So I have 2 questions. Don't you have cause to be concerned about that 90 pulling apart, or blowing off during heavy rains, over time?
What if the sewer was to back up, could that 90 hold on ok?
Not critisizing, just asking your opinion.

The old 90 was installed around 1980. It wasnt leaking, but the rubbers were showing dryrot, so were replaced it . The new 90 was installed right, so if it was to blow off during a heavy rain, i have insurance. BTW the joints have all been tested by mother nature.
The sewer has nothing to do with this storm drain. It drain's into a retention pond about 60' away. There is a big catch basin tied into the drain in the parking lot and a curb drain with manhole. Unless the 15"sdr35 backed up before the catch basin the only way the water would ever back up to the 90 is if the city was under about 17' of water.
