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.
PAVING Provide a standard bubble map, as part of the plans, showing locations of numbered points, and a table with point number, northing and easting coordinates, description, and BL station for each point, for the following: ▪ all platted control irons (set or not), including plat boundary irons, for the entire sub-division, not just the current phase ▪ benchmarks, including TBM set with preliminary survey In addition to the required coordinate information, the following shall be included in all plans, at a minimum, as needed for construction staking on all City projects. ▪ Include copy of plat(s) on all plans, as relevant and approved by the Design Engineer ▪ Benchmarks – minimum of two City standards, four total desirable; as close to project as possible, even if TBM set with preliminary survey. ▪ Benchmark elevations must be in the same datum as the design (i.e. NAV 88 design needs NAV 88 benchmarks, not NAV 29) ▪ All control irons/identified property irons shall be shown on plans, with BL stationing and offset ▪ Show deflection angles in BL, and/or bearing/azimuth of BL sections ▪ Arterial project side streets – provide BL station at CL of intersection of the two streets, on the BL; BL station and offset to CL of side street at removal limits; include deflection angle from BL to CL of side street ▪ Existing FL/pavement grades shown at all match points ▪ Top of curb grades and stationing at all ends-of-return and horizontal/vertical P.I.’s, not just even stationing ▪ CL top of pavement grades for arterial ▪ CL elevation for streets on mass grading work @ 100’ Sta in tangent sections and 50’ on curves.
Landscaping Maintaining, tending and cultivating and (as necessary) re-stocking any garden or grassed areas including replacing plants, shrubs and trees as necessary.
