Engineer may stop work on the project until exposed <br />areas receive the designated turf establishment. <br />B. Do not perform work on areas that are so wet that equipment operation <br />causes tracking and compaction of the ground or when the soil is in a non- <br />tillable condition. <br /> <br />3.2 SEEDBED PREPARATION <br /> <br />A. Seedbed is defined as the soil designated to support turfgrass and/or sod, <br />approximately 6 inches in depth below the design surface or as directed by <br />the Engineer. <br />B. Correct irregularities in finished seedbed surfaces to eliminate depressions. <br />C. Disk, harrow, rake or grade the seedbed until it is free of clods and roots. <br />D. Remove roots and woody plants over 1 inch in diameter. <br />E. Leave final surface in a roughened condition. <br />F. Avoid surface crusting of the seedbed after rainfall or compaction, prior to <br />turf establishment. Disk, harrow or rake to loosen soil surface. <br />G. Grade the seedbed adjacent to existing turfgrass or pavement for areas <br />receiving sod to permit sod to be flush with adjacent surfaces. <br />H. Protect prepared seedbeds from damage by pedestrian or vehicular traffic. <br />I.
