Most insist the screens be constructed from wooden privacy fence panels, concrete or brick walls, chain link fencing with privacy slats or other man-made materials.

Planners and site development reviewers rarely allow these screens to be created from plants.
Wooden and chain link fence panels are understandably predictable in behavior and provide instant opacity.
Plants on the other hand take time to grow, and if not maintained properly can present a challenge.
Ultimately, many city permitting staff take the easy way out and reject proposals using plants for screening requirements to a site development plan.

Yet there are some visionary site designers and municipal site plan reviewers, some who are willing to take a risk and allow plants to be used for infrastructure screening.
Plant screens can be highly effective, offering opacity and privacy. Additionally, plant screens clean stormwater, sequester carbon, produce oxygen, prevent erosion, provide habitat for urban wildlife and mitigate urban heat island effect.

Even more encouraging was the fact that the reviewing county agency approved the use of plants for a visual screen rather than wooden panels or galvanized chain link.
Kudos to the designers and to the permitting staff for allowing and even encouraging Urban Greening.
Hopefully we will see more native plant landscapes serve as site design elements in the Urban Core.
