Abstract: We introduce the Local Volume Legacy (LVL), a Spitzer Cycle 4 IRAC and MIPS Legacy survey of a complete sample of 258 galaxies within 11 Mpc. The broad goal of LVL is to provide critical insight into two of the primary processes that shape the growth of galaxies: star formation and its interaction with the interstellar medium. This goal will be achieved by investigating the spatially-resolved star formation, dust, and red stellar populations of galaxies that have been drawn from a statistically robust local sample, in which the full diversity of galaxy properties (e.g., luminosities, surface brightnesses, metallicities) are represented. Our tiered sample includes: (1) all known galaxies inside a sub-volume bounded by 3.5 Mpc, and (2) an unbiased sample of S-Irr galaxies within the larger, and more representative, 11 Mpc sphere. LVL will produce a multi-wavelength census of the Galactic neighborhood, extending to the faintest limits of the galactic luminosity function and exploiting the highest spatial resolution and absolute depth achievable with Spitzer. Our rich suite of ancillary data includes Hα and UV imaging from the GALEX 11HUGS and NGS surveys, stellar population mapping from the HST ANGST Treasury survey, H I mapping with the VLA and GMRT, optical broad-band imaging and spectroscopy. LVL will homogeneously fill in critical gaps in the current Spitzer coverage of the LV, provide SED coverage from the ultraviolet to the far-infrared, and thus supply the community with a core archival dataset on the Galactic neighborhood.
