Atherton Drive is turning into Manteca’s apartment row. There are already 1,312 apartment units built, under construction or approved along Atherton Drive. That includes 603 already built, 428 under construction, and 281 that is being allowed in the new Union Crossing development anchored by Living Spaces southwest of the 120 Bypass and Union Road interchange. Manteca’s largest apartment complex yet — the 428-unit Valencia Place — is now under construction on 20 acres immediately east of Bass Shops between the 120 Bypass and Atherton Drive. The nearly $100 million project is being built in two phases. The second phase that backs up to the 120 Bypass will be built after the phase now being built along Atherton Drive is completed.
