(A) The design, plans and specifications of every storm sewer system, cross-road culvert, storm water detention facility, ditch, swale and channel shall include provisions to show compliance with the drainage laws of the state and any subdivision thereof in effect at that time. By requiring that the subdivider or developer evidence planned compliance with drainage laws, the village assumes no responsibility to landowners or others for damage caused by noncompliance with such laws.
(B) In general, all drainage system design and construction shall conform to the State Department of Transportation’s Standard Specifications for Road and Bridge Construction (latest edition) unless otherwise modified herein.
(C) Sump pumps may be connected to the storm sewer system, but shall only enter the system above the hydraulic grade line for the 25-year design storm event. By connection of the sump pump to the village’s storm sewer system, the village takes no responsibility for the operation, maintenance or ownership of the sump pump system.
(D) All sump pumps shall be fitted with an appropriate check valve to prevent backflow of storm water. The village shall not be liable for any damage due to backup of storm water due to failure of the sump pump check valve and appurtenances.
(E) Place aggregate in maximum eight-inch layers and compact to 95%, maximum dry density ASTM D698, Standard Proctor, except for the top four feet of trench, which shall be compacted to 97% maximum dry density, ASTM D698, Standard Proctor. Lift size may be increased when it is demonstrated that compaction requirements can be met using other methods.
