Harstad Wetland Permit March 12, 2007 Page 3 (6) Storm water runoff from a development may be directed to the wetland when in conformance with the Local Water Management Plan and only when substantially, as determined by the Council, free of sediment, debris and chemical pollutants and only at rates which will not substantially disturb vegetation or increase turbidity as determined by the City. A stormwater management plan would be required as part of any major subdivision application forthcoming for this tract of land. Runoff issues would be considered in conjunction with proposed grading activity. (7) The proposed action shall not cause storm water runoff from the development to take place at a rate which would exceed the rate or volume of runoff as anticipated by the City's Local Water Management Plan. Rice Creek Watershed District has reviewed the tree removal proposal and does not believe there to be any impact to runoff rates or volume of runoff as a result. (8) The quality of water infiltrated to the water table or aquifer shall remain substantially, as determined by the City, unchanged by the alteration of the site. There would not appear to be any impacts to the water table as a result of the tree removals. (9) No part of any sewage disposal system requiring on-land or in-ground disposal of waste shall be located closer than one hundred feet (100') from the wetland. No sewage disposal systems would be proposed on this tract of land, either as a result of the tree removal or subsequently anticipated residential development. (10) Waste which would normally be disposed of at a solid or hazardous waste disposal site or which would normally be discharged into a sewage disposal system or sewer shall not be, directly or indirectly, discharged to a wetland. With the exception of a layer of woodchips and sawdust resulting from the tree clearing, no waste would or will be discharged into the wetland. (11) Construction erosion control measures and retention facilities shall be designed to limit soil loss from the development site to not more than five (5) tons per acre per year. Plans and supporting documentation for such measures and facilities shall be developed and approved by the City prior to commencement of construction. Rice Creek Watershed District has inspected the site and does not feel that the tree removal, in and of itself, would necessitate erection of silt fencing or other retention devices. Such measures however would be required in conjunction with future grading activity on the parcel. (12) The applicant for the wetland alteration permit shall be required to demonstrate that, after the development is completed, the conditions on the site will be stabilized such that the yearly soil loss from the site will not be greater than five-tenths (0.5) ton per acre per year.
