RE: Locating outfall
Have you considered speaking with city officials to aid in your search?
If there is no outfall it may be best to connect to an existing storm sewer network in your area vs creating another outfall. This method is generally preferred with the governing agencies.
Hope this helps.

Along the lines of the comments from CVG and Francesca, starting HGL information should be obtained from the agency that oversees the system (i.e. Previous studys, Agency Computer Models, previous project improvement plans). If you get lucky with your research, HGL data is sometimes plotted onto storm sewer improvement plans. I'm in the west coast and when there is a lack of better data, some agencies allow you to to assume the pipe to be half full. I personally prefer CVG's assumption and assume the pipe to be full. I would discuss it with the agency official/plan checker to see what assumption they would feel confortable with, specially if flooding or any drainage issues may have been observed.
