Looking into Raw Land Development to Subdivide

[Connor Darrow]

Hi all,

I have a 6.5 acre residential zoned property in Birmingham, AL. We were interested in creating a small gated subdivision of 13-15 houses. We have quotes from engineers to do the surveying and engineering services required to subdivide the property. However, before we go through with it, we wanted to determine how much it would cost roughly for sewage lines, water, power, land clearing and landscaping, roads, lighting, curbs, etc. Does anyone know how I can find out a rough estimate before involving the engineer and using the drawings for a quote? Just want to make sure this is a worthy investment and not something that isn't worth the time or effort. From what I understand online the typical price for infrastructure per lot is around $40,000? I am told that locally sewer alone costs $100-200 per linear sq ft and we need at least a 160ft extension to get sewer onto the property and it has to run along our road as well to connect to each house.
Thanks in advance
