OSHA requirements shall be followed for all work on this project. 3. The Contractor shall notify "Gopher State One Call" 48 hours prior to any excavation (1-800-252-1166.) 4. The Grading Contractor shall verify all locations and elevations of underground utilities with utility companies prior to any construction, and immediately notify the Engineer of any conflicts. 5.

Any erosion control items necessary to protect adjacent properties shall be constructed prior to the start of excavation or grading work. 7. Erosion control maintenance shall be performed by the Grading Contractor, and removed as per the Contract Documents or as directed by the Owner, followed by all necessary restoration of disturbed area. 8. The Grading contractor shall provide positive drainage on the site at all times. Grading tolerances shall be 0.10' for hard surface areas. Grading tolerances for the remainder of the site shall be 0.25'. 9. The Grading Contractor shall keep public streets, parking lots, and travel ways clear of soil and debris. Daily cleaning at the construction entrance shall be performed, especially at the end of each day's work. EROSION CONTROL INSTALLATION SCHEDULE 1. Silt fence shall be installed or restored prior to any construction. Silt fence shall be located as shown to intercept runoff. The area located beyond the perimeter silt fence shall not be disturbed during construction. 2. Rock Construction Entrance shall be installed prior to grading operations. 3. All storm sewer inlets shall have inlet protection inserts installed. Inserts shall be "Road rain -Top Slab" or "Road Drain -Curb & Gutter" inlet protection devices as manufactured by WIMCO (or approved equal) and installed per manufacture's recommendations. 4. All erosion contra' 'r,stallations shall remain in place and be mai.ntclned in good condition by tree contractor until the site has been re -vegetated, at which time it shall be removed by the contractor. For proposed paved surface areas, the contractor may remove necessary silt fencing to construct roadway, while maintaining adequate erosion control in adjacent areas. 5. Sufficient topsoil shall be stockpiled to allow for the replacement of 4" topsoil for disturbed areas to be re -vegetated. 6. The contractor shall schedule site grading, utility installation and site construction so that the general site can be mulched and sodded or re -seeded as soon as possible soon after disturbance. Areas that will not be subject to construction traffic shall be seed and mulched or sodded within 72 hours of final grading. EROSION CONTROL MAINTENANCE SCHEDULE 1. Erosion control measures shall be inspected by the contractor's representative and maintained by the contractor every Friday and within 24 hours after any rainfall event larger than 1/2" until the project is completed. Maintenance requirements are as follows: silt fence - 1/3 height of fence or damaged, remove sediment and/or repair fence within 24 hours; rock entrance - refresh as necessary to conform to detail; inlet protection inserts - remove sediment after each rain event, clean or replace filter when clogged; surface water - drain and stabilize, within 72 hours of discovery; street sweeping - remove all sediment tracked onto paved surfaces within 24 hours or as directed by City Engineer. 2. Replacement - Fabric shall be replaced promptly when it decomposes or becomes ineffective before the barrier is no longer necessary. 3. Any sediment remaining in place after silt fence is no longer required shall be dressed to conform with the existing grade, prepared, and seeded with appropriate seed mix, as directed by the engineer. 4. Removal of the silt fence- Silt fences shall be removed when they have served their useful purpose, but not before the upward sloping area has been permanently stabilized.
