It sure has evolved over time. When I put in for the permit to build the 2500 sf (footprint) 2-story building in the CA back in '97, all I needed was a plat showing the proposed location of the building and any associated driveway and parking I (I just sketched it in by hand), sit in front of the Board of Appeals public hearing and answer questions, sign a short written planting agreement and done. There was one "Karen" on the appeals board that was opposed to the project but it passed easily.
More recently, I had to pay Bill Higgs' company to do detailed "Critical Area Plans", with drawings, specs, new survey etc. and it cost me almost $4000 for each one. It gets worse...the design and drawings of the 1200' "living shoreline" project I recently got approved cost far more than that and the process took over 4 years. ;-(
