It would be used for general & disaster survival in NYC and the surrounding areas. So it should be able to deal with city disasters, and woods survival in northeastern outdoors. Which means it can't contain anything that would be considered illegal to carry in the city.
Not sure if that NF pack is as big as my Mountainsmith lumbar pack, but IMHO we're looking at the usual considerations for a larger PSK: knife

, food, shelter, clothing, bodily safety and function, sanitation, and comm.
KNIFE:
- a small sturdy fixed blade if legal in city, otherwise the sturdiest folder you can find.
- For small sturdy fixed blade, I like the Swamp Rat Howling Rat.
- For folders, I like the Blade-Tech Wegner Pro Hunter & am interested in seeing the Swamp Rat folder when it comes out. I suspect the Strider folders are the strongest currently on the market, but they are a bit rich for my pocketbook.
- Swiss Army Knife or multi-tool for the other tools
- if you don't mind the weight, a 14" Gorilla Bar wrecking bar lashed to the bottom of the pack for window breaking or door breaching on your way out of a building
FOOD:
- as much bottled water as you can make room for in/on the pack (drinking, sanitation, soaking bandana for dust mask, eye wash, etc)
- handful of power/clif/nutrition bars
- honey packets from fast-food joint (instant sugar & mild disinfectant for wounds)
- peanut butter packets if you can find them (protein)
SHELTER:
- Sportsman's Space Blanket with taped edge and grommets (not the flimsy lightweight 2-ounce one that fits in your pocket). They are available for about $10 from Cabela's in red or OD green. If that won't fit your pack, a heavyweight large plastic contractor's trash bag.
- lightweight strong cord. I like mason's line. Although it can be pretty stiff, it's insanely strong & quite compact. Found in home centers & hardware stores.
- 550 paracord (more versatile than mason's line, but also more bulky)
CLOTHING:
- wear layered system day-to-day so you won't have to dedicate pack space to clothing
- comfortable, sturdy shoes or boots in which you can comfortably hike all day
- large bandana or two (big enough to fold into a triangular arm sling)
- compact rain/wind layer. I like the
Red Ledge Thunderlight jacket & pants available from Campmor.com.
BODILY SAFETY AND FUNCTION:
- first aid kit (FAK) materials like EMT scissors, bandaids, large bandage pads, hi-tack athletic or duct tape, anti-histamines for stings/allergies, anti-diarreha pills, aspirin, anti-bacterial cream
- mini swim goggles to protect your eyes from dust in city
- painters particulate masks for dust (available at home centers or hardware stores)
- sturdy leather gloves for handling debris in city or campfire pots
- any prescription meds you need
- eyeglass or eyecare items you use
- dental care items like toothbrush, small tube toothpaste, floss
SANITATION:
- hotel mini-bar of soap, mini-bottle of shampoo, etc
- baby wipes packet, unscented
- toilet paper or kleenex travel packs, put in ziplock freezer bag to protect from water
- a few plastic grocery bags for catching & disposing solid body waste in city
COMM:
- whistles for locating you in building collapse or if lost in the bush (one in pack, another on your body at all times),
Storm or Windstorm whistles if you have the pocket room, otherwise the Fox 40 or flat whistle in descending order of preference
- cell phone
- CB radio or other two-way radio
- flourescent pink/yellow/green surveyors tape
