The past practice around here has been to mark off a bike lane where ever there is enough shoulder to fit, provided there is enough public pressure for bike lanes. What we have in many cases (not all) are a bunch of incomplete lanes for a few miles here and there. The commissions intention is to stop that type of work which provides a hodge podge bunch of roads to nowhere, and instead improve and mark off routes that cyclists agree will be usable for transportation.
Of course we all know what happens anytime you infringe upon parking spaces. Business owners have not gotten the idea that cyclists can be customers also, but that goes back to the public perception of bicycles as toys rather than transportation.
