Unless I play it wrong or I remember wrong, you don't have to place the grassland and water tile next to the newly place one.
From the original rules, p.7 (emphasis mine):
"Terrain tile: grassland - After building a district with this symbol, the player places the indicated number of grassland tiles adjacent to the newly built district."
"Terrain tile: water - After building a district with this symbol, the player places the indicated number of water tiles adjacent to the newly built district."
Seems you played/remembered it wrong.
