0 2.05.3 <br />Light Use Roads <br />New and existing light use roads are or will be located on ridges or on the <br />most stable available slopes. <br />No part of the light use roads are located in the channel of an ephemeral <br />stream where the upstream watershed is over one square mile. The light use <br />roads are not located in any intermittent or perennial streams. <br />Light use roads will be located to minimize downstream flooding. Run-off <br />from the light use roads must flow through significant vegetation before its <br />reaches any stream or leaves the permit area. The vegetation will filter <br />sediment from the run-off and slow or stop the flow. No empirical <br />demonstration of the effectiveness of the vegetation filter is presented. <br />However, a visual inspection of the area surrounding the light use roads will <br />confirm it is unlikely the light use roads will cause damage to fish, wildlife or <br />other environmental values or cause additional contributions of suspended <br />solids to steamflow or to run-off outside of the permit area. <br />• Light use roads will not cross flowing steams, wet areas or ephemeral <br />channels where a culvert would minimize the probability of disturbance of the <br />hydrologic balance. Therefore, no culverts are or will be installed for the light <br />use roads. <br />No surfacing will be utilized for the light use roads. The light use roads will <br />be maintained adequate for the intended use of the roads. A light use road <br />damaged by a catastrophic event will be repaired as soon as is practicable <br />after the damage has occurred. <br />The light use roads used for monitoring are typically pre-existing jeep trails <br />that can be identified on Map 9, Hydrologic Monitoring Location. <br />The majority of the traffic on the light use roads is comprised of all terrain <br />vehicles (four -wheelers) or small trucks. The light use roads were used <br />during 1995 and 1996 to gather environmental baseline information and were <br />found to be constructed to adequately support the volume and weight of the <br />vehicles utilized. <br />County road 4365 lane ends at the south side of the bridge over the Fire <br />Mountain Canal._ A_private road extends from the end of the County road to _ <br />Pond K. This light use road, including the county road segment, is <br />approximately 1,400 feet long with an average grade of 7% and a pitch grade <br />. PR -12 2.05-34- 02/10 <br />/� PPAavbo <br />
