Tukwila South Element (Draft) Several watercourses, some of which may be salmonid bearing, and wetlands have been identified in Tukwila South, both in the valley and on the slopes to the east of Interstate 5 and Orillia Road South. The Tukwila South Project, being completed by Segale Properties under a Development Agreement with the City, includes the alteration of two streams and filling of several acres of wetlands. As mitigation for these alterations, stream and wetland enhancements have been completed south of South 200th Street. Additional fisheries impacts are being mitigated by construction of a 7 -acre off - channel habitat area adjacent to the Green River. A segment of the Green River levee protecting the west valley floor in Tukwila South has been reconstructed to enhance flood protection of the area and to ensure reasonable flood insurance costs for property owners. Additionally, the City has issued Segale Properties LLC a grading permit that allows the Tukwila South project to be filled well above the 100 - year flood elevation. The valley wall represents a large portion of Tukwila South. This area is predominantly vacant with some low - density residential detached single -unit structures. Landslide potential is moderate to high for portions of the valley wall. These areas are protected by Native Growth Protection Area easements and will remain undeveloped in perpetuity. Transportation, Access and Utilities Two new street projects have been completed to improve circulation in and around Tukwila South. The extension of Southcenter Parkway through Tukwila South has greatly enhanced the development potential of the area. The construction of S. 184th Place to replace S. 178th Street has provided a safer east /west connection for south King County residents Utilities, such as electric power, gas, communication, water, and sewer, have been constructed in Tukwila South and are capable of serving the envisioned future urban development. A regional surface water system for management of stormwater is being developed in Tukwila South (the south portion of the system has been constructed; the north portion will be constructed in the future). Tukwila South has excellent connectivity to the regional freeway system, with direct access available to Interstate 5 and State Route 167. Access to Interstate 405 can be obtained via State Route 167 or West Valley Highway. Mass transit to the area is currently limited and the area is not served by either light or heavy rail. 2 City of Tukwila Comprehensive Plan - Tukwila South Element PC Review Draft Z: \DCD N CLERICS \PC LASERFICHE PACKET \2014 PC PACKETS \07 -22 -14 AND 7- 24- 14 \A1_TUKWILA SOUTH ELEMENT, DRAFT FOR PC.DOCX 16
