C.15 Turf Renovation (Gravesite Renovation):

C.15.1 Vegetation Removal: Existing turf is to be sprayed with a short acting non-selected herbicide designed to eliminate turf and weeds (The product “Round-up” cannot be used in the cemetery). All existing turf and weeds must be eradicated before stripping of topsoil and dead vegetation. Application to be applied by a licensed applicator to ensure appropriate rates of application and other State regulated requirements.

C.15.2 Stripping Topsoil: Strip two to four (2-4) inches of topsoil from within limits of work area and remove from work site each day. New topsoil shall be a fertile, friable, natural topsoil of loamy character and characteristic of locality.Topsoil shall be capable of growing healthy horticultural crops of grasses.

Stockpile topsoil and protect as directed by COR or designee. Eliminate foreign materials, such as dead grass, weeds, roots, stones, subsoil, frozen clods, and similar foreign materials larger than 25 mm (1 inch) in any dimension from topsoil that will be used in final grading. Topsoil work, such as stripping, stockpiling, and similar topsoil work shall not, under any circumstances, be carried out when soil is wet so that tilth of soil will be destroyed. Topsoil removed from the work area may be stored in a temporary on-site location designated by the COR(s) until removal from cemetery site at the end of work day.

C.15.3 Lines and Grades: Area must be tilled, graded and compacted to a level to provide a flowing transition through existing terrain (no depression or low line areas). A Registered Professional Land Surveyor or Registered Civil Engineer shall establish lines and grades for approval by COR and designee.

Grading shall provide a smooth transition at curbs, trees, planters and uninterrupted drainage flow into existing drains. Contractor shall notify COR or designee of any differences before requesting approval of lines and grades. Subsequent to establishment of lines and grades and COR or designee approval, Contractor will be responsible for any additional cut and/or fill required to ensure that site is graded to ensure that surface water drainage will drain to existing storm drains and that they are no standing water areas throughout the sections (such as depression and sunken graves).

C.15.4 Filling and Back Filling: Do not fill or backfill until all foreign materials have been removed from excavation. For fill and backfill use excavated materials and top soil as applicable. Do not use unsuitable excavated materials such as topsoil, construction materials and material subject to decomposition, clods of clay and stones larger than 1-inch, organic materials including silts which are unstable, and inorganic materials including silts, too wet to be stable.

C.15.5 Compaction: Compact with approved tamping rollers, sheep-foot rollers, pneumatic tired rollers, steel wheeled rollers, or other approved equipment (hand or mechanized) well suited to soil being compacted. Do not operate mechanized vibratory compaction equipment, which may damage existing liners or caskets. Sub-grade must be thoroughly tamped to compaction.

C.15.6 Topsoil: Topsoil shall be a well-graded soil of good uniform quality. Topsoil shall contain a minimum of 3% organic material. Organic material will be reflected in soil test and provided to COR. It shall be a natural, friable soil representative of productive soils in the vicinity. Topsoil shall be free of admixture of subsoil, foreign matter, objects larger than 25 mm (one inch) in any dimension, toxic substances, weeds and any material or substances that may be harmful to plant growth and shall have a pH value of not less than 5.5 nor more than 7.0. Testing for pH will be required by an approved laboratory. Copies of the pH tests shall be furnished to the COR(s) PRIOR to topsoil being placed. Amend topsoil not meeting the pH range specified by the addition of pH Adjusters. Top-dress is to be organic matter, weed free consistent with irrigation requirements to promote healthy grass. If sufficient topsoil is not available on the site to meet the depth as specified herein, the Contractor shall furnish additional topsoil. At least 10 days prior to topsoil delivery, notify the COR or designee of the source(s) from which topsoil is to be furnished. Obtain topsoil from well-drained areas.

C.15.7 Installation of Topsoil: After tilling the soil for bonding of topsoil with the subsoil, spread four (4) inches of topsoil evenly over prepared site. Incorporate topsoil into the subsoil to avoid soil layering. Do not spread topsoil when it is excessively wet or dry. Correct irregularities in finished surfaces to eliminate depressions. Protect finished topsoil areas from damage by vehicular or pedestrian traffic. Complete lawn work only after areas are brought to finished grade. The areas within the drip lines of existing trees are not to be tilled at a depth greater than three inches or backfilled not to exceed four inches from existing grades.

Contractor must protect all trees, shrubs and plants. Exceptions must be approved by COR. Incorporate fertilizers and lime into the soil to a depth of at least 100 mm (4 inches) as part of the finish grading operation. Immediately restore the soil to an even condition before any turf work.

C.15.8 Finish Grading, Sod and Sodding: Complete lawn works only after areas are brought to finished grade (approved by COR) and all vegetation has been eradicated. Sod shall be certified sod as classified in the TPI Guideline Specifications to Turf Grass Sodding. The composition of the grass species in the sod shall be the composition of the grass species in the sod shall be Zoysia grass (Palisades Cultivar). Two applications of fertilizers are required, one prior to sod placement (use a starter fertilizer 5-5-15 at the rate of .75-pounds of nitrogen per 1000 square feet and another application of fertilizer after the first mowing at .75 pounds of nitrogen per 1000 square feet.
