I saved a PDF version so that I dont lose the info if they find out and lock it up. It's a general guideline. Based on where you are doing something you can adjust it as needed. e.g. high cost of living area like west coast, add 20~30%. Super remote areas, add 20%, cheap areas, -15% etc. But the last summary itself is a good guideline of what to expect and to play it conservative. "*The cost of complete double-loaded street improvements with the components indicated above totals $280.00 to $335.00 per linear foot of street in ordinary level subdivisions, or from $180.00 to $235.00 per front foot of lot, including side street allowance. Costs may run twice as much for extreme hillside conditions."
