• 13 . Wetland B (Category III) - The required 50 foot wetland buffer may be reduced to 25 feet if the remaining 25 feet of the buffer is enhanced with native plantings. 14 . Wetland C (Category II) - The buffer for this wetland shall be 75 feet. Buffer width averaging may be applied provided that the minimum buffer width is not less than 37. 5 feet. 15. The developer shall submit calculations which show that the reconfigured wetland buffers in Wetlands A, B, and C meet buffer width averaging and buffer width reduction requirements as approved by the Planning/Community Development Department. 16 . Wetland B proposed fill area shall be mitigated at a ratio 1 . 5: 1 . The developer is also required to stockpile the hydric soils and plant layer from the road crossing on wetland B. 17 . Submit a wetland and buffer creation/enhancement and monitoring plan for the mitigated wetlands areas. The plan shall be prepared by a qualified wetland biologist and shall include: wetland mitigation areas at the ratio of 1.5:1 for areas filled within Wetland B; area calculations for all buffers in Wetlands A and C to demonstrate that the total area provided meets ESA Ordinance requirements set forth in conditions 10, 11 , 12; and a planting plan which uses native species found in the adjacent established wetland areas. To the maximum extent possible, cuttings from wetland vegetation on-site shall be used for propagation of mitigation plantings. The monitoring plan shall contain a hypothesis and clearly stated goals and criteria; it shall monitor vegetation mix and coverage, wildlife, usage, hydrology, water quality, hydric soils, and invertebrates; and it shall include contingency measures and a long term maintenance plan for the removal of invasive species such as purple loosestrife. (See Attachment A" For Proposed Hypothesis) 18 . Monitoring of the wetlands mitigation area must be for a period of 5 years. The standards of success for the wetland are set forth in the attached model monitoring plan. The plan shall include the creation of a functional wetland that exhibits a range of functional values that are similar to other "relatively" undisturbed wetlands within Woods Creek watershed, including native vegetative coverage (area 1) . 19. Wetlands A, B, C and their buffers must be noted as Environmentally Sensitive Areas. An ESA covenant must be recorded to provide for their long term protection. 4
