I was born in Oregon and most of my childhood was here.   But I spent over 30 years in the Midwest before returning.   It always surprised me to see Oregon towns, of all sizes, that have grown through purely random growth with virtually no planning.  I think it's in our DNA, the wilderness settlers making property 'their own' to do with as they like.

This is not a plank of Republicanism.    My past home of Pella, Ia, is very conservative, very Republican.   It's also an immigrant town of Dutch settlers.   From the late 1800s till now, that town was plotted and planned.  Yards don't go unattended, homes are not dilapidated, schools, both public and private, are above state and national norms.       

The town has been plotted and planned since the last 1800s and it continues to have strict standards for both businesses and private ownership.  The advantage is that it's very non-diverse.   Eugene is a much tougher area to find consensus, but planning for growth is critical
