235.01 Description . This work consists of furnishing, constructing and maintaining
baled hay or straw erosion checks for the rete ntion of soil along the toe of fill slopes, around inlets, swale areas, small ditches, sediment basins and other areas as directed by the Engineer in accordance with the requirements sh own on the plans and these specifications. Also, the work includes removing and disposing of the erosion checks and silt accumulations as directed by the Engineer. Measurement and payment for temporary erosion checks will be made only when ordered and a pay item is included in the bid schedule of the proposal. The quantity is estimated for bidding purposes only and will be dependent upon actual conditions that occur during construction of the project.
235.02 Materials . Approved Type I or II baled hay or straw material shall be
rectangular in shape with a minimum length of 32 inches and shall m eet the requirements of Subsection 715.05. The wooden stakes us ed in securing the baled material in place shall be approximately 2 inches by 2 inches x 34 inches meeting the approval of the Engineer.
235.03 Construction Requirements .
235.03.1 General. The erosion checks shall be constructed at the locations and
according to the requirements shown on the plans or as directed by th e Engineer. Erosion checks required along the toe of fill slopes shall be constructed prior to grading operations at the site. For other locations, the erosion checks shall be constructed when directed by the Engineer. The soil shall be excavated at least three inches in depth to embed the baled material. After securing in place, a sufficient quantity of the excavated material shall be placed around the erosion check and comp acted to prevent undermining.
235.03.2 Maintenance and Removal . The Contractor shall maintain the erosion checks
and remove and dispose of silt accumulations as directed by the Engineer. When the erosion checks are no longer needed , they shall be removed and the Contractor shall dispose of silt accumulations and treat the disturbed areas in accordance with the contract requirements. 235.04--Method of Measurement . Erosion check will be measured per each by actual count of the total bales used in constructing, replacing and maintaining the erosion checks.
235.05 Basis of Payment . Erosion check, measured as prescribed above, will be paid
for at the contract unit price per each, wh ich price shall be full compensation for completing, maintaining and removal of the erosion checks and the removal and disposal of silt accumulations. Payment will be made under: 235-A: Temporary Erosion Check - per each SECTION 236 - TEMPORARY SILT BASINS
236.01 Description . This work shall consist of excavation and satisfactory disposal of
all materials excavated in the construction, clean out, and maintenance of silt basins. This work may also consist of maintenance and removal of existing silt basins constructed on previous projects. The Contractor shall construct earth dikes and overflow spillways, furnish and install outfall pipe, perforated elbows, perforated ri sers, and trash racks in silt basins where shown on the plans or as directed by the Engineer. The quantity of silt basins to be placed will be affected by the actual conditions that occur during the construction of the project. It is understood that measurement and payment for silt basins will be made only when shown on the plans or ordered by the Engineer, and a pay item is included in the bid schedule of the proposal. The quantity is es timated for bidding purposes only and will be dependent upon actual needs during construction of the project.
