The Town does not prohibit any trees for Castle Rock residents. There are, however, some limitations for commercial/non-residential properties. Landscapers for those properties must stick to Castle Rock Water's approved plant list (PDF). Additionally, some homeowners associations (HOA) may have restrictions on tree types. Check with your individual HOA before starting a landscape project.
While the Town does not prohibit anything for residents, there are some recommendations. The Plant Finder at CRconserve.com is a great resource. Additionally, we discourage residents from planting anything highly flammable like juniper or spruce trees.
