SBA Taxiways E, A3, and A5 Pavement Reconstruction Project

This Project consists of four different parts; Taxiway E “Echo”, Taxiway A3 “Alpha Three”, Taxiway A5 “Alpha Five”, and infield stormwater infiltration trenches. The three taxiways at the Santa Barbara Municipal Airport (Airport) require varying levels of large-scale pavement repairs to restore the asphalt concrete pavement to like new condition. Taxiway E will undergo a full-depth reconstruction for approximately 1,700 feet in length. During the reconstruction process, the Airport will reshape the geometry of Taxiway E, therefore expanding the amount of impervious pavement to enhance the safety and circulation of large commercial aircraft in the area south of the Airport terminal. Taxiway A3 will require a mill (grind) and fill (repave) rehabilitation, less intrusive than reconstruction, for a portion of the total taxiway, approximately 200 feet in length. Taxiway A5 has the most minimal pavement rehabilitation planned that only requires a protective seal coat applied to the taxiway surface for the whole length of the taxiway, approximately 300 feet. In response to the expansion of impervious pavement, the Airport will also add new infield stormwater infiltration trenches, primarily constructed of gravel, to encourage slow stormwater infiltration into the surrounding soils. Changes to the geometry of Taxiway E will also require relocation of taxiway edge lights along with its buried electrical conduit and modifications to the buried storm drain piping and infrastructure.
