Kusa mostly developed from a former manor with few houses into a village under Soviet rule in the 1970s under the guidance of the PMK-19 land improvement brigade (Latvian: Pārvietojamā mehanizatoru kolonna, Mobile Mechanizator Column), which was draining marshes and working on other amelioration tasks for the local Soviet collective farm (kolkhoz). Block houses, a district heating system and paved roads were built. Kusa has a postal office (postal code LV-4847), primary school (Kusas pamatskola) with approximately 250 students, small shops, a hotel, saw mill, car-repair workshops and a gas station.[1]
