Acquisition and Relocation Acquisition is a mitigation technique whereby a floodprone property/structure is purchased from a willing seller by an entity (usually governmental). The structure is removed from the site, and the vacant property is usually left as open space in perpetuity. Relocation involves moving a floodprone structure out of the flood hazard area to a safe location on a new piece of property. The original property, as with acquisition, is usually left as open space in perpetuity. D. WATERSHED MITIGATION MEASURES 1. Revegetation Revegetation of the burned watershed is essential for the reduction of storm runoff, erosion, and sediment production. Three reports entitled "Burned Area Emergency Rehabilitation - Buffalo Creek Wildfire, Pike National Forest" (BAER reports, references 13, 14, and 15) were prepared by the U.S. Forest Service. The following text was extracted from those BAER reports and edited by the CWCB. Seeding Approximately 75% of the original aerial seeding that was performed by the U.S. Forest Service was lost or moved to concentration points due to overland runoff during the summer storm events. Bare mineral soil exists in many areas and seed will readily blow or run off the soil surface. Due to the bare mineral soil, further aerial seeding is not recommended without assurance that the seed will not be lost through wind and overland flow. It is recommended to reseed areas prepared by the Rotoclear operation (this operation is explained later in this report). Application of the seed should be done by broadcast methods. Species types will include I annual species (white oats) and a specially prepared mixture for decomposed granite that has been proven to be effective in past applications. It is also recommended that 1800 acres of steep terrain be aerially seeded. The steep terrain cannot be effectively or efficiently treated by other methods. This treatment is recommended in order to provide some level of protection for areas that cannot be treated by one of the other mitigation measures. 2. Erosion and Sediment Control Implementation of erosion and sediment control measures in and downstream of the burn areas should greatly assist with reducing future damages and losses. The three BAER reports were that were prepared by the U.S. Forest Service contain valuable information on erosion and sediment control practices that have been or will be completed for the Buffalo Creek burned areas. The following text was extracted from those BAER reports and edited by the CWCB. Contour Felling Countour felling is recommend on 2000 acres of the high burn intensity areas. Treatment includes hand or mechanical felling of trees, and keying and staking boles perpendicular to the 24
