APPLICANT: Renton Technical College
PROJECT NAME: RTC Automotive Complex Renovations/Additions
PROJECT DESCRIPTION: The applicant Renton Technical College, is requesting Site Plan and

Automotive Complex area of the college campus. The new K4 building would house shops, classrooms, auto
parts and tools department and administration spaces. The 145,200 sf site is in the Industrial Light zone with
adjacent residential zoning. Vehicle access would stay the same to campus and pedestrian access through the
renovation area would add a north -south corridor through building K1. Landscaping, site furnishings and bicycle

approximately 2,600 sf for a new entry for K1, utilities, and display and landscape areas. The applicant requests
three modifications for parking, street frontage improvements, and refuse and recycling areas. Documents
