Common use of SITE RESTORATION PLAN Clause in Contracts

SITE RESTORATION PLAN. TENANT shall submit a site restoration plan to DISTRICT for its approval prior to removing any dredged material from the Premises. This plan will demonstrate an understanding of the following site-specific conditions and criteria: i. Dredged Material Management Area (DMMA) NA-1 was designed with a stabilized permanent access ramp that enters the site from the south-western corner and terminates inside the basin at the north-western corner. Under current conditions, some of the interior portion of the access ramp may be buried under fine sand. TENANT shall pay strict attention to the location and grade of this ramp, which is stabilized with road base rock, so as not to excavate into the ramp. ii. The DMMA NA-1 dikes/ramps are constructed with a 3:1/20:1 slope, contain complex and expensive instrumentation and drainage features and required two years to properly settle before being used. At no time shall the TENANT excavate into the existing slopes, benches, or access ramps. TENANT shall install survey stakes approximately 75 ft from the centerline of the dike crest and shall not excavate within 75 ft of the dike crest unless DISTRICT representatives are on site to observe. Preferably, TENANT will utilize GPS enabled excavation equipment to ensure that operators know precisely where the “as-built” berms and benches are located. In the event that TENANT excavates into the pre-existing berm, material shall be replaced, recompacted, and tested to ensure that density and compaction specifications are met. These dikes could be very expensive to repair or replace if damaged. iii. The Tenant must ensure the perimeter ditch is not blocked with fill material. Tenant shall also ensure that the perimeter ditch does not overflow onto neighboring property. a. In the event that the perimeter ditch water levels rise to within 6” of the ditch top of bank the Tenant will be required to continuously pump water from the perimeter ditch back into the DMMA (or other engineer approved solution) to avoid overflowing the ditch. iv. The Tenant will be permitted to ▇▇▇▇▇▇▇ the DMMA with their own mechanical pump. v. TENANT shall grade and/or fill the top and interior surfaces of the impoundment dike and the floor of the impoundment area to their original constructed configuration, in accordance with as-built plans provided by the DISTRICT. Any temporary access ramps shall be removed. Any permanent roads/ramps used by TENANT shall be restored with road base or shell rock to their original configuration. Following such grading and filling, TENANT shall re-stabilize the interior side slopes of the impoundment that are exposed by the spoil material removal with sod or grass seed. TENANT shall be responsible for repairing any erosion or washouts until the sod or grass is established. vi. Once the sediment removal is completed, the remaining interior basin will be re-graded so that drainage freely flows toward the weirs. A trench or ditch around the interior of the site will not be approved as an alternative to the interior grading described above. vii. TENANT shall be required to restore any potentially permanent impacts to the salt ▇▇▇▇▇ within the pipeline ingress and egress corridor. Permanent impacts are defined as any significant ruts, holes, washouts, tracks, or damaged vegetation. TENANT will be required to replant any permanently damaged salt ▇▇▇▇▇ vegetation.
