Above all, involve the community, workshops where the views of all can shared are important to build the consensus needed to provide the support the planning commission and city council will need to have a effective zoning ordinance and when they attempt to change the status quo.
Consider carefully the use of pyramid zoning, where less intensive uses say residential, are allowed in commercial, as mentioned above. As the town matures, this type of zoning structure provides unwelcome surprises for new owners years in the future. A commercially zone tract of ground that is developed as apartments (which generally would be legal under pyramid zoning) may or may not be what is in the town's best interest. Beware of overzoning, overlaying commercial districts on existing residential areas because "they may become commercial". Let the market place determine when a home has more value as business site and have the developer get the change in zoning at that time.
