As Tammy mentioned, not all sections of Port Charlotte have both water and sewer. Some sections have county water only and there are some sections that require well and septic. It would be nice if there was a map of these areas but unfortunately...
One way you can check if a property has water and sewer is to visit the county website, http://www.ccappraiser.com. Here you can search a property address and it will tell you the county utilities currently available. It is not always 100% accurate because public works adds new sewer lines, but you can always double check by calling the county utilities department at 941-764-4300.
It would be very difficult to list each neighborhood that has both water and sewer because only a few blocks can make a difference. However, it is much easier to describe areas with county water service and then use the above site to check sewer. Or I'd be happy to check any individual home for you.
In general, the areas with county water service is most parts of Port Charlotte south and east of Hwy 776 and (and a few neighborhoods the other side), the Gulf Coves parts of Englewood with PC mailing addresses. Other neighborhoods to consider that have both are Deep Creek (part of Punta Gorda), Rotonda on Cape Haze and the area south of O'Hara off Midway and most of South Gulf Cove. There are other areas but these are the easy to describe.
You can also visit the Port Charlotte section of our website and view the map that will show sections: http://www.suncoasteam.com/articles/75.html
Most of the descriptions will mention if the homes have these utilities, but I'd be happy to double check for you. Also, I can certainly run a report of homes with these services.
If you have questions please feel free to call or email.
