The issue is that in the county, there is not a low-impact Commercial zone where you would want to have businesses opening up right next to your house. Think about a limited use zone that allows neighborhood services like a bakery, restaurant, bar, produce shop, hair salon, etc. A zone that, if the couple of parcels right next to you rezoned to this zone, most people wouldn't object too much too.
I'm thinking of a few neighborhoods in Denver that I've visited, where you walked to a neighborhood restaurant for dinner, or walked down the street to get an ice cream or a sweet after dinner. Those type of commercial developments are assets.
CN allows too many uses, and really requires larger parcels with larger setbacks. It's not what you want to plop in the middle of a neighborhood of single family residential.
KCPA encourages Planning Commission to consider the uses allowed in CN, potentially remove some of those uses, and also to consider a new zone that would be appropriate for placing in the middle of a suburban neighborhood. This would also give you a nice use pattern that could be used in Planned Residential, instead of the existing "SC" uses allowed in PR if you have enough lots / space.
