Gotta be a culvert here somewhere

This could use some surveying - is there a culvert here? Or is this cut off? See also the canal at the end of Taylor Rd - is it connected or not?

Where does this stream come out?

All of this obviously has to go somewhere, where is the culvert?

The houses in this block have suspicious address tags that require some surveying to verify: the south end have e.g. 5300B and 5302 in a single building.

I would expect it to just be 5300 and 5302. On the north end, there is 5205 and 5205B, where there is room for the each unit to have its own numeric address.

This is no longer a parking lot, it is fenced off for future development
