Hi @nickbitsward :) There is a way if you use or are open to using a mod at least temporarily. Using the Nraas Debug Enabler mod you can send a sim around collecting just about anything by clicking on an object, debug enabler, options (name of item selected) and choose 'add to family inventory'. Then use that sim to build your park as residential to start, move the sim out then change the lot assignment.
You will find that the statues are sims sculpturified in brass and separate from their base, you'll need both parts. Cloning a statue yields an interesting result.
