submitted to the Planning Division. All required signs <br /> shall be in place before and during construction of the <br /> bridge. ' <br /> U. The Reclamation Plan for the north side of the Mokelumne <br /> River shall include grading and drainage details that <br /> will conduct surface runoff towards the large stock pond <br /> in the southwest corner of the site. Grading and <br /> drainage facilities shall be designed and constructed to <br /> maintain current runoff levels to the wetland area. <br /> V. The route of the access road and bridge through the <br /> riparian corridor shall be adjusted to avoid removal and <br /> disturbance of Valley oak trees and Elderberry plants. <br /> If these species cannot be avoided, a survey shall be <br /> conducted by a qualified arborist or biologist once the <br /> final alignment of the bridge and access road has been <br /> staked. Each Valley oak that will be removed shall be <br /> replaced at a rate of five to one. These replacement <br /> trees shall be five-gallon trees planted along the <br /> Mokelumne River, in the area where the existing bridge <br /> will be removed, to enhance the riparian vegetation in <br /> that area. Drip irrigation shall be provided for the <br /> replacement trees for a period of at least three years. <br /> Any Elderberry that would be impacted by the bridge and <br /> access road shall be relocated within an unimpacted area <br /> of the riparian corridor according to USFWS <br /> specification. Protective fencing shall be installed <br /> around any Elderberry in the vicinity of the access road <br /> and bridge. All details shall be shown in the Excavation <br /> Plan. It shall be the applicant' s responsibility to <br /> install all trees and plants prior to the initiation of <br /> the use and to maintain replacement trees and plants. <br /> W. Prior to construction of the access road, a survey shall <br /> be conducted for the presence of Delta button celery <br /> plants in that portion of the freshwater marsh that would <br /> be affected by the access road. If Delta button celery <br /> is identified in this area, mitigation shall be provided <br /> as designated by the USFWS. The survey shall be <br /> conducted by a qualified biologist. The location of all <br /> identified plants and the USFWS-approved mitigation <br /> measures shall be included in the Excavation Plan. <br /> X. Prior to excavation, a Habitat Mitigation Plan shall be <br /> developed and submitted to the Planning Division and the <br /> California Department of Fish and Game for approval. The <br /> applicant shall also secure a Section 404 permit from the <br /> U. S. Army Corps of Engineers, as required by the Clean <br /> Water Act. The Plan shall provide for the development of <br /> wetland habitat to compensate for any of the freshwater <br /> marsh that would be affected by the access road <br /> -5- <br />
