§ 50.35 SURFACE REPLACEMENT AND SITE RESTORATION.
   (A)   General.
      (1)   This section pertains to the restoration of areas within the public right-of-way and/or acquired easements where infra-structure is being constructed. Surface restoration within the site being developed is per the direction of the owner.
      (2)   When the construction is complete, remove all surplus material and rubbish from the site or work. The portion of the surface disturbed by construction shall be rebuilt to as good condition as it was before the commencement of the work. The project site shall be promptly and regularly maintained. The contractor shall be responsible for repairs of unsatisfactory trench backfilling or other unsatisfactory contracted services.
   (B)   Pavement, curb and gutter replacements.
      (1)   In all streets, alleys or other areas that are to be paved, all backfilling shall be well compacted by hand held mechanical compaction machines per the requirements of the Indiana Department of Highways and all other governing bodies. After the trench or excavation has been backfilled, the subgrade for the new paving, curb and/or curb and gutter shall be further compacted by rolling the backfill at subgrade elevation. After examination of the backfill and subgrade compaction by the reviewing agencies, the pavement, curb and/or curb and gutter shall be replaced. Pavement and drive patch details are shown on details in § 50.38, Details 5F through 5J.
      (2)   All pavements, curbs and/or gutters shall be replaced with the same materials as that removed in accordance with the latest revisions of standards of the State Department of Highways, the county or these Standards, whichever is applicable.
   (C)   Traffic control.
      (1)   The contractor shall maintain vehicular and pedestrian traffic during all paving operations, as required per the permit.
      (2)   The contractor shall provide flagmen, barricades and warning signs for the safe and expedient movement of traffic through construction zones within the right-of-way. This shall be in accordance with the principles and standards in the Indiana Department of Transportation, Standard Specifications, latest revision.
   (D)   Lawn and grass area replacement.
      (1)   All lawn and grass areas disturbed or damaged during construction shall be restored to original or better condition. Backfills, fills and embankments shall be brought to a subgrade level six inches below finished grade. When subgrades have settled, topsoil shall be placed to a finished depth of at least six inches, fine raked and prepared for seeding.
      (2)   If the backfill, fill or embankment material is sand, an eight-inch layer of clay furnished by the contractor at his or her expense shall be spread over the subgrade and thoroughly mixed into the sand subgrade. The clay shall be mixed into the sand subgrade, then leveled and smoothed. Topsoil shall be placed and spread to a finished depth of at least two inches, and fine raked.
      (3)   Commercial fertilizer 6-12-12 or equal shall be uniformly spread over the topsoil by a mechanical spreader and mixed into the soil for a depth of two inches on areas to be seeded. This shall be done at least 48 hours before the sowing of any seed at the rate of 35 pounds per thousand square feet. The area shall then be lightly raked or harrowed until the surface of the finished grade is smooth, loose and pulverized.
      (4)   Then, the grass seed shall be sown by a mechanical seeder, and lightly raked into the surface or sown with a standard agricultural drill. The seeded areas shall be thoroughly watered with a fine spray in such a manner as not to wash out the seed. The contractor shall use care in raking in order to avoid disturbance of the finished grade and seed distribution.
      (5)   Seeding shall be done only within the seasons extending from August 15 to October 15, and from April 1 to June 1, unless otherwise permitted by the governing agencies.
      (6)   The contractor must submit a seed mixture certificate to the governing agencies before using. Grass seed shall be sown at the rate of not less than three pounds per thousand square feet and shall consist of the following mixture: 35 parts Kentucky Bluegrass 30 parts Perennial Rye 30 parts Kentucky 31 Fescue 5 parts inert matter. Hydro seeding shall be done in accordance with the Indiana Department of Transportation Specifications, latest revision.
   (E)   Mulching. Adequate mulching material following seeding and fertilizing shall be applied, followed by cultipacking; mulch shall consist of:
      (1)   Dry straw or hay of good quality and at the rate of two and one-half tons per acre;
      (2)   Wood cellulose or cane fiber mulch at a rate of 1,000 pounds per acre;
      (3)   A combination of good quality dry straw or hay free of seeds of competing plants at a rate of two and one-half tons per acre and wood cellulose or cane fiber mulch at a rate of 500 pounds per acre; or
      (4)   Manufactured mulch materials such as soil retention blankets, erosion control netting or others that may be required on special areas of high water concentration or unstable soils. When these materials are used, follow the manufacturer’s recommendation for installation. The seeded area shall be watered, maintained and patched as directed by the governing agency until the contractor’s work is completed and accepted.
   (F)   Stand of grass.
      (1)   The contractor shall be required to establish a satisfactory stand of grass to be full coverage without bare spots. This is not required for areas subject to agricultural activities.
      (2)   Within one year after work completion, the contractor shall be required to correct any defective work, such as bare spots in grass coverage, erosion, gullies and the like in a timely manner upon notification.
   (G)   Sodding.
      (1)   The areas to be sodded shall be as shown on the plans and as required by the governing agencies.
      (2)   The use of sod shall be in accordance with the State Department of Highway Specifications, latest revision. At a minimum, sod shall be fibrous, well rooted bluegrass or other approved sod, with the grass cut to a height of not more than three inches. Edges of sod shall be cleanly cut either by hand or machine, to a uniform thickness of not less than one and one-half inches, to a uniform width of not less than 16 inches, and in strips of not less than three feet in length.
