementation Factors Crew skill <br />is important for this Labor intensive treatment. Water <br />bare need to be installed correctly, proper slope and <br />depth, to be effective. <br />Other Treatments <br />Purpose: This category consists of various treatment <br />solutions to specific problems. It includes wetting <br />agents to reduce water repellency on high erosion <br />hazard areas, gully plugs to prevent headcutting in <br />meadows, flood signing installation to warn residents <br />and visitors of flooding potential, and removal of loose <br />rocks above roadways that were held in place by mote, <br />forest debris, duff and were now in a precarious posi- <br />tion due to the fire. <br />Relatrve Effectrveness No interviewees rated these <br />treatments. <br />Environmental/Implementatron Factors Treatment <br />specific. <br />USDA Forest Service Gen. Tech. Rep. RMRS-GTRE3.2000 85 <br />
