In April 2015, a salvage excavation was conducted at 5 Ha-Tzabar Street in Kefar Sava (Permit No. A-7386; map ref. 194305–28/676421–45; Fig. 1), prior to construction. The excavation, undertaken on behalf of the Israel Antiquities Authority and financed by Mr. Solomon Kislevski, was directed by D. Masarwa, with the assistance of Y. Amrani (administration), R. Mishayev (surveying and drafting), A. ‘Azab (consultation), A. Gorzalczany (guidance), C. Ben-Ari (GPS), P. Gendelman (pottery reading) and M. Shuiskaya (pottery drawing).
Stratum II. In Sq E3 walls (W106, W110, W111) of three rooms (L112, L116, L118), built of medium and large ashlars, were exposed, some extending outside the excavation area. A floor of crushed chalk was revealed in Room 112, and a section of a floor paved with small and medium fieldstones in Room 116. Two construction phases were identified in Sq E6. The early phase (IIb) consisted of a wall (W104) built of small and medium ashlars and fieldstones. A section of pavement (L113) made of small and medium fieldstones abutted it from the east. The later phase (IIa) included a wall (W103), consisting of a single course of small and medium ashlars and fieldstones, which adjoined W104 from the east and formed the corner of a building. Pottery dating to the Byzantine period was found in this stratum, including fragments of bag-shaped jars (Fig. 7:1–3) and a Gaza jar (Fig 7:4).
Stratum I. In Sq E3 a section of a wall (W108) built of roughly hewn fieldstones was exposed; an installation (L115) built of small fieldstones abutted it from the west. A small segment of pavement (L102) consisting of small and medium fieldstones was also uncovered. In Sq E6 a habitation level (L101) with small and medium fieldstones was revealed. Pottery dating to the Early Islamic period was found, including fragments of a bowl (Fig. 7:5), and jugs (Fig. 7:6, 7). A cooking pot sherd from the Ottoman period (Fig. 7:8) was discovered on the surface.
Walls and floors which were part of the ancient settlement of Kefar Sava in the Byzantine and Early Islamic periods were exposed. Remains of the same settlement were also revealed in adjacent excavations. Finds from the Ottoman period are indicative of later remains at the site.
