. c) A protective buffer strip of vegetation surrounding the permanent pool at a minimum width of one rod (16.5 feet) [this width is consistent with the draft rules developed by the Board of Water and Soi/Resources under the Wetland Conservation Act of 19lJ/ J; f) All storm water detention facilities shall have a device to keep oil, grease, and other floatable material from moving downstream as a result of normal operations; g) Storm water detention facilities for new development must be sufficient to limit peak flows in each subwatershed to those that existed before the development for the 10 year storm event. All calculations and hydrologic. models/information used in determining peak [lows shall be submitted along with the storm water management plan; h) All storm water detention facilities must have a forcbay to remove coarse grained particles prior to discharge into a watercourse or storage basin. 8.9 Wetlands. a) Runoff shall not be discharged directly into wetlands without presettlement of the runoff. b) A protective buffer strip of natural vegetation at least one rod (16.5 feet) in width shall surround all wetlands. [This width is consistent with the draft rules developed by the Board of Water and Soil Resources under the Wetland Conservation Act of jY9/.} . c) Wetlands must not be drained or fiUed, wholly or partially, unless replaced by restoring or creating wetland areas of at least equal public value. Replacement must ht: guided by the following principles in descending order of priority: 1) Avoiding the direct or indirect impact of the activity that may destroy or diminish the wetland; 2) Minimizing the impact by limiting the degree or magnitude of the wetland activity and its implementation; 3) Rectifying the impact by repairing, rehabilitating, or restoring the affected wetland environment; 4) Reducing or eliminating the impact over time by preservation and mailltenance operations during the life of the activity; and 5) Compensating for the impact by replacing or providing substitute wetland resources or environments. [Compensation, including the replacement ratio and quality of replacement should be consistent with the requirements Ollllilled in the rules which will be adopted by the Board of Water and Soil Resources to implement the Wetland Conservation Act of 1991.} 8.10 Sleep slopes. No land disturbing or development activities shall be allowed on slopes of 18 per cent or more. . 8.11 Catch basins. All newly installed and rehabilitated catch basins shall be provided wilh a sump area for the collection of coarse-grained material. Such basins shall be cleaned when they are half filled with material. 8.12 Drain leaders. All newly constructed and reconstructed buildings will route drain leaders to pCI vious areas wherein the runoff can be allowed to infiltrate. The [low rate of walcr exiling
