It might be a little high but I'm setting this yrs goal at 20 coon and say 5 fox red/gray combined.
you can do that. i caught that many coon in a month.
me and ron spent a month or so set for reds, and didn't connect. we were pm'ing back and forth on quackers trying to figure out what the heck we were doing wrong. broadhead(quackers) had caught about 6 reds in a week, and thought we lost it.
what happend was broadhead hit them early and found them, i had one thanksgiving week. then distemper hit around us. killed 95% of our reds. we got hit hard the year before with mange, it killed 75% of what we had that year. so we were set for nothing for at least a month. by the time we relized what was going on we lost a lot of time.
then we switched over to coon. i'm not a coon guy, never wanted to bother with them, always sold them round. but they were the only thing going besides a few grey. the coyotes holed up on a property that none of us could trap. it was a tough year. i had trouble, ron did, stiks did real bad, braodhead hit them early then switched to mink after hearing our problems, but his fur wasn't prime.
don't get caught up on numbers. sometimes it's not you, just the animals numbers are down. ron told me on years like that it will show you just how good you aren't. if you can catch that one red that is left great, but it won't be easy. also think about leaving that one red for seed and try again next year.
i'm seeing more k9's this year out there then we had for the last couple years. but i think i'll never run just a k9 line now. i really liked putting up the coon. now if i can get my basement to look like this i think i have arived as a coon trapper.

to get your numbers up you need to sread out a little. private land is great, but look at the county culverts. if your not stepping on private land you can do the culverts.

i know you have tide issues, but find those dry culverts. you can hid your traps and the coon walk them every night. newt hits them hard ,real hard. problem is your in the public eye. did you ever see the pictures of newts magnet he puts on his truck door? east coast bridge inspector, he wears a hard hat and a orange vest. he's so visable no one can see him.
if you can hide the trap, hide you setting, and use a grain bag to bring out the dispatched animal, you got it. not many people around down there during the off season, there has got to be tons of places. how about near the campground dumpsters, they feed there all summer, now it's slimm pickings. i catch coon near a campground dumpster near me. do some thinking when you drive around. the places are right in front of you, your just not seeing them yet.
