Once you have got full density streets and zoned the whole map, how do you get your city to grow?

You mean all your buildings are high density? Then you can't, that's it. The only thing you can do now is outsource things(power, water, sewage, etc) to save space and thus zone more rci. Also, you may need to rezone some areas for balance.

 

If you have high density streets but buildings are not progressing you may need happiness(parks, services, etc) and/or just time for them to progress.

I do not profess to have extensive knowledge, so I may be wrong.  But this is my understanding:

 

Happiness allows your R to increase in density.  The best tool for this, in my experience, is the Mayor's Mansion: every time you upgrade it you add hapiness to every building in the city.  Stay on top of the upgrades and do them as quickly as possible.  However, it's kind of circular in that the way you upgrade is by having the requisite level of approval rating for the requisite amount of time.  I'm not sure, but it would seem to me that hapiness and approval rating are linked.  The other way to improve R hapiness is to ensure that they can shop.  So make sure you integrate your commercial zones with your residential so that they dont have to travel too far.  Parks and libraries act as 'shops' so you can plop down a few of them as well.

 

Profitability allows C and I to increase in density.  For C, you need to ensure there are enough shoppers, first and foremost.  For I, make sure there are workers and places to ship freight.

 

Healthiness (germs) and Crime Rates also impact on all types of hapiness.  The best way to see what people are concerned about is to click on the approval rating button and then mouse over each type of zone and you will get a break down by density type as to what people are concerned about.  Try and address these issues.

 

Good luck!
