Because in most cases where it claims that level of accuracy, the Cost Approach was manipulated and 'backed into' to make it fit.

Fences, IMO, are similar to walkways, driveways (hardscape or flatwork as it is called) and landscaping. I've always considered this to be site improvements and have identified them below the RCN line. Are you sure that fencing is included in the M&S improvement section? But, as to its significance, I don't think it is a big deal.
BTW, CANative asked if you include EI (Entrepreneurial Incentive) in your analysis. Since he opened that can of worms, I'll let him advocate for its inclusion (which I agree with). Whether you do or don't, I advise you to understand what it is and how it impacts the Cost Approach Analysis, and then form your opinion if it should be included or not. This way, you'll be able to defend your position if ever asked..
Developer surveys, review of development costs and sale prices of newly constructed properties and market extraction.Can you share a link for your favorite source for how to determine EI?
Local builders should (must?) also be a consideration though. Yes?
