I live in The Gap and have so for 17 years who said its was a storm corridor the only storm that was an issue that I am aware of was in 08. Don't base your decision on it as a storm corridor there are bigger issue with your insurance company not paying a claim

.
Waterworks Rd can be an issue but I am in and out before traffic becomes an issue but I don;t feel its any worse than Moggill Rd, Milton Rd, Corronation Drive, Ipswich Rd, Annerally Rd, Riverside Expressway (hmm only at midnight

) Gympie Rd, etc etc any main road into the city is Shi$ at peak hour.
Bus service is great, no train station, plenty of schools both state and private, main shopping centre The Gap Village Shopping Centre / The Gap Markets, if thats not good enough 2k away is another shopping centre at Keppera or I guess 5k is Brookside shopping centre or Ashgrove which has Coles, woolies, and aldi.
The city is 11klm. 20 minites puts you on either the freeway to the north or to the south.
