In previous fire remediation work in the East Bay Firestonn (1991) and the southern California FIreS of 1993, a system which worked very effectively was for the RespollS1ble agency (RA), i.e., City ofOakland, Laguna Beach, Jefferson County, USFS, to purchase the mulch material and seed mixtures directly and pay a contractor for labor. In the BuffiIlo Creek situation, we would suggest that the USFS purchase the BFM outright, inventOIY the material at a location accessible to equipment, and monitor the daily use of and application by the contractor. Payment to the contractor would be based on the number ofloads applies. In other words, the USFS can set a cost per acre it will pay for labor and by dividing this cost/acre by the amount of acreage applied pertank10ad (i.e., a 3,000 gallon hydroseeder can apply approximately 1/3 acre per load ofBFM) the USFS will be able to monitor not only the amount of tank1oads, applied, but be able to check this against the material inventory on a daily basis. As mentioned before, in past remediation events, this procedure has fucilitated effective and timely coverage, anticipated material and labor requirements, and eased inspection and payment procedures. We would also suggest that a water truck be made available for refilling the hydraulic seeder so as to reduce turnaround time for filling, mixing, and application. Supportive Practices for Rem..inder of Affected Area As was mentioned during our briefmeetings on August 5 and 6, there are many supportive practices, controlling sediment primarily, which should be integrated into the overall remediation effort. Since you asked for our opinion concerning the practices already in operation, we will offer that in of themselves, they all appear to have the potential for reducing erosion and/or downstream delivery of debris and sediment. The Madge roto-tiller procedure should break up overland flow and allow for some infiltration of runoffinto the area tilled by the ma<;hine, The revegetation of these contoUr strips should act as filters to intercept rainfiIIl and trap sediments as well. The contour felling of trees across slopes should also reduce runoff velocities, although brush p1acemeot in gullies does not appear to capture sediment effectively unless the brush is in inrimate contact with the soil surliice. An a1temative procedure we observed were some straw bales being used to reduce water velocities and retain sediment in some of the drainages on the west side of County Road 126. Although initially effective, these check structures now appear to be either filled with .,.n;ment or overwhelmed and broken away. We have some suggestions for repair and modification of the check structure inmlnlltions. 3 II:\IW'A'lIUFALClDOC fiW(I:31 AM)
