In the event that a rainfall should occur during construction, the contractor shall pump around site drainage to a sediment trap or basin to prevent any additional impacts to the stream. 2. Wetland crossings: initial disturbance of these areas shall be limited to only that area minimally needed to allow passage of construction equipment to prepare for the installation of the crossing and to execute upland construction on the opposing side of the crossing. Grubbing or land disturbance of the subject area shall not be performed until the culverts, backf ill material, erosion and sediment control materials or devices sufficient to substantially complete the construction and stabilization of the crossing are staged or stockpiled at the location. Due consideration shall be given to impending inclement weather conditions that may adversely affect the completion of the crossing in the shortest time practicable. 3. Drainage work shall be completed in the minimum time necessary. 4. Stream and Wetlands information taken from Construction Sequence: 4. No construction of the drainage for the wetland impact shall commence until all materials needed for the impact are staged an site, and the temporary dams are installed to impede flows. 5. Establish clearing limits per approved plans. Clear and grub impact area as needed. Immediately install the temporary dams upslope of the headwall. Temporary seed and mulch disturbed area. Do not clear or disturb any unpermitted areas. 6. Install drainage. Fill, compact and finish grade area 7. Install permanent ground cover (sod) on slopes near the headwall and pipe outlet. 8. Install silt fence at toe of fill slope and as needed to prevent erosion. 9. See the construction plans for additional details. 10. See wetlands permit for additional requirements.

Install erosion control fabric along ditch banks. Do not clear or disturb any unpermitted areas. 2. No construction of the crossing shall commence in the wetlands until all materials needed for the crossing are staged on site. 3. When possible, work in the wetlands shall be done during periods of dry weather. 4. Work in the wetlands shall be completed in the minimum time necessary. 5. Contractor shall install temporary sand bags and/or sheet pilings in the stream prior to construction and bypass water as needed via a pump around. Pump around shall discharge into a rip rap lined basin or a sediment bag to keep sediment out of stream. 6. During excavation, stockpile the top 12"t of topsoil, and reuse topsoil as the top layer of soil when backfilling. 7. Install silt fence at top of ditch bank and at wetlands line to prevent erosion. 8. If wetland areas are disturbed, outside of the impact areas, they shall be regraded to original contours using topsoil for the top layer, and the stream banks shall be seeded, with annual seed, then lined with high velocity excelsior matting then staked with live willow stakes at 3' on center to stabilize the banks to 5' beyond the top of bank. 9. See rest of design plans for additional detail. 10. See wetlands permit for additional requirements. David L.
