No. 2010-013) ANALYSIS FINDING B.l B.2 On-site stormwater management that conforms to the specifications of the Stormwater Management Satisfied Manual for Eastern Washington (2004) is required of this development. A conceptual stormwater plan was submitted with the preliminary devel opment plan showing potential locations for stormwater systems. Structures of stormwater systems shall not be placed within identified wetlands or in areas where Conceptual layout provided in exhibits 3 and 4 appear to meet the cultural resources are known to exist. Stormwater systems shall be designed to store stormwater generated requirements in relation to location restriction (ie no wetland or by a 24-hour, 25-year storm event. Stormwater system designs shall be prepared and stamped by a civil cultural resource areas). The applicant states that they will work with engineer licensed in the State of Washington. The final stormwater system design and locations shall be the appropriate authorities upon approval to meet the standards presented to Public Works and approved by the County Engineer prior to final approval. The stormwater required. Detailed plan will be submitted at final system construction shall be certified by a licensed engineer.

B.3 Stormwater and surface runoff generated by this project must be retained and treated on site in accordance Exhibits 3 and 4 outline 4 storm water retention areas throughout the Satisfied with regulating agencies' standards, and not be allowed to flow onto WSDOT rights-of-way. project area to contain runoff. Detailed plans will be submitted at final B.4 Wetland Areas and Buffers and Stream: Wetlands A, B, C, and D, and Stream A and their associated Satisfied: Stream A buffers shall be shown on the face of the final development plat and on the final development plan. travels through the Exhibits 3 and 4 demonstrate the locations of the four wetlands noted. center of B and A. Stream A is described in the critical areas report (exhibit 7) as running Buffers for both wetlands are displayed north through Wetlands A and B, but is not indicated on the site plans on the final submitted. Final plat and development plan will require locations and development map, any associated buffers to wetlands and streams. which exceed the stream A buffer requirement. B.5 Wetlands B, C, and D: Wetlands B, C, and D, and associated buffer areas of at least 20 feet (KCC Associated buffer areas of at least 20 feet shall be located within Open Satisfied 17 A.04.020), shall be located within Open Space tracts. Space tracts within the Dunford PUD. See attached critical areas report ( exhibit 7). B.6 Wetland A : Wetland A is located near the proposed access road from US 97 . The applicant has indicated Exhibit 7 ( critical areas report) states a general recommended Satisfied : that road construction may result in wetland impacts. Kittitas County requires, to the extent practical , a buffer of20 feet for Wetland A. Wetland A , according to exhibits 3 zero net loss of wetlands (KCC l7A.04.015).
