I missed the Clint connection, but that does nothing to alleviate 200 units off Summit. This area needs both a couple N-S connections (new development to Golden Grove, and maybe Heather to Bon Accord) as well as an additional E-W or two... perhaps Mountain View or Lynn to Bing or Lakewood, connecting with Bon Accord?
Like so:

This would have to cross a couple wetlands/brooks, but would make road work, emergency access, commuting, etc. much easier. There's about 2,000+ people in Lakewood Heights today and likely another 700 on Bon Accord, plus about 2000 on Heather Way and in the subdivision at its northern end.
People would scream 🞵🞵🞵🞵🞵🞵 murder, but it beats trying to turn onto or off of Loch Lomond at rush hour.
