Central Lateral defines the hydrological character of this landscape in the San Luis Valley, cutting a diagonal path across a grid-dominated agricultural region. This 2010 survey illustrates a sophisticated irrigation network necessary for high-altitude farming, where the Costilla Canal and South Lateral distribute water through a strictly partitioned landscape. The road system follows a rigid section-line geometry, with corridors like County Rd 112 and Stanley Rd providing access to expansive field plots. The map reveals the transition between these vast agricultural tracts and the emerging residential developments indicated by named clusters like Jasper Cir and the numbered streets of 1st Ave and 2nd Ave in the northeast. This interplay between the historic irrigation infrastructure and modern road naming conventions highlights the continued evolution of water-dependent land use in Alamosa County.
