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. ▪ Perform preventative maintenance work to safeguard against storm damage, such as blading to ensure correct runoff, ditch and culvert cleaning, and waterbar maintenance.
Irrigation An irrigation reduced pressure zone (hereinafter referred to as “RPZ”) is required for any irrigation systems and must be installed by the Developer and/or eventual lot owner and tested in accordance with the Minnesota Department of Health Guidelines for Designing Backflow Prevention Assembly Installations (hereinafter referred to as “Guidelines”). The initial test results and certification shall be submitted to the City of Maple Grove Public Works Department. Subsequently, the RPZ must be tested, per the Guidelines, at least annually by a certified tester with the results reported to the City of Maple Grove Building Department and the RPZ must be rebuilt as needed in accordance with the Guidelines. Test/rebuilt reports shall be mailed or faxed to the City of Maple Grove Building Department at (▇▇▇) ▇▇▇-▇▇▇▇. The irrigation system shall be designed and the Plans shall be modified accordingly, prior to the issuance of any permits for the development of the Property, to accommodate a 1-inch water meter and a maximum flow of 50 gallons per minute.
Grading The coarse aggregate as delivered to the mixer, shall be well graded as per IS specifications. Maximum size of aggregate used for the work shall be 20mm or 40mm or as specified in items in the bill of quantities and it shall confirm to IS: 383-1970, clause 4.2 (Table-2) However, the exact gradation required to produce a dense concrete of specified strength and desired workability shall be decided as per laboratory test by the Engineer. Coarse aggregate for use in concrete shall be well graded and shall conform to IS: 383-1970 requirements (as per Table-II) given below: 63mm 100 - - - 40mm ▇▇-▇▇▇ ▇▇▇ - - 20mm ▇▇-▇▇ ▇▇-▇▇▇ 100 - 16mm - - ▇▇-▇▇▇ ▇▇▇ 12.5 - - - 90-100 10.00 ▇▇-▇▇ ▇▇-▇▇ ▇▇-▇▇ ▇▇-▇▇ 4.75mm 0-5 0-10 0-10 0-10
Drainage Systems (1) Clear culvert inlets, outlets, and sediment catching basins. (2) Maintain waterbars, drainage dips, and other water diversion measures. (3) During active use, patrol and maintain functional drainage. (4) Repair damaged culvert ends.
Start-Up and Synchronization Consistent with the mutually acceptable procedures of the Developer and Connecting Transmission Owner, the Developer is responsible for the proper synchronization of the Large Generating Facility to the New York State Transmission System in accordance with NYISO and Connecting Transmission Owner procedures and requirements.
