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 bloody murder, but it beats trying to turn onto or off of Loch Lomond at rush hour.
