The County Engineer, when by such agreement all such duties devolve upon him, may after his performance thereof, make the aforesaid certification upon the final map, and when by such agreement said duties are apportioned between the County Engineer and the City Engineer, it shall be sufficient if each shall, after the performance thereof, make a certification on the final map, touching upon the duties performed by him.
