We present the results from an Atacama Large Millimeter/Submillimeter Array(ALMA) 1.3 mm continuum and $^{12}$CO ($J=2-1$) line survey spread over 10square degrees in the Serpens star-forming region of 320 young stellar objects,302 of which are likely members of Serpens (16 Class I, 35 Flat spectrum, 235Class II, and 16 Class III). From the continuum data, we derive disk dustmasses and show that they systematically decline from Class I to Flat spectrumto Class II sources. Grouped by stellar evolutionary state, the disk massdistributions are similar to other young ($<3$ Myr) regions, indicating thatthe large scale environment of a star-forming region does not strongly affectits overall disk dust mass properties. These comparisons between populationsreinforce previous conclusions that disks in the Ophiuchus star-forming regionhave anomalously low masses at all evolutionary stages. Additionally, we find asingle deeply embedded protostar that has not been documented elsewhere in theliterature and, from the CO line data, 15 protostellar outflows which wecatalog here.
