Exhibit F <br />Section 1010.08, Wetland Alteration Permit Standards <br /> <br />Subd. 4. Standards for Approval of Permits: No permit shall be issued unless the City finds and <br />determines that the proposed development complies with the standards as stated in this <br />subdivision 4. Approval of either a wetland alteration permit or wetland buffer permit shall <br />constitute approval of a variance to the requirements of this Chapter 1010. (Ord. 602, 8-25-97) <br /> <br /> a. Minimum Alteration in Ecological and Hydrological Characteristics: A minimum alteration <br />of a wetland may be allowed when necessary for the use of property but only when it will not <br />have a substantially or significantly adverse effect, as determined by the City, upon the <br />ecological and hydrological characteristics of the wetland. However, in no case shall the <br />restrictions set out below in Section 1010.08, subdivision 3a(1) - (6) be exceeded. Since the <br />extent of alteration which can be permitted is limited, the City, when considering a permit <br />application, shall consider equal apportionment of alteration opportunity. The alteration <br />opportunity within the wetland shall be allocated among property owners in proportion to the <br />area of wetland located within each property. (Ord. 602, 8-25-97) <br /> <br /> (1) Any alteration shall not cause a reduction in the flood storage capacity of the <br />wetland. Flood storage capacity shall be determined by analysis of the runoff from the entire <br />developed wetland drainage district resulting from both the two (2) year and one hundred (100) <br />year frequency, twenty four (24)hour SCS Type I distribution storms. <br /> <br /> (2) An alteration shall not reduce the existing water quality enhancement value of a <br />wetland under conditions of ultimate development, during both the two (2)year and one <br />hundred (100) year frequency, twenty four (24) hour SCS Type I distribution storms. Water <br />quality enhancement value of a wetland shall be determined using methods approved by the <br />City. <br /> (3) Any alteration shall not reduce the existing wildlife habitat value of a wetland as <br />measured using methods approved by the City. <br /> <br /> (4) Alterations shall be carried out so as to minimize the impact on vegetation. <br />Removal of vegetation within a wetland zoning district shall be permitted only when <br />reasonably required for the placement of structures and use of property. (Ord. 602, 8-25-97) <br /> <br /> (5) Alterations shall not adversely affect the water flow characteristics within the <br />wetland as determined by the City. <br /> <br /> (6) Storm water runoff from a development may be directed to the wetland when in <br />conformance with the Local Water Management Plan 1 and only when substantially, as <br />determined by the Council, free of sediment, debris and chemical pollutants and only at rates <br />which will not substantially disturb vegetation or increase turbidity as determined by the City. <br /> <br /> (7) The proposed action shall not cause storm water runoff from the development to <br />take place at a rate which would exceed the rate or volume of runoff as anticipated by the City's <br />Local Water Management Plan 2. <br /> <br /> 1 See Chapter 1302 of this Code. <br /> 2 See Chapter 1302 of this Code.
