Taxes
The best way to make money in SimCity 4 is through taxation, higher taxes mean more money to spend in building your city. Early in the game it is important to build the city up prior to spending a lot of money on amenities for your Sims to generate a good tax base. Keep tax levels at reasonable rates, if they are too high your Sims will move out.
Land Value
Land value is enhanced by the proximity to water and high ground (elevation-wise). This is your opportunity to make some places that will be higher in land value, and make your place popular among your citizens.
