No. 2010-013) <br /> <br />ANALYSIS <br /> <br />FINDING <br />B.1 <br />B.2 On-site stormwater management that conforms to the specifications of the Stormwater Management <br />Manual for Eastern Washington (2004) is required of this development. A conceptual stormwater plan was <br />submitted with the preliminary development plan showing potential locations for stormwater <br />systems. Structures of stormwater systems shall not be placed within identified wetlands or in areas where <br />cultural resources are known to exist. Stormwater systems shall be designed to store stormwater generated <br />by a 24-hour, 25-year storm event. Stormwater system designs shall be prepared and stamped by a civil <br />engineer licensed in the State of Washington. The final stormwater system design and locations shall be <br />presented to Public Works and approved by the County Engineer prior to final approval. The stormwater <br />system construction shall be certified by a licensed engineer. The certification shall be included with the <br />road certification and is required prior to the issuance of a building permit. Road and site construction shall <br />not begin prior to stormwater system design approval. <br />Conceptual layout provided in exhibits 3 and 4 appear to meet the <br />requirements in relation to location restriction (ie no wetland or <br />cultural resource areas). The applicant states that they will work with <br />the appropriate authorities upon approval to meet the standards <br />required. Detailed plan will be submitted at final <br />Satisfied <br />B.3 Stormwater and surface runoff generated by this project must be retained and treated on site in accordance <br />with regulating agencies’ standards, and not be allowed to flow onto WSDOT rights-of-way. <br />Exhibits 3 and 4 outline 4 storm water retention areas throughout the <br />project area to contain runoff. Detailed plans will be submitted at <br />final <br />Satisfied <br />B.4 Wetland Areas and Buffers and Stream: Wetlands A, B, C, and D, and Stream A and their associated <br />buffers shall be shown on the face of the final development plat and on the final development plan. <br />Exhibits 3 and 4 demonstrate the locations of the four wetlands noted. <br />Stream A is described in the critical areas report (exhibit 7) as running <br />north through Wetlands A and B, but is not indicated on the site plans <br />submitted. Final plat and development plan will require locations and <br />any associated buffers to wetlands and streams. <br />Satisfied: Stream A <br />travels through the <br />center of B and A. <br />Buffers for both <br />wetlands are displayed <br />on the final <br />development map, <br />which exceed the <br />stream A buffer <br />requirement. <br />B.5 Wetlands B, C, and D: Wetlands B, C, and D, and associated buffer areas of at least 20 feet (KCC <br />17A.04.020), shall be located within Open Space tracts. <br />Associated buffer areas of at least 20 feet shall be located within Open <br />Space tracts within the Dunford PUD. See attached critical areas <br />report (exhibit 7). <br />Satisfied <br />B.6 Wetland A: Wetland A is located near the proposed access road from US 97. The applicant has indicated <br />that road construction may result in wetland impacts. Kittitas County requires, to the extent practical, a <br />zero net loss of wetlands (KCC 17A.04.015). In the event that disturbance to Wetland A cannot be <br />avoided: a) disturbed areas shall be replaced at a ratio of 1.5 to 1, in accordance with KCC 17A.04.050; b) <br />remaining undisturbed areas of Wetland A and its buffer shall be placed in an Open Space tract; and c) <br />prior to ground disturbance, a Wetland Mitigation Plan, showing areas of wetland disturbance and creation <br />shall be submitted to Community Development Services for review and approval in consultation with <br />Washington State Departments of Ecology and Fish and Wildlife. Prior to final development plan <br />approval, all necessary wetland replacement and features shall be constructed according to the Wetland <br />Exhibit 7 (critical areas report) states a general recommended <br />buffer of 20 feet for Wetland A. Wetland A, according to exhibits 3 <br />and 4, does not rest in the open space area indicated with blue <br />hatch as required. The applicant indicated that road construction <br />could impact wetland areas. No documentation of potential impacts <br />or Wetland Mitigation Plan was submitted. The applicant <br />expressed that this will be submitted for final platting. <br /> <br />Satisfied:
