I have all my approvals on ZIMAS, even the new addresses, but my plans have been "awaiting approval by a Supervisor" for well over a month.Other reasons it is not popular are that with the amount of restrictions in LA it severely limits who can and should use it, the layout of your lot and existing conditions are very important in deciding if it makes sense to build.

Send the engineer the site plan/sketch showing system layout (if existing) and ask for half-hour to discuss options.

In the most recent BP forum layout, each post has a menu that offers a few options for what one might want to do with an existing post; "Quote" is the one to choose since it will copy the text of the post AND it will also notify the user that the post was being referenced - the mention to the author of the post is something that copy and paste does not generate. 

You want someone who does not only file your taxes, but also helps you lay out strategy for the next year - there is only so much you can do after the fact.
