STEP 1: SETTING UP THE ANALYSIS BACKGROUND September 2005, the Record of Decision for the Angeles National Forest Land Management Plan was published. In November of 2005, the Forest Service issued the final Travel Management Rule (36 CFR 212). The Travel Management Rule revised Forest Service directions concerning the management, use, and maintenance of the National Forest Transportation System. In order to designate a sustainable transportation system, halt cross country motorized travel and to provide consistent over snow motorized use. The Travel Management Rule was broken down into three subparts: Subpart A Identify roads likely not needed for future use Subpart B Designate the NF Transportation System; roads, motorized trails and areas Subpart C Designate an over snow vehicle system The Angeles National Forest completed the analysis portion of Subpart A during the 2005 planning process and this Travel Analysis Report (TAR) documents what have changed since the Land Management Plan was completed and also identifies roads that today are not likely needed in the future. The overall goal is to provide a financially and environmentally sustainable road system, to meet the expectation for utilization for the National Forest Lands and to maintain a safe road system for all users of the Angeles National Forest. The Angeles NF completed Subpart B in 2011. The Forest plans to review designated routes (Subpart B) in the future and will revisit the capability to complete this project on an annual basis. Subpart C will not be completed. The Angeles National Forest currently does not have an over snow vehicle system and does not plan on a system in the future. OBJECTIVES OF SUBPART A The objective of this analysis is to inform future decisions for a sustainable and safe road system. The primary goal is to list roads “likely not needed” for future use and suggest recommendations for a sustainable road system. 5 (Draft) Scale of Sub Part A The Forest completed a detailed Roads Analysis Process (RAP) in 2005 as part of the Land Management Plan. Over 10,000 road-related comments were received from the public during the 2005 RAP process. The natural resource concerns and risks are similar today to those identified in the RAP and subsequent studies since 2005. The issues identified by the public were economic and natural resource sustainability of the existing road system, the effects of roads in watersheds and on species of animals and plants. Other major issues were too much, or too little public motorized access, and the need for more public rights-of-way. The Record of Decision was published September 2005 just prior to the issuance of the new Travel Management Rule issued on November 9, 2005. This Travel Analysis utilized the GIS resource analysis that was completed as part of the RAP. The proposed Minimum Road System was determined using the Forest Service RAP and the Forest Service multidisciplinary teams listed below validated the data as a group and confirmed or changed conclusions accordingly. The Travel Analysis Process does not lead to a management NEPA decision. It is intended to inform and focus future detailed analysis towards making site specific road decisions. Scope of Sub Part A The scope for this Subpart A Travel Analysis is the Angeles NF road system where the Forest Service has primary jurisdiction. The scope of this analysis utilized the existing spatial and natural resource data

  • Three Chumash-Style Pictograph Sites in Fernandeño Territory
    THREE CHUMASH-STYLE PICTOGRAPH SITES IN FERNANDEÑO TERRITORY ALBERT KNIGHT SANTA BARBARA MUSEUM OF NATURAL HISTORY There are three significant archaeology sites in the eastern Simi Hills that have an elaborate polychrome pictograph component. Numerous additional small loci of rock art and major midden deposits that are rich in artifacts also characterize these three sites. One of these sites, the “Burro Flats” site, has the most colorful, elaborate, and well-preserved pictographs in the region south of the Santa Clara River and west of the Los Angeles Basin and the San Fernando Valley. Almost all other painted rock art in this region consists of red-only paintings. During the pre-contact era, the eastern Simi Hills/west San Fernando Valley area was inhabited by a mix of Eastern Coastal Chumash and Fernandeño. The style of the paintings at the three sites (CA-VEN-1072, VEN-149, and LAN-357) is clearly the same as that found in Chumash territory. If the quantity and the quality of rock art are good indicators, then it is probable that these three sites were some of the most important ceremonial sites for the region. An examination of these sites has the potential to help us better understand this area of cultural interaction. This article discusses the polychrome rock art at the Burro Flats site (VEN-1072), the Lake Manor site (VEN-148/149), and the Chatsworth site (LAN-357). All three of these sites are located in rock shelters in the eastern Simi Hills. The Simi Hills are mostly located in southeast Ventura County, although the eastern end is in Los Angeles County (Figure 1).

  • Executive Summary the Ranch Fire Started October 20, 2007 Near
    USDA­FOREST SERVICE FS­2500­8 (6/06) Date of Report: 11/05/07 BURNED­AREA REPORT (Reference FSH 2509.13) Executive Summary The Ranch Fire started October 20, 2007 near Townsend Peak, southwest of Templin Highway and Interstate 5 on the Angeles National Forest. Intense Santa Ana winds peaking above 100 mph on the ridge tops drove the fire southwest across 13000 acres of the Angeles National Forest then onto the Los Padres National Forest and private lands in Los Angeles and Ventura Counties burning 58,401 acres total. Most of total acreage burned during the first 48 hours after ignition. The fire reached its final boundary on October 26, and was fully contained on November 3. Because of the speed of this fire suppression impacts on National Forest land were limited to two miles of dozer line on the Angeles N.F., and some hand line and water/retardant drops along the west side of the fire on the Los Padres N. F. Approximately 14,000 acres burned on the Los Padres National Forest, 13,000 acres burned on the Angeles National Forest, 1900 acres on the Hopper Mountain Wildlife Refuge, 1400 acres on BLM land, and 28,000 on private land near Val Verde and Hasley Canyon. The Los Padres manages 8000 acres of the Angeles National Forest within the burn perimeter and east of Piru Creek. Fifth­field watersheds within the Ranch Fire area used for BAER analysis include: Castaic, Sespe Creek, middle Santa Clara River and lower Piru Creek. The BAER team leader was assigned on October 23 and assembled a team which finalized field work for soils and hydrology by October 30 with other field work finalized on November 1.

  • 3.12 Hydrology and Water Quality
    3.12 HYDROLOGY AND WATER QUALITY EXECUTIVE SUMMARY This section describes the drainage features, stormwater quality, flooding hazards, and flood-protection improvements within the City’s Planning Area. Regulatory agencies governing stormwater quality and flooding hazards are also discussed. The City’s Planning Area is comprised of the City’s boundaries and adopted Sphere of Influence (SOI). The County’s Planning Area consists of unincorporated land within the One Valley One Vision (OVOV) Planning Area boundaries that is outside the City’s boundaries and adopted SOI. Together the City and County Planning Areas comprise the OVOV Planning Area. With implementation of the proposed General Plan goals, objectives, and policies potential impacts on hydrology and water quality would be less than significant. EXISTING CONDITIONS Surface Water Drainage Patterns within City’s Planning Area Surface water drainage patterns are dependent on topography, the amount and location of impervious surfaces, and the type of flood control that is located in an area. The size, or magnitude, of a flood is described by a term called a “recurrence interval.” By studying a long period of flow record for a stream, hydrologists estimate the size of a flood that would have a likelihood of occurring during various intervals. For example, a five-year flood event would occur, on the average, once every five years (and would have a 20 percent chance of occurring in any one year). Although a 100-year flood event is expected to happen only once in a century, there is a 1 percent chance that a flood of that size could happen during any year.
