Resolution 5173 Wetland Alteration Pennit -- Good Value Homes Planning Case No. 506-97 - December 8, 1997 Page 2 . An)' alteration shall not reduce the existing water quality enhancement value of the wetland under conditiol1!t of ultimate development. . Any alteration shall not reduce the existing wildlife habitat value of a wetland. . Alteration... shall be carried out so as to minimize the impact on vegetation. Removal of vegetation within a wetland zoning district shall be permitted on(v when rea.'tOnab(l' requiredfor the placement of structures and use of property. . . Storm water runofffrom a development may be directed to a wetland when in compliance with the local water management plan and onl)' when substantially free of...ediment, debri... and chemical pollutants. . The proposed action shall not cause stormwater runoff from a development to take place at a rate which would exceed the rate or volume of runoff as anticipated by the Ci~v'... Local Water JI,Janagement Plan. . The quali(v of water infiltrated to the water table or aquifer shall remain substantial(l' unchanged. . No part of any sewage disposal s)'stem requiring on-land or in- ground disposal of waste shall be located closer than J 00 feet from a wetland. ~ It is assumed that the water quality of this wetland will not be negatively impacted as a rcsult of the two homes being constructed, as long as a minimum lO-foot widc natural area is left to protect the wetland. Because more than 50% of the lots will be protccted by a drainagc easement and the construction arca limited to non-wetland areas, there will be no apparent reduction in the habitat value for the wctland. To reasonably use thcse two lots, vcgctation will nccd to be removed for the construction of the homes. In addition, vegetation will be rcmoved via the filling of onc area and the excavation of another area, but this is to scrvc a greater necd of creating additional flood storage capacity that will benefit all adjoining propcrty owncrs of the wetland. Becausc of the grading that will occur, it is estimated that potentially less runoff will be dirccted to the wetland. While a manicured lawn in place of natural vegetation may elevatc the level of contaminants entering the wetland, leaving a ten-foot wide strip of natural vegetation around the wetland will help cleanse runoff entcring the wctland. Currently, all of the runoff from these two lots drain directly into thc wetland. As proposed, the grading and rooflines will direct 50% of runoff toward the street, away from the wetland. The quality of thc watcr that will entcr into thc h'TOlmd water system as a result o[this development is not expccted to differ significantly from before. These lots will be connected to the City's sanitary sewer systcm and as such will not be disposing of wastes on site.
