1991 and 7,161 in 2002. It was later merged with the local community of Block 70 but the new local community preserved the Sava quay name and had a population of 20,993 in 2011. Savski Nasip riparian zone A zone in the southwestern extension of New Belgrade, west of the Blocks 45 (Sava Blocks neighborhood) and 72 (Dr Ivan Ribar neighborhood). It is on the opposite side of the municipality from the neighborhood of the same name and makes a continuation of the Sava quay, extending into the municipality of Surčin. Lower green riparian zone is below the higher embankment with a pedestrian and bicycle path on its crown. Any construction in the zone is explicitly banned and the embankment road is allowed only for the cars with special permits (locals who have arable land in the area behind the embankment), while use of trucks and heavy equipment is also banned. The forests which developed along the bank covered by 2010. The embankment was built concurrently with the Iron Gate I Hydroelectric Power Station, which was finished in 1972, and was based on the highest water level in the Danube, to which Sava flows in shortly after this zone. The Danube's level was primary point as when the level of the Danube is high, it lifts the level in the Sava, too. Since then, the embankments were getting higher in all the upstream countries of the Danube's watershed, hence worsening the high level regime of the waters in the river because as the embankments gets higher, the water during the high levels is lifted also: the tidal waves are bigger, stronger and with the larger destructive power. Since the early 2000s, Belgrade plutocracy began building summer houses on the bank, in the protected zone despite the ban. Originally those were smaller, wooden houses but in time, as there was no official reaction, the construction of the proper multi-floor houses and villas with private peers on the river began. Owners of the villas include politicians, judges, managers of the state owned companies and known criminals. Use of heavy building machinery and trucks deteriorated the embankment itself, while the forests in the riparian zone were cut in order to fill the building ground with additional earth and gravel. That way, the riparian zone was elevated, stultifying its existence, as the area ready to accept the excess waters during floods was reduced. Another
