I alway start with a blank terrain template and build the basics like my community service center site with an outdoor farmer's market and a larger homestead lot using the largest lot size for my first couple's home and place all of the needed items on the lots before starting to play like a lot visitor controller and other hacked objects to set things up so the market donesn't get swarmed with sims and it's usually deserted except for my playables and any other families I might've eventually moved in after the founders got their home built.I play the community as families get moved in so I start with one couple and eventually have more move in over time and the first ones also start trying for babies as the latest ones are moving in.
