Exactly none. Not having the time or ability to spend full-time combing through the minutia in every single city council meeting in the last 28 years in anticipation of rules that would effect me at some point in time, I relied on the city council to balance the interests of its taxpaying homeowners wanting to improve their properties with the city interests in having local properties improved. We do pay them to look after our interests.
Campbell has always been a rather sleepy, laissez faire, non busy-body sort of town where reasonableness was the rule.
City councils are run by them that donated and those that show up to meetings. You can bet the left showed up for every CC meeting for the last 50 years. I have even been to a Campbell CC meeting in 1995 to help a friend of mine trying to expand his home.
