Fill, Backfill and Landscaping No soil found on Site, or transported to the Site from remote locations, which contains debris or waste or Hazardous Materials shall be used for fill, backfill or landscaping topsoil.
Structures Airport facilities such as bridges; culverts; catch basins, inlets, retaining walls, cribbing; storm and sanitary sewer lines; water lines; underdrains; electrical ducts, manholes, handholes, lighting fixtures and bases; transformers; flexible and rigid pavements; navigational aids; buildings; vaults; and, other manmade features of the airport that may be encountered in the work and not otherwise classified herein. 10-50 SUBGRADE. The soil which forms the pavement foundation.
Surface Grade and shape the road surface, turnouts, and shoulders to the original shape on the TYPICAL SECTION SHEET. Inslope or outslope as directed to provide a smooth, rut-free traveled surface and maintain surface water runoff in an even, unconcentrated manner. Blading shall not undercut the backslope or cut into geotextile fabric on the road. If required by the Contract Administrator, water shall be applied as necessary to control dust and retain fine surface rock. Surface material shall not be bladed off the roadway. Replace surface material when lost or worn away, or as directed by the Contract Administrator. Remove shoulder berms, created by grading, to facilitate drainage, except as marked or directed by the Contract Administrator. For roads with geotextile fabric: spread surface aggregate to fill in soft spots and wheel ruts (barrel spread) to prevent damage to the geotextile fabric.
Topography Altering the existing topography of the Property by digging, plowing, disking, or otherwise disturbing the surface is prohibited, unless Grantee determines such requested action will be carried out consistent with the Restoration Plan and will be carried out in a manner that protects the conservation values. Grantor shall obtain Xxxxxxx’s written permission in advance of commencing such action.
Road Surfaces (1) Grade, shape, crown, and/or outslope surface and shoulders.
Exterior and interior functional areas and spaces of the Project, with technical and equipment requirements on each;
Drainage ▪ Prevent silt bearing road surface and ditch runoff from delivering sediment to any streams or wetlands. ▪ Maintain rolling dips and drivable waterbars as needed to keep them functioning as intended. ▪ Maintain headwalls to the road shoulder level with material that will resist erosion. ▪ Maintain energy dissipaters at culvert outlets with non-erodible material or rock. ▪ Keep ditches, culverts, and other drainage structures clear of obstructions and functioning as intended. ▪ Inspect and clean culverts at least monthly, with additional inspections during storms and periods of high runoff. This shall be done even during periods of inactivity. Preventative Maintenance ▪ Perform preventative maintenance work to safeguard against storm damage, such as blading to ensure correct runoff, ditch and culvert cleaning, and waterbar maintenance.
