After machine sowing, lightly cover seed by harrowing or raking. Compact lawn area seedbeds by rolling with a 200 pound hand roller. 7. Mulching. Mulching shall comply with the pertinent provisions NCDOT 1060-5 a. Apply mulch within 48 hours of sowing seed. Apply mulch of loose straw uniformly at the rate of 2 tons per acre. Between October 16 and January 31, the application rate shall be increased to 3 tons per acre. Mulch shall be anchored to the seeded surface by discing, netting, or by other methods approved by the OWNER or Construction Manager. b. Areas to be temporarily seeded need be mulched only during the fall Section 32 92 19: Seeding Sutton Removal Plan, Rev 0 GC5770\32 92 19 Seeding.doc 32 92 19-5 December 2015 or during the summer when weather conditions are excessively hot or dry. 8. Watering. Immediately after completion of mulching, apply water thoroughly to mulch and seedbed with a fine mist spray. Water heavily once per week during dry weather until a thick cover of grass is established. 9. Hydroseeding. Hydroseeding may be used as an alternative application method upon approval of the OWNER. The use of alternative soil amendments and mulch will be considered provided the application rates comply with the rates specified in this Section. C. The CONTRACTOR shall provide silt fences as needed to prevent runoff from seeded areas until vegetation has become established. D. Upon completion of work, the CONTRACTOR shall remove from the Site cord, wrappings, stakes, and extraneous materials. The CONTRACTOR shall remove tools, equipment, and other materials, except those necessary for maintenance. Litter developing by reason of the CONTRACTOR's maintenance activities shall be removed as it accumulates. E.

F. During the maintenance period, the CONTRACTOR shall perform all mowing, watering, repair of erosion areas, replacement of cover soil and topsoil, cleaning of drainage ditches and drainage system components clogged by eroded topsoil and cover soil, and reseeding until a thick stand of grass has been produced as accepted by the Construction Manager and OWNER. Maintenance shall also include visual inspection of the cover system components for damage (e.g., penetrations of the soil cover or exposure of the geosynthetic layer). Observed damage shall be temporarily covered with a tarp or other impervious cover and notated within maintenance records maintained by the CONTRACTOR. The CONTRACTOR shall report the damage to the Construction Manager within one business day of being observed to initiate protocols to evaluate and repair the damage, and submit notification to NCDENR. G. Mow areas intended for “groomed appearance” on a schedule during the growing season and as required throughout the year to provide the desired appearance for the particular species used for erosion control. 1. The range of turf species suggested for lawns in the three growing regions of North Carolina vary as to optimum maintained height. The selected species should be maintained at a height recommended by the seed Section 32 92 19: Seeding Sutton Removal Plan, Rev 0 GC5770\32 92 19 Seeding.doc 32 92 19-6 December 2015 producer. Do not cut too short and do not allow the turf to attain a height that will cause the crop to decline or die. Consult individual seed producers and/or packaging for recommended mowing heights. 2. Mow with a mulching mower to limit the amount of clippings removed, or mow and blow in such a manner that clippings are not evident and not to adversely affect the growing capacity and/or health of the existing vegetation turf. It is important clippings are allowed to remain spread throughout the lawn area, to the extent possible, so that they might aid in building a more productive soil profile and root zone. 3. Mowing other stabilized areas to promote continued growth. Stabilized areas that are not to achieve a “groomed” appearance are to be mowed to recommended mowing heights for the particular species and as frequently as recommended by the individual seed producer to foster erosion control and ease of maintenance. In areas where it is desirable for woody native volunteer vegetation to become established, the CONTRACTOR will pay attention to mowing stakes or another indicator to protect desired woody natives from the mowing operation 4. The CONTRACTOR shall cut the grass at least once, but not more than twice per season, after a thick stand of grass is produced. The CONTRACTOR shall coordinate grass cutting with the Construction Manager or OWNER so that inspections can be conducted immediately following cutting. H. A satisfactory stand of vegetative cover shall be defined as a cover of living plants, after true leaves are formed, of the required seed species designated for use in which gaps larger than 25 square inches do not occur. I. The CONTRACTOR shall make site observations monthly to check for the presence of invasive species that could lead to unprotected soil and sediment damage and, if found, treat them immediately with the appropriate cultural practices and/or by the use of seasonally-appropriate and site appropriate herbicides. J. The CONTRACTOR shall commence post-construction maintenance within two weeks of notification that maintenance is required. Maintenance will be conducted to the satisfaction of the Construction Manager or OWNER. 3.02 ADJUSTMENT OF PRACTICES A. If the planned measures do not result in effective control of erosion and sediment runoff meeting the requirements of the General Permit for Discharges of Stormwater from Construction Activities, the CONTRACTOR shall immediately adjust his activities and/or institute additional measures so as to eliminate erosion and sediment runoff at no additional cost to the OWNER. Section 32 92 19: Seeding Sutton Removal Plan, Rev 0 GC5770\32 92 19 Seeding.doc 32 92 19-7 December 2015 B. If the CONTRACTOR fails or refuses to comply promptly, the Construction Manager may issue an order stopping all or part of the work until satisfactory corrective action has been taken. No time lost due to stop orders shall be made the subject of a claim for extension of time or for excess costs or damages by the CONTRACTOR.
