I don't know the graceful answer, but I'll mention a workaround suggested by ESRI Tech support to me several months ago when I had some ongoing weirdness with File Geodatabase Schema locks.  Their solution was to run the "Compact" tool, which includes in its functioning a Schema lock release.  This cleaned up the issues on several FGDB. Important Note - the similar-sounding process in ArcCatalog (right-click on FGDB, Administration, Compact Geodatabase) does not include as comprehensive a Schema lock clearing, so use the tool instead.

While Network Analyst can solve many routing issues, I don't believe it currently includes a way to derive a route that does all the streets. However, there appears to be a third-party application available customized to this task.  I have no idea on its effectiveness, but it may be worth checking out: Street Sweeping & Snow Removal — Route Optimization Software | Routesmart Chris Donohue, GISP ...

What Darren says is so true in the Private Sector.  Business's will ask for much more than they need (or are willing to pay for). If they want 3 years or less, you can apply to these to try to land a first GIS job.  Don't be put off by the wording. Chris Donohue, GISP ... View more

Be aware that job requirements and willingness to hire someone who does not have all of them are treated differently between the Public and Private Sector. In the Public Sector (government), the listed requirements are usually treated as the absolute minimum.  Governments tend to require much more in the way of documented experience and education that the Private Sector for an equivalent job, to the point some would say of over-requiring abilities for a job. In the Private Sector (business), the requirements are more of a "wish-list".  Unless they state that the applicant absolutely must have a skill, they are usually open to hiring someone who has only some of them. Specifically, be aware that in the Private Sector they will take candidates who have only some of the skills they list in GIS,if the candidate also has education and/or skills specific to the business they are in.  For example, if you studied Economics and know GIS, that can be a way to get in to do GIS with firms that do Economic analysis.  So for Private firms, in your cover letter, application, and interview, be sure to bring up the relevant non-GIS areas where you can be of help to the business.

Another idea - not a complete solution but may help fill in some pieces to the puzzle. I.e. some food for thought: 1.  Split the line by the Parcels 2.  Convert the line to point at the center 3.  Run "Near" with a Searchdistance of 25ft.  May have to use the bearing information to avoid capturing a non-participating parcel at a right-angle crossing at a 4-way parcel intersection. Near ArcGIS Help 10.1 One immediate pitfall, though, is that the line may not be split often enough.  For example, if it travels to 20 feet to the "West" side of parcel 18-028005-0 it will not be split enough to capture the two parcels to the "East".

It's interesting that you are tackling this - I have a somewhat similar task on my "to do" list at this very moment in trying to update our City's Land Use layer versus the Parcels. Some basic ideas that I am toying with (as yet untested for this specific task): 1.  Convert your parcels from polygons to lines, then do a Spatial Join of your boundary line to the polygon line. 2.  Run a Select By Location to determine the relationships.

Joe's suggestion will work.  Primitive but effective  A couple more options: 1. XTools Pro (third-party software for ArcGIS) has a "Split Polygons" tool that will split them using a line.  You can download the demo version for free and try it out. http://www.xtoolspro.com/ 2.  Splitting a polygon by an overlapping feature ArcGIS Help (10.2, 10.2.1, and 10.2.2) Chris Donohue, GISP ...

Another question - is the road polyline essentially "cutting" the landcover polygons?  For example, if a road passes through a landcover polygon, do you need it break the polygon into 2 parts, using the road as a boundary? Chris Donohue, GISP ... View more

Another aspect that would help in figuring out a solution is the "why" part.  A vertice needs to be added, but what is driving this?  I'm not questioning the need to do this, but instead ask as oftentimes knowing the "why" opens up a whole different batch of solutions.

Some questions to help clarify the issue for troubleshooting: 1.  When you say you cannot display the joined data, do you mean after you export it?  Or Can you see the joined data by opening the attribute table before exporting? 2.  When you say the exported data comes up empty, can you confirm that not only are the joined attributes are missing but also missing are the original polygon attributes and the polygons are also missing?

I don't have a specific solution, but a few ideas to try: 1.  Check the Snap Tolerance.  Experiment with using a different tolerance just to see if that is what is throwing it. 2.  Start a new File Geodatabase and copy your feature classes there.  Then try the Split process.  If it works, it indicates the issue is likely something to do with your  feature classes being in SDE. 3.  Along the lines of #2, you can implement Jayanta's idea there, as unlike in SDE you have total control over the Schema (so can make the new fields needed).  Then if all goes well, move the results back to SDE.
