(OP)
Anyone know of a good storm sewer program using the tr-55 calc method that also includes calc. of hydraulic gradelines?

Haestad's StormCAD is expensive and good.
I've used both, neither is better than the other.

The "pipes" module allows you to design your storm sewer in a stick-figure format, and has built in tools to do most of the profile drafting, and puts all structure and pipe data into an MS Access database. This database can then be loaded into StormCAD to build most of the analysis model.
On the other hand, Hydraflow StormSewers is not a bad program and works just fine. It just doesn't integrate with Land Desktop.

Haestad's Civil Storm (www.haestad.com) or Streamline Technology's (www.streamnologies.com) ICPR utilizes SCS methodologies (what TR-55 is based on) and perform dynamic hydraulic analysis. There may be others.
The cost of Civilstorm ranges from $5k to $20k. The last time we purchased ICPR, I believe it was $3k for unlimited nodes.

Use the 5-minute rainfall duration -- this provides 500-1000 acres of raincloud size. Average rainfall intensity for the cloud is given in IDF curves.
If your site is relatively flat assume the best you can do is a flow velocity of 3-4 ft/sec.
Do not go above 6.0 ft/sec -- you will probably be surcharging manholes & CB's.

EPA SWMM could do both, and is !FREE!, but has a steep learning & setup curve.
