Rough "ratio" To Determine How Much Of Land Goes To Streets?
newbie here, so please bear with me. I know if I buy 10 acres, I have to allot some of the land for things like streets, culdesacs, whatever. Is there a rough formula you use to just give yourself a ballpark # for possible lots? Just to see if purchasing the land is worth pursuing?
Thanks,
Ginnie

typically we estimate 20% of the land will be taken up by roads, open space, amenity, etc. It really depends though- I can usually come very close to getting the gross lot yield the same or close to the zoning maximum allowed if I am doing town homes.
Ginnie,
Usually I subtract 25% from the gross square footage and then divide by the minimum lot size for SFD to determine a rough site yield--unless the parcel has physical constraints like steep slopes, floodplain or wetlands that justify deducting more land area.
In my area (PA), the municipalities have subdivision & land development ordinances. This spells out what data has to be shown on the plans by your civil engineer, and the state statute lays out the review and approval procedures that are to be followed by the municipality.
I would also add that the economic feasibility takes into account what the new home on the lot would sell for and the per-lot cost of installing the streets, curbs, sidewalks, etc.
