SDOT 2009 Sidewalk Design Services

SDOT 2009 Sidewalk Design Services
City of Seattle

TranTech completed the PS&E package for a portion of SDOT 2009 Sidewalk Design Service Program. The project proposes new sidewalks, planting strips, bio-infiltration swale, bio-retention cell, curb & gutter, curb bulbs, ADA curb ramps, trees, and driveway accesses for five (5) neighborhood streets and one (1) secondary arterial in City’s southeast neighborhood. Currently these streets have various roadway widths, gravel shoulders, with discontinuous sidewalk and curb & gutter links.

The project applied SDOT’s ROW Improvement Manual and Natural Drainage Manual as the design guideline for all elements including bicycle paths, parking allocation, driveway access slopes, street illumination requirements, tree locations related to underground utilities, and other Low Impact Development (LID) applications.
