The contractor or developer shall furnish the trench backfill material and shall appropriately dispose of all surplus backfill material. (Amd. Ord. 5653 - 11/1/21)
I. Construction Methods. The trench shall be excavated to a depth no less than 30 inches and no greater than 48 inches, in a manner that prevents cave-in. Excavated material shall be withdrawn and placed a sufficient distance away to prevent excavated material from reentering the trench. The trench width shall be at least six inches. Where the cable duct

a. The cable duct shall be placed in the bottom of the trench only after all existing loose granular material has been removed, and the trench area has been bedded with granular backfill material, as directed by the Director of Engineering or designee. (Amd. Ord. 5653 - 11/1/21)
b. The trench shall be backfilled by placing granular material in uniform layers no greater than six inches in depth (loose un-compacted measure). The granular material in each deposited layer shall be thoroughly in such a manner as to avoid damage to the cable duct and/or wiring.
c. No granular material greater than two inches maximum dimension shall be allowed in any layer of the backfill placement.
d. No sod, frozen material, or any foreign material which, by decay or otherwise, would cause settlement, shall be placed as backfill material. Undesirable "naturally occurring" materials such as, but not limited to, topsoil, clay lumps, broken concrete, shall not exceed five percent (5%) by weight in any one sample of backfill material.
e. Any material excavated from the trench may be used as backfill provided it does not conflict with the above, and the material is approved by the Director of Engineering or designee. However, if the material in question has been excavated from the roadway area, replacement material must be granular trench backfill regardless of what material has been excavated from the trench. (Amd. Ord. 5653 - 11/1/21)
J. Acceptance of Street Lighting System.
Once the street lighting system has been initially installed according to the specifications set forth in this Section, the Engineering Department and Public Works Department or designee shall, upon the request of the developer, inspect the system and prepare a list of items for repair (punch list) (commonly referred to as a "punch list"). The punch list shall be provided to the developer or their designee. When the appropriate repairs have been made, the Village shall accept the lighting system for luminaire maintenance only. The developer remains responsible for the lighting system and shall therefore be responsible for any damage due to construction, including cable hits and pole knock-downs. The Village shall accept the lighting system when the development is formally accepted in letter form, as written by Engineering Department or designee. (Amd. Ord. 5653 - 11/1/21; Amd. Ord. 5822 - 7/17/23)
See Infrastructure Specification Guidelines, which may be updated by the appropriate Village department from time to time.
