 All areas, except slopes constructed with topsoil, peat or muck, should be covered with a layer of topsoil approximately 4 inches (100 mm) thick, or as otherwise shown.  After the spreading operation, all large lumps and clods are to be broken down by some effective means and stones over 2 inches (50 mm) in diameter, roots and other debris removed from the surface.
 ==MATERIALS==
@@ Line 34: / Line 35: @@
 Whenever an area is to be topsoiled, seeded, fertilized and mulched, it is desirable to pre-measure this area so the Contractor may determine amounts of materials to be placed in order to comply with the prescribed application rate.  These pre-measurements should be kept in the project records to verify that application rates were reasonably close.  Application rates are detailed in the specifications.  Particular care should be paid to getting enough adhesive on mulch, as this is often a problem area that may result in a price adjustment on mulch when the adhesive is below the prescribed application rate.
 ====Topsoil====
@@ Line 45: / Line 47: @@
 Topsoil surface will be measured and paid for according to the item of work appearing in the contract.
 ====Seed====
@@ Line 50: / Line 53: @@
 Good quality seed, selected from the Qualified Products List and meeting the required specifications, is essential for a good catch of grass.  The operation of seeding must be considered important and critical.  Drilling, broadcasting and hydroseeding are among the methods of sowing currently in use, with better results ensuing from the drilling method.
 ====Mulch====
@@ Line 57: / Line 61: @@
 Policy requires that mulch be weighed with tickets made out in triplicate and signed by the department representatives observing the weighing.  The ticket must also report the number of bales used.  In some areas, where the cereal leaf beetle has infected crops, a certification of inspection by the Michigan Department of Agriculture may be required.  Special Provisions will detail the requirements in such instances.
 ====Mulch Blanket====
@@ Line 64: / Line 69: @@
 Staple material will be frangible (plastic) when used in areas subject to future mowing.  These areas include a 20 foot (6 m) strip along the top of the foreslope adjacent to the shoulder and everywhere on urban projects.  On all other areas the use of steel pins for anchoring mulch blankets will be permitted.
 ===Sod===
@@ Line 69: / Line 75: @@
 Before sodding operations begin, areas will be dressed to plan tolerance.  The earth beds will be thoroughly watered just before laying the sod.  Sod placed in dry weather should be watered frequently as directed by the Engineer.  This work is covered by the pay item '''Water'''.
 ====Source====
@@ Line 74: / Line 81: @@
 As noted in Section [http://mdotcf.state.mi.us/public/specbook/files/2012/917%20Landscaping%20Materials.pdf 917] of the Standard Specifications for Construction, the source of sod material should be an area with soils similar to the predominant soil types upon which the sod will be placed along the roadway, with exceptions as noted for sandy soils.  The proper source of sod is one of the prime factors affecting successful establishment.  Source fields that contain perennial grasses free from noxious weeds and that have been recently used as pasture land provide dense turf.  The grazing activity accomplishes the same beneficial results as periodic mowing and fertilization.  The Region Resource Analyst may be of assistance in determining the suitability of the sod field.
 ====Substitution====
@@ Line 79: / Line 87: @@
 The substitution of nursery grown sod in place of pasture land sod for Class B sod should not be made unless the nursery grown sod contains grass species that do not require intense lawn type maintenance.  Roadside turf must be sustained without fertilizing and with limited maintenance.  The bent grasses and Kentucky bluegrass are common nursery grown sods that are unsatisfactory for roadside turf due to their high maintenance requirements.  Remember that the 3/4 inch (20 mm) soil thickness and soil type must also apply to nursery grown sod for Class B sod.
 ====Mowing====
@@ Line 84: / Line 93: @@
 After a suitable sod field is located and before actual sod lifting operations commence, the grass should be mowed to a height of 3 to 4 inches (75 to 100 mm) above the ground surface for Class B sod.  Reduction of grass top growth cuts down on moisture loss between lifting and placement and also stimulates root growth, both of which are important to rapid establishment of newly place sod.
 ====Cutting====
@@ Line 89: / Line 99: @@
 One of the most important aspects of cutting sod is to assure the use of sharp cutting blades (so cutting is not being replaced by tearing).  The minimum sizes and thickness are described in the [http://mdotcf.state.mi.us/public/specbook/2012/ Standard Specifications for Construction].  The thickness measurement includes only the soil and roots portion of the sod.
 ====Handling====
@@ Line 94: / Line 105: @@
 Transportation and handling of sod from the cutting field until it is placed on roadside areas should be conducted to retain the original soil material around the root mass.  Sod should not be thrown to its final position, but chutes or pallets should be used to get it very near its final position, or it should be hand placed.  Almost equally important is the retention of soil moisture in the sod being moved.  Any operation that results in loss of either soil or moisture can seriously retard or prevent satisfactory sod establishment.
 ====Placing and Tamping====
@@ Line 101: / Line 113: @@
 Once the sodding operation is proceeding in a satisfactory manner, inspection is necessary only on an intermittent basis.  Approximate pay quantities should be turned in daily.  Sod will be final measured in place, by the square foot (square meter).  Inspection should be aimed toward an “end product” or performance criteria.
 ==CONSTRUCTION==

 All other roadside areas will be seeded and mulched, except that the following areas will continue to be sodded: selected ditch bottoms, road culvert ends adjacent to selected riprap areas, sodded spillways, fill slopes at stream crossings and where necessary in areas of potentially high erosion.
